For leukemia, due to irresponsible propaganda or even deliberate misinformation by individual media, many patients and even some lay medical professionals have the misconception that a bone marrow transplant is necessary to treat leukemia! In fact, this perception is very wrong! The cure rate of drug therapy: In recent years, drug therapy for leukemia has been gaining ground, and the cure rate of childhood acute lymphoblastic leukemia has reached 80%, and the cure rate of acute promyelocytic leukemia has long exceeded 90%, and leukemia can be cured by drug therapy has long become a reality. Risks of bone marrow transplantation: Bone marrow transplantation must face many difficulties such as hepatic vein obstruction disease, graft-versus-host disease, diffuse alveolar hemorrhage, implantation failure, severe infection, etc. Even if the transplantation is successful, it must face long-term complications such as secondary tumors. The cost of bone marrow transplantation: Patients must first achieve complete remission, which costs about 100,000 to 300,000 RMB, and the cost of bone marrow transplantation from “in” to “out” is 300,000 to 400,000 RMB. Secondly, the mental, emotional and physical costs of bone marrow transplantation are much higher for patients and families than for patients treated with drugs. Indications and contraindications for transplantation: Currently, bone marrow transplantation is only used as a treatment for some high-risk, relapsed and refractory cases, and bone marrow transplantation is contraindicated for patients over 60 years of age, patients with cardiac, hepatic and renal insufficiency, and patients with severe infections.
