Association study of Uygur esophageal squamous cell carcinoma in Hp infected patients with cancer cell proliferation and invasion / 中国免疫学杂志

ABSTRACT

Objective:To investigate the relationship between helicobacter pylori ( Hp) infection and proliferation as well as invasion of Uygur esophagus squamous cell carcinoma.Methods: Immunohistochemistry were used to detect Hp , Ki67 and MMP2 protein in 164 cases of Xinjiang Uygur esophageal squamous cell carcinoma tissue specimens.Results: The positive rates of Hp,Ki67 and MMP2 were 81.7%(134/164),67.1%(110/54) and 86.6%(142/164) respectively in 164 cases of esophageal squamous cell carcinoma.The expression of Ki67 in the Hp positive group of patients with esophageal squamous cell carcinoma were significantly higher than that in the Hp negative group and had positive correlation between them (rs=0.340,P<0.01),the expression of MMP2 in the Hp positive group were significantly higher than that in the Hp negative group and had positive correlation between them ( rs=0.739,P<0.01).Conclusion:The relationship between Xinjiang Uygur esophageal squamous cell carcinoma patients with Hp infection and cancer cell malignant degree of proliferation and invasion is close.
