Lifetime Prevalence of Cervical Cancer Screening in 55 Low- and Middle-Income Countries

Barriers and facilitators for implementation of HPV-based cervical cancer screening in Tanzania: a qualitative study among healthcare providers, stakeholders, and Tanzanian women

BACKGROUND

Cervical cancer is the leading cause of cancer-related deaths in Tanzania and the most common form of cancer among Tanzanian women. Screening attendance remains among the lowest globally, necessitating improved attendance and screening methods.

OBJECTIVE

This study aims to assess the feasibility of implementing the World Health Organization's 2021 hPV-based screening guideline in Tanzania by identifying potential barriers and facilitators to HPV-based screening among screening clients, healthcare providers, and stakeholders.

METHODS

From October 2022 to February 2023, 25 semi-structured interviews were conducted with screening clients (n = 16) and healthcare providers and stakeholders (n = 9) in Moshi and Dar es Salaam. Data were analyzed using a deductive framework based on Bronfenbrenner's Social Ecological Model, supplemented with inductive subcategories from the transcripts.

RESULTS

Barriers and facilitators emerged across all levels of the Social Ecological Model. At the individual level, clinic-based screening and a one-visit approach were barriers, while HPV-self-sampling was a facilitator. Interpersonal barriers included limited social support, while referrals served as facilitators. Community-level barriers included fear and misconceptions, countered by facilitators such as increased awareness and health education. Health system challenges included restrictive age limits and urbanization of human resources, with uptake through other health services acted as a facilitator. Political barriers highlighted the need for a steady local supply chain, while cost reduction could serve as a facilitator for guideline implementation.

CONCLUSION

WHO's 2021 hPV-based screening guideline shows promise in Tanzania, but barriers such as clinic availability, fear, misconceptions, and supply chain issues must be addressed to ensure successful implementation.

Effect of girls' education on cancer awareness and screening in a natural experiment in Lesotho

Breast and cervical cancers are important causes of disability and premature death among women in Sub-Saharan Africa. Previous research has linked girls' education to cancer service access. Here, we examine the causal effect of girls' educational attainment on cancer screening practices by means of a natural experiment in Lesotho. In particular, we exploit variation in educational attainment among women that was introduced by an educational policy (a school-entry age cut-off). Data on awareness towards breast cancer, knowledge of Pap smear, breast self-exam, breast clinical exam, and having received a Pap smear is extracted from the Lesotho Demographic and Health Surveys 2009-10 and 2014 (N = 7971). Each additional year of schooling caused by the education policy increases awareness of breast cancer by 4.7 percentage points (p = 0.014, 95% Confidence Interval [CI]: 1.0, 8.5), awareness of Pap smear by 5.9 percentage points (p = 0.001, 95% CI: 2.3, 9.5), and engagement in Pap smear by 3.5 percentage points (p = 0.004, 95% CI: 1.1, 5.8). We found no statistically significant effects on breast self-exam and breast clinical exam.

CausalCervixNet: convolutional neural networks with causal insight (CICNN) in cervical cancer cell classification-leveraging deep learning models for enhanced diagnostic accuracy

Cervical cancer is a significant global health issue affecting women worldwide, necessitating prompt detection and effective management. According to the World Health Organization (WHO), approximately 660,000 new cases of cervical cancer and 350,000 deaths were reported globally in 2022, with the majority occurring in low- and middle-income countries. These figures emphasize the critical need for effective prevention, early detection, and diagnostic strategies. Recent advancements in machine learning (ML) and deep learning (DL) have greatly enhanced the accuracy of cervical cancer cell classification and diagnosis in manual screening. However, traditional predictive approaches often lack interpretability, which is critical for building explainable AI systems in medicine. Integrating causal reasoning, causal inference, and causal discovery into diagnostic frameworks addresses these challenges by uncovering latent causal relationships rather than relying solely on observational correlations. This ensures greater consistency, comprehensibility, and transparency in medical decision-making. This study introduces CausalCervixNet, a Convolutional Neural Network with Causal Insight (CICNN) tailored for cervical cancer cell classification. By leveraging causality-based methodologies, CausalCervixNet uncovers hidden causal factors in cervical cell images, enhancing both diagnostic accuracy and efficiency. The approach was validated on three datasets: SIPaKMeD, Herlev, and our self-collected ShUCSEIT (Shiraz University-Computer Science, Engineering, and Information Technology) dataset, containing detailed cervical cell cytopathology images. The proposed framework achieved classification accuracies of 99.14%, 97.31%, and 99.09% on the SIPaKMeD, Herlev, and ShUCSEIT datasets, respectively. These results highlight the importance of integrating causal discovery, causal reasoning, and causal inference into diagnostic workflows. By merging causal perspectives with advanced DL models, this research offers an interpretable, reliable, and efficient framework for cervical cancer diagnosis, contributing to improved patient outcomes and advancements in cervical cancer treatment.

RING box protein-1 promotes the metastasis of cervical cancer through regulating matrix metalloproteinases via PI3K/AKT signaling pathway

Cervical cancer (CC) remains a leading cause of cancer mortality amongst females worldwide. Some of the CC patients may experience early metastases of the primary tumor, however the underlying mechanism remains unclear. Aberrant expression of RING box protein-1 (RBX1), a subunit in the E3 ubiquitin ligase family, has been reported in several cancer types. Nevertheless, little is known regarding the role of RBX1 in the metastasis of CC patients. In this study, we examined the expression of RBX1 from 90 biopsies of CC patients, and found a significantly increased expression of RBX1 in the tumor tissues compared to the normal tissues. Notably, the abundance of RBX1 in the CC patients with metastasis was higher than their counterparts without metastasis, suggesting that RBX1 may play a significant role in the modulation of CC metastasis. Furthermore, by using Hela cells as a model of CC in vitro, we demonstrated that ectopic over-expression of RBX1 could significantly promote the migration and invasion of Hela cells, whereas knockdown of RBX1 could remarkably suppress the migration and invasion of Hela cells. Mechanistically, the regulatory effect of RBX1 on cell metastasis was associated with changes in matrix metalloproteinases (MMP3 and MMP9) and altered activity of PI3K/AKT signaling. In conclusion, this study highlighted RBX1 as a novel target that can promote the metastasis of Hela cells in vitro, which may contribute to the development of alternative therapeutic options for CC patients.

Regional Variations and Inequalities in Testing for Early Detection of Breast and Cervical Cancer: Evidence From a Nationally Representative Survey in India

BACKGROUND

The burden of cancer in India has been rising, yet testing for early detection remains low. This study explored inequalities in the uptake of breast cancer (BC) examination and cervical cancer (CC) among Indian women, focusing on socioeconomic, regional, and educational differences.

METHODS

Data from the 2019-21 National Family Health Survey (n = 353,518) were used to assess the uptake of BC examination and CC testing. Inequalities were quantified using the slope index of inequality (SII), relative index of inequality (RII), and relative concentration index (RCI). SII measured absolute inequality, while RII and RCI assessed relative inequality between disadvantaged and advantaged groups.

RESULTS

The ever uptake of tests for early detection of BC and CC were low at 9 and 20 per 1,000 women, respectively. Higher uptake was observed among women from the richest households compared to the poorest (SII: 1.1 for BC and 1.8 for CC). The magnitude of relative socioeconomic inequalities was more pronounced in rural areas (RCI: 22.5 for BC and 21.3 for CC) compared to urban areas. Similarly, higher-educated women were 4.84 times (RII: 4.84) and 2.12 times (RII: 2.12) more likely to undergo BC examination and CC testing, respectively, compared to non-educated women. The Northeastern region exhibited greater socioeconomic inequality, while the Western region showed more education-based inequality.

CONCLUSION

The lower uptake of BC examination and CC testing and the marked inequalities underscore the need for targeted interventions to improve access and utilization of testing services, especially among lower-educated women, and those in rural areas.

Revolutionizing prognosis: Introducing cell death index (CDI) as a powerful prognostic tool for CSCC patients

BACKGROUND

Cervical squamous cell carcinoma (CSCC) threatens the body health of women worldwide. This study aimed to foster a new concept of prognostic indicator named cell death index (CDI).

METHODS

RNA-seq and scRNA-seq datasets were downloaded from the GEO and TCGA database as the training and validation cohorts. Programmed cell death (PCD)-related gene signatures were obtained from published research. The construction of prognostic model was performed based on CDI value. Patients with CSCC were divided into high- and low-CDI groups. We explored the differences in overall survival time, immune infiltration, mutation status, and drug sensitivity between high and low CDI groups by R software.

RESULTS

We constructed prognostic model to calculate the CDI value with 23 genes. Patients with high CDI have shorter survival time than those with low CDI. CDI was considered a risk factor compared to other characteristics. The nomogram model estimated overall survival (OS) at 1, 3, and 6 years, with age, Stage, and CDI, indicating the accuracy of the model in predicting 1-, 3-, and 6-year survival rates. CDI values were negatively correlated with most immune checkpoint genes. We measured the significant drug sensitivity of Mitoxantrone, Sabutoclax, Sepantronium bromide, Topotecan, BI-2536, and BMS-754807 between high- and low-CDI groups with significant correlation.

CONCLUSION

This investigation constructed a novel effective prognostic indicator of CDI in patients with CSCC and identified potential genes associated with cell death that could be targeted for prognosis and treatment of CSCC.

Cervical cancer screening uptake and its predictors among women aged 30-49 in Ghana: Providing evidence to support the World Health Organization's cervical cancer elimination initiative

INTRODUCTION

Cervical cancer remains a global health challenge, disproportionately affecting women in low- and middle-income countries, including Ghana. Hence, this study examined the regional variations and predictors of cervical cancer screening uptake among women aged 30-49 in Ghana.

METHODS

Data for this study was obtained from the 2022 Ghana Demographic and Health Survey, comprising 7,124 women aged 30-49. The regional variations in women's uptake of cervical cancer screening was presented using spatial map. A mixed-effect multilevel binary logistic regression was used to examine the factors associated with cervical cancer screening uptake. The results were presented using adjusted odds ratios (aORs) with 95% confidence intervals (CIs).

