At the present time, cervical cancer remains the fourth most prevalent cancer among women worldwide. Most cervical cancer cases are attributed to high-risk human papillomavirus (HPV) infection. Because the natural history of cervical cancer takes decades, the disease could be prevented if premalignant conditions are identified and appropriately managed. The aim of this study is to identify the prevalence of precancerous lesions among non-vaccinated women attending the national tertiary care hospital in Kazakhstan. This was a retrospective study of the cervical cancer screening database (2018) from the national tertiary care hospital in Kazakhstan. Records of 6682 patients, who had cervical cytology tests by Papanicolaou (Pap test), were analyzed. Out of the revised cases, 249 patients had abnormal cervical cytology reports. The Pap test was performed using liquid-based cytology (LBC). The data were analyzed using the statistical software STATA 16. A -value of less than 0.05 was considered statistically significant. In this retrospective analysis of 6682 patients' records, we found 3.73% (249 patients) out of all Pap tests performed in 2018 were abnormal. The prevalence of high-grade squamous intraepithelial lesion (HSIL) was high at 19.28%, and the proportion of atypical squamous cells of undetermined significance (ASCUS) and atypical squamous cells (ASCs-H) was 18.47%, while low-grade squamous intraepithelial lesion (LSIL) were identified in 62.25% of the cases. Almost 25% of the women included in the study had concurrent lower and upper genital tract infections. Although the overall rate of abnormal Pap test results was not high, the study shows the elevated prevalence of HSIL. It calls the attention of local policymakers and gynecology specialists and requires immediate actions to improve the prophylactic measures to decrease morbidity and mortality from cervical cancer in Kazakhstan.
