Acute Myeloid Leukemia—Child(AML—Child; Acute Myelogenous Leukemia—Child; Acute Myeloblastic Leukemia—Child; Acute Granulocytic Leukemia—Child; Acute Nonlymphoblastic Leukemia—Child)

Leukemia is a type of cancer that develops in the bone marrow. With acute myeloid leukemia (AML), the bone marrow makes abnormal myeloid cells that are precursors to blood cells, including:

  • Myeloblasts (a type of white blood cell) that fight infection
  • Red blood cells that carry oxygen
  • Platelets that make blood clots and stop bleeding in cuts and bruises

The leukemia cells do not function normally. They cannot do what normal blood cells do, like fight infections. The abnormal cells also overgrow the bone marrow, forcing normal cells out. Without normal cells, anemia and bleeding problems develop. They also cannot fight infections properly.

Cancer occurs when cells in the body divide without control or order. Normally, cells divide in a regulated manner. If cells keep dividing uncontrollably when new cells are not needed, a mass of tissue forms. The term cancer refers to malignant growth of cells or tissue. These growths can invade nearby tissues. Cancer that has invaded nearby tissues can then spread to the blood and other parts of the body.

It is not clear exactly what causes these problems in the cells, but it is probably a combination of genetics and environment.

Risk Factors

AML is more common in those of Hispanic descent. Other factors that may increase your child's risk of AML include:

  • Genetic factors:
    • Having a sibling, especially an identical twin, who develops leukemia
    • Having a genetic condition, such as Down syndrome
  • Exposure to radiation
  • Exposure to certain chemicals, such as benzene, a chemical used in the cleaning and manufacturing industries
  • History of other blood disorders, such as polycythemia vera, essential thrombocytosis, or myelodysplastic syndrome

AML may cause:

  • Fever
  • Frequent infections
  • Shortness of breath
  • Paleness (a sign of anemia)
  • Easy bruising or bleeding
  • Petechiae (flat, pinpoint spots under the skin caused by bleeding)
  • Weakness, fatigue
  • Loss of appetite, weight loss
  • Bone and joint pain
  • Painless lumps in the neck, underarms, stomach, or groin
  • Bleeding gums

The doctor will ask about your child’s symptoms and medical history. A physical exam will be done. The doctor will check for swelling of the liver, spleen, and lymph nodes.

Test to assess bodily tissues or other structures include:

Imaging tests are used to evaluate bodily structures. These may include:

Once AML is identified, it can be classified. These subtypes are based on the type of cell from which leukemia developed. This is important because it can help the doctor make a prognosis and develop a treatment plan.

Talk with the doctor about the best plan for your child. Treatment of AML usually involves 2 phases:

  • Remission induction therapy—to kill leukemia cells
  • Consolidation—additional chemotherapy to kill any remaining leukemia cells that could grow and cause a relapse
  • Maintenance therapy—not needed for children with AML

Treatment may include:

  • Chemotherapy—usually with multiple medications given into a vein and the spinal column
  • External beam radiation therapy—targets a certain part of the body
  • Stem cell transplant—to replace the affected bone marrow with healthy bone marrow after complete destruction with treatment in children
    • without complete remission
    • with intermediate-risk disease
    • with poor-risk disease or unable to tolerate chemotherapy
  • Other drug therapy may be used to kill leukemia cells, stop them from dividing, or help them mature into white blood cells
  • Biological therapy—involves using medicine or substances made by the body to increase or restore the body’s natural defenses against cancer
  • Antibiotics to treat and prevent infections
  • Medications to treat anemia and treatment side effects, such as like nausea and vomiting

There are no current guidelines to prevent AML because the cause is unknown.
