title: [The role of genetic factors in the development of gastric cancer].
abstract: In general, a genetic predisposition to a tumour disease such as gastric cancer is postulated in patients with cancer at an unusually early age or when several relatives are affected. A clear definition of hereditary gastric cancer is lacking. Two types of families may be distinguished: kindreds with gastric cancer only (site-specific), and kindreds with gastric as well as colorectal cancer, representing the hereditary non-polyposis colon cancer (HNPCC) syndrome. A genetic predisposition is presumed in young patients with a diffuse type of gastric cancer, in contrast to the intestinal type which is associated with atrophic gastritis and older age. A variety of genetic abnormalities in tumour tissue have been described, e.g. mutations in genes involved in DNA repair. Helicobacter pylori plays an important role in the aetiology, but the interaction with genetic factors is unknown.
