The articles are devoted to the following topics: What is organized screening and what is its value; Screening decisions in the opportunistic setting; The National Colorectal Cancer Round Table: Past performance and current and future goals; Proven strategies for increasing screening adherence; Colorectal cancer in persons under age 50: Seeking causes and solutions; Risk stratification strategies: From logistic regression to artificial intelligence; Cost-effectiveness of current screening tests; Quality in colorectal cancer screening; Screening for the serrated pathway; FIT: The world's colorectal cancer screening test; Fecal DNA testing: What has it accomplished and where is it headed; Is bowel preparation without complete colon clearing a viable concept: Update on flexible sigmoidoscopy, CTC, and capsule colonoscopy; Evidenced based screening strategies for a positive family history; Aspirational ADR and ideal colonoscopy performance: How long can we go between colonoscopies; and How Artificial Intelligence will impact colonoscopy and colorectal cancer screening. Readers will come away with the clinical knowledge they need to improve outcomes in colon cancer screening and prevention.

Colonoscopy is the bread and butter for endoscopists and advances in the procedure to reduce time, improve efficiency, and prevent errors are very important for this group. The newest advances look at colonoscopy efficiency and a better way to target tissue sampling, which avoids random biopsies and instead looks at ways to predict areas for sampling. The Guest Editors have selected top experts to provide these important updates and they also address current thinking that questions the continued value of colonoscopies as predictors of colon cancer. The issue will be a very popular one, and it needs to be heavily promoted.
