Abstract | PURPOSE: Radical prostatectomy (RP) is relatively better oncological outcomes in patients with prostate cancer (PCa). However, the incidence of castration-resistant PCa (CRPC) and PCa-specific mortality in patients with biochemical recurrence (BCR) after RP remains unclear. The aim of this study was to evaluate the cancer-specific survival (CSS) in patients with CRPC after RP, in particular those who had metastases or not. METHODS: We retrospectively reviewed the data of 1582 consecutive patients who underwent RP between July 1996 and January 2019. The enrolled patients had histologically confirmed stage T1a-T3b PCa without lymph node involvement or distant metastasis. The endpoints were oncological outcomes, including CSS and BCR, in patients with PCa with or without metastases at the time of diagnosis with CRPC. RESULTS: A total of 1474 patients were enrolled in this study. By the end of the follow-up period, 352 patients (24.6%) in the enrolled patients had BCR after RP. A total of 42 patients (2.9%) developed CRPC and 18 (1.3%) had died of PCa. With regard to metastasis in patients who diagnosed CRPC, the 5-year CSS rate was 100% for nonmetastatic CRPC (nmCRPC) patients and 53.8% for metastatic CRPC (mCRPC) patients after RP. The 5-year CSS rate was 100% for nmCRPC patients and 27.1% for mCRPC patients after the diagnosis with CRPC. CONCLUSIONS: CRPC is one of the lethal causes with PCa death. However, nmCRPC may achieve relatively good prognosis in patients with PCa after RP.
