Abstract
The expression of epidermal growth factor (EGFR) and c-erbB-2 protein were examined immunohistochemically in a total of 45 cases of bile duct cancer, and corelations between these expressions and clinicopathological variables were analyzed. The expression of EGFR and c-erbB-2 protein were observed in 17 of 45 cases (37.8%) respectively. There were no significant correlation between these expression and clinicopathological factors including the cell differentiation, tumor diameter, depth of invasion, lymph node involvement, stage, and vascular invasion. Five years survival rate in EGFR positive cases was 31.7% versus 61.7% in EGFR negative cases with a significant difference. Prognosis of patients with EGFR positive cancer was worse than those with EGFR negative cancer (p=0.04). Prognosis of patients with lymph node metastasis was also worse than those without lymph node metastasis (p=0.02).<br> These results suggest that expression of EGFR may serve as a useful biological marker as well as nodal involvement in the bile duct cancer.
