Analysis of 120 surgical cases with convexity meningioma / 中国医师进修杂志

ABSTRACT

Objective To analyze the patients with convexity meningioma with respect to pathological factors leading to recurrence, surgical technique, and complication. Methods The data of 120 surgical cases of convexity meningioma were retrospectively reviewed. Statistical analysis were performed by SPSS 17.0 with method of Kaplan-Meier survival analysis. Results The 30-day mortality was 0. The pathology of the tumors was benign in 105 cases (87.5%), atypical meningioma in 12 cases (10.0%), and anaplastic/malignant meningioma in 3 cases (2.5%). In 8 cases designated benign, there were borderline atypical features. Two cases of benign tumor recurred whose pathology involved tumors with borderline atypia.Conclusions Patients with convexity meningioma should be actively operated, and Simpson Ⅰ resection must be performed to the best of ability whether the tumors are benign or malignant. Further postoperative adjuvant treatment will be implemented or not according to the histopathological types of the tumors. Although there are many factors of recurrence for convexity meningioma. The range of surgical resection and pathological types are still the important causes for recrudescence.
