The Fred Hutchinson Cancer Research Center began in 1975, with critical help from Washington State's U.S. Senator Warren Magnuson.
Fred Hutch quickly became the permanent home to Dr. E. Donnall Thomas, who had spent decades developing an innovative treatment for leukemia and other blood cancers. Thomas and his colleagues were working to cure cancer by transplanting human bone marrow after otherwise lethal doses of chemotherapy and radiation. At the Hutch, Thomas improved this treatment and readied it for widespread use. Since then, the pioneering procedure has saved hundreds of thousands of lives worldwide.
While improving bone marrow transplantation remains central to Fred Hutch's research, it is now only part of its efforts. The Hutch is home to five scientific divisions, three Nobel laureates and more than 2,700 faculty, who collectively have published more than 10,000 scientific papers, presented here as a full bibliography.
NOTE: From 1995 to 2009 I served as the Hutch's vice president for information technology — hence my interest in the organization. Although my role was in the admin division, if you dig through this bibliography, you will find a couple of papers with me as an author.

Age-Specific racial disparities in the incidence of fatal prostate cancer: an analytic deconstruction.
JNCI cancer spectrum pii:8300176 [Epub ahead of print].
BACKGROUND: Black men in the United States bear a disproportionate share of the prostate cancer (PCa) burden, with more than 50% higher incidence and double the mortality compared with White men. Previous studies have examined racial disparities in the incidence of fatal PCa (fPCa), defined as diagnosis leading to disease-specific death within 10 years and found that they are greater in younger versus older men. However, the extent to which these trends are driven by disparities in incidence or survival is unknown.
METHODS: We conduct a retrospective analysis of data from the Surveillance, Epidemiology, and End Results program over the period 1980-2009 to decompose the incidence of fPCa into incidence and 10-year probability of death and quantify the relative disparities in these metrics by age at diagnosis.
FINDINGS: We find that relative PCa incidence for Black versus White men significantly decreases by 0.116 units with each successive five-year age group (95% CI = -0.183 to -0.049) but the relative probability of death within 10 years does not differ significantly by age (slope = -0.012, 95% CI = -0.060 to 0.035). Further, this deconstruction is similar before and after the introduction of prostate-specific antigen screening.
CONCLUSION: We conclude that higher relative incidence of fPCa in young Black men vs young White men appears to be largely driven by their significantly increased incidence of disease. This finding supports investigating targeted screening of Black men beginning at younger ages than White men.

Collagen-binding IL-12-armoured STEAP1 CAR-T cells reduce toxicity and treat prostate cancer in mouse models.
Nature biomedical engineering [Epub ahead of print].
Immunosuppressive microenvironments, the lack of immune infiltration, and antigen heterogeneity pose challenges for chimaeric antigen receptor (CAR)-T cell therapies applied to solid tumours. Previously, CAR-T cells were armoured with immunostimulatory molecules, such as interleukin 12 (IL-12), to overcome this issue, but faced high toxicity. Here we show that collagen-binding domain-fused IL-12 (CBD-IL-12) secreted from CAR-T cells to target human six transmembrane epithelial antigen of prostate 1 (STEAP1) is retained within murine prostate tumours. This leads to high intratumoural interferon-γ levels, without hepatotoxicity and infiltration of T cells into non-target organs compared with unmodified IL-12. Both innate and adaptive immune compartments are activated and recognize diverse tumour antigens after CBD-IL-12-armoured CAR-T cell treatment. A combination of CBD-IL-12-armoured CAR-T cells and immune checkpoint inhibitors eradicated large tumours in an established prostate cancer mouse model. In addition, human CBD-IL-12-armoured CAR-T cells showed potent anti-tumour efficacy in a 22Rv1 xenograft while reducing circulating IL-12 levels compared with unmodified IL-12-armoured CAR-T cells. CBD fusion to potent payloads for CAR-T therapy may remove obstacles to their clinical translation towards elimination of solid tumours.

Molecular Risk Markers Define Risk of Relapse in Myeloid Leukemia of Down syndrome Beyond Measurable Residual Disease.
Blood advances pii:547870 [Epub ahead of print].
Myeloid leukemia of Down syndrome (ML-DS) is a distinct form of pediatric acute myeloid leukemia (AML) that responds to reduced intensity chemotherapy as compared to non-DS AML that requires intensive chemotherapy and often stem cell transplant. While most patients with ML-DS have a favorable prognosis, outcomes for those with refractory or relapsed disease are dismal. Children's Oncology Group (COG) study AAML1531 introduced the use of minimal residual disease measured by multi-parameter flow cytometry at the end of the first course of induction therapy (EOI-1 MRD) for risk stratification of treatment intensity. Of 280 ML-DS patients enrolled, 41 were classified as high risk (HR) due to positive EOI-1 MRD and treated with intensified chemotherapy similar to that used for pediatric non-DS AML. Treatment intensification did not improve the 2-year event-free survival compared to MRD-positive patients treated with reduced intensity therapy in predecessor study AAML0431(80.5 + 12.4% vs. 76%, p=0.247) or overall survival (80.5 + 12.4% vs. 76.2 + 18.6%, p=0.819), but significantly increased the frequency of febrile neutropenia and sepsis events. While stratification of treatment intensity based on MRD was not beneficial, molecular markers of relapse risk proposed by the Japan Children's Cancer Group for ML-DS (alterations of CDKN2A, ZBTB7A, JAK2, TP53) proved prognostic. Relapse risk was 50% in AAML1531 HR patients with any high risk molecular marker compared to 6.7% in those without. Similar relapse results were obtained in the MRD-negative AAML1531 group, suggesting molecular risk markers can predict outcome and thus be used to stratify therapy in ML-DS. https://clinicaltrials.gov/study/NCT02521493.

Sacituzumab Govitecan in Untreated, Advanced Triple-Negative Breast Cancer.
The New England journal of medicine [Epub ahead of print].
BACKGROUND: Patients with previously untreated, locally advanced, unresectable or metastatic triple-negative breast cancer who are not candidates for inhibitors of programmed cell death protein 1 (PD-1) or programmed death ligand 1 (PD-L1) have limited treatment options.
METHODS: In this international, phase 3, open-label, randomized trial, we enrolled patients with previously untreated, advanced triple-negative breast cancer who were not candidates for PD-1 or PD-L1 inhibitors owing to previous use or coexisting conditions. Patients had either PD-L1-negative tumors with a combined positive score (CPS; the number of PD-L1-staining tumor cells, lymphocytes, and macrophages divided by the total number of viable tumor cells, multiplied by 100) of less than 10 or PD-L1-positive tumors with a CPS of 10 or higher and were assigned in a 1:1 ratio to receive sacituzumab govitecan or chemotherapy (paclitaxel, nanoparticle albumin-bound paclitaxel, or gemcitabine plus carboplatin). The primary end point was progression-free survival, assessed by blinded independent central review. Secondary end points included overall survival, objective response, the duration of response, and safety.
RESULTS: Among 558 patients, median progression-free survival was 9.7 months (95% confidence interval [CI], 8.1 to 11.1) with sacituzumab govitecan and 6.9 months (95% CI, 5.6 to 8.2) with chemotherapy (stratified hazard ratio for disease progression or death, 0.62; 95% CI, 0.50 to 0.77; P<0.001). An objective response was confirmed in 48% of patients (95% CI, 42 to 54) who received sacituzumab govitecan and 46% (95% CI, 40 to 52) who received chemotherapy; the median response duration was 12.2 months (95% CI, 9.7 to 13.8) and 7.2 months (95% CI, 5.7 to 8.4), respectively. Adverse events of grade 3 or higher occurred in 66% of patients who received sacituzumab govitecan (most frequently neutropenia [in 43%], diarrhea [in 9%], and leukopenia [in 7%]) and in 62% of patients who received chemotherapy (most frequently neutropenia [in 41%], anemia [in 16%], and leukopenia [in 13%]). The incidence of adverse events that led to discontinuation of sacituzumab govitecan or at least one chemotherapy drug was 4% and 12%, respectively.
CONCLUSIONS: Sacituzumab govitecan led to significantly longer progression-free survival than chemotherapy among patients with advanced triple-negative breast cancer who were not candidates for treatment with PD-1 or PD-L1 inhibitors. The incidence of adverse events of grade 3 or higher with sacituzumab govitecan was similar to that with chemotherapy, but adverse events were common.

Genomic Alterations and Associated Outcomes in Patients with PSMA-Positive Metastatic Castration-Resistant Prostate Cancer treated with 177Lu-PSMA-617.
The oncologist pii:8297114 [Epub ahead of print].
BACKGROUND: 177Lu-PSMA-617 is approved for patients with metastatic castration-resistant prostate cancer (mCRPC). Although treatment is associated with improved outcomes, not all patients benefit and response is heterogeneous. We aim to characterize genomic alterations associated with benefit to 177Lu-PSMA-617.
METHODS: This study used the Prostate Cancer Precision Medicine Multi-Institutional Collaborative Effort (PROMISE) clinical-genomic database (n = 2445). The primary endpoint was ≥50% PSA decline (PSA50) from baseline with 177Lu-PSMA-617 in molecular subgroups. Secondary endpoints included 90% PSA decline (PSA90). Associations were assessed using Fisher's exact test and Cox regression in multivariable analysis.
RESULTS: We identified 183 mCRPC patients treated with 177Lu-PSMA-617. Median number of prior lines of mCRPC therapy was three. Overall, PSA50 was 49%, median progression-free survival was 7.6 months, and median overall survival was 13.9 months. NF1 (n = 8) and FOXA1 alterations (n = 5) were associated with increased PSA50 (88% vs. 47%, p = 0.03 for NF1; 100% vs. 47%, p = 0.03 for FOXA1). Among CRPC sequenced tumors (n = 119), androgen receptor (AR) alterations (n = 58) were associated with lower PSA50 (38% vs. 60%, p = 0.03). While any tumor suppressor genes (TSG) (PTEN, TP53, RB1) (n = 109) or TP53 (n = 83) alteration were associated with lower PSA90 (p = 0.02 for both), NF1 (n = 8) and FOXA1 alterations were associated with higher PSA90 (p = 0.03 and p = 0.003, respectively).
CONCLUSIONS: This analysis identifies potential genomic predictors of response to 177Lu-PSMA-617, with NF1 and FOXA1 alterations associated with favorable outcomes and AR and TSG alterations with diminished response. These hypothesis-generating findings suggest genomic profiling may inform selection for PSMA-targeted therapy and warrant prospective validation in larger cohorts.
IMPLICATIONS OF PRACTICE: In this study, we evaluate the use of genetic markers to predict response to treatment with 177Lu-PSMA-617 in patients with metastatic prostate cancer. We identified that alterations in the androgen receptor (AR) and tumor suppressor genes (TSG) were associated with a worse response to 177Lu-PSMA-617, which FOXA1 and NF1 alterations were associated with improved outcomes. These data are hypothesis generating and warrant validation in larger studies. Identifying predictive markers to 177Lu-PSMA-617 can better optimize treatment selection for this therapy.

Multicenter phase II trial of ipilimumab and nivolumab in metastatic or unresectable perivascular epithelioid cell tumor (PEComa): a substudy of Dual Anti-CTLA-4 and Anti-PD-1 blockade in Rare Tumors (DART) SWOG S1609 (Cohort 38).
Journal for immunotherapy of cancer, 13(10):.
BACKGROUND: Malignant perivascular epithelioid cell tumors (PEComas) are ultra-rare, aggressive mesenchymal neoplasms associated with poor outcomes. Standard-of-care systemic therapy includes mammalian target of rapamycin (mTOR) inhibition and chemotherapy. Immune checkpoint inhibition has not been previously studied in patients with advanced PEComas in a prospective clinical trial.
METHODS: This is an open-label phase 2 trial of ipilimumab (1 mg/kg intravenously every 6 weeks) plus nivolumab (240 mg intravenously every 2 weeks) in rare tumors; here we report the cohort of patients with advanced malignant PEComa recruited from >1,000 sites across the USA. Primary end point was objective response rate, with progression-free survival, overall survival, and toxicity as secondary end points.
RESULTS: 17 patients were enrolled (N=16 evaluable). Median age was 59.5 years (range, 22-77 years) and the majority were female (81%). Best responses included partial response (18.8%), stable disease for <6 months (25.0%), and progressive disease (56.3%). Median OS was 7.5 months (95% CI 3.4 to 34.6) and median PFS was 1.9 months (95% CI 1.8 to 11.8). PFS in responding patients was 11.8, 18.9, and 34.6 months. Available genomic sequencing showed TSC, ATRX, and TP53 mutations; no TFE3 fusions were identified (N=7). Nearly all patients experienced a treatment-related adverse event (AE) of any grade, while 37.5% experienced a grade 3-4 AE. Most common AEs were fatigue (43.8%), pruritus (37.5%), rash (25.0%), and aspartate aminotransferase increase (25.0%). There were no grade 5 AEs.
CONCLUSIONS: The combination of ipilimumab and nivolumab demonstrated responses in 18.8% of patients with advanced malignant PEComas. Dual immunotherapy may be an alternative treatment option for certain patients, including those who are unable to tolerate or do not desire prolonged treatment with chemotherapy or mTOR inhibition or have failed to respond to other therapies. Ipilimumab and nivolumab warrants further investigation in this and other rare soft tissue sarcomas.

abstract = {BACKGROUND: Malignant perivascular epithelioid cell tumors (PEComas) are ultra-rare, aggressive mesenchymal neoplasms associated with poor outcomes. Standard-of-care systemic therapy includes mammalian target of rapamycin (mTOR) inhibition and chemotherapy. Immune checkpoint inhibition has not been previously studied in patients with advanced PEComas in a prospective clinical trial.
METHODS: This is an open-label phase 2 trial of ipilimumab (1 mg/kg intravenously every 6 weeks) plus nivolumab (240 mg intravenously every 2 weeks) in rare tumors; here we report the cohort of patients with advanced malignant PEComa recruited from >1,000 sites across the USA. Primary end point was objective response rate, with progression-free survival, overall survival, and toxicity as secondary end points.
RESULTS: 17 patients were enrolled (N=16 evaluable). Median age was 59.5 years (range, 22-77 years) and the majority were female (81%). Best responses included partial response (18.8%), stable disease for <6 months (25.0%), and progressive disease (56.3%). Median OS was 7.5 months (95% CI 3.4 to 34.6) and median PFS was 1.9 months (95% CI 1.8 to 11.8). PFS in responding patients was 11.8, 18.9, and 34.6 months. Available genomic sequencing showed TSC, ATRX, and TP53 mutations; no TFE3 fusions were identified (N=7). Nearly all patients experienced a treatment-related adverse event (AE) of any grade, while 37.5% experienced a grade 3-4 AE. Most common AEs were fatigue (43.8%), pruritus (37.5%), rash (25.0%), and aspartate aminotransferase increase (25.0%). There were no grade 5 AEs.
CONCLUSIONS: The combination of ipilimumab and nivolumab demonstrated responses in 18.8% of patients with advanced malignant PEComas. Dual immunotherapy may be an alternative treatment option for certain patients, including those who are unable to tolerate or do not desire prolonged treatment with chemotherapy or mTOR inhibition or have failed to respond to other therapies. Ipilimumab and nivolumab warrants further investigation in this and other rare soft tissue sarcomas.},

Human monoclonal antibodies to HPV16 show evidence for common developmental pathways and public epitopes.
PLoS pathogens, 21(10):e1013086 pii:PPATHOGENS-D-25-00791.
Antibodies to human papillomavirus (HPV) primarily recognize surface exposed residues on five loops of the major capsid protein (L1) that vary significantly among HPV types. We determined which loops were required for neutralization for 68 HPV16 specific human monoclonal antibodies (mAbs) cloned from participants who received an HPV vaccine and describe molecular features of those antibodies. Chimeric HPV16 pseudovirus (cpsV), each having one surface loop bearing multiple amino acid substitutions, were used to determine neutralization specificity. The HPV16-FG-loop was the loop most frequently required for neutralization (42 of 68, 61.8%), however, all surface loops were required for neutralization by multiple mAbs: HI (13, 19.1%), DE (15, 22.1%), EF (five, 7.4%), BC (four, 5.9%). Antibodies that required multiple loops were common (17, 25.0%). Three mAbs (4.4%) required sequences on the c-terminus of L1 and for another three mAbs the neutralization specificity could not be determined. Two types of mAbs appeared to be overrepresented: ten mAbs used immunoglobin heavy chain variable region 2-70 (IGHV2-70) with immunoglobin light chain variable region 1-40 (IGLV1-40), having characteristic mutations in complementarity determining region two (CDRL2) of the light chain. Cryogenic electron microscopy (Cryo-EM) revealed that two of these antibodies bound five Fabs per capsomer interacting with all five L1-surface loops. The other type of mAbs that appeared to be overrepresented were nine mAbs using IGHV4-34, six of which also used DH3-16*02 with conserved CDRH3 sequences. Cryo-EM for one of these mAbs, that required the FG-loop for neutralization, was shown to bind one Fab per capsomer at the apex, interacting with the DE- and FG-loops, with sequences of the Fab CDRH3 inserted between the DE- and FG-loops from two L1 proteins. These two types of mAbs were found in the four participants suggesting that these antibodies shared developmental pathways and bound to similar immunodominant epitopes on the virus.

PseudotimeDE-fast: fast testing of differential gene expression along cell pseudotime.
Bioinformatics (Oxford, England) pii:8294116 [Epub ahead of print].
SUMMARY: Identifying differentially expressed (DE) genes along cell pseudotime is crucial for understanding dynamic biological processes captured by single-cell RNA sequencing. However, existing DE methods either produce invalid p-values by ignoring the uncertainty in pseudotime inference or struggle to scale with the growing size of modern datasets. To address these limitations, we introduce PseudotimeDE-fast, a scalable method for detecting DE genes along pseudotime with well-calibrated p-values. Through comprehensive simulations and real-data analyses, we demonstrate that PseudotimeDE-fast delivers comparable or superior performance to existing approaches while offering substantial improvements in computational efficiency.
AVAILABILITY: PseudotimeDE-fast is implemented in R with Rcpp acceleration and released under the MIT license. The source code is available at: https://github.com/dsong-lab/PseudotimeDE.
SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

Baseline use of aspirin or statins with oral estrogen and progestogens to prevent incident arterial or venous thrombotic events: a secondary analysis of the Women's Health Initiative trial.
Menopause (New York, N.Y.) [Epub ahead of print].
OBJECTIVE: To evaluate whether effects of oral hormone therapy (HT) on risks of venous and arterial vascular events differ by baseline statin or aspirin use.
METHODS: We performed time-to-event analysis using data from the Women's Health Initiative menopausal HT randomized trials to assess risk of thrombotic events. Women were randomized to oral conjugated equine estrogens (CEEs) alone or placebo among women with prior hysterectomy (n = 10,739), and CEE with medroxyprogesterone acetate (MPA) or placebo among women with an intact uterus (n = 16,608), stratified by baseline personal use of statins and aspirin. We evaluated risk of prespecified, adjudicated thrombotic events, including coronary heart disease, stroke, venous thromboembolism, and/or composite major adverse cardiovascular events, at 2 and 5 years.
RESULTS: Baseline statin use (n = 827 in CEE-alone trial; n = 1,115 in CEE+MPA trial) or aspirin use (n = 2,212; n = 3,431) was limited. At 5-year follow-up, coronary heart disease risk for CEE-alone versus placebo was hazard ratio (HR) = 0.81 (95% CI: 0.44-1.49) in statin users, similar to nonusers, HR = 1.07 (95% CI: 0.82-1.40). For CEE+MPA, there was also no difference by statin use, HR = 1.02 (95% CI: 0.55-1.89) and HR = 1.47 (95% CI: 1.13-1.90), respectively. Neither statin nor aspirin exposure significantly modified effects of HT on any arterial or venous thrombotic outcome at 2 or 5 years.
CONCLUSIONS: In this secondary randomized clinical trial analysis, neither statins nor aspirin significantly modified effects of oral HT on key arterial or venous thrombotic outcomes at 2 or 5 years. Results, however, may be underpowered given low baseline exposure prevalence for both statins and aspirin.

