Diagnosis of Pancreatic Cancer by Purine Metabolite (Hypoxanthine, Xanthine) in Urine

"* Collect urine from the patient to measure urinary hypoxia, xanthine concentration.~* Hypoxic acid, xanthine analysis in urine using High Performance Liquid Chromatography (HPLC).~* After that, hypoxanthine and xanthine will be analyzed using purine metabolite analysis reagents.~* Compare the cutoff of the metabolic value of Pancreas cancer clarified in the existing research and the value of the sample."
