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.
