Methylation Analysis to Detect CIN3+ in High-Risk Human Papillomavirus-Positive Self-Samples From the Population-Based Cervical Cancer Screening Program

Since 2017, a self-sampling device has been introduced to the Dutch population-based screening program to enable higher participation rates. However, routine triage cytology cannot be performed on self-sampling material. Methylation is an alternative triage method that can be performed directly on DNA extracted from self-samples. Recently, we tested a set of 15 published cervical intraepithelial neoplasia grade 3 or worse (CIN3+)-specific methylation markers and found a panel of 3 markers with a sensitivity of 82% and a specificity of 74%. In this study, we determined the sensitivity and specificity of 2 commercial assays using quantitative methylation-specific PCR. DNA from the same cohort of high-risk human papillomavirus-positive self-sampled material obtained through the population-based screening program in the North of the Netherlands from women with CIN2 or less (<CIN3, n = 208) and women with CIN3+ (n = 96) was used. The QIAsure methylation test (consisting of 2 methylation markers) showed a sensitivity of 65% and a specificity of 72%, whereas the Gyntect assay (consisting of 6 methylation markers) showed a sensitivity of 59% and a specificity of 91% for CIN3+. When we compared all individual 23 methylation markers, receiver operating characteristic analysis showed an area under the curve of ≥0.7 for 11 of 23 markers (P < .001). By model-based recursive partitioning and robustness analysis, we found a panel with a better sensitivity compared with QIAsure and Gyntect (P < .001). This new panel, consisting of ITGA4, ASCL1, and FAM19A4, has a sensitivity of 84% and a specificity of 70%, similar to our previously identified panel (ANKRD18CP, LHX8, and EPB41L3). Thus, in addition to our previously identified panel, the combination of ITGA4, ASCL1, and FAM19A4 showed good diagnostic performance and potentially can replace cytology, thereby avoiding additional doctor visits for many women worldwide and reducing the time for decision making for referral to the gynecologist.

Evolution of Pathological Techniques for the Screening of Cervical Cancer: A Comprehensive Review.

The evolutionary journey of cervical cancer screening has been a major medical success story, considering the substantial role it has played in dwindling the disease burden. Through sustained collaborative efforts within the medical community, significant advances have been made from the humble yet path-breaking conventional Pap smear to the current automated screening systems and human papillomavirus(HPV) molecular testing. With the integration of artificial intelligence into screening techniques, we are currently at the precipice of circumventing the pitfalls of manual cytology readings and improving the efficiency of the screening systems by a significant margin. Despite the technological milestones traversed, the high logistics and operational cost, besides the technical know-how of operating the automated systems, can pose a major practical challenge in the widespread adoption of these advanced techniques in cervical cancer screening programs. This would suggest the need to adopt strategies that are tailored to the demands and needs of the different settings keeping their limitations in mind. This review aims to take the reader through the entire evolutionary journey of cervical cancer screening programs, highlight the individual merits and demerits of each technique, and discuss the recommendations from the major global guidelines.

Correlates of intention to screen for cervical cancer among adult women in Kyotera District, Central Uganda: a community based cross-sectional study

