Outline of Research at the Start

「オキサリプラチンを用いた逐次療法と併用療法にBevacizumabを加え比較検討を行った無作為ランダム化第III相臨床試験(C-cubed study)」の参加者から得られた大腸癌組織を対象に、Genetic/Epigenetic変異、TIL/HLA class I発現の有無等、免疫疲弊の解析を行い、大腸癌進展速度の推定が可能となるMolecular subtypeの同定を試みる。

Outline of Final Research Achievements

In our investigation, we propose that MGMT methylation has potential to be a predictive biomarker for recurrence in pStage III colorectal cancer, but not as a prognostic or therapeutic effectiveness marker for unresectable colorectal cancer under chemotherapy. This contradiction is explained by our hypothesis that, while tumors with MGMT methylation experience heightened immunogenicity and augmented antitumor effects under chemotherapy, advanced stages of the cancer may induce an immune exhaustion. Upcoming Mutational Signature analyses will probe further into this observation, specifically whether a noticeable increase in G to A transitions post-chemotherapy in MGMT-methylated tumors may indicate a potential efficacy of subsequent immune checkpoint inhibitor treatments.

Academic Significance and Societal Importance of the Research Achievements

本研究では、MGMTメチル化がpStage III大腸癌の再発予測マーカーとなる可能性を示し、個々の患者の再発リスクを早期に評価する新たな道筋を開いた。しかし、切除不能大腸癌の化学療法に対する予後・効果予測マーカーとはならず、この矛盾が免疫疲弊と関連する可能性を示唆。これは癌治療への新規アプローチを促進し、特にMGMTメチル化を有する腫瘍における化学療法後の免疫チェックポイント阻害剤の有効性を予見する新たな可能性も示唆している。
