Prognostic Value of Programmed Death Ligand 1 (Pd-L1) in Glioblastoma: A Systematic Review, Meta-Analysis and Validation Based on Dataset

Analysis of a dataset verified the prognostic value of PD-L1 and revealed an association between PD-L1 mRNA expression and the status of isocitrate dehydrogenase. Increased PD-L1 expression predicts unfavorable overall survival in glioblastoma.
