  1. Negative genetic test result in familial adenomatous polyposis : Clinical screening implications. Invited editorial.

    Article, Communication - En anglais

    Meeting of The American Society of Colon and Rectal Surgeons. San Antonio, TX, USA, 1998/05/02.

    PURPOSE 

    The goal of genetic testing is to define individual risk, which in turn may guide clinical management.

    METHODS 

    Thirty-two international familial adenomatous polyposis registries were surveyed regarding their approach to a specific clinical management question.

    There were 30 respondents.

    Respondents declared their clinical policy for an at-risk, first-degree relative who undergoes direct mutation analysis and does not have an APC gene mutation known to be present in his or her family.

    RESULTS 

    Nineteen of 30 (63.3 percent) registries would discharge this negative APC mutation case from clinical screening.

    Eleven of 30 (37 percent) registries would maintain clinical screening.

    Reasons offered for maintaining surveillance included the need for additional confirmation of the APC mutation in two affected relatives, the possibility of sampling error or two different mutations in an affected family, limited prospective data, and patient anxiety.

    CONCLUSIONS 

    The discrepancy in response to the survey suggests that some clinicians are as yet reluctant to accept fully that predictive genetic analysis is a definitive guide to clinical management in familial adenomatous polyposis.

    Nevertheless, we believe that use of a predictive gene test for familial adenomatous polyposis should alter management, decrease cost, and reduce psychological trauma for the tested individual. (...)
