Hansen BT, Nygård M, Castle PE, Burger EA, Aasbø G. Sociodemographic characteristics associated with cervical cancer screening participation by send-to-all and opt-in HPV self-sampling: Who benefits? Results from a randomized controlled trial among long-term non-attending women in Norway. Int J Cancer 2024; 155:1053-1067. [PMID: 38751040 DOI: 10.1002/ijc.34989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 03/11/2024] [Accepted: 04/12/2024] [Indexed: 07/16/2024]
Abstract
With the objective to investigate associations between sociodemographic characteristics and participation in interventions designed to increase participation in cervical cancer screening among under-screened women, we randomized a random sample of 6000 women in Norway aged 35-69 years who had not attended cervical screening for ≥10 years to receive either (i) a reminder to attend regular screening (control), (ii) an offer to order a self-sampling kit (opt-in), or (iii) a self-sampling kit unsolicited (send-to-all). We analyzed how sociodemographic characteristics were associated with screening participation within and between screening arms. In the send-to-all arm, increased screening participation ranged from 17.1% (95% confidence interval [95% CI] = 10.3% to 23.8%) to 30.0% (95% CI = 21.5% to 38.6%) between sociodemographic groups. In the opt-in arm, we observed smaller, and at times, non-significant increases within the range 0.7% (95% CI = -5.8% to 7.3%) to 19.1% (95% CI = 11.6% to 26.7%). In send-to-all versus control comparisons, there was greater increase in participation for women in the workforce versus not (6.1%, 95% CI = 1.6% to 10.6%), with higher versus lower income (7.6%, 95% CI = 2.2% to 13.1%), and with university versus primary education (8.5%, 95% CI = 2.4% to 14.6%). In opt-in versus control comparisons, there was greater increase in participation for women in the workforce versus not (4.6%, 95% CI = 0.7% to 8.5%), with higher versus lower income (6.3%, 95% CI = 1.5% to 11.1%), but lower increase for Eastern European versus Norwegian background (-12.7%, 95% CI = -19.7% to -5.7%). Self-sampling increased cervical screening participation across all sociodemographic levels, but inequalities in participation should be considered when introducing self-sampling, especially with the goal to reach long-term non-attending women.

Randomized experimental population-based study to evaluate the acceptance and completion of and preferences for cervical cancer screening. PLoS One 2024; 19:e0306130.

Abstract
Cervical cancer has high incidence and mortality rates, especially in less-developed countries. Prevention methods are well established, but there are still barriers preventing some Brazilian women from undergoing a Pap sample. The objective of the study was to evaluate the acceptance, preferences and completion of four screening methods. This has an experimental design (community trial). A total of 164 participants who had never had a Pap sample or had not had one for more than three years were included. The city's urban area was stratified by census tracts and divided according to income and education levels. Women belonging to the lower-income strata were considered in the study. Random blocks were numbered into five intervention groups (Group 1- Pap sample at the hospital; Group 2- Pap sample in the mobile unit; Group 3- urine self-collection; Group 4- vaginal self-collection; Group 5- woman's choice). Only 164 women met all of the eligibility criteria (15.3%). Most of them accepted the assigned method (92%), but only 84% of the women completed the collection step. The acceptance rates were as follows: Group 1 (100%), Group 2 (64.5%), Group 3 (100%) and Group 4 (91.4%). In Group 5, the women's preferences were distributed as follows: examination performed at the hospital, 13 women (33.3%); examination performed at the mobile unit, 11 women (28.2%); urine self-collection, 11 women (28.2%); and vaginal self-collection, 4 women (10.3%). This study suggests that methods that allow cervical sampling collected near the women's domicile might improve the acceptance and completion of preventive tests. This finding is relevant for the development of new cervical cancer screening strategies.

Abstract
Objective To analyze the demographic and socioeconomic determinants of non-participation in cervical, colorectal and breast cancer screening programs in Denmark. Study design and setting We 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. Results Significant 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). Conclusions Demographic 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.

A systematic review of the cost-effectiveness of interventions to increase cervical cancer screening among underserved women in Europe. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2024; 25:829-844. [PMID: 37726429 PMCID: PMC11192698 DOI: 10.1007/s10198-023-01627-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 08/16/2023] [Indexed: 09/21/2023]
Abstract
BACKGROUND This study aimed to conduct a systematic review of the cost-effectiveness studies of interventions to increase cervical cancer screening uptake rates in underserved women in Europe. METHODS A search of Embase, Medline, Global Health, PsychINFO, and NHS Economic Evaluation Database was conducted for studies published between January 2000 and September 2022. Studies were eligible if they analysed the cost-effectiveness of any interventions to improve participation in cervical cancer screening among underserved women of any age eligible to participate in cervical cancer screening in European countries, in any language. Study characteristics and cost-effectiveness results were summarised. Study quality was assessed using the Drummond Checklist, and methodological choices were further compared. RESULTS The searches yielded 962 unique studies, with 17 of these (from twelve European countries) meeting the eligibility criteria for data extraction. All studies focused on underscreened women as an overarching group, with no identified studies focusing on specific subgroups of underserved women. Generally, self-HPV testing and reminder interventions were shown to be cost-effective to increase the uptake rates. There was also research showing that addressing access issues and adopting different screening modalities could be economically attractive in some settings, but the current evidence is insufficient due to the limited number of studies. CONCLUSION This systematic review has revealed a gap in the literature on the cost-effectiveness of interventions to improve uptake rates of cervical cancer screening through tailored provision for specific groups of underserved women.

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.

The role of mesolevel characteristics of the health care system and socioeconomic factors on health care use - results of a scoping review. Int J Equity Health 2024; 23:37. [PMID: 38395914 PMCID: PMC10885500 DOI: 10.1186/s12939-024-02122-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 02/04/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Besides macrolevel characteristics of a health care system, mesolevel access characteristics can exert influence on socioeconomic inequalities in healthcare use. These reflect access to healthcare, which is shaped on a smaller scale than the national level, by the institutions and establishments of a health system that individuals interact with on a regular basis. This scoping review maps the existing evidence about the influence of mesolevel access characteristics and socioeconomic position on healthcare use. Furthermore, it summarizes the evidence on the interaction between mesolevel access characteristics and socioeconomic inequalities in healthcare use. METHODS We used the databases MEDLINE (PubMed), Web of Science, Scopus, and PsycINFO and followed the 'Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols extension for scoping reviews (PRISMA-ScR)' recommendations. The included quantitative studies used a measure of socioeconomic position, a mesolevel access characteristic, and a measure of individual healthcare utilisation. Studies published between 2000 and 2020 in high income countries were considered. RESULTS Of the 9501 potentially eligible manuscripts, 158 studies were included after a two-stage screening process. The included studies contained a wide spectrum of outcomes and were thus summarised to the overarching categories: use of preventive services, use of curative services, and potentially avoidable service use. Exemplary outcomes were screening uptake, physician visits and avoidable hospitalisations. Access variables included healthcare system characteristics such as physician density or distance to physician. The effects of socioeconomic position on healthcare use as well as of mesolevel access characteristics were investigated by most studies. The results show that socioeconomic and access factors play a crucial role in healthcare use. However, the interaction between socioeconomic position and mesolevel access characteristics is addressed in only few studies. CONCLUSIONS Socioeconomic position and mesolevel access characteristics are important when examining variation in healthcare use. Additionally, studies provide initial evidence that moderation effects exist between the two factors, although research on this topic is sparse. Further research is needed to investigate whether adapting access characteristics at the mesolevel can reduce socioeconomic inequity in health care use.

