The most common type is Gastric Adenocarcinoma. It is actually the most common type of cancer (other than skin cancer) worldwide. Gastric Adenocarcinoma is more common in men, Asians, Africans, and Hispanics. There is a very high incidence in Japan, Chile, Colombia, and Central America. The second leading cause of stomach disease is non-Hodgkin's Lymphoma.

- The site of the cancer is classified on the basis of its relationship to the long axis of the stomach. Approximately 40% of cancers develop in the lower part, 40% in the middle part, and 15% in the upper part, and 10% involve more than one part of the organ. Over the past half century or so, there has been a steady decline in gastric cancer incidence and gastric cancer deaths in men and women in the United States. Most of this decrease has occurred in the intestinal type of gastric cancer. In addition, the incidence of gastric cardia adenocarcinoma has actually gradually increased.

Gastric carcinoma is the most common gastrointestinal malignancies worldwide.
Causes
Several factors are implicated in the development of gastric cancer, including diet, Helicobacter pylori infection, previous gastric surgery, pernicious anemia, adenomatous polyps, chronic atrophic gastritis, prior radiation exposure or inherited syndromes. Gastric cancer may often be multifactorial involving both inherited predisposition and environmental factors.

 |
|
|
Video Endoscopic Sequence 3 of 5.
Causes
- Diet
- A diet rich in pickled vegetables, salted fish, excessive dietary salt, and smoked meats correlates with an increased incidence of gastric cancer.
- A diet that includes fruits and vegetables rich in vitamin C may have a protective effect.

Causes
- Smoking
- Smoking is associated with an increased incidence of stomach cancer in a dose-dependent manner, both for number of cigarettes and duration of smoking.
- Smoking increases the risk of cardiac and noncardiac forms of stomach cancer. Cessation of smoking reduces the risk.
- A meta-analysis of 40 studies estimated that the risk was increased by approximately 1.5- to 1.6-fold and was higher in men.

- Helicobacter pylori infection
- Chronic bacterial infection with H pylori is the strongest risk factor for stomach cancer.
- H pylori may infect 50% of the world's population, but much less than 5% of infected individuals develop cancer. It may be that only a particular strain of H pylori, one of which is capable of producing the greatest amount of inflammation, is especially associated with the risk of malignancy. The full malignant transformation of affected parts of the stomach may require that the human host have a particular genotype of interleukin-Iβ to cause the increased inflammation and an increased suppression of gastric acid secretion.
- H pylori infection is associated with chronic atrophic gastritis, and patients with a history of prolonged gastritis have a 6-fold increase in their risk of developing gastric cancer. Interestingly, this association is particularly strong for tumors located in the antrum, body, and fundus of the stomach but does not seem to hold for tumors originating in the cardia.
- Previous surgery is implicated as a risk factor. The rationale is that surgery alters the normal pH of the stomach, which may in turn lead to metaplastic and dysplastic changes in luminal cells.
- Retrospective studies demonstrate that a small percentage of patients who undergo gastric polyp removal have evidence of invasive carcinoma within the polyp. This discovery has led some researchers to conclude that polyps might represent premalignant conditions.

Video Endoscopic Sequence 6 of 6.
NBI displays enhanced images of capillaries in the mucosal surface and detailed mucosal texture by irradiating two narrow wave bands (390–445 nm/530–550 nm) which are strongly absorbed by circulating hemoglobin. If signal processing is performed using a pseudo-narrow band image, the state of mucosa tissues and observation conditions influence the results and good effects cannot be obtained. However, with NBI, the wavelength of the irradiating light itself is altered, and capillaries in the mucosal surface and detailed mucosal texture can thus be processed effectively and stably.

Worldwide, stomach cancer (also referred to as gastric cancer) remains one of the most common forms of cancer, affecting approximately 800,000 new individuals annually. However, the rate of stomach cancer has been declining in the United States and western Europe over the past half-century, a trend which has been felt attributable in large part to changes in diet during this period of time. Interestingly, the incidence of cancers located in different portions of the stomach appear to be heading in opposite directions: while those located in the more distal (lower) portion of the stomach have been declining in incidence, there has actually been an increase in cases occurring in the proximal portion of the stomach (closer to the esophagus) and at the gastroesophageal junction.

