After you leave the hospital, you will be seen regularly in the Department of Blood and Marrow Transplantation at MD Anderson. The frequency of the visits may vary, but may be as often as daily. Routine blood (1-2 tablespoons) and urine tests will be performed. The frequency of blood tests may also vary, but may be performed daily. You will have bone marrow samples collected before transplant and then as needed during the first 100 days after transplant, every 3 months during the first year after transplant, and then once a year while you are on study. After that, bone marrow samples will be collected once a year, indefinitely. These samples are being collected to look for tumor (as a staging test) and to looFk for chimerism (the percent of tumor cells detectable that can predict graft failure and/or relapse). To collect a bone marrow sample, an area of the hip or chest bone is numbed with anesthetic and a small amount of bone marrow is withdrawn through a large needle.
