Abstract

Mitomycin C 40 mg in 40 ml water was administered intravesically every week for 8 consecutive weeks to 60 patients with superficial bladder cancer. All patients had failed treatment with intravesical thiotepa and had evaluable disease. An objective response of 50% or greater reduction in measured tumor mucosal involvement was obtained in 68% of patients. Forty-two percent of the patients achieved a complete response, and this included 50% of patients with Grade III disease and 70% of patients with a T1 tumor. Median response duration in complete responders was 12.2 months with a range of 3.5 to 24.3+ months. Fifty-five percent of patients are still responding. Therapy was generally well tolerated, and in contrast to thiotepa, myelosuppression was not the dose-limiting effect. One third of all patients experienced symptoms of local irritation, and skin reactions were seen in 12% of patients.