RESULTS

The uptake of cervical cancer screening was 7.27% [6.33, 8.35] in Ghana. Significant variations in cervical cancer screening existed across regions, with the lowest uptake in Western, Oti, Savannah, and North East regions. Women in rural areas had lower odds of being screened for cervical cancer [aOR = 0.46; 95% CI = 0.28, 0.76] compared to those in urban areas. Women living in the Central, Greater Accra, Volta, Eastern, Ashanti, Ahafo, Bono East, Oti, Northern, North East, Upper East, and Upper West regions all had higher odds of undergoing cervical cancer screening compared to those in the Western region. Women with higher education [aOR = 2.71; 95% CI = 1.23, 5.94] were more likely to be screened for cervical cancer compared to those with no formal education. Women who visited a health facility in the past year had higher odds of being screened for cervical cancer [aOR = 1.48; 95% CI = 1.02, 2.15] relative to those who did not. Reading newspapers or magazines increased the odds of cervical cancer screening uptake [aOR = 1.80; 95% CI = 1.10, 2.92] . Women who belonged to the middle [aOR = 2.19; 95% CI = 1.07, 4.49], richer [aOR = 2.85; 95% CI = 1.28, 6.38], and richest [aOR = 3.08; 95% CI: 1.25, 7.59] wealth indices were more likely to be screened for cervical cancer compared to those in the poorest wealth index.

CONCLUSIONS

Our findings highlight critical disparities in cervical cancer screening uptake in Ghana, particularly emphasizing the need for targeted interventions to address the lower screening rates among women in the Western, Oti, Savannah, and North East regions. The significant association between cervical cancer screening uptake and healthcare access, media exposure, and wealth underscores the importance of enhancing healthcare infrastructure and outreach in underserved regions. To improve screening rates, it is recommended that public health initiatives focus on increasing awareness through community education programs, promoting health facility visits, and leveraging media platforms to disseminate information about cervical cancer screening. Additionally, policies should aim to reduce geographical and socioeconomic barriers, ensuring equitable access to screening services across all regions, especially for women in lower wealth quintiles.

The combined immunization of cervical cancer therapeutic vaccine based on Listeria balanced lethal system has a significant therapeutic effect on tumor model mice

Cervical cancer is the fourth most common cancer and the fourth leading cause of cancer death in women. Effective treatment of cervical cancer is urgently needed. Tumor therapeutic vaccine is a research hotspot in tumor immunotherapy, and the tumor therapeutic vaccine based on attenuated live bacteria carrier has clinical application prospect because of its clear action site and high safety. The bacterial balanced lethal system uses nutritional screening instead of antibiotic screening to avoid the risk of the spread of antibiotic resistance. So it is generally recognized as a green carrier. In our early research, we have constructed two cervical cancer therapeutic vaccine candidates (LM-HPVCW-1 and LI-HPVCW-1) based on Listeria balanced lethal system via transforming the nutrient-deficient strains with nutrition gene complementary plasmid. The complementary plasmid contained the nutrition complementary gene, LM dal gene, and its Amp gene was replaced with asd gene to delete the antibiotic resistance. Besides, it carried the shuffled HPV-16 E6E7 fusion protein gene. In vitro experiments showed that the plasmid carried by the candidate strain could be stably passaged and the target protein could be successfully expressed. In this study, we proved that the two candidate strains were safe in vivo and induced cellular immune response. At the same time, by establishing a tumor-bearing mouse model, it was proved that the two vaccine strains combined immunization could effectively inhibit mouse tumors. The mechanism of tumor suppression may be related to breaking the immunosuppression of tumor microenvironment and inducing CD8+ T cell infiltration. The therapeutic vaccine for cervical cancer constructed in this study is expected to be further applied in clinical practice.

A Systematic Review of Interventions to Promote Cervical Cancer Screening among Immigrant Vietnamese Women

Vietnamese women have a higher incidence rate of cervical cancer and are less likely to have ever been screened for cervical cancer than their White counterparts in the US. This review synthesizes findings from published interventions to promote cervical cancer screening in this vulnerable population. Articles were identified through a systematic search of PsycInfo, Embase, Pubmed, Web of Science, and the Cochrane Register of Controlled Trials in October 2022. Articles were included if they were published in a peer-reviewed journal, written in English, included one or more interventions promoting cervical cancer screening, assessed at least one outcome relevant to screening, and included a sample of ≥ 70% Vietnamese participants. Quality assessment scores were computed using the Downs and Black Checklist. Fifteen articles met review inclusion criteria. Studies were, on average, of good quality. Most studies were conducted in the US (n = 12), used a quasi-experimental design (n = 9), and employed multiple intervention strategies (n = 12). Intervention strategies included educational sessions, lay health worker (LHW) outreach, small media, mass media, patient navigation, and community or healthcare-based strategies. The most common study outcomes were screening intention and receipt. All but two studies reported improved cervical cancer screening outcomes following intervention. Findings support the effectiveness of multicomponent culturally tailored interventions to improve cervical cancer screening outcomes in immigrant Vietnamese women. Further research is needed to determine whether these interventions will be as successful in non-US countries and to address broader community- and healthcare-based factors in screening.

The significance of extensive HPV genotyping for cervical high-grade neoplasia among women with atypical glandular cells

OBJECTIVES

To examine the associated risk of cervical intraepithelial neoplasm grade 3+ (CIN3+) lesions in patients with AGC and extensive human papillomavirus (HPV) genotyping.

METHODS

Cases with atypical glandular cell (AGC) interpretation on a Papanicolaou (Pap) test were identified along with associated extensive HPV genotyping and histologic follow-up results.

RESULTS

Within this cohort of 469,694 Pap tests, 0.4% were diagnosed as AGCs. In total, 1267 cases had concurrent high-risk HPV (hrHPV) genotyping, and 40.3% were hrHPV positive. The percentage of AGC cases with cervical CIN3+ on histologic follow-up was 52.2% when hrHPV was positive, whereas it was 4.9% with a negative hrHPV result. The top 5 hrHPV genotypes associated with cervical CIN3+ in this cohort were HPV16, HPV18, HPV58, HPV52, and HPV33. Indeed, 92.8% of the hrHPV-associated CIN3+ lesions identified in this cohort were positive for at least one of these HPV genotypes. The sensitivity of detecting cervical CIN3+ lesions was 85.6% with the top 5 hrHPV genotypes (HPV16/18/58/52/33) and only increased to 89.0% when the additional 12 genotypes were included.

CONCLUSIONS

In patients with an AGC Pap, the risk of having a cervical CIN3+ lesion is greatly increased by positivity for hrHPV types 16, 18, 58, 52, and/or 33. Incorporating comprehensive HPV genotyping into AGC cytology allows for refined risk stratification and more tailored management strategies.

Implementing High-Risk Human Papillomavirus Self-Sampling for Cervical Cancer Screening in Ghana: A Study (CarciSCAN) Protocol

Background: The World Health Organization (WHO) aims to eliminate cervical cancer by 2030 through a global strategy, centred on high-risk Human papillomavirus (hrHPV)-based screening and treatment. Implementing these strategies in low-resource settings remains challenging, due to barriers associated with limited healthcare infrastructure and patient awareness. Self-sampling for hrHPV has shown higher acceptability and similar diagnostic accuracy compared to clinician-taken samples. This study proposes a protocol to evaluate the clinical efficacy of a cervical cancer screening program utilising hrHPV self-sampling in Ghana.Methods and Analysis: 1000 non-pregnant women aged 30-65 years will be invited to self-collect hrHPV samples. Those testing hrHPV positive will undergo visual inspection with acetic acid. Those diagnosed with high-grade squamous intraepithelial lesions will be offered ablation. In any case where there is a suspicion of invasion, or equivocal diagnosis, biopsies will be taken. Follow-up for women who are test positive for hrHPV and/or undergo treatment, will involve hrHPV self-sampling after 6 months. HrHPV-negative women will rescreen after 3 years. Biopsies will be taken where immediate treatment is not suitable, and women with confirmed or suspected invasive cervical carcinoma will be referred for surgical and/or oncological care. The primary outcome will be the proportion of women successfully screened, defined as the proportion of women with a valid HPV test result out of those invited to attend cervical screening. Secondary outcomes include screening uptake, disease detection rate, hrHPV genotype prevalence, treatment acceptance rate, successful treatment response, missed disease during treatment, number lost to follow-up, and disease recurrence.Discussion: In low-resource settings, hrHPV self-sampling offers an accessible method to increase screening uptake. This study will inform strategies for broader implementation of cervical cancer screening and contribute to achieving the WHO's goal of elimination by 2030.Trial Registration: Ethical approval for this study was obtained from the Kintampo Health Research Centre Institutional Ethics Committee (IEC), Bono East, Ghana, West Africa, on 24 May 2024 (IEC IRB Registration No. 0004854; Study ID: KHRCIEC/2024-03).

Cervical cancer stage distribution and survival outcomes in Africa: a systematic review and meta-analysis

OBJECTIVE

Cervical cancer is a leading cause of cancer-related deaths among women, with a disproportionate burden in sub-Saharan Africa. Understanding the cervical cancer stage and outcomes is crucial for developing effective interventions and reducing its burden. We aimed to undertake a systematic review and meta-analysis of cervical cancer stage distribution and survival outcomes in Africa.

METHODS

We searched MEDLINE, Embase, PubMed, Cochrane Library, Clarivate Analytics Web of Science, and the World Health Organization African Index Medicus database for publications in all languages from the inception of databases to July 2021. A total of 144 studies published between 1978 and 2021 from 33 African countries were included, encompassing 55,747 patients.

RESULTS

We revealed that 53.3% (95% CI 50.9 to 55.6) of cervical cancer cases in Africa were diagnosed at late stages (stage III-IV). This proportion varied significantly across countries and regions, ranging from 7.7% to 86.3%. The study also highlighted disparities by Human Development Index (HDI) grouping, with low HDI countries exhibiting higher proportions of late-stage diagnoses (56.0%, 95% CI 51.6 to 60.4) compared with medium (51.2%, 95% CI 47.5 to 54.9) and high (50.7%, 95% CI 47.0 to 54.5) HDI countries. Notably, there was no stage migration observed over time (p = .53). The median overall survival was 24.0 months (interquartile range, 19.2-39.4).

CONCLUSION

These stage and outcomes data highlight the need for expanding cervical cancer screening and treatment and are crucial for policymakers to develop evidence-based strategies aimed at accelerating the elimination of cervical cancer in Africa. Additionally, standardized data collection and reporting are needed to facilitate better monitoring of cervical cancer outcomes across countries.

