In the Kaliningrad region, HPV DNA was detected in 47.2% of the women under study, HPV VR - 31.1%, in 25.5% accompanied by cervix uteri diseases. An increase in the incidence is noted in the Kaliningrad region by 38.6% over 10 years, with an annual increase of 3.8%. In Bashkortostan, the growth is demonstrated by 31.8% with an annual increase of 3%, which is significantly higher than in the Russian Federation (13.3%, р=0.001). For 10 years, the prevalence of cervical cancer has increased in the Kaliningrad region by 10.1%, with an average annual increase of 1.1%. In Bashkortostan, the prevalence of CSM increased by 4.7% with an annual increase of 0.3%.The high prevalence of HPV infection among women of reproductive age, the unfavorable dynamics of indicators of cervical HPV-associated oncopathology in remote regions of the Russian Federation (Bashkiria and the Kaliningrad region) is a scientifically based criterion for the reorganization of regional cervical screening programs. The implementation of Organized screening with primary HPV examination with mandatory separate genotyping of types 16 and 18 and the remaining 12 types of HPV HRC in a complex will enhance the effectiveness of ongoing preventive measures and meet international standards.cancer preventionregional programscervical cancer screeninghuman papillomavirus infectioncervical cancerпрофилактика онкологических заболеванийрегиональные программыскрининг рака шейки маткипапилломавирусная инфекциярак шейки матки1.Состояние онкологической помощи населению России в 2020 году.
