Abstract

Background Acute myeloid leukemia (AML) with specific balanced 5q33 translocations are classified as AML with myelodysplasia-related changes regardless of their morphologic findings or antecedent hematologic disease, but the clinicopathologic features of such cases remain poorly understood. Materials and Methods From > 2000 cases of hematological malignancies seen at our institution between 2000 and 2013, we identified 9 AML patients with 5q33 translocations with variable partner loci, t(v;5q33). Results The study group included 8 men and 1 woman, with a median age of 64 years (range, 19-87 years). Four patients had an antecedent myeloproliferative neoplasm (MPN). Cytogenetic analysis showed t(v;5q33) as a sole chromosomal abnormality in 4 (44%) patients, t(v;5q33) and del(3)(q21;q26.2) in 1 (11%) patient, and a complex karyotype in 4 (44%) patients. Only 1 patient had morphologic features of myelodysplasia in 2 or more lineages. Follow-up was available for 7 patients and the median overall survival (OS) was 12 months. Patients with a history of MPN had a significantly shorter OS compared with those with de novo AML (11 vs. 20 months; P = .0445). There was no correlation between complex karyotype and OS in this small group of AML patients (P = .5904). Conclusion The t(v;5q33) is a rare cytogenetic aberration in AML. Although associated with a poor outcome, AML with t(v;5q33) usually lacks morphologic evidence of multilineage dysplasia. Patients who have AML with t(v;5q33) after MPN have a worse OS compared with those with de novo AML.
