Abstract
晚期胃癌预后较差,传统化疗疗效有限,未能满足患者治疗需求.免疫检查点抑制剂(immune checkpoint inhibitors,ICIs)已改变晚期胃癌治疗格局,其中程序性死亡受体-1(programmeddeath-1,PD-1)抑制剂联合化疗、PD-1抑制剂联合曲妥珠单抗及化疗已分别成为人表皮生长因子受体2(human epidermal growth factor receptor 2,HER-2)阴性或阳性晚期胃癌一线治疗选择,其他免疫检查点分子抑制剂和癌症疫苗、过继性细胞输注等疗法的研究均在进行中.如何通过生物标志物筛选免疫治疗最佳获益人群,是近期研究热点.除肿瘤突变负荷、程序性死亡配体-1(programmeddeath-ligand1,PD-L1)表达、微卫星不稳定性等,新兴标志物如循环肿瘤DNA、肠道微生物组学和细胞因子等均值得关注.本文就晚期胃癌一线免疫治疗的临床研究进展及展望进行综述.
