[External and intracavitary afterloading radiotherapy of cervical cancer: a report of 110 cases].

Radiation therapy is one of the major methods among the multidisciplinary treatments for carcinoma of the uterine cervix. A series of 110 patients with carcinoma of uterine cervix treated from May 1987 to December 1987 by 3-channel (Cs-137) Buchler afterloading was presented. The youngest patients was 31 while the oldest was 78 years old with an average age of 56 years. Squamous cell carcinoma was found in 104 of the patients, while 6 had adenocarcinomas. There were 2 cases with Stage I, 17 Stage II and 91 Stage III lesions. Whole pelvis irradiation was delivered with two large parallel anterior-posterior opposite fields. The dose was 2.5-3Gy given in one field a day, three times a week, the total dose was 42-52Gy at the middle line plane of pelvis. Intracavitary irradiation was started a week following the external irradiation. The dose rate at point A was 0.1-0.26Gy/min. The project was designed to deliver 25-30 Gy to point A by 5-6 frequency. The over-all 5-year survival rate of the whole series was 70%, with 82% for Stage II and 67% for Stage III lesions. The frequency of late rectal and bladder reactions was 10.9% and 4.5%, respectively.