Validation of H5 influenza virus subtyping RT-qPCR assay and low prevalence of H5 detection in 2024-2025 influenza virus season.
Journal of clinical microbiology [Epub ahead of print].
A sustained outbreak of H5N1 influenza virus among wild fowl and domestic livestock has caused more than 70 zoonotic infections in humans in North America, including two deaths. The United States Centers for Disease Control and Prevention has recommended rapid H5 subtyping for all hospitalized cases with influenza A virus infection to enable prompt initiation of antiviral treatment, as well as infection prevention and implementation of public health measures to control spread. To address these needs, we developed a qualitative multiplex RT-qPCR assay to subtype H5 influenza virus in nasal, nasopharyngeal, and conjunctival specimens with a limit of detection of 250 copies/mL. No cross-reactivity was observed with other common respiratory viruses, including seasonal H3N2 and H1N1 influenza A viruses. We retrospectively subtyped 590 influenza A virus-positive clinical specimens with Ct values less than 31 processed by University of Washington labs between March 2024 and February 2025, including 512 specimens collected during the 2024-2025 influenza season, and detected no H5 positives. After clinical implementation, we performed 150 clinically ordered H5 subtyping tests between February and April 2025 and again detected no positives. This work enhances clinical pandemic preparedness activities and highlights the exceedingly low prevalence of H5N1 influenza virus during the 2024-2025 respiratory season.IMPORTANCEThe spread of H5N1 influenza virus in the United States has led to the culling of almost 200 million birds, infected cow herds across 17 states, and resulted in 70 human infections as of July 2025. Rapid PCR subtyping of H5 influenza virus is critical to inform hospital infection prevention and public health to enable containment of viral transmission. Here, we report the design, validation, and clinical implementation of a qualitative multiplex H5-subtyping RT-qPCR assay for nasopharyngeal, nasal, and conjunctival swab specimens. Additionally, we offer the largest reported study of H5 subtyping of influenza A virus-positive specimens in the United States to date. No H5 infections were detected in 740 samples collected between March 2024 and April 2025 from patients with confirmed influenza A virus infection in a large academic medical system in Seattle, WA.

Patient and Physician Perspectives on Using Risk Prediction to Support Breast Cancer Surveillance Decision Making.
Medical decision making : an international journal of the Society for Medical Decision Making [Epub ahead of print].
IntroductionBreast cancer survivors have a higher risk of interval cancers relative to the screening population. Patient characteristics including features of the primary cancer and its treatment can help predict interval second breast cancer risk, but patient and physician perspectives on how risk prediction tools might enhance surveillance decision making are not well characterized.DesignWe conducted a qualitative study of women with breast cancer who had completed primary treatment and multispecialty physicians recruited through Breast Cancer Surveillance Consortium registries. We conducted semi-structured focus groups with 5 to 7 breast cancer survivors and individual physician interviews. All participants were presented with information about an interval cancer risk prediction tool. We elicited participant perspectives on aspects of the tool's design, relevance, and use for surveillance decision making. Data coding, thematic analysis, and interpretation were guided by the principles of theoretical thematic analysis.ResultsForty physician interviews and 4 focus groups involving 23 breast cancer survivors were analyzed. Two prominent areas of focus emerged: 1) perspectives on how a risk prediction tool would enhance and add value to patient-centered care and 2) risk prediction tools can be a means to improve communication about risk of in-breast recurrence or new breast cancer.ConclusionsThis study provides data on breast cancer survivor and physician perceptions of a new risk prediction tool to support surveillance imaging decisions among breast cancer survivors.ImplicationsAn interval second breast cancer risk prediction tool may promote evidence-based care across an array of physicians and different clinical settings. Future research should identify care delivery settings and features that promote adoption and support use in ways that improve shared decision making and patient outcomes.HighlightsThis qualitative study of breast cancer survivors and physicians found that risk prediction tools to support surveillance decisions were perceived positively when positioned as a supplement to the patient-physician relationship.Both patients and physicians said that a tool supported by strong evidence and accessible outputs would be valuable for shared decision making.

A multicenter observational cohort study in survivors of Down Syndrome-associated acute leukemia (ALTE22C1): a report from the Children's Oncology Group.
BMC cancer, 25(1):1611.
BACKGROUND: Down syndrome (DS) is a common genetic disorder resulting from an extra copy of genetic material from all or part of chromosome 21. Individuals with DS have a higher burden of co-occurring structural birth defects, neurocognitive delay, and chronic health conditions when compared to those without DS, as well as a 10 to 20-fold excess risk for acute leukemia (AL). Few studies have reported the late effects of cancer treatment in DS-AL survivors, and even fewer have compared outcomes to children with DS and no cancer history. The Children’s Oncology Group study ALTE22C1 was developed to address this knowledge gap.
METHODS: This study leverages both registry and site-based DS-AL survivor recruitment and a prospective/retrospective cohort design to compare chronic health conditions and neurocognitive outcomes experienced by DS-AL survivors to age and sex-matched individuals enrolled to a DS cohort for which cancer is exclusionary. Survivors 6–39 years old, ≥ 3 years from end of AL treatment, and in remission are eligible. Participants complete a medical conditions survey and neuropsychological battery by parent proxy and may also participate in an in-person physical and neurocognitive assessment. Biological samples are collected to evaluate molecular features associated with outcomes.
DISCUSSION: This cooperative group study will identify the prevalence and severity of medical and neurocognitive outcomes in DS-AL survivors compared with non-DS AL and DS controls without cancer history.

abstract = {BACKGROUND: Down syndrome (DS) is a common genetic disorder resulting from an extra copy of genetic material from all or part of chromosome 21. Individuals with DS have a higher burden of co-occurring structural birth defects, neurocognitive delay, and chronic health conditions when compared to those without DS, as well as a 10 to 20-fold excess risk for acute leukemia (AL). Few studies have reported the late effects of cancer treatment in DS-AL survivors, and even fewer have compared outcomes to children with DS and no cancer history. The Children’s Oncology Group study ALTE22C1 was developed to address this knowledge gap.
METHODS: This study leverages both registry and site-based DS-AL survivor recruitment and a prospective/retrospective cohort design to compare chronic health conditions and neurocognitive outcomes experienced by DS-AL survivors to age and sex-matched individuals enrolled to a DS cohort for which cancer is exclusionary. Survivors 6–39 years old, ≥ 3 years from end of AL treatment, and in remission are eligible. Participants complete a medical conditions survey and neuropsychological battery by parent proxy and may also participate in an in-person physical and neurocognitive assessment. Biological samples are collected to evaluate molecular features associated with outcomes.
DISCUSSION: This cooperative group study will identify the prevalence and severity of medical and neurocognitive outcomes in DS-AL survivors compared with non-DS AL and DS controls without cancer history. Results are anticipated to inform clinical practice guidelines for DS-AL survivors and improve survivor outcomes through mitigation of outcome disparities in this vulnerable population.

Multiparametric breast MRI to problem-solve mammographically detected suspicious calcifications.
European journal of radiology, 194:112467 pii:S0720-048X(25)00553-4 [Epub ahead of print].
OBJECTIVE: To evaluate the performance of multiparametric breast MRI to problem-solve mammographically-detected suspicious calcifications.
MATERIALS AND METHODS: Participants with mammographically-detected suspicious calcifications were prospectively enrolled between August 2017 to May 2023. Pre-biopsy multiparametric MRI (standard and high-temporal resolution dynamic contrast enhanced [DCE]-MRI acquisitions and diffusion-weighted imaging [DWI]) was performed. The associations of MRI features with outcomes - (1) any malignancy and (2) invasive or high-grade ductal carcinoma in situ [DCIS] only - were analyzed using univariable logistic regression. Multivariable models, sequentially incorporating clinical/mammographic, qualitative, and quantitative features, were developed using penalized logistic regression with the least absolute shrinkage and selection operator. Area under the receiver operating characteristic curves (AUC) were estimated via cross-validation and compared between models using bootstrap methods.
RESULTS: 81 women (mean age, 55 years ± 10 [standard deviation]) with 86 calcifications were included; 29 % (25/86) were malignant. Malignancy rates for non-enhancing mammographic Breast Imaging Reporting and Data System (BI-RADS) category 4a and 4b calcifications were 3.8 % (1/26) and 8.7 % (2/23), respectively, with no invasive cancer or high-grade DCIS. Mammographic BI-RADS category, MRI BI-RADS category, visibility on DWI, peak percent enhancement, functional tumor volume, and K[trans] values were associated with both outcomes (all p < 0.05). Multivariable models, including qualitative DCE-MRI assessments, showed higher AUCs (malignancy: 0.71-0.76; invasive cancer or high-grade DCIS: 0.78-0.91) than when including only clinical and mammographic features (malignancy: 0.57; invasive cancer or high-grade DCIS: 0.61, all p < 0.05). Further incorporation of DWI or quantitative MRI features did not improve AUCs (all ΔAUC ≤ 0).
CONCLUSION: Breast DCE-MRI aids in evaluating mammographic BI-RADS category 4a/4b calcifications without biopsy. DWI or quantitative MRI features may not further improve diagnostic performance.

Prostate-specific membrane antigen positron emission tomography/computed tomography imaging as a precision diagnostic at prostate cancer recurrence after radical prostatectomy: Modeling long-term survival.
Cancer, 131(21):e70131.
BACKGROUND: Prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA-PET/CT) is affecting the management of patients with prostate cancer with biochemical recurrence after radical prostatectomy. The long-term outcomes of tailoring salvage treatment on the basis of PSMA-PET/CT status remain to be determined.
METHODS: A decision-analytic model was developed to project incremental life-years of strategies that allocate treatments at biochemical recurrence after radical prostatectomy on the basis of PSMA-PET/CT status (PSMA-metastatic vs. PSMA-nonmetastatic). Modeled treatments are local/regional (radiation) or systemic (hormone therapy and doublet therapy), administered immediately or delayed. PSMA-metastatic status was assumed to lead to treatment intensification, whereas PSMA-nonmetastatic status would lead to deintensification. To project survival, data on progression to metastasis from a clinical cohort were combined with registry data on postmetastasis survival. Because of the lack of data on long-term treatment benefits by PSMA status, survival was projected by varying the hazard ratio (HR) for disease-specific death among PSMA-metastatic versus PSMA-nonmetastatic patients under delayed or local/regional regimens (HR1) and under immediate systemic regimens (HR2).
RESULTS: Mean life-years are projected to be 15.5 under the non-PSMA-tailored strategy, and mean incremental life-years range from 0.38 to 0.81 depending on HR1 and HR2. A greater benefit is projected when PSMA-metastatic status is more adverse under salvage regimens that do not include systemic agents.
CONCLUSIONS: This decision-analytic modeling study projects that PSMA-PET/CT-guided management at biochemical recurrence after radical prostatectomy yields a modest survival benefit under the specified model inputs and assumptions regarding treatment distributions. These findings may complement emerging data on the corresponding economic costs and health-related quality of life.

Beamion BCGC-1: phase Ib/II trial of zongertinib for advanced HER2-positive breast or gastroesophageal cancers.
Future oncology (London, England) [Epub ahead of print].
BACKGROUND: Overexpression and/or amplification of human epidermal growth factor receptor 2 (HER2) is a recognized oncogenic driver in metastatic breast cancer (mBC) and metastatic gastric, gastroesophageal junction, or esophageal adenocarcinomas (mGEAC). Although HER2-directed monoclonal antibodies, antibody - drug conjugates (ADCs), and tyrosine kinase inhibitors (TKIs) have revolutionized the treatment of HER2-positive tumors, additional combination regimens and/or novel agents are needed to expand sequential therapy options and improve patient outcomes - particularly following treatment with trastuzumab deruxtecan (T-DXd). Zongertinib is a novel, irreversible, HER2-selective TKI that spares EGFR.
STUDY DESIGN: Here, we detail the rationale and design of Beamion BCGC-1 (NCT06324357), an international Phase Ib/II open-label trial in which patients with previously treated HER2-positive mBC or mGEAC will receive zongertinib alone or in combination. Phase Ib (dose escalation) will determine the maximum tolerated dose of zongertinib plus trastuzumab emtansine (T-DM1), T-DXd, or trastuzumab ± capecitabine, in patients with HER2-positive mBC, and plus T-DXd in patients with HER2-positive mGEAC. Phase II (dose optimization) will assess two doses of zongertinib in combination regimens, or as monotherapy, in patients with mBC or mGEAC. The trial is actively recruiting in six countries globally.

Chilling controversy: cold-stored platelets for prophylactic transfusions.
Blood, 146(17):2023-2028.
The US Food and Drug Administration recently licensed 14-day cold-stored platelets for bleeding patients. This policy change represents a reversal from the 1970s when cold-stored platelets were discontinued because of their short circulation time in healthy humans. This change will increase their availability in US hospitals with large trauma populations and in remote and rural settings in the United States. In some of these hospitals, cold-stored platelets will be the only platelets available. It is currently unclear whether patients with hypoproliferative thrombocytopenia who need platelet transfusion for prophylaxis benefit from cold-stored platelets. However, it is noteworthy that in recent clinical trials using room temperature-stored platelets, the transfusion interval in patients with hematologic and oncologic conditions can be as short as 1 transfusion per day, very similar to what one would expect to achieve with cold-stored platelets. Furthermore, the emphasis on the posttransfusion count increment and the platelet count as a transfusion trigger per se is questionable. In the PLADO trial, there was only a poor correlation between the morning platelet count and bleeding events, implicating other factors, such as red blood cells, coagulation factors, and vascular health, as possible culprits. In this perspective article, we review the history of cold platelets and the reason for their discontinuation, focus on recent clinical trial data using room temperature-stored platelets, and review the platelet count as a transfusion trigger. Overall, using cold platelets for prophylaxis may seem counterintuitive, but a closer look at the available data suggests that the indication expansion may hold more promise.

How I treat patients with CLL after prior treatment with a covalent BTK inhibitor and a BCL-2 inhibitor.
Blood, 146(17):2029-2036.
The treatment landscape for chronic lymphocytic leukemia (CLL) has been transformed by the advent of covalent Bruton tyrosine kinase (BTK) inhibitors (cBTKis) and B-cell lymphoma 2 (BCL-2) inhibitors, leading to markedly improved outcomes and, for many, near-normal life expectancy. However, patients progressing after both classes of therapy (double-refractory) have limited options and poor prognoses. This review outlines a practical approach to managing double-exposed or double-refractory CLL, incorporating clinical cases, trial data, and expert perspectives. For cBTKi intolerance, second-generation agents may remain effective. Venetoclax retreatment is reasonable after prior fixed-duration use. In true double-refractory disease, noncovalent BTK inhibitors (eg, pirtobrutinib) and CD19-directed chimeric antigen receptor T-cell (CAR-T) therapy (lisocabtagene maraleucel) are standard-of-care options. Pirtobrutinib induces rapid responses, though often of limited duration, underscoring the need for early consolidation planning with CAR-T or allogeneic stem cell transplant. Persistent disease after CAR-T therapy warrants close monitoring and timely transplant referral in eligible patients. Phosphoinositide 3-kinase inhibitors remain available but are limited by toxicity and modest benefit. Emerging agents, including BTK degraders, bispecific antibodies, and novel cellular therapies, offer promising future directions. Optimizing outcomes in double-refractory CLL requires an individualized, nuanced strategy integrating available treatments with innovative approaches under investigation.

Locityper enables targeted genotyping of complex polymorphic genes.
Nature genetics [Epub ahead of print].
The human genome contains many structurally variable polymorphic loci, including several hundred disease-associated genes, almost inaccessible for accurate variant calling. Here we present Locityper, a tool capable of genotyping such challenging genes using short-read and long-read whole-genome sequencing. For each target, Locityper recruits and aligns reads to locus haplotypes, for instance, extracted from a pangenome, and finds the likeliest haplotype pair by optimizing read alignment, insert size and read depth profiles. Across 256 challenging medically relevant loci, Locityper achieves a median quality value (QV) above 35 from both long-read and short-read data, outperforming state-of-the-art Illumina and PacBio HiFi variant calling pipelines by 10.9 and 1.7 points, respectively. Furthermore, Locityper provides access to hyperpolymorphic HLA genes and other gene families, including KIR, MUC and FCGR. With its low running time of 1 h 35 m per sample at eight threads, Locityper is scalable to biobank-sized cohorts, enabling association studies for previously intractable disease-relevant genes.

Across 256 challenging medically relevant loci, Locityper achieves a median quality value (QV) above 35 from both long-read and short-read data, outperforming state-of-the-art Illumina and PacBio HiFi variant calling pipelines by 10.9 and 1.7 points, respectively. Furthermore, Locityper provides access to hyperpolymorphic HLA genes and other gene families, including KIR, MUC and FCGR. With its low running time of 1 h 35 m per sample at eight threads, Locityper is scalable to biobank-sized cohorts, enabling association studies for previously intractable disease-relevant genes.},

Stockholm3 Versus Prostate-specific Antigen in Prostate Cancer Screening: 9-year Outcomes Demonstrating Improved Detection of Aggressive Cancers and Reduced Overdiagnosis from the STHLM3 Trial.
European urology pii:S0302-2838(25)04735-9 [Epub ahead of print].
BACKGROUND AND OBJECTIVE: Prostate-specific antigen (PSA) thresholds (≥3 or 4 ng/ml) are used to balance prostate cancer (PCa) detection against false positives; yet, aggressive PCa can occur at a low PSA and indolent tumors at a high PSA level. Long-term data clarifying aggressiveness across PSA thresholds are limited.
METHODS: The STHLM3 screening trial enrolled 59 088 men. All received PSA testing; those with PSA ≥1 ng/ml underwent the multianalyte Stockholm3 blood test. We analyzed men treated with radical prostatectomy or radiotherapy (n = 968). Outcomes were any biochemical recurrence (BCR), high-risk BCR, and PCa-specific mortality. Incidence across four baseline groups-(1) elevated PSA (≥3 ng/ml) and Stockholm3 (≥11), (2) elevated Stockholm3 alone (≥11), (3) elevated PSA alone (≥3 ng/ml), and (4) neither elevated PSA (<3 ng/ml) nor elevated Stockholm3 (<11)-was compared using Gray's test and competing-risk regression.
KEY FINDINGS AND LIMITATIONS: Follow-up was 8.9 yr. The 5-yr cumulative rates of any/high-risk BCR were as follows: 13%/9.0% for both elevated Stockholm3 (≥11) and elevated PSA (≥3 ng/ml), 9.4%/5.3% for elevated Stockholm3 alone, 1.5%/0% for elevated PSA alone, and 0%/0% for nonelevated results on both tests (p < 0.001). Compared with PSA-only elevation, Stockholm3-only elevation showed a hazard ratio (HR) of 1.8 (95% confidence interval 0.8-3.9; p = 0.2) for any BCR and an HR of 8.8 (1.06-72; p = 0.044) for high-risk BCR.
Some men with PSA <3 ng/ml harbor aggressive PCa with a substantial risk of recurrence after upfront curative treatment. Risk predictive blood tests, such as Stockholm3, used at lower PSA thresholds, can identify these men, while few clinically important cancers are missed when biopsy is deferred with PSA ≥3 ng/ml but low Stockholm3 scores.

