First successful case of platinum‐based chemotherapy for neuroendocrine prostate cancer with BRCA2 and PTEN alterations

Introduction Deoxyribonucleic acid repair gene mutations are now being studied in a variety of solid tumors, with the hope of predicting prognosis, pathogenesis, and treatment outcomes. Case presentation We report the case of a Japanese patient with advanced castration‐resistant prostate cancer who exhibited a prominent response to platinum therapy and had coexisting BRCA2 and PTEN mutations according to retrospective multigene panel analysis. Conclusion Through a review of clinical outcomes and genetic/pathologic profiling, the presented case provides insights into future management strategies based on the tumor genetic status.
