Abstract

The expression of epidermal growth factor (EGF) and its receptor (EGFR) was studied immunohistochemically in fifty-seven Chinese patients with primary invasive ductal carcinoma (IDC) of the pancreas. The frequency of expression of EGF and EGFR was 73.7% and 68.4%, respectively. The frequency of their co-expression was 61.4%. No significant relationships were seen between the expression of EGF and its receptor and the patients' age, gender, site of the tumor, stage, and grade. Positive co-expression of EGF and EGFR was significantly associated with the poor prognosis. The median survival of the EGF(-)EGFR(-) group for 17.2 months was longer than that of the EGF(+)EGFR(+) group for 9.7 months (p = 0.02), as well as that of the other groups of EGR(+)EGFR(-), EGF(-)EGFR(+), and EGF(+)EGFR(+) for 9.9 month (p = 0.03). These results suggested that EGF and EGFR were frequently expressed in Chinese patients with IDC of the pancreas. Their co-expression may be a useful prognostic indicator for pancreatic cancer.
