The average length of follow-up was two years. Two hundred and sixty five cases of gastric ulcer were studied of which 37 proved to be malignant (14%). Presenting complaints of anorexia, weight loss, nausea and\/or vomiting, and multiple (greater than 3) symptoms, were commoner in the malignant ulcer group. Ulcer site and the presence of coexisting duodenal ulceration were largely unhelpful in deciding the status of an ulcer. Malignant ulcers tended to be large (greater than 1 cm diameter). Radiology was highly unreliable in distinguishing benign from malignant ulcers. Visual inspection at endoscopy was more reliable, but associated with a tendency to over-diagnose malignancy. False positive biopsies were uncommon (two cases). Three cases of clinically unsuspected superficial gastric carcinoma were revealed. Repeated endoscopy and biopsy of all gastric ulcers until they are completely healed is advised.<\/jats:p>","DOI":"10.1136\/gut.21.1.9","type":"journal-article","created":{"date-parts":[[2007,9,18]],"date-time":"2007-09-18T17:41:31Z","timestamp":1190137291000},"page":"9-17","source":"Crossref","is-referenced-by-count":52,"title":["Gastric cancer detection in gastric ulcer disease."],"prefix":"10.1136","volume":"21","author":[{"given":"R A","family":"Mountford","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P","family":"Brown","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P R","family":"Salmon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C","family":"Alvarenga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C S","family":"Neumann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A E","family":"Read","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1980,1,1]]},"reference":[{"key":"ref_1","first-page":"512","article-title":"Endoscopic diagnosis in advanced carcinoma of the stomach (Abstract)","volume":"15","author":"Ashby, B.S.","year":"1974","unstructured":"Ashby, B.
