The incidence of human papillomavirus (HPV) -associated oropharyngeal tumors is steadily increasing therefore, information about the prevalence of oral HPV and its risk factors is very important for future screening and early diagnosis of the disease. This thesis addresses three topics. The first topic is to evaluate the prevalence of oral HPV in a healthy population and to investigate risk factors for oral HPV infection, given that these data are almost completely absent in Central Europe. A statistically significantly higher rate of positivity (8.8%) of oral HPV infection was found in the group of older unvaccinated probands than in younger partially vaccinated volunteers (2.0%). The seropositivity rate of anamnestic HPV antibodies was comparable in both groups. None of the analyzed risk factors were significantly associated with oral HPV positivity. The second topic of the thesis is the dynamics of HPV specific antibodies in patients with head and neck cancer and their prognostic significance. In patients with cervical cancer, a decrease in HPV E6 / E7-specific antibodies is associated with a better prognosis. Another goal of the dissertation was to assess the importance of anamnestic antibodies and antibodies against oncoproteins E6 and E7 in long-term follow-up 2-14 years after the end of...
