Abstract
Cervical cancer is the first cancer deemed amenable to elimination through prevention, and thus lessons from the epidemiology and prevention of this cancer type can provide information on strategies to manage other cancers. Infection with the human papillomavirus (HPV) causes virtually all cervical cancers, and an important proportion of oropharyngeal, anal and genital cancers. Whereas 20th century prevention efforts were dominated by cytology-based screening, the present and future of HPV-associated cancer prevention relies mostly on HPV vaccination and molecular screening tests. In this Review, we provide an overview of the epidemiology of HPV-associated cancers, their disease burden, how past and contemporary preventive interventions have shaped their incidence and mortality, and the potential for elimination. We particularly focus on the cofactors that could have the greatest effect on prevention efforts, such as parity and human immunodeficiency virus infection, as well as on social determinants of health. Given that the incidence of and mortality from HPV-associated cancers remain strongly associated with the socioeconomic status of individuals and the human development index of countries, elimination efforts are unlikely to succeed unless prevention efforts focus on health equity, with a commitment to both primary and secondary prevention.

J Racial Ethn Health Disparities 2024:10.1007/s40615-024-01963-9. [PMID: 38472631 DOI: 10.1007/s40615-024-01963-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 02/20/2024] [Accepted: 02/21/2024] [Indexed: 03/14/2024]
Abstract
BACKGROUND Ethnic minority women are less likely to participate in cervical cancer uteri (CCU) screening compared to native women. Human Papillomavirus (HPV) self-sampling kits for CCU screening may be a potential strategy to increase participation. This study aimed to explore views and attitudes on four different types of self-sampling kits (two brushes, a first-void urine device, and a menstrual blood device) among non-Western ethnic minority women living in Denmark. METHODS The study was a social science single case study based on focus group interviews with 30 women aged 32-54 with non-Western background from a deprived area. A phenomenological approach was applied to describe the phenomenon "self-sampling" as seen from the women's lifeworlds. The interviews were transcribed verbatim and analysed using systematic text condensation. RESULTS The women expressed significant interest in the possibility of using HPV self-sampling kits as an alternative to being screened by their general practitioner. They were particularly motivated to use the non-invasive self-sampling kits for CCU screening as they were deemed suitable for addressing cultural beliefs related to their bodies and virginity. The women expressed interest in the use of the invasive self-sampling kits but were cautious, primarily due to lack of confidence in correctly performing self-sampling with a brush and due to cultural beliefs. CONCLUSION The use of non-invasive self-sampling kits, such as a first-void urine collection device and menstrual blood pad, represents a promising solution to overcome cultural barriers and promote greater equality in CCU screening participation among non-Western ethnic minority women.

Prev Med 2024; 180:107888. [PMID: 38325609 DOI: 10.1016/j.ypmed.2024.107888] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Revised: 01/25/2024] [Accepted: 02/04/2024] [Indexed: 02/09/2024]
Abstract
OBJECTIVE Denmark went through various COVID-19 pandemic restrictions including periodic lockdowns from March 2020 to January 2022. All cancer screening programs were kept operational, yet access to clinicians for cervical screening was at times limited. We assessed the impact of the pandemic on cervical cancer screening activity in the Capital Region of Denmark. METHODS Cervical screening activity was defined as regular screening by invitation, opportunistic screening, and screening participation by HPV self-sampling. Activity was monitored during and post-pandemic and compared relatively to a 3-year pre-pandemic reference. RESULTS AND CONCLUSIONS The activity of cervical cancer screening was initially affected by the pandemic lockdowns, but increased activity during summer 2020 partly compensated this effect. Regular screening activity decreased 8.4% in 2020 and returned to pre-pandemic levels in 2021. During 2022 restrictions were removed and the decrease in activity was recorded to be 2.3%. Opportunistic screening activity was reduced by 14.3% in 2020 and 12.6% in 2021. A continued post-pandemic opportunistic screening activity reduction of 18.5% was observed, possibly related to changed patterns of primary health care use introduced during the pandemic. Screening by HPV self-sampling increased from 17.1% in the pre-pandemic period to 21.2% during the pandemic. Significantly more acceptance was recorded amongst older women (p < 0.0001). This increase mirrors the decrease in total clinician collected sample activity during the pandemic, where an increased reduction by age was observed. Post-pandemic HPV self-sampling participation decreased to 12.8%, possible reflecting a temporarily changed composition and motivation in the group of women invited for self-sampling.

