Based on a review of 800 personal cases of meningioma surgery as mentioned in the last section, this time we did another study in order to determine the factors that influence outcome in meningioma surgery. In summary these important factors include the following:
Internal factor (inherent to patients/tumors):
Co-morbidity (patient’s health status)
Surgeon’s experience (i.e. the “learning curve” effect)
Using the first letters of the first five factors (Co-morbidity, Location, Age, Size, Symptoms), I have come up with an acronym – “CLASS”- for teaching residents and young neurosurgeons the important factors that determine outcome in meningioma surgery. Also, utilizing these outcome factors, I have developed the “CLASS” algorithmic scale for patient selection in meningioma surgery.
