Capsule test during endoscopy to find early esophageal cancer

This trial tests a small sponge-on-a-string device (called a capsule sponge) that is swallowed to help detect esophageal cancer early. It may be a gentler way to check the food pipe for cancer than a standard endoscopy, and is being studied in people with esophageal cancer, those at high risk, and healthy volunteers.

This study checks whether a swallowable capsule can help find signs of Barrett’s esophagus or esophageal cancer (or related risk) before or around an endoscopy. The goal is to see if this less invasive sampling method could improve screening.

This study checks whether a special swallowable “camera capsule” test done in primary care can find early warning changes called Barrett’s esophagus. If it works well, it could make screening easier for people at risk.

This trial tests a device that collects cells from the esophagus using a swallowed capsule, which may detect Barrett's esophagus without a standard endoscopy. It is for people who are already scheduled for an endoscopy.

This study tests less invasive ways to detect high-grade dysplasia (very abnormal cells) and esophageal cancer in people with Barrett's esophagus, a condition that can increase cancer risk. It looks for these changes using cell samples taken during a routine endoscopy, which may be quicker and more comfortable than standard biopsies.

This study tests a less invasive way to check for Barrett's esophagus and esophageal cancer. Instead of a standard endoscopy, they may use a sponge-on-a-string or other simpler methods, which could be more comfortable and easier for patients.
