Keywords胆管癌 / 腫瘍免疫
Outline of Annual Research Achievements

1. これまでの蓄積サンプルに加えて、岡山大学病院肝胆膵外科にて行われた肝内胆管癌切除症例より組織サンプルを収集・保存し、DNA抽出を行った。既に確立されている血中メチル化DNA/miRNAの解析とともに、前向きに肝内胆管癌患者の術前・術後血液サンプルの収集に向けて準備を進めている。
2. 腫瘍・宿主免疫応答評価として、各種免疫栄養指標の評価を算出し、再発予後・生存予後について比較検討。
また肝内胆管癌切除標本より、腫瘍局所における腫瘍関連免疫反応を評価し、全身免疫栄養指標との関連性を検討することで、末梢血液における免疫指標の意義 を検討している。これまでの解析より、術前の免疫栄養指標は鋭敏に肝内胆管癌の切除予後を反映することを明らかにした。更にCD8/Foxp3からなる腫瘍On-siteでの免疫栄養疲弊の評価が切除予後規定因子となることを認めており、今後免疫栄養指 標との関連性について解析していく予定である。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

サンプル集積・解析について、順調にDataは蓄積されつつある。
Liquid biopsyの候補となる循環miRNA候補と臨床経時的data(腫瘍マ ーカーなど血液検査、各種画像検査所見)との比較検討を将来的に行うべく準備は順調に進 んでいる。

Strategy for Future Research Activity

腫瘍病勢評価の指標となり得るLiquid Biopsyの検査手技を確立するために、蓄積された経時的循環miRNAの測定dataと、従来既存の腫瘍マーカー推移、CT画像変 化とを比較検討していき、循環miRNAの意義を証明する。具体的には、循環miRNAと既存腫瘍マーカーとの精度の比較を予定している。今後は、Validation cohortとして実験結果を再度検証していくために切除標本・血液サ ンプルを幅広く集積していく予定である。

Causes of Carryover

(理由) 肝内胆管癌サンプル収集、及びGenetic/Epigenetic解析を行う中で、リアルタイムPCR、細胞培養に用いる試薬・抗体購入を予定していたが、予定より も少ない量で順調に結果が得られたために、次年度繰越研究費が発生した。
(使用計画)
今後、既存札細胞剤・分子標的薬併用についての基礎実験、及びin vivo実験実施にあたり費用がかかるために、繰越研究費を充てる予定である。
