Glioma synonyms

Glioma is a broad term for a group of tumors that originate from glial cells in the brain or spinal cord; while often used as a catch-all, it encompasses specific subtypes like astrocytoma, oligodendroglioma, and ependymoma. Clinicians typically prefer the specific World Health Organization (WHO) classification based on histology and molecular markers rather than the general term glioma.

What are the common synonyms and clinical terms for glioma?

While glioma is the standard medical term, patients may encounter various synonyms depending on the specific location or cell type of the tumor. Historically, older literature may refer to these as "neuroepithelial tumors." In clinical practice, you will rarely see just the word glioma on a pathology report; instead, you will see a more precise diagnosis reflecting current WHO classifications, which categorize these tumors based on their molecular profile and cellular origin.

Why are there multiple names for glioma?

The naming of glioma has evolved significantly due to advances in molecular genetics. Historically, clinicians classified tumors solely by how they looked under a microscope. Today, researchers understand that the biology of a glioma—such as IDH mutation status or 1p/19q codeletion—is more important for prognosis and treatment than just its visual appearance. This shift from morphological to molecular classification explains why older medical records may use different terminology than modern reports.

How are gliomas classified in medical systems?

Official medical classification systems use specific codes to track glioma cases globally. These systems help researchers and clinicians standardize care:

• ICD-10/ICD-11: Uses specific codes (e.g., C71) to categorize malignant neoplasms of the brain.


• WHO Classification of Tumors of the Central Nervous System: The gold standard for defining specific glioma subtypes.


• Orphanet: Lists various rare glial tumor types under the broader category of central nervous system neoplasms.


• OMIM: Tracks the genetic predispositions associated with certain inherited forms of glioma.

Next steps

• Request a copy of your pathology report to identify the specific molecular subtype of your glioma.


• Consult a neuro-oncologist to discuss how your specific tumor classification impacts your treatment plan.