Evaluating Long-term Health Disparity Impacts of Clinical Algorithms Using a Patient-level Simulation Framework.
Value in health : the journal of the International Society for Pharmacoeconomics and Outcomes Research pii:S1098-3015(25)05623-2 [Epub ahead of print].
OBJECTIVE: This study applies a simulation framework to evaluate the long-term effects of omitting race from a colon cancer decision algorithm for adjuvant chemotherapy, assessing impacts on health outcomes, costs, and disparities while accounting for measurement errors across racial groups.
METHODS: We developed a patient-level state-transition model using electronic health records from a large Southern California health system to project outcomes for 4,839 adults with stage II and III colon cancer post-surgery. We compared 30-year quality-adjusted life-years (QALYs), healthcare costs, and QALY distribution among racial groups under three chemotherapy treatment scenarios: 1) current practice, 2) treatment guided by an algorithm that includes race, and 3) the same algorithm with race omitted. An additional health state addressed racial bias in cancer recurrence ascertainment, and probabilistic sensitivity analysis (PSA) assessed uncertainty.
RESULTS: The clinical algorithm, compared to current practice, could improve average health by 0.048 QALYs and reduce racial health disparity by 0.20 QALYs at an incremental cost of $3,221, with the disparity gap decreasing in 96% of PSA iterations. Omitting race showed minimal effects on overall health or costs but resulted in 13% fewer Black patients receiving treatment, decreasing their QALYs by 0.07 and widening the disparity gap by 0.13 QALY. Health disparity increased in 94% of PSA iterations.
CONCLUSIONS: A cancer decision algorithm can improve population health and reduce health disparities, but omitting race may harm disadvantaged groups and limit reductions in disparities. Patient-level simulations can be routinely used to evaluate the potential health disparity impacts of algorithms before implementation.

Expression of programmed death ligand-1 and programmed cell death-1 across the anal neoplasia disease continuum and association with survival in anal cancer.
Modern pathology : an official journal of the United States and Canadian Academy of Pathology, Inc pii:S0893-3952(25)00216-9 [Epub ahead of print].
High-risk human papillomavirus (HPV) is associated with anal high-grade intraepithelial lesion (aHSIL) and anal squamous cell carcinoma (aSCC). The prognostic significance of PD-L1 expression in aSCC and its impact on overall survival (OS) is controversial. ASCC can evade immune surveillance by co-opting the PD-L1/PD-1 immune checkpoint pathway, enhancing tumorigenesis. To assess the potential role of the PD-L1/PD-1 axis on tumor progression, we assessed PD-L1 and PD-1 expression on epithelial cells and immune cells by immunohistochemistry in non-lesional anal tissue (n=22), aHSIL (n=22), and aSCC (n=52) from HIV-negative participants and people living with HIV. PD-L1 expression on epithelial cells was restricted to tumor cells with no expression in non-lesional and HSIL tissues, while PD-L1-positive immune cells were present across all three diagnostic stages. PD-1 expression was absent on epithelial cells whereas PD-1-positive immune cells increased along the disease continuum from non-lesional to aSCC. The overall PD-L1 expression on epithelial cells and immune cells measured by the combined positive score (CPS) in aSCC and the aggregate PD-L1 score in non-lesional and HSIL showed a substantial increase from non-lesional to aHSIL to aSCC. In aSCC, PD-L1 expression on immune cells was more prominent than in tumor cells and correlated with increased immune cell infiltration and interferon-gamma secretion. 92% of aSCC exhibited an adaptive PD-L1 expression pattern characterized by PD-L1 expression on tumors cells, immune cells or both. HIV status did not affect PD-L1/PD-1 expression in non-lesional, aHSIL or aSCC. PD-L1 expression in treatment naïve aSCC was associated with improved OS. Those with CPS of 0 had a higher risk of death [Hazard ratio 15.2 (95% CI: 3.3-69, p=0.0004; log-rank p<0.0001)] compared to those with CPS > 0. CPS may indicate the presence of immune activation and serve as a potential prognostic marker.

Tumor-infiltrating bacteria disrupt cancer epithelial cell interactions and induce cell-cycle arrest.
Cancer cell pii:S1535-6108(25)00402-7 [Epub ahead of print].
Tumor-infiltrating bacteria are increasingly recognized as modulators of cancer progression and therapy resistance. We describe a mechanism by which extracellular intratumoral bacteria, including Fusobacterium, modulate cancer epithelial cell behavior. Spatial imaging and single-cell spatial transcriptomics show that these bacteria predominantly localize extracellularly within tumor microniches of colorectal and oral cancers, characterized by reduced cell density, transcriptional activity, and proliferation. In vitro, Fusobacterium nucleatum disrupts epithelial contacts, inducing G0-G1 arrest and transcriptional quiescence. This state confers 5-fluorouracil resistance and remodels the tumor microenvironment. Findings were validated by live-cell imaging, spatial profiling, mouse models, and a 52-patient colorectal cancer cohort. Transcriptomics reveals downregulation of cell cycle, transcription, and antigen presentation genes in bacteria-enriched regions, consistent with a quiescent, immune-evasive phenotype. In an independent rectal cancer cohort, high Fusobacterium burden correlates with reduced therapy response. These results link extracellular bacteria to cancer cell quiescence and chemoresistance, highlighting microbial-tumor interactions as therapeutic targets.

Quantitative viral dynamics: Methods for parameter estimation.
Virology, 613:110631 pii:S0042-6822(25)00244-2 [Epub ahead of print].
Fitting mathematical models of viral dynamics to serial, quantitative viral load data provides inferences on the mechanisms in virus infection. This process can reveal the speed and magnitude of viral replication, cell proliferation and death, immune responses, and/or treatment efficacy. Viral dynamics modeling involves developing conceptual models, translating them into equations, and applying the appropriate statistical tools to determine the optimal parameters such that the model recapitulates observations from human and animal infections. In this review, we outline the theoretical foundations needed to understand model fitting, parameter estimation, and what it means to achieve a good fit. We provide examples and explain the strengths and limitations of three commonly used model fitting approaches: individual fitting, population mixed effects fitting, and feature fitting. We briefly review fitting algorithms and highlight powerful available computer software packages that can be used for fitting and parameter estimation. We discuss different model types, parameter identifiability, and how future modeling efforts can leverage advances in multi-dimensional data. Finally, we conclude with simple guidelines for choosing the best approach based on available data and scientific questions.

Changes in Medicaid Enrollment Among Adult Survivors of Childhood Cancer After Medicaid Expansion: A Report From the Childhood Cancer Survivor Study.
JCO oncology practice [Epub ahead of print].
PURPOSE: Little is known about whether Medicaid expansion under the Affordable Care Act affects insurance coverage among adult survivors of childhood cancer, a high-risk population requiring lifetime follow-up care. We examined the association of Medicaid expansion with Medicaid enrollment among participants in the Childhood Cancer Survivor Study.
METHODS: We identified 13,355 adult survivors (age 18-64 years) diagnosed with cancer at age <21 years between 1970 and 1999 and linked these survivors to Medicaid administrative data from 2010 to 2019. Outcomes included the percentage of survivors with any Medicaid enrollment and Medicaid-covered days (total number of days when a survivor was enrolled in Medicaid) each year. Multivariable difference-in-differences (DD) models were used to examine outcome changes (post- v pre-expansion) in expansion versus nonexpansion states.
RESULTS: Medicaid enrollment rates among survivors increased in expansion states (17.1% pre-expansion to 22.8% postexpansion) but decreased in nonexpansion states (16.6%-15.7%), leading to a net increase of 7.1 percentage points (ppts; 95% CI, 6.1 to 8.1). The DD model also showed a net mean increase of 18.7 days/year (95% CI, 15.0 to 22.4) in Medicaid-covered days in expansion relative to nonexpansion states. The expansion-associated increase in enrollment was greatest among survivors who were age 18-29 years (11.2 ppts; 95% CI, 8.3 to 14.1), non-Hispanic Black (13.6 ppts, 95% CI, 8.8 to 18.4) or Hispanic (13.4 ppts, 95% CI, 7.0 to 19.8), with <$20K in US dollars (USD) self-reported household income (13.5 ppts, 95% CI, 10.7 to 16.3), and noncollege graduates (9.3 ppts, 95% CI, 7.7 to 10.9). Similar patterns were observed when examining Medicaid-covered days.
CONCLUSION: To our knowledge, we provide the first evidence of increased Medicaid enrollment and longer coverage duration among adult survivors of childhood cancer after Medicaid expansion. Greater increases were seen among survivors from underrepresented racial/ethnic backgrounds, young adult survivors, and those with lower socioeconomic status, providing a mechanism to reduce disparities and ensure long-term medical care for childhood cancer survivors.

Diagnosis and Management of AML in Pediatric Patients: Consensus Recommendations from an International Expert Panel.
Blood pii:547835 [Epub ahead of print].
The European LeukemiaNet has periodically issued guidelines for the diagnosis and management of acute myeloid leukemia (AML) in adults. These consensus recommendations, most recently updated in 2022, incorporate recent advances in genomic testing, disease detection methods, target identification, and response assessment. Whilst similarities exist between AML in children and adults, pediatric AML is frequently characterized by unique cytogenetic and molecular features, which require distinct genetic and immunophenotypic diagnostics, therapeutic approaches, response assessment criteria, and supportive care strategies. To address these specific needs, an international panel of pediatric hematologist-oncologists, biologists, geneticists, and laboratory medicine scientists convened to develop recommendations for the diagnosis and management of AML in children, adolescents, and young adults (hereafter termed pediatric AML) that are discussed in this special report.

Investigating the HIV epidemic among Black gay and bisexual men in the Southern United States: Results of the HPTN 096 pilot cross-sectional assessment.
PloS one, 20(10):e0334031.
BACKGROUND: The HIV Prevention Trials Network (HPTN) 096 study was designed to address the markedly higher rates of HIV incidence among Black men who have sex with men (MSM) in the Southern United States (US). A cross-sectional assessment was conducted during the pilot phase of the study to determine its feasibility and collect key HIV-related metrics for the study population.
METHODS AND FINDINGS: Four hundred and twenty-two Black MSM, ≥ 15 years old and living in the four pilot communities (Dallas, TX; Houston, TX; Montgomery, AL; Greenville, SC), were enrolled via starfish sampling into the cross-sectional assessment. Each participant completed two questionnaires and had blood samples collected at a single study visit. Laboratory testing was performed to determine HIV status and use of oral pre-exposure prophylaxis (PrEP). HIV drug resistance and viral suppression were also assessed for two of the four pilot communities (Dallas and Houston). Categorical variables were summarized using frequency and percentage. Continuous variables were summarized using mean, standard deviation, median and interquartile range. Univariable and multivariable logistic regression models were used to assess various associations. HIV status was determined for 403 of the 422 participants (95.5%); 212 (52.6%) men were living with HIV, including one with acute HIV. For these participants, 163 (76.9%) reported that they were in HIV care. In Dallas and Houston, 71 of the 101 living with HIV (70.3%) were virally suppressed. Of the 191 not living with HIV, 57 (29.8%) reported ever taking PrEP, 41 (21.5%) reported being currently on PrEP, and eight (4.2%) reported never having heard of PrEP. PrEP use was documented through laboratory testing in 36 (19.1%) of 188 participants tested; of the 41 participants reporting current PrEP use, five did not have laboratory evidence of PrEP use.
CONCLUSION: During the pilot, we successfully recruited Black MSM using starfish sampling and demonstrated the feasibility of collecting primary study outcomes using a cross-sectional assessment. We found a high burden of HIV and those living with HIV had only a moderate rate of viral suppression. In addition, PrEP use was uncommon among the men living without HIV. Reducing HIV incidence in Black MSM remains a key element to addressing the HIV epidemic in the US.

abstract = {BACKGROUND: The HIV Prevention Trials Network (HPTN) 096 study was designed to address the markedly higher rates of HIV incidence among Black men who have sex with men (MSM) in the Southern United States (US). A cross-sectional assessment was conducted during the pilot phase of the study to determine its feasibility and collect key HIV-related metrics for the study population.
METHODS AND FINDINGS: Four hundred and twenty-two Black MSM, ≥ 15 years old and living in the four pilot communities (Dallas, TX; Houston, TX; Montgomery, AL; Greenville, SC), were enrolled via starfish sampling into the cross-sectional assessment. Each participant completed two questionnaires and had blood samples collected at a single study visit. Laboratory testing was performed to determine HIV status and use of oral pre-exposure prophylaxis (PrEP). HIV drug resistance and viral suppression were also assessed for two of the four pilot communities (Dallas and Houston). Categorical variables were summarized using frequency and percentage. Continuous variables were summarized using mean, standard deviation, median and interquartile range. Univariable and multivariable logistic regression models were used to assess various associations.

Advancing equity in cancer care: a pilot explanatory mixed methods study of a racially, ethnically, and linguistically concordant model of patient navigation.
Journal of health equity, 2(1):.
Disparities in cancer outcomes persist among systemically marginalized patients. A new racially, ethnically, or linguistically concordant (RELC) model of patient navigation (PN) was piloted at Fred Hutchinson Cancer Center in 2019. An explanatory mixed-methods observational study assessed patient-centered outcomes of RELC PN, traditional PN, and no PN. Patients from these models completed surveys at baseline and follow-up to measure changes in satisfaction, discrimination, resilience, stress, trust, and discussion of clinical trials. Interviews with patients receiving RELC PN were analyzed using thematic analysis. A total of 118 participants completed surveys. Satisfaction with care improved by 4.2 points (SD 7.0) on an 18-item 5-point Likert scale for those receiving RELC navigation, with no change in traditional or no PN groups. Discrimination based on race dropped from 40% (n = 2) to 20% (n = 1) in the RELC model. A higher proportion of RELC PN patients (80%; n = 4) discussed clinical trials compared to traditional PN (17%; n = 3) and no PN (20% n = 19). Thematic analysis of 29 interviews indicated the model was crucial in overcoming racism, improving trust, and empowering patients. This study highlights the potential of RELC PN to improve patient satisfaction, increase participation in clinical trials, and reduce experiences of discrimination.

Weighted Brier Score - an Overall Summary Measure for Risk Prediction Models with Clinical Utility Consideration.
Statistics in biosciences [Epub ahead of print].
As advancements in novel biomarker-based algorithms and models accelerate their use in disease risk prediction, it is crucial to evaluate these models within the context of their intended clinical application. Prediction models output the absolute risk of disease; subsequently, patient counseling and shared decision-making are based on the estimated individual risk and cost-benefit assessment. The overall impact of the application is referred to as clinical utility, which received significant attention and desire to incorporate into model assessment lately. The classic Brier score is a popular measure of prediction accuracy; however, it is insufficient for effectively assessing clinical utility. To address this limitation, we propose a class of weighted Brier scores that aligns with the decision-theoretic framework of clinical utility. Additionally, we decompose the weighted Brier score into discrimination and calibration components, and we link the weighted Brier score to the H measure, which has been proposed as an alternative to the area under the receiver operating characteristic curve. This theoretical link to the H measure further supports our weighting method and underscores the essential elements of discrimination and calibration in risk prediction evaluation. The practical use of the weighted Brier score as an overall summary is demonstrated using data from a prostate cancer study.

Influenza Antivirals for Prevention and Treatment in Immunocompromised People.
The Journal of infectious diseases, 232(Supplement_3):S243-S253.
Antivirals form a foundation for protecting immunocompromised individuals (ICIs) from influenza complications. Neuraminidase inhibitors have demonstrated benefit for both prophylaxis and treatment in ICIs, including when given >48 hours after symptom onset. Baloxavir is a newer antiviral that has potent effects on viral kinetics in immunocompetent people, but data on baloxavir in ICIs are currently limited. Optimization of antiviral therapy to minimize viral replication within ICIs and reduce the risk of treatment-emergent antiviral resistance (eg, through combination regimens) may prevent viral evolution within ICIs and mitigate transmission of virulent or resistant variants to the general public. Unfortunately, ICIs have been excluded from most clinical trials evaluating novel influenza preventive and therapeutic strategies. Inclusion of ICIs in such clinical trials is essential to facilitate acquisition of clinical and virologic data in patients with specific immunocompromising conditions and ensure that ICIs have equitable access to valuable interventions.

Limitations of acyclovir and identification of potent HSV antivirals using 3D bioprinted human skin equivalents.
Nature communications, 16(1):9200.
Herpes simplex virus (HSV) infection poses global public health concerns with lifelong impacts. Acyclovir, the standard therapy, has limited efficacy in preventing subclinical shedding, and drug resistance occurs in immunocompromised patients, highlighting the need for novel therapeutics. Here we show that acyclovir is significantly less effective in skin-derived keratinocytes than donor-matched fibroblasts. Using 3D bioprinted human skin equivalents (HSEs) in a 96-well plate format, we have screened 738 compounds with broad targets and mechanisms of action, identifying potent antivirals, including 23 known or experimental HSV treatments. Unlike acyclovir, antivirals against HSV helicase/primase or host replication pathways display similar potency across cell types and donor sources in both 2D and 3D models. The reduced potency in keratinocytes may explain acyclovir's limited clinical efficacy. Our 3D bioprinted HSE assay platform enables the integration of patient-derived cells early in drug development and offers a physiologically relevant approach for HSV drug discovery.

Genetic determinants and genomic consequences of non-leukemogenic somatic point mutations.
Nature communications, 16(1):9194.
Clonal hematopoiesis (CH) is defined by the expansion of a lineage of genetically identical cells in blood. Genetic lesions that confer a fitness advantage, such as leukemogenic point mutations or mosaic chromosomal alterations (mCAs), are frequent mediators of CH. However, recent analyses of both single cell-derived colonies of hematopoietic cells and population sequencing cohorts have revealed CH frequently occurs in the absence of known driver genetic lesions. To characterize CH without known driver genetic lesions, we use 51,399 deeply sequenced whole genomes from the NHLBI TOPMed sequencing initiative to perform simultaneous germline and somatic mutation analyses among individuals without leukemogenic point mutations (LPM), which we term CH-LPMneg. We quantify CH by estimating the total mutation burden. Because estimating somatic mutation burden without a paired-tissue sample is challenging, we develop a novel statistical method, the Genomic and Epigenomic informed Mutation (GEM) rate, that uses external genomic and epigenomic data sources to distinguish artifactual signals from true somatic mutations. We perform a genome-wide association study of GEM to discover the germline determinants of CH-LPMneg. We identify seven genes associated with CH-LPMneg (TCL1A, TERT, SMC4, NRIP1, PRDM16, MSRA, SCARB1).Functional analyses of SMC4 and NRIP1 implicated altered hematopoietic stem cell self-renewal and proliferation as the primary mediator of mutation burden in blood. We then perform comprehensive multi-tissue transcriptomic analyses, finding that the expression levels of 404 genes are associated with GEM. Finally, we perform phenotypic association meta-analyses across four cohorts, finding that GEM is associated with increased white blood cell count, but is not significantly associated with incident stroke or coronary disease events. Overall, we develop GEM for quantifying mutation burden from WGS and use GEM to discover the genetic, genomic, and phenotypic correlates of CH-LPMneg.

