目的　探讨X刀立体定向在放射治疗肺癌中的价值。方法　 5 2例肺癌患者行X刀治疗 ,治疗前后均行常规放疗 ,放疗结束后 2～ 3月行CT复查 ,比较治疗前后临床及肿瘤大小的变化情况 ,根据临床表现和CT检查结果综合判断疗效。结果　完全缓解 6例 (11.5 % ) ;部分缓解 2 9例 (5 5 .8% ) ;无变化或肿块缩小 ,缩小不足 5 0 % 13例 (2 5 % ) ;进展 4例 (7.7% )。总有效率为 92 .3 %。结论　X刀治疗肺癌可以使肿瘤局部得到准确的高剂量照射 ,近期疗效显著 ,安全可行。

Objective To investigate the value of X-knife stereotaxy in radiotherapy of lung cancer. Methods Fifty-two patients with lung cancer underwent X-knife treatment. All patients underwent conventional radiotherapy before and after treatment. CT was performed between February and March after radiotherapy. The changes of clinical and tumor size before and after treatment were compared. The therapeutic effect was evaluated according to clinical manifestations and CT findings . The results of complete remission in 6 cases (11.5%); partial remission 29 cases (55.8%); no change or mass reduction, less than 50% 13 cases (25%); 4 cases of progress (7.7%). The total effective rate was 92.3%. Conclusion X-knife treatment of lung cancer can make the tumor locally get accurate high-dose irradiation, the recent significant effect, safe and feasible.
