c-erbB-2 Is of Independent Prognostic Relevance in Gastric Cancer and Is Associated With the Expression of Tumor-Associated Protease Systems

Abstract

c-erbB-2 is confirmed as a new independent, functional prognostic parameter for overall survival in gastric cancer, even when a panel of invasion-related factors, including the strong prognostic parameter PAI-1, are considered. The significant correlation of p185 with several tumor-associated proteases supports the hypothesis that c-erbB-2 is a promoter of invasion and metastasis. This strongly suggests that c-erbB-2 may be a promising target for anti-invasive therapy in gastric cancer.
