Evaluation of EGD with Routine Screening Colonoscopy for the Early Detection of Stomach Cancer in High-Risk Groups, Pilot-SCREEN Trial

Trial Status: active

This clinical trial evaluates esophagogastroduodenoscopy (EGD) at the time of a routine screening colonoscopy for the early detection of stomach (gastric) cancer in high-risk groups. An EGD uses an endoscope, a lighted camera on the end of a tube, that is passed down the throat to visualize the upper part of the gastrointestinal tract (esophagus, stomach and duodenum) and remove tissue samples to be checked under a microscope for signs of disease. Screening EGD provides three distinct opportunities to decrease gastric cancer disease and death. First, it has potential to discover cancer in early stages before the onset of symptoms, leading to higher rates of survival. Second, pre-cancer lesions (changes that may develop into cancer) can be discovered and removed with local resection, preventing the development of cancer. Third, EGD discovery and treatment of active bacterial (helicobacter pylori) infection of the stomach provides an opportunity for primary prevention of gastric cancer. Adding EGD screening at the time of routine screening colonoscopy may be a safe and effective way to detect pre-cancers and cancers earlier in groups of people who are at high risk for gastric cancer.