Abstract
BACKGROUND For cervical cancer (CC), the implementation of preventive strategies has the potential to make cervical cancer occurrence and death largely avoidable. To better understand the factors possibly responsible for cervical cancer, we aimed to examine possible differences in age and social parameters as well as screening status between women with low- or high-stage cervical cancer and matched controls. METHODS Through the Danish Cancer Registry (DCR), women diagnosed with cervical cancer in Denmark between 1987 and 2016 were included. These were age- and residence-matched in a 1:5 ratio with controls from the general female population. The study population was sub grouped into a low-stage subpopulation with women with early-stage cervical cancer and matched controls and a high-stage subpopulation with women with late-stage cervical cancer and matched controls. Age and social parameters were compared within the subpopulations as well as between low- and high-stage cases. For part of the study population, screening attendance was examined to compare differences in adherence. RESULTS Overall, we found that the risk of cervical cancer is significantly increased in socially disadvantaged women and not least non-attenders in screening. Interestingly, the high-stage subpopulation was significantly older than the low-stage subpopulation (p < 0.001), and when examining the impact of age further, we found that for cervical cancer cases, the risk of having low-stage disease decreases significantly with increasing age, whereas the risk of having high-stage disease increases significantly with increasing age. In the screening cohort, significantly less cases than controls were attenders in screening with the most pronounced differences seen in the old subpopulation (women aged 50-64 years) and in the high-stage subpopulation (p-values all < 0.001). Interestingly, when examining the risk of CC for attenders and non-attenders, we demonstrated that many social parameters continue to influence the risk of cervical cancer, even in women attending screening. CONCLUSIONS Older women, socially disadvantaged women, and non-attenders in screening are particularly vulnerable in terms of developing cervical cancer, especially high-stage disease. Therefore, improvements in the participating rate in screening as well as a revision of the current screening guidelines are needed.

Abstract
The purpose of this paper is to provide evidence-based guidance on the management of a positive human papilloma virus (HPV) test and to provide guidance around screening and HPV testing for specific patient populations. The guideline was developed by a working group in collaboration with the Gynecologic Oncology Society of Canada (GOC), Society of Colposcopists of Canada (SCC), and the Canadian Partnership Against Cancer. The literature informing these guidelines was obtained through a systematic review of relevant literature by a multi-step search process led by an information specialist. The literature was reviewed up to July 2021 with manual searches of relevant national guidelines and more recent publications. The quality of the evidence and strength of recommendations were developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. The intended users of this guideline include primary care providers, gynecologists, colposcopists, screening programs, and healthcare facilities. The implementation of the recommendations will ensure an optimum implementation of HPV testing with a focus on the management of positive results. Recommendations for appropriate care for underserved and marginalized groups are made.

Abstract
BACKGROUND This study aimed to investigate the status of cervical cancer screening (CCS) implementation in Europe by investigating national or regional policies towards broadening coverage of CCS amongst vulnerable subgroups of the population at high risk for CC. METHODS A web-based survey was conducted between September 2021 and February 2022 with CCS programme managers and experts to identify and rank six population subgroups at high risk considered most vulnerable to CC and to map existing policies that addressed the coverage of CCS towards population sub-groups at risk. RESULTS A total of 31 responses were received from experts covering 22 European countries. The results of this survey suggest that whilst many countries identify lower coverage of CCS amongst population subgroups at high risk of CC as a public health problem, few countries have developed dedicated policies towards broadening coverage among these subgroups. The six countries who reported having done so were concentrated in the Northern or Western European regions, suggesting the existence of geographical disparities within the continent. A key challenge in this respect is the difficulty to categorize subgroups of the target population; many individuals are burdened by intersectionality thereby resting in multiple categories, which may hinder the effectiveness of interventions targeted to reach specific subgroups. CONCLUSION A greater clarity on the conceptualization of vulnerability can help countries to develop and subsequently implement strategies to increase coverage to subgroups of the target population currently underserved with regards to CCS.

