Before you can start treatment on this study, you will have what are called "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. Your 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, and pelvis. You will have a bone marrow aspirate and biopsy performed. To collect a bone marrow aspirate and biopsy, an area of the hip or chest bone is numbed with anesthetic, and a small amount of bone marrow and bone is withdrawn through a large needle. Women who are able to have children must have a negative blood pregnancy test.