Nanotheranostics for gynecological cancers: a path forward for Africa

Nanoparticle-based therapies represent a transformative approach to managing gynecological cancers, offering targeted treatment strategies that minimize harm to healthy tissues while maximizing therapeutic efficacy. Despite their potential, implementing these advanced treatments in Africa is needed by a complex interplay of technological, economic, regulatory, and ethical challenges. This paper examines the current landscape of nanoparticle-based therapies, identifying critical barriers to their adoption, including inadequate infrastructure, high costs, and insufficient regulatory frameworks. Technological deficiencies manifest as a need for advanced nanoparticle synthesis, delivery, and diagnostics equipment, impeding research and clinical applications. Economically, the high production costs of nanoparticles, compounded by limited access to advanced diagnostic and treatment facilities, create significant financial barriers for healthcare systems and patients alike. Additionally, the regulatory environment needs to be more cohesive, characterized by a lack of established protocols and expertise to evaluate the unique properties of nanomedicines. However, opportunities for advancement exist through focused research and development initiatives. Targeted drug delivery systems, early detection methods, and immunotherapy integration are promising avenues to enhance treatment outcomes. Collaborative partnerships between African institutions and international research entities, alongside public-private collaborations, could bolster local capabilities in nanomedicine. To facilitate the integration of nanoparticle-based therapies, African governments must prioritize funding for nanomedicine research, create robust regulatory frameworks, and ensure equitable access to these innovative treatments. A concerted effort involving policy reforms, investment, and collaboration is essential for overcoming existing barriers and realizing the full potential of nanoparticle-based therapies in improving health outcomes for gynecological cancer patients across Africa.

Cervical Cancer Screening Practice and Associated Factors Among School Teachers in Bahir Dar City, North West Ethiopia: A Cross-Sectional Study

Background and Aims

Despite its prioritization by the World Health Organization, improving access to cervical cancer screening remains a challenge in Ethiopia. Educated individuals, particularly teachers, are viewed as key influencers in promoting healthy lifestyles among youth and can significantly contribute to cervical cancer prevention. However, there is a notable gap in research regarding cervical cancer screening practices among female educators in the studied region. This study aimed to assess the cervical cancer screening practices and associated factors among female school teachers in Bahir Dar, Ethiopia, 2024.

Methods

A school-based cross-sectional study was conducted from May 27 to June 28, 2024, involving 561 female school teachers in Bahir Dar City, using a stratified multistage sampling method. Data were gathered through a pretested structured questionnaire, entered in Epi-data version-4.6, and analyzed with SPSS version-23. Bi-variable and multivariable binary logistic regression analyses were performed, considering variables with p values < 0.05 as statistically significant. Multicollinearity was assessed, and the Hosmer-Lemeshow test evaluated the model's fit.

Results

The proportion of female school teachers practicing cervical cancer screening was 14.6% (95% CI: 11.57%-17.66%). Significant factors associated with screening included having more than one lifetime sexual partner (AOR = 2.96, 95% CI: 1.48-4.92), a history of gynecological examinations (AOR = 2.59, 95% CI: 1.28-5.23), a fair understanding of cervical cancer (AOR = 2.16, 95% CI: 1.12-4.17), a positive attitude toward screening (AOR = 3.23, 95% CI: 1.65-6.33), and a high perceived susceptibility to cervical cancer (AOR = 2.57, 95% CI: 1.34-4.93).

Conclusions

Cervical cancer screening rates among female school teachers in Bahir Dar City fall short of the HSTP-II target. Independent predictors of screening include having multiple sexual partners, a history of gynecological exams, knowledge of cervical cancer, attitudes toward screening, and perceived susceptibility. To improve these rates, initiatives should focus on raising awareness and fostering positive attitudes among teachers about cervical cancer and health-seeking behavior.

The impact of DNA tumor viruses in low-to-middle income countries (LMICS): A literature review

DNA viruses are common in the human population and act as aetiological agents of cancer on a large scale globally. They include the human papillomaviruses (HPV), Epstein-Barr virus (EBV), Kaposi sarcoma-associated herpesvirus (KSHV), hepatitis viruses, and human polyomaviruses. Oncogenic viruses employ different mechanisms to induce cancer. Notably, cancer only develops in a minority of individuals who are infected, usually following protracted years of chronic infection. The human papillomaviruses (HPVs) are associated with the highest number of cancer cases, including cervical cancer and other epithelial malignancies. Hepatitis B virus (HBV) and the RNA virus hepatitis C (HCV) are significant contributors to hepatocellular cancer (HCC). Other oncoviruses include Epstein-Barr virus (EBV), Kaposi sarcoma-associated herpes virus (KSHV), human T-cell leukemia virus (HTLV-I), and Merkel cell polyomavirus (MCPyV). The identification of these infectious agents as aetiological agents for cancer has led to reductions in cancer incidence through preventive interventions such as HBV and HPV vaccination, HPV-DNA based cervical cancer screening, antiviral treatments for chronic HBV and HCV infections, and screening of blood for transfusion for HBV and HCV. Successful efforts to identify additional oncogenic viruses in human cancer may provide further understanding of the aetiology and development of cancer, and novel approaches for prevention and treatment. Cervical cancer, caused by HPV, is the leading gynaecological malignancy in LMICs, with high age-standardised incidence and mortality rates, HCC due to HBV is an important cause of cancer deaths, and the burden of other cancer attributable to infections continues to rise globally. Hence, cancers attributable to DNA viruses have become a significant global health challenge. These viruses hence warrant continued attention and interrogation as efforts to understand them further and device further preventive interventions are critical.

Inflammation and thrombotic risk in late-stage cervical cancer: An exploratory study of coagulation and cytokine profiles in a South African cohort

PURPOSE

This exploratory study investigates the possible relationship between inflammation and thrombosis in cervical cancer patients in South Africa, highlighting the need for improved thrombotic risk profiling.

METHODS

Thromboelastography (TEG) was used to assess coagulation parameters in platelet-poor plasma (PPP) from a small cohort of late-stage (III and IV) cervical cancer patients (n = 19) and healthy controls (n = 15). Parameters assessed included clotting time, clot formation speed, and clot strength. A Luminex Multiplex assay was used to measure interferon-γ (IFN-γ), interleukin-1β (IL-1β), IL-6, vascular endothelial growth factor-A (VEGF-A), and tumour necrosis factor-α (TNF-α) in PPP. Haematological profiles were also evaluated.

RESULTS

Cervical cancer patients displayed a significantly shortened clotting time (p = 0.0044) and increased clot strength (p = 0.0003), suggesting enhanced coagulation. IL-1β was notably elevated (p = 0.0200), consistent with an inflammatory environment. Higher lymphocyte, neutrophil, and platelet counts (p = 0.0162, 0.0420, and 0.0374, respectively) were observed, indicating a possible prothrombotic state.

CONCLUSION

These findings suggest a potential link between inflammation and thrombosis in cervical cancer patients. However, due to this study's small sample size and exploratory nature, direct relationships between these factors have yet to be definitively established and remain speculative. Thrombotic risk profiling may still offer value in managing patients, but further investigation is required to confirm these preliminary observations.

Mapping inequalities in health service coverage in Africa: a scoping review

OBJECTIVE

In this scoping review, we aim to consolidate the evidence on inequalities in service coverage in Africa using a comprehensive set of stratifiers. These stratifiers include place of residence, race/ethnicity/culture/language, occupation, gender/sex, religion, education, socioeconomic status and social capital. Our approach provides a more holistic understanding of the different dimensions of inequality in the context of universal health coverage (UHC).

DESIGN

We conducted a scoping review following the Joanna Briggs Institute Manual for Evidence Synthesis.

DATA SOURCES

We searched MEDLINE, Embase, Web of Science, CINAHL, PyscINFO, Cochrane Library, Google Scholar and Global Index Medicus for articles published between 1 January 2005 and 29 August 2022 examining inequalities in utilisation of health services for reproductive, maternal, newborn and child health (RMNCH), infectious or non-communicable diseases in Africa.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We included any empirical research that assessed inequalities in relation to services for RMNCH (eg, family planning), infectious diseases (eg, tuberculosis treatment) and non-communicable diseases (eg, cervical cancer screening) in Africa.

DATA EXTRACTION AND SYNTHESIS

The data abstraction process followed a stepwise approach. A pilot-tested form capturing study setting, inequality assessment and service coverage indicators was developed and finalised. Data were extracted by one reviewer and cross-checked by another, with discrepancies resolved through consensus meetings. If a consensus was not reached, senior reviewers made the final decision. We used a narrative approach to describe the study characteristics and mapped findings against PROGRESS-Plus stratifiers and health service indicators. Quantitative findings were categorised as 'proequity', 'antiequity' or 'equal' based on service utilisation across social groups.

RESULTS

We included 178 studies in our review, most studies published within the last 5 years (61.1%). Most studies assessed inequality using socioeconomic status (70.6%), followed by age (62.4%), education (60.7%) and place of residence (59.0%). Few studies focused on disability, social capital and ethnicity/race and intersectionality of stratifiers. Most studies were on RMNCH services (53.4%) and infectious disease services (43.3%). Few studies were qualitative or behavioural analyses. Results highlight significant inequalities across different equity stratifiers and services with inconsistent trends of inequalities over time after the implementation of strategies to increase demand of services and strengthen health systems.

CONCLUSION

There is a need to examine equity in service coverage for a variety of health conditions among various populations beyond the traditional classification of social groups. This also requires using diverse research methods identifying disparities in service use and various barriers to care. By addressing these knowledge gaps, future research and health system reforms can support countries in moving closer to achievement of UHC targets.

Performance of a Full-Coverage Cervical Cancer Screening Program Using on an Artificial Intelligence- and Cloud-Based Diagnostic System: Observational Study of an Ultralarge Population

BACKGROUND

The World Health Organization has set a global strategy to eliminate cervical cancer, emphasizing the need for cervical cancer screening coverage to reach 70%. In response, China has developed an action plan to accelerate the elimination of cervical cancer, with Hubei province implementing China's first provincial full-coverage screening program using an artificial intelligence (AI) and cloud-based diagnostic system.

OBJECTIVE

This study aimed to evaluate the performance of AI technology in this full-coverage screening program. The evaluation indicators included accessibility, screening efficiency, diagnostic quality, and program cost.

METHODS

Characteristics of 1,704,461 individuals screened from July 2022 to January 2023 were used to analyze accessibility and AI screening efficiency. A random sample of 220 individuals was used for external diagnostic quality control. The costs of different participating screening institutions were assessed.

