METHODS： In total, 199 oral squamous-cell carcinoma （SCC）, 317 esophagea! SCC, 196 gastric cardia and non-cardia adenocarcinoma and 240 colon adenocarcinoma patients were recruited for serum tests of Hpylori infection. Two hospital- and one community-based control groups were used for the comparisons. Hpylori seropositivity was determined by an enzyme linked immunosorbent assay method against Hpylori IgG. RESULTS： Presence of H pylori infection was significantly inversely associated with esophageal SCC [adjusted odds ratio （AOR）： 0.315-0.472, all P-value 〈 0.05] but positively associated with gastric adenocarcinoma （both cardia and non-cardia） （AOR： 1.636-3.060, all P-value 〈 0.05） in comparison to the three control groups. Similar results were not found in cancers of the oral cavity and colon. CONCLUSION： Our findings support the finding that H pylori seropositivity is inversely associated with esophageal SCC risk, but increases the risk of gastric cardia adenocarcinoma.展开更多

METHODS:The population of patients consisted of subjects in whom H pylori infection had been successfully treated in the past.Patients were divided into two groups:Ⅰ-examined group(111 persons with H pylori re-infection)andⅡ-control group(175 persons who had not been re-infected).The respondents were interviewed retrospectively on their dietary habits and socio-economic factors. RESULTS:A statistically significant lower frequency of fermented dairy products(P<0.0001),vegetables (P=0.02),and fruit(P=0.008)consumption was noted among patients with H pylori re-infection as compared to those who had not been re-infected. CONCLUSION:High dietary intake of probiotic bacteria,mainly Lactobacillus,and antioxidants,mainly vitamin C(contained in fruit and vegetables),might decrease the risk of H pylori re-infection.展开更多
