Abstract Objective To investigate the role of serum Helicobacter pylori (Hp) antibody combined with pepsinogen(PG) detection in the screening of gastric cancer and precancerous lesions. Methods A total of 440 cases of patients with gastric diseases in our hospital From June 2019 to January 2020 were selected as gastric disease group, and 112 cases of healthy people in our hospital were selected as control group. The Hp infections, serum PGⅠ, PGⅡlevels and PGR of the two groups were statistically analyzed. Results Comparison of Hp positive rates and HP negative rates between gastric disease groups (gastric cancer group, gastric ulcer group, atrophic gastritis group, superficial gastritis group) and healthy control group showed no statistically significant differences (P>0.05). The serum PGⅠlevel of patients in the gastric ulcer group was higher than that of healthy control group (P<0.05). The serum PGⅠlevel of gastric cancer group and atrophic gastritis group was lower than that of the healthy control group (P<0.05). The serum PGⅡlevel of gastric cancer group, gastric ulcer group and atrophic gastritis group was higher than that of healthy control group, while the PGR level was lower than that of healthy control group (P<0.05). There were no significant differences in serum PGⅠ, PGⅡlevels and PGR between the superficial gastritis group and the healthy control group (P>0.05).There were no statistically significant differences in serum PGⅠ, PGⅡlevels and PGR between Hp positive and Hp negative subjects in gastric cancer group, gastric ulcer group, atrophic gastritis group, superficial gastritis group and healthy control group (P>0.05). Conclusion In the screening of gastric cancer and precancerous lesions, the detection of Hp antibody and PG has positive clinical diagnostic value and is worthy of promotion.
