摘要
目的 探讨三维适形放疗(3DCRT)治疗老年非小细胞肺癌(NSCLC)的临床疗效.方法 50例老年NSCLC的患者全部接受WDVE-XKY808立体定向适形放射治疗系统治疗.3DCRT处方剂量为DT40～60 Gy,中位剂量为60 Gy,参考剂量曲线选定为70%～90%.分割方式:2～4 Gy/次,每次间隔1～3 d.结果 肿瘤完全缓解15例(30%),部分缓解23例(46%),总有效率为76%.1、2、3年生存率为66.3%、45.7%,30.3%.结论 3DCRT对老年NSCLC患者有较好的局部控制效果和较高的安全性,是治疗老年NSCLC的有效方法之一.
Objective To evaluate the clinical results of elderly non-small cell lung cancer patients treated with three-dimensional conformal radiotherapy (3DCRT).Methods 50 such patients were treated bv 3DCRT with 6MV WDVE-XKY808.The total SRT dose was 60 Gy prescribed at the 70%～90% isodose by multifractions of fraction size 2～4 Gy.with interfraction duration of 1～3days.Results Of fhe 50 patients.15 achieved CR and 23 PR with a total response rate of 76%(38/50).The overall1-,2-and3-year survival rates 66.3%,45.7%,30.3%.Conclusion The 3DCRT is an effective and safe treatment modality for elderly non-small cell lung cancer patients.
