Abstract
One hundred and twenty six patients with early uterine cervical cancer who had been treated at Departmen of Radiation Oncology of Korea University Hospital from Jan.1981 to Dec.1988 were analysed retrospectively by the treatment result and pattern of of failures. All patients had stage Ia to IIa disease and were grouped whether they had combination of operation and postop irradiation or radiation therapy alone. 1) Sixty six patients belonged to the combination treatment group and 60 patients to the radiation alone group. 2) Combination group consisted of $18.1\%$(12/66) stage Ia, $71.2\%$(47/66) stage Ib and $10.6\%$ (7/66) stage IIa patients. There were no stage Ia, 18.8$\%$(l1/60) stage Ib and 81.6$\%$(49/60) stage IIa patients for RT alone gronp. 3) There were total 23$\%$(29/126) treatment failures,13 patients in combination group and 16 patients in RT alone group. In 66 patients of combination group, they were found to have 5 locoregional failures, 7 distant failures and 1 at both sites. In 60 patients of RT alone group, 9 locoreginal failure and 7 distant failures occured. Eighty six percent (25/29) of total failures appeared within 18 month after completion of treatment. About 60$\%$ of the patients with regional recurrences which were located at pelvic side wall or pelvic lymph nodes paesented their recurrent disease after 1 year of completion of treatment, whereas same percent of distant failures appeared within 6 month. 5) In RT alone group, the first sites of distant failure were mostly para-aortic lymph node and/or left supraclavicular lymph node (71.4$\%$,5/7). In combination group, various sites such as inguinal lymph node, mediastinal lymph node, liver, lung and bone appeared first or at the same time with para-aortic and supraclavicular lymph node metastasis. 6) Logistic regression analysis was done for multivariate analysis of the factors contributing to locoregional and distant failures. In combination group, adequacy of the resection margin and the presence of positive pelvic node were found to be the most significant factors (p=0.0423 & 0.0060 respectively). In RT alone group, less than complete regression of the tumor at the end of treatment was the only significant contributing factor for the treatment failures (p=0.0013) with good liklihood ratio.
1981년 1월부터 1988년 12월까지 고려대학교 의과대학 치료방사선과에서 제1기에서 2기초까지의 자궁경부악성종양으로 방사선치료를 받았던 126명의 환자를 수술과 방사선치료의 병행요법군(66)과 단독방사선치료(60)군의 두군으로 나누어 그 치료실패의 양상과 요인을 분석하였다. 총 126명 중 29명인 23$\%$의 환자에서 국소재발이나 원격전이를 보였으며 각 군 사이에 병기별로 의미있는 차이를 보이지는 않았다. 29명 중 25명인 86$\%$의환자에서 치료종결후 18개월이내에 치료실패를 보였으며 원격전이의 평균 시기는 국소적인 재발보다 빨라 약 60$\%$의 원격 전이 가 6개월 이내에 발생되었다. 첫 원격전이의 장소로는 단독방사선군에서는 주로 복부임파절이나 쇄골 상부임파절이 많았던 반면 병행요법군에서는 이를 제외한 원격임파절, 폐, 간 및 골전이가 많았던 것으로 나타났으며 이는 통계학적인 유의성이 있었다. 각 군에서 치료실패에 기여하는 요소를 알아내기 위해 조직병리학적, 또는 임상적인 위험요소들에 대해 다변수 분석을 시행한 결과 병행요법군에서는 불충분한 제거 범위 (p=0.0423) 및 전이 성 골반임파절 (p=0.0060)의 존재가, 단독요법군에서는 치료 종결시 종양의 불완전관해(p=0.0013)가 가장 의미있는 요소로 관찰되었다.
