Clinical Trial Summary

This study evaluate whether treatment of Helicobacter pylori infection reduces the incidence of gastric cancer in subjects with family history of gastric cancer.

Description:

Helicobacter pylori infection is associated with gastric cancer in epidemiological studies. However, it is still unknown whether H. pylori eradication is useful and required to prevent gastric cancer.

Gastric cancer risk is increased in family members of gastric cancer patient. Though there is no direct evidence that H. pylori infection is a risk factor for gastric cancer in family members of gastric cancer, current European guideline recommends H. pylori eradication in first-degree relatives of gastric cancer patients.

In this study, the investigators will evaluate whether H. pylori eradication can reduce gastric cancer risk in the first-degree family members of gastric cancer patients.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Gastric cancer incidence	The incidence of gastric cancer will be compared between the two arms as the participant assigned into either LAC treatment group or placebo group regardless the final H. pylori infection status.; Currently, efficacy of LAC triple therapy shows about 75-85% eradication rate of the H. pylori.	6 years after last participant enrollment
Secondary	Gastric dysplasia incidence	Incidence of gastric dysplasia according to the H. pylori treatment	6 year after last participant enrollment
Secondary	Gastric cancer incidence between H. pylori treatment and H. pylori uninfected groups	Gastric cancer incidence between H. pylori treatment group and H. pylori uninfected group	6 year after last participant enrollment
Secondary	Gastric cancer incidence according to H. pylori status	Gastric cancer incidence between H. pylori eradicated group and H. pylori persistent group	6 year after last participant enrollment
Secondary	All-cause mortality	All-cause mortality between H. pylori treatment group and placebo group	6 year after last participant enrollment
