Hormone therapy, especially androgen deprivation therapy (ADT), is effective against prostate cancer (PC), whereas long-term ADT is a risk for metabolic/cardiovascular disorders including diabetes (DM), hypertension (HT) and dyslipidemia (DL), and might result in progression to castration-resistant prostate cancer (CRPC). We thus conducted a multicenter retrospective cohort study to ask whether CRPC progression would be associated positively with HT, DM or DL and negatively with statins prescribed for treatment of DL. In this study, 1,112 nonmetastatic PC patients undergoing ADT were enrolled. Univariate statistical analyses clearly showed significant association of HT or DM developing after ADT onset, though not preexisting HT or DM, with early CRPC progression. On the other hand, preexisting DL or statin use, but not newly developed DL or started statin prescriptions following ADT, was negatively associated with CRPC progression. Multivariate analysis revealed significant independent association of the newly developed DM or HT, or preexisting statin use with CRPC progression [adjusted hazard ratios (95% confidence intervals): 3.85 (1.65-8.98), p = 0.002; 2.75 (1.36-5.59), p = 0.005; 0.25 (0.09-0.72), p = 0.010, respectively]. Together, ADT-related development of HT or DM and preexisting statin use are considered to have positive and negative impact on CRPC progression, respectively.
