 At the end of your scheduled treatments, you will be asked to return to the clinic for follow-up visits every 6 months for the first, second, third, and fourth year after treatment on this study. You will then be followed every year after that. If your doctor feels it is necessary, you may have blood tests about 3-5 teaspoons performed at these visits. You will have bone marrow biopsies every other year for the first 2 years, if they were positive before you started on this study, and then every year after that. At these visits, you will be asked about any side effects you may have experienced and whether or not your cancer has come back. If your doctor feels there is a chance that the cancer has come back, he or she may schedule x-rays or scans in order to check. You will also be asked about any other therapies you may be having to treat your cancer, if it has come back.
