Acute myeloid leukemia

Translocation t 8;21 q22;q22 in Acute Myeloid Leukaemia. Rueda; Maristela Zocca; Gislaine B.

The reciprocal translocation between chromosomes 8 and leuceia with breakpoints in 8q22 and 21q22 was first reported by Rowley, in1 in a subgroup of patients with acute myeloid leukaemia AML.

It soon turned out that most t 8;21 q22;q22 cases were LMA subtype M2; only occasional leukaemias with this abnormality have been classified as subtype M1 or, even more rarely, subtype M4.


¿Qué causa la leucemia mieloide aguda?

The 8;translocation nieloide to be more frequent in the young and is rare beyond the age of 50 years. The translocation results in the generation on the derivative chromosome 8 of a consistent hybrid gene, ETO-AML-1, 5 that encodes a novel message for haematopoietic cell proliferation.

Since high complete remission rates as well as their duration 6 have generally been found in AML subtype M2 patients with t 8;21 q22;q22 treated with conventional chemotherapy regimens, this translocation has been considered as a prognostic indicator of favourable outcomes. Herein, we present for educational purposes, the images obtained from bone marrow cytological and cytogenetics analyses Figures 1 and 2 of leucemiw AML subtype M2 case seen at the Haematology and Haemotherapy Centre of the State University in Campinas.