IntroductionCervical cancer continues to pose a major public health challenge in low-income countries. Cervical cancer screening programs enable early detection and effectively reduce the incidence of cervical cancer as well as late-stage diagnosis and mortality. However, screening uptake remains suboptimal in Uganda. This study assessed correlates of intention to screen for cervical cancer among women in the Kyotera district of Central Uganda.MethodsWe analyzed cross-sectional data collected to determine the effectiveness of community audio towers (CATs) as a modality of health communication to support cervical cancer prevention. Women (n = 430) aged 21–60 years without a prior history of cervical cancer screening were surveyed about demographics, sources of health information and cervical cancer screening intentions in 2020. We used generalized linear modelling with modified Poisson regression and backwards variable elimination to identify adjusted prevalence ratios and 95% confidence intervals (CI) to determine factors associated with intention to screen for cervical cancer.ResultsHalf (50.2%) of the participants had intentions to screen for cervical cancer within twelve months and 26.5% had moderate knowledge about cervical cancer. Nearly half (46.0%) considered themselves at risk of cervical cancer. Compared to residents who primarily received their health information from social media and radio, participants who received health information primarily from CATs (aPR:0.64, 95% CI:0.52–0.80, p < 0.001) and TV (aPR:0.52, 95% CI:0.34–0.82, p = 0.005) had a lower prevalence of intention to screen for cervical cancer. The prevalence of intentions to screen for cervical cancer in twelve months was higher among those resided in town councils (aPR:1.44, 95% CI:1.12–1.86, p = 0.004) compared to rural areas, and higher among those who considered themselves to be at risk of cervical cancer (aPR:1.74, 95% CI:1.28–2.36, p < 0.001) compared to those who did not.ConclusionsWe found suboptimal prevalence of intentions to screen for cervical cancer among women in central Uganda. Additional research and implementation projects are needed to increase cervical cancer screening. Targeting risk perceptions and behavioral approaches to increase intentions could be effective in future intervention work. Based on urban-rural differences, additional work is needed to support equitable sharing of information to support cancer prevention messaging; CATs and TV may best help reach those with lower intentions to screen based on our research.

The association of demographic and socioeconomic variables with cancer screening participation: A national cross-sectional study of three cancer screening programs in Denmark

ObjectiveTo analyze the demographic and socioeconomic determinants of non-participation in cervical, colorectal and breast cancer screening programs in Denmark. Study design and settingWe conducted a cross-sectional study involving all women aged 53–65 years residing in Denmark on March 31, 2018, utilizing comprehensive individual data from population registries. Logistic regression models were employed to assess associations between demographic and socioeconomic factors and non-participation compared with participating in one, two, and three cancer screening programs, presenting odds ratios (ORs) with 95 % confidence intervals (CIs). Both unadjusted and adjusted models were applied for each level of screening participation. ResultsSignificant associations with non-participation in the three cancer screening programs were observed across all demographic and socioeconomic covariates considered. Women with low incomes demonstrated the highest likelihood of non-participation (none vs. three programs attended, OR: 2.95, 95 % CI: 2.82–3.08). Similarly, increased odds of non-participation were noted among immigrants (Western immigrants: OR: 2.08, 95 % CI: 1.96–2.21; non-Western immigrants OR 1.26 95 % CI: 1.20–1.32), women living alone (OR: 2.08, 95 % CI: 2.02–2.14), women outside the labor force (OR: 1.92, 95 % CI: 1.86–1.99), and women with lower educational levels (OR: 1.44, 95 % CI: 1.39–1.50) in the model comparing non-participation to participating in three screening programs. A progressive intensification of the association with non-participation was noted with each incremental increase in screening participation (from one to two to three programs). ConclusionsDemographic and socioeconomic variables are significantly associated with non-participation in all three Danish cancer screening programs, particularly affecting women from vulnerable demographic and socioeconomic backgrounds. Future research should prioritize strategies to enhance participation within this subgroup, aiming to alleviate social inequities in cancer screening.

Human Papilloma Virus Vaccination and Cervical Screening in the Italian Regions: An Overview of the Current State of the Art.

Human Papilloma Virus (HPV) infection and HPV-related cancers can be prevented through vaccinations and mass cervical screening programmes. The Ministry of Health in Italy provides recommendations on primary and secondary prevention of HPV-related diseases, but the 19 Italian regions and 2 autonomous provinces have organisational and decision-making autonomy, with differences in the strategies for offering prevention. The aim of this study is to describe the HPV vaccination and cervical screening offered in all Italian regions. Regional official documents up until 31 December 2021 were first identified. Subsequently, primary and secondary prevention experts from each region were interviewed to validate the previously collected data. The National Immunisation Plan (NIP) 2017-2019 recommends HPV vaccination from the age of 11 for both sexes, with a coverage target of 95%. HPV vaccination is offered free of charge or co-payment. All regions have screening programmes for cervical cancer, using PAP or HPV-DNA tests every three to five years. All regions have an electronic registry for vaccination and screening status. All regions have developed awareness-raising campaigns. It is important to harmonise regional policies with the implementation of information systems integration. The collected data could enhance both regional and national public health initiatives, bolstering the resilience of vaccination programs.

