There is a risk of development of cancer with fundic gland polyposis, [22] but it varies based on the underlying cause of the polyposis. [4] The risk is highest with congenital polyposis syndromes, and is lowest in acquired causes. [4] [23] As a result, it is recommended that patients with multiple fundic polyps have a colonoscopy to evaluate ...
A fundic gland polyp is a type of polyp, found in the fundus of the stomach. Fundic gland polyps are found in 0.8 to 1.9% of patients who undergo esophagogastroduodenoscopy, and are more common in middle-aged women. [2] The risk of malignancy is very low or none, when sporadic. [3]
Fundic gland polyp: Fundus of stomach: Cystically dilated glands lined by chief cells, parietal cells and mucinous foveolar cells. [5] Very low or none, when sporadic. [6] Fundic gland polyposis: Sessile serrated adenoma: Colorectal Similar to hyperplastic with hyperserration, dilated/branched crypt base, prominent mucin cells at crypt base Yes
Fundic gland polyposis is a medical syndrome where the fundus and the body of the stomach develop many fundic gland polyps. Pernicious anemia is caused when damaged parietal cells fail to produce the intrinsic factor necessary for the absorption of vitamin B12. This is the most common cause of vitamin B12 deficiency.
The change allows numerous cells of the intestinal wall to develop into potentially cancerous polyps when they would usually reach the end of their life; inevitably one or more will eventually progress and give rise to cancer (7% risk by age 21, rising to 87% by age 45 and 93% by age 50). These gene changes do not trigger cancer, but rather ...
Some substances cause cancer primarily through their physical, rather than chemical, effects on cells. [32] A prominent example of this is prolonged exposure to asbestos, naturally occurring mineral fibers which are a major cause of mesothelioma, which is a cancer of the serous membrane, usually the serous membrane surrounding the lungs. [32]
Recent research has shown that autoimmune metaplastic atrophic gastritis (AMAG) is a result of the immune system attacking the parietal cells. [6]Environmental metaplastic atrophic gastritis (EMAG) is due to environmental factors, such as diet and H. pylori infection.
Long-term use of PPIs is associated with the development of benign polyps from fundic glands (which is distinct from fundic gland polyposis); these polyps do not cause cancer and resolve when PPIs are discontinued. [33] There is concern that use of PPIs may mask gastric cancers or other serious gastric problems. [33]
