The cost of bone marrow transplantation treatment for acute lymphoblastic leukemia is about $200,000 without any complications. Induction chemotherapy and intensive consolidation chemotherapy before bone marrow transplantation will require about $100,000 in treatment costs, plus bone marrow transplantation will require about $100,000 in treatment costs. Therefore, the total cost required for bone marrow transplantation treatment for acute lymphoblastic leukemia is about $200,000 or so. However, complications such as bacterial and viral infections and severe hematopoiesis may occur during chemotherapy and bone marrow transplantation, requiring supportive treatments such as anti-infections, blood and platelet transfusions, etc. The treatment costs required are related to the severity of the disease and are difficult to predict. Acute lymphoblastic leukemia is a malignant blood disease, and bone marrow transplantation is the only treatment that has the hope of curing the disease completely. Before bone marrow transplantation, it is necessary to carry out induction chemotherapy and intensive consolidation chemotherapy, so as to minimize the primitive and naïve lymphocytes in the bone marrow as much as possible, in order to increase the success rate of bone marrow transplantation. Patients with acute lymphoblastic leukemia are advised to visit the Department of Hematology for a comprehensive assessment of the patient’s condition and an estimate of the treatment cost.
