Background and study aims: The most important causes of hereditary colorectal cancer are Lynch syndrome (LS) and the adenomatous polyposis syndromes (familial adenomatous poly- posis syndrome or FAP, attenuated FAP or AFAP and MUTYH associated polyposis syndrome or MAP). The aim of this study was to investigate whether all patients with a hereditary syndrome within one center receive uniform advice regarding surveillance and treatment.

Patients and methods: A retrospective analysis was performed of all electronic patient health records of patients with LS, FAP, AFAP and MAP who received genetic counselling or were followed by a health care specialist at the University Hospital in Ghent.

Results: Data from 122 patients were collected. For all patients, recommendations from the medical genetics department were highly consistent. Adherence to their recommendations was good within the center for the management of colon polyps. There was a lack of consistency in the screening and surveillance advice for other tumors in departments other than gastroenterology. Only 33 patients had systematic follow-up consultations to check results and organize surveillance.

Conclusion: Previously, small studies have suggested that patients with hereditary gastrointestinal cancer syndromes infrequently have surveillance as specified in the guidelines. This study shows almost uniform recommendations and good adherence for surveillance of the colon, but incomplete or contradictory advice for surveillance of other organs. The need for an integrated approach from a multidisciplinary team will only increase in the future, because more families with hereditary cancer are likely to be found due to the increased use of next generation sequencing in cancer diagnostics.
