Lymphocyte Infusion for Delayed Extramedullary Relapse of Acute Leukemia Following Bone Marrow Transplantation

Abstract
We report a case of extramedullary relapse of acute myelogenous leukemia twelve years after allogeneic bone marrow transplantation. Due to the localized nature of the relapse, we were able to eliminate a majority of the tumor burden, utilizing local irradiation. Destined with eventual systemic leukemia relapse, further therapy utilizing donor lymphocytes was given at a time of minimal disease burden. The patient remains in a state of complete remission.
