Predictive Factors for Survival in Aggressive Meningiomas

Analysis of Predictive Factors for Overall and Progression-free Survival After Neurosurgery for Atypical or Anaplastic Meningioma

The investigators plan to collect clinical and molecular data, including ICH, PCR, NGS and methylome, from patients operated on for grade 2 or grade 3 meningioma. The purpose of the study is to identify reliable and easy-to-assess predictive factors for recurrence and survival after surgery.

Inclusion Criteria:

1. Patient operated for atypical (grade 2) meningioma; or
2. Patient operated for anaplastic (grade 3) meningioma;
3. Timeframe for surgery, 1999-2019

Exclusion criteria

1) Patient lost at follow-up
