Molecular Basis of Endometriosis and Endometrial Cancer: Current Knowledge and Future Perspectives

The human endometrium is a unique tissue undergoing important changes through the menstrual cycle. Under the exposure of different risk factors in a woman’s lifetime, normal endometrial tissue can give rise to multiple pathologic conditions, including endometriosis and endometrial cancer. Etiology and pathophysiologic changes behind such conditions remain largely unclear. This review summarizes the current knowledge of the pathophysiology of endometriosis and its potential role in the development of endometrial cancer from a molecular perspective. A better understanding of the molecular basis of endometriosis and its role in the development of endometrial pathology will improve the approach to clinical management.

Scoring systems for the evaluation of adnexal masses nature: current knowledge and clinical applications

Adnexal masses are a common finding in women, with 20% of them developing at least one pelvic mass during their lifetime. There are more than 30 different subtypes of adnexal tumours, with multiple different subcategories, and the correct characterisation of the pelvic masses is of paramount importance to guide the correct management. On that basis, different algorithms and scoring systems have been developed to guide the clinical assessment. The first scoring system implemented into the clinical practice was the Risk of Malignancy Index, which combines ultrasound evaluation, menopausal status, and serum CA-125 levels. Today, current guidelines regarding female patients with adnexal masses include the application of International Ovarian Tumours Analysis simple rules, logistic regression model 1 (LR1) and LR2, OVERA, cancer ovarii non-invasive assessment of treating strategy, and assessment of Different Neoplasias in the adnexa. In this scenario, the choice of the scoring system for the discrimination between benign and malignant ovarian tumours can be complex when approaching patients with adnexal masses. This review aims to summarise the available evidence regarding the different scoring systems to provide a complete overview of the topic.

Cervical cancer screening and prevention in Kazakhstan and Central Asia

Objective To examine the state of cervical screening and prevention in Central Asian states, specifically Kazakhstan. Results In the five Central Asian countries that were formerly part of the Soviet Union (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan), cervical cancer incidence and mortality rates are far higher than those in most Western and high-income nations, and are increasing. Cervical cancer screening is available in all five countries, but is mainly opportunistic. Only Kazakhstan has a structured cytological screening program, from which screening coverage analysis is possible. Conclusion Despite significant decreases in cervical cancer incidence and mortality in developed countries, the problem is still of great concern in these Central Asian countries and is attributed to poorly organized screening and the absence of vaccination programs.

Knowledge and awareness of human papillomavirus infection and human papillomavirus vaccine among Kazakhstani women attending gynecological clinics

Cervical cancer remains one of the top causes of cancer-related morbidity and mortality all over the world. Currently, however, there are no published studies to assess the knowledge of HPV and cervical cancer in Kazakhstan. This study aimed to assess the awareness of HPV, the knowledge of HPV as a cause of cervical cancer, and the awareness of HPV vaccination among Kazakhstani women visiting gynecological clinics across the country. In addition, the study aimed to identify the factors associated with the awareness of HPV and the HPV vaccine and knowledge of HPV as a major cause of cervical cancer. This was a cross-sectional survey-based study with 2,272 women aged between 18–70 years attending gynecological clinics, who were administered paper-based questionnaires. Data analysis included descriptive statistics consisting of mean values, standard deviations, and frequencies, where applicable. Differences in categorical variables between groups were analyzed using the Chi-square test with a significance value of <0.005. Crude odds ratio (OR) and adjusted odds ratio (AOR) with 95% corresponding confidence intervals were calculated in regression analysis using univariate and multivariable logistic regression models. The mean age of participants was 36.33±10.09 years. More than half (53%) of the participants had been screened for cervical cancer. Among those who were aware of HPV, 46% knew that HPV causes cervical cancer and 52% were aware of the HPV vaccine. The key factors related to outcome variables were age, ethnicity, education, family, number of deliveries, and menarche. From a subgroup analysis, results from the HPV test and Pap smear test were factors related to dependent variables such as awareness of HPV and awareness of HPV vaccination.

