More than 5,200 children and adolescents (ages 0-19) will be diagnosed with a primary brain tumor in the U.S. this year alone. Whether benign (noncancerous) or malignant (cancerous), brain tumors can have lasting and life-altering physical, cognitive, social, and emotional impacts on a patient’s life.
Pediatric brain tumors can differ from those in adults in terms of the specific types of tumors that are most common. For example, medulloblastomas and ependymomas are more prevalent in children, while glioblastomas are more common in adults.
The most common primary brain tumor types in children and adolescents ages 0-19 years are:
- Pilocytic astrocytoma (15.3%)
- Embryonal tumors (9.2%)
- Medulloblastoma account for the latest percentage of embryonal tumors in this population (69.5%).
There can be differences in the genetic and molecular characteristics of pediatric and adult brain tumors. Certain genetic mutations and markers may be more common in pediatric cases, influencing treatment options and responses. Treatment strategies for pediatric and adult brain tumors can vary due to differences in tumor biology, growth patterns, and the developing brain in children.
