Immunotherapies can stimulate the immune system to find, attack, and eliminate cancer cells. While tumor-associated macrophages are the most abundant immune cell population, there is reduced T lymphocyte infiltration. DMG consists of a largely immunologically cold tumor microenvironment that lacks immune cell infiltration, immunosuppressive factors, and immune surveillance.

Mouse models that recapitulate human DMG have been used to study key driver mutations and the tumor microenvironment. Histological artifacts include pseudopalisading necrosis and vascular endothelial proliferation. Mutations of H3K27M, TP53, and ACVR1 drive DMG tumorigenesis.
DMGs are characterized by unique phenotypic heterogeneity and histological features.
Due to their diffuse nature in critical areas of the brain, the prognosis of DMG remains dismal. While radiotherapy and chemotherapy are the most common treatments, these modalities have limited promise.
