    Study Notes

    Childhood Leukemia

    • Leukemia accounts for almost one-third of cancers diagnosed in children.
    • Acute lymphoblastic leukemia (ALL) is the most common type.
    • Acute myelogenous leukemia (AML) is the second most common type.
    • ALL is more common among Hispanic and white children than African American and Asian children.
    • ALL is more common in boys than girls.
    • AML is present in equal amounts between boys and girls across all races.
    • Juvenile myelomonocytic leukemia (JMML) is a rare form of leukemia occurring most often in children under age 4.
    • There are currently no screening procedures or blood tests to identify leukemia before symptoms.
    • Common symptoms include: weakness, fatigue, dizziness, headache, pallor (decreased RBCs), infection, fever, easy bruising, bleeding (decreased WBCs and platelets), bone or joint pain, weight loss, anorexia, swollen lymph nodes, and swelling of the face and arms.
    • Age at diagnosis and initial WBC count are the most important prognostic factors.
    • Children aged 1 to 9 years with B-cell ALL have better cure rates.
    • Children diagnosed with AML younger than 2 years have a better prognosis.
    • The main treatment for childhood leukemia is chemotherapy.
    • ALL is treated in three phases: induction, consolidation, and maintenance.
    • AML is treated in two phases: induction and consolidation.
    • Children with leukemia must be treated in experienced facilities due to risks from intensive treatment.
    • Stem cell transplantation (SCT) may be used for higher-risk leukemias like JMML.
    • The 5-year survival rates for children with ALL and AML are approximately 91% and 66%, respectively.
    • Research is ongoing in understanding the link between DNA changes in stem cells and leukemia development and how it impacts treatment.
    • Immunotherapy treatments like chimeric antigen receptor (CAR) T-cell therapy and monoclonal antibody therapy show promise in treating ALL.

    Challenges for Childhood Leukemia Survivors

    • Treatment for childhood leukemia can lead to long-term effects, including chronic conditions and premature death, such as chronic fatigue, heart problems, growth hormone deficiency, infertility, osteoporosis, secondary cancers, obesity, and hypertension.
    • Survivors have a higher incidence of chronic fatigue starting as early as 16 years after treatment completion.
    • It is important for nurses to promote healthy habits and lifestyle choices to help survivors minimize future health challenges.

    Leukemia in Pregnant Women

    • AML is one of the most common hematologic cancers diagnosed in pregnant women.
    • Treatment during pregnancy is challenging due to the teratogenic effects of chemotherapy and targeted therapies on the fetus, especially in the first trimester.
    • Delaying treatment may be risky for the mother, and termination of pregnancy may be necessary to save her life.

    Leukemia in Older Adults

    • Chronic lymphocytic leukemia (CLL) is considered a disease of older adults, with a median age of onset of 70 years.
    • Most patients are diagnosed in the early stages and can remain asymptomatic for years.
    • A Comprehensive Geriatric Assessment (CGA) is recommended for patients 65 years or older to assist in treatment selection.
    • Treatment is given only to patients with symptoms of active disease.
    • Ibrutinib has become the preferred first-line treatment.
    • Combination therapies using chemotherapeutic agents and targeted therapies have shown greater progression-free survival rates.
    • Clinical trials are investigating other combination therapy regimens.

    AML in Older Adults

    • AML is the second most common type of leukemia in adults, with a median age at diagnosis of 67 years.
    • Older adults have a 5-year survival rate of 5% due to limitations in treatment options.
    • Treatment is highly individualized.
    • Older adults may respond poorly to induction chemotherapy.
    • Venetoclax in combination with lower-dose chemotherapy is a safer and more effective approach for older adults with AML.
