OBJECTIVES:
* Determine the magnetic resonance spectroscopic imaging (MRSI) characteristics of patients who are undergoing treatment for supratentorial glioma.
* Determine the survival of patients who undergo magnetic resonance imaging and MRSI.
* Determine the clinical outcome of patients who undergo these imaging procedures.
* Correlate measures of metabolic tumor burden (i.e., CNI, CCCrI, CrNI, and LLI) with survival and clinical outcome in patients who undergo these imaging procedures.
* Determine the time to clinical progression in patients who undergo these imaging procedures.
OUTLINE: Patients are assigned to 1 of 2 treatment groups based on grade of disease.
* Group 1 (patients with grade II glioma): Patients undergo magnetic resonance imaging (MRI) and magnetic resonance spectroscopic imaging (MRSI). Patients then receive chemotherapy. Patients undergo repeat MRI/MRSI after courses 2 and 4 of chemotherapy.
* Group 2 (patients with grade III-IV glioma): Patients undergo MRI/MRSI and then undergo surgical resection of the tumor. Patients then receive chemoradiotherapy. Patients undergo repeat MRI/MRSI within 2 weeks and at 2 months after completion of radiotherapy.
Patients are followed for recurrence, disease progression, and survival.
PROJECTED ACCRUAL: A total of 250 patients will be accrued for this study.
