T2 Star Magnetic Resonance Imaging and Biomarker Blood Testing to Predict the Change and Progress of Malignant Gliomas

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. WHO grade IV gliomas are the most common primary brain tumors. Despite aggressive standard of care treatment, overall survival remains low. Early identification of whether the glioma comes back after a period of improvement (recurrence) remains an important part of treatment management. Early identification of recurrence can be complicated as treatment effects can cause inflammation, making it difficult to identify recurrence on standard MRI. It has been shown that WHO grade IV gliomas have increased iron content and that as the glioma is treated, markers in the blood that represent iron related cell death (biomarkers) increase. T2\* mapping is an MRI technique routinely used to assess iron content within tissues and may help identify recurrence of the glioma on the MRI. The biomarker blood test in this study checks the levels of iron-related cell death biomarkers in the blood, which may help predict how well patients are responding to treatment. T2\* MRI and biomarker blood testing may be an effective way to predict how malignant gliomas might change or progress over time.

• Effects of T2* relaxation and/or circulating dimeric transferrin receptor on progression-free survival (PFS) [Срок оценки: Up to 3 months post-radiation therapy]
• PFS [Срок оценки: 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]
