Colorectal cancer surveillance behaviors among members of typical and attenuated FAP families.

Objectives: Although enhanced colorectal surveillance is recommended for members of familial adenomatous polyposis (FAP) families, little is known about individual-level adherence behavior. This study examined factors associated with recent use of colorectal cancer (CRC) surveillance among FAP patients and their at-risk relatives.

Methods: This cross-sectional study conducted a computer-assisted telephone survey among 150 members of 71 extended families with classic (FAP) or attenuated adenomatous polyposis (AFAP).
