Proton Radiation Therapy for Gliomas

In this research study the investigators are looking at a type of radiation called proton radiation. Proton radiation has been shown to deliver virtually no radiation beyond the area of the tumor, sparing surrounding normal tissue from exposure. This may reduce side effects that patients would normally experience with conventional radiation therapy. In this research study the investigators are looking to determine if proton radiation with a reduced field size will be as effective in controlling tumor growth as photon therapy, while reducing the treatment-related side effects observed in patients with brain tumors.
