We evaluated the survival rate and time to recurrence for 114 patients in whom an initial histological diagnosis of stage B1 or B2 bladder tumor was made between 1974 and 1983. The 5-year survival rates for stages B1 and B2 disease, respectively, were 63 and 38 per cent in 43 patients treated by transurethral resection alone, 48 and 54 per cent in 40 treated by preoperative radiation and radical cystectomy, 33 and 25 per cent in 15 treated by radical cystectomy alone, and 53 and 11 per cent in 16 treated by definitive radiation therapy alone. Similar results were found among the groups with regard to time to development of metastases. The distribution of stage, grade and number of tumors was not significantly different among the treatment groups. Patients in the transurethral resection group were older, and had smaller tumors and more medical problems. Comparing transurethral resection of muscle invasive bladder tumors to standard radical surgery with or without radiotherapy yielded comparable long-term survival and time to distant recurrence.
