Article Title: The association between statin medication and progression after surgery for localized renal cell carcinoma
Abstract: Purpose Evidence suggests that statins may influence pathways of renal cell carcinoma proliferation, although to our knowledge no study has examined the influence of statin medications on the progression of renal cell carcinoma in humans. Materials and Methods We identified 2,608 patients with localized renal cell carcinoma who were treated surgically between 1995 and 2010 at our tertiary referral center. Competing risks Cox proportional hazards models were used to evaluate the relationship between statin use and time to local recurrence or progression (metastases or death from renal cell carcinoma) and overall survival. Statin use was modeled as a time dependent covariate as a sensitivity analysis. Models were adjusted for clinical and demographic features. Results Of 2,608 patients 699 (27%) were statin users at surgery. Statin users had similar pathological characteristics compared to nonusers. At a median followup of 36 months there were 247 progression events. Statin use was associated with a 33% reduction in the risk of progression after surgery (HR 0.67, 95% CI 0.47-0.96, p = 0.028) and an 11% reduction in overall mortality that was not significant (HR 0.89, 95% CI 0.71-1.13, p = 0.3). Modeling statin use as a time dependent covariate attenuated the risk reduction in progression to 23% (HR 0.77, p = 0.12) and augmented the risk reduction in overall survival (HR 0.71, p = 0.002). Conclusions In our cohort statin use was associated with a reduced risk of progression and overall mortality, although this effect was sensitive to the method of analysis. If validated in other cohorts, this finding warrants consideration of prospective research on statins in the adjuvant setting. © 2014 by AMERICAN UROLOGICAL ASSOCIATION EDUCATION AND RESEARCH, INC.
