A landmark NATO summit in Chicago endorsed an exit strategy that calls for handing control of Afghanistan to its own security forces by the middle of next year but left questions unanswered about how to prevent a slide into chaos and a Taliban resurgence after allied troops are gone.

FACTBOX: Gliomas are hard to treat

WASHINGTON | Tue May 20, 2008 2:42pm EDT

WASHINGTON (Reuters) - Sen. Edward Kennedy, a Massachusetts Democrat who outlived two assassinated brothers to become an elder statesman, has a brain tumor known as a glioma, his doctors said on Tuesday.

Here are a few facts about gliomas:

- Gliomas arise from brain cells known as glial cells, which are different from the better-known neurons.

- They can be high-grade, which are more dangerous, or low-grade, which are often slow-growing and require little or no treatment.

- The American Cancer Society estimates that 21,000 Americans a year are diagnosed with brain tumors. About 40 percent of these are gliomas.

- Brain tumors can be surgically removed but they are often difficult to reach for treatment. Some chemotherapy drugs can reach into the brain to attack tumor cells. Radiation therapy is also used to treat glioma.

- There are several types of glioma, including astrocytomas, ependymomas, glioblastoma multiforme, ologodendrogliomas and mixed gliomas. They are named according to the specific type of brain cell affected.
