摘要
从１９８７年１月～１９９１年１２月应用西德Ｂｕｃｈｌｅｒ后装机配合６０ＣＯ体外放射治疗宫颈癌１７２例，近期有效率为９６．５％，后装治疗组与常规镭疗组３年生存率分别为６０％与７０．５％，差异无显著性（Ｐ＞０．０５），但放疗后遗症后装组少于镭疗组，显示高剂量率１３７Ｃｓ后装治疗是一种能取代镭疗的先进治疗技术．
From January 1987 to December 1991,172 cases of cervical cancer were treated with high dose-rate137 Cs afterloading intracavitary therapy(Buchler machine)combined with external radiotherapy.The total objective response of shortime was 96.5%,The 3 year survival rate of afterloading therapy group (60.8%)was similar to that of the conventional radium therapy group(70.5%)(P>0.05),but the side-effects in the afterloading therapy group were less observed.All this proved that afterloading intracavitary therapy could replace the conventional radium therapy.
