Sulle Associazioni Fenotipiche Dei Gruppi Sanguigni ABO Con Il Cancro Gastrico E L'Ulcera Gastrica E Duodenale

The association of groups ABO with gastric cancer (1333 cases), gastric ulcer (343 cases) and duodenal ulcer (740 cases) has been studied.No correlation has been observed between gastric cancer and blood groups, whereas an heterogenic distribution of blood groups in relation to tumor site could be noted: e. g., group A was found to be associated to antral cancer, and group O to the cancer of the body and of the fundus.A highly significant heterogeneity of distribution of the groups ABO in the different ages was observed in patients bearing gastric ulcer.The correlation between duodenal ulcer and group O has been confirmed. The relative disease incidence for the subjects belonging to this group was demonstrated to be 55 per cent higher than that of group A subjects.No sex influence on groups ABO distribution was observed in the three studied conditions.
