 Patients may enroll on this study at various points in their treatment including diagnosis, recurrence, or just prior to initiation of study mandated transplant therapy. Because patients may enter this study prior to completion of retransplant treatments, the below criteria must be met only to proceed to the high dose chemotherapy and autologous stem cell transplant part of this study. These criteria are not a requirement to enter this study in order to collect tumor or peripheral blood stem cells.
