7 Φεβ 2023 · Gliomas are classified into four grades (I, II, III, and IV), and the treatment and prognosis depend upon the tumor grade. Grade I or II tumors are termed low-grade gliomas. The term malignant or high-grade glioma refers to tumors that are classified as:

GBM carries the worst prognosis, while pure oligodendroglioma has a protracted natural history and better outcome, and excellent response to therapy. Prognosis of mixed anaplastic oligoastrocytoma and anaplastic astrocytoma is intermediate between GBM and pure anaplastic oligodendroglioma.
Learn about high-grade gliomas, fast-growing brain or spinal cord tumors that affect children and adults. Find out how they are diagnosed, treated and what factors affect their outlook.
Grade III and IV glioma, anaplastic astrocytoma (AA), anaplastic oligodendroglioma (AO), mixed anaplastic oligoastrocytoma (AOA) and glioblastoma (GBM), were known as high-grade glioma (HGG), which carried poor prognosis despite intensive treatments with surgery, radiotherapy, and chemotherapy.
Diffuse gliomas represent a spectrum of disease, ranging from a low-grade chronic condition with a prognosis measured in years, to a high-grade, devastating diagnosis with a prognosis of short months. Treatment is usually multimodal, requiring surgery, radiotherapy and chemotherapy at various stages.
28 Μαρ 2023 · High-grade gliomas (World Health Organization grades III and IV) are the most frequent and fatal brain tumors, with median overall survivals of 24–72 and 14–16 months, respectively. We reviewed the progress in the diagnosis and prognosis of high-grade gliomas published in the second half of 2021.
4 Αυγ 2023 · Whereas the prognosis for GB is grim (5-year survival rate of 5–10%) outcomes for the other high-grade gliomas are typically better, depending on the molecular features of the tumor. The presence of neurological deficits and seizures can significantly impact quality of life.
