title: Intracavitary irradiation for carcinoma of the urinary bladder: rationale, technique, and preliminary results.
abstract: Twelve patients with transitional cell carcinoma of the bladder have been treated employing a combination of external beam radiation (4000 to 5040 cGy/4 to 5.5 weeks) supplemented by intracavitary irradiation (1500 to 3000 cGy mucosal dose) using a triple lumen balloon catheter containing a central 137Cs source. The rationale, patient selection, and preliminary results are reported, and the technique of the intracavitary brachytherapy is described.
