Radon in treatment of infiltrating carcinoma of urinary bladder

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.