Abstract
OBJECTIVE Routine, population-wide cervical screening programmes reduce cervical cancer incidence and mortality. However, socioeconomically deprived communities and ethnic minority groups typically have lower uptake in comparison to the general population and thus are described as 'underserved.' A systematic qualitative literature review was conducted to identify relevant determinants of participation for these groups. METHODS Online databases were searched for relevant literature from countries with well-established, call-recall screening programmes. Overall, 24 articles were eligible for inclusion. Data was synthesized via Framework synthesis. Dahlgren & Whitehead's social model of health was used as a broad a priori coding framework. RESULTS Participation was influenced by determinants at multiple levels. Overall, patient-provider relationships and peer support facilitated engagement. Cultural disparities, past healthcare experience and practical barriers hindered service access and exacerbated negative thoughts, feelings and attitudes towards participation. Complex interrelationships between determinants suggest barriers have a cumulative effect on screening participation. CONCLUSIONS These findings present a framework of psychosocial determinants of cervical screening uptake in underserved women and emphasise the role of policy makers and practitioners in reducing structural barriers to screening services. Additional work, exploring the experience of those living within socioeconomically disadvantaged areas, is needed to strengthen understanding in this area.

Abstract
INTRODUCTION Cervical cancer is a significant public health problem for women worldwide. It is the fourth most frequent cancer in women globally. While early detection of cancerous lesions through screening tests leads to a better prognosis and a better chance of being cured, the number of people who go for screening is still low, especially for groups that are marginalized, like immigrant women. OBJECTIVE The purpose of this study was to identify cervical cancer screening practices and factors influencing screening status among Yemeni immigrant women living in the Klang Valley, Malaysia. METHOD A cross-sectional study among 355 randomly selected respondents between the ages of 20 and 65 was conducted through an online survey. A questionnaire was sent directly to the participants via WhatsApp. The analysis was conducted using SPSS 25 with a significance level of 0.05. It included descriptive analysis, chi-square and multiple logistic regression. RESULTS The response rate was 59%, with the majority of the respondents being married and between the ages of 35 and 49. Screening was reported at 23.1% in the previous three years. The final model revealed that age group 50-65 years (AOR = 5.39, 95% CI: 1.53-18.93), insurance status (AOR 2.22, 95% CI = 1.15-4.3), knowledge (AOR = 6.67, 95% CI = 3.45-12.9), access to health care facilities (AOR = 4.64, 95% CI = 1.29-16.65), and perceived barriers (AOR = 2.5, 95% CI = 1.3-4.83) were significant predictors of cervical screening uptake among Yemeni immigrant women in Malaysia (p<0.05). CONCLUSION According to the results, cervical cancer screening was found to be low among Yemeni immigrant women. The predictors were age group 50-65 years, insurance status, knowledge, access to health care facilities and perceived barriers. Efforts to enhance immigrant women's participation in cervical cancer screening must tackle barriers to access to healthcare services as well as expand cervical cancer screening education programs.

CANCER RESEARCH COMMUNICATIONS 2023; 3:1823-1829. [PMID: 37700796 PMCID: PMC10494786 DOI: 10.1158/2767-9764.crc-23-0191] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 06/26/2023] [Accepted: 08/14/2023] [Indexed: 09/14/2023]
Abstract
As life expectancy increases, the effectiveness of cervical cancer screening programs needs to be reassessed for the older population. We addressed the effect of test history in and outside organized screening at age 50-64 years on later cervical cancer risk. A case-control study was conducted by deriving 229 cases of 65-79 years old women with invasive cervical cancer in 2010-2019 from the Finnish Cancer Registry. Ten controls were matched for each case by birth year and hospital district. The effect of test uptake and abnormal results in 50-64 year olds on cancer risk was investigated using conditional logistic regression and adjusted for self-selection. Test uptake within the 50-64 years age group showed 75% lower odds of cervical cancer [adjusted OR (aOR) = 0.25; 95% confidence interval (95% CI), 0.18-0.35]. Untested women had 4.9 times higher odds than those tested with normal results (aOR = 4.86; 95% CI, 3.42-6.92). Having at least one abnormal test result increased the odds by 2.5 when compared with only normal results but showed lower odds when compared with untested women. The importance of testing is exhibited by the result showing a reduction of odds of cancer to one-fourth for those tested compared with untested. Similarly, receiving abnormal results was protective of cancer compared with having no tests highlighting the importance of proper follow-up. Therefore, screening history should be considered when further developing cervical cancer screening programs with special interest in non-attenders and those receiving abnormal results at older ages. Significance To our knowledge, this is the first study from Finnish data describing the effect of test history on later cervical cancer at older ages. Focusing on the cervical tests taken within the Finnish national screening program and outside it highlights the overall importance of having cervical tests and adds this study into the slowly increasing number of studies considering all cervical testing in Finland.

Vaccination against Human Papillomavirus (HPV) and screening programs can significantly reduce CC mortality rates. Hence, executing cost-effective public health policies for prevention and surveillance is crucial. However, defining policies that make the best use of the available resources is not easy, as it requires predicting the long-term costs and results of interventions on a changing population. Since the simpler task of predicting the results of public health policies is difficult, devising those that make the best usage of available resources is an arduous challenge for decision-makers. METHODS This paper proposes a fine-grained epidemiological simulation model based on differential equations, to effectively predict the costs and effectiveness of CC public health policies that include vaccination and screening. The model represents population dynamics, HPV transmission within the population, likelihood of infection clearance, virus-induced appearance of precancerous lesions and eventually CC, as well as immunity gained with vaccination and early detection with screening. RESULTS We offer a compartmentalized modeling approach that separates population, epidemics, and intervention concerns. We instantiate models with actual data from a Colombian case study and analyze their results to show how our modeling approach can support CEA studies. Moreover, we implement models in an open-source software tool to simultaneously define and evaluate multiple policies. With the support of the tool, we analyze 54 policies within a 30-year time horizon and use as a comparator the CC policy that has been used until recently. We identify 8 dominant policies, the best one with an ICER of 6.3 million COP (Colombian Pesos) per averted DALY. We also validate the modeling approach against the available population and HPV epidemic data. The effects of uncertainty in the values of key parameters (discount rate, sensitivity of screening tests) is evaluated through one-way sensitivity analysis. CONCLUSIONS Our modeling approach can provide valuable support for healthcare decision-makers. The implementation into an automated tool allows customizing the analysis with country-specific data, flexibly defining public health policies to be evaluated, and conducting disaggregate analyses of their cost and effectiveness.

Unpacking the Lay Epidemiology of Cervical Cancer: A Focus Group Study on the Perceptions of Cervical Cancer and Its Prevention among Women Late for Screening in Norway. Healthcare (Basel) 2023; 11:healthcare11101441. [PMID: 37239727 DOI: 10.3390/healthcare11101441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 04/26/2023] [Accepted: 05/10/2023] [Indexed: 05/28/2023] Open
Abstract
Nonattendance for cervical cancer screening is often understood in terms of a lack of 'appropriate' or 'correct' knowledge about the risks and prevention of the disease. Few studies have explored how lay persons-the users themselves-interpret and contextualise scientific knowledge about cervical cancer. In this study, we address the following research question: How is the epidemiology of cervical cancer and its prevention discussed among women who are late for cervical cancer screening in Norway? We completed nine focus group interviews (FGIs) with 41 women who had postponed cervical screening. The analyses were both inductive and explorative, aiming to unpack the complexity of lay understandings of cervical cancer. Interactive associations expressed in the FGIs reflected multiple understandings of aetiology and risk factors, screening, and interpretations of responsibility for acquiring cervical cancer. The term 'candidacy' was employed to provide an enhanced understanding of lay reasoning about the explanations and predictions of cervical cancer, as reflected in the FGIs. Both interpretations of biomedical concepts and cultural values were used to negotiate acceptable and nuanced interpretations of candidacy for cervical cancer. Uncertainties about risk factors for acquiring cervical cancer was an important aspect of such negotiations. The study's findings provide an in-depth understanding of the contexts in which screening may be rendered less relevant or significant for maintaining health. Lay epidemiology should not be considered inappropriate knowledge but rather as a productive component when understanding health behaviours, such as screening attendance.

