Abstract: Objective To predict recurrence rate by analysis of the literature to determine the recurrence rate ranges of meningiomas following surgery or radiation. Methods This search collected 13 studies that met all criteria for inclusion and a total of 2048 patients included in the assessment. Results Recurrence rates of meningiomas ranged from 0.00 to 2.36 per 100- person- years for WHO grade Ⅰ meningiomas；and from 7.35 to 11.46 per 100- person- years for WHO grade II meningiomas. From the literature of 14 studies，it was suggested that reported recurrence rates were variable and complicated by the heterogeneity of study populations. WHO grade Ⅱ meningiomas generally had a higher recurrence rate than WHO grade Ⅰ ，when controlling for time of diagnosis. Conclusion Our findings suggest that he recurrence rate of meningioma is difficult to predict accurately.There was a need for more rigorous reporting of recurrence rates，WHO grade，and Simpson grading for individual patients to determine a robust mean of recurrence across WHO grades.
