Acute myeloid leukemia (AML) patients with fms-related tyrosine kinase 3 (FLT3)-internal tandem duplication (ITD) often have a poor prognosis, even after hematopoietic stem cell transplantation (HSCT). We report a case of AML with FLT3-ITD identified upon initial diagnosis, who received HSCT at complete remission after 3 consecutive chemotherapies. However, the patient relapsed when the same FLT3-ITD clone emerged, and finally died. Retrospective analysis revealed an allelic ratio of FLT3-ITD/wild type of 1.1 and 0.0096 upon initial diagnosis and before HSCT, respectively. The detection of any minimal residual FLT3-ITD clone before HSCT is useful in the treatment of AML with FLT3-ITD.
