After a bone marrow transplant for leukemia, the condition can generally be called cured if it reaches complete remission and does not relapse for ten years. 1. Clinically, in the process of treating leukemia, the effect of leukemia treatment can be judged by three criteria: complete remission, partial remission and no remission. (1) Complete remission: clinical manifestations of no symptoms and signs caused by leukemia infiltration, and normal or near-normal life. (2) Partial remission: one of the two clinical blood tests does not meet the criteria for complete remission. (3) Not in remission: Bone marrow picture, blood picture and clinical symptoms do not meet the above criteria. 2. If the leukemia is in remission after bone marrow transplantation, the survival period reaches five years from the date of leukemia diagnosis, which can be called long-term survival. If the disease reaches complete remission and does not relapse for ten years, it can be called a cure. Generally, the cure rate of leukemia after bone marrow transplantation is high, but the type of the patient’s disease, the function of the body organs, autoimmune reaction, complications during the transplantation process and the rate of matching the genetic loci of the donor and the patient, and the overall level of the transplantation hospital will affect the success rate of the bone marrow transplantation. After leukemia bone marrow transplantation, the general condition is in complete remission and no relapse for ten years, which can be called a cure, but there are still special cases, and in general, the recovery after the operation is good. It is recommended to go to the hospital regularly for rechecking, keep optimistic mood, intake of adequate nutrition, and make good postoperative recovery. Specific treatment under the guidance of physicians.