Abstract
BACKGROUND The participation of older adults in population health interventions constitutes a key factor in their physical, mental and social health. The aim of this study was to determine variables considered as enablers and barriers to participation in health programmes. METHODS The conceptual framework of the study was developed and population health interventions were operationalised as health programmes. A total of 805 older adults participated in a questionnaire survey. The questionnaire included questions about socio-demographic, health and social connectedness-related factors as well as participation in population health interventions/programmes. Multiple logistic regression was used to examine the relationship between respondents' characteristics and participation in the intervention. RESULTS Participation in health programmes was declared by 316 respondents. The enablers of participation were general practitioner's affability (OR = 2.638 [1.453-4.791], p = 0.001), three or more social activities (OR = 3.415 [1.477-7.894], p = 0.004), taking part in support groups (OR = 4.743 [1.255-17.929], p = 0.022) and involvement in Universities of the Third Age (OR = 2.829 [1.093-7.327], p = 0.032). The barriers were primary education (OR = 0.385 [0.215-0.690], p = 0.001), infrequent general practitioner's appointments (OR = 0.500 [0.281-0.888], p = 0.018) and lack of social activity (OR = 0.455 [0.299-0.632], p < 0.001). CONCLUSION The enablers of participation appeared to solely include variables regarding health service utilisation, patient experience and social activity, i.e., interpersonal and community relationships, not intrapersonal factors.

[PMID: 36767568 PMCID: PMC9915157 DOI: 10.3390/ijerph20032200] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 01/23/2023] [Accepted: 01/24/2023] [Indexed: 06/18/2023]
Abstract
Organized cervical cancer screening programs to promote the early identification of precancerous lesions have proven to be effective in decreasing the burden associated with cervical cancer, but knowledge regarding screening adherence among migrant women compared to that of native women has not been summarized. A systematic search of the literature on PubMed, Scopus and Embase led to the identification of 772 papers that were published up to July 2022 and reported population-based data regarding adherence to cervical screening. The screening participation rates among migrant women, compared to native women, were pooled using a random-effects meta-analysis. A total of 18 papers were included in the review, with most of them being conducted in Europe (83.3%). Overall, migrants showed a significantly lower participation rate compared to native women (OR for screening adherence: 0.54, 95% CI = 0.42-0.70). This discrepancy was especially evident for migrant women from North Africa and Sub-Saharan Africa (OR = 0.47, 95% CI = 0.35-0.63, and OR = 0.35, 95% CI = 0.24-0.49, respectively). The results of this systematic review emphasize the importance of increasing cervical cancer screening adherence among migrant women. A significant heterogeneity in screening adherence was observed based on the country of origin. Interventions aimed at reducing the disparities in screening participation should specifically consider how to improve the recruitment of migrant women.

Abstract
BACKGROUND The wide availability of mobile phones has made it easy to disseminate health-related information and make it accessible. With gamification, mobile apps can nudge people to make informed health choices, including attending cervical cancer screening. OBJECTIVE This matched retrospective cohort study examined the association between exposure to the FightHPV mobile app gamified educational content and having a cervical exam in the following year. METHODS Women aged 20 to 69 years who signed an electronic consent form after downloading the FightHPV app in 2017 (intervention group) were matched 1:6 with women of the same age and with the same screening history (reference group) in 2015. To estimate the impact of exposure to the FightHPV app, we estimated cumulative incidence and hazard ratios (HRs) with 95% CIs. We used data from the Norwegian Cervical Cancer Screening Program database and Statistics Norway to determine screening participation and outcomes, respectively. RESULTS We matched 3860 women in the control group to 658 women in the intervention group; 6 months after enrollment, 29.6% (195/658) of the women in the intervention group and 15.21% (587/3860) of those in the reference group underwent a cervical exam (P<.01). Women exposed to the FightHPV app were 2 times more likely to attend screening (adjusted HR 2.3, 95% CI 2.0-2.7), during which they were 13 times more likely to be diagnosed with high-grade abnormality (adjusted HR 12.7, 95% CI 5.0-32.5) than the women in the reference group. CONCLUSIONS Exposure to the FightHPV app significantly increased cervical cancer screening attendance across the various analyses and improved detection of women with high risk for cervical cancer. For the first time, we demonstrated the effectiveness of gamification combined with mobile technology in cancer prevention by empowering women to make active health-related decisions. Gamification can significantly improve the understanding of complicated scientific concepts behind interventions and increase the acceptance of proposed cancer control measures.

Abstract
Cervical cancer screening (CCS) by Pap tests is mainly performed by gynecologists in France, but also by general practitioners (GPs) and midwives. The screening uptake is insufficient to reduce the incidence of cervical neoplasms. Our aim was to investigate the association between screening rates in patients listed with GPs and the distance between GPs' offices and gynecology facilities. The population of 345 GPs, and their 93,918 female patients eligible for screening over 3 years (2013-2015), were derived from the Health Insurance claim database. We estimated the socioeconomic level of the geographical area of GPs' offices using the European Deprivation Index (EDI). The proximity of gynecology facilities was calculated by computing their distance from GPs' offices (in order to adjust the proximity of gynecology facilities with EDI and performance of smears by the GP). The number of gynecologists within 5 km of a GP's office was associated with the CCS rate increasing by 0.31% for every unit increase in the density of gynecologists within 5 km (p < 0.0001). The close proximity of gynecology facilities was not significantly associated with screening uptake among female patients when the office of the GP where they were registered was settled in a deprived area.

Role of Occupation in Shaping Cancer Disparities. Cancers (Basel) 2022; 14:cancers14174259.

Abstract
Simple Summary The investigation of cancer disparities is of major importance. In this paper, we address this issue through the occupational point of view, trying to capture how work and its related factors impact on cancer inequalities. The data we provide may increase awareness relevant to cancer control, and stimulate further studies aimed at the identification of the occupational determinants of cancer disparities and the quantification of their role. Abstract Cancer occurrence is characterized globally by profound socioeconomic differences. Occupation is a fundamental component of socioeconomic status. In this review, we discuss the role of occupation as a determinant of cancer disparities. First, we address the issue of participation in cancer screening programs based on income, health insurance, occupational status and job title. Second, we review the role of occupation in contributing to disparities by acting as a mediator between cancer and (i) education and (ii) race/ethnicity. Lastly, we analyze data from a multicenter case−control study of lung cancer to calculate the mediating role of occupational exposure to diesel exhaust, silica and welding fumes in the association between education and lung cancer. By addressing the complex paths from occupation to cancer inequalities from multiple points of view, we provide evidence that occupational-related characteristics, such as income, health insurance, unemployment and hazardous exposures impinge on cancer control and outcomes. The increasing awareness of these aspects is fundamental and should lead to public health interventions to avoid inequalities rising from occupational factors.