Impact of PSMA PET Staging on Initial Treatment in Newly Diagnosed Prostate Cancer.
Journal of nuclear medicine : official publication, Society of Nuclear Medicine pii:jnumed.125.270825 [Epub ahead of print].
Prostate-specific membrane antigen (PSMA) PET/CT has become a common staging modality for newly diagnosed high-risk and unfavorable intermediate-risk prostate cancer after showing improved sensitivity and specificity compared with conventional imaging in clinical trials. We aimed to assess the causal impact of PSMA PET staging on initial treatment selection in real-world practice. Methods: We used observational data from the U.S. Veterans Health Administration to emulate a randomized controlled trial in which patients with newly diagnosed, unfavorable intermediate-, high-, and very-high-risk prostate cancer from January 2022 to December 2023 would have been randomized to undergo either upfront [18]F- or [68]Ga-PSMA PET staging or conventional imaging ([99m]Tc bone scan and pelvic CT or MRI). Outcomes of interest included use of frontline androgen deprivation therapy (ADT), second-generation androgen receptor pathway inhibitors (ARPIs), radiotherapy, and radical prostatectomy. Weighted univariable Cox regression was performed to assess the effect of treatment group on each outcome, and 95% CIs were generated from 1,000 bootstrap replicates. Results: In total, 9,049 patients met the criteria for inclusion. PSMA PET staging was associated with higher rates of any ADT use relative to conventional staging (adjusted hazard ratio [aHR], 1.26; 95% CI, 1.19-1.44), higher rates of ARPI use (aHR, 1.52; 95% CI, 1.33-1.78), lower rates of prostatectomy (aHR, 0.69; 95% CI, 0.56-0.83), and no significant effect on the use of radiotherapy (aHR, 1.10; 95% CI, 0.99-1.25). Compared with patients with PSMA stage N0M0, ARPI use was more common in patients with PSMA stage N1M0 (aHR, 6.87; 95% CI, 5.41-8.73) and PSMA stage M1 (aHR, 10.13; 95% CI, 8.16-1.2.58). Patients with PSMA N1M0 disease were much less likely to undergo prostatectomy compared with PSMA N0M0. Conclusion: PSMA PET staging may be leading to fewer prostatectomies and higher use rates of ADT and ARPIs in the Veterans Health Administration.

Methods: We used observational data from the U.S. Veterans Health Administration to emulate a randomized controlled trial in which patients with newly diagnosed, unfavorable intermediate-, high-, and very-high-risk prostate cancer from January 2022 to December 2023 would have been randomized to undergo either upfront [18]F- or [68]Ga-PSMA PET staging or conventional imaging ([99m]Tc bone scan and pelvic CT or MRI). Outcomes of interest included use of frontline androgen deprivation therapy (ADT), second-generation androgen receptor pathway inhibitors (ARPIs), radiotherapy, and radical prostatectomy. Weighted univariable Cox regression was performed to assess the effect of treatment group on each outcome, and 95% CIs were generated from 1,000 bootstrap replicates. Results: In total, 9,049 patients met the criteria for inclusion. PSMA PET staging was associated with higher rates of any ADT use relative to conventional staging (adjusted hazard ratio [aHR], 1.26; 95% CI, 1.19-1.44), higher rates of ARPI use (aHR, 1.52; 95% CI, 1.33-1.78), lower rates of prostatectomy (aHR, 0.69; 95% CI, 0.56-0.83), and no significant effect on the use of radiotherapy (aHR, 1.10; 95% CI, 0.99-1.25). Compared with patients with PSMA stage N0M0, ARPI use was more common in patients with PSMA stage N1M0 (aHR, 6.87; 95% CI, 5.41-8.73) and PSMA stage M1 (aHR, 10.13; 95% CI, 8.16-1.2.58). Patients with PSMA N1M0 disease were much less likely to undergo prostatectomy compared with PSMA N0M0. Conclusion: PSMA PET staging may be leading to fewer prostatectomies and higher use rates of ADT and ARPIs in the Veterans Health Administration.},

Pediatric doxorubicin exposure induces persistent pathological changes in mice.
Toxicology and applied pharmacology, 505:117600 pii:S0041-008X(25)00376-X [Epub ahead of print].
Over 50 % of pediatric cancer patients undergo treatment with chemotherapy regimens containing anthracyclines, such as doxorubicin (DOX). However, the long-term effects of childhood DOX exposure remain poorly understood, and protective strategies are limited. To establish a mouse model that recapitulates the chronic health conditions in adult survivors of childhood cancer, 14-day-old C57BL/6N mice received DOX (2.5 mg/kg, twice weekly for 2 weeks, i.p.) and were monitored for 32 weeks. Pediatric DOX injection induced late cardiotoxicity including systolic and diastolic dysfunction, cardiac fibrosis and cardiomyocyte atrophy, which were alleviated by treatment with the CDK7/12/13 inhibitor THZ1. Pediatric DOX also reduced heart, liver and spleen weight, while sparing the lung and kidney. Mechanistically, DOX induced persistent activation of p38 in the heart and diminished physiological cardiomyocyte hypertrophy. Pediatric DOX caused slow body weight gain and late mortality, which were surprisingly exacerbated by THZ1. Notably, pediatric THZ1 exposure also hindered body weight gain and reduced heart and liver weight. In conclusion, pediatric DOX exposure resulted in chronic cardiac dysfunction, underweight and premature death during adulthood in mice. Pharmacologic inhibition of CDK7/12/13 with THZ1 partially protected against pediatric DOX-induced cardiotoxicity, but aggravated growth delay and accelerated mortality.

Five-Year Follow-Up Analysis of ZUMA-5: Axicabtagene Ciloleucel in Relapsed/Refractory Indolent Non-Hodgkin Lymphoma.
Journal of clinical oncology : official journal of the American Society of Clinical Oncology [Epub ahead of print].
Axicabtagene ciloleucel (axi-cel) is an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy approved for relapsed/refractory (R/R) follicular lymphoma (FL). Here, we report updated clinical outcomes from ZUMA-5 in 159 enrolled patients with R/R indolent non-Hodgkin lymphoma (iNHL; 127 with FL and 31 with marginal zone lymphoma) after a median follow-up of 64.6 months. Patients underwent leukapheresis and received lymphodepleting chemotherapy and axi-cel (2 × 10[6] CAR T cells/kg). The overall response rate was 90% (75% complete response rate). The median duration of response was 60.4 months, and the median progression-free survival (PFS) was 62.2 months; median time to next treatment and overall survival were not reached (NR). At data cutoff, 55% of patients were alive without requiring subsequent anticancer therapy. Median lymphoma-specific PFS in patients with FL was NR; 34% had progression or death due to lymphoma or study treatment. Notably, after 30 months postinfusion, progression or lymphoma-related deaths were rare. Late-onset toxicities were infrequent and largely unrelated to axi-cel. Durable response and prolonged survival in FL were associated with robust early CAR T-cell expansion and naïve product phenotype. These findings confirm sustained responses and manageable safety with axi-cel in the long term among patients with R/R iNHL and its potential as a curative therapy in FL.

T cell receptor specificity landscape revealed through de novo peptide design.
Proceedings of the National Academy of Sciences of the United States of America, 122(42):e2504783122.
T cells play a key role in adaptive immunity by mounting specific responses against diverse pathogens. Effective bindings between T cell receptors (TCRs) and pathogen derived peptides presented on major histocompatibility complexes (MHCs) mediate immune responses. However, predicting these interactions remains challenging due to limited functional data on T cell reactivities. Here, we introduce a computational approach to predict TCR interactions with peptides presented on MHC-I alleles, and to design immunogenic peptides for specified TCR-MHC complexes. Our method leverages HERMES, a structure-based machine learning model trained on the protein universe to predict amino acid preferences based on local structural environments. Despite no direct training on TCR-pMHC data, HERMES's implicit physical reasoning enables us to make accurate predictions of both TCR-pMHC binding affinities and T cell activities across diverse viral and cancer epitopes, achieving up to 0.72 correlation with experimental data. Leveraging our TCR recognition model, we develop a computational protocol for de novo design of immunogenic peptides. Through experimental validation in three TCR-MHC systems, we demonstrate that our designs-with up to five substitutions from the native sequence-activate T cells at success rates of up to 50%. Last, we use our generative framework to quantify the diversity of the peptide recognition landscape for various TCR-MHC's, offering key insights into T cell specificity. Our approach provides a platform for immunogenic peptide and neoantigen design, as well as for evaluating TCR specificity, offering a computational framework to inform design of engineered T cell therapies and vaccines.

Direct observation of interdependent and hierarchical kinetochore assembly on individual centromeres.
Nucleic acids research, 53(19):.
Kinetochores are megadalton protein machines that harness microtubules to segregate chromosomes during cell division. The kinetochores must assemble after DNA replication during every cell cycle onto specialized regions of chromosomes called centromeres, but the order and regulation of their assembly remains unclear due to the complexity of kinetochore composition and the difficulty resolving individual kinetochores in vivo. Here, by adapting a prior single-molecule method for monitoring kinetochore assembly in budding yeast lysates, we identify a sequential order of assembly and uncover previously unknown interdependencies between subcomplexes. We show that inner kinetochore assembly depends partly on outer kinetochore components, and that outer kinetochore branches do not assemble independently of one another. Notably, Mif2 assembly is a rate-limiting step that can be accelerated by binding to the Mtw1 subcomplex, thereby promoting rapid assembly of many inner and outer kinetochore components. The importance of controlling kinetochore assembly kinetics is supported by a Mif2 mutant lacking both autoinhibition and Mtw1 subcomplex binding activity, which leads to defective kinetochore-microtubule attachments when the centromeric histone variant Cse4 is overexpressed. Altogether, our work provides a direct view of kinetochore assembly and reveals highly interdependent regulatory events that control its order and timing.

Standardization of Measurable Residual Disease in Acute Myeloid Leukemia by Flow Cytometry: A Multicenter Study.
EJHaem, 6(5):e70163.
INTRODUCTION: Measurable residual disease (MRD) is a strong predictor of the risk of relapse of acute myeloid leukemia (AML). Therefore, for use in clinical decision-making, methods for MRD assessment must achieve adequate accuracy, sensitivity, specificity, and reproducibility. Multiparametric flow cytometry (MFC) is the most widely used method for assessing AML-MRD, but its sensitivity varies considerably due to the differing approaches used across centers, in addition to the different experiences of flow cytometrists, especially during clonal evolution. This study aimed to standardize AML-MRD by MFC in a multicenter project involving 16 Brazilian laboratories.
METHODS: In the first phase, specialists were trained in pre-analytical standard operating procedures (SOPs) and analysis strategies of pre-validated 8- and 10-color protocols, followed by a data-only, that is, a Dry Phase of flow cytometry standard (FCS) file exchange by the coordinating laboratory in a comparability assessment. In the second or Wet Phase, laboratories prepared and analyzed their samples, and the FCS files were submitted for central analysis.
RESULTS: The agreement of MRD results was 81% and 80% between laboratories and central analysts in the Dry and Wet Phases, respectively. However, non-suitable application of pre-analytical SOPs hampered MRD interpretation for 30% of the laboratories in the Wet Phase.
CONCLUSIONS: This study demonstrated that standardized flow cytometry protocols are reproducible as long as rigorous SOPs are implemented. The project's results underscore that continuous education and external quality control are essential to build expertise and ensure reliable AML-MRD results in clinical practice. Trial Registration:The authors have confirmed clinical trial registration is not needed for this submission.

Combining CAR T-Cell Therapy and Nivolumab to Overcome Immune Resistance in THRLBCL: A Case Report.
International journal of molecular sciences, 26(19):.
T-cell/histiocyte-rich large B-cell lymphoma (THRLBCL) is a rare, aggressive subtype of diffuse large B-cell lymphoma characterized by a profoundly immunosuppressive tumor microenvironment. PD-L1 overexpression by tumor cells is a recognized immune escape mechanism and may underlie resistance to cellular therapies, including CAR T-cell therapy. We report a case of a 29-year-old woman with refractory stage IV-B THRLBCL treated with anti-CD19 CAR T-cell therapy (varnimcabtagene autoleucel), who achieved an initial response (day +28) but experienced disease progression by day +100 despite robust CAR T-cell expansion. Peripheral blood analysis revealed persistent absolute B-cell aplasia, while bone marrow biopsy confirmed CD19-positive disease. Comparative immunohistochemistry demonstrated markedly increased PD-L1 expression in post-CAR T-cell samples, suggesting adaptive immune resistance via PD-1/PD-L1-mediated CAR T-cell inhibition. Nivolumab was initiated at month +4 to overcome this checkpoint-mediated resistance. Notably, a complete metabolic response was documented on PET/CT after four doses of nivolumab (month +6). The patient remains in sustained remission, with persistent B-cell aplasia, four years post-intervention. This case provides clinical and pathological evidence supporting the use of immune checkpoint blockade to rescue CAR T-cell efficacy, highlighting the potential of this synergistic approach in THRLBCL and possibly other B-cell malignancies exhibiting similar immune evasion.

Global burden of 292 causes of death in 204 countries and territories and 660 subnational locations, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.
Lancet (London, England) pii:S0140-6736(25)01917-8 [Epub ahead of print].
BACKGROUND: Timely and comprehensive analyses of causes of death stratified by age, sex, and location are essential for shaping effective health policies aimed at reducing global mortality. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023 provides cause-specific mortality estimates measured in counts, rates, and years of life lost (YLLs). GBD 2023 aimed to enhance our understanding of the relationship between age and cause of death by quantifying the probability of dying before age 70 years (70q0) and the mean age at death by cause and sex. This study enables comparisons of the impact of causes of death over time, offering a deeper understanding of how these causes affect global populations.
METHODS: GBD 2023 produced estimates for 292 causes of death disaggregated by age-sex-location-year in 204 countries and territories and 660 subnational locations for each year from 1990 until 2023. We used a modelling tool developed for GBD, the Cause of Death Ensemble model (CODEm), to estimate cause-specific death rates for most causes. We computed YLLs as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. Probability of death was calculated as the chance of dying from a given cause in a specific age period, for a specific population. Mean age at death was calculated by first assigning the midpoint age of each age group for every death, followed by computing the mean of all midpoint ages across all deaths attributed to a given cause. We used GBD death estimates to calculate the observed mean age at death and to model the expected mean age across causes, sexes, years, and locations. The expected mean age reflects the expected mean age at death for individuals within a population, based on global mortality rates and the population's age structure. Comparatively, the observed mean age represents the actual mean age at death, influenced by all factors unique to a location-specific population, including its age structure. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2·5th and 97·5th percentiles from a 250-draw distribution for each metric. Findings are reported as counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2023 include a correction for the misclassification of deaths due to COVID-19, updates to the method used to estimate COVID-19, and updates to the CODEm modelling framework. This analysis used 55 761 data sources, including vital registration and verbal autopsy data as well as data from surveys, censuses, surveillance systems, and cancer registries, among others. For GBD 2023, there were 312 new country-years of vital registration cause-of-death data, 3 country-years of surveillance data, 51 country-years of verbal autopsy data, and 144 country-years of other data types that were added to those used in previous GBD rounds.
FINDINGS: The initial years of the COVID-19 pandemic caused shifts in long-standing rankings of the leading causes of global deaths: it ranked as the number one age-standardised cause of death at Level 3 of the GBD cause classification hierarchy in 2021. By 2023, COVID-19 dropped to the 20th place among the leading global causes, returning the rankings of the leading two causes to those typical across the time series (ie, ischaemic heart disease and stroke). While ischaemic heart disease and stroke persist as leading causes of death, there has been progress in reducing their age-standardised mortality rates globally. Four other leading causes have also shown large declines in global age-standardised mortality rates across the study period: diarrhoeal diseases, tuberculosis, stomach cancer, and measles. Other causes of death showed disparate patterns between sexes, notably for deaths from conflict and terrorism in some locations. A large reduction in age-standardised rates of YLLs occurred for neonatal disorders. Despite this, neonatal disorders remained the leading cause of global YLLs over the period studied, except in 2021, when COVID-19 was temporarily the leading cause. Compared to 1990, there has been a considerable reduction in total YLLs in many vaccine-preventable diseases, most notably diphtheria, pertussis, tetanus, and measles. In addition, this study quantified the mean age at death for all-cause mortality and cause-specific mortality and found noticeable variation by sex and location. The global all-cause mean age at death increased from 46·8 years (95% UI 46·6-47·0) in 1990 to 63·4 years (63·1-63·7) in 2023. For males, mean age increased from 45·4 years (45·1-45·7) to 61·2 years (60·7-61·6), and for females it increased from 48·5 years (48·1-48·8) to 65·9 years (65·5-66·3), from 1990 to 2023. The highest all-cause mean age at death in 2023 was found in the high-income super-region, where the mean age for females reached 80·9 years (80·9-81·0) and for males 74·8 years (74·8-74·9). By comparison, the lowest all-cause mean age at death occurred in sub-Saharan Africa, where it was 38·0 years (37·5-38·4) for females and 35·6 years (35·2-35·9) for males in 2023. Lastly, our study found that all-cause 70q0 decreased across each GBD super-region and region from 2000 to 2023, although with large variability between them. For females, we found that 70q0 notably increased from drug use disorders and conflict and terrorism. Leading causes that increased 70q0 for males also included drug use disorders, as well as diabetes. In sub-Saharan Africa, there was an increase in 70q0 for many non-communicable diseases (NCDs). Additionally, the mean age at death from NCDs was lower than the expected mean age at death for this super-region. By comparison, there was an increase in 70q0 for drug use disorders in the high-income super-region, which also had an observed mean age at death lower than the expected value.
INTERPRETATION: We examined global mortality patterns over the past three decades, highlighting-with enhanced estimation methods-the impacts of major events such as the COVID-19 pandemic, in addition to broader trends such as increasing NCDs in low-income regions that reflect ongoing shifts in the global epidemiological transition. This study also delves into premature mortality patterns, exploring the interplay between age and causes of death and deepening our understanding of where targeted resources could be applied to further reduce preventable sources of mortality. We provide essential insights into global and regional health disparities, identifying locations in need of targeted interventions to address both communicable and non-communicable diseases. There is an ever-present need for strengthened health-care systems that are resilient to future pandemics and the shifting burden of disease, particularly among ageing populations in regions with high mortality rates. Robust estimates of causes of death are increasingly essential to inform health priorities and guide efforts toward achieving global health equity. The need for global collaboration to reduce preventable mortality is more important than ever, as shifting burdens of disease are affecting all nations, albeit at different paces and scales.

A Roadmap for the Future of Systems Biology in Cancer Research.
Cancer research pii:766667 [Epub ahead of print].
Cancer systems biology seeks to understand how cancer arises as a system of interconnected molecules, cells, and tissues, with the goal of understanding, predicting, and controlling the disease. In the last decade, the field has rapidly grown as advances in experimental, computational, and analytical technologies have improved our ability to capture and recapitulate the complexities of cancer at multiple scales. However, the field's promise to understand how specific molecular changes give rise to altered cancer outcomes remains incompletely fulfilled. Fortunately, an opportunity exists to accelerate progress by better coordinating modeling and data-gathering efforts across the cancer systems biology community. This will create the foundation for building accurate, multiscale cancer models that can better predict and identify improved therapeutic interventions. Here, we outline some of the current challenges in cancer systems biology research, how they can be addressed, and actions that the community can take to accelerate progress in the field.

Practical considerations and emerging approaches for the management of vasomotor and sexual symptoms in breast cancer patients on endocrine therapies.
Expert review of clinical pharmacology [Epub ahead of print].
INTRODUCTION: Vasomotor symptoms (VMS) and decreased libido are common menopausal symptoms. Patients with breast cancer receiving endocrine therapy experience new or worsening menopausal symptoms. Pharmacologic therapy for VMS has been centered on selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors, gabapentin, and clonidine. These therapeutic options fall short in obtaining adequate symptom relief, illustrating a therapeutic gap in efficacious treatment modalities. There are no historical systemic treatment options for low libido.
AREAS COVERED: This review summarizes the current pharmacologic therapy for VMS, focusing on the practical considerations for use of the novel VMS (fezolinetant, elinzanetant) and libido agents (flibanserin, bremelanotide). Literature search was completed with PUBMED, Cochrane Library, and Web of Science. Fezolinetant is a novel neurokinin 3 receptor antagonist that has demonstrated clinical benefit in patients without a history of breast cancer. For libido management, flibanserin and bremelanotide act as serotonin/dopaminergic modulators and melanocortin receptor agonists, respectively.
EXPERT OPINION: These novel agents are eagerly awaited therapeutic options; however, clinical trials excluded breast cancer patients. This review provides clinicians with relevant considerations to assess when recommending these therapies for patients with breast cancer, while awaiting ongoing research to give additional insights for best tailoring therapy for this patient population.

