PRIMARY OBJECTIVES: I. To determine the feasibility of using spectroscopic MRI (sMRI) to guide dose-escalated radiation therapy (RT) for newly-diagnosed glioblastoma (GBM)s. II. To determine the safety of using sMRI to guide dose-escalated RT for newly-diagnosed GBMs. SECONDARY OBJECTIVE: I. To determine whether the progression free survival at 1 year with sMRI-guided, dose-escalated RT is improved for newly-diagnosed GBMs. TERTIARY OBJECTIVES: I. To determine whether sMRI-guided, dose-escalated RT increases the overall survival of patients with newly diagnosed GBMs. II. To determine whether sMRI data obtained after initiation of therapy (at 2 weeks after RT/TMZ start and prior to cycle 1 and 5 of adjuvant temozolomide [TMZ]) will provide early evidence of GBM progression not seen on standard MRIs. III. To determine whether performance on neurocognitive and quality-of-life (QOL) assessments in newly-diagnosed GBM patients treated with sMRI-guided, dose-escalated RT differ from historical controls. OUTLINE: Patients undergo sMRI-guided radiation therapy daily for the first 5 days of every week (Monday - Friday) over 6 weeks. Patients also receive standard of care temozolomide orally (PO) daily during radiation therapy for up to 42 days. After completion of study treatment, patients are followed up every 3 months for up to 2 years and then periodically.
