[Correspondence] Colorectal adenomas, surveillance, and cancer – Authors' reply

The primary aim of surveillance is to reduce colorectal cancer incidence to avoid morbidity and mortality from the disease. Current guidelines stratify patients with adenomas into risk groups, but these guidelines are based on advanced adenoma detection at surveillance. Advanced adenomas vary in malignant potential and diagnosis can occur only in those attending surveillance. Data that use colorectal cancer as the endpoint are thus needed.