Immunization and Screening Methods for Cervical Carcinoma in Developing Nations: A Detailed Review

Objective: Cervical cancer remains a significant public health challenge in developing countries, disproportionately affecting women in these regions due to limited access to effective screening and vaccination programs. This review synthesizes the current literature on the implementation strategies, effectiveness, and challenges of cervical cancer screening and Human Papillomavirus (HPV) vaccination programs in developing countries, aiming to highlight successful models and identify gaps in current practices. Screening, for cervical cancer in developing countries faces numerous obstacles, including logistical challenges, lack of awareness, and insufficient healthcare infrastructure. Despite these hurdles, strategies such as single-visit approaches, leveraging low-cost HPV DNA testing, and utilizing mobile health units have shown promise in increasing screening coverage and early detection rates. The prerequisites for effective screening highlighted include affordability, cultural acceptability, and the ability to implement large-scale screening with limited resources. HPV vaccination presents a primary prevention measure with the potential to significantly reduce the incidence of cervical cancer. However, vaccination programs in developing countries encounter challenges in vaccine procurement, distribution, and achieving high coverage rates among the target population. Innovations in vaccine delivery, education campaigns to raise awareness, and partnerships with international health organizations are crucial for overcoming these barriers.This comprehensive review underscores the need for a multifaceted approach to cervical cancer prevention in developing countries, encompassing improvements in screening and vaccination strategies, health system strengthening, community engagement, and international collaboration. By learning from successful models and addressing identified gaps, there is a significant opportunity to reduce the burden of cervical cancer in these regions and move closer to achieving global health equity.

Characteristics and utility of high-resolution optical coherence microscopy images of endocervical canal lesions.

To investigate optical coherence microscopy (OCM) imaging features and the application value of these high-resolution images for identifying endocervical canal lesions (ECLs), which is a clinical dilemma in cervical cancer screening programs. In total, 520 OCM images were obtained by scanning the cervical canal lesions with an ultra-high-resolution OCM system (204 specimens from 73 patients). The OCM morphologic characteristics of ECLs were observed and summarized, and then 3 researchers performed a diagnostic test of OCM images of cervical canal lesions. The accuracy, sensitivity, specificity, positive predictive value, negative predictive value, 95% confidence interval of each parameter, and interinvestigator agreement (κ) were calculated. Normal endocervix, cysts, squamous metaplasia, high-grade squamous intraepithelial lesions involving glands, and invasive carcinoma had distinct OCM characteristics, which correlated well with corresponding H&E histologic sections. The accuracy, sensitivity, and specificity of the 3 researchers were 90.6%, 89.3% (95% CI, 86.5%-91.7%) and 91.6% (95% CI, 89.2%-93.5%), respectively. The positive predictive value was 90.1% (95% CI, 87.3%-92.4%), and the negative predictive value was 90.9% (95% CI, 88.5%-92.9%), with almost perfect agreement (κ = 0.874). The application of the OCM system in cervical canal lesions is feasible and could help improve detection of occult ECLs in cervical cancer screening programs. This study lays the foundation for further research on OCM in cervical canal lesions in vivo, which also has a potential impact on projecting pathologic evaluation beyond what is currently possible, perhaps globally.

