Analysis of Clinical Parameters Affecting Recurrence of Meningiomas

Objective: To provide reasonable evidences of the clinical factors that affect the recurrence of meningioma so as to diagnose and treat the recurrence of meningioma earlier. Methods: Clinical features in 83 cases of meningiomas, which were operated during 1993-1997, were studied retrospectively. The factors were evaluated with univariate and multivariate analysis. Results: With univariate analysis, four factors highly related to the recurrence of meningiomas. They were tumor size, tumor shape, extent of resection and pathological grade. Pathological grade, extent of resection and tumor shape were risk factors of meningiomas recurrence with multivariate analysis. Conclusion: The main factors that affect the recurrence of meningioma patients are pathological grade, extent of resection and tumor shape.
