非小细胞肺癌免疫治疗中外周血生物标志物的研究进展

王 誉晓, 蔡 春玉

摘要

非小细胞肺癌(non-small cell lung cancer,NSCLC)是全球最常见且致死率最高的恶性肿瘤,随着免疫检查点抑制剂(immune checkpoint inhibitors,ICIs)的引入,其治疗模式经历了革命性的改变。然而,并不是所有患者都能够从ICIs治疗中受益,这主要依赖于组织中程序性死亡受体配体1(programmed cell death ligand 1,PD-L1)的表达情况。PD-L1和肿瘤突变负荷(tumor mutational burden,TMB)作为目前临床上普遍认可的生物标志物,用于筛选ICIs获益的患者群体。但由于其依赖于活检样本,无法满足临床对ICIs疗效评估的需求。而基于血液的生物标志物,提供了一种微创的方式来动态监测NSCLC患者的疗效,补充了组织生物标志物的不足。本文将综述非小细胞肺癌免疫治疗中外周血生物标志物的研究进展。
