Spots Global Cancer Trial Database for MRI Scans in Evaluating the Effects of Radiation Therapy and Chemotherapy in Patients With Newly Diagnosed Glioblastoma Multiforme or Anaplastic Glioma

Study Description

Brief Summary: RATIONALE: Diagnostic procedures, such as MRI, may help in learning how well radiation therapy and chemotherapy work in killing tumor cells and allow doctors to plan better treatment. PURPOSE: This clinical trial is studying MRI scans to see how well they evaluate the effects of radiation therapy and chemotherapy in patients with newly diagnosed glioblastoma multiforme or anaplastic glioma.

Detailed Description: OBJECTIVES: Primary * To quantitatively compare the relative cerebral blood volume/flow, mean transit time, and mean vessel diameter as measured by perfusion-weighted MRI before, during, and after chemoradiotherapy in patients with newly diagnosed glioblastoma multiforme. * To measure the permeability-surface area product on a voxel-by-voxel basis before, during, and after chemoradiotherapy in these patients. * To measure the full water self-diffusion tensor on a voxel-by-voxel basis before, during, and after chemoradiotherapy in these patients. * To compare the tensor fractional anisotropy before, during, and after chemoradiotherapy in these patients. * To compare the relative regional concentrations of choline, N-acetyl-asparate, and myoinositol as measured by magnetic resonance spectroscopy before, during, and after chemoradiotherapy to interrogate cell membrane turnover, neuronal integrity, and glial reactions. * To test the affects of a short period of 100% oxygen inhalation on imaging of tumor and surrounding tissue regions of interest, specifically cerebral blood volume changes in each area as compared to room air. Secondary * To collect blood and urine samples for correlation analysis between imaging changes, molecular markers (including genetic markers), and clinical outcome of glioblastoma multiforme (phenotypic information). * To correlate blood and urine biomarkers and blood genetic markers with tumor expression of these markers. OUTLINE: Patients undergo radiotherapy once daily 5 days a week for 6 weeks. Patients also receive oral temozolomide once daily 7 days a week during radiotherapy. After completion of chemoradiotherapy, patients receive oral temozolomide once daily for 5 days. Treatment with temozolomide repeats every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo MRI, including perfusion- and diffusion-weighted MRI, diffusion tensor imaging, and magnetic resonance spectroscopy prior to initiation of chemoradiotherapy, once weekly during chemoradiotherapy, and then monthly until tumor progression or until completion of 6 courses of post chemoradiotherapy. After completion of study treatment, patients are followed annually.
