Answer

Several molecular abnormalities that are not detected with routine cytogenetics have been shown to have prognostic importance in patients with AML. The bone marrow should be evaluated at least with the commercially available tests. Patients with APL should have their marrow evaluated for the PML/RARa genetic rearrangement. When possible, the bone marrow should be evaluated for Fms-like tyrosine kinase 3 (FLT3) and nucleophosmin (NPM1) mutations.
