Definition

Noun: A glioma is a type of tumor that originates in the glial cells (neuroglia) of the brain or spinal cord. These tumors are named for their origin in the supportive tissue of the central nervous system.

Usage and Examples

• Noun:
  • The patient was diagnosed with a glioma after experiencing severe headaches.
  • Surgery is a common treatment for a low-grade glioma.
  • Research is focused on finding more effective therapies for malignant gliomas.

Advanced Usage

• "High-grade glioma": Refers to a fast-growing, aggressive type of glioma (e.g., glioblastoma).
  • The prognosis for a high-grade glioma is often more serious than for a low-grade one.
• "Diffuse midline glioma": A specific, aggressive type of glioma that occurs in critical midline structures of the brain.
  • Diffuse midline glioma is a challenging pediatric brain tumor.

Variants and Related Words

• Glioblastoma (n): The most common and aggressive type of malignant glioma.
  • Glioblastoma multiforme is a grade IV glioma.
• Astrocytoma (n): A glioma that arises from astrocytes, a type of glial cell.
  • An astrocytoma is a common subtype of glioma.
• Oligodendroglioma (n): A glioma that develops from oligodendrocytes, another type of glial cell.
  • Oligodendrogliomas are often slower-growing gliomas.

Synonyms

• Neuroglial tumor: A more technical term for a tumor arising from glial cells.
• Glial neoplasm: A medical term for an abnormal growth of glial cells.

Related Terms and Phrases

• "Glioma treatment": The medical management of a glioma, which may include surgery, radiation, and chemotherapy.
  • Glioma treatment plans are highly individualized.
