脳腫瘍研究
診療において正確で高度な画像誘導手術を行うためナビゲーションシステムや覚醒下開頭術、神経内視鏡手術、電気生理学的モニタリング技術、蛍光診断技術(5-ALA)、光線力学療法(PDT)等の最先端の脳腫瘍手術を行い、放射線・化学療法等の補助療法を含めた集学的治療を行っています。しかし、脳腫瘍のうち最も悪性度の高い神経膠腫(グリオブラストーマ)においては、集学的治療を施しても生存期間中央値は約2年と極めて予後不良です。その原因としてグリオブラストーマは浸潤性が高いため、完全に摘出するのは難しく、治療に難渋します。この状況をなんとか克服するため、各種の新規治療法の開発に向けて、他大学研究機関や学内医工連携研究を行っています。
近年、連携研究先(應義塾大学医学部内先端医 科学研究所遺伝子制御研究部門、佐谷教授ら)において確立された浸潤性の高いグリオブラストーマに近いマウスグリオーマ幹細胞移植脳腫瘍モデルを用いて超音波療法 (SDT)と薬物併用により抗腫瘍効果が増強された(左下図)ことから、産学連携研究に発展させ、反復可能なSDTの開発計画を準備しています。一方、脳腫瘍近傍に発現するchemokines(CCL2, CxCL10)(右下図)およびその受容体(CcR2, CcR10)の増加が脳腫瘍増大に関与し、その抑制が抗腫瘍効果に有用であることを見出し、医工連携研究により、創製化合物による治療効果の評価も継続しています。
