CRP and adenoma: Despite the efforts in the screening CRC/CRP in target groups (e.g., individuals over 50 years of age) during the past 2 decades, 25% of adenomas or pre-cancerous lesions may be missed in conventional colonoscopies even if performed by expert gastroenterologists.9,10 Over the past few decades, several measures have been developed and recommended to evaluate the quality of colonoscopy for the diagnosis of polyps and colon cancers.11 An important quality measure is the adenoma detection rate (ADR).
