The current 5-year survival rate of bone marrow transplantation is around 50%~60%, but it varies according to different diseases, such as acute leukemia and aplastic anemia. 1. If a patient develops acute leukemia, the 5-year survival rate after bone marrow transplantation can be about 50%~60%. 2. If the patient develops aplastic anemia, for people younger than 40 years old, and if a suitable HLA sibling donor is found, the 5-year survival rate after bone marrow transplantation can be as high as 80%. However, there are still some aplastic anemia patients who have relapsed within 3 years after receiving a bone marrow transplant, and the subsequent treatment of such patients is less effective. It is recommended that patients in need of bone marrow transplantation should go to the hospital as early as possible for matching, wait for a suitable bone marrow source, and prepare for bone marrow transplantation in advance. The specific transplantation process and the use of drugs need to be carried out under the guidance of a physician.
