Summary
The purpose of this study is to determine the best radiation dose for participants with meningioma that has grown back after previous surgery, or which the surgeon has been unable to remove completely. This research study is designed to determine whether a higher dose of radiation will decrease the likelihood that the tumor will grow back, compared to the probability of re-growth that occurs after standard radiation doses.
