    摘要:放疗主要以局部治疗肿瘤被广泛应用于临床,它不仅可以通过损伤DNA直接杀伤肿瘤细胞,而且也对机体的免疫系统产生巨大影响。这种治疗方式不仅有抑制作用,更有激活效应。程序性死亡蛋白-1及其配体-1的抗体作为目前最热门的免疫检查点抑制剂,可通过恢复和提高机体T细胞的免疫杀伤功能抑制肿瘤的增长。随着研究的深入,人们发现二者联合应用治疗肿瘤,疗效较单一治疗模式提高。

    Abstract:Radiotherapy is widely used in local treatment of tumors. It can not only directly kill tumor cells by damaging DNA, but also have a great impact on the immune system of the body. This effect is not only inhibited, but also more activated. Programmed death1 (PD1) and its ligand 1 (PDL1) antibody, as the most popular immune checkpoint inhibitor, can inhibit tumor growth by restoring and enhancing the immune killing function of T cells. With the deepening of the study, it is found that the combination of the two treatment of tumor, the curative effect is better than the single mode.
