免疫疗效生物标志物在鼻咽癌治疗中的预测价值

摘要/Abstract

摘要：

免疫治疗在复发或转移鼻咽癌患者中客观缓解率达20%~30%,然而获益人群较少。程序性死亡受体-1及其配体-1高表达和(或)肿瘤突变负荷高的鼻咽癌患者,免疫治疗疗效显著;肿瘤微环境生物标志物尤其是肿瘤浸润淋巴细胞,种类丰富,在不同EB病毒状态的鼻咽癌中表达不同,可预测鼻咽癌患者的免疫治疗反应;其他免疫疗效生物标志物如错配修复缺陷在鼻咽癌中发生率较低,预测作用受限。联合检测不同种类免疫疗效预测生物标志物有助于筛选免疫治疗获益人群。

Abstract:

Immunotherapy has achieved objective response rates of 20%-30% in patients with recurrent or metastatic nasopharyngeal carcinoma, but fewer people are benefiting. Studies have shown that patients with nasopharyngeal carcinoma carrying high expression of programmed death-1/programmed death-ligand 1 and/or high tumor mutation burden have a significant response to immunotherapy. Biomarkers of the tumor microenvironment, especially tumor infiltrating lymphocyte, are abundant in nasopharyngeal carcinoma, varying from different Epstein-Barr virus states, which can also play a predictive role of immunotherapy efficacy. Other biomarkers, such as mismatch repair-deficient, have a low incidence in nasopharyngeal carcinoma and limited predictive power. Combined detection of different types of immunotherapeutic biomarkers is more helpful to identify suitable populations for immunotherapy.
