KRAS and pancreatic intraductal papillary-mucinous neoplasm: KRAS mutations are common in gastric-type IPMNs and occurs in 70–80% of these lesions, which is significantly higher than the rate seen in other IPMN subtypes.[29] Interestingly, a recent report on KRAS mutation analysis using NGS also reported a similarly high KRAS mutation rate of 83.3% in patients with IPMNs, although the exact histologic subtypes of these IPMNs are unknown.
