<p><b>OBJECTIVE</b>To investigate the best combination of monoclonal antibodies for the diagnosis of hepatobiliary intraepithelial neoplasia and/or cancer.</p><p><b>METHODS</b>CK7, CK20, Villin, CEA, P53 and Ki-67 antigens were detected in the tissues of high-level hepatobiliary intraepithelial neoplasia and cancer by immunohistochemistry and the results were analyzed statistically.</p><p><b>RESULTS</b>Villin was 100% positive in hepatobiliary intraepithelial neoplasia and/or cancer, while 100% negative in the adjacent normal bile duct epithelium. The expression rate of CEA was significantly lower in high-level hepatobiliary intraepithelial neoplasia tissues than in the cancer tissues (P<0.05). Ki-67 indexes were significantly lower in most of the high-level hepatobiliary intraepithelial neoplasia than in the cancer tissue (P<0.01). P53 indexes were also lower in high-level hepatobiliary intraepithelial neoplasia (P<0.01).</p><p><b>CONCLUSION</b>Detection of multiple antigens (CEA, Villin, Ki-67 and P53) provides specific clues to the diagnosis of high-grade hepatobiliary intraepithelial neoplasia and/or cancer.</p>
