Outline of Final Research Achievements

We believe that evidence from various studies may support that administration of antiepileptic drugs lead to survival benefit for patients with malignant glioma. As a basic research experiment (study) on the administration of antiepileptic drugs in malignant glioma, in this study, using malignant glioma cell lines (6 types: A-172, AM-38, T98G, U-138MG, U-251MG, and YH-13), we investigated the antitumor effect of antiepileptic drugs (4 standard antiepileptic drugs: carbmazepine, sodium valproate, levetiracetam, perampanel) and their mechanisms of antitumor effect. As a result, in the treatment of malignant glioma cells, perampanel displayed a cell growth inhibitory effect, induced apoptosis, and suppressed cell migration ability. Therefore, perampanel may be more beneficial than other antiepileptic drugs for malignant glioma patients.

Academic Significance and Societal Importance of the Research Achievements

抗てんかん薬における悪性神経膠腫に対する抗腫瘍効果を検討した報告はあるが、多剤を比較検討した報告は少ない。また、悪性神経膠腫は高い増殖能と浸潤能のために予後不良とされるが、抗てんかん薬における抗腫瘍効果として細胞遊走能・浸潤能を検討した報告もほとんどない。さらに、悪性神経膠腫に対する標準的化学療法薬であるTMZとの相乗的な抗腫瘍効果の検討を行った報告も少ない。今回の検討の結果、悪性神経膠腫に対する治療において、perampanelは細胞増殖抑制効果やアポトーシスの誘導、細胞遊走能の抑制が認められ、他の抗てんかん薬(CBZ, VAP, LEV)と比べ抗腫瘍効果として有益に働く可能性が示唆された。
