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 the study. You will have a complete medical history and physical exam Blood (about 2 tablespoons) will be collected for routine tests. A bone marrow sample will be collected to learn if your Hodgkin's lymphoma has spread to the bone marrow. To collect a bone marrow sample (biopsy), an area of the hip bone is numbed with anesthetic and a small amount of bone marrow is withdrawn through a large needle. A CT scan or MRI of the chest, abdomen (stomach), and pelvis (waist area) will be done. You will also have a PET scan or a Gallium scan to check on the status of the disease. You will be required to have a heart scan or an echocardiogram to check how strong your heart muscle is. You will be asked about medications that you are currently taking, including over-the-counter medications. Women who are able to have children must have a negative blood pregnancy test.
