Check gastric cancer using breath chemical signals

Gastric CancerAtrophic GastritisGastric DysplasiaH.Pylori Infection

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.

Phase
N/A
Enrollment
5,000 people
Ages
18 years and older
Study type
Observational

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.

Breath and blood test for gastro-esophageal cancer and Barrett's esophagus

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.

Breath and blood tests to study stomach and food-pipe cancer

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.

Metabolic biomarkers for stomach cancer detection and monitoring

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.

Study blood, tumor tissue, and preferences to predict stomach cancer response

This study looks at stomach (or stomach–esophagus junction) cancer tissue, treatment details, and patient-reported experiences to better predict how you may respond to standard chemotherapy. It may help personalize future treatment by identifying markers that connect your tumor environment and your expected outcomes.

Stomach bacteria study for gastric conditions and precancer

This study looks for certain stomach bacteria (other than the common H. pylori) that might be linked to stomach diseases or early signs of cancer. If you have a stomach condition, your participation could help doctors understand these bacteria better.
