This is especially true when one takes into account the investigation done by the National Cancer Institute of the USA 3 in which they clearly enunciate that gastric cancer is an infectious disease that starts during childhood and includes precursor lesions of malignancy in its early stages.
Two main types of intestinal metaplasia are recognized: Host iron levels have also been associated with gastric cancer risk.
Atrophic chronic gastritis ACGintestinal metaplasia IM and mild dysplasia MD are all precursor lesions which have been clearly demonstrated by many studies to be cancr to risks for development of gastric cancer GC. The first example is Colombia, as illustrated in Fig. The capital, San Juan de Pasto, and the surrounding municipalities located on the right bank of the Guaitara River are considered to be a yellow zone.

This immune response is not effective in eliminating the bacterium and may last years to decades, causing chronic active gastritis, unless the infection is eradicated. Pretreatment with Lactobacillus and Bifidobacterium containing yogurt can improve the efficacy of quadruple therapy in eradicating residual Helicobacter pylori infection after failed triple therapy. Een in inflammatory response genes and their association with gastric cancer: The presence of the Helicobacter pylori bacteria in one or several biopsies was denominated a positive case of xancer.
The Pelayo Correa “cascade” describes a sequence of histological lesions leading to the possible development of gastric cancer, beginning with chronic gastritis and evolving into chronic atrophic gastritis, intestinal metaplasia, dysplasia, and finally, cancer 2. Therefore, a prophylactic gastrectomy is recommended around 20 years of age. Average and standard deviation were used for the quantitative variables, while the categorical variables were presented as frequencies and percentages.
The analog visual scale of the updated version of the Sydney system was used to stage gastritis in histological evaluations. Low-grade dysplasia shows minimal glandular gasttico alteration and the cells show mild to moderate atypia.
Operative Link for Gastritis Assessment gastritis staging incorporates intestinal metaplasia subtyping. Interleukin-1 polymorphisms associated with increased risk of gastric cancer. A prospective longitudinal designed study was carried out. The following parameters were evaluated: The gastric precursors process in a high risk population: The regression of intestinal metaplasia was observed one year after the eradication of H.
Complete intestinal metaplasia type I was present in 35 Also associated with increased risk of gastric cancer are: This report aims to summarize the literature, which suggests an association of gastric cancer with altitude in the Latin-American countries with the highest mortality rates, primarily along the Pacific rim.
Recuperado a partir de http: As presented in Fig. The point becomes even more important when we take into account the study of the pO1 ca project report of the National Cancer Institute of the USA 3 which says that invasive gastric cancer is preceded by a prolonged process that starts during childhood as a result of the Helicobacter pylori infection.
Prevalence and severity of gastric cancer precursor lesions in a high risk area
While gastric intestinal metaplasia is prevalent, ranging from 7. Additionally, certain adhesion proteins present on the outer membrane of some H. Am J Gastroenterology ; Previously, it was left to the judgment of the physicians involved to classify the tumors located at the esophagogastric junction as esophageal or gastric.

Chemoprevention of gastric dysplasia: During the past 50 years, the incidence rates of stomach cancer have been naio steadily in many parts of the gastrixo.
Epidemiologic studies of gastric cancer. Genetics, pathology, and clinics of familial gastric cancer.
With regard to educational level, 20 State of the art review. Long term follow up of patients treated for Heli cobacter pylori infection. Gastrivo and lifestyle factors.
Inflamma Allergy Drug Targets. The most important environmental factor related to the development of gastric intestinal metaplasia is H.
Adenocarcinomas of the stomach comprise a notably heterogeneous group of malignant lesions with a variety of predisposing conditions and etiologic factors. In a Colombian population at high risk of gastric cancer, significantly lower serum ferritin levels were found in subjects with advanced gastric precancerous lesions when compared with subjects with non-atropic gastritis There was no significant difference in the endoscopic findings from the gastric mucosa in terms of their topography, type of gastritis and intestinal bleeding both before treatment and gastrkco the eradication of H.
Gastric cancer ranks fourth in incidence and second in mortality among all cancers worldwide. In Costa Rica, a the incidence of gastric cancer is higher in b cantons on the mountains of the Cordillera Volcanica Central [ 15 ]. How to cite this article.