Abstract
BACKGROUND Cervical cancer screening participation is suboptimal in most settings. We assessed whether human papillomavirus (HPV) self-sampling may increase screening participation among long-term non-attenders in Norway. METHODS A pragmatic randomised controlled trial with participation as the primary outcome was initiated in the national cervical screening programme in March 2019. A random sample of 6000 women aged 35-69 years who had not attended screening for at least 10 years were randomised 1:1:1 to receive either (i) a reminder to attend regular screening (control), (ii) an offer to order a self-sampling kit (opt-in) for HPV testing or (iii) a self-sampling kit unsolicited (send-to-all) for HPV testing. RESULTS Total participation was 4.8%, 17.0% and 27.7% among control, opt-in and send-to-all (P < 0.0001; participation difference (%) send-to-all vs. control: 22.9 (95%CI: 20.7, 25.2); opt-in vs. control: 12.3 (95%CI: 10.3, 14.2); send-to-all vs. opt-in: 10.7 (95% CI: 8.0, 13.3)). High-risk HPV was detected in 11.5% of self-samples and 9.2% of clinician-collected samples (P = 0.40). Most women (92.5%) who returned a positive self-sample attended the clinic for triage testing. Of the 933 women screened, 33 (3.5%) had CIN2 + (1.1%, 3.7%, 3.8% among control, opt-in, and send-to-all, respectively), and 11 (1.2%) had cervical cancer (0%, 1.2%, 1.3% among control, opt-in, send-to-all, respectively). CONCLUSION Opt-in and send-to-all self-sampling increased screening participation among long-term, higher-risk non-attenders. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov NCT03873376.

Abstract
Background High screening coverage can effectively reduce the mortality in breast and cervical cancer. Further research on extending the coverage of breast and cervical cancer screening in China is required. This study explored factors influencing women's "two-cancer" screening service utilization using an ecological approach. Methods Data were obtained from the National Health Services Survey (NHSS) conducted in 2018 in Jiangsu, China. A total of 3,500 women aged 18-64 years were included in the analysis. Chi-squared test, hierarchical multiple logistic regression analysis, and binary logistic regression analysis were performed. Results In total, 44.1% of the women had been screened for breast cancer (BC) and 40.9% for cervical cancer (CC). Breast cancer screening (BCS) and cervical cancer screening (CCS) differed significantly in the following common categories: age, gestational experiences, chronic disease status, body mass index (BMI), exercise, health checkup, marital status, number of children, employment, education, family doctors, and health records. In the results of hierarchical multiple logistic regression analysis, the explanatory power of the final model was 37.5% and the area under the receiver operating characteristic curve was 0.812. The results showed that being in the age group of 35-64 years, having gestational experiences, having chronic diseases, exercising, having a health checkup, being married, having children, and being employed were statistically significant positive predictors of "two-cancer" screening adherence. The household size was a barrier. For BCS, obesity was also a negative factor, and a higher overall self-related health status was a positive factor. Being married and living in households of three or more families were not predictors. For CCS, having health records was also positively significant, while having chronic disease did not influence adherence. Conclusion The findings provide an ecological explanation for women's BCS and CCS service utilization. Both proximal and distal factors should be considered to achieve a high coverage rate.

Organized Breast and Cervical Cancer Screening: Attendance and Determinants in Rural China. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19148237.

Abstract
To evaluate the attendance and determinants of organized cervical and breast cancer (two-cancer) screening, especially higher-level factors, we conducted a cross-sectional survey in central China from June 2018 to November 2019 among 1949 women (age ≥ 35 years). We examined organizer-level factors, provider-level factors, receiver-lever factors and attendance and participation willingness of screening. The results indicate that the attendance and participation willingness of organized two-cancer screening was 61.19% and 77.15%, respectively. After adjustment for potential confounders, women who received screening notification were more likely to have greater participation willingness and higher attendance than those who received no notification (adjusted odds ratio [aOR] = 1.59, 95% confidence interval [CI]: 1.27-1.99; aOR = 98.03, 95% CI: 51.44-186.82, respectively). Compared with being notified about screening by GPs, being notified by community women's leaders and other community leaders were more likely to lead to greater willingness to participate again (aOR = 2.86, 95% CI: 1.13-7.24; aOR = 3.27, 95% CI: 1.26-8.48, respectively) and recommending screening to others (aOR = 2.18, 95% CI: 1.02-4.65; aOR = 4.14, 95% CI: 1.84-9.30, respectively). The results suggest that notification of women about screening by community leaders is an important organizer-level factor. As a part of public health services, the design and implementation of optimal cancer screening strategies may require public-sector involvement at the organizer level instead of a one-man show by the health sector.

Factors Promoting Breast, Cervical and Colorectal Cancer Screenings participation: A Systematic Review. Psychooncology 2022; 31:1435-1447. [PMID: 35793430 PMCID: PMC9541457 DOI: 10.1002/pon.5997] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 06/29/2022] [Accepted: 07/04/2022] [Indexed: 12/05/2022]
Abstract
Objective The present study aims at systematically reviewing research conducted on factors promoting breast, cervical and colorectal cancer screenings participation. Methods A literature search in MEDLINE/PubMed and PsycInfo from January 2017 to October 2021 was performed. Data extraction, researchers' full agreement and the inclusion criteria produced 102 eligible studies. Data were narratively synthesized and critically interpreted. Results Multiple factors favoring or hindering breast, cervical and colorectal cancer screenings were identified and summarized as factors operating at the individual level (background information, individual characteristics, emotions related to screening procedure and to cancer, knowledge and awareness), at the relational level (relationships with healthcare staff, significant others, community members), and at the healthcare system level (systems barriers/policy, lack of staff). A critical appraisal of studies revealed a fragmentation in the literature, with a compartmentalization of studies by type of cancer screening, country and specific populations of destination. Conclusions Overall findings indicated that greater integration of research results obtained independently for each cancer diagnosis and within the different countries/populations could foster a more comprehensive understanding of factors potentially enhancing the participation in breast, cervical and colorectal cancer screenings worldwide. This review, which is grounded in the current context of globalization and superdiversification in population, can help to enhance a better integration between research and practices, by supporting the development of more effective and inclusive evidence‐based interventions and health‐promotion campaigns worldwide. Research and practical implications are highlighted and discussed.

Cervical Cancer in the Baltic States: Can Intelligent and Personalised Cancer Screening Change the Situation? Acta Med Litu 2022; 29:19-26. [PMID: 36061942 PMCID: PMC9428648 DOI: 10.15388/amed.2022.29.1.18] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 05/24/2022] [Accepted: 06/06/2022] [Indexed: 11/24/2022] Open
Abstract
The three Baltic States (Estonia, Latvia, and Lithuania) are among the European Union countries with the highest incidence and mortality rates for cervical cancer. In order to tackle this public health challenge, there is an urgent need to implement more advanced and effective methods in cervical cancer prevention in Baltic countries. Nationwide cervical cancer screening programs in the Baltic States commenced in 2004–2009. While the organized screening programs in these countries differ in some relevant details (target age groups, screening interval), the underlying principles and problems, barriers are universal. However, the outcomes of present screening programs are unsatisfactory. In addition, universal screening programs are extremely costly. There is a potential need for more intelligent and personalized cervical cancer screening program. In 2019 the project “Towards elimination of cervical cancer: intelligent and personalized solutions for cancer screening” (2020–2023) was developed with the main objective – to develop improved and personalized cancer screening methods within a sustainable health care system. It is expected, that more sophisticated cervical cancer screening model will be implemented in Estonia, Latvia, and Lithuania, and will have a positive impact to epidemiology of cervical cancer and public health in general.

