WebGlioblastoma (GBM) Glioblastomas (also called GBM) are malignant (cancerous) grade 4 tumors. The tumor is predominantly made up of abnormal astrocytic cells, but also contains a mix of different cell types (including blood vessels) and areas of dead cells (necrosis). Glioblastomas are diffusely infiltrative and invade nearby regions of the brain. WebThe AAIR of cerebellar GBMs increased according to CCR (APC +11.9%, P < 0.001). The AAIR of all gliomas, which includes all anatomical subsites, decreased (-0.5% to -0.8% APC, P ≤ 0.034).
