Relationship of expression of CDX2 and PTEN proteins and gastric metaplasia / 中国现代普通外科进展

ABSTRACT

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
