Abstract: Glioblastoma multiforme(GBM)is one of the most common primary malignant brain tumors.GBM has the characteristics of high invasiveness,high recurrence rate and low survival rate,with a poor prognosis.Programmed cell death receptor 1(PD-1)/programmed cell death ligand 1(PD-L1)as the main immune checkpoint(IC),the formation of immune pathways can trigger negative regulation of immune response and enhance the invasiveness of GBM cells in brain tissue.Research into GBM treatment is ongoing,and immune checkpoint inhibitors(ICIs)have also received considerable attention.ICIs activate antitumor response by inhibiting negative immunoregulatory pathways,providing a new therapeutic approach for GBM.Several clinical studies have focused on the combination of standard therapy(temozolomide,radiotherapy),targeted therapy,and other immunotherapies.This review describes the PD-1/PD-L1 pathways,and summarizes the research progress of PD-1/PD-L1 monotherapy,neoadjuvant therapy and combined chemotherapy,radiotherapy,targeted therapy,hormones,etc.in the treatment of GBM.

Key words: Glioblastoma, Programmed death receptor-1, Immunotherapy
