Objective To explore changes of serum levels of tumor necrosis factor alpha(TNF-α),interleukin-10(IL-10),and Helicobacter pylori(HP)positivity rate in patients with early gastric cancer,and the diagnostic value of three factors in early gastric cancer.Methods A total of 312 patients with gastric discomfort were included in this study and used as the observation subjects.Patients were divided into the gastritis group(n=100),the precancerous lesion group(n=110)and the early gastric cancer group(n=102)based on their gastroscopy.Enzyme linked immunosorbent assay(ELISA)was used to detect serum levels of TNF-α and IL-10.HP infection was detected in the three groups.Multivariate Logistic regression was used to analyze influencing factors of early gastric cancer.Receiver operating characteristic(ROC)curve analysis was used to evaluate the diagnostic value of serum TNF-α,IL-10 and HP infection in early gastric cancer.Results The levels of TNF-α,IL-10 and HP positivity rate were increased in the gastritis group,the precancerous lesion group and the early gastric cancer group in sequence(all P＜0.05).Hot food,heavy salt,pepsinogen Ⅱ(PG Ⅱ),HP positivity and elevated levels of TNF-α and IL-10 were independent risk factors for early gastric cancer,while elevated PGⅠ was a protective factor(all P＜0.05).The areas under the curve for serum TNF-α,IL-10,HP infection and their combined diagnosis of early gastric cancer were 0.694,0.698,0.763,and 0.870,respectively.The combined diagnostic efficacy of the three was better than that of individual diagnosis(all P＜0.05).Conclusion The serum levels of TNF-α,IL-10 and HP positivity rate are significantly increased in patients with early gastric cancer,and all three have certain diagnostic value for early gastric cancer.
