초록
1979년부터 1986년까지 자궁경부암으로 진단되어 외부방사선 및 강내 방사선 치료를 함께 받은 550명의 환자를 대상으로 직장 합병증과 방사선량에 대한 후향적 분석을 시행하였다. 전체 환자550명 중 468명은 근치적 목적으로 방사선 치료를 받았으며, 82명은 수술후에 추가적인 방사선 치료를 받았다. 이들 82명 중 43명은 수술절제연 양성으로, 31명은 원발질환의 재발로, 8명은 stump cancer로 방사선 치료를 받았다. Grade 2와 3를 포함하는 직장 합병증의 발생률은 5년에
Five hundred and fifty patients treated for carcinoma of the uterine cervix at the Department of Therapeutic Radiology, Seoul National University Hospital from 1979 to 1986, were analyzed retrospectively for late rectal complications. Of them, 468 patients received primary radiotherapy for the cervix cancer in intact uterus, and the other eighty two patients were treated postoperatively. The cumulative incidence of radiation induced rectal complication of grade 2 or 3 was 6.7% at five years. The mean rectal dose for the group of patients with complication was higher than the group without complication, and the difference was statistically significant (p<0.01). But relationship between mean rectal dose and severity of complication was not found. The frequency of complication (grade 1, 2, 3) increased as a function of radiation dose to rectum; from 16.1% for patients with rectal dose less than 6,000 cGy to 71.2% for patients with rectal dose higher than 8,000 cGy. Among various factors analyzed, history of diabetes mellitus, number of intracavitary irradiation, size of ovoid, retroflexion of uterus and the total dose delivered to rectum turned out to have significant effect on the complication.