Abstract
OBJECTIVE To review our national cervical cancer screening program using existing Ministry of Public Health primary healthcare centers (PHCs) and report the impact of women's knowledge, attitude, behavior, and practices on screening uptake and outcome. METHODS A cross-sectional study on cervical cancer screening offered to sexually active Lebanese women aged 21 years and above visiting PHCs. Exclusions were history of complete hysterectomy, gynecologic cancers, and current pregnancy. Data were collected through a questionnaire and conventional cervical smear performed by trained healthcare providers and sent to one centralized cytopathology laboratory. RESULTS Of 12 273 eligible women, 1.7% had an abnormal cervical smear test including 161 atypical squamous cells (ASC) of undetermined significance, 6 atypical glandular cells of undetermined significance, 16 low-grade squamous intraepithelial lesion (SIL), 17 ASC-cannot rule out high-grade SIL, 11 high-grade SIL, and one invasive carcinoma. Knowledge and attitudes significantly affected participation in screening; women lacking awareness had rarely undergone a cervical smear. CONCLUSION In Lebanon, cytology-based cervical cancer screening is feasible within the PHCs. Positive screen incidence was low. Despite previous campaigns, a low level of knowledge persists, and affects women's com with the screening guidelines. Advocacy and awareness activities by key healthcare providers may help to improve participation.

Abstract
BACKGROUND Human papillomavirus (HPV) testing on self-samples represents a great opportunity to increase cervical cancer screening uptake among under-screened women. METHODS A systematic review and meta-analysis on randomised controlled trials (RCTs) were performed to update the evidence on the efficacy of strategies for offering self-sampling kits for HPV testing compared to conventional invitations and to compare different self-sampling invitation scenarios. Four experimental invitational scenarios were considered. Women in the control group were invited for screening according to existing practice: collection of a cervical specimen by a healthcare professional. Random-effects models were used to pool proportions, relative participation rates and absolute participation differences. RESULTS Thirty-three trials were included. In the intention-to-treat analysis, all self-sampling invitation scenarios were more effective in reaching under-screened women compared to controls. Pooled participation difference (PD) and 95% confidence interval (CI) for experimental vs. control was 13.2% (95% CI = 11.0-15.3%) for mail-to-all, 4.4% (95% CI = 1.2-7.6%) for opt-in, 39.1% (95% CI = 8.4-69.9%) for community mobilisation & outreach and 28.1% (23.5-32.7%) for offer at healthcare service. PD for the comparison opt-in vs. mail-to-all, assessed in nine trials, was -8.2% (95% CI = -10.8 to -5.7%). DISCUSSION Overall, screening participation was higher among women invited for self-sampling compared to control, regardless of the invitation strategy used. Opt-in strategies were less effective than send-to-all strategies.

Abstract
Cervical cancer is the fourth most common malignancy in females worldwide, and a leading cause of death in the United Kingdom (UK). The human papillomavirus (HPV) is the strongest risk factor for developing cervical intraepithelial neoplasia and cancer. Across the UK, the national HPV immunisation programme, introduced in 2008, has been successful in protecting against HPV-related infections. Furthermore, the National Health Service (NHS) implemented the cytology-based cervical cancer screening service to all females aged 25 to 64, which has observed a decline in cervical cancer incidence. In the UK, there has been an overall decline in age-appropriate coverage since April 2010. In 2019, the COVID-19 pandemic disrupted NHS cancer screening and immunisation programmes, leading to a 6.8% decreased uptake of cervical cancer screening from the previous year. Engagement with screening has also been associated with social deprivation. In England, incidence rates of cervical cancer were reported to be 65% higher in the most deprived areas compared to the least, with lifestyle factors such as cigarette consumption contributing to 21% of cervical cancer cases. In this article, we provide an update on the epidemiology of cervical cancer, and HPV pathogenesis and transmission, along with the current prevention programmes within the NHS.

