Progression-Free Survival and Factors Associated with Postoperative Recurrence in 126 Patients with Atypical Intracranial Meningioma.

Objective: Atypical meningioma has a higher recurrence rate than benign meningioma. The mainstay of treatment is surgery with or without radiation therapy (RT). The objective of this study was to investigate progression-free survival (PFS) and factors associated with postoperative recurrence in patients with atypical meningioma.
