Outline of Final Research Achievements

In this study, we focused on PET-positive lung cancer and searched for markers that can be used for early diagnosis. By orally administering 13C glucose to patients with curatively resectable PET-positive lung cancer and comparing samples before and after administration, before and after surgery, we comprehensively investigated 13C glucose-derived metabolites specifically metabolized by lung cancer cells. It was measured. As a result, 15 types of 13C-glucose-derived candidate metabolites were found from accurate mass data using preoperative specimens from lung cancer patients. We constructed a new analysis system for each metabolite candidate marker and verified it as a cancer diagnostic marker. In the future, we will conduct comparative studies with various other cancers to clarify the specificity of lung cancer.

Academic Significance and Societal Importance of the Research Achievements

本研究では、肺がん特異的なバイオマーカーの開発を行った。体内で肺がん細胞は普通の細胞と代謝が異なること、グルコースを多く取り込むことが知られている。そこで、グルコースを構成する炭素分子に目印(C12→C13)をつけてヒトに投与し、尿から検出される代謝物を網羅的に解析することで、肺がん特異的なバイオマーカーをスクリーニングした。これまでに15種の候補物質を同定しており、今後、他のがん種での比較を行う予定である。
