Transcystoscopic intracavitary irradiation for carcinoma of the bladder: technique and preliminary clinical results.
A remote controlled transcystoscopic intracavitary after-loading unit is introduced for irradiation therapy of bladder carcinoma. With intense radiation therapy a significant dose can be delivered to the tumor during a short interval. We treated 12 patients with transitional cell carcinoma of the bladder using transcystoscopic intracavitary irradiation. Of the patients 9 initially had a complete response, although within several months 3 subsequently had recurrence in a different part of the bladder. Technical difficulties and severe complications were not encountered. The preliminary results and technique of transcystoscopic intracavitary irradiation are reported.
