Medulloblastoma epidemiology and demographics

Introduction

Overview

Overview

Medulloblastoma is the second most common brain tumor among the pediatric population.[1] The overall age adjusted incidence rate of medulloblastoma is approximately 0.71 per 100,000 individuals in the United States.[2] The incidence of medulloblastoma decreases with age; the median age at diagnosis is between 5 to 7 years.[3] Males are more commonly affected with medulloblastoma than females. The male to female ratio is approximately 1.44 to 1.[2]

Epidemiology and Demographics

Epidemiology and Demographics

Prevalence

  • Medulloblastoma is the second most common brain tumor among the pediatric population.[1]
  • Medulloblastoma is considered a rare tumor among adults, as it comprises fewer than 2% of all brain tumors among that age group.

Incidence

  • The overall age adjusted incidence rate of medulloblastoma is approximately 0.71 per 100,000 individuals in the United States.[2]

Age

  • The incidence of medulloblastoma decreases with age; the median age at diagnosis is between 5 to 7 years.[3]
  • The molecular subgroup of medulloblastoma has an influence on the age of presentation such as:[4]
  • WNT medulloblastoma subgroup presents among older children
  • SHH medulloblastoma subgroup presents among infants and adults
  • Group 3 medulloblastoma presents among younger children
  • Group 4 medulloblastoma presents among younger children

Gender

  • The overall age adjusted incidence rate of medulloblastoma among males is approximately 0.84 per 100,000 individuals in the United States.[2]
  • The overall age adjusted incidence rate of medulloblastoma among females is approximately 0.58 per 100,000 individuals in the United States.
  • Males are more commonly affected with medulloblastoma than females. The male to female ratio is approximately 1.44 to 1.

Race

  • There is no racial predilection to medulloblastoma.[5]
