Overview

Helicobacter pylori (H. pylori) is a common bacterial infection which can lead to severe stomach problems or stomach cancer. Researchers will be looking at samples of the bacteria taken from chronically infected people in order to identify the genetic differences in H. pylori strains. The findings could help to predict which people with H. pylori will develop cancer, leading to earlier detection and prevention.

Study Information

Participants with H. pylori will have 6 small biopsies removed, each one approximately the size of a grain of rice. 

Participants with stomach cancer will donate some of the tissue that will be removed during their clinical care and will allow the study team to access the microscope slides of their stomach.

This is a multi-country, observational study of approximately 2000 people. It began on July 27th 2016 and is estimated to conclude on December 31st 2020.

Inclusion Criteria

1. Adult aged 35 to 70 years old.
2. Patients who need upper endoscopy (examination of the lining of their stomach with a flexible tube).
3. Patients recently diagnosed with stomach cancer.
