摘要: 确定预测PD-1/PD-L1通路阻断治疗临床反应的生物标志物有助于患者筛查和个体化治疗。研究证明治疗前肿瘤组织中肿瘤细胞和肿瘤浸润淋巴细胞PDL1的高表达,肿瘤间CD8+T细胞的大量浸润以及肿瘤细胞基因高突变负荷的患者阻断PD-1/PD-L1通路治疗的临床疗效更明显,这些生物标志物有望成为筛查肿瘤患者的指标。

Abstract: Identifying biomarkers predicting clinical response to treatment of PD1/PDL1 pathway blockade can guide patient selection and therapeutic individualization. Some researches have shown that patients with cancer will acquire better clinical effects by blocking PD-1/PD-L1 pathway whose characteristics include higher pretreatment expression of PD-L1 by tumor cells or tumor infiltrating immune cells, the massive infiltration of intratumoral CD8+ T cells, the high mutation frequency of tumor cell gene. These biomarkers are expected to become indicators which can select patients.
