title: Radon in treatment of infiltrating carcinoma of urinary bladder.
abstract: Shown here are the results from the use of radon in the treatment of 146 patients with infiltrating carcinoma of the bladder. Ninety-four per cent of the tumors had invaded the muscle of the bladder; 54 per cent were Stage B2 or worse. Ninety per cent of the radon implantations were done cystoscopically. Twenty-one per cent of the patients survived five years or longer, free of recurrence. An additional 8 per cent were cured by follow-up treatment of recurrences. Complications and morbidity are minimal. Survival results compare favorably with more dangerous and debilitating methods of treatment.
