目的探讨影响宫颈癌放疗疗效的预后因素。方法１９８４年５月至１９９２年１２月收治宫颈癌 ６６例，其中手术加放疗１０例；腔内后装放疗加~（６０）Ｃｏ外照射 ６例；~（６０）Ｃｏ外照射２５例，~（６０）Ｃｏ加体腔筒外照射２５例。结果 治疗后的３年、５年生存率分别为５７．５８％、４６．９７％。Ⅰ、Ⅱ、Ⅲ、Ⅳ期的５年生存率分别为１００％（２／２）、７０％（１４／２０）、３５．７１％（１５／４２）、０（０／２），Ⅱ期与Ⅲ期有显著性差别。放疗剂量＜６０Ｇｙ和６０～７０Ｇｙ的５年生存率分别为１３．３３％、４８．５７％（Ｐ＜０．０５）；放疗结束肿瘤完全消失与部分消失的５年生存率分别为 ５８．３３％、１０％（Ｐ＜０．０１）。结论 分期愈早，预后愈好，放射治疗剂量以 ６０～７０Ｇｙ为佳，放疗结束时肿瘤完全消失预后较好。
Objective To investigate the prognostic factors of cervical cancer radiotherapy. Methods From May 1984 to December 1992, 66 cases of cervical cancer were treated, including surgery and radiotherapy in 10 cases; intracavitary posterior radiation plus radiotherapy (60Co) in 6 cases; radiotherapy of ~ (60) Co in 25 cases, (60) Co plus lumen external irradiation in 25 cases. Results The 3-year and 5-year survival rates after treatment were 57.58% and 46.97% respectively. The 5-year survival rates of stage Ⅰ, Ⅱ, Ⅲ and Ⅳ were 100% (2/2), 70% (14/20), 35.71% (15/42), 0 (0/2) There was a significant difference with stage Ⅲ. The 5-year survival rates of radiotherapy doses <60 Gy and 60-70 Gy were 13.33% and 48.57%, respectively (P <0.05). The 5-year survival rates of complete disappearance and partial disappearance of tumors after radiotherapy were 58.33 %, 10% (P <0.01). Conclusions The earlier the staging, the better the prognosis, radiation dose 60 ~ 70Gy better, completely disappeared at the end of radiotherapy prognosis is good.
