Mutation Status and Epithelial Differentiation Stratify Recurrence Risk in Chordoid Meningioma—A Multicenter Study with High Prognostic Relevance

Abstract excerpt

Chordoid meningioma is a rare WHO grade II histologic variant. Its molecular alterations or their impact on patient risk stratification have not been fully explored. We performed a multicenter, clinical, histological, and genomic analysis of chordoid meningiomas from 30 patients (34 tumors), representing the largest integrated study to date. By NHERF1 microlumen immunohistochemical detection, three epithelial...
