Gliomas
Key Points
Gliomas are primary tumors that originate in brain parenchyma; they include astrocytomas, oligodendrogliomas, and ependymomas. Gliomas vary in location, degree of malignancy, treatment, and prognosis. For most gliomas, surgically excise as much tumor as possible (gross total resection) without unduly damaging areas of eloquent brain, then follow with radiation therapy and/or chemotherapy.
