Cervical cancer screening: Twelve years experience of the Kazakhstan National Screening program.

Abstract

e17520 Background: Cervical cancer (CC) is the most common gynecological cancer in Kazakhstan (KZ). Standardized incidence rate of CC was 16.7 per 100, 000, while the mortality rate was 5, 9 per 100, 000, in 2020. The National Cervical Screening program in KZ uses cytology (Pap test) from 2008, which is free of charge for women aged 30 to 70 years of age with an interval of 4 years. In 2017 Experts from ImPact Mission and analyzed existing CC screening revealed a number of recommendations aimed at reducing the screening interval and increasing the coverage. The purpose of this study was to analyze results of CC screening in KZ and his impact on CC incidence and mortality. Methods: Coverage, the number of screened women, the level of pre-cancer detection and cervical cancer during screening have been obtained from specific reports (form № 025, № 08) for 2008-2020. Results: The total number of screened women for 2008 were 554 283 women. There is a decrease in screening coverage to 45.9% in 2017 due to a decrease in funding. in this regard, in 2017, a number of changes were made to the existing screening program. In 2020 after the CC screening improvement 786 690 women were examined during the screening program, coverage rate was 66, 2%, . Analysis of screening results showed a marked increase in the detection of precancerous lesion from 0, 136 in 2008 to 0, 87 with an increasing by 37%. The analysis of CC incidence revealed significant changes: after the introduction of screening, an increase in the incidence rate is noted from 15.5 in 2008 to 20.1 per 100, 000 female population in 2015. Since 2015, there has been a significant decrease to 16.7 per 100, 000 women. Conclusions: Despite the positive results of screening, an increse the screening coverage, improvement in the detection of the initial stage of CC, mortality rate from CC and a one-year mortality remain high, which makes it necessary to improve the screening of CC in KZ through the introduction of HPV-screening
