Résumé
Le cancer gastrique est observé partout dans le monde. Sa fréquence est particulièrement élevée au Japon et en Amérique du Sud. Son incidence n’a cessé de décroître en France depuis la fin de la Seconde Guerre mondiale et, actuellement, ce cancer n’est responsable que d’environ 10 % des décès. L’infection par Helicobacter pylori, la spécificité génétique et le régime alimentaire de l’hôte sont les principaux facteurs impliqués dans ce cancer. Éradiquer Helicobacter pylori chez les apparentés au premier degré d’un sujet atteint de cancer gastrique et chez tout sujet ayant une gastrite atrophiante et un autre cancer digestif paraît une mesure préventive sage.
Summary
Gastric cancer is a worldwide cancer especially frequent in Japan and South America. This cancer affects 10 to 70 people per 100 000 according to the countries. Since the end of the Second World War, the incidence of gastric cancer has been decreasing in France and accounts for less than 10 % of mortality. Helicobacter pylori infection, host genetic background, food regimen are known to be involved in this cancer. Helicobacter pylori should be eradicated in selected patients, such as patients’ relatives with documented gastric cancer as well as patients having another gastrointestinal cancer.
