Pathologic predictors of local recurrence in atypical meningiomas following gross total resection

Local recurrence following gross total resection of atypical meningiomas is difficult to prognosticate. Pathologic predictors could help risk stratify patients. This retrospective analysis assesses various pathologic variables, including the 2016 World Health Organization grade II criteria, through central review by a neuro-pathologist. Ki67 proliferative index and mitotic number strongly predict for local recurrence following gross total resection and 30.3% of patients locally recur by 3 years.
