Intracavitary radiotherapy with Cf-252 for uterine cervical carcinomas at the Japan Cancer Institute Hospital

Cf-252 intracavitary radiotherapy using a specially designed remote afterloading system and treatment facility was performed in patients with stage IIB and IIIB cervical carcinoma. Cf-252 was effective for both squamous cell carcinoma and adenocarcinoma. For stage IIB 7/7 (100%) had local control, 1/7 (14%) injury, and 6/7 (85%) had long term survival NED. For stage IIIB disease 3/11 (27%) had local control and long term survival. With the varying doses and treatment protocols used, complications were noted, mostly recto-sigmoid. Further study of Cf-252 use in cervix cancer and of its effect on the recto-sigmoid mucosa is required. Both local control and long-term survival (--5 year) were obtained using Cf-252 intracavitary therapy.
