Arterial Spin Labeling Blood Flow MRI for Evaluation of Response to Antiangiogenic and Targeted Therapies of Renal Cell Carcinoma (RCC)

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess magnetic resonance imaging (MRI) as a tool to track tumor growth for renal cell carcinoma while the participant is receiving clinical treatment therapy with sunitinib or pazopanib. An MRI is a sophisticated type of scan that uses powerful magnets to make clearer images or to focus on detailed medical information in the participants abdomen and pelvis. This imaging done for this study will use the ASL MRI technique that allows us to see blood flow changes which possibly may indicated tumor growth.

Detailed Description
-----------------
MRI's will be performed at specific time points during the participants treatment for renal cell carcinoma with the drug sunitinib or pazopanib. These ASL MRI's will be performed at baseline, 2 weeks upon initiation of therapy with sunitinib/pazopanib, after cycle 2 and/or cycle 4 of therapy, and at the end of therapy. The MRI tests for all participants will be done at Beth Israel Deaconess Medical Center.

Eligibility Criteria
-----------------
Inclusion Criteria: Patients diagnosed with metastatic renal cell carcinoma and who will initiate sunitinib or pazopanib Enrolled on protocol 06-105, Collection of specimens and clinical data from patients with renal cell carcinoma treated with targeted therapies, or receiving Pazopanib as part of routine clinical care.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To explore the association of baseline blood flow in renal cell carcinoma measured by ASL MRI and tumor response to treatment with sunitinib or pazopanib |  | 2 years | 
| To explore the association of changes in tumor blood flow that occur early in the course of therapy compared to baseline and response of RCC to treatment with sunitinib or pazopanib |  | 2 years | 
| To evaluate the association between canges in tumor blood flow on ASL over the course of therapy and at the time of disease progression and resistance to therapy |  | 3 years |
