Abstract
From May 1979 through December 1981 a total of 524 patients with carcinoma of the uterine cervix were treated by radiation therapy with curative intent. Among the 524 patients, 350 were treated with a high-dose-rate (HDR), remote-controlled, afterloading intracavitary irradiation (ICR) system using a cobalt source (Ralstron), and 168 patients received a low-dose-rate (LDR) ICR using a radium source. External beam irradiation with a total dose of 40-50 Gy to the whole pelvis followed by intracavitary irradiation with a total dose of 30-39 Gy in 10-13 fractions to point A was the treatment protocol. ICR was given three times a week with a dose of 3 Gy per fraction. Five-year actuarial survival rates in the HDR-ICR group were
1979년 5월부터 1981년 12월까지 총 524명의 자궁경부암 환자가 근치적 목적하에 방사선 치료를 받았다. 524명의 환자중, 356명이 코발트 선원을 사용한 원격 조정 아프터로딩 고선량률 강내조사 시스템 (Ralstron)으로써 치료받았으며 168명의 환자는 라듐 선원을 사용한 저선량률 강내 조사를 받았다. 외부조사는 골반부 전체에 총 40-50 Gy가 주어졌으며, 이어서 A지점에 10-13번에 걸쳐 30-39 Gy의 강내 조사를 시행하는 치료지침이 사용되었다. 강내조사는 3 Gy씩, 일주일에 세번 주어졌다. 고선량률 강내조사를 받은 군에서의 5년 실제생존률은 IB기 (N=20)가
