Early Postoperative Adjuvant Radiotherapy Versus Active Monitoring After Gross Total Resection for Atypical Meningiomas: Factors Associated with Early Recurrence.

Aim: To investigate the predictors of recurrence after gross total resection (GTR) that require early adjuvant radiotherapy upfront rather than at initial recurrence of atypical meningiomas (AMs).

Material And Methods: A retrospective study of gross totally resected AMs was conducted in a tertiary care center within ten years. The clinical, radiological, and pathological parameters were analyzed statistically, and the factors associated with recurrence after GTR were determined with univariate analysis.