Women with obesity participate less in cervical cancer screening and are more likely to have unsatisfactory smears: Results from a nationwide Danish cohort study. Prev Med 2022; 159:107072. [PMID: 35460722 DOI: 10.1016/j.ypmed.2022.107072] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 03/22/2022] [Accepted: 04/18/2022] [Indexed: 11/21/2022]
Abstract
Some studies found an association between obesity and increased cervical cancer risk, but potential mechanisms are unknown. In this nationwide register-based cohort study, we investigated the association between overweight/obesity and cervical cancer screening participation and risk of unsatisfactory smears. The study population was identified in the Danish Medical Birth Registry. We included 342,526 women aged 23-49 years with pre-pregnancy body mass index (BMI) registered during 2004-2013. Screening participation and unsatisfactory smears during up to four years after child birth were identified in a nationwide pathology register. We used absolute risk regression to estimate the relative absolute risk (RAR) with 95% confidence intervals (CIs) of screening participation according to BMI, adjusted for age, calendar year, sociodemographic characteristics, parity and previous high-grade cervical intraepithelial neoplasia. Among those who were screened (n = 295,482), we used log-binomial regression to investigate the relative risk (RR) of an unsatisfactory smear according to BMI, adjusted for age, year, parity, oral contraceptive use and pathology department. A lower proportion of obese women (79.3%) than women of normal weight (85.8%) were screened, and obese women had lower adjusted probability of being screened than women of normal weight (RARadjusted = 0.94, 95% CI, 0.93-0.95). A higher proportion of obese women (2.4%) than women of normal weight (1.7%) had an unsatisfactory smear, and this association remained after adjustments (RRadjusted = 1.28, 95% CI, 1.19-1.38). In conclusion, women with obesity were less likely to participate in cervical cancer screening and more likely to have an unsatisfactory smear than women of normal weight.

Virus against virus: strategies for using adenovirus vectors in the treatment of HPV-induced cervical cancer. Acta Pharmacol Sin 2021; 42:1981-1990.

Abstract
Although most human papillomavirus (HPV) infections are harmless, persistent infection with high-risk types of HPV is known to be the leading cause of cervical cancer. Following the infection of the epithelium and integration into the host genome, the oncogenic proteins E6 and E7 disrupt cell cycle control by inducing p53 and retinoblastoma (Rb) degradation. Despite the FDA approval of prophylactic vaccines, there are still issues with cervical cancer treatment; thus, many therapeutic approaches have been developed to date. Due to strong immunogenicity, a high capacity for packaging foreign DNA, safety, and the ability to infect a myriad of cells, adenoviruses have drawn attention of researchers. Adenovirus vectors have been used for different purposes, including as oncolytic agents to kill cancer cells, carrier for RNA interference to block oncoproteins expression, vaccines for eliciting immune responses, especially in cytotoxic T lymphocytes (CTLs), and gene therapy vehicles for restoring p53 and Rb function.

Abstract
Cervical cancer screening delivery remains suboptimal. Understanding the multiple influences on use of screening is important to designing interventions. We describe the influence of patient, primary care provider (PCP), and clinic characteristics on whether a woman is up-to-date with cervical screening as of December 2016. PCPs (n = 194) and their female screen-eligible patients age 21-65 years (n = 32,115) were included in this cross-sectional analysis of patients from two primary care networks linked to a contemporaneous PCP survey. Principal independent variables for patients included: age, race, insurance, continuity of care; for PCP included: overall satisfaction with the practice of medicine, gender, hours worked per week, financial support for achieving clinical targets; and for clinic included: routine receipt of data on preventive care performance and language translation resources. Overall, 66.6% of women were up-to-date. Women were less likely to be up-to-date with cervical cancer screening if they were younger and were more likely to be screened if they were Black, Hispanic or Asian vs. White. Women with greater continuity of primary care or with a female PCP were more likely to be up-to-date (1.52; 1.33-1.75); those who received care in a clinic that was less prepared to manage language translation were less likely to be up-to-date (0.78; 0.65-0.95). Patient, provider, and clinic factors all influence use of cervical cancer screening. Systems interventions like improving continuity of care, promoting translation services, or enhanced efforts to track screening among patients of male PCPs may improve delivery.

Ann Fam Med 2021; 19:396-404. [PMID: 34546946 PMCID: PMC8437575 DOI: 10.1370/afm.2715] [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: 02/23/2020] [Revised: 11/23/2020] [Accepted: 02/08/2021] [Indexed: 11/09/2022] Open
Abstract
PURPOSE Primary care physicians have an important role in encouraging adequate cancer screening. Disparities in cancer screening by socioeconomic status (SES) may affect presentation stage and cancer survival. This study aimed to examine whether breast, colorectal, and cervical cancer screening rates in women differed by SES and age, and whether screening rates and SES disparities changed after introduction of a primary care-based national quality indicator program. METHODS This repeated cross-sectional study spanning 2002-2017 included all female Israeli residents in age ranges appropriate for each cancer screening assessed. SES was measured both as an individual-level variable based on exemption from copayments and as an area-level variable using census data. RESULTS In 2017, the most recent year in the study period, screening rates among 1,529,233 women were highest for breast cancer (70.5%), followed by colorectal cancer (64.3%) and cervical cancer (49.6%). Women in the highest area-level SES were more likely to undergo cervical cancer screening compared with those in the lowest (odds ratio = 3.56; 99.9% CI, 3.47-3.65). Temporal trends showed that after introduction of quality indicators for breast and colorectal cancer screening in 2004 and 2005, respectively, rates of screening for these cancers increased, with greater reductions in disparities for the former. The quality indicator for cervical cancer screening was introduced in 2015, and no substantial changes have occurred yet for this screening. CONCLUSIONS We found increased uptake and reduced socioeconomic disparities after introduction of cancer screening indicators. Recent introduction of a cervical cancer screening indicator may increase participation and reduce disparities, as has occurred for breast and colorectal cancer screening. These findings related to Israel's quality indicators program highlight the importance of primary care clinicians in increasing cancer screening rates to improve outcomes and reduce disparities.

Abstract
OBJECTIVE To identify reasons among Brazilian women for never having a Pap test. DESIGN We designed a cross-sectional study that used data from the National Health Survey. SAMPLE Two thousand four hundred and two women 25-64 years old who never had a pap test. MEASURES Variables were age, race, education, marital status, housing condition, primary health care access, health insurance, self-perceived health, and social support network. We calculated the prevalence of different reasons and odds ratios for each. RESULTS The most frequent reason for never having a test were linked to women thinking the test was unnecessary (42.3%) which had a significant association with marital status (OR = 1.52; 95% CI = 1.07-1.91), age (OR = 1.56; 95% CI = 1.21-1.99), area of residence (OR = 1.15; 95% CI = 1.02-1.39), having a health insurance (OR = 1.18; 95% CI = 1.01-1.36), and self-perceived health (OR = 1.42; 95% CI = 1.28-1.56). The second most frequent reason was not knowing they needed a test (22.9%) which was associated with age (OR = 1.95; 95% CI = 1.74-2.16) and self-perceived health (OR = 1.56; 95% CI = 1.33-1.80). CONCLUSIONS The findings suggest lack of knowledge about cervical cancer and its prevention among Brazilian women. We consider it essential that the health service can provide the test, as well as the necessary guidelines for raising the awareness of the target audience.

Abstract
OBJECTIVE It has been proposed that cervical cancer screening should be continued in women with previous abnormal results or irregular attendance. We examined the coverage and factors that might influence cervical testing beyond the age range of the organized cervical screening programme in Finland. The national programme invites women in every five years least until the age of 60. After the stopping age, only opportunistic service is available. METHODS Data on cervical testing were collected from the Mass Screening Registry and providers of opportunistic Pap/HPV-testing and were linked with information on socio-economic variables. The study included 373,353 women who had at least one invitation to the national screening programme between ages 50-60 years, and who were aged 65-74 years in the follow-up period 2006-2016. Multivariable binomial regression models were conducted to determine associations. RESULTS Altogether 33% of the study population had been tested at least once at ages 65-74 years. Previous regular screening attendance (adjRR 1.70; 95% CI 1.67-1.73) and earlier abnormal results (adjRR 2.08; 95% CI 2.04-2.12) were most clearly related to higher testing adherence at older age. Other factors related to higher testing adherence were urban area of residence, domestic mother tongue, high education level, and high socio-economic status. CONCLUSION Testing at older age was frequent with normal results, whereas only a small proportion of women with earlier abnormal results or irregular attendance were tested. The upper age limit of the national programme should be raised to 65 years, and the invitations thereafter should be targeted to selected high-risk groups.

