Abstract:
Objective : To analyze the radiological and clinical factors that affect the recurrence of the meningioma.
Methods : The clinical and radiological aspects in 248 cases of meningiomas, which received operation during 1992 to 2000, were studied, only 166 cases are available. The factors were evaluated with univariate and multivariate analysis.
Results : With univariate analysis, tumor location,tumor size, tumor shape, edema, extent of resection, pathological grade, CT enhancement showed highly significance to recurrence of meningiomas. With multivariate analysis, tumor location, tumor shape,pathological grade, extent of resection, and CT enhancement showed significant danger to recurrence ofmeningiomas.
Conclusion : The main factors that affect the recurrence of meningioma patients are tumor location, tumor shape, extent of resection, pathological grade and CT enhancement.
