EFFECTIVENESS OF EARLY INFORMATION AND ENDORSMENT BY GP TO INCREASE COLONOSCOPY FOLLOW-UP AND REDUCE DELAYS IN PEOPLE WITH A POSITIVE COLORECTAL CANCER SCREENING TEST. (SUIVICOLO)

France2,000 participantsStarted 2026-03-24

Plain-language summary

To be effective, organized colorectal cancer screening requires good adherence to diagnostic colonoscopy in the event of a positive test. In France, the rate of diagnostic colonoscopy following a positive colorectal cancer screening test is less than 85%, and the median delay is close to 90 days. After receiving their positive result from the laboratory, individuals with no known follow-up are contacted only six months later by the Regional Cancer Screening Coordination Centers (CRCDC) responsible for following up with individuals who have tested positive. To optimize follow-up with colonoscopy, earlier contact and information about colonoscopy appear to be necessary. The contribution of the general practitioner identified on the test could be an additional lever. The SUIVICOLO study aims to evaluate the effectiveness on the rate of colonoscopies performed at 6 months of two strategies for optimizing the follow-up of positive results in comparison with control group C (current procedures of the CRCDC Centre Val de Loire without early letter). The two strategies evaluated will be: * Group B1: Sending an early letter signed by the CRCDC accompanied by information leaflet about colonoscopy * Group B2: Sending an early letter co-signed by the CRCDC and the general practitioner (identified or provided by the patient on the test identification form) accompanied by information leaflet about colonoscopy. These strategies will be compared to the current follow-up strategy in a three arm randomized controlled arm.

Inclusion Criteria: * Aged between 50 and 75 at the time of the positive colorectal cancer screening test * Residing in one of the departments of the Centre Val de Loire region * Date on which the positive CRC screening test result was sent to the beneficiary recorded * Colorectal cancer screening test results sent to the beneficiary within 30 days of the test being read * Affiliated with a health insurance fund Exclusion Criteria: * Subjects who have notified their refusal to allow their data to be used for research purposes will be excluded from the analyses.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
