NEOPLASIA Complete molecular response of e6a2 BCR-ABL–positive acute myeloid leukemia to imatinib then dasatinib1 Department of Haematology and Medical Oncology, Peter MacCallum Cancer Centre, Melbourne; 2 Department of Pathology, University of Melbourne, Parkville; and 3 Department of Pathology, Peter MacCallum Cancer Centre, Melbourne, Australia De novo presentation of acute myeloid leukemia (AML) expressing the Philadelphia (Ph) chromosomal abnormality is rare and is associated with a dismal prognosis. To date, reported cases of Ph+ AML have expressed either the e13a2 or e14a2 BCR-ABL fusion transcripts. We report a unique case of de novo AML expressing the e6a2 fusion transcript and describe disease sensitivity to both imatinib before allogeneic stem-cell transplantation and dasatinib for AML relapse after allogeneic stem-cell transplantation. Furthermore, we report that sustained molecular remission has been achieved despite withdrawal of tyrosine kinase inhibitor (TKI) therapy.
