Dysplasia in Barrett's esophagus. 1985

H G Schmidt, and R H Riddell, and B Walther, and D B Skinner, and J F Riemann

In a retrospective histological study, resected specimens obtained from 23 patients with adenocarcinoma in Barrett's esophagus (Group I) and endoscopic multiple (step) biopsies from 38 patients without carcinoma in Barrett's esophagus (Group II) were investigated for dysplastic changes. Dysplasia was most frequently found in the type of mucosa comprising intestinal metaplasia. There seem to be two pathways to dysplasia in Barrett's esophagus. In Group I dysplasia was found in 18 out of 23, and in Group II in 2 out of 38 patients. In Barrett's esophagus, dysplasia may be considered not only a precursor of carcinoma, but also a marker for coexisting carcinoma.

D001471	Barrett Esophagus	A condition with damage to the lining of the lower ESOPHAGUS resulting from chronic acid reflux (ESOPHAGITIS, REFLUX). Through the process of metaplasia, the squamous cells are replaced by a columnar epithelium with cells resembling those of the INTESTINE or the salmon-pink mucosa of the STOMACH. Barrett's columnar epithelium is a marker for severe reflux and precursor to ADENOCARCINOMA of the esophagus.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
