Helicobacter pylori is a common bacterial infection. It can lead to severe stomach problems or stomach cancer. Researchers want to look at samples of the bacteria. These will be taken from chronically infected people. They want to identify the genetic differences in H. pylori strains. This could help predict which people who get infected with the bacteria will get cancer. This could lead to the cancer being detected earlier. It could also mean less people get stomach cancer.
To study genetic variations of H. pylori strains based on samples from chronically infected people. To identify the features of strains that might lead to severe stomach problems or stomach cancer.
People ages 35 70 who need an upper endoscopy or who were recently diagnosed with stomach cancer
Participants will be screened by the doctor who does their procedure and a study nurse.
Participants who have endoscopy will have 6 biopsies removed. These are tissue samples. They are about the size of a grain of rice. Participants will allow the study team to access reports from their stomach exam.
Participants with stomach cancer will donate some of the tissue that will be removed during their clinical care. They will allow the study team to access reports of their surgery. They will also allow them to access the microscope slides of their stomach.
