ABSTRACT
Recent studies suggest that statin may benefit cancer prognosis, especially through its radiosensitization effect. But controversy exists in other studies. Hence, we performed a meta-analysis of results from 35 studies to evaluate the effect of statin use on urologic cancers.We conducted computerized search from PubMed, Embase, and ISI Web of Knowledge through May 2015, screened the retrieved references, and collected and evaluated relevant information. We extracted and synthesized corresponding hazard ratios (HR) and confidence interval (CI) by using Review Manager 5.3 and STATA 13. This review was registered at PROSPERO with registration No. CRD42015020171.We selected total 35 retrospective studies and conducted a meta-analysis of results from these studies. The pooled results suggested no benefit of statin use to bladder cancer and renal cell carcinoma, except overall survival [HRâ=â0.81, 95% CI 0.69-0.96]. However, significant improvement of prostate cancer prognosis including overall survival [HRâ=â0.82, 95% CI 0.70-0.97] and cancer-specific survival [HRâ=â0.70, 95% CI 0.59-0.83] was indicated, but not including tumor progression [HRâ=â0.84, 95% CI 0.62-1.14]. Statin use improved biochemical recurrence of prostate cancer in radiotherapy patients [HRâ=â0.68, 95% CI 0.54-0.85] but not in radical prostatectomy patients [HRâ=â0.97, 95% CI 0.82-1.15].Current evidence suggests no benefit of statin use to bladder cancer and renal cell carcinoma, except in overall survival. While statin use benefited prostate cancer patients in overall survival, cancer-specific survival but not in tumor progression; it also improved biochemical recurrence in radiotherapy patients but not in radical patients. To verify these results, randomized controlled trials are necessary.
