3T MRI Biomarkers of Glioma Treatment Response

Status Terminated

Clinical Trial Summary

This pilot clinical trial studies advanced magnetic resonance imaging (MRI) techniques in measuring treatment response in patients with high-grade glioma. New diagnostic procedures, such as advanced MRI techniques at 3 Tesla, may be more effective than standard MRI in measuring treatment response in patients receiving treatment for high-grade gliomas.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To correlate treatment-induced changes in quantitative MRI-based biomarkers—specifically, those sensitive to tumor protein content (amide proton transfer asymmetry [APTasym] from chemical exchange saturation transfer [CEST]), cellularity (apparent diffusion coefficient [ADC] from diffusion-weighted imaging [DWI]), and blood flow (volume transfer constant [K^trans] from dynamic contrast-enhanced [DCE]; cerebral blood flow [CBF] from dynamic susceptibility contrast [DSC])—with treatment-induced changes in tumor size, measured via standard anatomic MRI.

II. To correlate treatment-induced changes in the above quantitative MRI endpoints with patient progression-free survival (PFS).

OUTLINE:

Patients undergo measurement of tumor protein content using CEST-MRI, cellularity using DWI-MRI, and blood flow using DCE-MRI and DSC-MRI within 2 weeks of treatment and at 2 and 4 weeks after initiation of treatment. ;
