Check gastric cancer using breath chemical signals
Part of Cancer, Digestive system clinical trials.
This study looks at chemical signals in your breath to help screen for or understand gastric (stomach) cancer. It may help doctors improve earlier detection, or better sort out who may need further tests.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have verified gastric (stomach) cancer, or you fit one of the study comparison groups described by the study (including certain people having endoscopy or an average-risk group).
- If you’re in the “endoscopy” groups: you’re currently scheduled for, or have already had, an upper endoscopy for a medical reason.
- If you’re in the average-risk group: you’re aged 40 to 64 and you do not have “alarm symptoms” (concerning warning signs) at the time of enrollment.
- You are willing and able to participate, including giving breath samples and doing the other study steps.
- You can physically do the breath sampling and related procedures, and you can sign the consent form.

This study is testing whether a simple breath and blood test can help doctors better understand gastro-esophageal cancer and Barrett's esophagus. It aims to see if these non-invasive samples can provide useful information for diagnosis and monitoring.
This study looks at how certain “volatile” substances in breath change in people with stomach or food-pipe (oesophageal) cancer, compared with people who have other non-cancer stomach/food-pipe conditions. It may help researchers find better, earlier ways to assess cancer—especially in people who have not started treatment yet.
This study looks for metabolic markers in your blood and tumor tissue to help find stomach cancer early, predict your prognosis, and watch for recurrence. If you qualify, you would give blood and tumor samples for testing.
This study looks for markers in the blood that could show if someone is at risk for stomach cancer or pre-cancerous changes. It aims to help catch problems earlier.
This study collects breath samples from women with suspicious breast ultrasound findings (BI-RADS 4) before surgery to see if certain chemicals in the breath can help identify cancer. If you are scheduled for surgery soon, your breath may help researchers find a new way to screen for breast cancer.
This study tests whether a simple breath test can help detect different types of gastrointestinal cancers earlier. If you have been recently diagnosed with one of these cancers or have concerning abdominal symptoms but clear test results, your breath may help teach us how to spot these cancers sooner.
