Summary
Brief summary (as posted)
A retrospective study using a new technology will be performed: the Optical Genome Mapping (OGM) on acute myelogenous leukemia (AML) samples stored at the CRB-Cancer of the Bordeaux University Hospital and annotated in the DATAML clinical database. The main objective is to estimate the proportion of AML patients for whom OGM detects at least one additional abnormality compared to conventional techniques. This study will constitute an important step in the validation of COA as a reference technique for cytogenetic analysis in AML, replacing the classical techniques, and could also constitute a first argument for redesigning the prognostic classification of AML.
