Thirty-four had positive results of whom thirteen had a cancer and eight an adenomatous polyp (diagnostic yield for neoplasia of 59 per cent). No false negative results occurred, a sensitivity of 100 per cent, and only 21 false positives occurred, a specificity for malignancy of 84 per cent. Subjects attending outpatients should be offered occult blood testing; those with a positive test should undergo colonoscopy. The cost-benefit of such a scheme is emphasized.<\/jats:p>","DOI":"10.1002\/bjs.1800721020","type":"journal-article","created":{"date-parts":[[2007,3,3]],"date-time":"2007-03-03T02:24:23Z","timestamp":1172888663000},"page":"835-837","source":"Crossref","is-referenced-by-count":15,"title":["An assessment of occult blood testing to determine which patients with large bowel symptoms require urgent investigation"],"prefix":"10.1093","volume":"72","author":[{"given":"P A","family":"Farrands","sequence":"first","affiliation":[{"name":"University Surgical Unit, Southampton General Hospital , Southampton,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D","family":"O'Regan","sequence":"additional","affiliation":[{"name":"University Surgical Unit, Southampton General Hospital , Southampton,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I","family":"Taylor","sequence":"additional","affiliation":[{"name":"University Surgical Unit, Southampton General Hospital , Southampton,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[1985,10,1]]},"reference":[{"key":"2024092716422750000_bib1","doi-asserted-by":"crossref","first-page":"445","DOI":"10.1136\/gut.25.5.445","article-title":"Colorectal screening by a self-completion questionnaire","volume":"25","author":"Farrands","year":"1984","journal-title":"Gut"},{"key":"2024092716422750000_bib2","doi-asserted-by":"crossref","first-page":"399","DOI":"10.1002\/bjs.1800690714","article-title":"Comparison of rigid and flexible fibreoptic sigmoidoscopy with double contrast barium enema","volume":"69","author":"Vellacott","year":"1982","journal-title":"Br J Surg"},{"article-title":"Cancer Statistics Registration","volume-title":"Office of Population Census and Surveys","year":"1980","key":"2024092716422750000_bib3"},{"key":"2024092716422750000_bib4","first-page":"833","article-title":"Duration of symptoms and prognosis of carcinoma of the colon and rectum","volume":"144","author":"Irvin","year":"1977","journal-title":"Surg Gynecol Obstet"},{"key":"2024092716422750000_bib5","doi-asserted-by":"crossref","first-page":"309","DOI":"10.1016\/S0140-6736(79)90718-9","article-title":"Delay in the diagnosis and treatment of symptomatic colorectal cancer","volume":"i","author":"Holliday","year":"1979","journal-title":"Lancet"},{"key":"2024092716422750000_bib6","first-page":"617","article-title":"Carcinoma of colon and rectum; delay in diagnosis","volume":"148","author":"Nilsson","year":"1982","journal-title":"Acta Chir Scand"},{"key":"2024092716422750000_bib7","doi-asserted-by":"crossref","first-page":"725","DOI":"10.1007\/BF02554983","article-title":"Flexible fibreoptic sigmoidoscopy and double contrast barium enema in the identification of adenomas and cancers of the colon","volume":"26","author":"Farrandas","year":"1983","journal-title":"Dis Colon Rect"}],"container-title":["Journal of British Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fbjs.1800721020","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/academic.oup.com\/bjs\/article-pdf\/72\/10\/835\/59378868\/bjs1800721020.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/bjs\/article-pdf\/72\/10\/835\/59378868\/bjs1800721020.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,9,27]],"date-time":"2024-09-27T16:42:52Z","timestamp":1727455372000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/bjs\/article\/72\/10\/835\/6193365"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1985,10,1]]},"references-count":7,"journal-issue":{"issue":"10","published-online":{"date-parts":[[1985,10,1]]},"published-print":{"date-parts":[[1985,10,1]]}},"URL":"https:\/\/doi.org\/10.1002\/bjs.1800721020","relation":{},"ISSN":["0007-1323","1365-2168"],"issn-type":[{"type":"print","value":"0007-1323"},{"type":"electronic","value":"1365-2168"}],"subject":[],"published-other":{"date-parts":[[1985,10]]},"published":{"date-parts":[[1985,10,1]]}}}
