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.

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.
