Background
- AKA Acute myelogenous leukemia or non-lymphocytic leukemia
- Most common acute leukemia in adults (around 80% of cases)
- 65 yo median age of diagnosis, Male:Female 5:3
- Characterized by clonal proliferation of myeloid precursors(blast cells >20% in the periphery)
Clinical Features
- Presents with symptoms of:
- Anemia: weakness, easy fatigability, SOB
- Neutropenia: infections
- Thrombocytopenia: gingival bleeding/enlargement, ecchymoses, epistaxis, menorrhagia
Differential Diagnosis
Acute Leukemia/Lymphoma
Evaluation
- CXR
- CBC with peripheral smear
- Chem7, ca, mg, phos, Uric Acid, UA, LDH (to check for tumor lysis syndrome)
- LFTs, Coags, FDP, D-Dimer, Haptoglobin, Fibrinogen (to check for DIC)
- ESR, CRP
- Reticulocyte count in anemia
- Get extra purple top for flow cytometry, especially before transfusion
Management
- Aggressive IV hydration
- If febrile, complete cultures and broad spectrum antibiotics
- Manage Complications
- See DIC
- See Leukostasis
- See Hyperviscosity syndrome
- See Tumor Lysis Syndrome
- See Retinoic acid syndrome
