Glioblastoma

Most aggressive primary brain tumor; IDH-wildtype GBM has EGFRvIII amplification (~40%), PTEN loss (~30%), and TERT promoter mutations. Temozolomide + radiotherapy is standard; tumor-treating fields (TTFields) improve OS; MGMT promoter methylation predicts temozolomide benefit.

Also known as: GBM, glioblastoma multiforme, WHO grade 4 glioma, IDH-wildtype glioblastoma, GBM IDH-wt, high-grade glioma
