These leukemias comprise a spectrum of malignancies that, untreated, range from rapidly fatal to slowly growing. In 2013, the estimated number of new AML cases in the United States was 14,590. The incidence of AML is ~3.5 per 100,000 people per year, and the age-adjusted incidence is higher in men than in women (4.5 vs 3.1). AML incidence increases with age; it is 1.7 in individuals age 65 years. The median age at diagnosis is 67 years.
