Abstract
- Introduction: Gastric cancer is one of the top causes of cancer-related death worldwide. How to eliminate gastric cancer is an urgent public-health issue. Areas covered: In this review, we present up-to-date results of studies on gastric cancer prevention through the eradication of Helicobacter pylori and discuss strategies and obstacles for the implementation of population-wide screening and treatment of this pathogen to prevent gastric cancer. Expert commentary: Gastric cancer is an inflammation-associated cancer with multistep carcinogenesis. The process consists of H. pylori infection, ongoing inflammation, development of metaplastic epithelia and genetic instability eventuating in gastric cancer. H. pylori infection is critical for development of the disease and studies have consistently shown that H. pylori eradication results in a reduction in (a) gastric mucosal inflammation, (b) progression of histologic damage, (c) risk of peptic ulcers and ulcer recurrence, and (d) risk of gastric cancer. Compared with a large number of clinical trials evaluating chemopreventive approaches, studies of population-wide screening, and eradication of H. pylori have only recently begun and only in high-risk populations. To eliminate gastric cancer requires information on how to implement an effective program for screening and treatment of H. pylori taking into consideration the other health priorities in any specific population.
