BackgroundScreening of colorectal cancer (CRC) can reduce incidence and mortality. First-degree relatives (FDRs) of patients with CRC or advanced adenoma before the age of 65 (index patients) are at increased risk of CRC; however, the guidelines for screening of FDRs by colonoscopy are poorly followed.ObjectivesThe present study, conducted in the context of the COLOR3 interventional study project, aimed to explore the positioning of general practitioners (GPs) in familial CRC screening in France.MethodsFrom February 2020 to April 2021, 35 semi-structured interviews with GPs of index patients and/or their FDRs were conducted by telephone. The full-data transcribed corpus was subjected to horizontal thematic analysis.ResultsKnowledge and compliance with the guidelines vary greatly between GPs. Although initiating the diagnostic process, GPs do not consider themselves as actors in the flow of information concerning familial risk. Their accompaniment of index patients in this role varies. GPs should overcome barriers to implementing colonoscopic screening for FDRs. They underline the importance of exploring family history, but they lack the time and doubt the reliability of the information given by FDRs.ConclusionChallenges include circumventing gaps in knowledge, adherence to guidelines and improving family history updates. The GPs interviewed suggested personalised guidelines in specialists' reports to initiate information campaigns raising awareness of familial risk, and to enhance coordination between organised screening and familial screening.