The SWIM study: Ethnic minority women's ideas and preferences for a tailored intervention to promote national cancer screening programmes-A qualitative interview study. Health Expect 2021; 24:1692-1700. [PMID: 34232543 PMCID: PMC8483185 DOI: 10.1111/hex.13309] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Revised: 06/08/2021] [Accepted: 06/19/2021] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Ethnic minority women from non-Western countries are less likely than the native women to participate in screening programmes for cervical cancer, breast cancer and colorectal cancer. This social inequality can result in loss of possibility for prevention, delayed diagnosis and treatment and, ultimately, lower chance of survival. Developing a tailored intervention might be the solution to reduce social inequalities in cancer screening, and a key feature in intervention research is to consult the target group. OBJECTIVE To explore ethnic minority women's own ideas and preferences for a cancer screening intervention and identify their attitudes to different strategies. METHODS An interview study with five focus group interviews, two group interviews with an interpreter and three individual interviews. Thirty-seven women from 10 non-Western countries contributed to the study. The interviews were audio-recorded and transcribed verbatim followed by a thematic analysis. RESULTS According to the women, a tailored intervention should focus on knowledge in the form of face-to-face teaching. The women further suggested information material in their own language with a simple, positive and concrete communication strategy. They would like to be involved in an awareness strategy and share the knowledge with their network. CONCLUSION Ethnic minority women were interested in a tailored intervention, and they were keen to contribute with ideas and preferences. The findings emphasized the potential of a tailored intervention with specific suggestions to the content when attempting to reduce inequality in cancer screening participation. PATIENT OR PUBLIC CONTRIBUTION Minority women were involved in the interview study.

Chatzistamatiou K, Tsertanidou A, Moysiadis T, Mouchtaropoulou E, Pasentsis K, Skenderi A, Stamatopoulos K, Agorastos T. Comparison of different strategies for the triage to colposcopy of women tested high-risk HPV positive on self-collected cervicovaginal samples. Gynecol Oncol 2021; 162:560-568. [PMID: 34210517 DOI: 10.1016/j.ygyno.2021.06.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 06/18/2021] [Accepted: 06/21/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To identify the optimal strategy for the triage of women who test high-risk (hr) HPV positive on self-collected cervicovaginal samples. METHODS This is a diagnostic accuracy sub-analysis of the GRECOSELF study, which reported on HPV-DNA testing with self-sampling in Greece. More than 13,000 women, 25-60 years old, who resided in rural areas of Greece, provided a self-collected cervicovaginal sample. Samples were tested for HPV-DNA and HPV16/18 genotyping with the cobas® HPV test (Roche® Molecular Systems, Pleasanton, CA, USA). HrHPV positive women were referred for colposcopy. Prior to colposcopy a physician-collected sample was obtained for cytology. After colposcopy/biopsy, women were classified as having cervical disease or not, and treated accordingly. RESULTS Out of 1070 hrHPV positive women, 773 were subjected to colposcopy. Seventeen triage strategies, combining HPV16/18 genotyping and cytology, were investigated. The strategy referring to colposcopy women positive for HPV16 regardless of the cytology report, and women positive for other hrHPVs, in case of a subsequent atypical squamous cells of undetermined significance or worse (ASCUS+) cytology report, presented optimal trade-off; sensitivity 96.36% [(95%CI: (91.41-100.0)], positive predictive value (PPV) 27.46% [95%CI: (21.16-33.76)], and number of colposcopies required to detect one case of Cervical Intraepithelial Neoplasia grade-2 or worse (CIN2+) 3.64. CONCLUSIONS The optimal strategy for the triage to colposcopy of hrHPV positive women, detected with the cobas® HPV test on self-collected cervicovaginal samples, is referring all HPV16 positive women directly to colposcopy, and women positive for HPV18 or other hrHPVs only after an ASCUS or worse cytology report.

