| Outline of Final Research Achievements |
Intraductal papillary neoplasm of bile duct (IPNB) is precursor lesion of invasive adenocarcinoma of bile duct. IPNBs are reported to be subdivided into 4 histologic subtypes (intestinal, gastric, oncocytic, pancreato-biliary), and to be heterogeneous with respect to their anatomical site along the biliary tree. In this study, IPNBs can be divided subgroup with respect to histologic similarities to intraductal papillary mucinous neoplasm of pancreas. By gene mutation analysis, some gene mutation showed association with histologic subtypes, subgroups, tumor location, and macroscopic mucin secretion. To investigate mechanisms of tumorigenesis and progression of IPNB, subtypes and other factors related to IPNB should be considered in future.
