Purpose: Bacillus Calmette-Guerin is an effective immunotherapy for carcinoma in situ of the bladder and it reduces recurrence from resected papillary transitional cell carcinoma of the bladder. Many patients receiving bacillus Calinette-Guerin therapy are concurrently taking statin agents, which have known immunomodulatory properties and may alter the performance of bacillus Calmette-Guerin. Some data have suggested that patients taking a statin while on bacillus Calmette-Guerin therapy experience reduced clinical efficacy. Materials and Methods: We conducted a retrospective review of 952 consecutive patients from 1978 through 2006. Time to recurrence and progression to surgery were compared between those taking and those not taking a statin by Kaplan-Meier methods and multivariable Cox regression controlling for stage and grade. Results: There were 245 (26%) patients taking a statin before bacillus Calmette-Guerin therapy and 707 not on statin therapy (74%). A total of 796 patients had recurrence overall with 214 in the statin g-roup and 582 in the other group. Median time to recurrence was similar between those who did and those who did not use a statin. On multivariable analysis statin use was not significantly associated with recurrence (hazard ratio 1.04; 95% CI 0.81, 1.34; p = 0.7) or progression to surgery (hazard ratio 0.77; 95% CI 0.52, 1.13; p = 0.17) after bacillus Calmette-Guerin therapy. Conclusions: This retrospective study in a large cohort of patients showed no statistically significant association between statin use and recurrence or progression to open surgery in patients treated with bacillus Calinette-Guerin for transitional cell carcinoma of the bladder. Based on these data patients should not be discouraged from taking statins while undergoing bacillus Calmette-Guerin treatment.
