Pathology
AML is a malignant proliferation of haematopoietic precursor blast cells of non-lymphoid lineage
Aetiology
AML usually develops without a clear precipitant.
Commonest leukaemia in adults
Signs
Gum hypertrophy, fleshy nodules, hypoxia, retinal haemorrhage, confusion,
Lymphadenopathy, hepatomegaly, splenomegaly, lymphadenopathy, bone pain
Symptoms
Anaemia, infection, bruising and bleeding
Investigations
Bloods: FBC shows pancytopaenia with circulating blast cells
Blood Film – Auer Rods
Bone marrow aspirate – Hypercellular and increased number of blast cells
Cytogenetics: Screen for molecular mutations
Treatment
Medical: Treat infections early, blood transfusion, chemotherapy,
immunotherapy, stem cell transplantation
Prognosis
Variable depending on: age (<50 favourable), cytogenetic abnormalities, molecular genetic abnormalities, presenting blast count (<25 unfavourable), AML classification, preceding myelodysplasia (poor prognosis).
Infection, bleeding, organ damage, hair loss, GI toxicity, Infertility
