Acute myeloid leukemia (AML) is a group of blood and bone marrow cancers. This disorder is characterized by incomplete maturation of blood cells and reduced production of other normal hematopoietic stem cells. AML is the most common cause of leukemia related deaths. The prevalence of AML in western countries is about 1/5000, with about 100,000 patients in Europe and about 60,000 patients in the United States.Â
