Despite the availability of clinical and pathologic parameters for prognostic prediction prognosis, the behavior of each meningioma may be difficult to predict.

The presence of G2\/M\u2010phase and S+G2\/M\u2010phase fractions were analyzed and correlated with the proliferation index of Ki\u201067 and the World Health Organization grading. The check point of G2\/M\u2010phase fraction, cyclin B, and pCdk1 (Y15), were analyzed by Western blotting.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Our results showed that there were significant differences in Ki\u201067, G2\/M\u2010phase, S+G2\/M\u2010phase fractions, and cyclin B between benign and atypical\/anaplastic meningiomas. The optimal cutoff point of G2\/M\u2010phase and S+G2\/M\u2010phase fractions were 5.12 and 7.52%, respectively, and this can be used to discriminate those cases with benign or atypical\/anaplastic meningiomas. Besides, both the G2\/M\u2010phase and S+G2\/M\u2010phase fractions were correlated well with Ki\u201067 and the histopathological features such as focal necrosis, infiltration of dura mater and mitotic activity. In addition, the occurrence of tumor recurrence and patient age were correlated to the G2\/M\u2010phase and S+G2\/M\u2010phase fractions, respectively. The G2\/M\u2010phase and S+G2\/M\u2010phase fractions, however, did not correlate well with histologic invasion to adjacent bone, sinus, or brain
