摘要:

免疫检查点抑制剂成为近年来肿瘤治疗的热点,越来越多的肿瘤患者从免疫治疗中获益。由于免疫治疗费用较高,未检测人群免疫治疗获益率仅为20%。因此,精准地选择预测性生物标志物对于肿瘤患者个体化免疫治疗至关重要。反映肿瘤免疫微环境和肿瘤细胞内在特征的生物标志物,如程序性死亡蛋白1(PD-1)及其配体PD-L1、肿瘤突变负荷、微卫星不稳定性等,均已被证实与抗PD-1/PD-L1治疗效果相关。同时,基于组织和血清的标志物层出不穷,如何真正实现精确的肿瘤免疫治疗仍有待进一步临床研究。

Abstract:

Immonocheckpoint inhabitors have become the focus of tumor therapy in recent years, and more and more tumor patients benefit from immunotherapy. Due to the high cost of immunotherapy, the benefit rate of immunotherapy for untested population is only 20%. Therefore, accurate selection of predictive biomarkers is crucial for individualized immunotherapy of tumor patients. Biomarkers reflecting tumor immune microenvironment and tumor cell intrinsic features, such as programmed death-1 (PD-1) and its ligand PD-L1, tumor mutational burden and microsatellite instability, have been proved to associate with treatment effect of anti-PD-1/anti-PD-L1 therapy. At the same time, markers based on tissue and serum emerge in endlessly. How to truly achieve accurate immunotherapy for tumor needs further clinical research.
