ABSTRACT

Objective To evaluate the impact of different factors on long-term results in cervical carcinoma patients initially treated by surgery followed by radiotherapy. Methods In 1998, 525 cervical carcinoma patients were admitted, among whom 346 patients were first treated by surgery. 302 of these 525 patients were given postoperative radiotherapy. The stage distribution of these 302 patients were: stage I 142;stage Ⅱa 121;stage Ⅱb 23;and stage Ⅲa 16. ~ 60 Co ? or 6MV X-ray was used for radiotherapy. Perpendicular portals were alternately irradiated to 44-50Gy/4-5 week. Extending the portal, increasing the dose after constricting portal, adding intracavitary afterloading irradiation and adjuvant chemotherapy were carried out according to the different clinical requirements. Results The 5-year survival rate was 89.4%,77.7%,56.5% and 56.3% in stage I, Ⅱa, Ⅱb and Ⅲa lesion, respectively(?~2=22.22,P
