Outline of Final Research Achievements

We identified LOXL1 as a candidate gene responsible for peritoneal dissemination of gastric cancer and reported it in a paper. We clarified the clinical significance of the CYT score, which reflects the local immune environment of gastric cancer, and reported it in a paper. We experienced a rare adverse event of nivolumab therapy in gastric cancer, and reported it in a paper. Furthermore, we identified OSBPL3 as a novel oncogene, and clarified its biological and clinical significance in gastric cancer.

Academic Significance and Societal Importance of the Research Achievements

胃癌進行の責任遺伝子を同定することで、その根底にあるメカニズムを明らかにし、新たな胃癌の治療法と検査法の開発につながります。胃癌の予後改善に寄与することが予想されます。
また、胃癌における免疫療法が盛んに研究されていますが、その治療効果予測因子が少ない現状です。我々はCYT scoreが胃癌局所免疫を反映することを証明し、免疫療法の治療効果予測因子になりうることを提示しました。これも胃癌の予後改善に寄与することが予想されます。
