description Philadelphia chromosome‐positive acute lymphoblastic leukemia has a poor prognosis, even in pediatric patients. Although imatinib‐containing chemotherapy can reportedly improve early event‐free survival, allogeneic hematopoietic stem cell transplantation is still considered to be the main curative treatment option. Dasatinib, a novel abl tyrosine kinase inhibitor, is being used for the treatment of relapsed or refractory Philadelphia chromosome‐positive acute lymphoblastic leukemia and is reported to have excellent efficacy. We used dasatinib after bone marrow transplantation prior to the anticipated relapse for the purpose of prophylaxis against relapse. After discontinuation of dasatinib administration, molecular remission has lasted for 7 months. Although preventive use of dasatinib is as yet uncommon, we consider that dasatinib may eradicate the minimal residual disease and prevent recurrence, and it is feasible to administer and appears to be safe. Further studies are needed to confirm our experience in this case.
