Adenoma, advanced adenoma and colorectal cancer prevalence in asymptomatic 40 to 49-year-olds with a first-degree family history of colorectal cancer

摘要

First-degree relatives (FDRs) of patients with colorectal cancer (CRC) have an increased CRC risk. Few studies have addressed if adenoma and advanced adenoma risk is increased among individuals, 40-49 years of age, with a family history of CRC. Therefore, the aim of the study was to define the prevalence and location of adenoma, advanced adenoma and CRC, according to age, in asymptomatic individuals with a family history of CRC.
