Acute Myeloid Leukemia With a Rare t(7;14)(q21;q32) and Trisomy 4 With Poor Clinical Outcome: A Case Report

Research output: Contribution to journalArticle

Abstract

Objectives: Recurrent cytogenetic abnormalities and/or molecular aberrations play an important role in the diagnosis and prognostification of acute myeloid leukemia (AML). We describe a case of a 40 year old woman diagnosed with de novo AML with a novel t(7;14)(q21,q32) and trisomy 4 with poor clinical outcome. Methods: Morphologic, flow cytometry and cytogenetic results of the patient's peripheral blood and bone marrow samples were analyzed.

Results: The diagnostic bone marrow was hypercellular for age (>95%) with increased blasts (62%) that by flow cytometry exhibited myeloid differentiation with a few T/NK lineage markers. Cytogenetics showed a t(7;14)(q21,q32) and trisomy 4. The patient had extremely poor response to two rounds of induction chemotherapy with persistent leukemia following therapy.

Conclusion: To the best of our knowledge, the t(7;14) is a novel cytogenetic abnormality that has not been reported previously in acute myeloid leukemia, and is important to report as it appears to be associated with poor prognosis.
