Initial Diagnostic Workup for Acute Myeloid Leukemia (AML) in Adult Patients

NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) initial evaluation includes:

CBC, complete blood count; CT, computed tomography; FISH, fluorescent in situ hybridization; HCT, hematopoietic stem cell transplant; HLA, human leukocyte antigen; LP, lumbar puncture; MRI, magnetic resonance imaging; MUGA, multigated acquisition; PET, positron emission tomography; PT, prothrombin time; PTT, partial thromoplastin time.
aThe WHO 2016 classification defines acute leukemia as ≥20% blasts in the marrow or blood. In an appropriate clinical setting, a diagnosis of AML may be made with less than 20% in patients with the following cytogenetic abnormalities: t(15;17), t(8;21), t(16;16), inv(16). AML evolving from MDS (AML-MDS) is often more resistant to cytotoxic chemotherapy than AML that arises without antecedent hematologic disorder and may have a more indolent course. Some clinical trials designed for high-grade MDS may allow enrollment of patients with AML-MDS.
