What is known and objective To evaluate the effects of statin use on the treatment outcomes (i.e. overall survival and cancer‐specific survival) among advanced prostate cancer (PCa) patients treated with androgen deprivation therapy (ADT) or abiraterone/enzalutamide. Methods The original studies, examining the effects of statins on the outcomes (i.e. overall survival and cancer‐specific survival) among PCa patients treated with ADT or abiraterone/enzalutamide, were identified through a systematic search by two independent reviewers in the PubMed, Cochrane, Embase, American Society of Clinical Oncology and European Society of Medical Oncology databases. Databases were searched using keywords (abiraterone OR enzalutamide OR androgen deprivation therapy) AND statin. In total, nine eligible studies from 111 references were included for final analysis. Results and discussion Statin use significantly lowered the risk of all‐cause mortality (100 709 patients, HR = 0.73, 95%CI = 0.64‐0.83, P < .00001) and the risk of cancer‐specific mortality (100 343 patients, HR = 0.64, 95% CI = 0.53‐0.77, P < .00001) in advanced PCa patients treated with ADT. The sensitivity analysis showed that the results were reliable. However, it could not generate reliable evidence in patients with metastatic castration‐resistant prostate cancer (mCRPC) treated with abiraterone/enzalutamide, as relevant studies were limited and had inconsistent results. What is new and conclusion The review indicated that the use of statins in combination with ADT was associated with better all‐cause survival and cancer‐specific survival in patients with advanced PCa. Randomized controlled trials should be conducted to establish efficacy of statins among PCa patients.
