Официальное название
Randomized Controlled Trial Evaluating the Efficacy of CAD in Screening Colonoscopy to Reduce the Risk of Advanced Adenoma at 3 Years.
Обзор
The occurrence of interval cancers after colonoscopy raises the possibility of missed lesions. High- performance computer aided diagnosis (CAD) systems have been specially designed for the detection of colorectal lesions (CAD for detection is named CADe). The use of CADe improves adenoma detection in screening colonoscopy. The potential of CADe system in reducing the rate of progression to advanced polyps or interval cancer between two colonoscopies remains still uncertain.
Подробное описание
Patients will be enrolled after a pre-colonoscopy consultation and risk-assessment for colorectal cancer. The screening colonoscopy will be performed by an investigator. Patients will be randomized in the endoscopy room after confirmed cecal intubation and quality of bowel preparation. Randomization into two groups: standard colonoscopy vs. colonoscopy with CADe (CAD EYE or GENIUS) (1:1). A follow-up consultation will be scheduled one-month postcolonoscopy for delivery of histological results and then at 3 years in order to organize the next colonoscopy. As part of the study, a new control colonoscopy will be scheduled for patients with high risk of CRC at 3 years. The 3-year control colonoscopy will be performed with the CAD system for all patients. The colonoscopy will be performed by another investigator who does not know the results nor the type of the first colonoscopy (evaluator blinded). In the low-risk group, we will collect follow-up data as part of routine care, including the results of colonoscopies performed outside of the protocol