Cervical Sampling and Preparation of Pap Smear

Since the middle of the 20th century, the cervical cancer screening test has been a widely used method for identifying precursor cells in cancer cases. The disease may be eradicated if premalignant cells are found early enough. According to studies, pap smear-based screening programs for cervical cancer can dramatically reduce the number of fatalities worldwide attributable to cervical cancer. Understanding the female reproductive system is crucial for the efficient and representative collection of cervical samples, and a methodical and cautious approach to sample collection is required. Following directions and using the appropriate instruments for collecting specimens are crucial for producing high-quality results. In order to help providers to better comprehend the subject, this work sheds light on the procedure and method of cervical sample collection.

Preliminary outcomes of the Cervical Cancer Screening Program of Northern Portugal: A snapshot

BackgroundCervical cancer screening remains an essential preventive tool worldwide. First line high-risk Human Papillomavirus (HrHPV) genotyping became gold standard for cervical cancer screening, and has been adopted by several countries, including Portugal. Herein, we aimed to assess the early outcomes of the regional Cervical Cancer Screening Program of Northern Portugal. MethodsThe analysis of a representative set of cases evaluated during a one-month period (January 2020), with adequate follow-up was performed. Descriptive analysis was performed. ResultsOverall, 7278 samples were received, of which 15.2% were HrHPV positive, most of these disclosing a negative result in subsequent liquid-based cytology. Nearly half of the HrHPV-positive women were referred to colposcopy. Within this group, HPV16/18+ cases depicted the higher frequency of high-grade squamous intraepithelial lesion (HSIL) or worse, compared with abnormal cytology or persistent HrHPV infection. Among women with non-HPV16/18 HrHPV infection and negative cytology, which are eligible for repeat sampling in one year, 65% were re-tested. Importantly, nearly half of these cleared HrHPV infection. Furthermore, referral to colposcopy due to HPV16/18 infection and/or abnormal cytology results were associated with > 40% risk for HSIL or worse lesion. ConclusionsOur study confirmed the reliability and effectiveness of first line HrHPV genotyping in the Cervical Cancer Screening Program of Northern Portugal. Nonetheless, it also raised concerns about excessive referral to colposcopy, with the inherent human and financial costs. Thus, further improvement and optimization are key to ensure the sustainability of the program.

Lessons From the Design and Rollout of an Electronic Medical Record System for Cervical Cancer Screening in Rwanda.

In its commitment to delivering comprehensive women's cancer early detection services, the Rwanda Ministry of Health rolled out a new cervical cancer screening program. The paper-based medical record system that tracked clients at different points in the continuum of cervical cancer care had challenges with storing data, accessing client information for follow-up visits, and fragmenting information on individual clients. To support the rollout of the new cervical cancer screening program, a new electronic medical record system was designed and implemented to ensure clients were followed along the complete continuum of care. We document the development and implementation of the electronic medical record system and highlight challenges and lessons learned during implementation. Implementation took a participatory approach to ensure that the electronic medical record system was efficient in tracking clients along the continuum of care. At every stage, a wide range of stakeholders were engaged, including clinicians, program managers, and software developers. Health facility visits and conversations were conducted with health care providers and data managers to review the existing system and ensure that the design and development of the electronic record system were suitable for the context in which it would be used. Cervical cancer screening sites are currently using the electronic medical record system to document client information and track women along the continuum of care to reduce loss to follow-up. The system has been rolled out to all newly activated screening sites as part of national scale-up. Planning, collaboration, and adaptability were the key factors in this system's successful rollout and should be the foundation of future data systems development.

Cervical microbiota dysbiosis associated with high-risk Human Papillomavirus infection.

