On the other hand, Walter et al demonstrated that serum FAS was similarly elevated in pancreatic cancer patients, patients with intraductal papillary mucinous neoplasms and patients with chronic pancreatitis compared with healthy controls, indicating that FAS detection cannot be used for distinguishing pancreatic cancer patients from patients with other pancreatic diseases (18). Here, FAS is linked to pancreatic intraductal papillary-mucinous neoplasm.