Gastric Adenocarcinoma.
Pathophysiology: The accepted pathway involves transitions from gastritis to gastric atrophy to metaplasia to dysplasia and, finally, to cancer.
Several dietary and environmental factors may influence this pathway.
- Hypochlorhydria: This condition occurs in gastric atrophy and promotes bacterial colonization of the stomach. It leads to increased nitrite formation, which may have a mutagenic effect on the atrophic gastric mucosa.
- Helicobacter pylori: Antral gastritis caused by H pylori has been linked to the development of gastric cancer. Patients with H pylori gastritis are 3-6 times more likely to develop gastric cancer than individuals without the infection.
- Certain foods: Starch, pickled vegetables, salted fish and meat, smoked foods, and salt have all been implicated.
- Cigarette smoking: Those who smoke more than 30 cigarettes per day have a 5-fold increased risk of gastric carcinoma.

CT is primarily used to preoperatively assess patients with gastric carcinoma. CT is to assess the presence and extent of extragastric spread. This information is vital in deciding between palliative surgery and curative radical surgery. Therefore, the main role of CT is to identify patients who would not benefit from radical surgery. Thus, CT is used to stage the tumor and also to monitor the response to treatment.

ALTHOUGH GASTRIC CARCINOMA occurs with reduced frequency, it is still a prevalent disease. Most gastric carcinomas are classified as adenocarcinomas due to glandular growth pattern and/or presumed occurrence of mucin intracellularly Mucin is often identified by periodic acid-Schiff (PAS) and/or alcian blue (AB) positivity. However, neither of these histochemical methods is specific for mucins. Both methods are based upon the identification of glycoproteins. We have previously described that a proportion of gastric carcinomas, particularly of the diffuse type according to Laurén 1965 are neuroendocrine derived and probably of enterochromaffin-like (ECL) cell origin. The so-called signet ring cell carcinomas belong to the diffuse type of gastric carcinomas.

Gastric linitis plastica is a very particular malignant gastric tumor different from the usual gastric adenocarcinoma. Linitis plastica refers to the diffuse proliferation of the connective tissue, resulting in tissue thickening so that the stomach is constricted and rigid. Pathological exams reported a strong connective stroma-reaction associated with a malignant glandular proliferation of independent cells (signet-ring cells), invading all the layers of the digestive tract, the mucosa being usually save not affected. Diagnosis is based on the association of pathological results findings revealed by endoscopic, endoscopic ultrasonography, radiological and surgical examinations. Opposed to the adenocarcinoma, Helicobacter Pylori seems not to be associated with the occurrence of gastric linitis.

Diet appears to play a major role in the development of stomach cancer. Nitroso compounds such as nitrites (found in smoked meats and fish) and nitrates (used in food preservatives), and high salt intake, likely contribute to this disease, whereas fresh vegetables are protective. The question of whether green tea also has any protective effects remains debatable.

A bacteria called Helicobacter pylori represents an additional risk factor for gastric cancer, particularly those cancers occurring in the distal portion (antrum) of the stomach. This infection may lead to inflammation of the superficial layer of the stomach, inducing changes in the cells that line the stomach which eventually results in cancer. It should be stressed, however, that most patients with H. pylori infection do not develop gastric cancer. The independent association between peptic ulcer disease (PUD) and stomach cancer remains questionable, although H. pylori infection is known to be a risk factor for both. Autoimmune gastritis (associated with lack of hydrochloric acid secretion in the stomach and pernicious anemia), and adenomatous gastric polyps, represent other precursors that increase a person's risk of developing stomach cancer. Chronic GERD (gastroesophageal reflux disease) can cause damage to the tissue lining the lower portion of the esophagus and first portion of the stomach (cardia), resulting in the development of cancer at the G-E junction.

Gastric adenocarcinoma may spread via direct extension through the stomach wall into adjacent organs (spleen, pancreas, colon, esophagus, diaphragm). Alternatively, cancer cells may spread through lymphatic channels to lymph nodes in the abdomen or chest, and even rarely to the left supraclavicular (neck) lymph nodes. Metastases through the bloodstream can result in the cancer spreading to distant organs such as liver, lungs, and bones. Direct peritoneal seeding can produce malignant ascites (fluid accumulation in the abdomen). In women, stomach cancer can spread to the ovaries, referred to as a Krukenberg tumor.
