Prevalencia de Helicobacter pylori en pacientes con cáncer gástrico en SOLCA-Loja durante el período enero 2013 diciembre 2014

Abstract

Abstract:Since the Helicobacter pylori bacterium was discovered and isolated in gastric tissue by Marshall and Warrent in 1983, our knowledge about this bacterium and its pathogenesis has grown dramatically. In 1994, the bacterium was classified as a gastric carcinogen in humans. In this work, a descriptive, retrospective, cross-sectional and observational study was conducted, in which the medical records of patients diagnosed with gastric cancer in SOLCA nucleus Loja, January 2013-December 2014 period, were reviewed. A sample of 34 cases was used, where it was shown that the prevalence of H. pylori infection was 38.24 per 100 people. The predominant sex is male (59%) and is more frequent between 70-79 years (24%). The most frequent stage of gastric cancer at diagnosis was IV (50%). The greatest histological variety was intestinal adenocarcinoma (56%). It is concluded that since Loja is an endemic area of ​​gastric cancer and there are high rates of H. pylori infection in Ecuador, the bacterium is considered as an important risk factor for the development of gastric cancer.
