Purpose: The effect of statins on prostate cancer recurrence has been investigated in several studies with inconsistent results. We investigated whether statins were associated with biochemical recurrence in a large cohort of men after radical prostatectomy. We also performed a meta-analysis of existing studies. Materials and Methods: A total of 1,446 patients who underwent radical prostatectomy at New York University were followed a median of 57 months for biochemical recurrence events. Baseline demographic and clinical characteristics were compared between 437 statin users and 1,009 nonusers. Kaplan-Meier curves and Cox models were used to examine biochemical recurrence-free survival by statin use. A meta-analysis was performed with data from our cohort and 5 published studies using the random effects model. Results: Statin users were slightly older and more likely to have diabetes (p <0.01). They were similar to nonusers in race and body mass index. Although preoperative prostate specific antigen and tumor stage were similar between the 2 groups, the proportion of patients with pathological Gleason score 7-10 tumors was slightly higher among statin users (p = 0.03). The biochemical recurrence-free survival rate was 87.4% and 89.0% for statin users and nonusers, respectively, at the end of followup (log rank p = 0.26). Overall biochemical recurrence was not associated with statin use (HR 1.15, 95% CI 0.82-1.61). Results were similar when patients were stratified by D'Amico low and intermediate or high risk groups. Meta-analysis revealed no overall association between statins and biochemical recurrence (pooled HR 1.00, 95% CI 0.80-1.19). Conclusions: Our findings are consistent with the results of the meta-analysis, which indicated that preoperative statin use does not impact the overall risk of biochemical recurrence.
