title: [Results of radical cystectomy for bladder cancer].
abstract: During 7 years and 3 months from October 1983 to December 1990, 68 patients underwent radical cystectomy for primary bladder cancer at Yamanashi Medical College. Of these 68 bladder cancers, 16 were superficial and 52 were invasive. Among the 52 patients with invasive cancer, a combination chemotherapy of methotrexate and cisplatin and/or radiotherapy were given in 18 as an adjuvant therapy. All the adjuvant therapies were performed after the operation except for 2 patients with T4 bladder cancer who received chemotherapy before the operation. There were 23 recurrences and 25 deaths, 20 from bladder cancer and 5 from other causes. Of 20 bladder cancer deaths, 17 deaths (85%) were observed within 2 years after the operation. The 5-year survival rates were 92% for stage pTa-pT1, 83% for stage pT2, 80% for stage pT3a, 24% for stage pT3b and 43% for stage pT4-T4, respectively. A significant difference (p < 0.05) in survival curve was observed between pT3a and pT3b. The 5-year survival rate for pT2-pT3a without nodal metastases was as high as 89% (95% confidence limits 75 to 100%) although 18 out of 19 patients received no adjuvant therapy. On the other hand, the 5-year survival rate for pT3b-pT4 without nodal metastases (25%) was as low as that of patients for any T category with nodal metastases (35%). Most patients with tumor confined within bladder wall seemed to be cured by surgery only. Therefore, any adjuvant chemotherapy with severe side effects seemed not to be justified for these patients.(ABSTRACT TRUNCATED AT 250 WORDS)
