Examining the presence of ABO(H) antigens of blood types in the saliva of patients with oral cancer

Abstract

Number of researches dealing with the influence of the ABO blood group antigens on the development of the oral cancer have hypothesized that people who do not secrete these substances in the saliva are more prone to suffer from this disease. The objective of this research is to examine this hypothesis. In total 114 subjects were examined, half of which suffered from oral cancer, while the other half was the healthy control group. All examinees were subjected to clinical examinations and the experimental group to pathohistological examination. An analysis of the secretor status was carried out using the Wiener agglutination test. The experimental group consisted of 78.95% of secretors, while the control group consisted of 82.46% of secretors. This difference is not statistically significant. The starting hypothesis that non-secretors are more prone to the development of oral cancer was not confirmed.
