Outline of Research at the Start

悪性髄膜腫はしばしばしば再発・転移を繰り返す、最も治療困難な頭蓋内腫瘍のひとつであり、新規治療法の開発が必要である。本研究では、①悪性化に関連する分子経路と②髄膜腫幹細胞 の2つを治療標的とし、悪性髄膜腫に対する新規治療法開発を目標とする。当院の悪性髄膜腫55症例を対象として、CGH法による染色体コピー数異常検索とがん関連遺伝子パネル検査を行うことにより、再発や生存期間と相関する染色体・遺伝子異常を検索する。新鮮腫瘍の初代培養を継続し、髄膜腫幹細胞株を樹立し、その特性を検索する。これらにより治療標的となりうる分子経路などが解明されれば、現有する培養株、マウス移植片において、治療効果を検討する。

Outline of Final Research Achievements

More than 20 atypical/anaplastic meningiomas and 8 grade 1 meningiomas without evidence of recurrence for more than 5 years were analyzed for expression profiling and mutation profiling (cancer gene panel test) with the aim to classify atypical/anaplastic meningiomas according to molecular pathway correlated with patient prognoses. Preliminary results showed that atypical/anaplastic meningiomas were classified into 3 groups by hierarchical clustering based on expression profiling. In addition, we have established a malignant meningioma cell line and its xenograft in mice that apparently has stem cell property. Efficacy assays are being performed by mono- or combination therapy with molecular targeted drugs according to mutation profiles in 2 malignant meningioma cell lines; the above mentioned one established by ourselves and a commercial one, with the aim to develop the most efficacious drug combination in each of the molecular groups of atypical/anaplastic meningiomas.

Academic Significance and Societal Importance of the Research Achievements

WHO分類Grade 2/3の異形性・退形成性髄膜腫(悪性髄膜腫, 国内で約500人/年発生)は、手術および放射線治療を行っても高率に局所再発あるいは頭蓋内・外転移を繰り返す、最も治療困難な脳腫瘍のひとつであり、有効な新規治療法を開発することが急務である。現状では、たとえ保険診療がん遺伝子パネル検査で治療標的となる遺伝子異常が発見されても、施行可能な治療は、NCCH1901試験等への参加による分子標的薬単剤治療である。悪性化メカニズムによる悪性髄膜腫の分類、そしてその各群に対する適切な治療薬の組み合わせが確立されれば、先進医療などの枠組みにより、新たな治療法が提供できる可能性がある。
