Postoperative statin use and risk of biochemical recurrence following radical prostatectomy: results from the Shared Equal Access Regional Cancer Hospital (SEARCH) database.
Abstract
OBJECTIVE: To investigate the effect of statin use after radical prostatectomy (RP)
on biochemical recurrence (BCR) in patients with prostate cancer who never received
statins before RP. PATIENTS AND METHODS: We conducted a retrospective analysis of
1146 RP patients within the Shared Equal Access Regional Cancer Hospital (SEARCH)
database. Multivariable Cox proportional hazards analyses were used to examine differences
in risk of BCR between post-RP statin users vs nonusers. To account for varying start
dates and duration of statin use during follow-up, post-RP statin use was treated
as a time-dependent variable. In a secondary analysis, models were stratified by race
to examine the association of post-RP statin use with BCR among black and non-black
men. RESULTS: After adjusting for clinical and pathological characteristics, post-RP
statin use was significantly associated with 36% reduced risk of BCR (hazard ratio
[HR] 0.64, 95% confidence interval [CI] 0.47-0.87; P = 0.004). Post-RP statin use
remained associated with reduced risk of BCR after adjusting for preoperative serum
cholesterol levels. In secondary analysis, after stratification by race, this protective
association was significant in non-black (HR 0.49, 95% CI 0.32-0.75; P = 0.001) but
not black men (HR 0.82, 95% CI 0.53-1.28; P = 0.384). CONCLUSION: In this retrospective
cohort of men undergoing RP, post-RP statin use was significantly associated with
reduced risk of BCR. Whether the association between post-RP statin use and BCR differs
by race requires further study. Given these findings, coupled with other studies suggesting
that statins may reduce risk of advanced prostate cancer, randomised controlled trials
are warranted to formally test the hypothesis that statins slow prostate cancer progression.
