Evidenced-Based Screening Strategies for a Positive Family History

Jennifer M Kolb et al. Gastrointest Endosc Clin N Am. 2020 Jul.

Abstract

The most commonly recognized high-risk group for colorectal cancer (CRC) is individuals with a positive family history. It is generally recognized that those with a first-degree relative (FDR) with CRC are at a 2-fold or higher risk of CRC or advanced neoplasia. FDRs of patients with advanced adenomas have a similarly increased risk. Accordingly, all major US guidelines recommend starting CRC screening by age 40 in these groups. Barriers to screening this group include patient lack of knowledge on family and polyp history, provider limitations in collecting family history, and insufficient application of guidelines.

Keywords: Advanced adenoma; Colon cancer screening; Colorectal cancer; First-degree relative; Second-degree relative.
