Objectives

  • Define acute leukemia and how it is differentiated from chronic leukemia.
  • Describe the various causes and risk factors of leukemia, as well as the pathophysiology of the disorder.
  • Describe the major World Health Organization classifications of acute myeloid leukemia and the criteria that differentiate them.
  • Describe the major World Health Organization classifications of acute lymphoblastic leukemia and the criteria that differentiate them.
  • Identify the criteria by which we classify acute leukemias and how the current World Health Organization classifications differ from the previous French-American-British classifications.
  • Differentiate between acute lymphoblastic leukemia and acute myeloid leukemia regarding causes, patient populations, symptoms, and prognostic factors.
  • Differentiate and describe the criteria and diagnostic techniques among the major acute lymphoblastic leukemia and acute myeloid leukemia groups.
