肺癌的X刀放疗及CT随访观察

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。

The Radiotherapy of Pulmonary Carcinoma by X-ray Knife and CT Followed up

Objective To investigate the value of X-ray Knife in the stereotaxis radiotherapy of lung cancer.Methods 52 cases with pulmonary carcinoma were treated with X-ray knife,before and after that,general radiotherapy was applied.After whole radiotherapy,2 or 3 months later,all patients were followed by CT scan.The changes of tumor and clinical appearances were compared before and after therapy.The curative effect was estimated according to clinical appearances and CT findings.Results 6 patients were complete response(11.5%) ,29 patients were partial response(55.8%) and 13 patients were no changes or reduced less than 50%.The total responsive rate was 92.3%.Conclusion The treatment of lung cancer with X-ray Knife can give tumor accuracy high dosage irradiation.The short term therapeutic effectiveness is significant and safe on clinical.
