COLORECTAL ADENOMA

This study looks at whether a non-invasive stool test (qFIT) can accurately detect colorectal cancer and precancerous lesions in adults aged 40–75 who are already scheduled for a colonoscopy. Researchers will compare the test results with colonoscopy findings to see how well qFIT…

This study aims to improve how we screen for colorectal cancer by using a new blood test. Researchers will look for special molecules called oncofetal chondroitin sulfate (ofCS) that appear in tumors. They will collect blood from 2000 people scheduled for a colonoscopy to see if …

This study tests whether taking a probiotic called Clostridium butyricum can prevent colorectal adenomas (precancerous polyps) from returning after they are removed during a colonoscopy. About 294 adults who have had polyps removed will take either the probiotic or a placebo dail…

This study tests whether eating more plants and less animal food can lower colorectal cancer risk. Forty adults who have had colon polyps removed will follow a diet education program. Researchers will measure changes in gut bacteria and bile acids linked to cancer.

This study tests whether a traditional Chinese herbal medicine, Jianpi Lishi Jiedu Granules, can prevent colon polyps from returning after they are removed. About 376 adults who had advanced polyps removed will take either the herbal granules or a placebo for 3 months. Researcher…

This study will develop and test an artificial intelligence system that uses video from colonoscopies to assess how clean the bowel is. The goal is to make the assessment more reliable by accounting for the speed at which the scope is withdrawn. The study involves 700 participant…

This study looks at tiny chemical changes in the DNA of colon polyps (precancerous growths) to find better ways to detect colon cancer early. Researchers will collect polyp and normal tissue samples from 32 Korean adults during a routine colonoscopy. They will also analyze stool …

This study will follow about 2,000 adults who had polyps removed from their stomach or colon to see how often the polyps grow back. Researchers will look at factors like polyp size, lifestyle, and medical history to create a risk score. The goal is to help doctors personalize fol…

This study tests whether adding a clear plastic cap to the tip of a colonoscope helps doctors find more polyps (adenomas) in the lower part of the colon during a second look. About 614 adults aged 45 to 75 will take part. The goal is to see if this simple tool improves detection …
