Acute lymphoblastic leukemia is a type of acute leukemia, and acute lymphoblastic leukemia is more common in pediatric patients. It generally takes about two and a half years to treat acute lymphoblastic leukemia and costs about 300,000-500,000 yuan because acute lymphoblastic leukemia, due to the disorderly proliferation of leukemia cells in the bone marrow, leads to the destruction of normal hematopoietic function, and patients develop a series of symptoms such as anemia, infection and organ infiltration. Chemotherapy drugs commonly used to treat acute lymphoblastic leukemia include cyclophosphamide, vincristine, adriamycin, glucocorticoids, methotrexate, 6-mercaptopurine, etc. These chemotherapy drugs are not particularly expensive, but the treatment period is relatively long, and after treatment patients will have a series of complications such as infection and bleeding, requiring blood transfusion and anti-infection symptomatic treatment, costing about 300,000 yuan. If allogeneic hematopoietic stem cell transplantation is needed, the cost will be more. The cost of transplantation will vary depending on whether the donor is fully compatible or semi-compatible, and whether the patient has complications during the transplantation process.
