Immunohistochemical analysis for the epidermal growth factor receptor (EGFR), EGF and transforming growth factor-alpha (TGF-alpha) was performed in 87 human pancreatic carcinomas. Expression frequencies for EGFR, EGF, and TGF-alpha were 43%, 46% and 54%, respectively. Coexpression of the receptor and at least one of its ligands occurred in 38% of the tumors, and correlated with large tumor size, advanced clinical staging, and decreased survival period. In situ hybridization revealed that the respective mRNAs were also overexpressed in the carcinomas. These findings suggest that coexpression of EGFR and its ligands may contribute to the aggressiveness of human pancreatic cancer.
