Lee, Hong, Kim, Kim, Kim, Hong, Yang, Shin, Lee, Kim, Park, Kim, Yang, Kim, Jeon, and Multi-Society Task Force for Development of Guidelines for Colorectal Polyp Screening, Surveillance and Management: Korean Guidelines for Colorectal Cancer Screening and Polyp Detection


Colorectal cancer is currently the second most common cancer among Korean males and the fourth most common among females. Since the majority of colorectal cancer case present following the prolonged transformation of adenomas into carcinomas, early detection and removal of colorectal adenomas are vital methods in its prevention. Considering the increasing incidence of colorectal cancer and polyps in Korea, it is very important to establish national guidelines for colorectal cancer screening and polyp detection. The proposed guidelines have been developed by the Korean Multi-Society Task Force using evidence-based methods. Systematic reviews and meta-analyses have been used to form the statements contained in the guidelines. This paper discusses the epidemiology of colorectal cancers and adenomas in Korea as well as optimal methods for screening of colorectal cancer and detection of adenomas including fecal occult blood tests, radiologic tests, and endoscopic examinations.
