    Abstract:
    Anomalous junction of the pancreaticobiliary duct (AJPBD) is thought to be an important risk factor for gallbladder carcinoma in Japan. We have reported the characteristic pathology, cellular kinetics, and gene mutations to clarify the mechanism of carcinogenesis in gallbladder mucosa with AJPBD. A comprehensive review of the literature was undertaken, with referencing of major articles on the subject. A sequence of hyperplastic changes, with a corresponding increase in cellular kinetics with progression through dysplasia to carcinoma is important in carcinogenesis of gallbladder mucosa with AJPBD. p53 mutations may contribute to the transition from premalignancy to malignancy in the early stage of carcinogenesis of the gallbladder mucosa, regardless of the presence of AJPBD. The specific mutation of GGT-to-GAT in codon 12 of K-ras may play an important role in carcinogenesis of gallbladder mucosa with AJPBD.
