Study Notes
Leukemia in Children
- Leukemia accounts for roughly one-third of all childhood cancers.
- Acute Lymphoblastic Leukemia (ALL) is the most common type of leukemia in children, with peak incidence between the ages of 2 and 5.
- Hispanic and White children have a higher incidence of ALL, and boys are more likely to be diagnosed than girls.
- Acute Myeloid Leukemia (AML) affects children of all races and sexes at a more consistent rate.
- Juvenile Myelomonocytic Leukemia (JMML) is a rare type of leukemia affecting primarily young children.
Symptoms of Leukemia
- Low red blood cell count (RBCs): Can cause weakness, fatigue, dizziness, headache, and pallor.
- Low white blood cell count (WBCs) and platelets: Could result in infection, fever, easy bruising, and bleeding.
- Other symptoms: May include bone and joint pain, weight loss, loss of appetite, swollen lymph nodes, and swelling of the face or arms.
Treatment of Leukemia
- Age at diagnosis and initial WBC count: Are crucial prognostic factors for children diagnosed with acute lymphoblastic leukemia (ALL).
-
Chemotherapy: The primary treatment for children with ALL.
-
ALL treatment phases: Divided into three phases over two to three years.
- Induction phase: Aims to achieve remission.
- Consolidation phase: Targets remaining leukemia cells.
- Maintenance phase: Begins if remission is sustained.
-
ALL treatment phases: Divided into three phases over two to three years.
-
Acute myelogenous leukemia (AML) treatment: Involves higher chemotherapy doses in two phases over a shorter period.
- Induction phase
- Consolidation phase
- High-risk leukemias like juvenile myelomonocytic leukemia (JMML): Might require stem cell transplantation (SCT).
- Other therapies: Include targeted therapy and radiation in specific cases.
Prognosis of Leukemia
- ALL prognosis: Children aged 1 to 9 years with B-cell ALL have the best prognosis.
- AML prognosis: Children generally experience better outcomes compared to adults.
Acute Lymphoblastic Leukemia (ALL) Symptoms
- Low red blood cell count (RBCs) can lead to weakness, fatigue, dizziness, headache, and paleness.
- Low white blood cell count (WBCs) and platelet count can increase susceptibility to infections, fever, easy bruising, and bleeding.
- Other possible symptoms include bone and joint pain, weight loss, loss of appetite (anorexia), swollen lymph nodes, and swelling of the face or arms.
ALL Treatment
- Age at diagnosis and initial WBC count are the strongest indicators of prognosis for children with ALL.
- Chemotherapy is the primary treatment for children with ALL.
- ALL treatment is divided into three phases over 2-3 years:
- Induction: The goal of this phase is to achieve remission, meaning the leukemia is no longer detectable.
- Consolidation: This phase aims to reduce any remaining leukemia cells.
- Maintenance: This phase begins if remission persists and helps to prevent relapse.
Acute Myeloid Leukemia (AML) Treatment
- AML is treated with higher doses of chemotherapy in two phases over a shorter period of time:
- Induction: As in ALL, this phase aims to achieve remission.
- Consolidation: This phase seeks to further reduce any remaining leukemia cells.
High-Risk Leukemias and Other Treatments
- High-risk leukemias, such as juvenile myelomonocytic leukemia (JMML), may require stem cell transplantation (SCT).
- Targeted therapy and radiation may be used in specific cases.
Prognostic Factors
- Children aged 1-9 years with B-cell ALL have the best prognosis for ALL.
- Children with AML generally have better outcomes compared to adults.
Childhood Leukemia
- Leukemia accounts for approximately 30% of childhood cancers.
- Acute Lymphoblastic Leukemia (ALL) exhibits a peak incidence between 6 and 9 years of age.
- ALL is more prevalent among Hispanic and White children.
- AML is more evenly distributed among African American and Asian children.
Types of Leukemia
- Acute Lymphoblastic Leukemia (ALL): Characterized by an accumulation of immature lymphocytes in the bone marrow.
- Acute Myeloid Leukemia (AML): Characterized by an accumulation of immature myeloid cells in the bone marrow.
Symptoms of Leukemia
- Weight loss can be a symptom of low red blood cell count (RBCs) associated with leukemia.
Acute Lymphoblastic Leukemia (ALL) Treatment
- The primary treatment for children with ALL is chemotherapy.
- ALL treatment involves three phases: Induction, Consolidation, and Maintenance.
- Induction aims to achieve complete remission.
- Consolidation aims to eliminate any remaining leukemia cells.
- Maintenance ensures long-term remission.
- Children aged 2-9 years with B-cell ALL have the best prognosis.
Prognosis for Acute Lymphoblastic Leukemia (ALL)
- The two key prognostic factors for ALL are the type of ALL and the child's age.
- Children between 2 and 9 years of age are more likely to have a positive outcome.
Acute Myeloid Leukemia (AML) Treatment
- Treatment for AML typically involves chemotherapy and sometimes bone marrow transplantation.
Prognosis for Acute Myeloid Leukemia (AML)
- Outcomes for children with AML are generally better than those with ALL.
- Children with AML typically have a better prognosis than those with ALL.
Summary of Leukemia Types
- ALL is more common in Hispanic and White children.
- AML is more evenly distributed across racial groups.
- Both types of leukemia are treated primarily with chemotherapy.
- ALL has three phases of treatment (Induction, Consolidation, and Maintenance).
- AML treatment may involve bone marrow transplantation.
- Children with B-cell ALL have the best prognosis, especially those aged 2-9 years.
- Children with AML generally have better outcomes than those with ALL.
