RESUMEN

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.

RESUMEN

Objective: To study the relationship of expression of CDX2 and PTEN proteins and gastric metaplasia. Methods: Immunohistochemistry Envision method was used to detect the expression of CDX2 and PTEN proteins in simple intestinal metaplasia (SIM), atypical intestinal metaplasia (AIM) and gastric adenocarcinoma. Results: The positive rates of CDX2 in SIM, AIM and gastric adenocarcinoma was 82.6%, 51.5% and 36.4% respectively. The expression of CDX2 in gastric adenocarcinoma was significantly lower than that in SIM(P0.05). The positive rates of PTEN in SIM, AIM and gastric adenocarcinoma were 86.9%,75.8%and 47.7% respectively and the difference between SIM and gastric adenocarcinoma was significant (P
