Changes of serum IL-6 and IL-8 levels in patients with gastric cancer and the clinical relationships with Helicobacter pylori infection / 中国医师杂志

ABSTRACT

Objective To explore the changes of serum interleukin-6 (IL-6),and interleukin-8 (IL-8) in patients with gastric cancers and the clinical relationships with Helicobacter pylori (Hp) infection.Methods Totally 62 cases of patients who were diagnosed gastric cancer in our hospital from January 2013 to September 2015 were selected as the study group,who did not accept anti-tumor therapy.The patients were divided into the Hp positive group (with 53 cases) and Hp negative group (with 9 cases) according to whether the merger of Hp infection.Another 60 normal healthy volunteers of the same age in our hospital for health examination during the same period were selected as the control group.The serum IL-6 and IL-8 levels were detected,and the changes of the factors in the study group and control group were compared and analyzed,as well as the U values of Hp infection.The clinical relationships between the expression levels of the two in patients with gastric cancer and the U values of Hp infection were confirmed.Results The serum IL-6 and IL-8 levels and the U values of Hp infection of the study group were significantly higher than those of the control group (P ＜ 0.05),which in the Hp positive group were significantly higher than those in the Hp negative group (P ＜ 0.05).The levels of serum IL-6 and IL-8 in patients with gastric cancer showed positive correlations with the U value of Hp infection (r =0.457,0.531,P ＜ 0.05).Conclusions The serum IL-6 and IL-8 levels in patients with gastric cancer are much higher than those in normal healthy people,and there are significant positive relationship with Hp infection.It can improve the curative effect of gastric cancer patients by improving the eradication rate of Hp.
