National Patterns of Care in the Management of World Health Organization Grade II and III Spinal Ependymomas.

Background: Spinal ependymomas are rare, with an incidence of 1 per 100,000. Given the paucity of data for higher grade II and III disease, the management and patterns of care require further investigation.

Methods: Our study of 1345 patients with higher-grade spinal ependymoma used χ tests and simple and multivariable logistic regression models to assess demographic and clinical factors associated with therapy.