RESULTS

Cervical cancer screening services were extended to all administrative districts, especially in rural areas. Rural women had the highest participation rate at 67.54% (1,147,839/1,699,591). Approximately 1.7 million individuals were screened, achieving a cumulative coverage of 13.45% in about 6 months. Full-coverage programs could be achieved by AI technology in approximately 1 year, which was 87.5 times more efficient than the manual reading of slides. The sample compliance rate was as high as 99.1%, and compliance rates for positive, negative, and pathology biopsy reviews exceeded 96%. The cost of this program was CN ¥49 (the average exchange rate in 2022 is as follows: US $1=CN ¥6.7261) per person, with the primary screening institution and the third-party testing institute receiving CN ¥19 and ¥27, respectively.

CONCLUSIONS

AI-assisted diagnosis has proven to be accessible, efficient, reliable, and low cost, which could support the implementation of full-coverage screening programs, especially in areas with insufficient health resources. AI technology served as a crucial tool for rapidly and effectively increasing screening coverage, which would accelerate the achievement of the World Health Organization's goals of eliminating cervical cancer.

Effects of screening coverage and screening quality assurance on cervical cancer mortality: Implication for integrated framework to monitor global implementation of cervical cancer screening programmes

Background

Cervical cancer is a global health threat and a manifestation of inequality, and screening is an effective intervention. However, little is known about how screening coverage and quality assurance, influence cervical cancer mortality. We aimed to investigate the association between screening coverage, screening quality assurance and cervical cancer mortality among women from countries at different developmental levels.

Methods

We obtained data on age-standardised mortality from cervical cancer from the GLOBOCAN 2020 database; coverage of cervical cancer screening from World Health Organization (WHO) Global Health Observatory; and cervical screening programme settings and quality assurance from the Cancer Screening in Five Continents (CanScreen5) database. We assessed the dependency of cervical cancer age-standardised mortality on screening coverage and quality assurance by simple and multiple regression models. We also used linear regression models to identify factors that improved the screening coverage.

Results

The study included data from 53 countries. Reduced mortality was associated with increased screening programme quality assurance in 22 high-development countries. In 31 low-development countries, screening coverage in women aged 30-49 years was inversely associated with cervical cancer mortality. Political commitment (documentation of the cervical cancer screening policy as law) and financial support (treatment services provided free of charge) positively associated with screening coverage.

Conclusions

Screening programmes need strengthening commensurate with local resources and context. Priority should be given to improving screening coverage through stronger political commitment and financial support in low-development countries, and to ensuring good performance at all levels in high-development countries.

Psychosocial Burden of Women Who Are to Undergo Additional Diagnostic Procedures Due to Positive Screening for Cervical Cancer

Background/Objectives: This study aimed to evaluate psychosocial burden and its associated factors in women who were referred for additional diagnostic procedures following receipt of a positive cervical-cancer-screening smear result. Methods: A cross-sectional study was performed in a consecutive cohort of only women who received an abnormal Papanicolaou screening result and therefore presented to a gynecologist for additional diagnostic examinations (colposcopy/biopsy/endocervical curettage) at the Clinic for Gynecology and Obstetrics of the Clinical Center. Multivariate linear regression was used for data analysis, with Bonferroni correction applied for multiple comparisons. Results: Significant independent predictors for the occurrence of psychosocial burden-worry in women with a positive Papanicolaou screening test before diagnostic procedures were the use of oral contraceptives (β = -0.174, p < 0.001), alcohol consumption (β = 0.188, p < 0.001), anxiety (β = -0.189, p = 0.001), high burden of depressive symptoms (β = 0.191, p = 0.001) and insufficient knowledge of the meaning of the term dysplasia/precancerous (β = -0.187, p < 0.001), according to the multivariate linear regression. The significant independent predictor for the occurrence of psychosocial burden-satisfaction with information/support in women with a positive Papanicolaou screening test before diagnostic procedures was psychological distress (β = -0.210, p = 0.001). Conclusions: Providing information in order to improve understanding of the term dysplasia/precancerous, as well as identifying which women are at risk of psychosocial burden, may help protect against this potential harm among women who receive a positive cervical-cancer-screening result and may facilitate their intention to undergo further diagnostic procedures.

Prognostic Value of IMP3 Expression in Squamous Cervical Cancer

Cervical cancer remains one of the leading causes of death from malignant diseases in women worldwide. Primary and secondary prevention have led to better outcomes in developed countries, whereas in developing countries, cervical cancer continues to be responsible for an unjustifiably high number of fatalities. The discovery of new tumor biomarkers can lead to earlier diagnosis, better therapeutic decisions, and improved treatment methods. IMP3 is a protein responsible for invasiveness and other aggressive characteristics of tumor processes. Its highly specific expression has been proven in various malignant processes. The level of IMP3 expression in cervical cancer cells could be used as a prognostic factor for a worse disease course. In this study, IMP3 expression was examined in 80 patients who underwent surgery for squamous cell cervical cancer in the first FIGO stage of the disease, and its association with disease-free period and overall survival was investigated. Data analysis did not show a statistically significant association between IMP3 expression and the mentioned primary outcomes, despite its association with clinical-pathological indicators of advanced disease. In conclusion, the analysis of IMP3 protein expression in patients with early-stage cervical cancer is of limited utility.

Early adoption of innovation in HPV prevention strategies: closing the gap in cervical cancer

Cervical cancer (CC) is one of the highest prevailing causes of female cancer-related mortality globally. A significant discrepancy in incidence has been noted between high and low-middle-income countries. The origins of CC have been accredited to the human papillomavirus (HPV) with serotypes 16 and 18 being the most prevalent. HPV vaccines, with 90%-97% efficacy, have proven safe and currently function as the primary prevention method. In addition, secondary prevention by timely screening can potentially increase the 5-year survival rate by >90%. High-precision HPV DNA testing has proven to be both highly sensitive and specific for early detection and is advocated by the WHO. Lack of public awareness, poor screening infrastructure and access to vaccines, socio-cultural concerns, along with economic, workforce-associated barriers and the presence of marginalised communities unable to access services have contributed to a continued high incidence. This article comprehensively analyses the efficacy, coverage, benefits and cost-effectiveness of CC vaccines and screening strategies including the transition from cytological screening to HPV self-sampling, while simultaneously exploring the real-world disparities in their feasibility. Furthermore, it calls for the implementation of population-based approaches that address the obstacles faced in approaching the WHO 2030 targets for CC elimination.

Factors associated with age at first screening for cervical cancer among adult Cape Verdean women: a cross-sectional study

BACKGROUND

Cervical cancer ranks third in terms of cancer incidence and mortality in Cape Verde. Understanding the factors associated with the age of cervical cancer screening (CCS) is essential because it helps identify populations at risk of delayed screening, enabling targeted interventions to ensure timely detection and treatment, ultimately reducing the burden of cervical cancer. We examined the factors associated with age at first screening for cervical cancer among adult Cape Verdean women.

METHODS

Data from the 2020 WHO STEPs survey were used. We analyzed data from 1,082 women aged 30-69 years who had ever screened for cervical cancer. Bivariable and multivariable logistic regression models were computed in STATA version 18.

RESULTS

Overall, 30.6% of women in the study had their first CCS before or at age 30. Except for visits to the health facility within the last 12 months, all variables significantly predicted women's first age for CCS in the crude model. In the adjusted model, women with tertiary education showed greater odds [AORs = 9.85; 95% CI: 4.12-23.54] compared to those with no formal education. Compared to those who were never married, previously married women had significantly lower odds of screening at an early age [AOR = 0.63; 95% CI: 0.39-0.99]. Women without hypertension had higher odds [AOR = 1.66; 95% CI: 1.18-2.34] of early screening compared to those with hypertension. Also, women who were currently working had significantly higher odds of early screening than those unemployed [AOR = 1.49; 95% CI: 1.09-2.04].

CONCLUSION

In conclusion, implementing targeted educational campaigns, addressing socio-economic barriers, and integrating cervical cancer screening into routine healthcare services can increase the early screening uptake among Cape Verdean women. There is a need to integrate CCS in the routine healthcare services of women living with hypertension. Also, the positive association between formal education and age at first screening, it is imperative for the Cape Verdean public health departments to implement comprehensive education programs within schools to promote awareness about CCS.

Bridging the Gap: Immune Checkpoint Inhibitor as an Option in the Management of Advanced and Recurrent Cervical Cancer in Sub-Saharan Africa

Cervical cancer remains a leading cause of cancer-related mortality in women in low and middle-income countries despite efforts to improve prevention and standard-of-care interventions. Sub-Saharan Africa (SSA) leads the numbers for global cervical cancer incidence and mortality, with the majority of the incidence diagnosed in the late stage of the malignancy. Although the global cervical cancer death rate has been on the decline for the last two decades owing to advancements in screening and treatment options, the mortality rate in SSA has not declined very much. Chemotherapy has been the treatment of choice for cervical cancer in SSA without meeting the expected survival outcomes in these patients, with the majority having advanced diseases at diagnosis. Immune checkpoint inhibitors have recently shown clinical promise in improving the survival of patients with advanced cervical cancer and have been integrated into the treatment guidelines in most high-income countries, which have helped further reduce the mortality rate of cervical cancer. However, many SSA countries are yet to fully benefit from using immune checkpoint inhibitors in cervical cancer. In this review, we discuss the challenges hindering the effective use of immune checkpoint inhibitors for advanced cervical cancer in Africa and possible solutions.

Far behind 90-70-90's screening target: the prevalence and determinants of cervical cancer screening among Sub-Saharan African women: evidence from Demographic and Health Survey

BACKGROUND

Cervical cancer screening is the primary goal in 90-70-90 targets to reduce cervical cancer incidence and mortality by identifying and treating women with precancerous lesions. Although several studies have been conducted in Sub-Saharan African (SSA) countries on cervical cancer screening, their coverage was limited to the regional or national level, and/or did not address individual- and community-level determinants, with existing evidence gaps to the wider SSA region using the most recent data. Hence, this study aimed to assess the pooled prevalence and multilevel correlates of cervical cancer screening among women with SSA.

METHODS

This study was conducted using the Demographic Health Survey data (2015-2022) from 11 countries, and a total weighted sample of 124,787 women was considered in the analysis. Using multilevel mixed-effects logistic regression, the influence of each factor on cervical cancer screening uptake was investigated, and significant predictors were reported using the adjusted odds ratio (aOR) with their respective 95% confidence intervals (95% CI).

