Risk Assessment Evaluation for Identifying Participants at High Risk for Stomach Cancer

Study Summary

This clinical trial evaluates the usefulness of various risk assessment tests, including Helicobacter pylori (H. pylori) breath testing, questionnaires, and endoscopies for identifying participants at high risk for stomach cancer. H. pylori is a bacteria that causes stomach inflammation and ulcers in the stomach. People with H. pylori infections may be more likely to develop cancer in the stomach. H. pylori breath testing can help identify the presence of H. pylori infection in a participant and help identify if the participant may be at a higher risk of developing stomach cancer. An endoscopy uses a thin, flexible lighted tube that is inserted inside the esophagus, stomach, and first part of the small intestine. This allows the doctor to see and look for abnormal areas that may need to be biopsied. Risk assessment including H. pylori evaluation, questionnaires, and endoscopies may help identify participants at high risk for stomach cancer and may be a useful screening tool for earlier stomach cancer diagnosis.

Primary Outcome

Study feasibility will be defined as ≥ 10% of screened individuals found to be at high risk for gastric cancer. The study will be successful if ≥ 10% of screened individuals (24 of ≤ 240) have a risk score of ≥ 12 or have signs/symptoms that have persisted for ≥ 1 month that are associated with gastric cancer. The reported results will include counts/proportions of screened individuals found to be at high risk for gastric cancer (≥ 12 risk score).
