Abstract

Metastatic prostate cancer (mPC) is enriched for homologous recombination repair (HRR) gene alterations, which have prognostic and predictive value. Routine clinical implementation of next-generation sequencing (NGS) is still limited. We investigated the association between genomic and functional loss of HRR, using NGS and RAD51 immunofluorescence (RAD51-IF) in 219 primary or metastatic biopsies from 187 patients with stage IV prostate cancer. NGS showed frequent genomic alterations in TP53 (40%), AR (15%), PTEN (14%), FOXA1 (12%), MYC (10%), BRCA2 (9%), ATM (8%), and BRCA1 (2%). We pursued RAD51-IF in 206 samples; of those, 139/206 (67%) were evaluable. 21% of samples had RAD51-low score compatible with HRR deficiency (HRD). RAD51-IF showed high sensitivity (71%) and specificity (86%) for BRCA1/2 alterations. Patients with RAD51-low scores experienced longer progression-free survival (PFS) on poly(ADP-ribose) polymerase inhibitors (PARPi) or platinum chemotherapy. RAD51-IF is feasible in routine clinical samples from patients with mPC and is associated with clinically relevant HRR gene alterations.

期刊介绍： Cell Reports Medicine is an esteemed open-access journal by Cell Press that publishes groundbreaking research in translational and clinical biomedical sciences, influencing human health and medicine. Our journal ensures wide visibility and accessibility, reaching scientists and clinicians across various medical disciplines. We publish original research that spans from intriguing human biology concepts to all aspects of clinical work. We encourage submissions that introduce innovative ideas, forging new paths in clinical research and practice. We also welcome studies that provide vital information, enhancing our understanding of current standards of care in diagnosis, treatment, and prognosis. This encompasses translational studies, clinical trials (including long-term follow-ups), genomics, biomarker discovery, and technological advancements that contribute to diagnostics, treatment, and healthcare. Additionally, studies based on vertebrate model organisms are within the scope of the journal, as long as they directly relate to human health and disease.
