Observation or Radiation Therapy in Treating Patients with Newly Diagnosed Grade II Meningioma that has been Completely Removed by Surgery

This randomized phase III trial studies how well radiation therapy works compared with observation in treating patients with newly diagnosed grade II meningioma that has been completely removed by surgery. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors.

In order to participate you must meet the following criteria:

• Have a newly diagnosed unifocal intracranial meningioma, gross totally resected, and histologically confirmed as WHO grade II based upon pathology findings at the enrolling institution.
• Are registered within 180 days of the initial surgery.
• Are 18 years of age or older.
• Have not received previous radiotherapy to the scalp, cranium, brain, or skull base.
