Treatment Result of Postoperative Radiotherapy of Carcinoma of the Uterine Cervix

조기자궁경부암의 치료에는 환자 개개의 특성에 따라 근치적수술 또는 근치적방사선치료가 행해지고 있으며, 그 치료성적은 비슷한 것으로 보고되고 있다. 그러나 근치적 수술후 병리조직 소견에 따라 원발병소가 크거나, 임파절전이, 혈관 또는 임파관의 종양 침윤이 있으면 이들 소견이 없던 경우에 비해 재발이 현저히 높고, 생존율이 반으로 줄게 되므로, 이를 극복하기 위해 수출후 방사선 치료가 시행되고 있으나 생존율에 대한 기여에는 아직 논란이 많다. 이에 1979년 2월부터 1982년 9월까지 서울대학교병원 치료방사선과에서 자궁경부암으로 수술 후 방사선 치료를 받았던 203예에 대한 치료성적을 분석하여 얻은 결과는 다음과 같다. 모든 환자에 있어 actuarial 3년 생존율은 83.4%이었으며 3년 무병 생존율은 73.4%이었다. 병기에 따른 actuarial 3년 생존율은 I_B, II_A, II_B, 각각 90.7%, 69.6%, 85.2%이었다. 병기별 3년 무병 생존율은 I_B, II_A, II_B 각각 79.8%, 67.8%, 68.3%이었다. 재발은 총 203예중 51예 (25.1%)에서 관찰되었으며 이중 국소재발이 8.4%, 원격전이가 14.3%이었고, 국소재발과 원격전이가 함께 있던 경우가 2.4%이었다. 병기별 재발율은 I_B, II_A, II_B에서 각각 19.8%(18/91예), 29.1%(16/55예), 29.8%(17/57예)이어다. 합병증중 급성으로 나타난 것이 57.6%이었으나 7.4%만이 심한 증상을 보였고, 만성 합병증은 7.9%에서 관찰되었으며, 장폐색, 비뇨기계증상의 악화, 방사선 방광염등의 순이었다.

The early carcinoma of the uterine cervix may be treated by either radical surgery or radical radiotherapy according to the patient's characteristics, and the survival is high with either treatment. But, because of the size of the lesion, metastasis to lymph nodes, and vascular space invasion by tumor have all been shown to influence recurrence and survival, postoperative radiotherapy may be considered as their histopathologic finding after radical surgery. However, there are still debates on the increasing survival rates with postoperative radiotherapy. Two hundreds and three patients with carcinoma of the uterine cervix who were treated with postoperative radiotherapy from February 1979 to September 1982 in the Department of Therapeutic Radiology, Seoul National University were analyzed and following results were obtained. 3-year actuarial survival rate and 3-year disease free sruvival rate were 83.4% and 73.4% respectively and 3-year actuarial survival rates by stages were 90.7% for IB, 69.6% for IIA, and 85.2% for IIB. 3-year disease free survival rates by stage IB, IIA, IIB were 79.8%, 07.8%, 68.3% respectively. The overall failure rate was 25.1% (51/203); local recurrence rate was 8.4%, distant metastasis rate was 14.3% and simultaneous local recurrence and distant metastasis was 2.4%. Failure rates by stages were 19.8% (18/19) for IB, 29.1% (16/55) for IIA and 29.8% (17/57) for IIB. The overall acute complication rate was 57.6%; tolerable cases was 50.2% and severe cases was 7.4%. Late complication rate was 7.9% and the major late complication were intestinal obstruction. aggravated urinary symptom, radiation cystitis in order of frequency.
