N2 - INTRODUCTION: Epilepsy occurs in 35-70% of patients with gliomas; glutamate plays a central role via AMPA-receptor activation, which is involved both in seizure activity and tumor growth. We conducted a retrospective study on brain tumor-related epilepsy patients (BTRE) treated with perampanel in add-on (PER) for 12 months, to evaluate efficacy and tollerability, according to real-life clinical practice. MATERIALS AND METHODS: Medical records of eleven patients (9 males, mean age 54 years) with glioma and epilepsy treated with PER in add-on, for inadequate seizure control or adverse events (AEs) from previous antiepileptic drugs (AEDs) therapy, were reviewed. Data collected included: tumor history, molecular factors, systemic therapy, type and number of seizures and concomitant AEDs, and AEs. RESULTS: After 12 months of PER therapy, five patients were seizure-free, 4 had a seizure reduction >/=50% and the seizure frequency was unchanged in 2 patients. Responder rate was 81.8%. Two patients reported AEs; PER dose was reduced only in the one case. The final median dose of PER was 7.3 mg/day. We didn't find statistically significant differences in the comparison between mean values pre, mean values post and the average of decreasing number of seizures related to: histology, presence/absence of chemotherapy, radiotherapy, progression disease, KPS, IDH1, MGMT. DISCUSSION: Despite the limitations due to small number of patients in a retrospective study, the high rate of responder and seizure-free patients suggest that PER could be a therapeutic option in BTRE. Prospective controlled studies are needed to confirm our data.
