In this study, we performed metabolome analysis of esophageal cancer patients, and the aim of this study was to discover the biomarkers that are useful for early detection of esophageal cancer. As a result, we found the 17 metabolites that were significantly changed by the pathogenesis of esophageal cancer by metabolome analysis using gas chromatography/mass spectrometry. By lipid metabolome analysis using liquid chromatography/mass spectrometry, we discovered the 47 lipid metabolites with the significant alterations, and by cation/anion metabolome analysis using liquid chromatography/mass spectrometry, we found the 13 metabolites with the significant alterations. These significantly-changed metabolites may be candidates for esophageal cancer biomarkers.
