Background and Objectives: The prognosis of biliary tract carcinoma remains poor despite aggressive surgical approaches. Factors contributing to the dismal outcomes include the high rates of lymph node (LN) metastasis in advanced biliary tract carcinomas. In particular, paraaortic LN metastasis affects the indication for resection of biliary tract cancers, because a failure of surgical resection to improve the prognosis has been reported in cases showing paraaortic LN metastasis. Although the size of LNs is one of the major factors distinguishing positive from negative nodes, size is not a reliable indicator of metastasis because many small LNs contain metastasis and the quantity of cancer cells in metastatic LNs is variable. In biliary cancers, few studies have addressed the histological features of LN metastasis. Therefore, this study analyzed the detailed morphological features of metastatic LNs in biliary cancers.
