We evaluated the characteristics of PCCRC in average-risk Korean subjects. Materials and Methods: This study included subjects who were &amp;ge;50 years of age and had undergone a first completed colonoscopy between January 2001 and December 2004, at which no baseline adenoma had been detected, followed by a second colonoscopy 1&amp;ndash;5 years later. The incidences and characteristics of advanced neoplasia in these subjects were assessed. Results: A total of 343 subjects underwent follow-up colonoscopy within 5 years. Seventy-three (21.3%) subjects were found to have at least one adenoma on follow-up colonoscopy. Advanced adenoma was found in eight (2.3%) subjects, and non-advanced adenomas were found in 65 (19.0%). Five (1.5%) subjects were diagnosed with invasive CRC following a normal colonoscopy. The putative reason for PCCRCs was missed lesions in two (40.0%) subjects and a new cancer in three (60.0%). Conclusion: The risk of advanced neoplasia (including PCCRCs) within 5 years after a normal baseline colonoscopy in our cohort was not low. Considering that 40% of PCCRCs were attributable to missed lesions, our results emphasize the need for technical improvement of colonoscopic examinations to improve adenoma detection.<\/jats:p>","DOI":"10.5152\/tjg.2015.150286","type":"journal-article","created":{"date-parts":[[2015,12,17]],"date-time":"2015-12-17T03:37:59Z","timestamp":1450323479000},"page":"17-22","source":"Crossref","is-referenced-by-count":4,"title":["Post-colonoscopy colorectal cancers in average-risk Korean subjects with a normal initial colonoscopy"],"prefix":"10.5152","volume":"27","author":[{"given":"Han Hee","family":"Lee","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seung Kyoung","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyun Ho","family":"Choi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyung-Keun","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sung Soo","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiun-Suk","family":"Chae","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyunjung","family":"Cho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young-Seok","family":"Cho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3111","published-online":{"date-parts":[[2016,1,15]]},"container-title":["Turkish Journal of Gastroenterology"],"original-title":[],"link":[{"URL":"https:\/\/www.turkjgastroenterol.org\/index.php\/tjg\/article\/download\/2830\/2511","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T11:34:42Z","timestamp":1777376082000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.turkjgastroenterol.org\/index.php\/tjg\/article\/view\/2830"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,1,15]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2016,1,15]]}},"URL":"https:\/\/doi.org\/10.5152\/tjg.2015.150286","relation":{},"ISSN":["2148-5607"],"issn-type":[{"value":"2148-5607","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,1,15]]}}}
