摘要

Improved outcome of acute myeloid leukemia (AML) depends on the better differentiation of subtypes to predict treatment response and the identification of new target for treatment. In this study, array comparative genomic hybridization (aCGH) was used to distinguish eight cases of AML cases. Validation was performed by FISH and quantitative genomic PCR. The aCGH revealed new large and small recurrent genomic imbalances, such as gains of 1p36, 10q26, 11p15, 20q13, 22q23, harboring many proto-oncogenes. These results better define genetically the studied cases and could be used to understand the multiple phenomena involved in leukemogenesis.
