autologous bone marrow transplantation

autologous bone marrow transplantation

A procedure in which haematopoietic stem cells are extracted (apheresed) from a patient with lymphoma and other cancers, who is treated with high-dose chemo- and/or radiotherapy to eliminate malignant cells in the bone marrow. The stem cells are then administered. ABMT is a standard second-line therapy for some lymphomas; it has a low risk of infection and has no risk of graft-versus-host disease, which is typical of allogeneic bone marrow transplantation. ABMT is less preferred for patients with acute myeloid leukaemia, in whom the relapse may occur as the patient’s marrow may contain malignant cells.
