摘　　要：目的为了评估“Ｂｕｃｈｌｅｒ”（布克勒）后装腔内放疗机，回顾分析２３５例宫颈癌（Ⅱ、Ⅲ期）的１０年的疗效。材料与方法本文总结我院１９８３年１０月至１９８５年１２月间应用“Ｂｕｃｈｌｅｒ”（布克勤）后装机合并６０Ｃｏ或９ＭｅＶ直线加速器对Ⅱ、Ⅲ期的宜颈癌２３５例进行根治性放射治疗。放疗剂量：腔内放疗为６０Ｇｙ（Ａ点），阴道与宫腔剂量比为１：１，随后外射则（Ｂ点）采用盆腔４野放射，剂量４６Ｇｙ。结果全组患者随访１０年，其中５人失访，随访率为９７．８７％（Ⅱ、Ⅲ期，宫颈期，宫颈癌的１０年生存率分别为７５．２４％（７６／１０１）和５３．７３％（７２／１３４），总１０年生存率为６２．９８％（１４８／２３５）。结论＂Ｂｕｃｈｌｅｒ＂（布克勒）后装腔内治疗机对宫颈癌的远期疗效大致与镭疗相仿，但其治疗合并症一放射性直肠炎和放射性阴道炎均高于镭疗。Pnrpose In oder to evaluate the treatment result of radiotherapy for 235 cases of cervix cancer(stage Ⅱ,Ⅲ)with HDR(3K)”Buchier”afterloading machine.Materials and Methods From Oct,1983 to Dec,1985.235 cases of cervix carcinoma(stage Ⅱ.Ⅲ)were confirmed by pathology in our hospital.All patients were treated by combination of afterloading irradiation with 60 Co or 9 Mev linear accelerator external irradiation The irradiation dose was 60 Gy (point A)by intracavitary irradiation with the proportion of 1:1 of vaginal and uterine and 46 Gy(point B)by external irradiation for pelvic using four irradiative fields. Results All patients were followed up for 10 year,5 cases were lost to follow-up with the follow-up rates of 97.87%(230/235 The 10 year survivals for stage Ⅱ and Ⅲ were 75.24%(75/101)and 53.73%(72/134)Total 10 year survival rate was 62.98 %(149/235).Conclusion The long term results of afterloading brachytherapy of cervix cancer with”Buchier”machine was about similar to Radium irradiation but the postradiation prcotitis and vaginitis were higher than Radium irradiation.
