The [[incidence]] of brainstem gliomas is estimated to be 0.05 - 0.1 cases per 100,000 individuals in USA. A [[bimodal distribution]] by age is noted with peak [[Incidence|incidences]] rates in children and older adults. The [[prevalence]] and [[incidence]] of brainstem gliomas do not vary by either race or gender.
CNS tumors vary in incidence by age, sex, ethnic group, and country, and also over time. How much of this variation is due to artifactual influences or etiologic differences has been the subject of many debates.

===Frequency===


In the US, brainstem gliomas have been reported to make up 2.4% of all intracranial tumors in adults and 9.4% of intracranial tumors in children. Brainstem gliomas account for approximately 10-20% of all childhood brain tumors. The incidence in adults is lower than that in children younger than 16 years. A tendency for brainstem gliomas to follow a more indolent course in adults than in children has been noted; in adults, these tumors are more likely to be low grade and remain localized.

Bimodal age distribution has been noted, with a peak incidence in the latter half of the first decade of life and a second peak in the fourth decade.
===Race===
Approximately three fourths of patients are younger than 20 years.
There is no racial predilection to the development of brainstem glioma.
Neoplasms of the brain stem have been identified in children younger than 1 year.

Overview

The incidence of brainstem gliomas is estimated to be 0.05 - 0.1 cases per 100,000 individuals in USA. A bimodal distribution by age is noted with peak incidences rates in children and older adults. The prevalence and incidence of brainstem gliomas do not vary by either race or gender.

Epidemiology and Demographics

Incidence

The incidence of brainstem gliomas is 0.05 - 0.1 per 100,000 individuals per year.

Age

A bimodal distribution by age is noted with peak incidence rates in children (aged 7-9 years; most common) and among older adults (aged 30-40; rare) is seen.[1] The diffuse infiltrating type occur most often in school-age children where they are responsible for the greatest number of childhood deaths from primary brain tumors. [3]

Gender

There is no gender predilection to the development of brainstem glioma.[1]

Race

There is no racial predilection to the development of brainstem glioma.
