Brain Cancer – Gliomas, Version 1.2016

What are gliomas?

They are cancers of glial cells. Glial cells support nerve cells in the brain and spine.

10

Oligodendrogliomas derive from glial cells called

oligodendrocytes. Oligoastrocytomas

are

a mixed-cell subtype of glioma.

14

What are the treatment options for grade II oligodendrogliomas

and oligoastrocytomas?

Surgery is often used to confirm the presence of and to treat grade II gliomas. MRI is often

needed to assess how much of the cancer was removed.

49

More treatment is often received after surgery. Only tumors that were fully removed or

those with stable or no symptoms may be observed rather than treated. If more treatment

is needed, radiation therapy, chemotherapy, or both may be received.

49

MRI scans are needed on a regular basis to track treatment results.

50

If a grade II glioma returns, surgery may be an option. After surgery or instead of, you

may receive radiation therapy, chemotherapy, or both if you weren’t treated with radiation

before. If you had radiation before, chemotherapy should follow surgery or may be the

sole treatment if surgery isn’t an option.