Abstract
OBJECTIVES To increase effectiveness of the cervical cancer screening program, self-sampling can be an option. Both self-collected vaginal samples (SCV) and urine samples may be useful alternatives to clinician-taken cervical samples (CS). DESIGN Cross-sectional study. SETTING Colposcopy clinic. PARTICIPANTS Women (n=305) referred to colposcopy after abnormal cervical screening result or conditions like postcoital bleeding. INTERVENTION All women self-collected a urine and a vaginal sample prior to colposcopy, where a CS and biopsies were taken. All samples were tested for high-risk human papillomavirus (HPV) using the Cobas HPV assay. The gold standard was histology diagnoses (CIN2+/CIN3+) from biopsies obtained at the same examination. PRIMARY OUTCOME Absolute and relative sensitivity and specificity of HPV testing on SCV and urine to detect CIN2+/CIN3+ compared with the CS. SECONDARY OUTCOME The acceptability by women of self-sampling. RESULTS Both the vaginal and urine sample were comparable to the CS in identifying severe intraepithelial neoplasia (CIN2+/CIN3+). Absolute sensitivity ranged from 93% for urine samples to 96% for SCV for detecting CIN2+, which is comparable to the sensitivity of CS (overlapping 95% CI).The relative sensitivity for detecting CIN2+ was 1.00 (95% CI 0.96 to 1.04) for SCV and 0.96 (95% CI 0.91 to 1.03) for urine samples. At CIN3+, the relative sensitivity was 1.00 (95% CI 0.96 to 1.08) and 0.97 (95% CI 0.89 to 1.07) for SCV and urine samples, respectively. There were no statistical differences between the self-collected samples and the CS (McNemar's test >0.05). The relative specificity was also similar (1.03 (95% CI 0.95 to 1.12) for SCV and 0.98 (95% CI 0.89 to 1.09) for urine samples) (McNemar's test >0.05).The acceptability of self-sampling was evaluated by questionnaire. The women found the instructions on sample collection easy to understand and were positive about self-sampling with a preference for the urine sample. CONCLUSION Self-sampling by SCV and urine is a clinically safe alternative to CS with a high degree of acceptability.

Abstract
PURPOSE OF REVIEW This review updates progress in the human papillomavirus (HPV)-based revolution in cervical screening and vaccination predicted to eventually eliminate cervical cancer. RECENT FINDINGS HPV PCR, patented by the author in 1987, has recently begun to replace cytology for primary cervical screening. I highlight the findings from large randomized clinical trials that have brought about this change, and progress with implementation. Australia was the first to introduce a national, publicly-funded HPV PCR-based program of primary screening, on 1 December 2017. The United Kingdom is set to follow, as are other countries. The widespread preference of self-sampling by under-screened women in particular will increase the effectiveness of population screening when using HPV tests. Coupled with improved vaccination now that more effective (nonavalent) HPV vaccines are being introduced, recent modeling predicts that cervical cancer will be markedly reduced, or even eliminated, in coming decades. SUMMARY The recent or pending change to more accurate cervical screening by HPV detection using PCR in various countries means less frequent screening for women. Women with an aversion to having their sample collected by a physician can collect their sample themselves, either at the doctor's rooms or at home, the sample then being mailed to the testing laboratory.

Public Health Nurs 2020; 37:677-695. [PMID: 32744371 DOI: 10.1111/phn.12782] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Revised: 07/10/2020] [Accepted: 07/11/2020] [Indexed: 01/09/2023]
Abstract
OBJECTIVE To examine methods and results of studies assessing self-collection of cervico-vaginal samples for human papillomavirus (HPV) testing by immigrant women for insights into how future research using this method with unique subpopulations of women may improve the rates of cervical cancer screening (CCS) compared to current strategies. DATA SOURCES Four electronic databases were systematically searched through March 2020, with no limits applied. A manual review of reference lists was also completed. STUDY SELECTION The search resulted in 63 articles. After removal of duplicates, 36 were reviewed against inclusion criteria. A manual review of reference lists yielded two additional studies. The final sample included 15 relevant publications representing 13 unique empirical studies. DATA EXTRACTION Data related to study methodology and empirical results were extracted into table form. DATA SYNTHESIS The methods of the studies were summarized and synthesized, including diversity of participants, community engagement, including collaboration with public health nurses or community health workers. In addition, methods and findings related to the educational components of the studies, and empirical findings related to various cultural groups, were described. CONCLUSION To reduce health disparities in CCS, researchers should focus on diverse groups, such as immigrant women, to understand important individual and group-specific factors that may influence screening, including whether self-collection of samples for HPV testing along with appropriate education and support for follow-up will address these factors.