Investigating the decrease in participation in the Dutch cervical cancer screening programme: The role of personal and organisational characteristics. Prev Med Rep 2021; 22:101328.

Abstract
Declining attendance in the Dutch cervical cancer screening programme was recently observed, coinciding with preparations for implementing primary hrHPV-based screening, which was implemented in January 2017. We aimed to investigate which factors were related to decreased attendance. We conducted a population-based cohort study including all women aged 30 to 60 years who were eligible for screening between 2014 and 2018. Attendance was defined as participation in the screening programme within 15 months of the start of the invitation-eligible year. We used data from the Dutch pathology archive (PALGA) linked with data from Statistics Netherlands to investigate population characteristics (position in the household, household income, socio-economic status, number of people in the household, migration background, age) and data from the five Dutch screening organisations (SO) to investigate the effect of cessing self-inviting GP's ('inviting organisation'). SO's were termed SO 1 to 5. Higher attendance rates were observed in women who were employed (60.8%), married (62.9%), Dutch (61.2%), in the highest income bracket (63.4%), living in households with four persons (65.3%) and women who were invited by their GP (69.8%). Differences in personal characteristics did not explain the decline in attendance rates. By adjusting for whether the GP or the SO sent the invitation, the differences in attendance rates between 2014 and 2015 and 2016 and between 2014 and 2015 and 2017-2018 were explained in some screening organisations. Removing the possibility for GPs to send invitations explains some of the decline in participation, although this did not account for the total change in attendance.

Abstract
Migrant-origin women are less prone to cervical screening uptake compared with host populations. This study examined cervical cancer screening participation and factors associated with it in the Finnish mass screening program during 2008–2012 in women of Russian, Somali and Kurdish origin compared with the general Finnish population (Finns) in Finland. The study population consists of samples from the Finnish Migrant Health and Well-being Study 2010–2012 and Health 2011 Survey; aged 30–64 (n = 2579). Data from the Finnish screening register linked with other population-based registry data were utilized. For statistical analysis we employed logistic regression. Age-adjusted screening participation rates were Russians 63% (95% CI: 59.9–66.6), Somalis 19% (16.4–21.6), Kurds 69% (66.6–71.1), and Finns 67% (63.3–69.8). In the multiple-adjusted model with Finns as the reference; odds ratios for screening were among Russians 0.92 (0.74–1.16), Somalis 0.16 (0.11–0.22), and Kurds 1.37 (1.02–1.83). Among all women, the substantial factor for increased screening likelihood was hospital care related to pregnancy/birth 1.73 (1.27–2.35), gynecological 2.47 (1.65–3.68), or other reasons 1.53 (1.12–2.08). Screening participation was lower among students and retirees. In conclusion, screening among the migrant-origin women varies, being significantly lowest among Somalis compared with Finns. Efforts using culturally tailored/population-specific approaches may be beneficial in increasing screening participation among women of migrant-origin.

Abstract
High participation in cervical cancer screening is essential for an effective screening program. In this population-based study, we investigated associations between general health, lifestyle and sexual behavior, and non-participation in cervical cancer screening in Denmark. During 2011-2012, a random sample of women aged 18-45 years from the general female population were invited to participate in a survey regarding health, lifestyle and sexual habits. Altogether 18,631 women responded (response rate: 75.1%), of whom 14,271 women aged 23-45 years were included in this analysis. Information on screening participation within four years after response, and data on sociodemographic characteristics, was obtained from nationwide registers. Logistic regression was used to calculate odds ratios (ORs) for non-participation, crude and adjusted for sociodemographic characteristics. Overall, 13.9% of the women were not screened during follow-up. The odds of non-participation was increased in women who were overweight (ORadj. = 1.20; 95% CI, 1.06-1.35), obese (ORadj. = 1.46; 95% CI, 1.27-1.67), perceived themselves as much too fat (ORadj. = 1.50; 95% CI, 1.29-1.74), had poor self-perceived health (ORadj. = 1.22; 95% CI, 1.03-1.45) or smoked daily (ORadj. = 1.81; 95% CI, 1.61-2.03). Conversely, women with previous genital warts or other sexually transmitted infections, and young women with ≥10 lifetime sexual partners or ≥2 new recent partners, had decreased odds of non-participation. In conclusion, obesity, poor self-perceived health and daily smoking were associated with lower participation in cervical cancer screening. Interventions targeting these groups are needed.

Abstract
Cervical cancer (CC) control is based on the implementation of effective screening programs. In the coming years, human papilloma virus vaccination coverage will contribute considerably toward cancer prevention. In Italy, where an organized screening program has been implemented, immigration from low/middle-income countries with a high prevalence of human papilloma virus infections has increased steadily over the last decades. To assess the impact of screening efforts in counteracting background changes, we analyzed the incidence trends of cervical intraepithelial neoplasia grade 3 carcinomas in situ (CIS) and invasive CC from 1994 to 2013 through an Age–Period–Cohort model using data of a regional population-based registry. Moreover, using Joinpoint regression, we compared the incidence of cervical lesions in native women with that observed in foreign-born women, highlighting the differences in age and screening status. The results indicate that the CC incidence trend decreased in Italian women (annual percent change = −2.7*%, 95% confidence interval = −4.3; −1.1), but increased (APC = 12.2*%, 95% confidence interval = 7.6; 17.0) in immigrants. For CIS, incidence rates show a growing trend in both groups, especially in women born abroad. For cancer, no marked changes in period-specific incidence rate ratios were detected until around 2000, when we found a slight decrease, followed by an increase. For CIS, we estimate an important upward trend in cohort-specific risks. The favorable effect of screening in preventing an increase in CC incidence has been counteracted by the progressive increase in immigrants from high-risk countries, where it is of increasing relevance to extend the use of vaccination.

Abstract
OBJECTIVE In 2017, the Australian National Cervical Screening Program changed from two-yearly Pap smears between ages 18 and 69, to five-yearly human papillomavirus screening between ages 25 and 74 (the "Renewal"). This study investigated attitudes towards the changes, among individuals previously affected by cervical abnormalities/cervical cancer, personally or through a friend/relative. METHODS We conducted a thematic analysis of comments expressing personal history or a family/friend history of cervical abnormalities/cervical cancer as a reason for opposing changes to the cervical screening program. The comments were taken from a 20% random sample of 19,633 comments posted on the "Change.org" petition "Stop May 1st Changes to Pap Smears - Save Women's Lives" in February-March 2017. RESULTS There were 831 (20.8%) commenters who reported that they were concerned about a change in screening due to: feelings of increased personal vulnerability to cervical cancer due to their own personal history of cervical abnormalities; comparison of extended screening intervals and later age of first screening to their own experiences; and a perception of increased personal risk due to family history. CONCLUSION Women previously affected by cervical abnormalities or cervical cancer, personally or through a friend/relative, expressed concern about changes to cervical screening due to perceived increased risk and feeling vulnerable due to personal history.

