This study conducted a retrospective analysis of patients who underwent excision of insular high-grade gliomas at three regional neurosurgical centers in the UK, showing that surgery is safe and results in effective postoperative seizure control.
-BACKGROUND: The insular cortex is an eloquent island of mesocortex surrounded by vital structures making this region relatively challenging to neurosurgeons. Historically, lesions in this region were considered too high risk to approach given the strong chance of poor surgical outcome. Advances in recent decades have meant that surgeons can more safely access this eloquent region. Seizure outcome after excision of insular low-grade gliomas is well reported, but little is known about seizure outcomes after excision of insular high-grade gliomas. -METHODS: A retrospective analysis was performed of all patients presenting with new-onset seizures during 2015e 2019 who underwent excision of an insular high-grade glioma at 3 regional neurosurgical centers in the United Kingdom. -RESULTS: We identified 38 patients with a mean (SD) age of 45.7 (15.3) years with median follow-up of 21 months. At long-term follow-up, of 38 patients, 23 were seizure-free (Engel class I), 2 had improved seizures (Engel class II), 6 had poor seizure control (Engel class III/IV), and 7 died. -CONCLUSIONS: Excision of insular high-grade gliomas is safe and results in excellent postoperative seizure control.
