MRI Predictors of Response to Tumor Treating Fields

Patients with glioblastoma, an aggressive brain tumor, are recommended to undergo treatment with tumor treating fields using the Optune device as part of standard of care therapy. While undergoing treatment, patients are monitored regularly with brain MRI scans to look for tumor progression, but there are currently no means to predict which, or when, patients will progress. The purpose of the current study is to prospectively analyze these MRI scans to look for subtle imaging markers that can predict for future brain tumor progression while undergoing tumor treating field therapy.
