OBJECTIVE: In order to analyse the association between Hp infection and the risk of upper-digestive tract cancer.
METHODS: In Huaian and Pizhou cities, Jiangsu province, Hp IgG quantitative-enzyme-immunoassay methods was used to identify IgG to H.pylori in the serum of 312 cases of upper-digestive tract cancer patients and their kindreds.
RESULTS: (1) The level of IgG to H. pylori and the IgG positive rate (50.0%) in gastric cancer patients were both higher than that of cardia and esophageal cancer patients (P > 0.05, chi 2 test) but no significant differences were observed between cardia and esophageal cancer patients, 3 types of cancer patients and their kindreds; (2) the overall positive rates of both patients and kindreds in gastric cancer families (27.1%) were significantly higher than that of cardia or esophageal cancer families (P < 0.05) but no significant differences were observed between cardia and esophageal groups.
CONCLUSION: H.pylori infection was not thought to be correlated with the development of gastric cancer, although higher clustering of Hp infection in families afflicted with gastric cancer was noticed.
