HaematologyTier 1Topic overview

Haematological malignancies - leukaemia, acute and chronic

Framing

  • Leukaemia is classified along two axes - acute vs chronic (blast-predominant, rapidly progressive disease vs a more indolent clonal proliferation) and lymphoid vs myeloid (cell lineage of origin) - producing four principal categories, each with a distinct age distribution, presentation, and treatment approach
  • This classification directly predicts urgency: acute leukaemias require prompt treatment given rapid marrow failure, while chronic leukaemias are often managed expectantly or with risk-stratified, non-curative-intent therapy
