Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Comparaison of neoplastic colon polyp number detected between CTC and colonoscopy
Number of detection of neoplastic colon polyp
Secondary outcome measures
Number of patients on the list having a CTC and diagnosed with advanced neoplasia, non-advanced CR neoplasia, CR cancerous and precancerous lesions on colonoscopy

Trial Design

3Treatment groups
Active Control
Group I: a colonoscopy as surveillance examActive Control1 Intervention
patients will undergo Colonoscopy, finding will be documented. Findings of colonoscopy will be documented and treated according to the institutional standards. Study participation for patients ends after the colonoscopy and follow-up of pathology results and complication assessment.
Group II: undergoing CT colonography as surveillance examActive Control1 Intervention
If CTC is positive: patients will have subsequent colonoscopy within 3 months. Findings will be documented and participation in the study will end there. Findings of the colonoscopy will be addressed according to our institution's guidelines. If CTC is negative for polypoid lesions patient will leave the study and will have a follow up 5 years after with either a CTC or colonoscopy.
Group III: undergoing a FIT as surveillance examActive Control1 Intervention
if the FIT test is positive: patients will have subsequent colonoscopy within 3 months. Findings of FIT testing and if positive the colonoscopy will be documented and participation in the study will end after that. Findings of the FIT test and colonoscopy will be treated according to the institutional standards. If FIT test is negative patient will leave the study and will have a follow up with a colonoscopy or FIT test in 1 to 2 years outside of this study.