High-risk Human Papillomavirus (HR-HPV) genotypes, specifically HPV16 and HPV18, pose a significant risk for the development of cervical intraepithelial neoplasia and cervical cancer. In the multifaceted cervical microenvironment, consisting of immune cells and diverse microbiota, Lactobacillus emerges as a pivotal factor, wielding significant influence in both stabilizing and disrupting the microbiome of the reproductive tract. To analyze the distinction between the cervical microbiota and Lactobacillus-dominant/non-dominant status of HR-HPV and non-infected healthy women, sixty-nine cervical swab samples were analyzed, included 44 with HR-HPV infection and healthy controls. All samples were recruited from Human Papillomavirus-based cervical cancer screening program and subjected to 16s rRNA sequencing analysis. Alpha and beta diversity analyses reveal no significant differences in the cervical microbiota of HR-HPV-infected women, including 16 and 18 HPV genotypes, and those with squamous intraepithelial lesion (SIL), compared to a control group. In this study we identified significantly lower abundance of Lactobacillus mucosae in women with HR-HPV infection compared to the control group. Furthermore, changes in bacterial diversity were noted in Lactobacillus non-dominant (LND) samples compared to Lactobacillus-dominant (LD) in both HR-HPV-infected and control groups. LND samples in HR-HPV-infected women exhibited a cervical dysbiotic state, characterized by Lactobacillus deficiency. In turn, the LD HR-HPV group showed an overrepresentation of Lactobacillus helveticus. In summary, our study highlighted the distinctive roles of L. mucosae and L. helveticus in HR-HPV infections, signaling a need for further research to demonstrate potential clinical implications of cervical microbiota dysbiosis.

Feasibility and applicability of self-sampling based online cervical cancer screening: findings from the China online cervical cancer screening trial

ObjectiveThis study aims to evaluate the feasibility and applicability of an online cervical cancer screening program using a website as the public platform and self-collected HPV testing as the primary screening method.MethodsA website (mcareu.com) was developed to facilitate the online cervical cancer screening program by Peking University Shenzhen Hospital (PUSH). Women in Shenzhen could register for participation on the website by providing essential demographic data. Sampling kits and specimens were delivered through regular logistics. Eligible women collected vaginal samples by themselves using the provided kits and in referring of the graphic guidance. The specimens were tested for HPV at PUSH or a reference lab, and the results were accessible on the website through participants' personal accounts. Participants who tested positive for high-risk HPV were scheduled for colposcopy and biopsies. The demographic and social background data of the eligible participants were analyzed to evaluate the feasibility and applicability of the online screening approach.ResultsA total of 1712 applicants registered for participation, with 99.9% (1710/1712) completing registration with full data. The analysis included 1560 applicants aged 30–59, with an average age of 41.1 (± 7.6) years. Among them, 83.3% (1299/1560) provided self-collected samples for testing. Age-group analysis revealed an overall sample provision rate (SPR) exceeded 80% in all age groups. A significant difference in SPR was observed only between the 30–34 and 45–49 age groups (p < 0.05), while no significant differences were found among other age groups. 99.7% of the samples were tested qualified, and there was no significant difference in sampling failure rate among age groups. Analysis of demographic and social elements showed no significant impact on the rates of sample provision among groups in most of the social elements but the medical insurance and the monthly family-incomes.ConclusionThe findings demonstrate that online cervical cancer screening is reliable for self-registration, self-sampling, and self-ordering for specimen transportation. It is suitable for women of all ages needing to be screened, irrespective of social elements, and effectively facilitates screening for women with limited access to medical resources. Therefore, online screening holds promise as an effective approach to increase screening coverage.

Understanding of cervical cancer, acceptability of HPV self-collection, and prevalence of HPV in a semi-urban setting in Bangladesh.

Human Papillomavirus (HPV) self-sampling has been implemented successfully as an alternative to traditional forms of cervical cancer screening in low-resource settings. Through Bangladesh's current national cervical cancer screening program, only about 10% of the at-risk population is reached. Thus, Bangladesh is an ideal setting to consider HPV self-sampling to improve cervical cancer prevention efforts. However, the feasibility and acceptability of HPV self-sampling has not been evaluated in Bangladesh. We aimed to understand levels of HPV and cervical cancer knowledge and to evaluate the feasibility and acceptability of HPV self-sampling for cervical cancer screening in a semi-urban Bangladeshi community. Participants were recruited from a local clinic; 164 women completed a cross-sectional questionnaire about attitudes towards screening, and cervical cancer and HPV risk factor knowledge, and provided self-collected cervical samples for high-risk HPV testing. Of the participants, 4.3% tested positive for high-risk HPV and were referred for appropriate follow-up care. Nearly all participants had heard of cervical cancer, though specific knowledge was quite low. Self-sampling for high-risk HPV testing had high rates of acceptability, high rates of convenience, and very little discomfort and embarrassment reported in this study population, making implementing HPV self-sampling as a form of cervical cancer screening in Bangladesh appear feasible.

