[Results of the multidisciplinary treatment of invasive bladder cancer].
Of the 843 patients with bladder cancer treated at Kyoto University between 1965 and 1984, 156 patients (18.6%) received total cystectomy. Between 1980 and 1984, 60 patients underwent multidisciplinary treatment with 4,000 or 2,400 rad adjuvant preoperative radiation therapy to the whole pelvis followed by radical cystectomy with or without postoperative adjuvant chemotherapy. The 5-year survival rate for the 65 patients with pelvic lymphadenectomy was 66% and that for the 40 patients without lymphadenectomy or only biopsy was 35%. The 5-year survival rate after radical cystectomy for 20 bladder cancer patients with regional lymph node metastasis was 11% and 73% for 59 patients without lymph node metastasis (p less than 0.001). The survival rate of multidisciplinary treatment protocol for muscle invasive bladder cancer was 55% a significantly (p less than 0.05) improved survival compared to the historical control. For analysis, the patients were divided into 2 categories according to histological criteria for evaluation of therapeutic effects for preoperative radiation by Ohoshi and Shimosato. The two groups were non-responder: grade I and IIa changes and responder: grade IIb, III and IV. Survival for responders and non-responders revealed significant differences (p less than 0.05), 87% for 28 responders and 48% for 24 non-responders.
