| Research Abstract |
It is a well-known fact that oligosaccharide structures are dramatically changed in carcinogenesis including malignant transformation.N-Acetylglucosaminyltransferase V (GnT-V) enhances the malignant behaviors of carcinoma cells such as proliferation, invasion and metastasis. In this study, the immunohistochemical expression of GnT-V was studied in the tissue sections of gallbladder carcinoma and those of intrahepatic cholangiocarcinoma. The results revealed that in gallbladder carcinoma, the post-surgical prognosis was significantly poorer in the cases of positive staining than in those of negative staining and, moreover, that the post-surgical recurrence rate tended to be higher in the former than in the latter. However, in cholangiocarcinoma, the immunohistochemical expression of GnT-V did not give any clinicopathological significance. A molecular-targeting therapy against GnT-V may be useful in the treatment of biliary tarct cancers
