Early gastric cancer

This study looks at whether adding sucralfate (a protective coating agent) to standard esomeprazole (a stomach acid reducer) helps heal artificial ulcers created during endoscopic surgery for early stomach cancer or precancerous growths. About 120 adults will be randomly assigned…

This study compares two types of minimally invasive surgery for early-stage stomach cancer: a newer robotic method using fewer incisions (reduced-port) and the standard laparoscopic method. About 538 patients will be randomly assigned to one of the two surgeries. The main goal is…

This study tests a less invasive surgical approach for people with early gastric cancer who need additional treatment after an initial endoscopic removal. The procedure uses a special dye to guide removal of nearby lymph nodes, with or without removing a small part of the stomach…

This study looks at whether a special microscope on a thin probe (pCLE) can better detect early stomach cancer than the usual biopsy method. Researchers will review past cases from 169 patients who had both tests. The goal is to see which method is more sensitive and accurate, wh…

This study will develop and test a diagnostic model to help doctors identify early gastric cancer during endoscopy. Researchers will use a special imaging technique called narrow band imaging (NBI) to examine suspicious lesions in 300 patients aged 40-80. The goal is to improve a…

This study tests whether a special imaging mode called RDI helps doctors remove early-stage cancers from the stomach, esophagus, or colon more quickly and safely than standard white-light endoscopy. About 158 adults with early cancers or precancerous lesions will be randomly assi…

This study looks at how often polyps in the stomach or colon grow back after being removed during a scope procedure. Researchers will follow about 2,000 adults for up to three years to track recurrence and identify risk factors like polyp size, lifestyle, and health history. The …
