Magnetic Resonance Imaging in Determining Extent of Cancer in Patients With Newly Diagnosed Glioma

January 7, 2013 updated by: Jonsson Comprehensive Cancer Center

Magnetic Resonance Correlates of Glioma Tumor Burden

RATIONALE: New imaging procedures such as magnetic resonance imaging may improve the ability to detect the extent of newly diagnosed cancer.

PURPOSE: Diagnostic study of magnetic resonance imaging to determining the extent of cancer in patients who have newly diagnosed glioma.

Detailed Description

OBJECTIVES: I. Determine whether proton magnetic resonance spectroscopic imaging (1H-MRSI) and diffusion magnetic resonance imaging (DI) measures of glioma cell burden correlate with histopathologically measured cell counts in glioma patients who are scheduled to undergo surgical resection. II. Determine whether 1H-MRSI and DI measures of glioma cell burden are invariant over the short term (1 week) as steroid dose is increased in these patients.

OUTLINE: Part I: Patients who are scheduled to have surgical resection of brain tumor undergo conventional magnetic resonance imaging (MRI), proton magnetic resonance spectroscopic imaging (1H-MRSI), and diffusion magnetic resonance imaging (DI) within 1 week before resection. Patients undergo conventional MRI within 72 hours after completion of surgical resection. Image characteristics of the resected tissue are correlated with histopathological measures. Part II: Patients who have clinical indications for increasing the dexamethasone dose are treated on part II of the study. Patients are stratified by status of steroid treatment (steroid naive vs prior steroid management). Patients undergo conventional MRI, 1H-MRSI, and DI within 2 days before and within 4-7 days after increasing the dexamethasone dose. Image characteristics on films taken before and after increasing the dexamethasone dose are compared.

PROJECTED ACCRUAL: A total of 75 patients will be accrued for part I of the study and a total 40 patients (20 per stratum) will be accrued for part II of the study within 4 years.
