Outline of Research at the Start

低容量頻回投与に基づく化学療法(Metronomic chemotherapy: メトロノーム化学療法)は、術前や術後に補助療法として用いることで、口腔癌患者の生存率が有意に改善することを申請者を含む多くの研究者が報告している。申請者は、、高分化型腫瘍はメトロノーム化学療法耐性であることを示している。本研究の学術的な問いは、メトロノーム化学療法耐性機構のメカニズムをRTKの活性化という視点から解明することである。

Outline of Final Research Achievements

Metronomic chemotherapy is defined as a high-frequency low-dose schedule of chemotherapy drug administration. The response rate of well-differentiated OSCC to metronomic chemotherapy was significantly lower. We investigated differences in molecular profiles between poorly or moderately differentiated head and neck squamous cell carcinoma (HNSCC) and well-differentiated HNSCC from patients with HNSCC TCGA data. An upstream regulator analysis correlated with EphA4 expression identified pathways associated with decreased mTORC1 signaling and T cell activation, including TCR, CD3, CD28, and CD40LG. Plasmacytoid dendritic cell and CD8+ T cell numbers were higher in the microenvironment of poorly or moderately differentiated HNSCC than in that of well-differentiated HNSCC. Moreover, KYL used with chemotherapeutic drugs synergistically increased cancer cell death.

Academic Significance and Societal Importance of the Research Achievements

我々は、bleomycin 併用S-1 による術前メトロノーム化学療法のphase I/II 試験の結果を学術誌上にて報告した(Kina S, et al. Eur J Pharmacol. 2023)。上記化学療法による重篤な副作用は観察されなかった。約半数の患者で、組織学的に腫瘍が完全に消失しており、そのような患者集団では、外科切除を最初に行った患者群と比較して生存率が有意に高くなっていた。高分化型腫瘍は、抗がん剤耐性を示した。高分化型腫瘍周囲では、免疫細胞が枯渇しており、EphA4 が活性化していた。メトロノーム化学療法は、腫瘍免疫に関して働きかけていることが強く示唆された。
