Outline of Research at the Start |
我々は、切除不能進行膵がんにおいて、FOLFIRINOX療法(FX)による重篤な好中球減少は生存期間の延長と有意に相関することを報告しており(Cancers.2018,10,454)、そのメカニズムとして、Myeloid derived suppressor cell(MDSC)の関与を考えた。MDSCsは未熟な骨髄細胞であり、がんや炎症により末梢血中に誘導され、強力な免疫抑制作用を示す。膵がん患者で末梢血中MDSC増加の程度が大きく、その関与が多いと考えられる。本研究では、FXが投与される膵がん患者の効果判定のバイオマーカーとして、好中球減少やMDSC濃度変化と治療効果の関係を明らかにする。

Outline of Final Research Achievements |
Patients with severe neutropenia may have decreased myeloid derived suppressor cells (MDSC), which may be an indicator of the efficacy of anticancer drugs. First, to establish a system for measuring MDSC concentration, we investigated conditions using three types of cultured human leukemia cells, HL60, NB4, and KG-1, and were able to isolate all cells as CD11b+CD14- CD33+ by flow cytometry analysis. In addition, severe neutropenia was used as a surrogate marker of MDSC decline and its association with overall survival (OS) was examined. Time-dependent Cox regression analysis with immortality time bias was performed in patients treated with trifluridine tipiracil hydrochloride and bevacizumab. Results showed that severe neutropenia was significantly associated with prolonged OS.

Academic Significance and Societal Importance of the Research Achievements |
本研究では、骨髄由来免疫抑制細胞(MDSC)濃度測定系の確立を行ったのちに、トリフルリジンチピラシル塩酸塩とベバシズマブ併用療法の重篤な好中球減少をMDSCの低下のサロゲートマーカーと仮定し、治療効果との関連を検討した。本研究で、ヒト検体を用いてMDSCを測定することはコロナ禍でできなかったが、時間依存性COX回帰分析を用いて、重篤な好中球減少と治療効果との関連を明らかにできたことで、重篤な好中球減少を指標にしたがん化学療法の治療効果予測の可能性を高めることにつながった。今後ヒト検体を用いて、MDSC濃度を調べることで治療効果の向上に大きく貢献できるものと考える。
