Outline of Research at the Start

既存治療に抵抗性を示す難治性消化器癌を対象として,(1)消化器癌におけるCD200を介する治療抵抗性獲得機構の解明,(2)CD200/CD200R経路阻害による既存癌治療の抗腫瘍増強効果の検証,(3)新規免疫チェックポイント阻害に対する抗腫瘍効果の検討,(4)ヒト化マウスを用いた新規集学的免疫治療法の前臨床試験を行う.これらの結果を基に,難治性消化器癌に対して,治療抵抗性克服による集学的癌免疫治療戦略の開発を目標とする.

Outline of Final Research Achievements

We analyzed factors associated with treatment resistance in refractory gastrointestinal cancers such as pancreatic cancer. We found that CD200 expression in tumor cells was significantly higher in patients treated with preoperative therapy than in those not treated preoperatively. Furthermore, we also found that the prognosis of the high CD200 expression group was poorer than that of the low expression group. The results also showed a significant inverse correlation with infiltrating T cells including CD4, CD8, and CD45RO.
Taken together, data suggest that CD200 is an important factor in the host immune system of various gastrointestinal cancers, and plays a critical role in treatment resistance. Therefore, CD200 may be useful as a therapeutic target molecule as well as biomarker. In addition, we succeeded in establishing a patient-derived xenograft mouse in vivo model from actual pancreatic cancer surgical specimens, which could be a useful therapeutic tool in the future.

Academic Significance and Societal Importance of the Research Achievements

膵癌等の難治性消化器癌では,化学療法が急速に進歩する今日においては,治療期間が長期化することと相まって,治療抵抗性獲得が大きな臨床課題となってきている.今回CD200が治療抵抗性獲得機構の機序の一つとして明らかとなった.今後CD200が治療抵抗性のバイオマーカーとなり,CD200標的治療が実現すれば,現行の癌治療成績は飛躍的に改善する可能性がある.さらに癌患者特異的に作成するin vivoモデルは真の個別化治療の推進につながる可能性もあり,特に治療抵抗性を示す癌患者にとっては意義が大きいものと思われる.盲目的に行う一元的な癌治療の回避は,医療経済に及ぼす影響も大きいものと期待できる.
