초록
목적 : 식도암의 빈도는 계속 증가하고 있다. 근치적 수술이 가장 적절한 치료방법으로 알려져 있으나 수술의 대상이 되는 환자는 많지 않으며 방사선치료가 중요한 역할을 하고 있다. 저자들은 방사선치료만으로 치료를 받은 식도암 환자를 대상으로 후향적 분석을 시행하였다. 대상 및 방법 : 1979년 6월에서 1992년 12월까지 289명의 식도암 환자가 서울대학교병원 치료방사선과에서 치료를 받았다. 이 중에서 84명은 다음의 이유로 분석대상에서 제외되었다; 쇄골상림프절 외의 원격전이 22명, 4500cGy 미만의 불완전 방사선치료 52명, 추적관찰 불가능 10명. 따라서 205명이 이 분석의 대상이며, 생존한 환자의 추적관찰 기간은 77개월에서 180개월이었다. AJCC 분류법에 의한 병기 분포는 I기 2명, IIA기 104명, IIB기 26명, III기 48명, IV기 25명이었다. 모든 환자는 방사선치료만 시행 받았다. 방사선치료 선량의 범위는 4500 cGy에서 6980cGy까지로 중앙값은 5940cGy 였다. 결과 : 모든 환자의 생존기간의 중앙값은 11개월이었고, 2년과 5년 및 10년 생존률은 각각 22.4
Purpose : The incidence of esophageal carcinoma is increasing. Radical surgery is the treatment of choice, but large proportion of the esophageal cancer patients are with unresectable disease at the time of initial diagnosis, so radiation therapy has been the major treatment modality. We carried out retrospective analysis to see the outcome and prognostic factors of radiation therapy alone for esophageal carcinoma. Methods and Materials : From June of 1979 through December 1992, 289 patients with esophageal carcinoma were treated with radiation therapy alone at Department of Therapeutic Radiology, Seoul National University Hospital. Of these patients, 84 patients were excluded as they were ineligible for the current analyses. Twenty-two patients had distant metastasis other than supraclavicular lymph node metastasis, 52 patients received less than 45 Gy, and 10 patient were lost from follow-up. Therefore 205 patients constituted the base population of this study. According to AJCC s1aging system, there were 2 patients with stage 1, 104 with stage IIA, 26 with stage IIB, 48 with stage III, and 25 with stage IV Radiation dose ranged from 4500 cGy to 6980 cGy with median dose of 5940 cGy. Follow-up period of the alive patients ranged from 77 to 180 months. Results : The Median survival period of all the patients was II months and the 2-, 5-, and 10-year overall survival rates were 22.4
