Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This phase II trial studies how well hypofractionated proton or photon radiation therapy works in treating patients with brain tumors. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells. A shorter duration of radiation treatment may avoid some of the delayed side effects of radiation while providing a more convenient treatment and reducing costs.
