Descriptive epidemiology of ependymal tumours in the United States.

ABSTRACT:

Background

Ependymomas are rare primary gliomas that commonly affect both children and adults, but unique as survival is worse in children.

Methods

Data on brain and central nervous system primary malignant and non-malignant ependymal tumours from the Central Brain Tumor Registry of the United States analytic data set and primary malignant ependymal tumours from the SEER 13 registries research data file were used to evaluate incidence and survival, respectively.

Results

The 2004-2009 average annual age-adjusted incidence rate of ependymal tumours was 0.41/100,000. Spinal cord/cauda equina was the primary site at diagnosis for 50-60% of ependymal tumours in adult age groups in contrast to about 20% in children and adolescents. Ependymoma was the most frequent histology
