- Real-World HRR Testing Pathways and Patterns of Detected Alterations in Prostate Cancer From the Multinational ARON-3 Study. [Journal Article]Prostate. 2026 Oct 12. [Online ahead of print]P
- CONCLUSIONS: This multinational real-world analysis demonstrates substantial heterogeneity in HRR testing uptake and testing pathways across participating ARON-3 centres. Testing was more commonly performed in patients with more advanced disease features, suggesting that clinically relevant subgroups may still be differentially selected for genomic assessment. Broader and more standardised implementation of comprehensive HRR profiling may improve the identification of actionable alterations and strengthen precision medicine in prostate cancer.

- Circulating Tumor Cell Synaptophysin and Androgen Receptor Expression Reflect Prostate Cancer Phenotypes in Metastatic Disease. [Journal Article]Prostate. 2026 Oct 11. [Online ahead of print]P
- CONCLUSIONS: SYP and AR CTC expression showed strong concordance with tissue histology and clinical features of NE differentiation and AR-positive adenocarcinoma. These findings support the feasibility of CTC immunophenotyping to characterize lineage-associated phenotypes including SYP-expressing NE differentiation in mCRPC. Prospective validation in larger cohorts with matched tissue biopsies is needed to define the clinical utility of this approach.

- Exploratory Analysis of Peri-Prostatic Adipose Tissue Radiomics Features and Their Potential to Predict Prostate Cancer Diagnosis: Results From a UK Biobank Study. [Journal Article]Prostate. 2026 Oct 08. [Online ahead of print]P
- CONCLUSIONS: An automated process for data curation and image segmentation was successfully demonstrated. Results suggest that Ant PPAT justifies further investigation as a predictive biomarker for prostate cancer diagnosis.

- CONCLUSIONS: In the secondary analysis of SWOG 1216, TTM was not independently associated with survival outcomes in the multivariable analysis. These findings suggest that TTM alone may not provide sufficient prognostic information to guide patient counseling, and treatment decisions after metastatic recurrence.

- Stage-Specific Racial Disparities in Prostate Cancer Survival Outcomes. [Journal Article]Prostate. 2026 Oct 06. [Online ahead of print]P
- CONCLUSIONS: Disparate survival outcomes for AA men with PCa emerge mainly at Stage 3 or 4 diagnosis, emphasizing the importance of early detection for these men. Notably, AA patients with advanced-stage disease were more likely to receive hormone therapy alone, a treatment pattern that may contribute to racial disparities in PCa survival.

- Human Prostate Cell Lines: Derivation, Molecular Characteristics and Appropriate Use. [Review]Prostate. 2026 Oct 06. [Online ahead of print]P
- CONCLUSIONS: Several descriptions repeated in the secondary literature are not supported by the primary characterization of the lines concerned. Selection of a line from the research question rather than from availability, verification of the relevant target in the working stock, authentication by short tandem repeat profiling, and full reporting of passage number and culture conditions would remove a substantial part of the variability presently seen in this literature.

- Urinary Soluble Collagen Levels Are Associated With Moderate/Severe LUTS. [Journal Article]Prostate. 2026 Oct 06. [Online ahead of print]P
- CONCLUSIONS: Urinary soluble collagen levels increase concurrently with moderate/severe LUTS, and are stable in urine after long-term storage at -80°C. These findings suggest that urinary soluble collagen levels may serve as suitable diagnostic biomarkers for prostatic collagenization consistent with fibrosis in association with LUTS. Potentially, urinary soluble collagen levels may be used as surrogate endpoint biomarkers to assess the efficacy of anti-fibrotic medical or surgical therapies to decrease prostatic urethral obstruction or resistance, and alleviate LUTS.

- CONCLUSIONS: In advanced, therapy-resistant prostate cancer, BRCA deleterious alterations were more frequent in younger patients and those in with a family history of breast and ovarian cancer. BRCA2 HD was significantly associated with a favorable response to olaparib.

- NCCN Risk Groups Do Not Predict Adverse Pathology or Oncologic Outcomes Among Patients With Grade Group 1 Prostate Cancer in the MRI Era. [Journal Article]Prostate. 2026 Sep 27. [Online ahead of print]P
- CONCLUSIONS: Prior to prostate MRI, NCCN risk groups offered meaningful prognostication among patients with GG1 PCa. However, the utility of NCCN risk groups for GG1 in the MRI era appears limited. Contemporary risk stratification for GG1 should focus on biopsy and MRI characteristics rather than NCCN criteria.

- Is a Few Too Many? Alcohol Consumption and Prostate Cancer Upgrading During Active Surveillance. [Journal Article]Prostate. 2026 Sep 27. [Online ahead of print]P
- CONCLUSIONS: In a large prospective cohort of men undergoing AS, higher baseline self-reported alcohol consumption was associated with upgrading to ≥ GG2 on surveillance biopsy. No association was observed with extreme upgrading. These findings may inform clinical counseling regarding alcohol use during AS, although further studies are needed to validate our findings.

- Androgen Receptor-Immune Crosstalk in Metastatic Castration-Resistant Prostate Cancer: From Context-Dependent Remodeling to Biomarker-Guided Translation. [Review]Prostate. 2026 Sep 27. [Online ahead of print]P
- CONCLUSIONS: Progress requires trials that define the relevant tumor-immune state, match treatment to the dominant resistance mechanism, and prospectively test biomarker-treatment interaction. In current practice, dMMR/MSI-H remains the only validated enrichment factor for checkpoint blockade in mCRPC; all other proposed markers and T-cell engager strategies require prospective validation of treatment interaction.

- CONCLUSIONS: Genes enriched in prostate tissue differ from those in urine. Future studies on urine biomarkers could focus on the transcripts derived from prostate epithelial cells, vascular endothelial cells, and immune cells, given their enrichment in urine.

- Cross-Cohort Characterization of an LHB-Associated Transcriptomic State in Prostate Cancer. [Journal Article]Prostate. 2026 Sep 19. [Online ahead of print]P
- CONCLUSIONS: The LHB-correlation-derived signature identifies an AR-low, proliferative, mesenchymal-associated expression state across datasets. It does not measure circulating hormones, establish LHB-dependent biology, or support clinical use. Paired molecular and functional studies are required.
