How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

e18020 Background: Cervical cancer is the second most common cancer in women worldwide, where the majority of registered patients are in developing countries. Screening programs in developed countries have reduced morbidity and mortality from cervical cancer by more than 2 times. Cervical cancer (CC) is the most common gynecological cancer in Kazakhstan (KZ). Standardized incidence rate of CC was 18.2 per 100,000, while the mortality rate was 6.2 per 100,000, in 2019. The National Cervical Screening program in KZ uses cytology (Pap test) from 2008. Screening program funded by the State budget. In 2016, Experts of imPACT Mission analyzed the CC screening and made recommendations for improvement. Since 2018 target age of CC screening expanded to 30-70 years and shortened the interval to 4 years, strengthened the control of patients with pre-cancerous pathology. Until 2018, people came to a fixed age; today we start CC screening within the target age at any age at the time of the first visit. The purpose of this study is to analyze cytological screening results in KZ after imPACT recommendations. 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 2008-2019. Results: The total number of screened women was in 6.775.975. There is a decrease in the number of screened women by 32% from 2008 to 2017. Since improvement of CC screening we increased coverage from 49.9% in 2017 (abs. number 409.124) to 89% in 2019 (abs. number 954.322). According to the results of screening, 2603 cases of CC were registered in 12 years. Analysis of screening results showed a marked increase in the detection of CC with an increasing by 67%. The persentage of registered cases of ASH+HSIL increased from 0.136% to 0.673%. Conclusions: there has been an increase in the coverage by screening of the target population since the screening update. During the study period, there has been an improvement in the detection of precancerous pathology and cancer in the early stage. Despite the positive results of screening, sufficient coverage by screening, certain successes in detecting the initial stage of CC, mortality rate from CC remain high, which makes it necessary to improve the screening of CC in KZ through the introduction of HPV-screening.
