Brain tumors are now the most common cancer and cause of cancer-related death in children less than 15 years of age. They are the most common solid tumor in children – accounting for approximately 25% of all childhood cancers.
- Over 14% of brain and CNS tumor deaths in children under 14 are attributed to medulloblastoma.
- Approximately 350 patients are diagnosed each year.
- Approximately 60% of patients diagnosed are children or youth under the age of 15.
- There are an estimated 3,800 people living with medulloblastoma.
- The 5 year survival rate (including adults) is 72.1%, compared a median pediatric survival rate of just 3 years.
- 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.
