A simple test could spot who will develop stomach cancer
NCT ID NCT05782465
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This study is testing whether a customized molecular test can identify which people with intestinal metaplasia—a condition that can precede stomach cancer—are at very high risk of developing the disease. Researchers will collect blood and stomach tissue samples from 500 adults aged 50 to 75 and follow them over several years to see if the test's predictions hold true. If it works, the test could help doctors focus surveillance on those who need it most and avoid unnecessary procedures for others.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A molecular test using blood and stomach biopsy samples to assess stomach cancer risk
- What this could lead to
- If successful, this test could help doctors focus stomach cancer surveillance on those at highest risk, while reducing unnecessary procedures for others.
- What could go wrong
- The test is still being validated, and it may not accurately predict risk in all patients. It is not yet a proven tool for routine use.

Inclusion Criteria: 1. The subject is above 50 years old or turns 50 years old in the year of recruitment 2. The subject is below 76 years old in the year of recruitment 3. The subject is willing and able to provide signed and dated patient informed consent form indicating that they has been informed of all pertinent aspects of the study Exclusion Criteria: 1. The subject who has bleeding disorders, such as haemophilia, in whom biopsies are contraindicated. 2. The subject with a personal history of high-grade dysplasia or GC. 3. The subject with liver cirrhosis. 4. The subject with previous total or partial gastrectomy. 5. The subject with severe co-morbid illness, such as end-stage renal failure (ESRF), congestive cardiac failure (CCF), severe osteoarthritis (OA), and rheumatoid arthritis (RA) requiring long-term non-steroidal anti-inflammatory drug (NSAID) therapy. 6. The subject with other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may interfere with the interpretation of study results and in the judgement of the investigator would make the subject unsuitable for entry into the study. 7. The subject on regular anti-coagulant prophylaxis such as warfarin must be able to undergo a 5-day washout period before each gastroscopy. The subject on aspirin, ticlopidine and clopidogrel must be able to undergo a one-week washout period before each gastroscopy. The subject's physician or study co-investigator will exercise their clinical judgement to ensure subject's safety. 8. The subject is unwilling or unable to provide signed informed consent.
