Intestinal metaplasia is the transformation of epithelium (usually of the stomach or the esophagus) into a type of epithelium resembling that found in the intestine. In the esophagus, this is called Barrett's esophagus .
The presence of intestinal metaplasia in Barrett's esophagus represents a marker for the progression of metaplasia towards dysplasia and eventually adenocarcinoma. This factor combined with two different immunohistochemical expression of p53, Her2 and p16 leads to two different genetic pathways that likely progress to dysplasia in Barrett's ...
It begins with normal tissue and long-term inflammation causes the cells to undergo atrophy, metaplasia, dysplasia, and finally, becomes an adenoma or carcinoma. [2] Given this progression, these lesions represent a potentially cancerous growths and an important opportunity to prevent gastrointestinal cancer.
A diagnosis of Barrett's esophagus is confirmed by a metaplastic change of the esophageal mucosa from squamous to columnar mucosa with intestinal metaplasia. Barrett's esophagus is the dominant pre-malignant lesion of esophageal adenocarcinoma, [18] and has prevalent epigenetic alterations. [19]
Intestinal metaplasia is a premalignant condition that increases the risk for subsequent gastric cancer. [4] Intestinal metaplasia lesions with an active DNA damage response will likely undergo extended latency in the premalignant state until further damaging hits override the DNA damage response leading to clonal expansion and progression.

Similar to that of the oesophagus, CLE is able to detect early gastric cancer, as well as premalignant conditions, such as gastritis and intestinal metaplasia. [ 1 ] [ 2 ] [ 6 ] CLE can detect and distinguish the stomach pit patterns to identify the disease in accordance with the Miami classification, which was refined in 2016 to include both ...
