THE PRELIMIRIARY ANALYSIS OF THE RELATIONSHIP BETWEEN MALIGANT TUMOURS AND THE ABO BLOOD GROUPING

Based unon the stetistical analysis of 876 malignaneuas from organis.We found that there were close relationship between cancers of different organs and the distributing patterns of blood ABO grouping.Patients with type A grouping were more susceptable to the development of cancers especially the yastric cancers while the eaecophageal and breast cancers were more commenly seen in patients with type B grouping.The incidence of hepatic cancers was higher in the type A patientsThe ABO biood grouoing of the other 5categories of cancers including the pulmonary cancer showed no significant differences in their distributing patterns,this might be due to the relative small population of sampling,Among the 36cases of leukmias,none of them was in the AB type grouping for which further observations were needed.