Perspective of Hispanic Cancer Survivors on Survivorship Care Plans: A Qualitative Study.
Journal of immigrant and minority health [Epub ahead of print].
Explore Hispanic cancer survivors' thoughts about survivorship care plans (SCPs), lay health educator (LHE)-delivered survivorship information, and general survivorship care among Hispanic cancer survivors. A subset of N = 95 participants (≥ 18 years) enrolled in a randomized controlled trial (RCT; March 2023 to August 2023) assessing the feasibility of LHE-delivered survivorship information completed phone-based interviews in which semi-structured guides probed their views on SCPs, the LHE call, and survivorship more broadly. Twenty participants (21% of the total enrolled) completed interviews (11 in English, 9 in Spanish). Most participants were female (70%), half were born in the United States (50%), and the majority had breast cancer (55%); the remaining had colorectal (5%), lymphoma (15%), and prostate cancers (25%). The average time since cancer diagnosis was 3.1 years (SD 1.8). Participants reported few issues transitioning from oncology to primary care and perceived that this transition was supported by easily accessible medical records that also help delineate the care responsibilities of different providers. Most participants thought the SCPs were easy to understand and helped them manage their survivorship care with confidence. They also found information on nutrition and physical activity helpful. Participants liked the LHE call but did not necessarily think it assisted with care coordination. Hispanic cancer survivors reported that the SCPs were helpful and easy to understand but that benefits of a survivorship-focused LHE session were less clear. Additional research may help to determine how best to utilize SCPs and LHEs for these survivors and their providers. Clinical Trials Registration: clinicaltrials.gov NCT04081779.

Cross-neutralizing and potent human monoclonal antibodies against historical and emerging H5Nx influenza viruses.
Nature microbiology [Epub ahead of print].
Highly pathogenic avian influenza H5Nx viruses are an emerging threat for global health, especially clade 2.3.4.4b H5N1 virus which causes panzootic infections. Here we describe the isolation and characterization of broadly cross-neutralizing monoclonal antibodies (mAbs) against diverse H5Nx viruses from individuals who received a monovalent H5N1 vaccine 15 years ago. By screening over 500 mAbs, we identified 5 mAbs that neutralized the majority of H5 clades including 2.3.4.4b and target three distinct conserved epitopes within the HA globular head. Cryo-electron microscopy structures of these mAbs in complex with HA, deep mutational scanning and neutralization escape studies define the sites of vulnerability of H5 HA. These mAbs mediated stronger prophylactic protection against clade 2.3.4.4b H5N1 infection in mice than the best-in-class mAb targeting the HA stem. Our study identified several highly potent broadly neutralizing H5 mAbs from humans that either alone or in combination provide a pragmatic pandemic preparedness option against the threat of panzootic H5N1 influenza.

A SARS-CoV-2 variant‑adjusted threshold of protection model for monoclonal antibody pre-exposure prophylaxis against COVID-19.
Nature communications, 16(1):9101.
Clinical development of monoclonal antibodies (mAbs) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is challenging due to rapid changes in the variant landscape. This study identified a threshold model for neutralising antibody (nAb) titres associated with clinically relevant protection against symptomatic COVID-19 for vulnerable populations. Using efficacy data from the phase 3 PROVENT pre-exposure prophylaxis trial of tixagevimab-cilgavimab (NCT04625725), individual nAb ID50 titres were predicted by dividing serum mAb concentration by prevalence-adjusted tixagevimab-cilgavimab potency (from in vitro IC50 values combined with viral surveillance data) and related to efficacy with a Cox model. The Threshold of Protection (ToP) Cox model was externally validated using data from the phase 3 SUPERNOVA trial (NCT05648110), which assessed sipavibart efficacy against symptomatic COVID-19 in immunocompromised participants. The PROVENT ToP model estimated the variant-specific observed efficacies from SUPERNOVA for 3 and 6 months post any dose with Lin's concordance of 0.86 and 0.75, respectively. This approach integrates predicted nAb ID50 titres against multiple SARS-CoV-2 variants into a ToP model that can be applied across different variants and could serve as a surrogate endpoint in immunobridging studies to expedite clinical evaluation and regulatory approval for mAbs targeting SARS-CoV-2.

Artemis: Mass Spectrometry-Based Identification of MHC-Presented Peptides Across Alleles, Classes, and Species Using Soluble Single-Chain MHC Constructs.
Methods in molecular biology (Clifton, N.J.), 2980:231-250.
The current "gold standard" for the identification of MHC-restricted peptides is conventional immunoprecipitation/mass spectrometry (MS); however, this approach requires a relatively large amount of sample, complex purification procedures, and computational analyses to assign peptides to individual alleles. Here, we provide instructions for the expression, purification, and MS identification of MHC-presented peptides of human and non-human, classical and non-classical, class I and class II proteins using a readily expressible, soluble, and easily purifiable single-chain dimer construct. This procedure enables the identification of up to tens of thousands of allele-specific peptides per run for peptidomics, ligandomics, therapeutic targeting, and motif analyses. Also included are instructions for construct design, streamlined lentiviral transfection and transduction, and computational methods for high-throughput processing of MS results, yielding high confidence peptide lists, motifs, and multiple analytics.

Investigating the causal effect of potential therapeutic agents for colorectal cancer prevention: a Mendelian randomization analysis.
Cancer epidemiology, biomarkers & prevention : a publication of the American Association for Cancer Research, cosponsored by the American Society of Preventive Oncology pii:766642 [Epub ahead of print].
BACKGROUND: Conventional observational studies have identified several potential therapeutic agents that may lower risk of colorectal cancer development. However, these studies are susceptible to unmeasured and residual confounding and reverse causation, undermining robust causal inference.
METHODS: We used Mendelian randomization (MR), a genetic epidemiological method that can strengthen causal inference, to evaluate the effect of previously reported therapeutic agents on colorectal cancer risk, including medications, dietary micronutrients, and exogenous hormones. Genetic instruments were constructed using genome-wide association studies (GWASs) of molecular traits (e.g. circulating levels of protein drug targets, blood-based biomarkers of micronutrients, circulating levels of endogenous hormones). Using summary statistics from these GWASs and a colorectal cancer risk GWAS (cases=78,473, controls=107,143), we employed Wald ratios and inverse-variance weighted models to estimate causal effects.
RESULTS: We found evidence for associations of genetically-proxied elevated omega-3 fatty acids (OR 1.10; 95% CI 1.03, 1.18; p=6.20x10-3) and reduced plasma ACE levels (OR 1.08; 95% CI 1.03, 1.13; p=9.36x10-4) with colorectal cancer risk. Findings for ACE inhibition were consistent across sensitivity analyses.
CONCLUSIONS: Reduced plasma ACE levels were robustly linked to increased colorectal cancer risk. Further work is required to better understand the mechanism behind this finding and whether this translates to adverse effects via medication use (i.e. ACE inhibitors).
IMPACT: These findings provide updated evidence on the role of previously reported therapeutic agents in colorectal cancer risk, helping to prioritise further evaluation of those agents with potential aetiological roles in cancer development.

Healthcare cost comparison between first-line ibrutinib and acalabrutinib in chronic lymphocytic leukemia patients in the Veterans Affairs.
Journal of comparative effectiveness research [Epub ahead of print].
Aim: Bruton's tyrosine kinase inhibitors (BTKis), including ibrutinib and acalabrutinib, transformed the treatment landscape of chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) by improving outcomes compared with chemoimmunotherapy. Real-world economic comparisons between BTKis are needed in diverse populations. This study aimed to compare healthcare costs in the Veterans Health Administration (VHA) among patients with CLL/SLL treated with, and remaining persistent on, first-line (1L) ibrutinib versus acalabrutinib monotherapy for 12 months. Materials & methods: This retrospective study used VHA electronic medical record data from January 2006 to July 2024. Eligible patients initiated 1L ibrutinib or acalabrutinib monotherapy on or after November 2019 and remained on continuous treatment for ≥12 months. All-cause and CLL/SLL-related costs were assessed over 12 months of follow-up. Generalized linear models were used to estimate adjusted costs and compare differences between treatment cohorts. Results: A total of 1059 patients were included (ibrutinib: n = 732; acalabrutinib: n = 327). During the 12-month follow-up of continuous 1L treatment, the annual adjusted all-cause total healthcare cost difference between ibrutinib and acalabrutinib was -$2422 (p = 0.46) (adjusted medical cost difference: $5259, p = 0.03; adjusted pharmacy cost difference: -$5886, p = 0.02). The annual adjusted CLL/SLL-related total healthcare cost difference between ibrutinib and acalabrutinib was -$3793 (p = 0.15) (adjusted medical cost difference: $2085, p = 0.05; adjusted pharmacy cost difference: -$5860, p = 0.02). Conclusion: Among VHA patients with CLL/SLL who initiated and remained on treatment with 1L BTKi monotherapy for 12 months, annual all-cause and CLL/SLL-related total healthcare costs were similar between ibrutinib and acalabrutinib. Pharmacy costs were lower for ibrutinib, while medical costs were lower for acalabrutinib, resulting in overall comparable total costs.

Comparing two different doses of inotuzumab ozogamicin treatment in adult patients with acute lymphoblastic leukemia: a plain language summary of publication.
Therapeutic advances in medical oncology, 17:17588359251370948 pii:10.1177_17588359251370948.
What is this summary about? This summary describes the results of a clinical study that compared two different doses of a treatment, called inotuzumab ozogamicin (inotuzumab for short), for acute lymphoblastic leukemia (ALL for short). This summary describes the results for people aged 18 years and older who took part in the study. Why was this study done? People who took part in the study had a higher risk of developing a side effect called sinusoidal obstruction syndrome (SOS for short), also known as veno-occlusive disease (VOD for short), which is a rare condition where some of the small blood vessels in the liver become blocked. Researchers wanted to find out if receiving a lower dose than the recommended dose of inotuzumab reduced the likelihood of people developing SOS after a stem cell transplant. Researchers wanted to find out if a lower dose of inotuzumab would also impact the efficacy (how well inotuzumab works to treat ALL) in people with ALL and what other side effects occurred.

What drives adolescent girls and young women's decisions to persist on PrEP? Results of a comparative qualitative study from a DREAMS program in western Kenya.
AIDS care [Epub ahead of print].
Oral pre-exposure prophylaxis (PrEP) is a valuable tool to help end HIV, but persistent PrEP use is low amongst adolescent girls and young women (AGYW) in sub-Saharan Africa (SSA), who are at high risk for HIV. To improve persistent PrEP use in AGYW, more research is needed to understand what drives their decisions to continue with PrEP. We conducted a thematic, comparative qualitative analysis of in-depth interviews with 32 AGYW who participated in PEPFAR's DREAMS program in western Kenya: 16 were randomly sampled among those who persisted with PrEP and 16 among those who discontinued. We compared results between these groups to explore drivers for the decision to persist with PrEP. We interpreted findings using the Integrated Behavior Model, which posits that the decision to persist is influenced by attitudes, social norms and personal agency. Three themes emerged that illuminated AGYW's decision to persist with PrEP. First, having positive attitudes towards PrEP was insufficient to ensure persistence in absence of correct knowledge. All AGYW were positive about PrEP, but those who discontinued often had insufficient/misinformation about PrEP, specifically on its appropriate use during pregnancy/breastfeeding. Second, support from family and friends was critical to overcome societal stigma and could counter lack of support from romantic partners. Third, strong mentors supported PrEP persistence by increasing self-agency, but this was secondary in importance to the need for robust knowledge and social support. To improve PrEP persistence amongst AGYW in SSA, PrEP programs may benefit from increasing education delivered to AGYWs and their communities, specifically family and friends. In particular, messages that PrEP may be used when pregnant/breastfeeding should be reinforced. Other health programs for AGYWs may also benefit from an increased focus on educational messaging to program recipients and people in their existing social networks.

Spike mutations that affect the function and antigenicity of recent KP.3.1.1-like SARS-CoV-2 variants.
Journal of virology [Epub ahead of print].
SARS-CoV-2 is under strong evolutionary selection to acquire mutations in its spike protein that reduce neutralization by human polyclonal antibodies. Here, we use pseudovirus-based deep mutational scanning to measure how mutations to the spike from the recent KP.3.1.1 SARS-CoV-2 strain affect cell entry, binding to the ACE2 receptor, RBD up/down motion, and neutralization by human sera and clinically relevant antibodies. The spike mutations that most affect serum antibody neutralization sometimes differ between sera collected before versus after recent vaccination or infection, indicating that these exposures shift the neutralization immunodominance hierarchy. The sites where mutations cause the greatest reduction in neutralization by post-vaccination or infection sera include receptor-binding domain (RBD) sites 475, 478, and 487, all of which have mutated in recent SARS-CoV-2 variants. Multiple mutations outside the RBD affect sera neutralization as strongly as any RBD mutations by modulating the RBD up/down movement. Some sites that affect RBD up/down movement have mutated in recent SARS-CoV-2 variants. Finally, we measure how spike mutations affect neutralization by three clinically relevant SARS-CoV-2 antibodies: VYD222, BD55-1205, and SA55. Overall, these results illuminate the current constraints and pressures shaping SARS-CoV-2 evolution and can help with efforts to forecast possible future antigenic changes that may impact vaccines or clinical antibodies.IMPORTANCEThis study measures how mutations to the spike of a SARS-CoV-2 variant that circulated in early 2025 affect its function and recognition by both the polyclonal antibodies produced by the human immune system and monoclonal antibodies used as prophylactics. These measurements are made with a pseudovirus system that enables safe study of viral protein mutations using virions that can only infect cells once. The study identifies mutations that decrease recognition by current human antibody immunity; many of these mutations are increasingly being observed in new viral variants. It also shows the importance of mutations that move the spike's receptor-binding domain up or down. Overall, these results are useful for forecasting viral evolution and assessing which newly emerging variants have reduced recognition by immunity and antibody prophylactics.

Overall, these results illuminate the current constraints and pressures shaping SARS-CoV-2 evolution and can help with efforts to forecast possible future antigenic changes that may impact vaccines or clinical antibodies.IMPORTANCEThis study measures how mutations to the spike of a SARS-CoV-2 variant that circulated in early 2025 affect its function and recognition by both the polyclonal antibodies produced by the human immune system and monoclonal antibodies used as prophylactics. These measurements are made with a pseudovirus system that enables safe study of viral protein mutations using virions that can only infect cells once. The study identifies mutations that decrease recognition by current human antibody immunity; many of these mutations are increasingly being observed in new viral variants. It also shows the importance of mutations that move the spike's receptor-binding domain up or down. Overall, these results are useful for forecasting viral evolution and assessing which newly emerging variants have reduced recognition by immunity and antibody prophylactics.},

IL-2/IL-15 signaling induces NK cell production of FLT3LG augmenting anti-PD-1 immunotherapy.
Cancer immunology research pii:766182 [Epub ahead of print].
Natural killer (NK) cells play a critical role in anti-cancer immunity through their direct cytotoxicity and production of cytokines, such as Flt3L. NK cell production of Flt3L controls conventional type I dendritic cell (cDC1) abundance in the tumor and promotes protective immune responses. Here, we show that NK cell production of Flt3l in the tumor is regulated by activation, and that activation by IL-2 and IL-15 uniquely induced Flt3L expression in NK cells. In melanoma, IL-2 signaling in NK cells led to increased Flt3L production, which boosted cDC1 abundance in the tumor and improved anti-PD-1 immunotherapy response. Further, NK cell subsets differentially regulated Flt3L in the tumor, with CD11b-CD27+ NK cells in mouse tumors enriched for IL-2-family signaling and upregulated Flt3l upon activation. Consistently, human CD56brightCD16- NK cells more strongly correlated with cDC1 and FLT3LG expression than other NK cell subsets across multiple human melanoma datasets and cancer indications. This mechanistic study of NK cell regulation of FLT3LG and control of the NK cell-cDC1 axis provides insights and strategies for the development of more effective cancer immunotherapies.

Circulating tumor DNA level is associated with time to clinical recurrence in Merkel cell carcinoma: Implications for patient management.
Journal of the American Academy of Dermatology pii:S0190-9622(25)02991-3 [Epub ahead of print].
BACKGROUND: Merkel cell carcinoma (MCC) recurs in 40% of patients. Circulating tumor DNA (ctDNA) is an emerging blood-based biomarker for early MCC recurrence detection.
OBJECTIVE: To evaluate the timing and prognostic significance of ctDNA levels relative to clinical recurrence.
METHODS: This multicenter prospective study analyzed 669 tumor-informed ctDNA tests from 215 MCC patients (stage I-IV) without clinically evident disease after treatment.
RESULTS: Patients with at least one positive ctDNA test were more likely to experience recurrence compared to ctDNA-negative patients (hazard ratio: 18.1, 95% CI: 8.9-36.7), with 77% developing clinically evident disease by one year. The median interval between the first positive ctDNA and clinical recurrence was 2.7 months. Clinical recurrences usually occurred within 3 months for ctDNA levels above 10 molecules/mL, within 6 months for levels between 1-10 molecules/mL, and within 9 months for levels below 1 molecule/mL.
LIMITATIONS: In this real-world study, there was variability in timing and frequency of follow-up examinations, imaging, and ctDNA testing, although most patients were followed with both ctDNA and imaging.
CONCLUSIONS: A positive ctDNA test detects MCC recurrence approximately 3 months earlier than imaging. Negative ctDNA can help reduce imaging frequency through serial ctDNA monitoring, while positive ctDNA warrants closer patient follow-up.

Using gene-environment interactions to explore pathways for colorectal cancer risk.
EBioMedicine, 121:105964 pii:S2352-3964(25)00408-6 [Epub ahead of print].
BACKGROUND: Colorectal cancer (CRC) is a significant public health concern, highlighting the critical need for identifying novel intervention targets for its prevention.
METHODS: We conducted genome-wide interaction analyses for 15 exposures with established or putative CRC risk [body mass index (BMI), height, physical activity, smoking, type 2 diabetes, use of menopausal hormone therapy, non-steroidal anti-inflammatory drugs, and intake of alcohol, calcium, fibre, folate, fruits, processed meat, red meat, and vegetables], and used interaction estimates to explore pathways and genes underlying CRC risk. The adaptive combination of Bayes Factors (ADABF), and over-representation analysis (ORA) were used for pathway analyses, and findings were further investigated using publicly available resources [hallmarks of cancer, Open Targets Platform (OTP)].
FINDINGS: A total of 1973 pathways using ADABF, and 840 pathways using ORA, out of the 2950 analysed, were enriched (P < 0.05) for at least one exposure, as well as 1227 genes within the enriched pathways. Data were available for 811/1227 coding genes in the OTP, 241 of which were supported by strong relative abundance of prior evidence (overall OTP score > 0.05). Fifty percent of the genes (617/1227) mapped to at least one hallmark of cancer, most of which (388/617) pertained to the Sustaining Proliferative Signalling hallmark. Our findings reflect previously established pathways for CRC risk and highlight the emerging importance of several less studied genes. Common pathways were found for several combinations of exposures, potentially suggesting common underlying mechanisms.
INTERPRETATION: The results of the present analysis provide a basis for further functional research. If confirmed, they may help elucidate the etiological associations between risk factors and CRC risk and ultimately inform personalized prevention strategies.
FUNDING: This study was funded by Cancer Research UK (CRUK; grant number:PPRCPJT∖100005) and World Cancer Research Fund International (WCRF; IIG_FULL_2020_022).