Effectiveness of self-sampling human papillomavirus test on precancer detection and screening uptake in Japan: The ACCESS randomized controlled trial.

Japan is lagging in cervical cancer prevention. The effectiveness of a self-sampling human papillomavirus (HPV) test, a possible measure to overcome this situation, has not yet been evaluated. A randomized controlled trial was performed to evaluate the effectiveness of a self-sampling HPV test on detection of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and screening uptake. Women between 30 and 58 years old who did not participate in the cervical cancer screening program for ≥3 years were eligible and assigned to the intervention group (cytology or self-sampling HPV test) or control group (cytology). Participants assigned to the intervention group were sent a self-sampling kit according to their ordering (opt-in strategy). A total of 7337 and 7772 women were assigned to the intervention and control groups, respectively. Screening uptake in the intervention group was significantly higher than that in the control group (20.0% vs. 6.4%; risk ratio: 3.10; 95% confidence interval [CI]: 2.82, 3.42). The compliance rate with cytology triage for HPV-positive women was 46.8% (95% CI: 35.5%, 58.4%). CIN2+ was detected in five and four participants in the intervention and control groups, respectively; there was no difference for intention-to-screen analysis (risk ratio: 1.32; 95% CI: 0.36, 4.93). Self-sampling of HPV test increased screening uptake; however, no difference was observed in the detection of CIN2+, probably due to the low compliance rate for cytology triage in HPV-positive women. Efforts to increase cytology triage are essential to maximize precancer detections.

Prevalence of high-risk HPV and cervical dysplasia in IUD users and controls: a cross sectional study

Objective To examine the prevalence of infections with high-risk human papillomavirus (HPV) and cervical dysplasia, and the clearance rate of HPV infections, in users of different kinds of intrauterine devices (IUDs) and other contraceptive methods. Methods A cross-sectional register-based study including 16,181 women aged 30–49 years participating in the screening programme for cervical cancer in a Swedish County in 2017–2018. Data on contraception from screening records was paired with the HPV test results, cytological and histological follow-up tests and subsequent HPV test. Results There was no difference in the risk of being HPV positive, or histological HSIL+, between users of copper-containing IUDs and women with no reported use of contraception. Use of levonorgestrel intrauterine system and hormonal contraception were associated with higher odds for HPV infection in age-adjusted models (aOR 1.21; 95% CI 1.04–1.41, and aOR 1.41; 95% CI 1.22–1.63, respectively) and for HSIL+ (aOR 1.45; 95% CI 1.02–2.06, and aOR 1.56; 95% CI 1.13–2.16, respectively). No significant differences were found in HPV clearance rates. Conclusions Reported use of levonorgestrel intrauterine system and hormonal contraception, but not use of copper IUD, was associated with a higher prevalence of HPV infections and histological HSIL + compared to no reported use of contraception.

Implementation of new technologies designed to improve cervical cancer screening and completion of care in low-resource settings: a case study from the Proyecto Precancer

