The cost of a leukemia transplant can range from as little as $200,000 to $400,000 to as much as $1 million or more. The cost of a leukemia transplant is related to whether the patient has a serious infection during the transplant process, whether he or she has severe graft-versus-host disease, and the frequency of blood transfusions. 1. If there is a serious infection secondary to the transplant, the cost of treatment for the patient will be much higher. 2. If there is severe graft-versus-host disease during transplantation, the cost to the patient will also be abnormally high. 3. If the blood cells rebound quickly during transplantation, the cost of blood transfusion will be low, while if the blood cells continue not to rebound during transplantation, and repeated transfusion of red blood cells, platelets and other blood products is required, the cost will be higher. The exact cost varies from person to person, and it is recommended that patients receive treatment under the guidance of a physician.
