Maillo et al developed a prognostic score for patients with meningioma. This can help identify patients at a significant risk for recurrence. The authors are from Hospital Universitario de Salamanca and University of Salamanca in Spain.
Parameters:
(1) age of the patient in years
(2) WHO histologic grade
(3) numerical abnormalities (additions or deletions) in chromosome 14

total score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 3
• The higher the score the lower the probability of 5 year relapse free survival.
