목적 : 상피내암, 초기 침윤성 자궁경부암, 또는 양성 질환으로 자궁적출술 받은 후 침윤성 자궁경부암으로 확인되어 방사선치료를 받은 환자의 치료 결과와 예후를 분석 하고자 하였다. 대상 및 방법 : 1985년 9월부터 1993년 12월까지 수술후 침윤성 자궁암으로 진단되어 방사선치료를 시행한 61명의 환자를 대상으로 후향적 분석을 시행하였다. 수술전 진단은 상피내암이 가장 많았으며 (38명), 초기 침윤성 자궁암 (10명), 자궁근종 (6명)등이었다. 대부분 수술후 2개월 이내에 방사선치료를 시행하였으며 3명은 추적검사중 재발암으로 확인되어 치료하였다. 8명은 강내치료만을, 47명은 외부 방사선치료만을, 그리고 6명은 강내치료와 외부 방사선치료를 같이 시행하였다. 결과 : 5년 생존율 및 무병 생존율은 각각 83.8%, 86.9% 였으며 수술 당시의 육안적 잔존병소가 있었던 경우는 38.4%로 매우 낮았다. 모두 8명의 치료실패가 있었으며 예후인자로는 후향적 병기, 잔존병소 유무, 병리조직유형이 있었다. 결론 : 조기 침윤성 자궁암은 부적절한 수술후에도 방사선치료로 효과가 좋으나 잔존병소가 있는 경우에는 예후가 불량하므로 좀 더 적극적인 치료가 필요하며, 무엇보다도 조기에 정확한 검진과 병기 결정을 시행하여 각 병기에 따른 적절한 치료가 필요하다.

Purpose : Hysterectomy without lymph node dissection was considered an inadequate treatment method for invasive uterine cervix cancer. Usually the procedure was performed inadvertently on patients who were thought to have benign or premalignant conditions preoperatively. We analysed radiotherapy results of such patients to evaluate survival rates, failure patterns and prognostic factors according to various conditions. Materials and Methods : Sixty one patients undergoing hysterectomy in the presence of invasive cervical carcinoma were reviewed retrospectively. Preoperative diagnosis were carcinoma in situ (38 cases), severe dysplasia (2), myoma (6), uterine bleeding (4), uterine prolapse (2). and early invasive cervix cancer (10) (One patient had myoma and carcinoma in situ coincidently). Patients received postoperative megavoltage radiotherapy from August 1985 to December 1993, and minimum follow-up period was 24 months. Eight patients received ICR only, 6 patients ICR and external radiation, and 47 patients received external radiation therapy only. Results : Overall 5-year survival rate and relapse-free survival rate werer 83.8%, 86.9% respectively. For patients with retrospective stage IA, IB, IIB (gross residual after surgery), and vaginal cuff recurrence were 90.9%, 88.8%, 38.4%, and 100% respectively There were 8 cases of treatment failure, most of them (5/8) were in patients with gross residual disease, other patients were full thickness involvement of cervix wall (2/8) except one. Patients with early vaginal cuff recurrence and microinvasive cervical cancer (stage IA) had no treatment related failure Prognostic factors affecting survival by univariate analysis were status of residual disease, tumor histology and retrospective stage. Conclusion : Adjuvant radiotherapy appeared to be effective treatment method for patients with presumed stage IA, IB and early local recurrent disease after inadvertent hysterectomy Survivals for patients with gross disease remained after inappropriate hysterectomy was poor, So, early cancer detection and Proper management with precise pretreatment s1aging is necessary to avoid inadherent hysterectomy especially in the cases of gross residual disease.
