Adaptive Radiotherapy and MRIs Based on Patients With Newly Diagnosed High-Grade Glioma
Study Details
Study Description
Brief Summary
The purpose of this study is to find out if performing additional Magnetic Resonance Image (MRI) scans of the subjects' brain during each week of the radiation treatment of their high-grade glioma will help improve the radiation treatment.

Detailed Description
Diffusion weighted imaging (DWI) and Perfusion-weighted imaging (PWI) are validated MRI techniques that aid in diagnosis, prognosis, and assessment of treatment efficacy and, while they are utilized in select clinical settings, they have yet to make their way into routine clinical practice at most centers. DWI is a non-invasive MRI modality that has demonstrated an ability to predict for a response to radiation therapy in the primary treatment of patients with glioblastoma (GBM). PWI is one collection of measures that includes dynamic susceptibility contrast (DSC) enhancement and dynamic contrast-enhanced (DCE) imaging. The latter methods of MRI-adapted radiotherapy allow the opportunity to direct high-dose radiation to areas most likely to harbor resistant tumor while avoiding regions having a low likelihood of future recurrence. Multiple MRI sequences have been developed and validated that may identify high-risk areas in patients with High-grade glioma (HGG) and the ability to acquire multiple sequential time points creates an opportunity for dynamic radiotherapy that has not previously been explored. The current standard of care in radiotherapy does not incorporate any additional neuroimaging data.
This study hypothesizes that pre- and mid-treatment advanced imaging with (DWI) and (PWI) in patients with HGG can be used to generate an adaptive radiotherapy boost volume that correlates with areas of future recurrence and that this volume has a higher spatial correlation relative to the current standard of care.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Adaptive Radiotherapy Subjects will receive radiotherapy per standard of care over 30 once-daily fractions in addition to 6 brain MRIs each in every week of treatment. |
Other: Adaptive Radiotherapy
Each patient will undergo a brain MRI at the following time points:
Baseline- within 2 weeks prior to the start of chemo-RT,
Week #1- on Fractions # 4 or 5
Week #2- between Fractions # 6-10 (at least 5 days after the Week 1 MRI)
Week #3- between Fractions # 11-15 (at least 5 days after the Week 2 MRI)
Week #4- between Fractions # 16-20 gadolinium contrast (at least 5 days after the Week 3 MRI)
Week #5- on Fractions # 24 or 25 (after the start of the Conedown)
Week #6- +/- 3 days of Fraction #30 (end of RT)

Outcome Measures
Primary Outcome Measures
- Prediction of progression of disease in patients with high-grade glioma. [3 years]
To compare the volume of the current standard of care conedown volume definition with an MRI-based adaptive plan in predicting the location of disease progression in patients with high-grade glioma.
Secondary Outcome Measures
- Estimate the progression-free and overall survival in patient with high-grade glioma. [3 years]
Assess the prognostic and predictive value of highly-diffusion weighted and perfusion-weighted imaging in estimating progression-free and overall survival in patients with high-grade glioma.
