The aim of this study was to analyze metabolite differences in pancreatic cancer and diabetic patients, to better diagnose these diseases. Gas chromatography-mass spectrometry was used to evaluate the metabolomic differences in blood samples of 50 pancreatic patients, 50 diabetic patients and 50 healthy people. Metabonomic data was analyzed with primary component analysis and discriminant analysis. The results show that pancreatic cancer patients, diabetic patients and healthy people can have significantly distinct metabolite profiles. Upregulated metabolites in the serum of the diabetic group included sugars (glucose, fructose), cholesterol, tyrosine and phosphoric acid and other substances, and down-regulation was observed in lactic acid, glycine, alanine, glutamine, proline, citric acid and other substances. It is indicated that identification of the most common changes in specific markers between the two diseases, can provide a new perspective and experimental basis for a better understanding of the metabolic differences and the pathogenesis of the two diseases in future. The present study sheds new light on the diagnosis of pancreatic cancer and diabetes.
