We determined the actual risk for advanced neoplasia in relation to lapsed time between colonoscopies in people enrolled in a structured surveillance program. This risk information can be used to guide the selection of optimal surveillance intervals.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients were recruited into programs at two major tertiary hospitals, with a personal or family history of advanced neoplasia. Five thousand one hundred forty\u2010one patients had an index and one or more surveillance colonoscopies. Fifty\u2010one percent had a family history of colorectal neoplasia while the remainder had a personal history.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Patients with an immediately prior colonoscopy result (prior result) of advanced adenoma had a risk for advanced neoplasia 7.1 times greater than those with a normal prior result. Cancer as a prior result did not confer a greater risk than either a hyperplastic polyp or a nonadvanced adenoma. Being female reduced risk, age increased risk. Only a family history of a first\u2010degree relative diagnosed under 55, or definite or suspected hereditary nonpolyposis colorectal cancer (<jats:styled-content style=\"fixed-case\">HNPCC<\/jats:styled-content>) conferred an increased risk over a personal history of advanced neoplasia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Most family history categories did not confer excess risk above personal history of advanced neoplasia. A prior cancer poses less of a risk than a prior advanced adenoma. Based on our models, a person with an advanced adenoma should be scheduled for colonoscopy at 3 years, corresponding to a 15% risk of advanced neoplasia for a male aged under 56. Guidelines should be updated that uses a 15% risk as a benchmark for calculating surveillance intervals.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jgh.12904","type":"journal-article","created":{"date-parts":[[2015,1,22]],"date-time":"2015-01-22T10:37:33Z","timestamp":1421923053000},"page":"1147-1154","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Ideal colonoscopic surveillance intervals to reduce incidence of advanced adenoma and colorectal cancer"],"prefix":"10.1111","volume":"30","author":[{"given":"Norm M","family":"Good","sequence":"first","affiliation":[{"name":"CSIRO Digital Productivity Royal Brisbane and Women's Hospital  Herston Queensland Australia"},{"name":"Australian e\u2010Health Research Centre Royal Brisbane and Women's Hospital  Herston Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Finlay A","family":"Macrae","sequence":"additional","affiliation":[{"name":"Colorectal Medicine and Genetics The Royal Melbourne Hospital  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Graeme P","family":"Young","sequence":"additional","affiliation":[{"name":"Flinders Centre for Innovation in Cancer Flinders University  Bedford Park South Australia Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"O'Dywer","sequence":"additional","affiliation":[{"name":"Australian e\u2010Health Research Centre Royal Brisbane and Women's Hospital  Herston Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masha","family":"Slattery","sequence":"additional","affiliation":[{"name":"Colorectal Medicine and Genetics The Royal Melbourne Hospital  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William","family":"Venables","sequence":"additional","affiliation":[{"name":"CSIRO Digital Productivity Ecosciences Precinct  Dutton Park Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Trevor J","family":"Lockett","sequence":"additional","affiliation":[{"name":"CSIRO Food &amp; Nutrition Riverside Corporate Park  North Ryde New South Wales Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marilla","family":"O'Dwyer","sequence":"additional","affiliation":[{"name":"I&amp;D Rio Tinto  Brisbane Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,6,10]]},"reference":[{"key":"e_1_2_5_2_1","volume-title":"Cancer Incidence Projections Australia 2002 to 2011","author":"AIHW","year":"2005"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2012.06.001"},{"issue":"3","key":"e_1_2_5_4_1","first-page":"SE151","article-title":"European guidelines for quality assurance in colorectal cancer screening and diagnosis.