Intermediate-risk Non-muscle-invasive Bladder Cancer: Recommendations for Definitions, Risk Stratification, Management Strategies, and Clinical Trial Design from the International Bladder Cancer Group.
European urology oncology pii:S2588-9311(25)00223-8 [Epub ahead of print].
BACKGROUND AND OBJECTIVE: Intermediate-risk (IR) non-muscle-invasive bladder cancer (NMIBC) is a heterogeneous disease, and standardized definitions and risk-guided management are critical for appropriate patient care and clinical trial development.
METHODS: A global committee of bladder cancer experts developed IR-NMIBC recommendations. Working groups reviewed literature and drafted recommendations, which were voted on by International Bladder Cancer Group (IBCG) members using a modified Delphi process. During an August 2024 meeting, voting results and evidence were presented, and recommendations were refined. Final recommendations achieved >75% agreement.
KEY FINDINGS AND LIMITATIONS: The IBCG recommends inclusion of only low-grade (LG; G1 and G2) tumors in the IR-NMIBC category, risk stratified using the IBCG IR-NMIBC risk scoring system. Given the relatively indolent course and treatment burden of IR-NMIBC, therapeutic deintensification with active surveillance or office-based ablation is appropriate for select patients. Morbidity related to transurethral resection of a bladder tumor can be mitigated by forgoing restaging resection in completely resected LG tumors and not mandating muscularis propria sampling. Perioperative chemotherapy reduces recurrences, and additional adjuvant intravesical treatment should be risk stratified. Clinical trials evaluating novel IR-NMIBC therapies, including adjuvant and ablative designs, should incorporate patient-reported outcomes and risk-stratified controls. Ablative trials, as proof-of-concept studies for efficacy, require randomized controlled studies in the adjuvant setting to confirm superiority over the standard of care.
The IBCG consensus recommendations provide practical guidance for clinical care and clinical trial design for patients with IR-NMIBC.

A pragmatic pre-post intervention trial to address adherence to lung cancer screening follow-up in community settings (the ACCELL trial): Study protocol.
Contemporary clinical trials pii:S1551-7144(25)00300-3 [Epub ahead of print].
BACKGROUND: Lung cancer remains the leading cause of cancer death in the United States. Annual lung cancer screening (LCS) with low-dose chest CT (LDCT) can prevent lung cancer deaths in high-risk individuals; However, these benefits are tempered by low adherence to annual screening and low rates of follow-up for those with abnormal findings.
OBJECTIVE: To evaluate the impact of centralized approaches to care coordination on LCS follow-up in community settings through a hybrid implementation-effectiveness trial.
METHODS: This is a pre-post intervention trial of a pragmatic and flexible approach to LCS care coordination delivered at the system-level at two community LCS programs based at regional hospitals in Washington state. Care coordination approaches include standardized LCS follow-up workflows incorporating universal tracking of LCS results, universal results delivery to patients, stepped approaches to follow-up reminders and personalized approaches to positive findings. Participants who are eligible for and undergo LCS during either period (n ~ 6750) will be included. Primary outcomes include adjusted changes in screening adherence to annual follow-up and follow-up for positive findings between the pre- (August 2022-January 2025) and post- (January 2025-July 2027) intervention period. Secondary outcomes include assessing the impact of interventions by community site, patient ethnicity, socioeconomic status, and rurality. We will also assess the implementation of the intervention with attention to adaptation, sustainability and equity.
DISCUSSION: Implementing centralizing care coordination models may decrease barriers and improve adherence to LCS in community settings and serve as a model to improve LCS follow-up in clinical care settings.

Optimizing post-transplantation cell therapies to enhance graft-versus-leukemia effects in hematological malignancies.
Current opinion in immunology, 97:102675 pii:S0952-7915(25)00151-7 [Epub ahead of print].
Allogeneic hematopoietic cell transplantation (HCT) can cure patients with high-risk hematologic malignancies. Donor T and natural killer (NK) cells contribute to graft-versus-leukemia (GVL) effects that provide relapse protection. Post-HCT relapses often represent inadequate GVL, but alloreactive lymphocytes that confer GVL may also cause graft-versus-host-disease (GVHD). Here, we review recent developments to selectively augment GVL while minimizing GVHD. Insights into the unique mechanisms of post-HCT T cell dysfunction highlight interventions to enhance GVL-mediating T cells. Early clinical data suggest that adoptive transfer of engineered donor T cells, expressing either transgenic T cell receptors specific for minor histocompatibility antigens presented exclusively on recipient hematopoietic cells or chimeric antigen receptors binding surface proteins on malignant cells, can mitigate post-HCT relapse. NK cells, key GVL mediators after haploidentical HCT, can be induced into a highly functional memory-like state and administered to HCT recipients to enhance GVL. These innovations promise much-needed improvements in post-HCT outcomes.

Optimizing Asparaginase Treatment for Adolescent and Young Adult (AYA) Patients With Acute Lymphoblastic Leukemia: US Consensus Panel Recommendations.
American journal of hematology [Epub ahead of print].
Asparaginase is an integral component of therapy for pediatric patients with acute lymphoblastic leukemia/lymphoblastic lymphoma. The success of asparaginase-containing regimens has led to trials of pediatric/pediatric-inspired regimens incorporating asparaginase for treating adolescent and young adult (AYA) and adult populations with acute lymphoblastic leukemia/lymphoblastic lymphoma. While treatment of AYA patients with these regimens is associated with improved clinical outcomes compared with adult-specific protocols, AYA patients face unique challenges with these treatments, further complicated by a rapidly evolving therapeutic landscape. In this article, we identify barriers and other feasibility issues associated with administering asparaginase-based treatment to AYA patients and provide recommendations from a consensus panel of experts to optimize AYA patient outcomes and experiences. Barriers identified include the limited access to clinical trials and specialized expertise in pediatric-inspired regimens for AYA patients compared with pediatric patients, the complex management of asparaginase toxicities, limited medical facilities and experienced staff to administer and manage pediatric-inspired regimens, and reduced AYA patient access/adherence to treatment due to lifestyle-related or psychosocial challenges. Recommendations are provided on addressing and managing these challenges to improve asparaginase-based treatment accessibility and safety in AYA patients, including specific recommendations for high-risk populations.

PURPOSE: Modifying calibration conditions of linear accelerators is infrequent and potentially a high-risk procedure. This study outlines a systematic approach used to transition a linear accelerator's calibration condition in an active clinical environment from source-to-surface (SSD) to source-to-axis (SAD), while maintaining treatment accuracy and avoiding interruption of clinical operations.
METHODS: A satellite clinic within a university radiation oncology service operated an Elekta Versa HD linear accelerator with SSD calibration, while other system C-arm accelerators used SAD. With a single installation of the treatment planning system used across all sites, it was decided to convert the machine to SAD calibration. Representative plans with diverse delivery techniques were comprehensively evaluated in advance. Over a single weekend, beams were recommissioned in the treatment planning system (TPS), and output was adjusted per AAPM's TG-51 protocol. Monitor units (MUs) for on-treatment patients were scaled manually in the oncology information system, MOSAIQ. Quality assurance (QA) checks, as well as independent peer-reviewing of each field, were performed to ensure safety and quality for this high-risk procedure. A retrospective failure modes and effects analysis (FMEA) was subsequently conducted. To evaluate the clinical relevance and broader impact of this work, a targeted survey was conducted via the Wayne State MedPhysUSA LISTSERV.
RESULTS: As a result of the change in output calibration condition, field MU required scaling, ranging from 2.7% to 6.4%. Patient-specific QA measurements demonstrated consistent gamma pass rates, and both solid-water phantom and external audit results verified machine output accuracy within 2%. No patient treatments were interrupted during the process. The FMEA identified insufficient expertise and staffing as the highest-risk failure mode. Survey results indicated that 80% of respondents had never personally performed a calibration transition with patients on treatment, and the majority of respondents characterized the procedure as extremely rare and of higher risk than standard TG-51 annual QA.
CONCLUSIONS: The absolute output calibration condition was successfully transitioned from SSD to SAD without interruptions of patient treatments. Multiple verification steps were implemented to ensure quality and safety. This project contributed to improved standardization across multiple sites of practice.

Multiplex Digital PCR Assay Targeting DNA Methylation for Early Detection of Cancer.
Methods in molecular biology (Clifton, N.J.), 2969:29-42.
Digital PCR has been demonstrated to enable the precise nucleic acid absolute quantification across a wide range of applications. Historically, dPCR technology was limited to two channels for fluorescence detection. Recent advances in digital PCR have made it possible to multiplex and allow for simultaneous analysis of multiple targets within a PCR reaction. Here, we describe a multiplex dPCR assay for the detection and quantification of methylated DNA (also known as DNA-methylation-specific multiplex digital PCR, or DNA-methylation specific dPCR). We also demonstrate the application of this technology for the development of a candidate DNA methylation-based biomarker panel for the early detection of high-grade dysplasia and esophageal adenocarcinoma. Further, we discuss common technical challenges and troubleshooting for performing successful DNA-methylation-specific MS-dPCR assays.

Developing SEMA4A-directed CAR T cells to overcome low BCMA antigen density in multiple myeloma.
Cancer cell pii:S1535-6108(25)00399-X [Epub ahead of print].
Chimeric antigen receptor (CAR) T cell therapy targeting B cell maturation antigen (BCMA) for multiple myeloma (MM) is effective, but relapses associated with low-to-negative BCMA expression are common, indicating the need for additional targets. We quantitatively profile antigen density in a cohort of patients relapsed after BCMA CAR T therapy, showing high number of SEMA4A molecules/cell where BCMA density is low. SEMA4A deletion limits MM cell growth, migration, tissue infiltration, and osteoclast formation, while extending mouse survival. We generate monoclonal antibodies targeting SEMA4A-extracellular domain for CAR construction, screen engineered T cells for expansion, cytokine release, and cytotoxicity against MM cells. Lead constructs lack reactivity against normal non-hematopoietic tissues. SEMA4A CAR T cells show superior efficacy than BCMA CAR T cells eliminating patient-derived BCMA[low] tumors and MM cells progressing under suboptimal doses of BCMA CAR T cells. This study prepares for a phase 1 clinical trial with SEMA4A-directed CAR T cells for MM.

Germinal center-mediated broadening of B cell responses to SARS-CoV-2 booster immunization.
Science immunology, 10(112):eadu4107.
Germinal centers (GCs) are key sites for antibody diversification and affinity maturation. SARS-CoV-2 messenger RNA (mRNA) vaccines elicit robust GC B cell responses in humans, but how these responses influence the breadth of immunity against viral variants remains unclear. We analyzed GC B cell responses in nine healthy adults after mRNA booster immunization. We show that 77.8% of the B cell clones in the GC expressed representative monoclonal antibodies (mAbs) recognizing the spike protein, with 37.8% of these targeting the receptor binding domain (RBD). One RBD-targeting mAb, mAb-52, neutralized all tested SARS-CoV-2 strains, including the recent XEC variant. mAb-52 used the IGHV3-66 public clonotype, protected hamsters challenged against the EG.5.1 variant, and targeted the class I/II RBD epitope, closely mimicking the binding footprint of ACE2. Its broad reactivity was driven by extensive somatic hypermutation, underscoring the critical role of GC reactions in shaping cross-variant B cell immunity after SARS-CoV-2 booster vaccination.

Advances in Adipose Tissue Biology.
Endocrine reviews pii:8251365 [Epub ahead of print].
Adipose tissue has emerged as a central regulator of human physiology, with its dysfunction driving the global rise in obesity-associated diseases, such as type 2 diabetes, cardiovascular and liver diseases, and several cancers. Once thought to be inert, adipocytes are now recognized as dynamic, responsive cells essential for energy homeostasis and interorgan communication, including the brain. Distinct adipose depots support specialized functions across development, sex, and aging. Technologies like single-cell RNA sequencing are unraveling depot-specific mechanisms, with the potential of identifying new therapeutic targets. This review highlights major scientific advancements leading to our current appreciation of the pivotal role of adipose tissue in health and disease. Many key discoveries in this field have been catalyzed by National Institutes of Health funding, particularly through the National Institute of Diabetes, Digestive and Kidney Diseases, now celebrating its 75th anniversary.

Stratifying Lung Adenocarcinoma Risk with Multi-ancestry Polygenic Risk Scores in East Asian Never-Smokers.
medRxiv : the preprint server for health sciences.
BACKGROUND: Lung adenocarcinoma (LUAD) in never-smokers is a major public health burden, especially among East Asian women. Polygenic risk scores (PRSs) are promising for risk stratification but are primarily developed in European-ancestry populations. We aimed to develop and validate single- and multi-ancestry PRSs for East Asian never-smokers to improve LUAD risk prediction.
METHODS: PRSs were developed using genome-wide association study summary statistics from East Asian (8,002 cases; 20,782 controls) and European (2,058 cases; 5,575 controls) populations. Single-ancestry models included PRS-25, PRS-CT, and LDpred2; multi-ancestry models included LDpred2+PRS-EUR128, PRS-CSx, and CT-SLEB. Performance was evaluated in independent East Asian data from the Female Lung Cancer Consortium (FLCCA) and externally validated in the Nanjing Lung Cancer Cohort (NJLCC). We assessed predictive accuracy via AUC, with 10-year and (age 30-80) absolute risks estimates.
RESULTS: The best multi-ancestry PRS, using East Asian and European data via CT-SLEB (clumping and thresholding, super learning, empirical Bayes), outperformed the best East Asian-only PRS (LDpred2; AUC=0.629, 95% CI:0.618,0.641), achieving an AUC of 0.640 (95% CI:0.629,0.653) and odds ratio of 1.71 (95% CI:1.61,1.82) per SD increase. NJLCC Validation confirmed robust performance (AUC =0.649, 95% CI: 0.623, 0.676). The top 20% PRS group had a 3.92-fold higher LUAD risk than the bottom 20%. Further, the top 5% PRS group reached a 6.69% lifetime absolute risk. Notably, this group reached the average population 10-year LUAD risk at age 50 (0.42%) by age 41, nine years earlier.
CONCLUSIONS: Multi-ancestry PRS approaches enhance LUAD risk stratification in East Asian never-smokers, with consistent external validation, suggesting future clinical utility.

The impact of JAK1 pathogenic variants and MHC-I expression on response to immune checkpoint inhibition in endometrial cancer.
Clinical cancer research : an official journal of the American Association for Cancer Research pii:766176 [Epub ahead of print].
PURPOSE: Immune checkpoint inhibitors (ICI) have increasing application in endometrial cancer, underscoring the need for robust biomarkers for patient selection. JAK1 pathogenic variants (PV) have previously been implicated in immune evasion. Here, we identify biomarkers predictive of ICI response in endometrial cancer and the implications of JAK1 PV in this context.
EXPERIMENTAL DESIGN: This is a translational study of tumors from 84 endometrial cancer patients treated with ICI. High-throughput proteomic-based profiling was used to quantify 193 phospho-/protein expression levels, including key JAK/STAT signaling pathway components. Associations with clinical outcomes were assessed using multivariate regression analysis. The functional consequences of JAK1 PV were explored through in vitro signaling assays and analyses of TCGA database.
RESULTS: MHC-I expression correlated with improved progression-free survival (p = 0.035), validated in orthogonal approaches. Notably, a subset of patients harboring JAK1 PVs demonstrated exceptional survival on ICI. In TCGA cohort of microsatellite instability-high (MSI-H) and DNA polymerase epsilon (POLE)-mutated tumors, homozygous loss of JAK1 (JAK1Hom) trended toward decreased survival, whereas heterozygous loss of JAK1 (JAK1Het) was associated with significantly improved survival (p = 0.026), suggesting partial retention of antigen presentation pathways. Among our ICI-treated MSI-H tumor samples, NK cell marker NCAM1 was associated with improved survival (p=0.02).
CONCLUSIONS: These data support MHC-I as a potential predictive biomarker for ICI response in endometrial cancer. Additionally, we show that partial retention of JAK1 signaling in JAK1Het tumors is associated with improved survival, potentially attributable to enhanced NK cell activity in tumors with low MHC-I expression.

In TCGA cohort of microsatellite instability-high (MSI-H) and DNA polymerase epsilon (POLE)-mutated tumors, homozygous loss of JAK1 (JAK1Hom) trended toward decreased survival, whereas heterozygous loss of JAK1 (JAK1Het) was associated with significantly improved survival (p = 0.026), suggesting partial retention of antigen presentation pathways. Among our ICI-treated MSI-H tumor samples, NK cell marker NCAM1 was associated with improved survival (p=0.02).
CONCLUSIONS: These data support MHC-I as a potential predictive biomarker for ICI response in endometrial cancer. Additionally, we show that partial retention of JAK1 signaling in JAK1Het tumors is associated with improved survival, potentially attributable to enhanced NK cell activity in tumors with low MHC-I expression.},

Long-term follow-up of dose-dense brentuximab vedotin, ifosfamide, carboplatin and etoposide in second-line treatment of relapsed/refractory classical Hodgkin lymphoma.
British journal of haematology, 207(4):1599-1603.
This study presents the 5-year outcomes of a phase 1/2 trial (NCT02227199) evaluating dose-dense brentuximab vedotin (BV) combined with ifosfamide, carboplatin and etoposide (ICE) as second-line therapy in patients with relapsed classic Hodgkin lymphoma (cHL). Forty-five patients received at least one dose of BV-ICE, with the intention to proceed to autologous stem cell transplantation (ASCT). At a median follow-up of over 5 years, the progression-free survival was 77% (95% CI, 66%-91%) and overall survival was 91% (95% CI, 82%-100%). Of 37 patients who underwent ASCT, five relapsed; two received subsequent allogeneic transplantation and remain alive. Among eight patients who did not proceed to ASCT, four remain in complete remission long-term. Second malignancies developed in five patients post-ASCT, including two localized skin cancers and three non-skin cancers. These findings highlight BV-ICE as a highly active salvage regimen for relapsed cHL, with durable remissions in a majority of patients. The regimen may be especially relevant in the modern era for patients who relapse after Programmed Cell Death Protein 1 (PD-1) inhibitor-based front-line therapy and require additional treatment prior to planned ASCT.

Composition of carotid plaques differs between Chinese and US patients: a histology study.
Chinese neurosurgical journal, 11(1):23.
BACKGROUND: The clinical manifestations of cerebrovascular disease are known to differ between the Chinese and United States (US) populations as do the plaque features on imaging.
OBJECTIVES: The aim of this study was to investigate and compare the histological features of excised carotid plaques from Chinese and US patients.
METHODS: Carotid endarterectomy specimens collected from two prospective studies were included. The entire plaque was serially sectioned (10-µm thickness) at 0.5-1 mm intervals. Hematoxylin and eosin staining and Mallory's trichrome staining were performed. The morphology and components of the plaques were measured and compared between the two groups.
RESULTS: A total of 1152 histological sections from 75 Chinese patients and 1843 sections from 111 US patients were analyzed. The Chinese group had significantly smaller minimum lumen diameters (median: 1.1 vs. 1.3 mm, p = 0.046) and a larger percent wall volume (median: 74% vs. 70%, p = 0.018) than the US group. After adjusting for confounding factors, carotid plaques in the Chinese population had larger lipid pools (β = 10.0%, 95% CI: 4.9 to 15.9%), more recent intraplaque hemorrhage (IPH; β = 8.4%, 95% CI: 4.5 to 12.7%), less late IPH (β = - 8.2%, 95% CI: - 11.3 to - 5.4), and fewer fibrous cap disruptions (45% vs. 67%, p = 0.061). Chinese plaques were more homogeneous and had a higher percentage of plaques with features of xanthomas than did US plaques (20% vs 2.7%, p < 0.001).
CONCLUSIONS: The histology of Chinese plaques differs significantly from that of U.S. plaques, suggesting substantial differences in the pathophysiology of atherosclerotic cerebrovascular disease between Chinese and North American populations, which indicates a need for a different management approach.

