Overview
Epidemiology and Demographics
Incidence
Acute myeloid leukemia is a relatively rare cancer. There are approximately 10,500 new cases each year in the United States, and the incidence rate has remained stable from 1995 through 2005. AML accounts for 1.2% of all cancer deaths in the United States.
Age
The incidence of AML increases with age; the median age at diagnosis is 63 years. AML accounts for about 90% of all acute leukemias in adults, but is rare in children. The rate of therapy-related AML (that is, AML caused by previous chemotherapy) is rising; therapy-related disease currently accounts for about 10–20% of all cases of AML.[1]
Gender
AML is slightly more common in men, with a male-to-female ratio of 1.3:1.[2]
Developed Countries
- There is some geographic variation in the incidence of AML. In adults, the highest rates are seen in North America, Europe, and Oceania.
- In contrast, childhood AML is less common in North America.
Developing Countries
- Adult AML is rarer in Asia and Latin America.[3][4]
- Childhood AML is less common in India than in other parts of Asia.[5]
These differences may be due to population genetics, environmental factors, or a combination of the two.
