The treatment of carcinoma of the bladder with high energy electrons

A total of 112 patients with carcinoma of the urinary bladder were treated with high energy electrons or 35 meV X-rays. The vast majority of patients had been rejected for surgery; their average age was 10 years older than in most surgical series. The 5 year survival of patients was low, only 996. Among the 112 patients, 23 were treated with photons and 89 with electrons. The only difference between the groups was the larger sagittal diameter of patients in the smaller group which did not permit treatment with electrons. While none of the X-ray irradiated patients survived 5 years, the 5 year survival of the patients receiving electrons as the chief treatment modality was 14%