Abstract
HPV self-sampling (HPV-SS) can increase cervical cancer screening participation by addressing barriers in high- and low- and middle-income settings. Successful implementation of HPV-SS programs will depend on understanding potential costs and health effects. Our objectives were to summarize the methods and results of published HPV-SS cost and cost-effectiveness studies, present implications of these results for HPV-SS program implementation, and identify knowledge gaps. We followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. One reviewer searched online databases for articles published through June 12, 2019, identified eligible studies, and extracted data; a second reviewer checked extracted data for accuracy. Eligible studies used an economic model to compare HPV-SS outreach strategies to standard-of-care tests. Of 16 eligible studies, 14 reported HPV-SS could be a cost-effective strategy. Studies differed in model type, HPV-SS delivery methods, triage strategies for positive results, and target populations. Most (9/16) modeled HPV-SS in European screening programs, 6/16 targeted women who were underscreened for cervical cancer, and 5/16 modeled HPV-SS in low- and middle-income countries. The most commonly identified driver of HPV-SS cost-effectiveness was the level of increase in cervical cancer screening attendance. Lower HPV-SS material and testing costs, higher sensitivity to detect cervical precancer, and longer duration of underscreening among HPV-SS users were also associated with increased cost-effectiveness. Future HPV-SS models in high-income settings should explore the effect of widespread vaccination and new triage strategies such as partial HPV genotyping. Knowledge gaps remain about the cost-effectiveness of HPV-SS in low- and middle-income settings.

Abstract
OBJECTIVES To evaluate experiences and reactions after receiving a mailed, unsolicited human papillomavirus self-sampling kit and identify psychosocial correlates of using kits. METHODS Survey participants were underscreened women aged 30-64 who were mailed human papillomavirus kits as part of a pragmatic trial at Kaiser Permanente Washington, a United States integrated health care system. Six months after the mailing, we invited kit returners and non-returners to complete a web survey that measured psychosocial factors (e.g. cervical cancer/human papillomavirus knowledge, attitudes toward screening), experiences, and reactions to kits. We compared responses between kit returners and non-returners. RESULTS Comparing 116 kit returners (272 invited) and 119 non-returners (1083 invited), we found no clinically significant differences in psychosocial factors. Overall, survey respondents showed knowledge gaps in human papillomavirus natural history (82% did not know human papillomavirus infection can clear on its own) and interpreting human papillomavirus test results (37% did not know a human papillomavirus-negative result indicates low cancer risk). Kit returners found kits convenient and easy to use (>90%). The most common reason for non-return was low confidence in ability to correctly use a kit, although many non-returners (49%) indicated that they would consider future use. Women reported low trust in human papillomavirus testing to identify women at high risk for cervical cancer (52% in returners, 42% in non-returners). CONCLUSIONS Screening programs could improve uptake and acceptability of human papillomavirus self-sampling through outreach materials that emphasize the high efficacy of human papillomavirus testing for cervical cancer screening and educate patients about how to interpret results.

