摘要 不同于传统的手术、放化疗等治疗手段,免疫治疗是进展期胃癌一种新的治疗方法。随着胃癌的综合治疗进入分子时代,胃癌相关的临床研究中以PD-1/PD-L1单抗为代表的免疫治疗正在积极开展并有不错的结果。癌症基因组图谱(TCGA)分型中微卫星不稳定型胃癌和EB病毒阳性型胃癌患者均是免疫治疗的潜在获益人群。错配修复功能缺陷、高度微卫星不稳定性的肿瘤往往具有高突变表型,肿瘤浸润淋巴细胞较多。EB病毒阳性型胃癌肿瘤免疫微环境中存在大量淋巴细胞浸润,对免疫治疗反应佳,预后较好。胃癌免疫微环境中的免疫细胞、体液因子相互作用,构成复杂的肿瘤免疫微环境群落,影响肿瘤进展和生存。本文主要就胃癌免疫治疗相关生物标志物检测及应用现状展开综述,探讨其面临的问题、挑战及发展趋势,以期开发更多的联合评估模式精准指导免疫治疗。
