Clinical Trial – Radiation Therapy Plus Hyperbaric Oxygen in Treating Patients With Newly Diagnosed Glioblastoma Multiforme

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Hyperbaric oxygen
may increase the effectiveness of radiation therapy. Combining hyperbaric oxygen with
radiation therapy may be an effective treatment for glioblastoma multiforme.

PURPOSE: Phase I/II trial to study the effectiveness of combining radiation therapy with
hyperbaric oxygen in treating patients who have newly diagnosed glioblastoma multiforme.