Factors associated with cervical cancer screening behaviour of women attending gynaecological clinics in Kazakhstan: A cross-sectional study

Objective: Although cervical cancer could be prevented through medical screening, it remains one of the top causes of cancer-related morbidity and mortality all over the world. A number of factors may contribute to cervical cancer screening behaviour of women. The aim of this study was to investigate factors related to cervical cancer screening behaviour of women in Kazakhstan. Methods: This was a cross-sectional survey-based study with a total of 1189 participants. Women attending gynaecological clinics aged between 18 and 70 years were administered paper-based questionnaires about their awareness of cervical cancer, the associated risk factors, and cervical cancer screening. Student t test or Wilcoxon rank-sum test and chi-square test or Fisher’s exact test, where appropriate, were used to determine associations with categorical independent variables. Results: The mean age of participants was 36.5 ± 10.1 years. Less than half (45.7%) of the participants had been screened for cervical cancer. The key factors related to the cervical cancer screening behaviour of women in this study included age, having a larger number of children, regular menstrual function, awareness of Pap smear test, and free screening programme for cervical cancer, and the causal association of human papillomavirus with cervical cancer. Conclusion: This study revealed several significant factors predicting screening behaviour in Kazakhstani women. To improve the rate of screening, there is a need to increase public knowledge and awareness of cervical cancer and opportunities for the free screening programme in the female population of Kazakhstan.

Prevalence of high-risk human papillomavirus infection and genotype distribution among Kazakhstani women with abnormal cervical cytology

This study aimed to identify the prevalence and distribution of high-risk human papillomavirus (HR-HPV) types among Kazakhstani women with abnormal cervical cytology. A cross-sectional study was performed from May 2019 to June 2020. Cervical samples were collected from women in the different regions of Kazakhstan. A total of 316 patients' samples were analysed for HR-HPV using real-time multiplex PCR. Cervical cytology abnormalities were reported according to the Bethesda classification. HPV detection by cytology showed a statistically significant association with HPV status and the number of HPV infection types ( There is a high prevalence of HR-HPV types among Kazakhstani women with abnormal cervical cytology. The most identified types were HPV16, 18, 31, 33 and 52. There is an emergency need to implement an HPV vaccination program to prevent cervical lesion development.

Patient acceptance of HPV self-sampling approach for cervical cancer screening: evidence from a pilot study in Kazakhstan

Cervical cancer remains a major global health burden, particularly in low- and middle-income countries. In Kazakhstan, cervical cancer incidence is rising, despite an established cytology-based screening program. Self-sampling for human papillomavirus (HPV) genotyping is suggested as a promising strategy to improve screening participation, yet it has not been evaluated in Kazakhstan. Thus, this study aims to perform a preliminary assessment of self-sampling approach acceptance among Kazakhstani women. A cross-sectional study was conducted among women attending outpatient clinics in large cities in Kazakhstan between August 2024 and June 2025. Participants used both the Evalyn Brush and BGI Sentis self-sampling kits and completed structured questionnaires assessing knowledge, perceptions, ease of use, discomfort, confidence and willingness to recommend. Descriptive and bivariate statistics were performed to evaluate associations with acceptance and usability. A total of 124 women were included in this pilot study, with a median age of 34.5 years (IQR: 27.5-44.0). Only 28.2% of respondents preferred self-sampling for their next screening, whereas 62.1% preferred gynaecologist-collected samples. The Evalyn Brush demonstrated higher ease of use (93.5%) compared to the BGI kit (45.2%). Confidence in correct self-collection was also higher for the Evalyn Brush (85.4% vs. 67.7%). Women who believed that home-based self-sampling is easier than Pap-smear were significantly more likely to prefer self-sampling for future screening ( Self-sampling is acceptable for a proportion of Kazakhstani women, with the Evalyn Brush showing greater comfort, ease and confidence, indicating that device selection is critical for successful implementation. The findings support further large-scale evaluation that will guide improvements to Kazakhstan's cervical cancer screening programme. A nationwide study is required for a more precise assessment of the self-sampling approach acceptance and the strategy's feasibility.
