The authors reported 122 cases of T_2/T_3 bladder cancer from 1975 to 1982, with or without preoperative irradiation as a result of total bladder resection. Random biopsies were performed before surgery and the specimens for cystectomy were reviewed. The cases were divided into three groups: 42 cases in group 1, with 46 Gy/4.5 weeks, 2 Gy/day before and after surgery (16 x 16 cm), and 3 to 4 weeks after radiotherapy. In the two groups, 34 cases were treated with the irradiation field in the same way as the first group. The dose was 20 Gy/1 week, 4 Gy/day, and one week after irradiation. There were 46 patients in 3 groups, which were not irradiated before surgery. After the consultation period to February 1985, the rough and cancer-free survival rate was analyzed according to the recommendations of Peto et al.
