Relapse remains the most common cause of treatment failure after hematopoietic cell transplantation for acute myeloid leukemia. Inability to achieve hematologic complete remission has been a barrier to transplant for patients with refractory disease. We describe six children with refractory myeloid disease undergoing transplant in chemotherapy-induced aplasia, as a strategy to facilitate curative therapy in refractory patients. Clofarabine- or high-dose cytarabine-based chemotherapy regimens were used to achieve marrow aplasia, followed by reduced-intensity conditioning and allogeneic transplant before hematologic recovery. Long-term disease control was achieved in five, with one transplant-related mortality, suggesting the feasibility of this approach.
