Acute myeloid leukemia can be classified into seven major categories. In the 2016 revised WHO classification of AML, there are seven categories: (1) AML with reproducible genetic abnormalities; (2) AML with gene mutations; (3) AML with myelodysplasia-associated lesions; (4) treatment-associated myeloid neoplasms; (5) acute myeloid leukemia, non-specific; (6) myelosarcoma; and (7) myeloproliferative-associated Down’s syndrome. Of the AMLs, acute promyelocytic leukemia, has a relatively best prognosis. The prognosis of the other AMLs is stratified primarily according to genetic characteristics, including low, intermediate, and high risk. Patients with acute myeloid leukemia should wait patiently for the results of the doctor’s examination to assist in the clinical diagnosis and receive treatment under the guidance of the physician.