Abstract
In this nationwide register-based cohort study, we examined cervical cancer screening participation among immigrants in Denmark by country and region of origin. Furthermore, we assessed whether differences in screening participation between immigrants and Danish-born women were explained by sociodemographic or health-related characteristics, and examined predictors of participation among immigrants. Using high-quality registries, we identified women invited for cervical cancer screening during 2008-2009 and retrieved individual-level data on sociodemographic-, health- and immigration-related characteristics. A total of 610,907 women were followed for up to 2.9 years after screening invitation. We estimated the probability of participation using the Aalen-Johansen estimator and the hazard ratios (HRs) of participation using Cox regression. The probability of participation within follow-up was 74.5% (95% CI, 74.4%-74.6%) in Danish-born women; 61.2% (95% CI, 60.4%-62.1%) in Western immigrants; and 61.3% (95% CI, 60.9%-61.8%) in non-Western immigrants. Participation in immigrants varied by region of origin from 44.3% (95% CI, 41.4%-47.4%) in immigrants from North America, New Zealand and Australia to 67.8% (95% CI, 65.4%-70.3%) in immigrants from South- and Central America. Substantial variation was seen between specific countries of origin. Differences in participation between immigrants and Danish-born women were not explained by sociodemographic or health-related characteristics. Predictors of low participation in immigrants included lower income, unemployment, being unmarried, having a history of schizophrenia or other psychoses, and ≤5 years' stay in Denmark. In conclusion, cervical cancer screening participation in immigrants varied by region and country of origin, but all immigrant groups had lower participation than Danish-born women.

Abstract
Introduction Human papillomavirus (HPV) self-sampling test kits may increase screening for and early detection of cervical cancer and reduce its burden globally. To inform WHO self-care guidelines, we conducted a systematic review and meta-analysis of HPV self-sampling among adult women on cervical (pre-)cancer screening uptake, screening frequency, social harms/adverse events and linkage to clinical assessment/treatment. Methods The included studies compared women using cervical cancer screening services with HPV self-sampling with women using standard of care, measured at least one outcome, and were published in a peer-reviewed journal. We searched PubMed, the Cumulative Index to Nursing and Allied Health Literature (CNIAHL), Latin American and Caribbean Health Sciences Literature (LILACS) and Embase through October 2018. Risk of bias was assessed using the Cochrane tool for randomised controlled trials (RCTs) and the Evidence Project tool for non-randomised studies. Meta-analysis was conducted using random-effects models to generate pooled estimates of relative risk (RR). Results 33 studies in 34 articles with 369 017 total participants met the inclusion criteria: 29 RCTs and 4 observational studies. All studies examined HPV self-sampling; comparison groups were standard of care (eg, Pap smear, visual inspection with acetic acid, clinician-collected HPV testing). 93% of participants were from high-income countries. All 33 studies measured cervical cancer screening uptake. Meta-analysis found greater screening uptake among HPV self-sampling participants compared with control (RR: 2.13, 95% CI 1.89 to 2.40). Effect size varied by HPV test kit dissemination method, whether mailed directly to home (RR: 2.27, 95% CI 1.89 to 2.71), offered door-to-door (RR: 2.37, 95% CI 1.12 to 5.03) or requested on demand (RR: 1.28, 95% CI 0.90 to 1.82). Meta-analysis showed no statistically significant difference in linkage to clinical assessment/treatment between arms (RR: 1.12, 95% CI 0.80 to 1.57). No studies measured screening frequency or social harms/adverse events. Conclusion A growing evidence base, mainly from high-income countries and with significant heterogeneity, suggests HPV self-sampling can increase cervical cancer screening uptake compared with standard of care, with a marginal effect on linkage to clinical assessment/treatment. Systematic review registration number PROSPERO CRD42018114871.

Abstract
Chlamydia trachomatis infection is the most common sexually transmitted bacterial infection among women. In Brazil, there is no organized screening program for C. trachomatis, and the actual prevalence of infection is unknown. This study aimed to determine the prevalence of C. trachomatis infection in women living in riverside communities in the Amazon, using self-collection employing the Evalyn® Brush and polymerase chain reaction. A total of 299 riverine women aged 18-81 years, mean age 35.7 (±12.8) years, predominantly agricultural workers, with low schooling and living with a partner, participated in this study. The prevalence of C. trachomatis infection was found to be 3.7% (95% CI 1.8-6.5), most of them being symptomatic. The mean age of the first sexual intercourse reported by women was 15.2 (±2.3) years, and the majority reported having had none or only one partner in the last 12 months, with very low adherence to consistent condom use (15.4%). Most women (98.3%) reported having approved using the vaginal self-collecting brush, and only 4.7% reported having difficulty in handling the brush. We consider that a vaginal self-collecting device is adequate for diagnosing C. trachomatis infection in women living in remote, hard-to-reach areas.
