简介：老年性非小细胞肺癌（NSCLC）的相对和绝对发病率均高，易合并慢性心肺疾患、糖尿病和生理功能下降，晚期肿瘤患者也易导致一般情况差，使对治疗副作用的耐受性差，影响正规的放疗、化疗与综合治疗。在早期NSCLC，立体定向或三维适形放疗能取得与手术相近的疗效，还能保证生活质量，应作为老年性和一般情况差的早期NSCLC的首选治疗手段。在局部晚期NSCLC，尽管治疗效果不一定差于年纪较小者，但综合治疗，特别是同步放化疗可能带来高的并发症，甚至治疗相关死亡。因此，应艺术性的个体化进行放化疗的综合治疗，特别是同步放化疗，适当减少照射范围、化疗剂量和选择同步方案，从而提高疗效和保证生存质量，使病人得到最大受益。
