Cytogenetic analysis is still important in the management of many hematological malignancies, despite the new techniques available such as the high-throughput sequencing analysis, and the discovery of many acquired gene mutations in these diseases. The Groupe francophone de cytogénétique hématologique (GFCH) published in 2004 the recommendations for the cytogenetic management of hematological malignancies. It reports here the update of these recommendations, with a review of the literature for each disease.
