The diagnosis of AML requires the identification of 20% or more leukemic blasts in the bone marrow. Further analysis then must separate AML from acute lymphoblastic leukemia by showing evidence for commitment to the myeloid lineage.
Prognosis and Predictive Factors. As a group, patients with refractory anemia with excess blasts (RAEB) have a high risk of progression to acute myeloid leukemia (AML), which develops in up to one third of patients. The median survival is 16 months for RAEB-1, whereas it is 9 months for RAEB-2.
