| Research Abstract |
The followings are the main results and contributions. Intraductal papillary neoplasm of bile duct (IPNB) shares many features of intraductal papillary mucinous neoplasm of pancreas, particularly main duct type, such as gross and imaging features and histologies. IPNB are classified into the pancreatobiliary type, intestinal type, gastric type and oncocytic type, and these four types show characteric features. During the development and progression of IPNB, p53 and p16 are significantly involved, and MMP7 plays an important role in the progression of IPNB. These issues on IPNB have been discussed in several meetings in Japan and also USA, and IPNB has been accepted as a disease entity in biliary tract tumors. Furthermore, IPNB has just introduced as a disease entity and preneoplastic lesion of cholangiocarcinoma in WHO blue book on Gastrointestinal tract tumor, 2010, and this topic is now discussed and studies worldwide.
