You will need to stay in the hospital about 3 to 4 weeks. You will be taken off study if their disease gets worse or intolerable side effects occur. You must stay in the Houston area for about 100 days after the transplant. After that, you will be asked to return to Houston every 6 months for the next 3-5 years for scans (CT, gallium, or PET scans), and bone marrow aspirations over the next 3-5 years.