BackgroundThis case study details the experience of the Proyecto Precancer in applying the Integrative Systems Praxis for Implementation Research (INSPIRE) methodology to guide the co-development, planning, implementation, adoption, and sustainment of new technologies and screening practices in a cervical cancer screening and management (CCSM) program in the Peruvian Amazon. We briefly describe the theoretical grounding of the INSPIRE framework, the phases of the INSPIRE process, the activities within each phase, and the RE-AIM outcomes used to evaluate program outcomes.MethodsProyecto Precancer iteratively engaged over 90 stakeholders in the Micro Red Iquitos Sur (MRIS) health network in the Amazonian region of Loreto, Perú, through the INSPIRE phases. INSPIRE is an integrative research methodology grounded in systems thinking, participatory action research, and implementation science frameworks such as the Consolidated Framework for Implementation Research. An interrupted time-series design with a mixed-methods RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) evaluation framework was used to examine the adoption of human papillomavirus (HPV) testing (including self-sampling), with direct treatment after visual inspection with portable thermal ablation, at the primary level.ResultsThis approach, blending participatory action research, implementation science, and systems-thinking, led to rapid adoption and successful implementation of the new cervical cancer screening and management program within 6 months, using an HPV-based screen-and-treat strategy across 17 health facilities in one of the largest public health networks of the Peruvian Amazon. Monitoring and evaluation data revealed that, within 6 months, the MRIS had surpassed their monthly screening goals, tripling their original screening rate, with approximately 70% of HPV-positive women reaching a completion of care endpoint, compared with around 30% prior to the new CCSM strategy.ConclusionsProyecto Precancer facilitated the adoption and sustainment of HPV testing with subsequent treatment of HPV-positive women (after visual inspection) using portable thermal ablation at the primary level. This was accompanied by the de-implementation of existing visual inspection-based screening strategies and colposcopy for routine precancer triage at the hospital level. This case study highlights how implementation science approaches were used to guide the sustained adoption of a new screen-and-treat strategy in the Peruvian Amazon, while facilitating de-implementation of older screening practices.

Factors influencing cervical cancer screening uptake among the women in Maesot, Tak province, Thailand

Background: Cervical cancer is one of the most significant public health issues in Thailand. The number of women who have had cervical cancer screenings has increased over time; however, if major obstacles are not addressed, it will become challenging to maintain this success. Objectives: This study aimed to identify the magnitude and factors influencing cervical cancer screening uptake among women in Maesot, Tak Province, Thailand. Methods: This cross-sectional study was conducted in Maesot, Thailand. A structured questionnaire was used. Descriptive statistics and multiple logistic regression were used to determine the magnitude of the cervical cancer screening uptake and associated factors. The association was described with an Adjusted Odds Ratio (AOR) and 95% Confidence Interval (95% CI) at the statistically significant level of p-value &lt; 0.05. Results: Of the total 422 women, the average age was 38.82 ±8.46 years. Nearly one-fourth of the respondents were Thai nationals. Almost 70% of respondents were married, and 80% were employed. About one-third of respondents had a high school level of education. The magnitude of Cervical Cancer Screening Uptake (CCSU) was 13.27% (95% CI: 10.34-16.86). Age ≥ 40 years (AOR=2.15, 95%CI: 1.05-4.40), Christian and having others religion (AOR=2.19,95% CI:1.08-4.44), married between 26 years to 43 years (AOR= 2.93, 95%CI: 1.45-5.93), having good knowledge of cervical cancer (AOR= 4.70, 95%CI: 2.22-9.72), and having good knowledge of cervical cancer screening program (AOR= 6.58, 95%CI: 2.82-17.77) were significant predictors of cervical cancer screening. Conclusion: Cervical cancer screening among women in Maesot is lower than that of national coverage of Thailand. Determining factors for the decision to undergo cervical cancer screening uptake include age, religion, age of marriage, knowledge of cervical cancer and knowledge of cervical cancer screening program. To improve uptake, structured screening programs need to be implemented in collaboration with national partners and institutions to decrease the incidence of cervical cancer in Thailand.

