title: A trial of prophylactic radiotherapy for non-infiltrating bladder tumours.
abstract: In series of 56 cases of non-invasive bladder tumours there was a 61.8% recurrence rate after endoscopic treatment. In 29 cases a trial of prophylactic, very low dose (750 rad) radiotherapy was given; this was administered within a few days of the primary treatment. Twenty-seven cases received no radiotherapy. Over follow-up periods of 2 to 5 years there were recurrences in 12 of the irradiated group compared with 11 out of the 27 controls.
