Researchers are studying a special type of DNA called extracellular DNA (ecDNA) that appears in cancer cells but not in healthy cells. This trial will collect tissue samples from 1,000 people—some with stomach precancers, some with normal stomach tissue, and some with stomach cancer—to understand how this abnormal DNA may cause stomach cancer to develop. By tracking changes in this DNA over time, doctors hope to predict who might develop stomach cancer and improve treatment.
Most people with stomach cancer are diagnosed at advanced stages when treatment is harder. Researchers believe that studying this abnormal DNA could help identify people at risk for developing stomach cancer earlier, when it may be easier to treat and prevent.

You likely don't qualify if…
If you qualify, your doctor will take a small tissue sample during a routine stomach scope or surgical procedure. You'll need to agree that researchers can study your tissue sample and compare it with samples from others to track how the abnormal DNA changes over time. This is an observational study, meaning researchers will follow your samples and health information over time rather than giving you a new medication to test.