RESULTS

The overall weighted prevalence of cervical cancer screening was 10.29 (95% CI: 7.77, 11.26), with the highest and lowest screening rates detected in Namibia and Benin at 39.3% (95% CI: 38.05, 40.54) and 0.5% (95% CI: 0.36, 0.69), respectively. Higher cervical screening uptake was observed among women aged 35-49 [aOR = 4.11; 95% CI: 3.69, 4.58] compared to 15-24 years, attending higher education [aOR = 2.71; 95% CI: 2.35, 3.23] than no formal education, being in the richest wealth quintile [aOR = 1.45; 95% CI: 1.26, 1.67], having a recent visit to a health facility [aOR = 1.83; 95% CI: 1.71, 1.95], using contraception [aOR = 1.54; 95% CI: 1.45, 1.64], recent sexual activity [aOR = 3.59; 95% CI: 2.97, 4.34], and listening to the radio [aOR = 1.78; 95%CI: 1.60, 2.15].

CONCLUSION

The overall prevalence of cervical cancer screening in SSA countries was found to be low; only one in every ten women has been screened. Strengthening universal health coverage, and promoting screening programs with an emphasis on rural areas and low socioeconomic status are key to improving screening rates and equity. Additionally, integrating cervical cancer screening with existing reproductive health programs, e.g. contraceptive service would be important.

Looking Back, Moving Forward: Challenges and Opportunities for Global Cervical Cancer Prevention and Control

Despite the introduction of Pap testing for screening to prevent cervical cancer in the mid-20th century, cervical cancer remains a common cause of cancer-related mortality and morbidity globally. This is primarily due to differences in access to screening and care between low-income and high-income resource settings, resulting in cervical cancer being one of the cancers with the greatest health disparity. The discovery of human papillomavirus (HPV) as the near-obligate viral cause of cervical cancer can revolutionize how it can be prevented: HPV vaccination against infection for prophylaxis and HPV testing-based screening for the detection and treatment of cervical pre-cancers for interception. As a result of this progress, the World Health Organization has championed the elimination of cervical cancer as a global health problem. However, unless research, investments, and actions are taken to ensure equitable global access to these highly effective preventive interventions, there is a real threat to exacerbating the current health inequities in cervical cancer. In this review, the progress to date and the challenges and opportunities for fulfilling the potential of HPV-targeted prevention for global cervical cancer control are discussed.

ceRNA Network and WGCNA Analyses of Differentially Expressed Genes in Cervical Cancer Tissues for Association with Survival of Patients

The study aims to search and identify differentially expressed genes (DEGs) in cervical cancer tissues as novel biomarkers to predict cervical cancer prognosis. The Cancer Genome Atlas (TCGA) data on gene expression profiles in cervical cancer were downloaded and analyzed using R software to identify DEGs in cervical cancer tissues. miRNAs targeted by differentially expressed long non-coding RNAs (DElncRNAs) and mRNAs targeted by microRNAs (miRNAs) were identified using the online miRcode, miRTarBase, TargetScan, and miRDB tools. The ceRNA network and lncRNA expression modules in cervical cancer tissues were constructed using weighted gene co-expression network analysis (WGCNA) and analyzed bioinformatically. The Kaplan-Meier analysis was performed to confirm these DEGs as prognostic markers. Immunohistochemical (IHC) analysis was used to verify expression of the hub genes in 10 paired cervical cancer and normal tissues. A total of 1914 DEmRNAs, 210 DElncRNAs, and 67 DEmiRNAs were identified in cervical cancer samples. There were 39 lncRNAs, 19 miRNAs, and 87 mRNAs involved in the ceRNA network and 25 DElncRNAs, three DEmiRNAs, and four mRNAs involved in the ceRNA sub-network. CACNA1C-AS1 was associated with the yellow and blue modules in the ceRNA sub-network, and LIFR-AS1 was associated with the blue module. The DEmRNAs were involved in cancer-related pathways, and three hub genes (i.e., E2F1, CCNB1, and CCNE1) were highly expressed in cervical squamous cell carcinoma and adenocarcinoma tissues and associated with the prognosis of patients. The ceRNA network and WGCNA analyses are useful to identify novel DEGs that can serve as prognostic markers in cervical cancer. The DEGs will be validated in future studies.

Significance of HIV status in cervical cancer patients receiving curative chemoradiation therapy, definitive radiation alone, or palliative radiation in Botswana

BACKGROUND

Cervical cancer associated with human papillomavirus has the highest cancer incidence and mortality for women in Botswana because of a high HIV prevalence and limited screening. This study investigates the significance of HIV on the overall survival (OS) of patients with locally advanced cervical cancer by various treatment categories (curative chemoradiation, definitive radiation [RT] alone, or palliative RT alone).

METHODS

This study included patients diagnosed with cervical cancer between 2013 and 2020, prospectively enrolled in the Botswana Prospective Cancer Cohort. OS based on HIV status and completion of planned treatment regimen was estimated by the Kaplan-Meier method. Comparisons of 2-year OS by HIV status was performed by the log-rank test, univariate and multivariable Cox analyses adjusting for cancer stage, RT dose, number of chemotherapy cycles, and baseline hemoglobin levels.

RESULTS

Of 1131 patients diagnosed with stage IB-IVB cervical cancer, 69.8% were women living with HIV (n = 789). For patients receiving curative chemoradiation, HIV status was not significantly associated with OS in unadjusted (p = .987) and adjusted (p = .578) analyses. For RT only treatment and definitive (high-dose) RT alone, HIV status was significantly associated with OS in unadjusted analysis (HR = 1.77, p = .002; HR = 1.95, p = .014), but not in adjusted analysis (p = .227, p = .73). For patients receiving palliative (low-dose) RT, HIV status was not associated with OS in unadjusted (p = .835) or adjusted analysis (p = .359).

CONCLUSIONS

In Botswana, a resource-limited setting, HIV status had no significant effect on 2-year OS in patients with cervical cancer with well-managed HIV receiving chemoradiation, RT alone, or palliative RT. This demonstrates that patients living with HIV receiving antiretroviral treatment can receive clinically appropriate treatment with no evidence that HIV may lead to poorer outcomes.

Performance of CADM1, MAL and miR124-2 methylation as triage markers for early detection of cervical cancer in self-collected and clinician-collected samples: an exploratory observational study in Papua New Guinea

OBJECTIVE

WHO recommends human papillomavirus (HPV) testing for cervical screening, with triage of high-risk HPV (hrHPV) positive women. However, there are limitations to effective triage for low-resource, high-burden settings, such as Papua New Guinea. In this exploratory study, we assessed the performance of host methylation as triage tools for predicting high-grade squamous intraepithelial lesions (HSIL) in self-collected and clinician-collected samples.

DESIGN

Exploratory observational study.

SETTING

Provincial hospital, same-day cervical screen-and-treat trial, Papua New Guinea.

PARTICIPANTS

44 hrHPV+women, with paired self/clinician-collected samples (4 squamous cell carcinomas (SCC), 19 HSIL, 4 low-grade squamous intraepithelial lesions, 17 normal).

PRIMARY AND SECONDARY OUTCOME MEASURES

Methylation levels of CADM1, MAL and miR124-2 analysed by methylation-specific PCRs against the clinical endpoint of HSIL or SCC (HSIL+) measured using liquid-based-cytology/p16-Ki67 stain.

RESULTS

In clinician-collected samples, MAL and miR124-2 methylation levels were significantly higher with increasing grade of disease (p=0.0046 and p<0.0015, respectively). miR124-2 was the best predictor of HSIL (area under the curve, AUC 0.819) while MAL of SCC (AUC 0.856). In self-collected samples, MAL best predicted HSIL (AUC 0.595) while miR124-2 SCC (AUC 0.812). Combined miR124-2/MAL methylation yielded sensitivity and specificity for HSIL+ of 90.5% (95% CI 69.6% to 98.8%) and 70% (95% CI 45.7% to 88.1%), respectively, in clinician-collected samples, and 81.8% (95% CI 59.7% to 94.8%) and 47.6% (95% CI 25.7% to 70.2%), respectively, in self-collected samples. miR124-2/MAL plus HPV16/HPV18 improved sensitivity for HSIL+ (95.2%, 95% CI 76.2% to 99.9%) but decreased specificity (55.0%, 95% CI 31.5% to 76.9%).

CONCLUSION

miR124-2/MAL methylation is a potential triage strategy for the detection of HSIL/SCC in low-income and middle-income country.

Coverage and Socioeconomic Inequalities in Cervical Cancer Screening in Low- and Middle-Income Countries Between 2010 and 2019

PURPOSE

Cervical cancer screening is vital in addressing the global burden of cervical cancer. In this study, we describe the coverage and socioeconomic inequalities in the coverage of cervical cancer screening in low- and middle-income countries (LMICs).

METHODS

We analyzed data from the women's recode files of the Demographic and Health Surveys conducted in LMICs from 2010 to 2019 with variables on cervical cancer screening. We included women 21 years or older and determined the proportion of women who were screened for cervical cancer by age categories, wealth quintile, type of place of residence, level of education, and marital status. Socioeconomic inequality was measured using the concentration index (CIX) and the slope index of inequality (SII).

RESULTS

A total of 269,506 women from 20 surveys in 16 countries were included in the survey. Generally, there was a low coverage of screening, with lower rates among women age 21-24 years, living in rural areas, in the poorest wealth quintile, with no formal education, and who have never been in union with or lived with a man. The CIX and SII values for screening for cervical cancer were positive (pro-rich) for all the countries except Tajikistan in 2012 where they were negative (pro-poor).

CONCLUSION

The coverage of cervical cancer screening was low in LMICs with variations by the quintile of wealth (pro-rich) and type of place of residence (pro-urban). To achieve the desired impact of cervical cancer screening services in LMICs, the coverage of cervical cancer screening programs must include women irrespective of the type of place and wealth quintiles.

