ABSTRACT

Objective:To study the expressions of c-erbB-2 and ki67 proteins in simple intestinal metaplasia(SIM),atypical intestinal metaplasia(AIM) and gastric adenocarcinoma,and the relationships among them.Methods:The immunohistochemical EnVision method was used to determine the expressions of c-erbB-2 and ki67 in 27 cases of SIM,26 cases of AIM and 37 cases of gastric adenocarcinoma.Results:The positive rates of c-erbB-2 and ki67 in gastric adenocarcinoma were significantly higher than that in SIM(P0.05).Conclusion:The high expression of c-erbB-2 and ki67 in AIM and gastric adenocarcinoma suggested that AIM may play an important role in gastric adenocarcinoma.The AIM is one kind of precancerosis of gastric adenocarcinoma.
