title: The results of a series of 963 patients with transitional cell carcinoma of the urinary bladder primarily treated by radical megavoltage X-ray therapy.
abstract: The results are reported of a large series of patients with transitional cell cancer of the bladder, treated in Edinburgh between 1971 and 1982. Analysis of pre-treatment characteristics for patients with transitional cell bladder cancer showed that tumour category was significantly associated with grade and tumour size. Complete local tumour regression at follow-up cystoscopy was achieved in 45.9% of patients who completed radical megavoltage X-ray therapy. Patients with grade 2 or 3 cancer, a solid cancer or a tumour of less than 8 cm in size had significantly improved complete regression rates. Lasting local tumour control after initial complete regression was better in patients with grade 3 cancer. Complete regression was associated with improved survival for all but patients with T1 cancer. The poorest (uncorrected) survival rates were seen in patients over 79 years of age, those with T4 cancer, an ulcerated cancer, a grade 3 cancer or a tumour of more than 7 cm in size. Metastases were more often seen in patients with grade 3 or T3/T4 cancer. Severe late radiation-related complications were seen in 14.8% of patients.
