Long-term remission of therapy-related acute myeloid leukemia with a new t(11;18)(q23;q21.2) translocation and KMT2A-ME2 (MLL-ME2) fusion gene
2015
Abstract
We describe a unique case of a woman with acute myeloid leukemia with a new, previously undescribed translocation, t(11;18)(q23;q21.2), affecting the KMT2A (MLL) gene and resulting in an KMT2A(MLL)-ME2 fusion. This disease occurred secondarily following chemotherapy for a different acute myeloid leukemia with the recurrent genetic abnormality inv(16)(p13.1;q22).
The secondary leukemia was treated with intensive chemotherapy without allogeneic hematopoietic cell transplantation. Complete remission lasting more than 10 years has been achieved with concurrent and sustained remission of the primary leukemia.
