Gastric Cancer is one of the most frequent malignant tumors in El Salvador, which is responsible for numerous causes of deaths per year.
|Internationally: Adenocarcinoma of the stomach is the second most common cancer worldwide.|
.Risk for gastric (stomach) cancer increases with age. Evidence suggests that high salt intake, a diet low in fresh fruits and vegetables, and infection with H. pylori are associated with an
increased risk of gastric cancer; whereas diets high in whole grain cereals, carotene, and
green tea are associated with a reduced risk of this cancer.
Early detection is often difficult because the symptoms are often vague. They include weakness, fatigue, decreased appetite, indigestion, abdominal pain and bloating. The detection of blood in the stool may indicate a gastric cancer, but can also be caused by many other things. People with continuous gastric symptoms should seek medical attention.
Gastric cancer is one of the most frequent cancers not only in El Salvador but also in the majority of the countries of Latin America as well as in Japan.
|Gastric Cancer is the second most common cause of cancer-related death in the world. Many Asian countries, including Korea, China, Taiwan, and Japan, have very high rates of gastric cancer. More than 22,000 new cases will be diagnosed this year in the United States, making gastric cancer the fourteenth most common cancer in this country. while in the US, the incidence of stomach cancers has actually decreased over the past decade, accounting for approximately 21,000 new cases and 13,000 cancer-related deaths last year. Some of this decrease may be attributable to widespread antimicrobial therapy for eradication of Helicobacter pylori, which harbors a strong association with gastric cancer and the decreased use of salted and smoked foods.|
|Other risk factors associated with increased incidence of gastric cancers include cigarette smoking, alcohol abuse, and nitrosoamine intake. Benign adenomas, which are the gastric counterpart of colorectal adenomas, are also associated with a risk of progression to cancers. The vast majority (90-95%) of gastric cancers are gland-forming adenocarcinomas. Other less common tumors of the stomach include lymphomas, carcinoids and gastric stromal tumors. Epidemiologic studies have shown that the two major histologic subtypes of gastric adenocarcinomas - the intestinal (well differentiated) type and diffuse (poorly differentiated) type - arise by distinct pathways. The intestinal type is strongly associated with Helicobacter pylori, and usually arises on a backdrop of chronic gastritis, gastric atrophy, and intestinal metaplasia. In contrast, poorly differentiated adenocarcinomas are usually not associated with these changes.Clinically, the latter often present with diffuse thickening of the stomach wall, rather than a discernible mass (linitis plastica). The intestinal adenocarcinomas have a better prognosis than the diffuse variant, most of which have spread beyond the confines of the stomach at the time of diagnosis. As with other cancers, stage is the most important determinant of outcome. In Japan, intensive screening modalities have led to the emergence of a new variant called early gastric cancers, in which the primary tumor is restricted to the mucosa or submucosa, irrespective of metastasis, at the time of detection.|
