New Metabolite-Based Diagnostic Test Could Detect Pancreatic Cancer Early
A new diagnostic test, developed in Japan, that uses a scientific technique known as metabolomic analysis may be a safe and easy screening method that could improve the prognosis of patients with pancreatic cancer through earlier detection. Japanese researchers examined the utility of metabolomic analysis of serum as a diagnostic method for pancreatic cancer and then validated the new approach, according to study results published online on March 29, 2013 in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. "Although surgical resection can be a curative treatment for pancreatic cancer, more than 80 percent of patients with pancreatic cancer have a locally advanced or metastatic tumor that is unresectable at the time of detection," said Masaru Yoshida, M.D., Ph.D., associate professor and chief of the Division of Metabolomics Research at Kobe University Graduate School of Medicine in Kobe, Japan. "Conventional examinations using blood, imaging, and endoscopy are not appropriate for pancreatic cancer screening and early detection, so a novel screening and diagnostic method for pancreatic cancer is urgently required." Using gas chromatography mass spectrometry, the researchers measured the levels of metabolites in the blood of patients with pancreatic cancer, patients with chronic pancreatitis, and healthy volunteers. The scientists randomly assigned 43 patients with pancreatic cancer and 42 healthy volunteers to a training set and 42 patients with pancreatic cancer and 41 healthy volunteers to a validation set. They included all 23 patients with chronic pancreatitis in the validation set.
