Percentage of adults and children diagnosed with medulloblastoma
Children comprise 70% of all medulloblastoma cases
  • Approximately 435 patients are diagnosed each year in the US, with more than 70% of them being pediatric.
  • There are an estimated 6,000 people living with medulloblastoma.
  • The 5 year survival rate is approximately 80%, though survival rates can vary greatly depending on age, spread, recurrence, and subtype.
  • Medulloblastoma accounts for approximately 20% of all childhood brain tumors and 63% of intracranial embryonic tumors. These tumors can arise throughout childhood and into adulthood with an overall annual incidence of approximately 5 cases per 1 million in the pediatric population.
  • 75% of medulloblastomas occur in children under the age of 10, with incidence peaking in children 1–4 and 5–9 years of age.
  • Medulloblastoma is more common in males, affecting approximately 1.7 times more males than females, although sex predilection as well as age-specific incidence vary by subgroup.
  • Medulloblastoma is far more rare in adulthood, with a reported incidence of 0.05 cases per 100,000 population.
