View available downloads The stomach is part of the digestive system, located between the oesophagus and the small intestine. It secretes enzymes and gastric acid to aid in food digestion, as well as the intrinsic factor necessary for absorption of vitamin B12, and acts as a receptacle for masticated food, which is sent to the small intestines though muscular contractions.

The body of the stomach is lined with a mucous membrane consisting of columnar epithelial cells and glands, surrounded by muscle. In total, this report analyses 89 studies from around the world, comprising Incidence and survival rates Stomach cancer — also known as gastric cancer — is the fifth most common cancer worldwide.

Aroundnew cases of stomach cancer were recorded globally inaccounting for seven per cent of all new cases of cancer. Men are twice as likely as women to develop stomach cancer, and it is more common in older adults over the age of Stomach cancer is the third most common cause of death from cancer.

Symptoms often only appear at a late stage, which contributes to a poor prognosis. For example, in Europe and the US the five-year survival rate of stomach cancer is about 25 to 28 per Stomach and bladder cancer essay, increasing to about 63 per cent if the cancer is diagnosed at an early stage.

However, these survival rates are worse in less developed countries where stomach cancer is typically detected at a more advanced stage.

About 70 per cent of cases of stomach cancer occur in less developed countries with about half of all cases in Eastern Asia, particularly China.

Globally, overall incidence rates of stomach cancer are declining. This is attributed to a decrease in Helicobacter pylori infection and the use of refrigeration to preserve foods rather than using salt. Stomach cancer is classified into different types according to location of the tumour.

Stomach cardia cancer occurs at the top part of the stomach closest to the oesophagus, and stomach non-cardia cancer occurs in all other areas of the stomach.

Also, infection with Epstein-Barr virus is under investigation as a contributor to stomach cancer. Other industries including rubber manufacturing, coal mining, metal processing and chromium production have also been associated with an elevated risk of this cancer.

Pathogenesis The lining of the stomach is exposed to carcinogens present in foods, which are held in the stomach for a period of up to five hours during digestion. More than 95 per cent of stomach cancers are adenocarcinomas, with primary gastric lymphoma being the second most common malignancy.

Pathogenesis and aetiology differ between cardia and non-cardia cancers. Chronic gastritis, inflammation brought about by a variety of environmental factors and ageing can eventually lead to changes in the characteristics of the stomach mucosal cells.

These changes appear to be precursor conditions to the development of non-cardia cancer. Non-cardia cancers may be either intestinal well-differentiated or diffuse undifferentiated, from mucus-producing cells. Intestinal types commonly undergo a cascade from normal mucosa through chronic gastritis to atrophic gastritis, intestinal dysplasia, and then adenocarcinoma.

This progression may take several years. Intestinal types are more common in males and older adults, whereas diffuse types may occur in all age groups with equal sex distribution and show more rapid progression and poorer prognosis.

Infection appears to interact with dietary factors. One pooled analysis reported an increased stomach cancer risk with H. A rare, genetically inherited form of diffuse stomach cancer also exists, which is unrelated to H.

Rare hereditary variants contribute to about 1—3 per cent of stomach cancers. The pathogenesis of cardia cancer is less well established, although it is associated with inflammation of the cardia. There are similarities between cardia cancer and oesophageal adenocarcinoma, which is inversely associated with H.

Cardia cancer may, in some populations, be inversely associated with H. A dual aetiology, with some tumours linked to H.
