Clinical Significance of GNAS Mutation in Intraductal Papillary Mucinous Neoplasm of the Pancreas With Concomitant Pancreatic Ductal Adenocarcinoma

Abstract

Distinct PDACs frequently develop in the pancreas with gastric type IPMN without GNAS mutations. Duodenal fluid DNA test would predict the GNAS status of IPMN, whereas the detection of the gastric subtype using noninvasive test remains to be determined.
