The Correlation Between Cytoplasmic Overexpression of Epidermal Growth Factor Receptor and Tumor Aggressiveness

Abstract

It is suggested that the cytoplasmic overexpression of EGFr plays a significant role in the progression of pancreatic ductal adenocarcinoma, especially in the invasion and acquisition of aggressive clinical behavior. Both membrane and cytoplasmic expression of HER-2 showed no significant correlation between tumor differentiation and poor survival.
