CARCINOMA GLANDULAE PAROTIS AND BLOOD GROUP AFFILIATION

Abstract

The current study included 83 patients with Ca glandulae parotis (72 men and 11 women) whose blood group affiliation to the AB0 and Rhesus factor systems was monitored. A comparison was made with a control group of healthy individuals from the modern Bulgarian population. The distribution of the blood groups in the sample was different from that of the control group (p <0.001). There was a significant increase in the prevalence of persons with blood group B (p <0.001), and a significant decrease in groups 0 (p <0.001) and A (p <0.05). In group AB, a slight increase in frequency was detected. With respect to the Rhesus factor, there was an increase in the patients with positive Rhesus factor - by 9.23% to 93.94% (p<0.05). It can be assumed that, among other risk factors, belonging to group B and having a positive Rhesus factor are one of the reasons for the appearance and development of the disease.
