Evaluation of Stool Based Markers for the Early Detection of Colorectal Cancers and Adenomas
Forrás: ClinicalTrials.gov · Utoljára frissítve: 2026. máj. 11.
Rövid összefoglaló (regiszter, angolul)
Colon cancer is the second most common cancer in men and women. It is a disease that can be prevented if it is found early. Colonoscopy is still the best screening tool for colon cancer and the polyps that turn into colon cancer. However, due to a variety of factors, including affordability, time, and age, not all patients are able to be screened. Researchers are working on other options for early detection that are as accurate as colonoscopy. The purpose of this study if to determine if stool or blood can be used to detect colon cancers as early or earlier than colonoscopy. The researchers plan to use these samples to learn about specific proteins (also known as biomarkers) that may indicate colon polyps, colon cancer or an increased risk of developing colon cancer. In order to learn more about preventing and detecting colon and rectal cancer, we are collecting samples from subjects with cancer, adenomas, and colonoscopies who may be at risk for polyps.
