Brief Summary
This clinical trial studies whether T2 star (T2\*) magnetic resonance imaging (MRI) and biomarker blood testing can help predict how World Health Organization (WHO) grade IV gliomas (malignant gliomas) might change or progress over time.

Outcome Measures
Primary Outcomes (1)
Relationship between T2 (observed)-weighted imaging (T2*) magnetic resonance imaging relation time and dimeric transferrin receptor expression
Will be characterized with mixed effects regression modeling. Correlation between the two biomarkers will be estimated with the multivariate linear mixed effects regression approach of Hamlett, Ryan, and Wolfinger. Cluster bootstrapping will be employed to calculate a 95% confidence interval for their correlation and a p-value for testing its significance at the 5% level.
Up to 3 months post-radiation therapy
Secondary Outcomes (2)
Effects of T2* relaxation and/or circulating dimeric transferrin receptor on progression-free survival (PFS)
Up to 3 months post-radiation therapy
PFS
From treatment initiation to the date of first documentation of disease progression or death due to any cause in the absence of documented progression, assessed up to 3 months post-radiation therapy
Study Arms (1)
Diagnostic (T2* MRI, blood sample collection)
EXPERIMENTALPatients undergo T2\* MRI over 10 minutes and blood sample collection during radiation therapy simulation, weekly during radiation therapy, and at 1- and 3- months post-radiation therapy in the absence of unacceptable toxicity. Patients also undergo standard MRI throughout the study.
Interventions
Undergo T2\* MRI
Undergo blood sample collection
Undergo standard MRI
