Conditions gastric cancer, bacterial infection due to helicobacter pylori (h. pylori)
Treatments placebo, lac triple therapy
Phase phase 3
Sponsor National Cancer Center, Korea
Start date November 2004
End date February 2018
Trial size 1810 participants
Trial identifier NCT01678027, NCCSTS04-103


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.
