Bone marrow transplantation in leukemia.

Bone marrow transplants are increasingly being used as treatment for leukemia. Several IBMTR studies have identified variables predicting outcome in allogeneic transplants. These studies have also identified factors like GVL that increase our understanding of leukemia treatment. Following the success of HLA-identical sibling transplants, allografts from related and unrelated donors are now performed frequently and achieve long-term LFS. The use of autologous transplants, with and without marrow treatment, is also increasing and continues to be investigated as an alternative therapy for leukemia.
