Intravesical bacillus Calmette‐Guérin is superior to mitomycin C in reducing tumour recurrence in high‐risk superficial bladder cancer: a meta‐analysis of randomized trials

Tumour recurrence was significantly lower with intravesical BCG than with mitomycin C only in those patients at high risk of tumour recurrence. However, there was no difference in disease progression or survival, and the decision to use either agent might be based on adverse events and cost.
