Abstract
Description
Se comparó la incidencia de labaéteria Hdicobacter pylori en un lugar pe baja incidencia de cáncer gástrico, Poás ( 15. 13%) y otro de incidencia muy alta, Puriscal (83. 53%) Se eligió a 185 adultos de cada cantón, similares en edad y sexo y se practicó un estudio serológico para buscar anticuerpos IgG para H. pylori, y una gastroscopía para tomar dos biopsias por caso. Los resultados no apoyan la existencia de una fuerte relación entre H. pylori y cáncer gástrico
Occurrence of the bacterium Helicobacter pylori was compared for two Costa Rican sites with contrasting levels of gastric cancer incidence, Poás (incidence 15. 13%) and Puriscal (83. 53%). A sample of 1 85 adults of similar age and sex proportions was studied in each site, using both H. pylori antiserum tests and gastroscopy to collect two biopsies per case. No c1ear association between H. pylori and gastric cancer was found.
