Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older who have a confirmed diagnosis of FAP and have undergone prophylactic (procto)colectomy.

Probably not a fit

Patients who have active cancer at baseline endoscopy or those unable to have polyps removed during endoscopic procedures may not benefit from this study.

What this trial studies

This study aims to evaluate the effectiveness and safety of a personalized surveillance and intervention protocol for patients diagnosed with familial adenomatous polyposis (FAP) who have undergone prophylactic (procto)colectomy. FAP is a genetic condition that leads to the development of numerous polyps in the colon and rectum, significantly increasing the risk of colorectal cancer. The study will monitor patients post-surgery to manage and prevent the progression of adenomas and potential cancer development through tailored endoscopic surveillance and interventions. Participants will be followed over time to assess the outcomes of this personalized approach.

Why it matters

Potential benefit: If successful, this protocol could significantly reduce the risk of colorectal cancer in patients with FAP by providing tailored surveillance and intervention strategies.

How similar studies have gone: While personalized surveillance approaches have been explored in other contexts, this specific protocol for FAP post-surgery is novel and has not been extensively tested.