Abstract
BACKGROUND Despite worldwide efforts in encouraging routine pap smears for early detection of cervical cancer, Poland's screening rate lags behind the rest of the European Union at 20.2%. Family physicians (FPs) in Poland rarely perform pap smears, and little is known about the experiences and attitudes of Polish patients regarding pap smear screening in a primary healthcare (PHC) setting. METHODS A cross-sectional questionnaire-based survey was performed. Questionnaires were distributed among 43 FPs and 418 of their patients in one Polish region. The data from patients were associated with the doctors' characteristics. Descriptive statistics, the χ2 test and the Mann-Whitney U test were used for analysis. RESULTS Nearly two-thirds of patients (66%) declared willingness to undergo free pap smear screening by their FPs, with the most common reason being time saved. Among those objecting to receive pap smears from their FPs, immediate specialist care provided by gynaecologists in case of adverse results was the main concern. The factors that positively influenced the patients' decision to undergo cervical cancer screening in PHC were: (1) living in a city with more than 100 000 inhabitants, (2) being single, (3) having a female FP or (4) a physician with specialty training in family medicine. CONCLUSION There is high level of acceptance for pap smears performed in PHC offices among patients in Poland. They are more likely to comply with the screening due to easy access. Establishing a solid physician-patient relationship is also crucial in encouraging screening.

Abstract
Introduction Following years of controversy regarding screening for prostate cancer using prostate-specific antigen, evidence evolves towards a more restrained and preference-based use. This study reports the impact of landmark trials and updated recommendations on the incidence rate of prostate cancer screening by Swiss general practitioners. Methods We performed a retrospective analysis of primary care data, separated in 3 time periods based on dates of publications of important prostate-specific antigen screening recommendations. 1: 2010-mid 2012 including 2 updates; 2: mid 2012-mid 2014 including a Smarter Medicine recommendation; 3: mid-2014—mid-2017 maintenance period. Period 2 including the Smarter Medicine recommendation was defined as reference period. We further assessed the influence of patient’s age and the number of prostate-specific-antigen (PSA) tests, by the patient and within each time period, on the mean PSA concentration. Uni- and multivariable analyses were used as needed. Results 36,800 men aged 55 to 75 years were included. 14.6% had ≥ 2 chronic conditions, 11.7% had ≥ 1 prostate-specific antigen test, (mean 2.60 ng/ml [SD 12.3]). 113,921 patient-years were covered. Data derived from 221 general practitioners, 33.5% of GP were women, mean age was 49.4 years (SD 10.0), 67.9% used prostate-specific antigen testing. Adjusted incidence rate-ratio (95%-CI) dropped significantly over time periods: Reference Period 2: incidence rate-ratio 1.00; Period 1: incidence rate-ratio 1.74 (1.59–1.90); Period 3: incidence rate-ratio 0.61 (0.56–0.67). A higher number of chronic conditions and a patient age between 60–69 years were significantly associated with higher screening rate. Increasing numbers of PSA testing per patient, as well as increasing age, were independently and significantly associated with an increase in the PSA value. Conclusion Swiss general practitioners adapted screening behavior as early as evidence of a limited health benefit evolved, while using a risk-adapted approach whenever performing multiple testing. Updated recommendations might have helped to maintain this decrease. Further recommendations and campaigns should aimed at older patients with multimorbidity, to sustain a further decline in prostate-specific antigen screening practices.

How does information on the harms and benefits of cervical cancer screening alter the intention to be screened?: a randomized survey of Norwegian women. Eur J Cancer Prev 2019; 28:87-95.

Abstract
Cervical cancer (CC) is the 13th most frequent cancer among women in Norway, but the third most common among women aged 25-49 years. The national screening program sends information letters to promote screening participation. We aimed to evaluate how women's stated intention to participate in screening and pursue treatment changed with the provision of additional information on harms associated with screening, and to assess women's preferences on the timing and source of such information. We administered a web-based questionnaire to a panel of Norwegian women aged 25-69 years and randomized into three groups on the basis of when in the screening process additional information was introduced: (i) invited for routine screening, (ii) recommended an additional test following detection of cellular abnormalities, and (iii) recommended precancer treatment. A fourth (control) group did not receive any additional information. Results show that among 1060 respondents, additional information did not significantly alter women's stated intentions to screen. However, it created decision uncertainty on when treatment was recommended (8.76-9.09 vs. 9.40; 10-point Likert scale; P=0.004). Over 80% of women favored receiving information on harms and 59% preferred that information come from a qualified public health authority. Nearly 90% of women in all groups overestimated women's lifetime risk of CC. In conclusion, additional information on harms did not alter Norwegian women's stated intention to screen for CC; yet, it resulted in greater decision uncertainty to undergo precancer treatment. Incorporating information on harms into invitation letters is warranted as it would increase women's ability to make informed choices.

Abstract
High coverage is essential for the effectiveness of national screening programmes. Identifying non-screeners across different screening programmes may help inform strategies to improve uptake. This study aims to analyse the association between previous cervical cancer screening (CCS) coverage and participation in breast cancer screening (BCS). This historical register-based cohort study included 91,787 Danish women aged 50-64 years who were invited to participate in the first organised round of BCS in the Central Denmark Region (CDR) in 2008-09. CCS coverage was defined as having a smear registered in the 5 1/2 years preceding the BCS, and BCS participants were divided into participants and non-participants and further categorised as active non-participants (ANP) if they cancelled and passive non-participants (PNP) if they abstained from the appointment. Of all 91,787 women included in the study, 62,391 (68%) were covered both by CCS and participated in BCS. Women not covered by CCS were more likely to be non-participants in BCS than women covered by CCS (PRRadjusted = 2.80, 95% CI: 2.68-2.93). Both PNP (PRRadjusted = 3.99, 95% CI: 3.80-4.19) and ANP (PRRadjusted = 2.50, 95% CI: 2.34-2.68) were more likely not to be covered by the CCS. In conclusion, non-coverage by CCS was strongly associated with nonparticipation in BCS. Specific groups of women only participated in one screening programme. To increase uptake, future interventions may specifically target these groups.

Abstract
Background Cervical cancer (CC) incidence in Estonia is the third highest in Europe, even though an organised nation-wide screening program has been in place since 2006. The aim of the study was to analyse the incidence and survival of CC in Estonia, focusing on age, morphology and stage at diagnosis. Methods Data from Estonian Cancer Registry were used to analyse age-standardized (world) and age-specific incidence for 1968–2014 rates. Joinpoint regression was used to estimate the annual percentage change (APC) for incidence trends. Age-period-cohort model was used to summarise time trends in terms of cohort and period effects. Relative survival ratios (RSR) were calculated for cases diagnosed in 1995–2014. Union for International Cancer Control version 7 of the TNM classification for malignant tumours was used to categorise stage. Results The age-standardized incidence of CC increased since 1980s at a rate of 0.8% per year. A significant increase was seen for all age groups except for 70+. The incidence of squamous cell carcinoma mimicked the overall trend, while adenocarcinoma showed increase since mid-1990s (APC 6.7). Age-period-cohort modelling showed strong cohort effects with the lowest risk for birth-cohorts born around 1940 and significantly increasing risks for successive cohorts born thereafter. No period effects were seen. The proportion of stage IV cases increased from 13% in 2005–2009 to 18% in 2010–2014. A significant increase was seen in the overall 5-year RSR from 1995 to 1999 to 2010–2014 (58% vs 66%). In 2010–2014, the 5-year RSRs ranged from 89% in women aged 15–39 to 41% in age group 70+. For stages I to IV, the respective RSRs were 98, 74, 57 and 22%. Conclusions The inadequate uptake and insufficient quality of the Pap-smear based screening program has not brought along a decline in the incidence of CC in Estonia. Stage distribution has shifted towards later stages. New approaches are needed to prevent CC in Estonia.

