Seventy-one patients with acute myeloid leukemia (AML), most of them (63/71) considered ineligible for conventional allogeneic hematopoietic stem cell transplantation (HSCT), were enrolled into a phase II study on reduced intensity myeloablative conditioning with fractionated 8 Gy total body irradiation (TBI) and fludarabine (120 mg/m2). Patients received mobilized peripheral blood stem cells (n=68) or bone marrow (n=3) from siblings (n=39) or unrelated donors (n=32). Thirty-six patients were transplanted in complete remission (CR) and 35 with untreated or refractory disease (non-CR). Median patient age was 51 years (range, 20-66). Sustained engraftment was attained in all evaluable patients. With a median follow-up of 25.9 months (range, 3.7-61.2) in surviving patients, probabilities of overall survival for patients transplanted in CR and non-CR were 81% and 21% at 2 years, respectively. Relapse-free survival rates were 78% and 16%. The cumulative incidence of non-relapse mortality (NRM) in CR patients was 8% at 2 years and beyond, but amounted to 37% at 2 years in non-CR patients. Outcome data in this poor risk population indicate that allogeneic HSCT from related or unrelated donors with 8 Gy TBI/fludarabine conditioning is feasible with low NRM and preserved antileukemic activity in AML patients in first or later CR.
