Prediction of Response of Brain Metastases to Brain Irradiation Using Voxel Based Diffusion Tensor Imaging

This pilot clinical trial studies how well voxel based diffusion tensor imaging in
predicting response in patients with brain metastases undergoing whole-brain radiation
therapy or stereotactic radiosurgery. Voxel based diffusion tensor imaging (VB-DTI) may
allow doctors to measure response to whole brain radiation therapy or stereotactic
radiosurgery earlier than is possible with a standard magnetic resonance imaging. The
earlier ability to measure response may allow for consideration of alternative therapies at
an earlier stage.

PRIMARY OBJECTIVES:

I. To determine if voxel based diffusion tensor imaging will provide an early predictive
assessment of therapy response, as compared to radiographic volumetric response criteria.

OUTLINE:

Patients undergoing whole-brain radiation therapy (WBRT) for a total of 10 fractions also
undergo VB-DTI magnetic resonance imaging (MRI) at baseline, 1 week after WBRT initiation,
and 7-11 days after completion of WBRT. Patients undergoing stereotactic radiosurgery (SRS)
without WBRT also undergo VB-DTI MRI at baseline and 7-11 days after completion of SRS.

After completion of study, patients are followed up every 2 months for 6 months and then
every 6 months until death.

Inclusion Criteria:

- Patients with multiple lesions from solid tumors on clinical MRI diagnosing the brain
metastases may be treated with either WBRT or SRS if clinically indicated at the time
of presentation but not both

- Karnofsky performance status (KPS) >= 70

- Patients presenting with brain metastases from a newly diagnosed cancer may have
systemic disease (brain disease at the time of initial cancer diagnosis)

- Patients with a history of cancer, but newly diagnosed brain metastases must have
clinically stable systemic disease

- If a biopsy is performed, the patient has to be at least 1 week post-biopsy

- The patient must be able to commit to diffusion-weighted magnetic resonance (MR)
imaging, diffusion tensor imaging (DTI), and chemical shift imaging (CSI) prior to
treatment, after the first week of treatment, and 7-11 days after the completion of
treatment at the Magnetic Resonance Research Center (MRRC)

- Patients undergoing SRS without WBRT must be able to commit to diffusion-weighted MR
imaging, DTI, and CSI prior to treatment, and 7-11 days after the completion of the
SRS treatment at the MRRC

- The patient must also be able to commit to post-treatment follow-up visits at
Montefiore Medical Center involving serial MR imaging; the follow-up visits are to
occur bimonthly for 6 months and then every 6 months until death

Exclusion Criteria:

- Any medical condition, which would make the imaging studies or WBRT unsafe or poorly
tolerated

- Patient is receiving concurrent chemotherapy

- Known allergic reaction to contrast or shellfish

- Patients with brain metastases to be treated with radiosurgery

- Patients with brain metastasis resulting from hematologic malignancies and small cell
lung cancer

- Implanted metal devices or foreign bodies that serve as a contraindication to MR
imaging

- Creatinine > 1.4 mg/dl and creatinine clearance < 20 mg/dl

- Uncontrolled, clinically significant cardiac arrhythmias

- Severe claustrophobia

- Pregnant female

- Any prior radiation therapy to the brain

- KPS < 70

- Patients with leptomeningeal disease
