What is Leukemia?
• Greek: “White Blood” • Cancer of bone marrow (blood-producing) cells
• Immature primitive BM cells, proliferative - acute • Abnormal Complete Blood Count • Short-term survival without therapy • Prognosis varies greatly
• Requires detailed pathology review & diagnosis

AML (2019) Cases: 21,450 Deaths:10,920
Siegel, CA: A Cancer Journal for Clinicians 69:7-34, 2019

Epidemiology of Leukemia Relevance in the Clinic
• The causes of cancer are largely unknown in individual
patients
• Deeply relevant to patients and their families • “Why did this happen to me?” 1 • Impact of the cause on the disease course • Risk of recurrence
• Interventions, appropriate lifestyle changes, etc.
• Recognition of Familial Risk • Impact of specific leukemia risk factors on genetics,
prognosis and outcome after diagnosis largely unstudied

AML Epidemiology Exposures Identified in Case-Control Studies

Some risk factors that have been associated with AML development identified in PopulationBased Case-Control Studies • Not proof of
causality, but suggests increased risk • Further studies ongoing

Acute Leukemia

• Complications of Leukemia:

• Infection

Rapid onset, esp. if neutropenia

• Bleeding

Low platelets, low fibrinogen DIC

• Clotting

Hypercoagulable, even if low platelets

• Fatigue

Anemia, transfusions

• Leukostasis “Sludging” - confusion, stroke, bleed,

cardiopulmonary symptoms

• Importance of coordinated clinic evaluation & hospital care • Acute Leukemia Must see in 24-48 hours whenever possible • Frequently direct hospital transfer , or being admitted for
urgent evaluation and initiation of treatment
• ~4 week intensive “remission induction” therapy
