Before you can start treatment on this study, you will have "screening tests." These tests will help the doctor decide if you are eligible to take part in this study. You will have a physical exam. Blood (about 2 to 3 teaspoons) and urine will be collected for routine tests. You will have a chest x-ray and computerized tomography (CT) scans of the neck, chest, abdomen (stomach area), and pelvis.
