Measurement of Pro-angiogenic Markers in Patients With Hepatic Metastases Undergoing SIRT

Study Overview
=================
Brief Summary
-----------------
This study is being done to investigate the influence of giving radiation to the liver on tumors involving the liver. Investigator is specifically looking at this effect on the blood vessels within the tumor. This effect will be measured by studying substances in the blood that the tumors produce and that cause blood vessels to grow. The effects seen on these substances may help design other treatments to improve the results of the radiation used to treat these tumors.

Detailed Description
-----------------
Subjects are invited to participate in this study that have undergone a procedure as their standard of care. This procedure is known as Selective Internal Radiation Therapy (SIRT), a procedure designed for the treatment of cancer in the liver. This includes cancer that has started in the liver as well as cancer that has spread to the liver. The purpose of the study is to collect blood samples to assess for biological markers, or substances within the blood that may promote cancer growth by causing new blood vessels to form. This study will also use a new method of analyzing medical imaging (CT scan, PET scan) to try and better understand how cancer in the liver forms new blood vessels. SIRT is standard therapy and not part of this study. This study involves blood draws only.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| liver cancer<br>Patients referred for SIRT will be considered for this investigation. These patients will predominantly have stage IV colorectal metastases with liver dominant metastases or hepatocellular carcinoma. A team of oncologists, interventional radiologists, radiation oncologists and oncologic surgeons will determine that the patients are not candidates for surgical resection or ablative therapy. The patients will then be screened to confirm the patient's eligibility to receive standard of care SIRT treatment. SIRT treatment and imaging studies included in this investigation are standard of care for the patients' liver dominant disease. | |

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cellular and peptide pro-angiogenic markers in patients with hepatic malignancy before and after SIRT | Primary objective is to develop assays for both cellular and peptide pro-angiogenic markers and determine variability of these makers in patients with hepatic malignancy before and after Selective Internal Radiation Therapy (SIRT). | Depending on subject's treatment schedule blood samples are drawn from Day 0 through Day 120 (120 days for whole liver treatment). | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Imaging based predictors | To begin to develop imaging based predictors of response to SIRT. | Depending on subject's treatment schedule blood samples are drawn from Day 0 through Day 120 (120 days for whole liver treatment) |
