Effects of ventricular entry on patient outcome during glioblastoma resection

Abstract

VE was well tolerated, with postoperative complications being rare events. There was no increase in leptomeningeal spread or distant parenchymal recurrence in patients with VE. Finally, although survival was worse for patients with preoperative subependymal disease, VE did not change survival for patients with tumors contacting the ventricle. Therefore, VE during GBM resection is not associated with adverse patient outcomes and should be used by surgeons to enhance extent of resection.■ CLASSIFICATION OF EVIDENCE Type of question: therapeutic; study design: retrospective cohort; evidence: class II.
