Core Tip
Core tip: This article is a review about the current state of art of studies carried out in Latin America using gene polymorphisms to assess gastric cancer susceptibility. Latin America shows one of the highest incidence rates of gastric cancer in the world, with variations in mortality rates among nations or even within countries belonging to this region. Moreover, Latin America is a region with a particular genetic background, high rates of Helicobacter pylori infection and lifestyles condition. This review also gives special emphasis on the importance of the studies conducted in gastric precancerous diseases.
