title: [Genetic analysis of the gastric precancer-cancer system. I. Research in different populations].
abstract: Heredity predisposition was analysed in cancer and precancer stomach diseases in distinct populations. Some phenotypic and genetic characters of the stomach "precancer--cancer" system were studied. Similarity in the degree of stomach cancer inheritance, its segregation frequency and recurrent risk was revealed for populations. However, the degree of correlation between cancer and precancer stomach disease was different in distinct populations, this being more pronounced in "cancer--gastric ulcer" system.
