Relationship between RUNX3 expression and precancerous gastric lesions in high-risk population / 北京大学学报(医学版)

ABSTRACT

Objective:To evaluate the association between RUNX3 expression and Helicobacter pylori(H.pylori)-associated precancerous gastric lesions.Methods: A population-based study was conducted in Linqu County,Shandong Province,a high-risk area of gastric cancer in China.RUNX3 expression was determined by immunohistochemistry analysis in 1 026 H.pylori infected subjects with different gastric lesions.Results: Among 1 026 subjects,359(35.0%,359/1 026) was positive.The prevalence rates of RUNX3 expression decreased steadily with severity of gastric lesions,65.6%(40/61) among those with superficial gastritis /normal(SG/N),and 22.4%(60/268) among those with dysplasia(DYS)(P
