Introduction:Human papillomavirus (HPV) infection represents the most important risk factor for the development of cervical intraepithelial neoplasia (CIN) and cervical cancer. We aimed to analyze the consequences of methylation of the E6 gene promoter in distinct stages of HPV-16-induced cellular transformation to assess its importance for disease progression.Methods:Human papillomavirus 16 was detected by sensitive polymerase chain reaction (PCR). Determination of E6 gene promoter methylation was analyzed by digestion with specific restriction endonuclease McrBC followed by PCR amplification. Expression of the E6 gene was determined by quantitative real-time PCR.Results:Of 103 cervical smears from asymptomatic women with no cytological and colposcopic abnormalities, 20.4% were HPV-16-positive. Human papillomavirus 16 was present in 44.4% of 18 patients with CIN I, in 62.2% of 143 patients with CIN II/III, and in 74.2% of 31 cervix carcinoma specimens. The incidence of HPV-16 in all lesions compared with asymptomatic women was statistically significant (P< 0.001, Pearsonχ2test). Methylation was detected in 81% (n = 21) of HPV-16-positive asymptomatic smears compared with 62.5% in CIN I (n = 8), 31.5% (n = 89) in CIN II/III, and 43.4% (n = 23) in carcinomas; a statistical significance between lesions and healthy women was found (P< 0.001, Pearsonχ2test). Expression of E6 mRNA correlated with methylation status (P= 0.010, Mann-WhitneyUtest).Conclusions:We conclude that methylation of the E6 gene promoter in HPV-16 genome is a predictive biomarker for cervical cancer progression by regulating the expression of the E6 oncogene.

Aim. Conduct a comparative assessment of the main indicators of the incidence of cervical cancer in Khabarovsk Krai (20092019) аnd the prevalence of types of human papillomavirus among the female population. Materials and methods. A comparative analysis of the data of the official statistics of the Ministry of Health of Khabarovsk Krai, using the Rosstat database for the period 20092019, taking into account the incidence, mortality, prevalence of types of human papillomavirus, was carried out. The dynamics trend was determined in the process of graphical analysis of the diagram and by modeling trends. The results of the studies were subjected to the methods of statistical information processing. Results. The results revealed in our study indicate that the increase in the incidence of cervical cancer in Khabarovsk Krai from 2009 to 2019 was 44.4% (with an average annual growth rate of 4.5%). Most often, cervical cancer in Khabarovsk Krai is detected in urban residents. The share of urban women with this pathology in 2019 reached 77.2%. The proportion of stage III cancer detected exceeds the proportion of stage IIIIV cancer by 2.5 times. Mortality in patients with cervical cancer in Khabarovsk Krai exceeds that in the Russian Federation. Of the 1617 residents of the city of Khabarovsk of reproductive age, 883 (54%) women had the presence of human papillomavirus. For our region, most often, women had highly oncogenic types of human papillomavirus 16, 56, 51. Conclusion. Statistical analysis based on the results of diagnosing early and advanced stages of cervical cancer, mortality from this nosological form, and the spread of the human papillomavirus remain among the most important criteria. The data obtained make it possible to assess the effectiveness of the chosen tactics in the regions and take timely corrective measures aimed at both early detection of cervical cancer and a decrease in the persistence of the human papillomavirus in women with background cervical pathology.
