Overcoming Chemoresistance of Pediatric Ependymoma by Inhibition of STAT3 Signaling

Translational Oncology, 2015
The long-term clinical outcome of pediatric intracranial epepdymoma is poor with a high rate of recurrence. One of the main reasons for this poor outcome is the tumor’s inherent resistance to chemotherapy. Signal transducer and activator of transcription

Supratentorial Anaplastic Ependymoma Mimicking an Extra-Axial Tumor: A Case Report

대한영상의학회지, 2017
Ependymoma is a glioma which arises from the ependymal cells lining the ventricle and the central spinal canal. It commonly occurs in the brain outside the ventricle in the supratentorium, in case of a supratentorial ependymoma.

Histology and Anatomic Site in Ependymoma [PDF]

, 2013
Ependymomas originate in posterior fossa (PF), supratentorial (ST) or spinal cord (SC) compartments. At present, grading schemes are applied independent of anatomic site.

Trisomy 19 ependymoma, a newly recognized genetico-histological association, including clear cell ependymoma

, 2007
Ependymal tumors constitute a clinicopathologically heterogeneous group of brain tumors. They vary in regard to their age at first symptom, localization, morphology and prognosis. Genetic data also suggests heterogeneity.
