RESUMO
Objective: to detect the HPV types distribution both in general female population and in women with first diagnosed cervical cancer, including viral load in both groups. Methods: Qualitative detection and quantification of HPV was performed by PCR-Real time method based on the Russian equipment and test systems ("DNA-Technology" LLC, Russia). The DNA of low-risk (HPV 6, 11, 44) and possibly / potentially / high carcinogenic risk (HPV 16, 18, 26, 31, 33 , 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 73, 82), a total of 21 types, were detected. Results: During the period of 2014-2017 total 1,166 clinically healthy women were tested for HPV, as well as 73 women diagnosed with CaCx. Overall prevalence of HPV in female population was determined as 25.0% (95% CI 22.3;27.7, p = 0.05). Top-5 leading HPV types: 16 (26.4%); 31 (10.1%); 51 (9.4%); 52 (9.0%); 6 (7.9%). Average viral load was 5.5±3.8 (CI 95% 5.1;5.9). In women diagnosed with CaCx ranking was as follows 16 (54.1%), 31 (11.2%), 18 / 58 (5.1% each), 33 / 45 (4.1% each). Type 16 appeared to be one of the most significant risk factors of the CaCx development (p=0.00007, phi 0.35, Pierson's X 2 15.9). Average viral load in patients with CaCx was 6.9±4.0 (95% CI 6.1;7.7). A reliable relationship between the cancer staging and the viral load was found (p = 0.043, n = 73). Domination of type 16 calls for urgent need the transition to HPV primary screening and resumption of immunization program discontinued in 2014. The study is registered in ISRCTN registry, No. ISRCTN71514910 (01.02.2018).