Integration of cervical cancer screening into healthcare facilities in low- and middle-income countries: A scoping review

Cervical cancer is a prevalent disease among women, especially in low- and middle-income countries (LMICs), where most deaths occur. Integrating cervical cancer screening services into healthcare facilities is essential in combating the disease. Thus, this review aims to map evidence related to integrating cervical cancer screening into existing primary care services and identify associated barriers and facilitators in LMICs. The scoping review employed a five-step framework as proposed by Arksey and O'Malley. Five databases (MEDLINE, Maternity Infant Care, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science) were systematically searched. Data were extracted, charted, synthesized, and summarised. A total of 28 original articles conducted in LMICs from 2000 to 2023 were included. Thirty-nine percent of the reviewed studies showed that cervical cancer screening (CCS) was integrated into HIV clinics. The rest of the papers revealed that CCS was integrated into existing reproductive and sexual health clinics, maternal and child health, family planning, well-baby clinics, maternal health clinics, gynecology outpatient departments, and sexually transmitted infections clinics. The cost-effectiveness of integrated services, promotion, and international initiatives were identified as facilitators while resource scarcity, lack of skilled staff, high client loads, lack of preventive oncology policy, territorial disputes, and lack of national guidelines were identified as barriers to the services. The evidence suggests that CCS can be integrated into healthcare facilities in LMICs, in various primary care services, including HIV clinics, reproductive and sexual health clinics, well-baby clinics, maternal health clinics, and gynecology OPDs. However, barriers include limited health system capacity, workload, waiting times, and lack of coordination. Addressing these gaps could strengthen the successful integration of CCS into primary care services and improve cervical cancer prevention and treatment outcomes.

Human Papillomavirus and Associated Cancers: A Review

The human papillomavirus is the most common sexually transmitted infection in the world. Most HPV infections clear spontaneously within 2 years of infection; however, persistent infection can result in a wide array of diseases, ranging from genital warts to cancer. Most cases of cervical, anal, and oropharyngeal cancers are due to HPV infection, with cervical cancer being one of the leading causes of cancer death in women worldwide. Screening is available for HPV and cervical cancer, but is not available everywhere, particularly in lower-resource settings. HPV infection disproportionally affects individuals living with HIV, resulting in decreased clearance, increased development of cancer, and increased mortality. The development of the HPV vaccine has shown a drastic decrease in HPV-related diseases. The vaccine prevents cervical cancer with near 100% efficacy, if given prior to first sexual activity. Vaccination uptake remains low worldwide due to a lack of access and limited knowledge of HPV. Increasing awareness of HPV and access to vaccination are necessary to decrease cancer and HPV-related morbidity and mortality worldwide.

Pursuance of a Yoruba name for cervical cancer in Southwest Nigeria: a case study

OBJECTIVES

Participants' comprehension of research process affects the quality of research output, which is the reason why translation of research instruments into local languages is standard practice. Literature has consistently reported that in Africa, knowledge about cervical cancer is low but paradoxically, expressed, and actual uptake of human papillomavirus vaccine for its prevention is high. This study explored the Yoruba names of cervical cancer among Yoruba people in Ibadan, Nigeria to guide the translation of cervical cancer research instruments to Yoruba language.

DESIGN

Exploratory case study design was used and data were obtained with 10 in-depth interviews and four focused group discussions. Data were analysed using content analysis.

SETTINGS

The study took place in Ibadan North local government area, Southwest Nigeria.

PARTICIPANTS

These were 4 traditional healers, 3 Yoruba linguists, 3 public health educators and 38 parents of adolescents.

MEASURES

These were Yoruba names for cervical cancer and their meanings.

RESULTS

Participants were aware of cervical cancer but only the traditional healers and public health educators had names for it. These names were highly varied. The public health educators gave names that were linked with different parts of the female reproductive system and external genital which were actually different medical conditions. Each traditional healer also had different names for cervical cancer, which either described the female body parts, or symptoms of female genital infections. These various names can lead to unnecessary misconceptions and misinformation about cervical cancer, its prevention, management, and research.

CONCLUSIONS

There was no consensus Yoruba name for cervical cancer among the study participants. Efforts to educate the Yoruba speaking populace about cervical cancer, its prevention, management and participation in its research can be frustrated if a generally accepted Yoruba name is not provided for this cancer. Stakeholders' collaboration is required to get an appropriate Yoruba name for cervical cancer.

Cervical cancer screening outcomes for HIV-positive women in the Lubombo and Manzini regions of Eswatini-Prevalence and predictors of a positive visual inspection with acetic acid (VIA) screen

This study aimed to describe the prevalence and predictors of a positive VIA (visual inspection with acetic acid) cervical cancer screening test in women living with human immunodeficiency virus (HIV). We retrospectively analysed data from women aged ≥15 who accessed VIA screening from health facilities in the Lubombo and Manzini regions of Eswatini. Sociodemographic and clinical data from October 2020 to June 2023 were extracted from the client management information system (CMIS). VIA screening outcome was categorised into negative, positive, or suspicious. A logistic regression model estimated the adjusted odds ratio (AOR) of the predictors of a positive VIA screen at p<0.05 with 95% confidence intervals. Of 23,657 participants, 60.8% (n = 14,397) were from the Manzini region. The mean age was 33.3 years (standard deviation 7.0), and 33% (n = 7,714) were first-time screens. The prevalence of a positive VIA was 2.6% (95% CI: 2.2%, 3.0%): 2.8% (95% CI: 2.2%, 3.5%) in Lubombo and 2.4% (95% CI: 2.0%, 2.9%) in Manzini (p = 0.096). Screening at mission-owned (AOR 1.40; p = 0.001), NGO-owned (AOR 3.08; p<0.001) and industrial/workplace-owned health facilities (AOR 2.37; p = 0.044) were associated with increased odds of a positive VIA compared to government-owned health facilities. Compared to those aged 25-34, the odds of a positive VIA increased by 1.26 for those in the 35-44 age group (AOR 1.26; p = 0.017). Predictors with lower odds for a positive VIA test were: being on anti-retroviral therapy (ART) for 5-9 years (AOR 0.76; p = 0.004) and ≥10 years (AOR 0.66; p = 0.002) compared to <5 years; and having an undetectable viral load (AOR 0.39; p<0.001) compared to unsuppressed. Longer duration on ART and an undetectable viral load reduced the odds, while middle-aged women and screening at non-public health facilities increased the odds of a positive VIA screen.

Factors associated with late diagnosis of cervical cancer at two national referral hospitals, Kenya 2017: A case control study

Background

Cervical cancer is the leading cause of cancer mortality among women in Kenya. Two thirds of cervical cancer cases in Kenya are diagnosed in advanced stages. We aimed to identify factors associated with late diagnosis of cervical cancer, to guide policy interventions.

Methods

An unmatched case control study (ratio 1:2) was conducted among women aged ≥ 18 years with cervical cancer at Kenyatta National and Moi Teaching and Referral Hospitals. We defined a case as patients with International Federation of Gynecology and Obstetrics (FIGO) stage ≥ 2A and controls as those with stage ≤ 1B. A structured questionnaire was used to document exposure variables. We calculated adjusted odds ratio (aOR) to identify any associations.

Results

We enrolled 192 participants (64 cases, 128 controls). Mean age 39.2 (±9.3) years, 145 (76 %) were married, 77 (40 %) had primary level education, 168 (88 %) had their first pregnancy ≤ 24 years of age, 85 (44 %) were > para 3 and 150 (78 %) used contraceptives. Late diagnosis of cervical cancer was associated with cost of travel to cancer centres > USD 6.1 (aOR 6.43 95% CI [1.30, 31.72]), age > 50 years (aOR 4.71; 95% CI [1.18, 18.80]), anxiety over cost of cancer care (aOR 5.6; 95% CI [1.05, 32.72]) and ultrasound examination during evaluation of symptoms (aOR 4.89; 95% CI [1.07-22.42]). Previous treatment for gynecological infections (aOR 0.10; 95% CI [0.02, 0.47]) was protective against late diagnosis.

Conclusion

Cost of seeking care and the quality of the diagnostic process were important factors in this study. Decentralization of care, innovative health financing solutions and clear diagnostic and referral algorithms for women presenting with gynecological symptoms could reduce late-stage diagnosis in Kenya.

A portable all-in-one microfluidic device with real-time colorimetric LAMP for HPV16 and HPV18 DNA point-of-care testing

Screening for high-risk human papillomavirus (HPV) infection is one of the most important preventative measures for cervical cancer. However, fast, convenient, and low-cost HPV detection remains challenging, especially in resource-limited settings. Here, we report a portable all-in-one device (PAD) for point-of-care testing (POCT) for HPV16 and HPV18 DNA in cervical swabs. The PAD was engineered to integrate modules for extraction-free sample lysis, loop-mediated isothermal amplification (LAMP) with lyophilized reagent beads, and real-time colorimetric signal sensing into a single miniaturized device, considerably shortening the sample-to-result time to 15 min. The precision liquid handling in the completely sealed microfluidic chip is achieved by a uniquely designed pressure-balanced automatic liquid flow mechanism, thereby eliminating the need for manual manipulation of liquids and thus the risk of biohazards. The PAD employs an improved real-time colorimetric LAMP (rcLAMP) assay with a limit of detection (LOD) of 1 copy/μL, enabled by enhanced assay chemistry to maximize the reaction kinetics. To validate this device for clinical application, we tested 206 clinical cervical swab samples and obtained a sensitivity of 92.1% and a specificity of 99.0%. This custom PAD enabled by microfluidic and electronic engineering techniques can be configured for the simultaneous detection of HPV16 and HPV18 or other pathogens in point-of-care applications.

Uptake of cervical cancer screening and associated factors among human immune virus positive women attending antiretroviral therapy clinic in public health facilities, Northeast Ethiopia, 2022: A cross-sectional study

Background

Although cervical cancer is the most prevalent cancer in women and has a high morbidity, mortality, and low quality of life burden among human immune virus-positive women, there is little evidence of it in northeastern Ethiopia.

Objective

Sought to determine the magnitude and associated factors of cervical cancer screening among human immune virus-positive women in public health facilities in northeastern Ethiopia.

Methods and material

A multicentered, institution-based cross-sectional study with 401 participants using the systematic random sampling technique was employed. The data was gathered through personal interviews and chart reviews. The predictors were established via multivariate logistic regression analysis.

Result

The magnitude of cervical cancer screening was 19.2% (15.7%-22.9%). Multiparity, bad obstetric history, hearing about cervical cancer, recommendations from medical professionals, duration of antiretroviral therapy >10 years, a family record of cervical cancer, and knowing cervical cancer were revealed to be predictors of testing for cervical cancer.

Conclusion

The magnitude of cervical cancer screening was 19.2% (15.7%-22.9%). Multiparity, bad obstetric history, hearing about cervical cancer, recommendations from medical professionals, duration of antiretroviral therapy >10 years, a family record of cervical cancer, and knowing cervical cancer were revealed to be predictors of testing for cervical cancer.