Clinical Significance of a Multicancer Screening Trial With Stage-Based End Points.
JAMA network open, 8(10):e2536247.
IMPORTANCE: The first randomized screening trial of a multicancer early detection test is ongoing, with the primary end point being the incidence of late-stage cancer. The unprecedented use of a stage-based end point and short 3-year follow-up raise questions about how results should be interpreted and used in developing multicancer screening policy.
OBJECTIVE: To estimate outcomes of the trial and to identify information from the estimates that may aid in interpreting results of short-term trials evaluating multicancer screening tests.
This multicancer decision-analytic model estimated outcomes from registry data from the England National Cancer Registration and Analysis Service for cases diagnosed between January 2013 and December 2018. This model simulated a population-based multicancer screening trial of average-risk participants without a prior cancer diagnosis. The analysis was performed between April 2024 and April 2025.
INTERVENTIONS: Three annual multicancer screenings at months 0, 12, and 24. Cancers were assumed detectable 1 or 2 years before clinical diagnosis based on a published analysis, and cancer-specific early-stage sensitivities were set to either 100% or 50% of published sensitivities among clinically diagnosed cases.
MAIN OUTCOMES AND MEASURES: Reductions in late-stage (stage III-IV) cancer incidence over 3 years, cancer mortality over 5 years, and contributions of each cancer type to reductions in late-stage incidence and cancer mortality across the range of detectable intervals and early-stage sensitivities.
RESULTS: The model simulated 70 000 participants per arm (screening and control; median age, 66 years), and estimated that the overall late-stage incidence reductions at 3 years ranged from 6% to 23%, with corresponding reductions in 5-year cancer mortality from 6% to 9%. Colorectal cancer contributed the most to the reduction in late-stage incidence (28% to 39%), while lung cancer contributed the most to mortality reduction (40% to 42%).
CONCLUSIONS AND RELEVANCE: This independent decision-analytic model study found that the trial could achieve nontrivial cancer downstaging over 3 years, but modest mortality reduction over 5 years. These results were due to a limited number of target cancer types, underscoring the importance of transparent reporting of outcomes by cancer type, consideration of mortality implications, and careful preplanning for subsequent evaluation steps by the cancer research community.

Pathogenic Variants, Family History, and Cumulative Risk of Breast Cancer in US Women.
JAMA oncology [Epub ahead of print].
IMPORTANCE: Inherited pathogenic variants (PVs) in known predisposition genes can greatly increase breast cancer risk, but the combined impact of PV status, family history, and other factors on breast cancer risk in the general US population has not been well described.
OBJECTIVE: To evaluate population-based breast cancer risk estimates for those with established PVs overall and stratified by first-degree family history of breast cancer and other factors.
This study used pooled data from 13 US-based breast cancer case-control studies participating in the Cancer Risk Estimates Related to Susceptibility (CARRIERS) consortium. Enrollment for individual studies occurred between 1976 and 2013, and results are based on data released March 2023, with analyses conducted from June 2022 to July 2025.
EXPOSURES: PVs, breast cancer family history, self-reported race and ethnicity, and established risk factors.
MAIN OUTCOMES AND MEASURES: Breast cancer rate ratios for PVs in 7 genes were estimated from the CARRIERS consortium. PV status and incidence and mortality statistics were combined using the Individualized Coherent Absolute Risk Estimation (iCARE) model to estimate conditional cumulative breast cancer risks and 95% CIs, stratified by family history and standardized to the US population. Models that incorporated population-based data and published estimates for established epidemiologic risk factors were also evaluated.
RESULTS: A total of 67 692 women were studied, including 33 841 who were diagnosed with breast cancer. PVs in ATM, BRCA1, BRCA2, CHEK2, and PALB2 were strongly associated with breast cancer risk, with BRCA1 and PALB2 PVs showing evidence of heterogeneity by family history. In models considering PVs, family history, and established risk factors, the estimated cumulative risks of breast cancer by age 50 years ranged from 2.4% (95% CI, 2.4-2.4) in women with no PVs and no family history to 35.5% (95% CI, 21.6-55.1) in PALB2 PV carriers with a family history. Among women who have not been diagnosed with breast cancer by age 50 years, the cumulative risk of breast cancer by age 80 years ranged from 11.1% (95% CI, 11.0-11.2) in noncarriers with no family history to 70.5% (95% CI, 52.8-83.5) for PALB2 carriers with a family history. PV-specific cumulative risk estimates varied across subgroups defined by race and ethnicity and potentially modifiable epidemiologic risk factors.
CONCLUSIONS AND RELEVANCE: In this study, population-based estimates of cumulative breast cancer risk for established PVs, as informed by the CARRIERS case-control sample, varied by family history and potentially modifiable risk factors. These estimates provide guidance for identifying individuals who will most benefit from enhanced screening and prevention strategies.

Side effect management and procedural best practices with indwelling intravesical drug-releasing systems in the treatment of bladder cancer: recommendations from expert panels.
Current opinion in urology [Epub ahead of print].
PURPOSE OF REVIEW: To provide expert recommendations for side effect management in patients with bladder cancer receiving intravesical-drug releasing system (iDRS) treatment and for optimizing iDRS insertion procedure success.
RECENT FINDINGS: Indwelling iDRS are designed to provide sustained local exposure to therapy. In clinical trials, frequent side effects of iDRS treatment were lower urinary tract symptoms (LUTS) (e.g., dysuria, pollakiuria, micturition urgency), urinary tract infections (UTIs), and hematuria. These side effects are generally low grade, but if not properly managed, may lead to treatment interruptions or discontinuations. As data are limited, practical recommendations based on expert opinion for the management of common side effects and best practices for iDRS insertion procedures may improve treatment adherence and optimize outcomes in patients with bladder cancer receiving iDRS.
SUMMARY: Two separate expert panels were convened to develop recommendations for side effect management with iDRS and optimizing iDRS insertion procedure success. Stepwise treatment-specific management strategies for LUTS, UTIs, and hematuria in patients receiving iDRS treatment that are familiar to practicing urologists are presented, including considerations for continuation or discontinuation of iDRS treatment. Several advanced techniques can be considered to improve iDRS insertions based on variations in patient anatomy.

Gut microbiome and cognitive function in the Hispanic Community Health Study/Study of Latinos.
Journal of Alzheimer's disease : JAD [Epub ahead of print].
BackgroundThere is limited work on the association between the gut microbiome and Alzheimer's disease and related dementia (AD/ADRD) in Latinos.ObjectiveWe examined, within the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) cohort, the association between gut microbiome and cognitive function.MethodsWe analyzed the fecal metagenomes of 2471 HCHS/SOL participants to identify microbial taxonomic and functional features associated with global cognitive function. Omnibus (PERMANOVA) and feature-wise analyses (MaAsLin2) were conducted to identify microbiome-cognition associations, and specific microbial species and pathways (Kyoto Encyclopedia of Genes and Genomes (KEGG modules) associated with cognition.ResultsEubacterium species (E. siraeum and E. eligens), and C phoceensis, among other species were associated with better cognition. Several KEGG modules, most strongly Ornithine, Serine biosynthesis and Urea Cycle, were associated with worse cognition.ConclusionsIn a large Hispanic/Latino cohort, we identified several microbial taxa and KEGG pathways associated with cognition.

Effects of sex but not race and geographic origin on vaccine-induced HIV-specific antibody responses.
Frontiers in immunology, 16:1601865.
BACKGROUND: Sex, race and geographic location may affect vaccine-induced immune responses, yet few preventive HIV vaccine trials have systematically evaluated such effects. The main objective of this study was therefore to examine the role of these factors on vaccine-induced HIV-specific immune responses within the HVTN 204 trial. This randomized, double-blinded, placebo-controlled phase 2 trial enrolled 480 Black and Caucasian adults from Africa and the Americas, who received a trivalent DNA-HIV-1 vaccine prime followed by a rAd5 vector HIV-1 vaccine boost.
METHODS: Available serum samples from baseline and four weeks after the final vaccination boost from Black (n=85, 59% female) and Caucasian (n=49, 51% female) HVTN 204 vaccine recipients from South Africa and the United States of America were studied using an Enzyme-Linked Immunosorbent Assay to determine titers of Envelope-specific IgG1, IgG3 and IgA antibodies. Recognition of linear Envelope peptide-specific IgG responses was mapped in a randomly selected subgroup analysis using a custom-designed peptide microarray (n = 41, 49% female). Associations between vaccine-induced Envelope-specific antibody responses and sex assigned at birth (female or male), race and geographic location were then analyzed by the Mann-Whitney U test, Fisher's exact test and multivariate logistic regression.
RESULTS: Four weeks post-final vaccination boost, we observed that Envelope-specific antibody titers were significantly increased for IgG1 but reduced for IgA in females (female vs. male median titer: 900 vs. 300, p=0.030 and <100 vs. 100, p=0.007, respectively). Multivariate logistic regression confirmed that female sex increased the odds for higher Envelope-specific IgG1 and low IgA titers compared to males. In terms of antibody epitopes, the V2 region was more frequently recognized in females than males (p=0.008). Race and geographic location had no apparent influence on antibody isotype titers investigated.
CONCLUSION: Female sex was associated with higher vaccine-induced IgG Envelope-specific binding antibody titers and recognition of V2 region of HIV Envelope in HVTN 204 volunteers. No such associations were detected for race or geographic location. Understanding biological factors driving these sex-based differences may improve the design of a new generation of HIV vaccine candidates.

Trichomonas vaginalis Among Cisgender Women Taking Doxycycline Postexposure Prophylaxis.
The Journal of infectious diseases pii:8277981 [Epub ahead of print].
Doxycycline treats and prevents several bacterial and parasitic infections and has been proposed as a possible treatment for Trichomonas vaginalis. Nested in a trial of doxycycline postexposure prophylaxis among cisgender women in Kenya, we conducted a secondary analysis of incident T. vaginalis infections. Among 224 cisgender women randomized to doxycycline postexposure prophylaxis and 225 to standard-of-care, there were 27 T. vaginalis diagnoses in the doxycycline postexposure prophylaxis group and 29 in the standard-of-care group (RR: 0.96, 95% CI: 0.54-1.73, p=0.9)). Understanding doxycycline postexposure prophylaxis's impact on T. vaginalis remains an important public health question that warrants further investigation.

Heuriskance: a novel paradigm for systematic earlier detection of sporadic pancreatic cancer.
Journal of the National Cancer Institute pii:8277931 [Epub ahead of print].
Early detection is key to improving survival and mortality from pancreatic cancer. Traditional periodic screening for cancer in an asymptomatic population is infeasible and not recommended for this low-incidence disease. We describe a novel approach we call "heuriskance" (hyou-ris-kance) wherein a systematic search for and onetime workup of a "heurisk" (hyou-risk) leads to earlier detection of cancer. A heurisk is an early warning sign with three defining characteristics: i) indicates higher-than-threshold-probability of having prevalent invasive cancer, ii) is associated with a meaningful lead time to diagnosis, and iii) is identifiable by a systematic and scalable process in the population. Heuriskance aims to systematically detect cancer with clinically meaningful lead time to clinical diagnosis, minimize proportion of patients with advanced disease, and maximize treatment options leading to increases in lead time-adjusted 1-, 3- and eventually 5- year survival. A specific example of a heurisk for pancreatic cancer is glycemically defined new onset diabetes (GNOD) and the Early Detection Initiative (NCT04662879) an example of GNOD-based heuriskance. As heuriskance has no precedent, we provide i) a tiered risk stratification approach (Define-Enrich-Find), ii) metrics for choosing a heurisk, iii) success metrics for strategy and iv) Phases 1-5 for evaluating the strategy in retrospective and prospective studies. Like all current cancer therapies, heuriskance aims to iteratively improve survival from a fatal disease using a pragmatic, evidence-based systematic approach to its earlier detection. The concept of heuriskance is applied to pancreatic cancer but could be extended to other cancer types.

Multiplex serology reveals age-specific immunodynamics of endemic respiratory pathogens in the wake of the COVID-19 pandemic.
medRxiv : the preprint server for health sciences.
The rebound of endemic respiratory viruses following the COVID-19 pandemic was marked by atypical transmission dynamics, with children experiencing increased disease burden and out-of-season epidemics as restrictions relaxed. Here we used serology from a newly developed quantitative multiplex assay to assess the post-pandemic immunity debt, a drop in immunity due to a lack of endemic virus circulation during COVID-19. We assessed age-specific antibody dynamics in Seattle, Washington, US, across a broad range of respiratory viruses, including influenza, respiratory syncytial virus, seasonal coronaviruses, and SARS-CoV-2. We found that respiratory virus immunodynamics differed between individuals <5 years of age and older individuals, with young children experiencing both larger boosts and quicker waning of antibodies across pathogens. We confirmed that these patterns are upheld in a non-pandemic setting by analyzing influenza serological data from South Africa. We incorporated our serological insights into an influenza transmission model calibrated to epidemiological data from Seattle and show that consideration of age-specific immunodynamics may be important to anticipate the effects of pandemic perturbations.

Understanding cholera dynamics in African countries with persistent outbreaks: a mathematical modeling approach.
BMC public health, 25(1):3395.
BACKGROUND: Cholera, caused by Vibrio cholerae, is a global health challenge, spreading through water in areas lacking clean water and sanitation. Since 2021, the reemergence of cholera cases has increased significantly in endemic regions in Africa. In particular, the continent experienced severe outbreaks between 2022 and 2024 due to droughts and cyclones, which have placed additional strain on healthcare systems.
OBJECTIVE: This study aims to investigate the dynamics of cholera outbreaks in eight African countries using mathematical modeling and machine learning and to provide information for public health decision making. By estimating key model parameters and epidemiological indicators, such as the basic reproduction number, we aim to identify and quantify the impacts of key transmission drivers. Using this together to socioeconomical factors, we will be classifying cholera persistent countries with similar dynamics using unsupervised learning. In addition, the study seeks to provide information on cholera outbreaks and management across the selected countries, identify key drivers of outbreak intensity, and propose targeted intervention strategies.
METHODS: A compartmentalized epidemiological model with indirect transmission routes is analyzed for cholera dynamics in eight African countries with persistent outbreaks. The key parameters and initial values of the model's variables were estimated using a Bayesian framework. We assessed some outcomes such as the reproduction number, "[Formula: see text]," outbreak peak duration and size. Moreover, environmental and socioeconomic data were used in hierarchical clustering to group countries by outbreak characteristics.
RESULTS: The study uncovered variation in cholera outbreak dynamics across the considered countries. Based on our model results, the median basic reproduction number ([Formula: see text]) across the endemic countries was 2.0 (SD : 0.454), which ranges from 1.41 in Zimbabwe to 2.80 in Mozambique. Furthermore, the results of the sensitivity analysis emphasized the significance of the maximum infection rate and the bacteria shedding rate in driving cholera outbreaks across the endemic regions in Africa. Hierarchical clustering revealed three distinct groups of countries based on outbreak dynamics and socioeconomic indicators: the chronic sanitation issues cluster (Somalia, Cameroon, and Comoros); the economic and infrastructure challenges cluster (Sudan, Zimbabwe, and Zambia); and the natural disaster cluster (Malawi and Mozambique).
CONCLUSION: This study highlights the drivers of cholera outbreaks across African countries, emphasizing the need for tailored interventions that consider underlying socio-demographic and environmental vulnerabilities. The findings underscore the importance of integrating data-driven approaches into cholera preparedness and response efforts to mitigate its impact.

Utility of quantitative pathologic analysis of pT1 colorectal carcinomas to improve prediction of lymph node metastasis.
Virchows Archiv : an international journal of pathology [Epub ahead of print].
According to the National Comprehensive Cancer Network (NCCN), submucosally invasive (pT1) colorectal carcinomas (CRCs) should be evaluated for tumor grade, lymphatic invasion, and tumor budding to determine the risk of lymph node metastasis. The presence of any one of these high-risk features is an indication for surgery in endoscopically removed pT1 CRCs. In this study, we determined if quantitative pathologic analysis with the QuantCRC algorithm can augment NCCN risk stratification in a multi-institutional cohort of 512 surgically resected pT1 CRC. LASSO regression identified %high-grade, %inflammatory stroma (stromal area), and %tumor budding/poorly differentiated clusters (%TB/PDC) as important QuantCRC features and were used in subsequent logistic regression analysis. Five logistic regression models were built using NCCN and QuantCRC variables, with the combined NCCN + QuantCRC model providing the highest Area Under the Curve (AUC) of 0.74 (95% CI 0.68-0.81). A predicted probability cutoff of 0.092 provided a sensitivity of 78.3% and specificity of 62.1% in the NCCN + QuantCRC model with a 24.3% rate of lymph node positivity for high-risk (HR) tumors compared to 5.2% for low-risk (LR) CRCs. Fifteen pT1 CRCs were reclassified from NCCN LR to NCCN + QuantCRC HR and 3/15 (20%) demonstrated lymph node positivity. The median predicted probability of lymph node metastasis in the NCCN + QuantCRC model was used to define two HR groups (HR1: 0.092-0.218 and HR2: > 0.218). HR2 CRCs had a rate of lymph node positivity of 31.5% compared to 17.1% for HR1 CRCs (P = 0.02). Lastly, the NCCN + QuantCRC model was validated in a cohort of 29 endoscopically resected pT1 CRCs followed by surgical resection. In the NCCN + QuantCRC model, the 8 pN + CRCs in this cohort had a higher median predicted probability of lymph node metastasis compared to 21 pN0 CRCs (0.219 vs. 0.080, P = 0.04). In summary, the addition of variables from QuantCRC can improve risk stratification of pT1 CRCs over NCCN criteria alone.

Elucidating molecularly stratified single agent, and combination, therapeutic strategies targeting MCL1 for lethal prostate cancer.
Nature communications, 16(1):8806.
Metastatic castration-resistant prostate cancer (mCRPC) is a lethal disease requiring additional therapeutic strategies. MCL1, an anti-apoptotic BCL2 family member, promotes cancer-cell survival, but its role in mCRPC remains poorly understood. Here, we characterise MCL1 in multiple mCRPC biopsy cohorts and patient-derived models, assessing responses to MCL1 inhibition. MCL1 copy number gain (14%-34%) correlates with increased MCL1 expression and worse outcomes. MCL1 inhibition exhibits anti-tumour effects in MCL1-gained mCRPC models. Co-inhibition of MCL1 and AKT induces cancer-specific cell death in PTEN-loss/PI3K-activated models in vitro and in vivo, modulating BAD-BCLXL and BIM-MCL1 interactions, with durable anti-tumour activity in models with AKT inhibitor acquired resistance. Finally, CDK9-mediated MCL1 downregulation combined with AKT inhibition recapitulates these findings, providing further opportunities for clinical translation. These data support early phase clinical trials targeting MCL1, both as monotherapy for MCL1-gained mCRPC, and in combination with AKT inhibition for PTEN-loss/PI3K-activated mCRPC.

abstract = {Metastatic castration-resistant prostate cancer (mCRPC) is a lethal disease requiring additional therapeutic strategies. MCL1, an anti-apoptotic BCL2 family member, promotes cancer-cell survival, but its role in mCRPC remains poorly understood. Here, we characterise MCL1 in multiple mCRPC biopsy cohorts and patient-derived models, assessing responses to MCL1 inhibition. MCL1 copy number gain (14%-34%) correlates with increased MCL1 expression and worse outcomes. MCL1 inhibition exhibits anti-tumour effects in MCL1-gained mCRPC models. Co-inhibition of MCL1 and AKT induces cancer-specific cell death in PTEN-loss/PI3K-activated models in vitro and in vivo, modulating BAD-BCLXL and BIM-MCL1 interactions, with durable anti-tumour activity in models with AKT inhibitor acquired resistance. Finally, CDK9-mediated MCL1 downregulation combined with AKT inhibition recapitulates these findings, providing further opportunities for clinical translation. These data support early phase clinical trials targeting MCL1, both as monotherapy for MCL1-gained mCRPC, and in combination with AKT inhibition for PTEN-loss/PI3K-activated mCRPC.},

Combined crystallographic fragment screening and deep mutational scanning enable discovery of Zika virus NS2B-NS3 protease inhibitors.
Nature communications, 16(1):8930.
The Zika viral protease NS2B-NS3 is essential for the cleavage of viral polyprotein precursor into individual structural and non-structural (NS) proteins and is therefore an attractive drug target. Generation of a robust crystal system of co-expressed NS2B-NS3 protease has enabled us to perform a crystallographic fragment screening campaign with 1076 fragments. 46 fragments with diverse scaffolds are identified to bind in the active site of the protease, with another 6 fragments observed in a potential allosteric site. To identify binding sites that are intolerant to mutation and thus suppress the outgrowth of viruses resistant to inhibitors developed from bound fragments, we perform deep mutational scanning of the NS2B-NS3 protease. Merging fragment hits yields an extensive set of 'mergers', defined as synthetically accessible compounds that recapitulate constellations of observed fragment-protein interactions. In addition, the highly sociable fragment hits enable rapid exploration of chemical space via algorithmic calculation and thus yield diverse possible starting points. In this work, we maximally explore the binding opportunities to NS2B-NS3 protease, facilitating its resistance-resilient antiviral development.

