免疫检查点抑制剂联合放疗在晚期非小细胞肺癌的研究进展

白 心宇, 张 力

摘要

近年来,免疫检查点抑制剂(immune checkpoint inhibitors,ICIs)的探索取得了实质性进展,
并改变了晚期非小细胞肺癌(non-samll cell llung cancer,NSCLC)治疗的模式,但免疫单药治疗的获益人群
有限。放疗 (radiotherapy,RT) 作为局部治疗因其耐受性较好、效果显著等特点广泛应用于癌症患者的治疗。
有研究发现放疗可以通过提高肿瘤免疫原性、重塑肿瘤免疫微环境的途径激活抗肿瘤免疫。目前,越来越多
的证据表明 RT 和 ICIs 之间存在协同作用。如何充分发挥放疗联合免疫治疗(immunotherapy combined with
radiotherapy,iRT)的协同作用,提高晚期非小细胞肺癌患者的治疗效果 , 带来良好的预后 , 是肿瘤治疗领域亟
待解决的热点问题。本文将对 iRT 在晚期 NSCLC 中的作用机制及临床研究进展等方面进行综述,为未来临床
iRT 的选择提供参考。