Integration of cervical cancer screening into healthcare facilities in low- and middle-income countries: a scoping review protocol

BACKGROUND

Cervical cancer is the fourth most common malignancy in women, with 90% of deaths in low- and middle-income countries. Integrating cervical cancer screening services into healthcare facilities is crucial for overcoming the disease. Thus, this review aims to map existing evidence and identify barriers and facilitators in low- and middle-income countries.

METHODS

The scoping review will employ a five-step framework as proposed by Arksey and O'Malley. These are (1) formulating the research questions, (2) identifying relevant studies, (3) selecting eligible studies, (4) charting the data, and (5) collating, summarising and reporting the results. Five databases (MEDLINE, Maternity and Infant Care, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science) will be systematically searched. Grey literature will also be searched. Data will be extracted, charted, synthesised and summarised.

ETHICS AND DISSEMINATION

This review does not require ethics approval. Findings will be disseminated through peer-reviewed publications, policy briefs and conference presentations.

Efficacy and safety of therapeutic HPV vaccines to treat CIN 2/CIN 3 lesions: a systematic review and meta-analysis of phase II/III clinical trials

OBJECTIVES

We aim to assess the efficacy and safety of therapeutic human papillomavirus (HPV) vaccines to treat cervical intraepithelial neoplasia of grade 2 or 3 (CIN 2/3).

DESIGN

Systematic review and meta-analysis, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations.

DATA SOURCES

PubMed, Embase, Web of Science, Global Index Medicus and CENTRAL Cochrane were searched up to 31 January 2022.

ELIGIBILITY CRITERIA

Phase II/III randomised controlled trials (RCTs) and single-arm studies reporting the efficacy of therapeutic vaccines to achieve regression of CIN 2/3 lesions were included. Studies evaluating only safety and side effects of the vaccine were excluded.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers extracted data and evaluated study quality. A random-effect model was used to pool the proportions of regression and/or HPV clearance.

RESULTS

12 trials met the inclusion criteria. Out of 734 women (all studies considered) receiving therapeutic HPV vaccine for CIN 2/3, 414 regressed to normal/CIN 1 with an overall proportion of regression of 0.54 (95% CI 0.39 to 0.69) for vaccinated group; 166 women (from five RCTs) receiving placebo only achieving a pooled normal/CIN 1 regression of 0.27 (95% CI 0.20 to 0.34). When including only the five two-arm studies, the regression proportion for the 410 vaccine group participants was higher than that of the 166 control group participants (relative risk (RR) 1.52; 95% CI 1.14 to 2.04). The pooled proportion of high-risk human papillomavirus (hrHPV) clearance was 0.42 (95% CI 0.32 to 0.52) in the vaccine group (six studies with a total of 357 participants) and 0.17 (95% CI 0.11 to 0.26) in the control group (three RCTs with a total of 104 participants). Based on these three RCTs, the hrHPV clearance was significantly higher in the vaccinated group (250 participants) compared with the control group (RR 2.03; 95% CI 1.30 to 3.16). Similar results were found regarding HPV 16/18 clearance. No significant unsolicited adverse events have been consistently reported.

CONCLUSIONS

The efficacy of the therapeutic vaccines in the treatment of CIN 2/3 was modest. Implementation issues such as feasibility, acceptability, adoption and cost-effectiveness need to be further studied.

Molecular triaging options for women testing HPV positive with self-collected samples

We review developments in molecular triaging options for women who test positive for high-risk human papillomavirus (hrHPV) on self-collected samples in the context of cervical cancer elimination. The World Health Organization (WHO) recommends hrHPV screening as the primary test for cervical screening due to its high sensitivity compared to other screening tests. However, when hrHPV testing is used alone for treatment decisions, a proportion of women of childbearing age receive unnecessary treatments. This provides the incentive to optimize screening regimes to minimize the risk of overtreatment in women of reproductive age. Molecular biomarkers can potentially enhance the accuracy and efficiency of screening and triage. HrHPV testing is currently the only screening test that allows triage with molecular methods using the same sample. Additionally, offering self-collected hrHPV tests to women has been reported to increase screening coverage. This creates an opportunity to focus health resources on linking screen-positive women to diagnosis and treatment. Adding an additional test to the screening algorithm (a triage test) may improve the test's positive predictive value (PPV) and offer a better balance of benefits and risks for women. Conventional triage methods like cytology and visual inspection with acetic acid (VIA) cannot be performed on self-collected samples and require additional clinic visits and subjective interpretations. Molecular triaging using methods like partial and extended genotyping, methylation tests, detection of E6/E7 proteins, and hrHPV viral load in the same sample as the hrHPV test may improve the prediction of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and invasive cancer, offering more precise, efficient, and cost-effective screening regimes. More research is needed to determine if self-collected samples are effective and cost-efficient for diverse populations and in comparison to other triage methods. The implementation of molecular triaging could improve screening accuracy and reduce the need for multiple clinical visits. These important factors play a crucial role in achieving the global goal of eliminating cervical cancer as a public health problem.

Implementation of Brachytherapy for Patients With Cervical Cancer in Ethiopia: A 3-Year Practice Report

PURPOSE

Although cervical cancer is the second most commonly diagnosed cancer in Ethiopia, brachytherapy (BT) was not a component in patient treatment until 2015. The purpose of this study was to identify the patterns of utilization as well as to describe the practice of BT in Ethiopia.

MATERIALS AND METHODS

A retrospective descriptive data analysis of 138 patients with cervical cancer treated with a curative potential using BT from 2015 to 2018 at Tikur Anbassa Specialized Hospital, which housed the only BT facility in Ethiopia during the study period.

RESULTS

During the first 3-year period of BT service commencement, each year n = 37, n = 36, and n = 65 patients with cervical cancer were treated, respectively, with curative intention treatment. The median age of these 138 patients was 50 years (range, 22-75). All the patients were in International Federation of Gynecology and Obstetrics stage Ib-IIIb group, and stage IIb (66.4%) was the predominant. Majority (79%) of the patients were treated primarily with radiotherapy (RT), while 21% received RT after surgery. More than half of these patients (62%) received a total RT dose of 82 Gy in equivalent dose in 2 Gy fractions (EQD2), while the rest received a dose ranging from 76 to 86 Gy. Concurrent cisplatin with RT was given only for 36% of the patients for undocumented reasons. The overall treatment time including both external-beam RT and BT was greater than 8 weeks in 21% of the patients.

CONCLUSION

The utilization of BT service increased gradually and BT enabled the delivery of a higher RT dose to patients with cervical cancer (mostly stage IIB). However, there was protracted treatment duration and low concurrent chemotherapy utilization.

Factors influencing the prevalence of cervical cancer screening in Malaysia: a nationwide survey

BACKGROUND

In 2020, cervical cancer ranked fourth in terms of both frequency of diagnosis and the leading cause of cancer-related deaths among women globally. Among Malaysian women, it was the third most prevalent form of cancer. Published data on nationally representative cervical cancer screening in Malaysia have been limited. Therefore, this study aimed to determine the prevalence of receiving a Pap smear test in the past three years, its relationship with socio-demographic factors and physical activity.

METHODS

Using a subset of survey data from the National Health and Morbidity Survey (NHMS) 2019, a secondary data analysis was performed. Trained research assistants collected data through face-to-face method using a mobile tablet questionnaire system application. Logistic regression analysis was performed to examine the relationship between sociodemographic factors, physical activity, and cervical cancer screening. The analyses were conducted using STATA version 14 (Stata Corp, College Station, Texas, USA), accounting for sample weighs and complex sampling design.

RESULTS

The analysis included 5,650 female respondents, representing an estimated 10.3 million Malaysian female adults aged 18 and above. Overall, 35.2% (95%CI 33.2, 37.4) respondents had a Pap smear test within the past three years. Respondents who were physically active were 1.41 times more likely to have a Pap smear test. Similarly, respondents aged 35-59 (OR 1.84; 95%CI 1.46, 2.34) and those living in rural localities (OR 1.38; 95%CI 1.13, 1.70) had higher odds of receiving a Pap smear test. Compared to married respondents, single respondents (OR 0.04; 95%CI 0.02, 0.07) and widowed/divorcee respondents (OR 0.72; 95%CI 0.56, 0.82) were less likely to receive a Pap smear test. Educated respondents were more likely to have had a Pap smear test.

CONCLUSIONS

The overall prevalence of cervical cancer screening in Malaysia remains low (35.2%). Efforts should be made to strengthen health promotion programs and policies in increasing awareness on the significance of cervical cancer screening. These initiatives should specifically target younger women, single women, and widowed/divorced individuals. The higher cervical screening uptake among rural women should be studied further, and the enabling factors in the rural setup should be emulated in urban areas whenever possible.

Lumican is a potential predictor on the efficacy of concurrent chemoradiotherapy in cervical squamous cell carcinoma

Purpose

To identify new novel biomarkers for predicting the efficacy of concurrent chemoradiotherapy(CCRT) in cervical squamous cell carcinoma(CESC).

Methods

Gene expression datasets GSE56363, GSE5787, and GSE168009 were analyzed to identify candidate genes to predict the efficacy of CCRT in CESC. Single-cell RNA sequencing (scRNA-seq) data from GSE168652 and CESC patients in The Cancer Genome Atlas(TCGA) were systematically analyzed to explore possible molecular mechanisms. Kaplan-Meier evaluated the correlation between LUM (Lumican) and prognostic significance. The expression of LUM protein in biopsy tissues before CCRT was detected by immunohistochemistry in 15 CESC patients.

Results

LUM mRNA levels were significantly upregulated in nonresponders of CESC.patients receiving CCRT and positively correlated with poor therapeutic effect. Furthermore, high expression of LUM influenced the immune microenvironment in CESC patient-derived organoids treated with CCRT. LUM overexpression in CESC cells induced resistance to CCRT, potentially via immune landscape modulation. Gene Set Enrichment Analysis (GSEA) revealed that possible mechanisms underlying resistance to CCRT might involve the PARs and IL1 signaling pathway affecting the immune landscape.

Conclusions

High LUM expression is correlated with poor efficacy in CESC patients receiving CCRT, possibly through the PARs and IL1 signaling pathway affecting the immune landscape.

