Study Details

Brief summary:

A biomarker is a measurable indicator of the severity or presence of some disease state. In this study, brain metastases patients who will be receiving radiation treatment, will undergo CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) scans prior to and after radiation treatment to measure these biomarkers. This is a single-center phase II study to validate the predictive abilities of biomarkers, in terms of determining how patients will respond to radiation treatment.

Interventions and Outcome Measures

Arms

other: CT and MRI Scans

Each patient will undergo a 3T MRI scan as well as a dynamic contrast-enhanced CT scan within one week prior to the start of treatment. Patients will also undergo a research 3T MRI scan and research dynamic contrast-enhanced CT scan at the one week post radiotherapy mark. An MRI scan during their 3 month post-treatment follow up visits will take place as per routine standard of care.

Interventions

CT and MRI Scans

CT and MRI scans will occur before and after radiation therapy.

Primary outcome measure

  • Response Assessment in Neuro-Oncology (RANO) to validate biomarkers [ Time Frame: Up to 2 years. ]
  • Response Evaluation Criteria in Solid Tumors (RECIST) criteria to validate biomarkers [ Time Frame: Up to 2 years. ]
  • Progression Free Survival (PFS) to validate biomarkers [ Time Frame: Up to 2 years. ]
