Aspirin after early stomach precancer or early cancer removal
Treatments studied
Part of Cancer, Digestive system clinical trials.
This trial tests whether taking aspirin after endoscopic removal of an early stomach condition can lower the chance of the cancer coming back or progressing. You may be considered if your early stomach findings were fully removed and you’re able to avoid certain medications that raise bleeding risk.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re age 19–70 and had an endoscopy to remove a high-grade stomach adenoma or early stomach cancer.
- Your pathology report after removal fits specific Japanese guideline criteria for “absolute” or “expanded” eligible cases.
- You either had a negative H. pylori test or you finished treatment to get rid of H. pylori (stomach bacteria).
- You have not been taking aspirin regularly (more than 3 times per week) in the 2 months before screening.
- You cannot use aspirin if you have reasons to avoid it, such as aspirin allergy or a bleeding-risk condition (for example, bleeding disorders, certain abnormal blood vessels, or active ulcers).
- You cannot be taking blood thinners or other antiplatelet medicines for medical treatment, and you’ve never had stomach surgery to remove part or all of it (gastrectomy).

Other trials that look related to this one.
This trial studies whether testing for an infection called H. pylori and using simple blood/screening tests (pepsinogen testing) can help prevent stomach cancer and reduce stomach-cancer-related deaths. You would be followed for health outcomes to see if the approach works better than standard care.
This study looks at people with certain stomach symptoms or precancer risk factors when they get a camera test of the upper digestive tract (endoscopy). The goal is to learn how to better detect and evaluate stomach precancer conditions early, which may help guide treatment or follow-up.
This trial tests whether taking aspirin (a common pain reliever and blood thinner) before and after surgery for pancreatic head cancer can improve outcomes. It may help reduce the chance of cancer returning or spreading.
This Phase 2 trial studies how aspirin affects specific “biomarkers” (measurable body signals) in people newly diagnosed with colon or rectal cancer. The goal is to see whether aspirin-related changes can help design more personalized prevention treatment plans.
This trial is testing whether taking a low dose of aspirin every day can lower the risk of developing liver cancer (hepatocellular carcinoma, or HCC) in people with liver cirrhosis. Liver cirrhosis is scarring of the liver, and having it increases the risk of liver cancer. If you are eligible, you would be asked to take aspirin or a placebo (a pill with no active medicine) and have regular check-ups to see if aspirin helps prevent cancer.
This trial tests if ursodeoxycholic acid can reverse intestinal metaplasia (a precancerous stomach condition) in patients who have no H. pylori infection. The goal is to see if this medication can help lower the risk of stomach cancer.
