Prevalence of H. Pylori in Stomach Cancers in the West Indies

Stomach cancer is the 4th most common cancer site in the world and the 3rd cause of mortality. It is associated with infection by the Helicobacter Pylori bacterium, which colonizes the gastric mucosa in 80% of cases. The decrease of the prevalence of H. pylori infection in developed countries with the advent of antibiotic treatments is responsible for the decrease in the incidence of stomach cancer. But in the French West Indies, stomach cancer remains in excess incidence and mortality compared to France. The prevalence of H. pylori infection remains unknown, both in general population and in patients with stomach cancer. Eating habits combining high consumption of salt, meat and smoked fish could partly explain these high incidences. Furthermore, recent observations suggest that environmental risk factors (pesticides pollution) could also be involved in the occurrence of this cancer. Estimating the prevalence of H. pylori in stomach cancers will improve the epidemiological knowledge of this cancer with high incidence rates and prevention measures.
