What is the longest survival time after bone marrow transplantation?

The maximum survival time after bone marrow transplantation varies depending on multiple factors, including individual differences, disease type, transplantation method, and postoperative care, making it difficult to generalize. Patients can survive for extended periods after bone marrow transplantation, even for several decades. For example, for patients with acute myeloid leukemia, the five-year average survival rate after bone marrow transplantation can reach 50%-60%; for patients with aplastic anemia who are under 40 years of age and receive a fully matched sibling transplant, the long-term survival rate can be as high as 80%-90%. However, some patients may experience shorter survival periods due to transplant failure, disease recurrence, complications, or other reasons. Therefore, the survival time after bone marrow transplantation should be comprehensively evaluated based on specific circumstances.
