ABSTRACT

RESUMEN La Organización Mundial de la Salud señala que el cáncer gástrico es una neoplasia frecuente en el mundo contemporáneo. Constituye la segunda causa de muerte en el hombre y la tercera en las mujeres. Numerosos son los factores de riesgo que se asocian con la aparición del cáncer gástrico, en determinadas regiones del mundo. El descubrimiento del Helicobacter pylori y la asociación con las enfermedades gastroduodenales ha revolucionado los aspectos fisiopatológicos y terapéuticos hasta el punto de considerar la bacteria como agente precursor del cáncer gástrico. Por tal motivo se realizó una revisión de los factores de riesgo y el papel del Helicobacter pylori en la formación de la neoplasia gástrica, con el objetivo de aportar conocimientos relacionados con el cáncer gástrico y su prevención (AU).

There are several risk factors associated to the development of gastric cancer in specific regions of the world. The discovery of Helicobacter pylori and its association to gastro duodenal diseases has renewed the physiopathological and therapeutic aspects up to the point of considering the bacteria as precursor agent of gastric cancer. For that cause, it was carried out a review of the risk factors and the role of Helicobacter pylori in the formation of gastric neoplasia, with the objective of giving out knowledge related to gastric cancer and its prevention (AU).
