ABSTRACT

We present the case of successful treatment of post-transplantation relapse of prognostically unfavorable AML with inv(3)(q21q26), –7 and EVI1 oncogene overexpression, when stable donor hematopoiesis reconstitution was achieved due to one high-dose cytarabine course, DLI, and hypomethylating agents (decitabine, 5-azacitidine). Possible molecular mechanisms of this effect are discussed with respect to the new approaches to management of such patients.

Keywords: acute myeloid leukemia, inv(3)(q21q26), EVI1 high expression, hematopoietic stem cell transplantation, relapse, treatment, donor lymphocyte infusions, hypomethylating agents.
