โฆ Synopsis
A multicenter trial for postoperative prophylaxis of superficial Ta-T1, G1-G2 bladder cancer was performed. Intravesical instillation using either 20-30 mg adriamycin or 20 mg mitomycin C per dose was carried out for 4 weeks or 2 years. Patients without instillation served as controls. A total of 259 patients was considered eligible for the evaluation. The instillation group showed a better disease free survival rate than the control group. Better prophylactic effects of instillation therapy were observed when one of following factors was present: multiple tumors, large tumors, T1 and G2 bladder cancer. The total dose of drug instilled seemed to correlate with the effects, but there were no differences between adriamycin and mitomycin C. The side effects were minimal and temporary.

From October 1983 to September 1985, 84 patients with superficial bladder tumor (Ta, Tl, Tis) were treated with sequential instillation of mitomycin C (MMC) and adriamycin (ADM). Doses of 20 mg MMC on day 1 and 40 mg ADM on day 2 were instilled into the bladder and retained for at least 2 h; this wa
