General Information About Adult Acute Myeloid Leukemia (AML)

AML is also called acute myelogenous leukemia and acute nonlymphocytic leukemia.

Incidence and Mortality

Estimated new cases and deaths from AML in the United States in 2020:[1]
  • New cases: 19,940.
  • Deaths: 11,180.
Based on Surveillance, Epidemiology, and End Results (SEER) Program 18 data from 2009 to 2015, 28.3% of patients with AML were alive 5 years after diagnosis.[2]

Anatomy

ENLARGEBlood cell development; drawing shows the steps a blood stem cell goes through to become a red blood cell, platelet, or white blood cell. A myeloid stem cell becomes a red blood cell, a platelet, or a myeloblast, which then becomes a granulocyte (the types of granulocytes are eosinophils, basophils, and neutrophils). A lymphoid stem cell becomes a lymphoblast and then becomes a B-lymphocyte, T-lymphocyte, or natural killer cell.
Blood cell development. A blood stem cell goes through several steps to become a red blood cell, platelet, or white blood cell.
AML is a heterogenous group of blood cancers that arise as a result of clonal expansion of myeloid hematopoietic precursors in the bone marrow. Not only are circulating leukemia cells (also called blasts) seen in the peripheral blood, but granulocytopenia, anemia, and thrombocytopenia are also common as proliferating leukemia cells interfere with normal hematopoiesis.[3]
