High-grade gliomas are malignant, often rapidly progressive brain tumors that are divided into anaplastic gliomas (anaplastic astrocytoma, anaplastic oligodendroglioma, and anaplastic oligoastrocytoma) and glioblastoma (GBM) based upon their histopathologic features [1]. (See "Classification and pathologic diagnosis of gliomas", section on 'Histopathologic and molecular classification'.)

The clinical manifestations, prognostic factors, and initial surgical approach to patients with high-grade gliomas will be reviewed here.

Other patient management topics that are covered separately include:

The diagnostic approach to patients with suspected brain tumors (see "Overview of the clinical features and diagnosis of brain tumors in adults")

Adjuvant radiation therapy and chemotherapy following initial surgery (see "Radiation therapy for high-grade gliomas" and "Initial postoperative therapy for glioblastoma and anaplastic astrocytoma")
