This week our team will be discussing malignant gliomas, one of the most
common primary brain tumor diagnoses. Gliomas arise from glial tissue
which serves to protect and nourish the brain. “Glia” is Greek and
translates to “glue.”
About one third of all primary
brain and other nervous system tumors form from glial cells. The higher
the tumor grade, the more aggressive the tumor is. Grade III and IV
tumors are considered high-grade or malignant tumors. Gliomas account
for about 80% of all primary malignant brain tumors.
Types of glioma tumors include astrocytomas, oligoastrocytomas,
oligodendrogliomas, mixed gliomas, and ependymomas. Anaplastic
astrocytomas and glioblastomas are the most commonly diagnosed types of
malignant gliomas.
While there is no cure for malignant
gliomas, current research shows promise towards understanding of the
tumor biology and identifying specific targets within the tumor that may
result in improved tumor control.
Have you or your loved one been affected by a malignant glioma? Stay tuned for more information and resources this week.
