[Clinical studies of the treatment of bladder tumor and its effects--experience in 86 cases].
Prognosis on evaluable 86 patients with primary bladder tumor seen during the 10 years up to 1985 was evaluated in relation to treatment mode and tumor stage. The majority of patients underwent multimodal therapies including surgery, chemotherapy and immunotherapy with picibanil (OK432). Transurethral resection of the tumor was performed as an initial surgical treatment in 49 patients, 9 of whom ultimately underwent total cystectomy. After leaving hospital, these patients were kept on immunotherapy with OK432 and topical chemotherapy with bladder instillation of mitomycin C or adriamycin (ADM) with or without systemic administration of Tegefur as long as possible. The overall actual 5-year survival rate for the patients treated by initial transurethral resection was 80%. Recurrence rate for these 49 patients was 35%. Total cystectomy with urinary diversion was performed in 37 patients who had been placed postoperatively on systemic administration of Tegafur and immunotherapy with OK 432 as long as possible. The overall actual 5-year survival rate for the patients treated with total cystectomy was 54%. The patients with pT2 and lower stage tumor had an actual 5 year survival rate of 72%, while the patients with pT3 and higher stage tumors had a survival of 10%. The high recurrence rate in the patients with superficial tumor and the low actual survival rate of the patients with pT3 and higher stage remain a problem in the treatment of bladder tumor. In recent trials, bacillus Calmette-Gúerin instillation therapy has been initiated to lower the recurrence rate in superficial tumor and we have had a satisfactory 4-year result.(ABSTRACT TRUNCATED AT 250 WORDS)
