INTRODUCTION: Cancer screening guidelines should be based on the best available evidence, presenting both the benefits and harms of screening in a manner applicable to stakeholders. How the potential benefits and harms of screening are presented determine the intent of guideline developers and the delivery of recommendations. Therefore, we will systematically review the cancer screening guidelines for Koreans to evaluate the presentation and detailed ways of the benefits and harms of the recommended cancer screening practices. METHODS AND ANALYSIS: To identify cancer screening guidelines for Koreans, we will search international electronic databases, including MEDLINE, Embase and domestic literature databases (Korean Studies Information Service System, Research Information Sharing Service, KoreaMED, Korean Medical Database, National Assembly Library and Korea Institute of Science and Technology Information) as well as guideline databases (Guideline International Network, National Institute for Health and Care Excellence, Turning Research Into Practice medical database, WHO guidelines and Korean Medical Guideline Information Center), from inception to November 2022. We will include cancer screening guidelines for healthcare practitioners and patients. Furthermore, we will focus on the most updated guidelines when multiple versions of guidelines are available for a specific intervention and cancer pairs from the same development group. Two reviewers will independently and in duplicate conduct reference screening and data extraction. Data will be extracted based on recommendations from each guideline and how their benefits and harms are presented. The general characteristics of cancer screening guidelines, including cancer type, recommended screening methods, certainty of evidence, direction and strength of recommendation, will be collected. In addition, we will obtain key information on the presentation of the benefits and harms of screening interventions, including quantification of their relative and absolute effects of screening interventions. Finally, our findings will be presented descriptively, and a summary of the results will be provided. ETHICS AND DISSEMINATION: Ethics approval is not required as we will only use published materials. We will disseminate our findings through publication in peer-reviewed journals.
