Every 2 cycles about every 8 weeks, you will have bone marrow biopsies performed if they were positive before starting on this study, until they come back negative. You will have a positron emission tomography PET scan to see if the tumor is responding. Once the PET scan comes back negative, it will be up to your physician to decide if you need additional PET scan tests, and when. You will have CT scans of the chest, abdomen, pelvis, and neck every 2 cycles, if they were positive at the beginning of the study also.
