免疫检查点抑制剂治疗转移性胃癌疗效预测因子

摘要/Abstract

摘要：

近年来,免疫治疗被更加频繁地用于化疗后进展的转移性胃癌,其中使用最多的是免疫检查点抑制剂(ICI)。然而ICI在不同患者中的疗效差别较大,所以越来越多地开展了关于预测ICI疗效的生物标志物的研究。微卫星不稳定及EB病毒亚型是目前预测ICI治疗反应率相对确切的生物标志物;程序性死亡配体1及肿瘤突变负荷的预测作用仍存在争议;肿瘤浸润淋巴细胞、肿瘤相关巨噬细胞、纤维蛋白样蛋白1、选择性启动子以及其他一些预测因子也正在研究中。

Abstract:

In recent years, immunotherapy has been used more frequently for metastatic gastric cancer that has progressed after chemotherapy, the most commonly used of which are immune checkpoint inhibitors (ICIs). However, the efficacy of ICIs varies greatly among different patients. Therefore, more and more studies have been carried out on biomarkers that predict the efficacy of ICIs. Microsatellite instability and Epstein-Barr virus subtype are relatively accurate biomarkers indicating the response rate of ICIs treatment. The predictive roles of programmed death ligand-1 and tumor mutation burden are still controversial. Tumor infiltrating lymphocyte, tumor-associated macrophages, fibrinogen-like-protein 1, alternative promoters and other predictors are also being studied.
