Summary
This study validated epilepsy surgery prediction tools on a large dataset. The Epilepsy Surgery Grading Scale (ESGS) and modified Seizure Freedom Score (SFS) accurately stratified patients for surgical outcomes and seizure freedom.
Area of Science:
- Neurology
- Neurosurgery
- Epileptology
Background:
- Epilepsy surgery prediction tools aid in patient selection.
- External validation is crucial for assessing tool generalizability.
Purpose of the Study:
- To externally validate existing epilepsy surgery prediction tools.
- To assess the tools' ability to stratify patients for surgery and seizure freedom.
Main Methods:
- A multicenter dataset of 1562 patients was analyzed.
- Epilepsy Surgery Grading Scale (ESGS), Seizure Freedom Score (SFS), and two versions of Epilepsy Surgery Nomogram (ESN) were applied.
- Patients were stratified into high, moderate, and low tiers for surgical outcome prediction.
Main Results:
- Concordance indexes for nomograms ranged from 0.56 to 0.69.
- ESGS, SFS, and ESNs accurately stratified patients for seizure freedom (p < .05).
- ESGS and modified ESN accurately stratified patients for receiving surgery (p < .05).
Conclusions:
- ESGS and modified ESN effectively stratify patients into tiers with varying chances of favorable surgical outcomes.
- These tools can assist in optimizing surgical candidate selection and resource allocation globally.
