The most important finding was the statistically significant differences between the number of CD117 positive cases of IOPNs vs. that of other types of IPMN (p < 0.0001), and between the mean combined IHC scores of IOPNs vs. that of other types of IPMN (p < 0.0001). The gene discussed is KIT; the disease is pancreatic intraductal papillary-mucinous neoplasm.
