Update on the risk factors associated with gastric cancer mortality

Abstract

Introduction: Gastric cancer is the second cause of death in the world population. It ranks eighth in Cuba. The etiology is multifactorial. Helicobacter pylori infection, diet, genetic susceptibility, and family history are some of its risk factors. Objective: To update the aspects related to risk factors involved in gastric cancer mortality. Material and Methods: A systematic review was carried out through the search of articles published until October 2020 that provide information about risk factors associated with gastric cancer mortality. Results: A total of 31 articles were included; the most studied risk factor was H. pylori infection, which plays an important role in the carcinogenesis of gastric cancer; the factors most frequently associated with mortality from gastric cancer are age, sex, diet, and family history. Conclusions: There is a high heterogeneity among the risk factors studied. The identification of associated risk factors can be the axis for the prevention and control of this disease.
