Brief summary
Hyper-leukocytosis \> 50.109/L is observed in 15% of acute myeloid leukemia (AML). Level of hyper-leukocytosis is linearly associated with the incidence of life threatening complications that lead to the early death in 25% of these patients. The HEAL project is a prospective, uni-centric, observational study that plans to include a cohort of 50 patients presenting de novo AML with hyper-leukocytosis (HL) (\> 50.109/L) and 10 controls. The aim of the study is to describe the relative proportion of various hemostasis components disturbances, endothelium alterations, platelet dysfunction and to calculate cumulative incidence of hemorrhagic and thrombotic complications as well as overall survival of patients presenting with HL AML.
