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.
  • Differentiate between acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) regarding causes, patient populations, symptoms, and prognostic factors.
  • Identify criteria by which we classify acute leukemias and how the current WHO classifications differ from the previous FAB classifications
  • Describe the major WHO classes of acute myeloid leukemia (AML) as well as criteria that differentiate them.
  • Differentiate and describe the diagnostic techniques and criteria among the major acute myeloid leukemia (AML) groups.
  • Differentiate and describe the criteria and diagnostic techniques among the major acute lymphoblastic leukemia (ALL) groups.
  • Describe the major WHO classifications of acute lymphoblastic leukemia (ALL), patient populations, and prognostic factors.
