Introduction

Childhood cancer encompasses a diverse group of malignancies that affect infants, children, and adolescents. Understanding the various types of childhood cancers is crucial for early detection, accurate diagnosis, and effective treatment planning. This lecture provides an overview of the most common types of childhood cancers, their epidemiology, clinical features, and treatment considerations.

Types of Childhood Cancers

  1. Leukemias

    • Acute Lymphoblastic Leukemia (ALL): Most common childhood leukemia, originating in the bone marrow.
    • Acute Myeloid Leukemia (AML): Less common than ALL, characterized by abnormal myeloid cell proliferation.
  2. Brain and Central Nervous System (CNS) Tumors

    • Medulloblastoma: A common malignant brain tumor in children, often found in the cerebellum.
    • Gliomas: Includes astrocytomas and ependymomas, arising from glial cells in the brain or spinal cord.
  3. Neuroblastoma

    • A tumor arising from neural crest cells, commonly found in the adrenal glands or nerve tissue along the spine.
  4. Wilms Tumor (Nephroblastoma)

    • A kidney cancer primarily affecting young children, typically diagnosed before age 5.
  5. Lymphomas

    • Hodgkin Lymphoma: Rare in children under 5; characterized by Reed-Sternberg cells.
    • Non-Hodgkin Lymphoma: More common in younger children; arises from lymphoid tissue.
  6. Bone Cancers

    • Osteosarcoma: Most common bone cancer in children and adolescents, often originating in long bones.
    • Ewing Sarcoma: Arises in bones or soft tissues, typically affecting adolescents.
  7. Retinoblastoma

    • A rare eye cancer that develops in the retina of young children, often detected through leukocoria (white pupil).

Epidemiology and Risk Factors

  • Childhood cancers are relatively rare compared to adult cancers, but they remain a leading cause of death in children.
  • Genetic predisposition, environmental factors, and certain genetic syndromes (e.g., Down syndrome) contribute to cancer risk.

Clinical Presentation and Diagnosis

  • Symptoms vary depending on the type and location of the cancer but may include unexplained weight loss, persistent pain, and neurological symptoms.
  • Diagnosis involves imaging studies, blood tests, biopsy, and genetic testing for specific cancers.

Treatment Approaches

  • Surgery: Often the initial treatment to remove tumors and obtain tissue for diagnosis.
  • Chemotherapy: Systemic treatment targeting rapidly dividing cancer cells.
  • Radiation Therapy: Uses high-energy rays to destroy cancer cells.
  • Targeted Therapy: Drugs that specifically target cancer cell mutations or pathways.

End-of-Topic Quiz

  1. Which childhood cancer is characterized by abnormal myeloid cell proliferation?

    • Answer: Acute Myeloid Leukemia (AML)
  2. What is the most common eye cancer in children, typically detected through leukocoria?

    • Answer: Retinoblastoma
  3. Name two types of brain tumors commonly found in children.

    • Answer: Medulloblastoma and gliomas

Summary

Understanding the diverse spectrum of childhood cancers is essential for healthcare professionals involved in pediatric oncology. Early recognition and accurate diagnosis are critical for initiating timely and effective treatment strategies, improving outcomes, and enhancing quality of life for young patients affected by these challenging diseases.
