OBJECTIVE:To examine the association between statin use and prostate cancer (PC) stratified with D'Amico risk groups and biochemical recurrence (BR) in patients undergoing radical prostatectomy (RP).
PATIENTS AND METHODS: All medical charts of patients managed from 2004 to 2008 for PC with RP were reviewed retrospectively. The use and the type of statin were identified. Patients were split according to the use (S+) or not (S-) of statin. The two groups were compared using the Chi2test. A logistic regression was performed for multivariate analysis.
RESULTS:Overall, 377 patients were included. Mean age was 64 (48-76) (median, range). Ninety-seven patients (27.5%) used statin for at least a year. Groups S- and S+ were comparable in terms of age, obesity, diabetes, preoperative PSA, biopsy Gleason score or clinical stage. The use of statin was statistically associated with D'Amico risk groups (P=0.003). The number of high-risk PC was higher in Group S+ (23.7% vs. 10.7%) with an odds ratio of 2.4 (P=0.009). With a mean follow up of 33±10 months, the overall 2-years-BR was 89%. The 2-years-BR was higher in the S+ (93% vs. 88%, P=0.16). After adjustment, this difference was statistically significant with a hazard ratio of 0.46 (P=0.036).
CONCLUSION: The use of statin was associated with high risk PC in this study. Surprisingly, the statin use seem also to be associated with better disease-free survival, independently of other risk factors.