Strategies to eliminate cervical cancer in China

Cervical cancer is a widely distributed disease that is preventable and controllable through early intervention. The World Health Organization has identified three key measures, coverage populations and coverage targets to eliminate cervical cancer. The WHO and several countries have conducted model predictions to determine the optimal strategy and timing of cervical cancer elimination. However, specific implementation strategies need to be developed in the context of local conditions. China has a relatively high disease burden of cervical cancer but a low human papillomavirus vaccination rate and cervical cancer screening population coverage. The purpose of this paper is to review interventions and prediction studies for the elimination of cervical cancer and to analyze the problems, challenges and strategies for the elimination of cervical cancer in China.

Cervical cancer screening utilization and its predictors among women in bench Sheko Zone, Southwest Ethiopia: using health belief model

BACKGROUND

Cervical cancer is the fourth most frequently diagnosed and found to be the leading cause of cancer death in women, especially in low and middle-income countries. Even though cervical cancer is a preventable disease, its preventive measures have not been equitably implemented across and within different countries; especially in low and middle-income countries, due to different contributing factors.

OBJECTIVE

This study aimed to assess cervical cancer screening utilization and its' predictors among Women in Bench Sheko Zone, Southwest Ethiopia.

METHOD

A community-based cross-sectional study design was employed in Bench Sheko Zone from February 2021 to April 2021. Using a multi-stage stratified sampling method, a total of 690 women in the age range of 30-49 years were included in the study. The logistic regression analysis was used considering a 95% confidence interval and a P-value of < 0.05.

RESULTS

Ninety-six (14.2%) of the participants have utilized cervical cancer screening. Predictors like; age between 40-49 years (AOR = 5.35, 95% CI = [2.89, 9.90]), partner educational status of certificate and above (AOR = 4.36, 95% CI = [1.65, 11.51]), first sexual intercourse before eighteen years (AOR = 4.85, 95% CI = [2.29, 10.26]), ever used of alcohol (AOR = 3.99, 95% CI = [1.23, 12.89]), good knowledge (AOR = 8.98, 95% CI = [4.06, 19.89]), favorable attitude (AOR = 3.56, 95% CI = [1.78, 7.09]), and high perceived benefit (AOR = 2.94, 95% CI = [1.48, 5.84]) were strongly associated with cervical cancer screening utilization.

CONCLUSION

In this study, cervical cancer screening utilization was relatively low. Therefore, promotion of the perception of women towards cervical cancer screening, and provision of health-related information towards different behavioral-related factors should have to be addressed at each level of health care.

[Faible niveau de dépistage du cancer du col de l'utérus, disparités géographiques et déterminants sociodémographiques du dépistage chez les femmes adultes au Burkina Faso : résultats de la première enquête nationale en population générale]

OBJECTIVE

To explore the level, geographical disparities and sociodemographic determinants of cervical cancer screening uptake among adult women in Burkina Faso by using data from the first national population-based survey.

METHODS

This was a cross-sectional secondary analysis of primary data obtained by the 2013 World Health Organization (WHO) Stepwise Approach to Surveillance survey conducted in Burkina Faso. All 13 Burkinabè regions, with their different rates of urbanization, were surveyed. Lifetime cervical cancer screening uptake was explored. We included 2293 adult women for analyses and performed Student's t, chi-square and Fisher's exact tests, and logistic regression.

RESULTS

Only 6.2% (95% CI: 5.3-7.3) of women had ever been screened for cervical cancer. For two regions ("Centre" and "Hauts-Bassins"), the pooled frequency was 16.6% (95% CI: 13.5-20.1) while in the other eleven regions it was significantly lower, 3.3% (95% CI: 2.5-4.2). In urban and rural areas, the respective frequencies for the screening uptake were 18.5% and 2.8% (p < 0.001), and in educated and un-educated women, frequencies were 27.7% and 3.3% (p < 0.001) respectively. The sociodemographic factors associated with screening uptake were being educated (adjusted odd-ratio [aOR] = 4.3; 95% CI: 2.8-6.7), urban residence (aOR = 3.8, 95% CI: 2.5-5.8) and having an occupation providing income (aOR = 3.1, 95% CI: 1.8-5.4).

CONCLUSION

There was a significantly wide range in screening uptake between Burkina Faso regions, and the overall national as well as the region-specific levels were far below the WHO's target for cervical cancer elimination. Cervical cancer interventions should be tailored specifically for Burkinabè women with different educational levels, and prevention strategies based on community engagement integrating psychosocial considerations could be helpful.

CanScreen5, a global repository for breast, cervical and colorectal cancer screening programs

The CanScreen5 project is a global cancer screening data repository that aims to report the status and performance of breast, cervical and colorectal cancer screening programs using a harmonized set of criteria and indicators. Data collected mainly from the Ministry of Health in each country underwent quality validation and ultimately became publicly available through a Web-based portal. Until September 2022, 84 participating countries reported data for breast (n = 57), cervical (n = 75) or colorectal (n = 51) cancer screening programs in the repository. Substantial heterogeneity was observed regarding program organization and performance. Reported screening coverage ranged from 1.7% (Bangladesh) to 85.5% (England, United Kingdom) for breast cancer, from 2.1% (Côte d'Ivoire) to 86.3% (Sweden) for cervical cancer, and from 0.6% (Hungary) to 64.5% (the Netherlands) for colorectal cancer screening programs. Large variability was observed regarding compliance to further assessment of screening programs and detection rates reported for precancers and cancers. A concern is lack of data to estimate performance indicators across the screening continuum. This underscores the need for programs to incorporate quality assurance protocols supported by robust information systems. Program organization requires improvement in resource-limited settings, where screening is likely to be resource-stratified and tailored to country-specific situations.

Lifetime prevalence and adherence rate of cervical cancer screening among women living with HIV: a systematic review and meta-analysis

INTRODUCTION

Women living with HIV (WLWH) are more likely to develop cervical cancer. Screening and available healthcare can effectively reduce its incidence and mortality rates. We aimed to summarize the lifetime prevalence and adherence rate of cervical cancer screening among WLWH across low- and middle-income countries (LMICs), and high-income countries (HICs).

METHODS

We systematically searched PubMed, Web of Science and Embase for studies published between database inception and 2 September 2022, without language or geographical restrictions. Those reporting the lifetime prevalence and/or adherence rate of cervical cancer screening among WLWH were included. Pooled estimates across LMICs and HICs were obtained using DerSimonian-Laird random-effects models. When the number of eligible studies was greater than 10, we further conducted stratified analyses by the World Health Organization (WHO) region, setting (rural vs. urban), investigation year, screening method, type of cervical cancer screening programme, age and education level.

RESULTS

Among the 63 included articles, 26 provided data on lifetime prevalence, 24 on adherence rate and 13 on both. The pooled lifetime prevalence in LMICs was 30.2% (95% confidence interval [CI]: 21.0-41.3), compared to 92.4% in HICs (95% CI: 89.6-94.6). The pooled adherence rate was 20.1% in LMICs (95% CI: 16.4-24.3) and 59.5% in HICs (95% CI: 51.2-67.2).

DISCUSSION

There was a large gap in cervical cancer screening among WLWH between LMICs and HICs. Further analysis found that those in LMICs had higher lifetime prevalence in subgroups with urban settings, with older age and with higher education levels; and those in HICs had higher adherence in subgroups with younger age and with higher education levels.

CONCLUSIONS

Cervical cancer screening among WLWH falls considerably short of the WHO's goal. There should be continuous efforts to further increase screening among these women, especially those residing in the rural areas of LMICs and with lower education levels.

Long non-coding RNAs as critical regulators and novel targets in cervical cancer: current status and future perspectives

Cervical cancer is among the leading causes of cancer-associated mortality in women. In spite of vaccine availability, improved screening procedures, and chemoradiation therapy, cervical cancer remains the most commonly diagnosed cancer in 23 countries and the leading cause of cancer deaths in 36 countries. There is, therefore, a need to come up with novel diagnostic and therapeutic targets. Long non-coding RNAs (lncRNAs) play a remarkable role in genome regulation and contribute significantly to several developmental and disease pathways. The deregulation of lncRNAs is often observed in cancer patients, where they are shown to affect multiple cellular processes, including cell cycle, apoptosis, angiogenesis, and invasion. Many lncRNAs are found to be involved in the pathogenesis as well as progression of cervical cancer and have shown potency to track metastatic events. This review provides an overview of lncRNA mediated regulation of cervical carcinogenesis and highlights their potential as diagnostic and prognostic biomarkers as well as therapeutic targets for cervical cancer. In addition, it also discusses the challenges associated with the clinical implication of lncRNAs in cervical cancer.

Cost-effectiveness of the screen-and-treat strategies using HPV test linked to thermal ablation for cervical cancer prevention in China: a modeling study

BACKGROUND

Self-sampling HPV test and thermal ablation are effective tools to increase screening coverage and treatment compliance for accelerating cervical cancer elimination. We assessed the cost-effectiveness of their combined strategies to inform accessible, affordable, and acceptable cervical cancer prevention strategies.

METHODS

We developed a hybrid model to evaluate costs, health outcomes, and incremental cost-effectiveness ratios (ICER) of six screen-and-treat strategies combining HPV testing (self-sampling or physician-sampling), triage modalities (HPV genotyping, colposcopy or none) and thermal ablation, from a societal perspective. A designated initial cohort of 100,000 females born in 2015 was considered. Strategies with an ICER less than the Chinese gross domestic product (GDP) per capita ($10,350) were considered highly cost-effective.

RESULTS

Compared with current strategies in China (physician-HPV with genotype or cytology triage), all screen-and-treat strategies are cost-effective and self-HPV without triage is optimal with the most incremental quality-adjusted life-years (QALYs) gained (220 to 440) in rural and urban China. Each screen-and-treat strategy based on self-collected samples is cost-saving compared with current strategies (-$818,430 to -$3540) whereas more costs are incurred using physician-collected samples compared with current physician-HPV with genotype triage (+$20,840 to +$182,840). For screen-and-treat strategies without triage, more costs (+$9404 to +$380,217) would be invested in the screening and treatment of precancerous lesions rather than the cancer treatment compared with the current screening strategies. Notably, however, more than 81.6% of HPV-positive women would be overtreated. If triaged with HPV 7 types or HPV16/18 genotypes, 79.1% or 67.2% (respectively) of HPV-positive women would be overtreated with fewer cancer cases avoided (19 cases or 69 cases).

CONCLUSIONS

Screen-and-treat strategy using self-sampling HPV test linked to thermal ablation could be the most cost-effective for cervical cancer prevention in China. Additional triage with quality-assured performance could reduce overtreatment and remains highly cost-effective compared with current strategies.
