Abstract

脑转移是非小细胞肺癌(non-small cell lung cancer, NSCLC)的常见并发症,预后较差。近年来,免疫检查点抑制剂将恶性肿瘤的治疗带入新纪元。程序性死亡因子-1(programmed death-1, PD-1)/程序性死亡因子配体-1(programmed death ligand 1, PD-L1)抑制剂通过激活自身免疫系统,产生抗肿瘤效应。PD-1/PD-L1抑制剂在NSCLC脑转移治疗中初露锋芒,但其确切疗效及最佳治疗模式仍有待进一步研究。本文针对NSCLC脑转移灶的免疫微环境,PD-1/PD-L1抑制剂在颅内的作用机制及其临床研究现状进行综述。
