Terms that classify grade astrocytomas (A), oligodendrogliomas (ODG), or mixed (GM). Grade III named similarly, and preceded by the word anaplastic, example, anaplastic astrocytoma (AA), oligodendroglioma (ODGA), glioma (GAM). most form, IV tumor, is designated glioblastoma GBM. GBMs diagnosed more frequently than lower astrocytomas. recent GBM classifications reflect genetic aspects involved tumor have prognostic value. important factor histopathological diagnosis of tumor. survival patients with AA much higher glioblastoma. Other factors associated age patients, Karnofsky scale, surgery, radiotherapy, chemotherapy. There evidence suggesting an association between younger longer supratentorial
