This fact sheet provides a brief overview of glioma tumors. Please see Brain Tumors: An Introduction for more information. A glioma is a type of brain tumor that grows from glial cells. Glial cells support nerve cells with energy and nutrients and help maintain the blood-brain barrier. There are various types of glial cells, each with a different function:. Astrocyte - transports nutrients and holds neurons in place Oligodendrocyte - provides insulation myelin to neurons Microglia - digests dead neurons and pathogens Ependymal cells - line the ventricles and secrete cerebrospinal fluid.

GBMs are high-grade astrocytomas; they are therefore generally aggressive, largely resistant to therapy, and have a corresponding poor prognosis. They have a predilection for spreading along the condensed white matter tracts such as corticospinal tracts and corpus callosum to involve the contralateral hemisphere. Glioblastoma was previously known as glioblastoma multiforme; the multiform refers to the tumor heterogeneity. Somewhat confusingly the abbreviation GBM is still considered appropriate Primary glioblastomas are those that arise de novo, without a pre-existing lower grade diffuse astrocytoma. Primary glioblastomas are almost invariably IDH wild-type.

These manuscripts contain updated topics with a major clinical or conceptual relevance in modern medicine. The journal adheres to the standards of academic research publications in all aspects including peer-review and ethical principles. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two receding years. CiteScore measures average citations received per document published.
It is published every 2 months 6 issues per year. All manuscripts are submitted for review by experts in the field peer review and are carried out anonymously double blind. The Journal accepts works written in Spanish or English.
