[Sequential intravesical chemotherapy with mitomycin C and adriamycin for superficial bladder tumor (preliminary report)].

Intravesical chemotherapy with sequential instillation of mitomycin C and adriamycin was carried out on 19 patients with superficial bladder cancer (Ta, T1 and Tis). Twenty milligram of mitomycin C on day 1 and 40 mg of adriamycin on day 2 were instilled into the bladder, this treatment being repeated weekly for 5 consecutive weeks if there were no serious side effects. The following results were obtained. Of 16 evaluable patients, 10 patients (63%) achieved complete response and 2 patients achieved partial response, 4 patients showing no response. In patients with high grade tumor, especially with carcinoma in situ, a high CR rate (6/7 or 86%) was achieved. Chemical cystitis occurred in 10 out of 19 (53%) patients. In 5 of the 6 patients who suffered from severe cystitis symptoms, treatment was discontinued. However, the symptoms resolved within 4 weeks in all patients.
