Gastric cancer remains a difficult disease to cure in Western countries, primarily because most patients present with advanced disease. Even patients who present in the most favorable condition and who undergo curative surgical resection often die of recurrent disease.

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.

Most patients are elderly at diagnosis. The median age at diagnosis is 65 years (range 40-70 y). The gastric cancers that occur in younger patients may represent a more aggressive variant.

Although the incidence of stomach cancer has declined dramatically in the United States and Western Europe in the last 50 years, the disease remains a serious problem in much of the rest of the world, where it's a leading cause of cancer death.

 dramatically in the United States and Western Europe in
 the last 50 years, the disease remains a serious problem in
 much of the rest of the world, where it's a leading cause of
 cancer death.

 

This global variation is almost certainly linked to two factors that play a major role in the development of stomach cancer: Infection with Helicobacter pylori (H. pylori) bacteria and the type of diet.

Stomach cancer is more readily treated when caught early. Unfortunately, by the time it causes symptoms, the disease is often at an advanced stage and may have spread beyond the stomach. Yet there is encouraging news. You can reduce your risk of this serious cancer by making a few changes in your lifestyle.

 morbidity.

Enormous malign ulceration is seen.

 Advanced lesions have already invaded the muscularis propria.
 They are associated with metastases to regional lymph nodes or
 to local or distant structures.

 Early gastric lesions are confined to the mucosa or submucosa.
 Most reports are from Japan, as a result of mass screening there.
 Patients with these tumors have a 5-year survival rate of 90%.

 

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.Several precancerous conditions are recognized: Chronic atrophic gastritis Pernicious anemia Previous partial gastrectomy, Ménétrier disease Gastric dysplasia Adenomatous polyps (20% of all gastric polyps) Hereditary factors.

  • 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.

Gastric Cancer is the second most frequent cancer in this country,second only to carcinoma of the cervix.

Another image and video of that small neoplasia, however The cat scan displays that the liver is infiltrated with metastases. 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.
