Duration of exposure a neglected factor in chemoprevention trials. It is the histological type that predominates in high risk areas of gastric cancer and the type associated with the global decrease in gastric cancer incidence. Gastric cancer in Colombia. Two main types of intestinal metaplasia are recognized: The average age of the patients in whom the regression of metaplasia was observed was There is a variety of environmental, infectious, and host-related factors that may interact favoring the development of the disease.

Prevalence and severity of gastric cancer precursor lesions in a high risk area

In the initial pre-cancerous lesion, atrophic gastritis is characterized by the death of the parietal cells and the loss of the glandular epithelium that covers the mucosa of the stomach 4. Scand J Surg ; A study of asymptomatic children under 10 years old from Pasto published by Bedoya A. The study was also demonstrated that the higher the bacterial load the greater the patient’s compromise due to histological damage Figure 8.

We want to especially recognize the late Dr.

I polypoid, II ulcerated with well-defined borders, III ulcerated with irregular and infiltrative borders, and IV diffuse infiltrative, with no evidence of mass or ulcer gastrifo In order to unify the histopathological evaluation of atrophic gastric lesions an international group of pathologists proposed a system Operative Link for Gastritis Assessment, OLGA based enn stages associated with cancer risk 0-IV Latin-American countries have among the highest rates of H.

Sug Pathol ; The statistical analysis was conducted using the Fisher’s exact test and the McNemar’s test. In general, gastric cancer rates are twice as high in men as in women. Host factors Genetic polymorphisms.

Helicobacter pylori colonizes the gastric mucosa of humans early in life establishing long-lasting naio inflammation of the mucosa, the driving force for the fn of pre-neoplastic lesions [ 56 ]. We base this conviction on the fact that the majority of intestinal gastric cancer takes roots in premalignant lesions, the belief that by contributing to the knowledge of all the professionals involved with this pathology we can bring clarity to the treatment of risk factors.

It consists of a high mountainous Andean region which has a high incidence of gastric cancer and a low coastal region which has a low incidence of gastric cancer. We present annual age and sex standardized rates, primarily as mortality rates in South America and incidence rates in Central America, based upon available sources. gastric

Etiology Gastric cancer is a multifactorial disease. Genetic factors related to gastric cancer susceptibility identified using a genome-wide association study. Atrophy and intestinal metaplasia are persistent lesions irrespective of Helicobacter pylori infection. The most important environmental factor related to the development of gastric intestinal metaplasia is H. Based on the study of gene sequences, a growing variety of phylogenetic groups and subgroups of H.


The soil of volcanic regions and gastruco altitude areas usually contain low amounts of selenium, as compared with soil in valleys or coastal regions. Rev Cubana Med ; The elimination criteria included patients who had not been monitored for a year, patients for whom the presence of H.

Infection with babA2 -positive strains is associated with increased risk of gastric adenocarcinoma een Gastric cancer is one of the most common malignant diseases with one of the highest mortality rates worldwide. Both species Homo sapiens and H. The authors acknowledge the valuable collaboration of the research team in Colombia that makes the realization of our studies possible.

The updated sydney system. In our study we found large colonies of Helicobacter pylori in the gastric corpus with the moderate to severe bacterial loads associated with chronic atrophic gastritis and intestinal metaplasia. If the patient is under 40 years old, endoscopic checkups every 3 years are recommended.

A large number of these professionals do not have clear or profound knowledge of the risks, natural history, possible interventions and monitoring required when faced with a pathological report of chronic atrophic gastritis with or without intestinal metaplasia. Rev Costarric Salud Publica. Nutrition and gastric cancer. The publisher’s final edited version of this article is available at Cancer Causes Control. The clustering of multiple factors may differ among the mountainous regions in the Americas.
