Polyprev: Study to Compare Fecal Immunochemical Test With Endoscopic Surveillance After Advanced Adenoma Resection in Fecal Immunochemical Test Colorectal Cancer Screening Programs.
Sponsor: Fundacin Biomedica Galicia Sur
Summary
Colorectal cancer (CRC) screening programs have been implemented to reduce the burden of the disease. When an advanced colonic lesions is detected, it is recommended to perform endoscopic surveillance with different intervals between explorations. Although the reduction in CRC incidence, endoscopic surveillance is producing a considerable increase in the number of colonoscopies. However, participation in CRC screening programs based on the fecal immunochemical test (FIT) could be a non inferior alternative to endoscopic surveillance. Based on this hypothesis, the research group have designed a randomized clinical trial within the population CRC screening programs to compare FIT surveillance to endoscopic surveillance in patients with advanced lesions resected.

Annual FIT
Patients will be offered an annual FIT and colonoscopy will be performed if fecal hemoglobin concentration is ≥10µg / g of feces. After performing a colonoscopy the FIT will be sent to the patient: * After one year if the unscheduled colonoscopy has been incomplete or a lesion requiring endoscopic surveillance has been completely resected. * After five years if the colonoscopy has evaluated the entire mucosa, it is normal or with lesions that do not require endoscopic surveillance (1-2 non-advanced adenomas).
Endoscopic surveillance.
First surveillance colonoscopy will be performed in three-year time. If an advanced adenoma or at least three non-advanced adenomas are detected, colonoscopy will be repeated after 3 years. In contrast, if colonoscopy is normal or 1-2 non-advanced adenomas are detected, colonoscopy will be repeated after 5 years.
