During treatment, you will have a physical exam, including measurement of your vital signs. You will have blood drawn (about 1 tablespoon each) at least once a week and sometimes up to 3 times a week. After 1 or 2 courses of chemotherapy, the tests done during the screening visit will be repeated to check for disease response to treatment. A bone marrow biopsy will be repeated starting at 2 weeks into therapy. This biopsy will be repeated about every week until the disease response to treatment is known.
