Methods:In this hospital-based retrospective study, patients with brain tumors and drug-resistant epilepsy, which is defined as the failure of two tolerated and appropriately chosen antiepileptic drugs (whether as monotherapies or in combination) to achieve and alleviate sustained seizure freedom, were recruited. These patients underwent a thorough pre-surgical evaluation in an Epilepsy Monitoring Unit (EMU) before deciding to undergo surgical intervention according to an epilepsy case management conference.Results: One-hundred patients (including 45 children) with brain tumors were included in this study (male: female = 3:2). Most of the patients (93) had G/GNT. No significant differences in outcome were observed among sex, age, or histopathological categories. However, during the first year after epilepsy surgery, most of the low-grade G/GNT cases showed favorable outcomes based on ILAE classes 1 and 2 (61.3% and 9.7%, respectively), whereas high-grade gliomas and meningothelial tumors showed outcomes of ILAE class 1 (40% and 100%, respectively).
Conclusion:Post-epilepsy surgical outcomes of different brain tumors have been achieved with favorable outcomes in children and adults with low-grade gliomas and meningiomas. Thus, pre-surgical evaluation in EMU is highly recommended to enhance better post-epilepsy surgical outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
