Summary In order to reduce hospitalisation time for patients receiving post-operative radiotherapy a phase I–II study of intracavity balloon brachytherapy was instituted. An indwelling balloon catheter was implanted during the closing phase of the initial operation. Starting on the second or third postoperative day the catheter was afterloaded with a high dose rate isotope via a remotely controlled afterloading system. The treatment consisted of 10–12 fractions over a period of 5–6 days, with each treatment session requiring approximately 15 minutes. No external beam radiation was given. Forty-four newly diagnosed patients were treated. A total dose of either 60 Gy (33 patients) or 72 Gy (11 patients) was given. The overall median survival was 11.7 months, (range 2.7–50.9). The treatment was well tolerated and none of the applicators were removed prematurely. The total median hospital stay for this group of patients was significantly reduced compared to more conventional protocols. This study indicates that intracavity high dose rate balloon brachytherapy can achieve survival rates equivalent to those of conventional radiotherapy and is both cost and time efficient.
