Tumor mutational burden (TMB) is an emerging biomarker for the prediction of immunotherapy success in solid tumors. Gliomas, however, do not demonstrate a correlation between TMB and immunotherapy efficacy. Here, we discuss the potential factors influencing this discordance, focusing on the impact of neoantigen immunogenicity, clonality, expression, and presentation.
Keywords: gliomas; immunotherapy; neoantigens; tumor mutational burden.
