摘　　要：目的观察老年非小细胞肺癌立体定向放疗疗效,并探讨其预后因子。方法128例老年非小细胞肺癌患者行常规放疗结合立体定向放疗,定期随访。结果全组患者1年生存率65.72%,单因素分析表明肿瘤体积、肿瘤剂量、卡氏评分影响近期结果,多因素分析仅肿瘤体积和肿瘤剂量为近期疗效预后因子,与生存期有关的预后因素为近期疗效、肿瘤剂量、临床分期。结论立体定向放疗可延长生存时间,对Ⅲ期患者,肿瘤剂量提高至72Gy是安全的。Objective To observe the effect of stereotactic radiotherapy （SRT） for non-small cell lung cancer（NSCLC） of old patients. Method 128 NSCLC old patients receive common radiotherapy and SRT. The results was followed. Results 1-year survival rate is 65.72% for all patients on univariate analysis radiation dose,tumor volume, Karnofsky performance status （KPS） are significantly associated with first follow-up response（FFR）. On multivariate analysis only the first two are significant. Prognostic factors of survival time are FFR, tumor dose and clinical stage. Conclusions SRT can significantly raise survival time expecially for phase Ⅲ patients. The dose 72 Gy for NSCLC old patients is safe.
