What is the life expectancy after a bone marrow transplant?
The life expectancy, survival rate and quality of life after a bone marrow transplant have improved considerably with more accurate genetic matching with donors, following up transplantation with an antibiotic regimen to control infections, and improved post-transplant care, in general.
Cancer and other diseases of the blood and bone marrow, which is responsible for manufacturing blood cells, may require a bone marrow transplant from a healthy, genetically compatible donor. Ideally, the donor marrow replaces diseased cells to allow the body to maintain healthy levels of red blood cells, white blood cells, and platelets.
How long can you live after a bone marrow transplant?
Understandably, transplants for patients with nonmalignant diseases have a much better success rate with 70% to 90 % survival with a matched sibling donor and 36% to 65% with unrelated donors.
Transplanting the patient’s own bone marrow from an unaffected bone to a diseased one (autologous bone marrow transplant) along with chemotherapy has improved survival rates with certain cancers such as:
Transplants of younger patients have a higher chance of success.
What is the risk of complications or side effects from bone marrow transplantation?
Prevention of viral infections and management of graft-versus-host disease (or GVHD, in which immune cells in donor tissue attack the transplant patient’s own tissues), and reimmunization through vaccination are important for optimal survival.
Testing positive for small amounts of cancer cells after treatment (minimal residual disease or MRD) in children with acute lymphoblastic leukemia was a risk factor for relapse. The life expectancy increased markedly in those who tested negative for bone marrow MRD before their allogeneic transplant. The MRD-negative patients had a leukemia-free survival rate of 83% and overall survival rate of 92% – much higher when compared with patients with persistent MRD.
Patients with persistent MRD pre-transplant had survival rates of 41% leukemia-free and 64% overall. In patients with MRD measured after the transplant, the survival rate dropped to 35% leukemia-free and 55% overall.
Another study on adult survivors of bone marrow transplant revealed lower patient quality of life when any of the following conditions are present:
Currently, the success of bone marrow transplantation in treatment of many cancers – including some brain tumors – has fallen short of expectations. Researchers continue to improve transplant techniques, however, including improvements in matching donors and recipients, as well as better post-transplant care.
