Abstract:
The aim of this study was to evaluate, by means of an immunoenzymatic assay, the membranous and cytosolic c-erbB-2 oncoprotein contents in primary tumors and in adjacent mucosa from gastric cancer patients. Fifty-two patients with primary gastric adenocarcinomas were enrolled in this prospective study. c-erbB-2 protein levels were significantly higher in membranous than in cytosolic samples, both in neoplastic tissues (median: 3602 vs 525 NHU/mg protein; p<0.0001) and in adjacent mucosa samples (median: 3174 vs 509 NHU/mg protein; p<0.0001). Nevertheless, there was a significant positive relation between membranous and cytosolic c-erbB-2 protein contents in both neoplastic tissue (p<0.001) and adjacent mucosa (p<0.001) samples. There was no significant difference in the membranous c-erbB-2 protein content between neoplastic tissues and adjacent mucosa samples. However, the cytosolic c-erbB-2 content was significantly higher in neoplastic tissues than in adjacent mucosa (p<0.05). Finally, the results did not show any significant correlations of these oncoprotein contents with patient characteristics, clinicopathologic parameters and overall survival of the study population.