Randomized Trial of Targeted Indoor Spraying to Prevent Aedes-Borne Diseases.
The New England journal of medicine, 393(14):1387-1398.
BACKGROUND: Targeted indoor residual spraying focuses insecticide applications on common resting surfaces of Aedes aegypti mosquitoes (an arboviral disease vector) in houses, such as exposed lower sections of walls and under furniture.
METHODS: We conducted a two-group, parallel, unblinded, cluster-randomized trial in Merida, Mexico, to quantify the efficacy of targeted indoor residual spraying for preventing aedes-borne diseases (chikungunya, dengue, or Zika). Children 2 to 15 years of age were enrolled from households in 50 clusters of five-by-five city blocks. Households in 25 clusters received an annual application of targeted indoor residual spraying (intervention) before each season of aedes-borne disease (July through December). All clusters received routine Ministry of Health vector control. The primary end point was laboratory-confirmed, symptomatic aedes-borne disease. Community effects were assessed with the use of geolocated national surveillance data.
RESULTS: A total of 4461 children were monitored for up to three seasons (2021, 2022, and 2023). The indoor density of A. aegypti mosquitoes was 59% (95% confidence interval [CI], 51 to 65) lower with the intervention than with control. A total of 422 cases of aedes-borne disease were confirmed, primarily dengue in 2023. In the per-protocol analysis of cluster centers, 91 cases occurred among 1038 participants in the intervention group and 89 cases among 1037 participants in the control group (efficacy, -12.8%; 95% CI, -60.7 to 23.0). In an intention-to-treat analysis of entire clusters, 198 cases occurred among 2239 participants in the intervention group and 199 cases among 2222 participants in the control group (efficacy, 3.9%; 95% CI, -28.1 to 26.7). Adjustment of analyses for mobility or demographic characteristics did not change results. On the basis of 150 cases in the intervention clusters and 202 in the control clusters that were geolocated, the estimated community effect of the intervention was 24.0% (95% CI, 6.0 to 38.6). Two cases of multisymptom adverse events (e.g., nausea, watery eyes, diarrhea, and vomiting) were associated with the intervention.
CONCLUSIONS: Despite lower entomologic indexes with targeted indoor residual spraying than with routine vector control, the cumulative incidence of aedes-borne diseases was not significantly lower with targeted indoor residual spraying.

Injury-Induced Connexin 43 Expression Regulates Endothelial Wound Healing.
American journal of physiology. Heart and circulatory physiology [Epub ahead of print].
Endothelial cell (EC) injury is a major contributing factor to vascular surgical failure. As such, understanding the mechanisms of endothelial healing is essential to the development of vascular therapeutics and procedures. Gap junctions formed by connexin 43 (Cx43) are implicated in regulating skin wound healing, but their role in endothelial healing is unknown. Secondary analysis of RNAseq data from in vivo injured mouse aortas (GEO: GSE115618), identified significant Cx43 upregulation in EC post-injury. We developed a novel in vivo model of EC injury using mouse carotid artery ligation to test the role of Cx43. We identified that EC immediately adjacent to the wound edge upregulate Cx43 protein expression, predominantly at cell-cell junctions. We show significantly delayed EC healing in a mouse model of inducible EC-specific Cx43 deletion (EC-Cx43 KO) at 24 hr post ligation. Single cell RNAseq analysis of 10,829 cells from 18 hr injured EC-WT and EC-Cx43 KO carotids revealed a Cx43-associated reduction in enrichment of EC pathways associated with migration, proliferation, and ERK/MAPK signaling pathways. Finally, the importance of Cx43 phosphorylation on EC healing was tested in mice with single-point alanine mutations (phospho-null) in known phosphorylation sites that alter Cx43 channel assembly and opening. Mice containing alanine mutations at ERK phosphorylated Cx43 serines (Cx43[S255/262/279/282A]) have reduced healing rates similar to EC-Cx43 KO mice. These data suggest that EC injury-induced Cx43 upregulation, and subsequent Cx43 gap junction-mediated cell-to-cell communication are required for normal EC migration during wound healing after vascular injury.

Taxonomy Portraits: Deciphering the Hierarchical Relationships of Medical Large Language Models.
JMIR medical informatics, 13:e72918.
BACKGROUND: Large language models (LLMs) continue to enjoy enterprise-wide adoption in health care while evolving in number, size, complexity, cost, and most importantly performance. Performance benchmarks play a critical role in their ranking across community leaderboards and subsequent adoption.
OBJECTIVE: Given the small operating margins of health care organizations and growing interest in LLMs and conversational artificial intelligence (AI), there is an urgent need for objective approaches that can assist in identifying viable LLMs without compromising their performance. The objective of the present study is to generate taxonomy portraits of medical LLMs (n=33) whose domain-specific and domain non-specific multivariate performance benchmarks were available from Open-Medical LLM and Open LLM leaderboards on Hugging Face.
METHODS: Hierarchical clustering of multivariate performance benchmarks is used to generate taxonomy portraits revealing inherent partitioning of the medical LLMs across diverse tasks. While domain-specific taxonomy is generated using nine performance benchmarks related to medicine from the Hugging Face Open-Medical LLM initiative, domain non-specific taxonomy is presented in tandem to assess their performance on a set of six benchmarks and generic tasks from the Hugging Face Open LLM initiative. Subsequently, non-parametric Wilcoxon rank-sum test and linear correlation are used to assess differential changes in the performance benchmarks between two broad groups of LLMs and potential redundancies between the benchmarks.
RESULTS: Two broad families of LLMs with statistically significant differences (α=.05) in performance benchmarks are identified for each of the taxonomies. Consensus in their performance on the domain-specific and domain non-specific tasks revealed robustness of these LLMs across diverse tasks. Subsequently, statistically significant correlations between performance benchmarks revealed redundancies, indicating that a subset of these benchmarks may be sufficient in assessing the domain-specific performance of medical LLMs.
CONCLUSIONS: Understanding medical LLM taxonomies is an important step in identifying LLMs with similar performance while aligning with the needs, economics, and other demands of health care organizations. While the focus of the present study is on a subset of medical LLMs from the Hugging Face initiative, enhanced transparency of performance benchmarks and economics across a larger family of medical LLMs is needed to generate more comprehensive taxonomy portraits for accelerating their strategic and equitable adoption in health care.

AAPM CT metal artifact reduction grand challenge.
Medical physics, 52(10):e70050.
BACKGROUND: Metal artifact reduction (MAR) is a long-standing challenge in CT imaging. The presence of highly attenuating objects, such as dental fillings, hip prostheses, spinal screws/rods, and gold fiducial markers, can introduce severe streak artifacts in CT images, often reducing their diagnostic value. Existing CT MAR studies typically define their own test cases and evaluation metrics, making it difficult to objectively and comprehensively compare the performance of different MAR methods. There is a widespread need for a universal CT MAR image quality benchmark to evaluate the clinical impact of new MAR methods and compare them to state-of-the-art techniques.
PURPOSE: The goal of the AAPM CT Metal Artifact Reduction (CT-MAR) grand challenge was to create and distribute a clinically representative 2D MAR performance benchmark, and to invite participants to objectively compare the performance of their MAR methods based on this benchmark. A secondary goal was to facilitate MAR development by disseminating a MAR training database and tools. After completion of the grand challenge, the MAR benchmark and the MAR training database will remain publicly accessible for future MAR developments and benchmarking.
METHODS: Grand challenge participants were invited to submit results for their MAR algorithm. The challenge organizers provided 14,000 CT training datasets generated using a hybrid data simulation framework that combined real patient images-including lung, abdomen, liver, head, and pelvis-with virtual metal objects. Each training dataset included five types of data: CT sinograms (uncorrected and metal-free), CT reconstructed images (uncorrected and metal-free), and metal masks. In the final evaluation phase, 29 clinical uncorrected datasets with metal were provided in both the sinogram and image domains for participants to process with their MAR algorithms. Their results were evaluated using eight clinically relevant image quality metrics. The final ranking was determined and compared to an established normalized metal artifact reduction (NMAR) reference method. Additionally, we conducted a survey to better understand the methodologies used by participants.
RESULTS: A total of 106 teams registered for the challenge, with 26 teams completing all phases of the challenge. 92% of these-including all top ten teams-used a deep learning (DL) approach, employing a variety of network architectures such as UNet, ResNet, GAN, diffusion models, and transformers. Additionally, 22% of the teams-including the top three teams-utilized a combination of sinogram- and image-domain approaches. The results showed a broad distribution of the scores. Overall, the competition was marked by diverse methods and a wide range of results, including some truly exceptional results. More than 70% of the teams achieved a better overall score than the popular baseline NMAR method.
CONCLUSIONS: The CT-MAR grand challenge provided an opportunity to benchmark state-of-the-art MAR algorithms. Our hybrid data generation framework was a powerful tool for simulating large-scale realistic datasets for MAR algorithm development.

abstract = {BACKGROUND: Metal artifact reduction (MAR) is a long-standing challenge in CT imaging. The presence of highly attenuating objects, such as dental fillings, hip prostheses, spinal screws/rods, and gold fiducial markers, can introduce severe streak artifacts in CT images, often reducing their diagnostic value. Existing CT MAR studies typically define their own test cases and evaluation metrics, making it difficult to objectively and comprehensively compare the performance of different MAR methods. There is a widespread need for a universal CT MAR image quality benchmark to evaluate the clinical impact of new MAR methods and compare them to state-of-the-art techniques.
PURPOSE: The goal of the AAPM CT Metal Artifact Reduction (CT-MAR) grand challenge was to create and distribute a clinically representative 2D MAR performance benchmark, and to invite participants to objectively compare the performance of their MAR methods based on this benchmark. A secondary goal was to facilitate MAR development by disseminating a MAR training database and tools. After completion of the grand challenge, the MAR benchmark and the MAR training database will remain publicly accessible for future MAR developments and benchmarking.
METHODS: Grand challenge participants were invited to submit results for their MAR algorithm. The challenge organizers provided 14,000 CT training datasets generated using a hybrid data simulation framework that combined real patient images-including lung, abdomen, liver, head, and pelvis-with virtual metal objects. Each training dataset included five types of data: CT sinograms (uncorrected and metal-free), CT reconstructed images (uncorrected and metal-free), and metal masks. In the final evaluation phase, 29 clinical uncorrected datasets with metal were provided in both the sinogram and image domains for participants to process with their MAR algorithms. Their results were evaluated using eight clinically relevant image quality metrics. The final ranking was determined and compared to an established normalized metal artifact reduction (NMAR) reference method. Additionally, we conducted a survey to better understand the methodologies used by participants.
RESULTS: A total of 106 teams registered for the challenge, with 26 teams completing all phases of the challenge. 92% of these-including all top ten teams-used a deep learning (DL) approach, employing a variety of network architectures such as UNet, ResNet, GAN, diffusion models, and transformers. Additionally, 22% of the teams-including the top three teams-utilized a combination of sinogram- and image-domain approaches. The results showed a broad distribution of the scores. Overall, the competition was marked by diverse methods and a wide range of results, including some truly exceptional results. More than 70% of the teams achieved a better overall score than the popular baseline NMAR method.
CONCLUSIONS: The CT-MAR grand challenge provided an opportunity to benchmark state-of-the-art MAR algorithms. Our hybrid data generation framework was a powerful tool for simulating large-scale realistic datasets for MAR algorithm development. A clinically relevant universal MAR benchmark offered an objective and meaningful way to compare different approaches. The training data and benchmark were published online to support future MAR development.},

A hybrid training database and evaluation benchmark for assessing metal artifact reduction methods for X-ray CT imaging.
Medical physics, 52(10):e70020.
BACKGROUND: Metal artifacts significantly degrade the image quality in computed tomography (CT) imaging, obscuring or even feigning pathology. While many different algorithms for metal artifact reduction (MAR) have been proposed, no comprehensive, clinically relevant evaluation benchmark exists. A major contributing factor to this is the lack of artifact-free ground truth data in clinical cases. Similarly, deep-learning based algorithms are hindered by the lack of paired training datasets with and without artifacts.
PURPOSE: We propose the simulation of a large training database for deep-learning based MAR algorithms as well as the definition of a comprehensive evaluation benchmark for MAR. For this we utilize and validate a framework for the realistic simulation of metal artifacts on clinical CT data.
METHODS: A clinical and a generic CT scanner geometry is modelled in the CatSim CT simulator within the open-access toolkit XCIST. Since most MAR research is performed in 2D, all datasets are simulated in 2D. The metal artifact simulation capability is experimentally validated in CT phantom scans containing various metal types and -geometries. The tool is then used to simulate metal artifact scenarios as training data for deep-learning algorithms utilizing two public CT databases. Lastly, a benchmark is defined for clinically realistic metal artifact scenarios and applied to a numerical and a deep-learning based MAR algorithm, respectively.
RESULTS: Within specified regions of interest, the mean CT number deviation between simulation and real data was less than 2%, making the simulation tool suitable for the aspired tasks. In total, 14,000 metal scenarios in the head, thorax and pelvis regions were simulated. For the clinical benchmark, a set of metrics covering CT number accuracy, noise, image sharpness, streak amplitude, structural integrity, and the effect on range in proton therapy, were defined for a range of clinical scenarios. Metal scenarios covered the most relevant clinical use cases, covering small metal implants such as fiducial markers up to large metal implants such as hip replacements. Both the simulation tools and the benchmark with the test cases were made publicly available.
CONCLUSIONS: We developed and distributed tools and datasets for the development and evaluation of MAR algorithms. This is the first comprehensive evaluation benchmark covering a large number of clinically realistic metal artifact scenarios.

Niraparib and abiraterone acetate plus prednisone for HRR-deficient metastatic castration-sensitive prostate cancer: a randomized phase 3 trial.
Nature medicine [Epub ahead of print].
Inhibition of poly(ADP-ribose) polymerase (PARP) after relapse on hormone therapy is well established for patients with prostate cancer with homologous recombination repair (HRR) gene alterations, but resistance often develops. We hypothesized that PARP inhibition within 6 months of starting androgen deprivation therapy for metastatic castration-sensitive prostate cancer (mCSPC) could be effective and improve radiographic progression-free survival when added to standard-of-care treatments. The double-blind AMPLITUDE trial evaluated combining niraparib, a potent and specific PARP inhibitor, with abiraterone acetate and prednisone (AAP) versus placebo and AAP in mCSPC with HRR gene alterations. Patients (n = 696) were randomized in a 1:1 ratio (348 per group). Median age was 68 years; 56% had BRCA1 or BRCA2 alterations; 78% had high-volume metastases; and 16% had received docetaxel. The primary endpoint was met, with a significant improvement in radiographic progression-free survival observed first in the BRCA subgroup (median not reached at the time of analysis for the niraparib and AAP group versus 26 months for the AAP group; hazard ratio = 0.52; 95% confidence interval: 0.37-0.72; P < 0.0001) and then in the intention-to-treat population (hazard ratio = 0.63; 95% confidence interval: 0.49-0.80; P = 0.0001). The data for overall survival, a key secondary endpoint, are immature (193/389 events) but favor niraparib (hazard ratio = 0.79 (95% confidence interval: 0.59-1.04); BRCA subgroup: hazard ratio = 0.75 (95% confidence interval: 0.51-1.11)). Incidence of grade 3 or 4 adverse events was 75% in the niraparib and AAP group and 59% in the AAP group; most frequent in the niraparib and AAP group were anemia (29%), with 25% of patients requiring a blood transfusion, and hypertension (27%). There were 14 treatment-emergent adverse events leading to deaths in the niraparib group and seven in the placebo group. Combining niraparib with AAP significantly improved radiographic progression-free survival in patients with mCSPC harboring BRCA1/BRCA2 or other HRR gene alterations, suggesting clinical benefit with this combination for these patients.

Racial and ethnic differences in valuation of life expectancy in prostate cancer treatment decision making.
Prostate cancer and prostatic diseases [Epub ahead of print].
BACKGROUND: Life expectancy (LE) is essential for triage between aggressive and conservative management for all prostate cancer risk subtypes. We sought to investigate differences in how Black and Hispanic men interpret LE in treatment decision-making.
METHODS: We used targeted crowdsourcing to sample a cohort reflecting sociodemographics of a US prostate cancer population. Subjects completed a conjoint analysis exercise where they iteratively chose between aggressive treatment versus conservative management across levels of 4 tradeoffs-tumor risk (lives saved by aggressive treatment at 5/10/20 year); erectile dysfunction; urinary incontinence; and irritative urinary symptoms-while considering their LE as calculated by the Prostate Cancer Comorbidity Index. Multinomial conditional logistic regression compared odds of choosing aggressive vs. conservative treatment across LEs ranging from 0 to 20 years overall and across racial/ethnic subgroups.
RESULTS: Of 2046 men, 435 (22%) were Black and 230 (11%) were Hispanic. Across all men, the odds of aggressive treatment choice increased by 17% for every 5 years of additional LE (OR = 1.17, 95%CI = 1.12-1.22, p < 0.001). Men were significantly more likely to choose aggressive treatment at LE > 13 y and non-aggressive treatment at LE ≤ 10 y. Among Black men, LE was not associated with treatment choice, as they consistently preferred aggressive treatment across all LE categories. Among Hispanic men, increased LE was associated with a higher likelihood of choosing aggressive treatment, with significant preference for aggressive treatment observed only when LE > 10 years. These patterns remained consistent when further stratified by tumor risk.
CONCLUSIONS: LE had no impact on treatment decisions in Black men, in contrast to other races and ethnicities. Future research is needed to identify reasons for this phenomenon and to inform culturally relevant approaches to communicating competing mortality risks.

Safety and immunogenicity of investigational herpes simplex virus-2 vaccines in adults with recurrent genital infection.
Vaccine, 65:127821 pii:S0264-410X(25)01118-1 [Epub ahead of print].
HSV529 and G103 are investigational therapeutic vaccines for genital herpes. HSV529 is a replication-defective HSV-2. G103 contains three recombinant HSV-2 proteins: truncated UL19 and gD2 and full-length UL25. A randomized, placebo-controlled clinical trial was conducted over a two-dose schedule to assess various combinations of G103 and HSV529 with GLA-SE adjuvant in 24 participants. No immediate unsolicited adverse reactions were observed. Most injection site reactions (>50 %) were grade 2 with one reported grade 3 swelling. Grade 2 systemic reactions (headache and myalgia) were independent of GLA-SE dose. The vaccine candidates showed adequate safety profiles. All participants had baseline immune responses to HSV-2. gD2, UL19, and UL25-specific CD4 T cells increased in G103 recipients after the first dose and were most robust for gD2. Binding antibody levels increased most markedly for UL25, as did neutralizing antibodies.

ESP Quick Facts
ESP Origins
In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.
ESP Support
In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.
ESP Rationale
Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.
ESP Goal
In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.
ESP Usage
Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.
ESP Content
When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.
ESP Help
Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.
ESP Plans
With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.
