[Intra-arterial CDDP and CDDP plus THP-ADM therapy for bladder cancer].
From 1983 to 1988, 20 patients (group A: 3 stage T1, 4 stage T2 and 13 stage T3-4 tumors) with bladder cancer were treated with single injection of CDDP (150-200 mg/body), and 28 patients (group B: 4 stage T1, 9 stage T2 and 15 stage T3-4 tumors) were treated twice with injection of CDDP (100 mg/m2) and THP-ADM (40 mg/m2) mixture from the internal iliac artery. As a rule, one half of the agents was equally given for the both sides, while 75% dose was given to the tumor side to the case with unilateral localized tumors. Then total or partial cystectomy was followed. When residual invasive cancer was pathologically present in operative specimens, patients underwent three to six courses of adjuvant chemotherapy including CDDP. Clinical response rate (CR+PR) to the intra-arterial chemotherapy in group A and B were 39% and 62%, respectively. Pathological response rate (grade 3 and grade 4 by Oboshi and Shimozato classification) were 17% in both group. After total cystectomy, the 2-year cancer specific survival rates of 17 patients in group A and 22 patients in group B were 75% and 59%, respectively. The 2-year cancer specific survival rates of 8 patients in group A and 10 patients in group B with pT3b were 63% and 54%, respectively. No cancer death occurred thereafter in the patients of group A during another three years. The 3-year cancer specific survival rate of 9 patients after partial cystectomy (3 in group A, 6 in group B) was 86%.(ABSTRACT TRUNCATED AT 250 WORDS)
