KRAS and pancreatic intraductal papillary-mucinous neoplasm: In contrast, KRAS mutations have been reported in resected tissues from both IPMN and PDAC, with respective detection rate ranges of 48–81% [12], [16] and 78–100% [7], [9], [12], indicating that KRAS mutations can be associated with both diseases; however, the mutation rate has been somewhat higher in PDAC.
