Objectives

Narrative objectives1

The prevalence, risk factors, clinical significance, and many other aspects of colorectal serrated lesions are not sufficiently understood. The main objective of this study is to examine the risk factors and clinical significance (relationships to simultaneous colorectal cancer and other colorectal lesions) of colorectal serrated lesions after clarifying the prevalence of colorectal serrated lesions, with particular focus on sessile serrated lesions (SSL) by conducting a prospective survey of individuals undergoing colorectal cancer screening at multiple centers in the Asia-Pacific region.

Basic objectives2

Basic objectives -Others

This study also aims to examine their clinicopathological features, the ability of endoscopy to detect and diagnose these lesions, and the usefulness of such a risk-stratification score as the Asia Pacific Colorectal Screening (APCS) score.

Key inclusion criteria

The study participants will be average-risk individuals (age: 40-74 years) undergoing total colonoscopy (TCS) for colorectal cancer screening for the first time in their lives at the participating institutions, who will receive a full oral explanation of the study using written materials, and who will provide consent in writing. Both individuals undergoing their first TCS for screening purposes and those undergoing first TCS following a positive fecal occult blood test in colorectal cancer screening are included in this study.

Key exclusion criteria

1) Presence of uncontrollable complications, including unstable angina, acute myocardial infarction, heart failure, chronic respiratory disease, bleeding tendency, that make it difficult to safely perform TCS.
2) Clinical symptoms that indicate colorectal cancer, such as hematochezia or abdominal pain.
3) History of treatment for colorectal cancer or colorectal tumor.
4) History of colorectal surgery in which colorectum was resected. (Surgery not involving resection of colorectum such as appendectomy for appendicitis is not included in exclusion criteria)
5) Being from a family with hereditary colorectal cancer.
6) Difficult to survey baseline factors using a questionnaire.
7) Does not provide written consent.
8) Otherwise determined to be unfit by an investigator.
