Does gastric metaplasia always lead to cancer?
Complications from intestinal metaplasia Intestinal metaplasia is believed to be a precancerous lesion that may lead to gastric cancer. If you have intestinal metaplasia, then your risk of getting gastric cancer is increased six times .
Is gastric metaplasia serious?
Intestinal metaplasia can be severe. The transformation of the cells of the gastric lining puts a person at a much higher risk of developing gastric cancer. While it is not possible to avoid some risk factors such as genetics, people can avoid other risk factors, including diet, H. pylori infection, and smoking.
What percentage of intestinal metaplasia becomes cancer?
Atrophic gastritis, intestinal metaplasia, mild-moderate dysplasia, and severe dysplasia were associated with annual incidences of gastric cancer of 0.1%, 0.25%, 0.6%, and 6.0%, respectively.
What is cardiac metaplasia?
Cardiac mucosa has intestinal features, and appears to be the precursor of intestinal metaplasia with goblet cells. In apparently normal individuals, cardiac mucosa typically is present in a narrow band, less than 3 mm in extent, on the columnar side of the squamo-columnar junction at the end of the esophagus.
Does intestinal metaplasia go away?
In the long term, with follow up of at least five years, there is epidemiological evidence that IM may be reversible although a combination of antioxidant agents and eradication of H pylori may be necessary to achieve this.
What is gastric metaplasia?
Gastric intestinal metaplasia (GIM) is an intermediate precancerous gastric lesion in the gastric cancer cascade of chronic gastritis, atrophic gastritis, intestinal metaplasia (IM), dysplasia, and adenocarcinoma [1]. Although the risk of gastric cancer is increased in patients with GIM, the absolute risk is modest.
Is dysplasia worse than metaplasia?
Universally, metaplasia is a precursor to low-grade dysplasia, which can culminate in high-grade dysplasia and carcinoma. Improved clinical screening for and surveillance of metaplasia might lead to better prevention or early detection of dysplasia and cancer.
Why does metaplasia happen?
Metaplasia is the replacement of one differentiated somatic cell type with another differentiated somatic cell type in the same tissue. Typically, metaplasia is triggered by environmental stimuli, which may act in concert with the deleterious effects of microorganisms and inflammation.
What does metaplasia mean medically?
(meh-tuh-PLAY-zhuh) A change of cells to a form that does not normally occur in the tissue in which it is found.
How can you reverse intestinal metaplasia?
After confirming a diagnosis of intestinal metaplasia, the doctor can begin treatment. Currently, the most effective treatment is to remove the H. pylori infection completely. This removal is done in combination with the use of antioxidant agents. Studies have shown this to be an effective way of trying to reverse intestinal metaplasia.
Does gastric metaplasia always lead to gastric cancer?

While it is not possible to avoid some risk factors such as genetics, people can avoid other risk factors, including diet, H. pylori infection, and smoking.
What is incomplete intestinal metaplasia?
The other variation of focal metaplasia is commonly referred to as incomplete intestinal metaplasia. In this form, the transformed cells are similar to the microscopic structures found in the large intestine. The affected organ generally contains goblet cells and rudimentary villi, often associated with the colon.
