Study stomach bacteria and stomach cancer in Martinique adults
This study looks at how common Helicobacter pylori (a common stomach germ) is in adults with stomach cancer in Martinique, and how it relates to stomach cancer. It mainly involves answering questionnaires and allowing study details to be collected to better understand risk and patterns.
Fort-de-FranceAges 18 years+ - NCT06509139Enrolling by invitationPhase 4
Finding the best treatment length for H. pylori infection
This study tests how long (10 or 14 days) a combination of four medicines (bismuth quadruple therapy) should be taken to best treat H. pylori infection, and whether the best duration differs between women and men. It aims to find the shortest effective treatment to reduce side effects.

Stomach cancer screening during routine colonoscopy
This study looks for early signs of stomach cancer and Barrett's esophagus (a precancerous condition) in people who are already getting a routine colonoscopy. By adding a quick upper endoscopy during the same visit, doctors can check for H. pylori infection and abnormal tissue changes without extra hassle.
ViennaAges 30 years+ - NCT07179159Recruiting

PoitiersAges Up to 16 years - NCT07724496Recruiting
H. pylori and stomach growth features study
This study looks at whether having H. pylori infection (a common stomach bacteria) and certain features of stomach growth can predict how early stomach cancer or pre-cancerous changes will behave and what your long-term outlook might be. You may be eligible if you are being treated with a camera-based removal procedure called endoscopic submucosal dissection (ESD).
