PURPOSE: We study toxicity and efficacy of sequential intravesical therapy with mitomycin C and bacillus Calmette-Guerin (BCG) in patients with intermediate or high risk superficial bladder cancer compared to the use of intravesical mitomycin C alone. MATERIALS AND METHODS: Patients with intermediate and high risk papillary superficial bladder cancer and carcinoma in situ were randomized after transurethral resection between 4 weekly instillations with 40 mg. mitomycin C followed by 6 weekly instillations with BCG (group 1, 90 patients) or 10 weekly instillations with mitomycin C (group 2, 92 patients). RESULTS: The frequency of bacterial and chemical cystitis, and other local side effects was similar in both groups. Allergic reactions, including skin rash, were more frequent in the mitomycin C only group (12 of 92 patients versus 5 of 90, p = 0.08), and other systemic side effects were more frequent in the sequential group (16 of 90 versus 8 of 92, p = 0.07). After a median followup of 32 months the number of recurrences (sequential 35 of 90 patients versus mitomycin C only 42 of 92, p = 0.36) and progression (5 of 90 versus 4 of 92 respectively, p = 0.70) were similar in both groups. CONCLUSIONS: We did not find any major differences in toxicity or treatment efficacy with intravesical mitomycin C and the sequential use of BCG or mitomycin C for intermediate and high risk superficial papillary bladder cancer.
