Analysis of radiotherapy in Kumamoto National Hospital, 2

From 1967 to 1985, 1078 patients with gynecological neoplasms were treated by radiotherapy in our hospital, and 922 cases of them were uterine cervical carcinoma, 40 cases were endometrial carcinoma, 56 cases were ovarial cancer and 60 cases were other cancer. Of these 922 patients with uterine cervical carcinoma, 683 patients were treated by irradiation alone and another 239 patients were treated by postoperative irradiation. The results of radiotherapy for uterine cervical carcinoma from 1961 to 1979 were analyzed. The five-year survival rate from 1961 to 1966 with deep x-ray therapy were 23 %, and from 1967 to 1979 with 60Co unit were 44 %. By improvement of methods of radiotherapy, the five-year survival rate during the period of 1975 to 1979 (54 %) became higher than that during the period of 1967 to 1974 (37 %). The survival rate in the postoperative group during the period of 1975 to 1979 was approximately 20 % higher than the that during the period of 1967 to 1974. The effect of radiotherapy was dependent on the therapeutical equipment and methods of treatment in our hospital. Starting from 1981, radiotherapy for uterine cervical carcinoma has been using linear accelerator and 60Co remote afterloading system. (author)
