Barrett esophagus

An abnormal change (metaplasia) in the cells of the inferior portion of the esophagus. The normal squamous epithelium lining of the esophagus is replaced by metaplastic columnar epithelium. Columnar epithelium refers to a cell type that is typically found in more distal parts of the gastrointestinal system. [from HPO]

Concept ID:

Barrett esophagus

Barrett esophagus, or Barrett metaplasia, describes the phenotypic change of normal esophageal squamous epithelium to a columnar and intestinal-type epithelium. This metaplastic change is important because patients with Barrett esophagus have an increased risk of esophageal adenocarcinoma. The main cause of Barrett metaplasia is gastroesophageal reflux (GER; 109350). The retrograde movement of acid and bile salts from the stomach into the esophagus in this disease causes prolonged injury to the esophageal epithelium and induces chronic esophagitis, which in turn is believed to trigger the pathologic changes (summary by Wong et al., 2005). [from GTR]

Severe

Having a high degree of severity. For quantitative traits, a deviation of between four and five standard deviations from the appropriate population mean. [from HPO]

Concept ID:
C0205082
Qualitative Concept
6.

Dysplasia

A usually neoplastic transformation of the cell, associated with altered architectural tissue patterns. The cellular changes include nuclear and cytoplasmic abnormalities. Molecular genetic abnormalities are also often found and, in some instances, may lead to cancer. [from NCI]

MedGen UID:
87191
Concept ID:
C0334044
Pathologic Function
7.

Tretinoin

A naturally-occurring acid of retinol. Tretinoin binds to and activates retinoic acid receptors (RARs), thereby inducing changes in gene expression that lead to cell differentiation, decreased cell proliferation, and inhibition of tumorigenesis. This agent also inhibits telomerase, resulting in telomere shortening and eventual apoptosis of some tumor cell types. The oral form of tretinoin has teratogenic and embryotoxic properties. [from NCI]

Condition, Preneoplastic

cellular state in which there is evidence of intracellular changes which could lead to a neoplastic condition. [from CRISP]

Retinol

The fat soluble vitamin retinol. Vitamin A binds to and activates retinoid receptors (RARs), thereby inducing cell differentiation and apoptosis of some cancer cell types and inhibiting carcinogenesis. Vitamin A plays an essential role in many physiologic processes, including proper functioning of the retina, growth and differentiation of target tissues, proper functioning of the reproductive organs, and modulation of immune function. [from NCI]

13.

Retinoid

A group of agents that includes retinol (Vitamin A) and related compounds with potential antineoplastic and/or chemopreventive activities. A retinoic acid agent binds to and/or activates specific nuclear retinoic acid receptors (RARs) and retinoid X receptors (RXRs), thereby modulating transcription of genes responsible for cell differentiation and proliferation. A retinoic acid agent may exhibit immunomodulatory and anti-inflammatory properties and may inhibit ornithine decarboxylase, resulting in a decrease in polyamine synthesis and keratinization. (NCI04) [from NCI]

Precancerous Condition

A pathological process with signs indicating it may become cancerous. Representative examples include leukoplakia, dysplastic nevus, actinic keratosis, xeroderma pigmentosum, and intraepithelial neoplasia. [from NCI]

Vitamin A

Retinol and derivatives of retinol that play an essential role in metabolic functioning of the retina, the growth of and differentiation of epithelial tissue, the growth of bone, reproduction, and the immune response. Dietary vitamin A is derived from a variety of CAROTENOIDS found in plants. It is enriched in the liver, egg yolks, and the fat component of dairy products. [from MeSH]

Gastrointestinal disease

A non-neoplastic or neoplastic disorder that affects the gastrointestinal tract, anus, liver, biliary system, and pancreas. [from NCI]

Disorder of esophagus

A non-neoplastic or neoplastic disorder that affects the esophagus. Representative examples of non-neoplastic disorders include esophagitis and esophageal ulcer. Representative examples of neoplastic disorders include carcinomas, lymphomas, and melanomas. [from NCI]

Abnormality of the gastrointestinal tract

An abnormality of the gastrointestinal tract. [from HPO]

Carotinoid

A class of hydrocarbons (carotenes) and their oxygenated derivatives which exhibit chemopreventive properties. Carotenoids are pigments found in green, yellow, and leafy vegetables, and yellow fruits. The pigments are fat-soluble, unsaturated aliphatic hydrocarbons functioning as provitamins and are converted to vitamin A through enzymatic processes in the intestinal wall. [from NCI]
