MYCN amplification in spinal ependymoma: A five‐year retrospective study

Abstract

Spinal ependymoma with MYCN amplification is a newly recognized type of spinal ependymoma that is known to be associated with poor prognosis. Available studies on this relatively rare tumor type have observed that these tumors tend to disseminate along the spinal cord and behave aggressively with worse overall and progression‐free survival compared to the other types of ependymoma. In this study, we describe the clinical and histopathological features of spinal ependymomas in a single institution cohort with emphasis on those with MYCN amplification.
