Abstract Objective This study aimed to reveal the prognostic values of prior local therapy in first-line therapy using androgen receptor-axis targeting agents (abiraterone or enzalutamide) or docetaxel for castration-resistant prostate cancer (CRPC). Methods The study included 303 patients treated with first-line therapy for non-metastatic and metastatic CRPC. The association between prior local therapy and therapeutic outcome including progression-free survival and overall survival was investigated by univariate and multivariate analyses as well as propensity score-matched analysis. Results In univariate analysis, local prior therapy was associated with a lower risk of all-cause mortality (hazard ratio, 0.56, 95% confidence interval, 0.40–0.79; P = 0.0009). Overall survival, but not progression-free survival, was better among patients with prior local therapy compared with patients without prior local therapy even after multivariate analysis and propensity score-matched analysis. Conclusions This study robustly indicated that prior local treatment was prognostic for overall survival among patients with CRPC. This finding is useful to predict patient prognosis in CRPC.

Abstract BackgroundTo explore whether patients with distinct intraductal carcinoma of the prostate (IDC-P) subtypes respond differently to standard first-line therapy among patients with metastatic castration resistant prostate cancer (mCRPC).MethodsWe retrospectively analyzed data of 170 mCRPC patients receiving abiraterone (ABI) or docetaxel (DOC) as first-line therapy between 2014 and 2019. PSA response, PSA progression-free survival (PSA-PFS), radiographic progression-free survival (rPFS), and overall survival (OS) were analyzed and compared based on the presence of IDC-P and its sub-patterns.ResultsTotally, IDC-P was confirmed in 91/170 (53.5%) patients. Among them, 36/91 (39.6%) and 55/91 (60.4%) harbored IDC-P pattern 1 and pattern 2, respectively. The presence of IDC-P was confirmed to be associated with poor prognosis in the whole cohort. Patients with IDC-P pattern 1 shared similar clinical outcomes to those without IDC-P in both ABI and DOC treatment. However, compared to patients with IDC-P pattern 1 and without IDC-P, IDC-P pattern 2 had markedly poorer prognosis in either ABI (PSA-PFS: P<0.001; rPFS: P<0.001) or DOC (PSA-PFS: P<0.001; rPFS: P<0.001) treatment. For patients without IDC-P, DOC had comparable therapeutic efficacy with ABI. In contrast, the therapeutic efficacy of DOC in patients with either IDCP pattern 1 (PSA-PFS: P=0.021; rPFS: P=0.027) or pattern 2 (PSA-PFS: P=0.003; rPFS: P=0.007) was significantly inferior to ABI.ConclusionCompared to DOC, ABI exhibited better efficacy in patients with IDC-P of either pattern. However, IDC-P pattern 2 still responded unsatisfactorily to either ABI or DOC therapy. Novel therapeutic strategies appropriate for IDC-P pattern 2 need to be further investigated in the future.

The development of castration-resistant prostate cancer (CRPC) heralds significant morbidity and an incurable condition. Since 2004, there are now six proven life-prolonging therapies available, including androgen receptor pathway inhibitor (ARPI) , chemotherapeutic agents, radiopharmaceutical, and immunotherapy for the first-line management of metastatic CRPC. Recent advances have seen enzalutamide and apalutamide approved by US FDA for the treatment of nonmetastatic CRPC, with darolutamide the latest ARPI demonstrating efficacy in nonmetastatic CRPC. ARPI is the treatment of choice in the first-line setting for most CRPC patients, and this approach has been endorsed by clinical guidelines and expert consensus, although treatment must be individualized. Advances in the molecular profiling of CRPC promise to select suitable patients for trials involving targeted therapy and identify biomarkers to guide treatment selection. This review contains 2 figures, 1 table, and 54 references.
