Multicenter StudySurgery for convexity meningioma: Simpson Grade I resection as the goal: clinical article.
Recently the relevance of Simpson resection grade as a prognostic factor for recurrence of WHO Grade I meningiomas was challenged, contradicting many previous scientific reports and traditional neurosurgical teaching. The objective of this study was to determine whether the predictive value of Simpson resection grade is outdated or remains valid with respect to meningioma recurrence and overall survival. ⋯ Simpson Grade I resection should continue to be the goal for convexity meningiomas.
