    The prognosis is worst for these grade 4 gliomas. Few patients survive beyond 3 years. Individuals with grade 4 astrocytoma have a median survival time of 17 [6] weeks without treatment, 30 [6] weeks with radiation, and 37 [6] weeks with surgical removal of most of the tumor followed by radiation therapy. Long-term survival (at least five years ...

    The concept of grading of the tumors of the central nervous system, agreeing for such the regulation of the "progressiveness" of these neoplasias (from benign and localized tumors to malignant and infiltrating tumors), dates back to 1926 and was introduced by P. Bailey and H. Cushing, [1] in the elaboration of what turned out the first systematic classification of gliomas.

    Subependymal giant cell astrocytoma (SEGA, SGCA, or SGCT) is a low-grade astrocytic brain tumor (astrocytoma) that arises within the ventricles of the brain. [1] It is most commonly associated with tuberous sclerosis complex (TSC). Although it is a low-grade tumor, its location can potentially obstruct the ventricles and lead to hydrocephalus.

    The first tumor classified as grade I is called pilocytic astrocytoma and it is most commonly observed in children rather than adults. [2] The next tumor is never common in the Dns called diffuse astrocytoma and it is considered a grade II, they are benign, or noncancerous, but can become malignant, meaning cancerous, as the tumor progresses.

    In 2021, the fifth edition of the WHO Classification of Tumors of the Central Nervous System was released. This update eliminated the classification of secondary glioblastoma and reclassified those tumors as Astrocytoma, IDH mutant, grade 4. Only tumors that are IDH wild type are now classified as glioblastoma. [39]
