Impact of intravesical chemotherapy on recurrence rate of recurrent superficial transitional cell carcinoma of the bladder: results of a meta-analysis.

Intravesical chemotherapy appears to have a major impact on decreasing the chance of recurrence of recurrent superficial bladder cancer. Three year recurrence is decreased by as much as 70% when compared with TURB alone. These data are in contrast to prior analyses suggesting only modest efficacy of such treatment in this clinical setting.