IJCM_229A: A Community-based screening programme for oral, breast, and cervical cancer in the rural area of Dakshin Kannada

Background: Karnataka recorded 87304 new cancer cases in the year 2021. Breast, lip and oral cavity, cervix were the top cancer sites amongst all sexes and are preventable. Despite the nation-wide launch of Population-based screening (PBS) in 2016, the reported coverage of individuals who were screened for these three cancers in Dakshin Kannada was 0.4% (NFHS-5). The study introduces on-site screening for oral and breast cancer in the community. Objectives: To estimate the proportion of pre-cancerous lesions of oral, breast, and cervical cancer, through community-based screening in adults aged 18 to 65 years, in the catchment area of a medical college in Dakshina Kannada Methodology: This observational study was conducted among all persons aged 18 to 65years, residing in the rural catchment area of a medical college in Mangalore taluk of Dakshina Kannada and consenting for the study. Pregnant women and persons with prior diagnosis of oral, breast or cervical cancer were excluded. Two-stage cluster sampling was used to enrol an estimated sample of 1120 beneficiaries. The study comprised of house-to-house survey, cancer awareness sessions, and community-based screening. Screening tests included Oral visual examination, clinical breast examination, iBreast examination (iBE; electronic palpation by ibreast device), and Pap smear tests. Participants who screened positive were referred for diagnostic tests and management. Results: The study was completed with survey of 556 households, 3 cancer awareness sessions, and screening of 525 beneficiaries (325 females and 200 males) for oral, breast, and cervical cancer. Three participants screened positive for oral cancer, and one participant for breast cancer, who were referred for management to tertiary care hospital attached to the medical college. 25% of female participants underwent cervical cancer screening, with no one detected with pre-cancerous lesions. Conclusion: A combination of house-to-house and camp-based approaches along with awareness sessions results in improved coverage of PBS in the community.

Factors Associated with Abnormal Mammogram Results Among Low-Income Uninsured Populations in Medically Underserved And Rural Texas Regions.

This study investigated the potential associations between neighborhood characteristics, rurality, ethnicity/race, and breast cancer screening outcomes in designated Health Professional Shortage Areas in Central Texas. Limited access to preventive medical care can impact screening rates and outcomes. Previous research on the effects of factors such as rurality, neighborhood socioeconomic status, and education level on cancer prevention behaviors has yielded inconsistent results. We analyzed data from a state-funded breast and cervical cancer screening programs for disadvantaged and medically underserved individuals. A mixed-effects logistic regression model was used to assess the impact of residency characteristics (rurality, educational attainment, unemployment, and poverty) on abnormal breast cancer screening outcomes, with individual level (age, ethnicity, race, and education) as control variables. During the studied time, there were 1,139 women screened and 134 abnormal mammograms found. Residency characteristics were not significantly associated with abnormal mammography outcomes at 0.05. However, individual factors are strongly associated with abnormal screening results. Non-Hispanic or Latino white women had increased odds of abnormal clinical outcomes compared with Hispanic or Latino women (OR = 2.03, CI 1.25-3.28; p = 0.004). Additionally, women residing in counties with more than 30% of the population completing college had increased odds of abnormal mammogram outcomes compared with counties with less than 15% college attainment (OR = 2.89, CI 0.99-8.38; p = 0.051). This study found a significant correlation between area-level educational characteristics and abnormal mammography outcomes. Future research should explore the contextual risk factors influencing breast cancer occurrence and develop targeted interventions for this population.

The Acceptability and Feasibility of Self-Collected HPV Testing for Cervical Cancer Screening Among Black and Latinx Women in Chicago: Perspectives from the Community.

Cervical cancer disproportionally affects Black and Latinx women in Chicago. Black and Latinx women have a higher incidence of cervical cancer diagnosis and lower rates of cervical cancer screening than non-Latinx White women. Self-collected high-risk human papillomavirus (HPV) testing has been proposed as a method to address these barriers to screening and prevent cervical cancer. This study aimed to understand the feasibility and acceptability of self-collected HPV testing as a novel approach to address barriers to cervical cancer screening for Black and Latinx women in Chicago. Semistructured interviews with 17 Black and Latinx community members of the greater Chicago area were conducted. Thematic analysis using inductive and deductive coding was completed. Findings from qualitative interviews indicate strong support for self-collected HPV testing among community members.