Abstract
Cancer survival is an important indicator for quality of cancer care. We sought to determine if there are differences in cancer survival between immigrants and the host population in Norway. We performed a nationwide registry-based study comprising subjects diagnosed with cancer between 1990 and 2014, and followed until the end of 2016. Survival was estimated for 13 cancer sites with cause-specific survival. Adjustments were made for common confounders (age, sex, year of diagnosis and place of residence) and defined mediators (stage at diagnosis, comorbidity and socioeconomic factors). A total of 500,255 subjects were available for analysis, of which 11,252 were Western and 8,701 non-Western immigrants. We did not find differences in cancer survival between Western immigrants and Norwegians, while non-Western immigrants, with some exceptions, had similar or better survival. Better lung cancer survival in non-Western immigrants than Norwegians was notable (hazard ratio (95% confidence interval): 0.78 (0.71-0.85)), and not explained by defined mediators. Immigrants from Eastern Europe and Balkan with melanoma (hazard ratio: 1.54 (1.12-2.12)) and prostate cancer (hazard ratio: 1.34 (1.08-1.67)), and possibly from sub-Saharan Africa with breast cancer (hazard ratio: 1.41 (0.94-2.12)) had worse survival than Norwegians. The results suggest that immigrants in Norway have good cancer survival relative to the host population. Poor survival in immigrants from Eastern Europe and Balkan with melanoma and prostate cancer, and sub-Saharan Africa with breast cancer might be a concern.

Abstract
Background Immigrants from certain low- and middle-income countries are more prone to cancers attributed to viral infections in early life. Cervical cancer is caused by human papillomavirus but is highly preventable by regular screening. We assessed participation among immigrants in a population-based cervical screening programme and identified factors that predicted non-adherence within different immigrant groups. Methods We used data from several nationwide registries. The study population consisted of 208 626 (15%) immigrants and 1 157 223 (85%) native Norwegians. Non-adherence was defined as no eligible screening test in 2008–12. We estimated prevalence ratios with 95% confidence intervals (CIs) for factors associated with non-adherence by modified Poisson regression. Results In total, 52% of immigrants were not screened. All immigrants showed 1.72 times higher non-adherence rates (95% CI 1.71–1.73) compared with native Norwegian women when adjusted for age and parity. The proportion of non-adherent immigrants varied substantially by region of origin and country of origin. Being unemployed or not in the workforce, being unmarried, having low income and having a male general practitioner was associated with non-adherence regardless of region of origin. Living <10 years in Norway was an evident determinant of non-adherence among most but not all immigrant groups. Conclusions An increasing proportion of immigrants and low screening participation among them pose new public health challenges in Europe. Immigrants are diverse in terms of their sociodemographic attributes and screening participation. Tailored information and service delivery may be necessary to increase cancer screening among immigrants.

Abstract
Cervical cancer occurs most often in under-screened women. In this nationwide register study, we described differences in sociodemographic characteristics between passive and active non-participants and examined socio-demographic characteristics, reproductive history, and mental and physical health as potential determinants for passive non-participation compared with participation in the Danish cervical cancer screening program. Screening history in women aged 23-49 years invited for cervical cancer screening in 2008-2009 was retrieved from the Danish Pathology Databank with information about dates of invitation and unsubscription. We identified participants (n = 402,984), active non-participants (n = 10,251) and passive non-participants (n = 63,435) within four years following baseline invitation and retrieved data about the study population from high-quality registries. We examined differences in socio-demographic characteristics of passive and active non-participants, and used multiple logistic regression analyses to identify potential determinants of passive non-participation. We found that active and passive non-participants differed in relation to socio-demography. When compared with screening participants, the odds of passive non-participation was increased in women who originated from less developed countries; were unmarried; had basic education or low income; had four or more children; smoked during pregnancy; had multiple induced abortions; or had a history of obesity, intoxicant abuse or schizophrenia or other psychoses. In conclusion, in this nationwide, prospective, population-based study, differences in socio-demographic characteristics between passive and active non-participants were found. Furthermore, sociodemography, reproductive history, and mental and physical health were determinants for passive non-participation. Addressing inequalities in screening attendance may help to further decrease the incidence of and mortality from cervical cancer.

Abstract
As a new initiative, HPV self-sampling to non-attenders using the dry Evalyn self-sampling brush is offered in the Capital Region of Denmark. The use of a dry brush is largely uncharted territory in terms of analytical stability. In this study we aim to provide evidence on the analytical quality of dry HPV self-sampling brushes as a function of time and temperature. We assessed the analytical stability of dry stored Evalyn brushes at three different temperatures, (4 °C, room temperature, 30 °C) and five different storage time points; T = 0 (baseline), 2, 4, 8, 16, and 32 weeks prior to HPV analysis using the BD Onclarity HPV assay. Mean Ct value of the Onclarity internal control was used as comparator of cellularity across time and temperatures, with no or only borderline statistical differences observed. HPV detection was stable throughout the five time points. In addition, analytically amplifiable DNA copy numbers and DNA fragmentation was assessed using the Agena iPLEX Exome QC assay, with no or only borderline statistical differences observed. In conclusion, the Evalyn brush is analytically stable with respect to human genomic material and HPV detection for up to 32 weeks at temperatures ranging from 4 °C to 30 °C. The Capital Region of Denmark is implementing HPV self-sampling using a dry brush. But how analytically stable is a dry collected self-sampling device? Stability was established for both human DNA (all, N = 637) and HPV (positives, N = 41). We found the Evalyn Self-sampling brush stable up to 6 month. Neither 4 °C nor 30 °C changed the analytical stability of the dry brush.

Safety and acceptability of human papillomavirus testing of self-collected specimens: A methodologic study of the impact of collection devices and HPV assays on sensitivity for cervical cancer and high-grade lesions. J Clin Virol 2017; 99-100:22-30. [PMID: 29289814 DOI: 10.1016/j.jcv.2017.12.008] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2017] [Revised: 12/08/2017] [Accepted: 12/15/2017] [Indexed: 12/25/2022]
Abstract
BACKGROUND Comparative data on different self-collection methods is limited. OBJECTIVES To assess the impact of hrHPV testing of two self-collection devices for detection of cervical carcinoma and high-grade lesions. STUDY DESIGN Three hundred ten patients collected two cervicovaginal specimens using a brush (Evalyn®Brush) and a swab (FLOQSwabs™), and filled a questionnaire at home. Then, a physician at the clinic took a cervical specimen into PreservCyt® buffer for hrHPV testing and cytology. All specimens were tested using Anyplex™ II HPV28, Cobas® 4800 HPV Test and Xpert®HPV. RESULTS Performance comparison included 45 cervical carcinomas and 187 patients with premalignant lesions. Compared to the physician-specimen, hrHPV testing of Evalyn®Brush showed non-inferior sensitivity for CIN3+ (relative sensitivity of Anyplex™ 0.99; Cobas® 0.96; Xpert®HPV 0.97) while hrHPV testing of FLOQSwabs™ showed inferior sensitivity (relative sensitivity of Anyplex™ 0.91; Cobas® 0.92; Xpert®HPV 0.93). Similar results were observed for invasive carcinomas albeit that FLOQSwabs™ was statistically non-inferior to the physician-specimen. Self-collection by either Evalyn®Brush or FLOQSwabs™ was more sensitive for CIN3+ than LSIL or worse cytology. Significant decrease in sensitivity for CIN3+ were observed for FLOQSwabs™ when specimens were preprocessed for hrHPV testing after 28 days. Both devices were well accepted, but patients considered Evalyn®Brush easier and more comfortable than FLOQSwabs™. CONCLUSIONS Self-collection is comparable to current screening practice for detecting cervical carcinoma and CIN3+ but device and specimen processing effects exist. Only validated procedure including collection device, hrHPV assay and specimen preparation should be used.

Inequalities in cervical cancer screening utilisation and results: A comparison between Italian natives and immigrants from disadvantaged countries. Health Policy 2017; 121:1072-1078. [PMID: 28843514 DOI: 10.1016/j.healthpol.2017.08.005] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2016] [Revised: 01/04/2017] [Accepted: 08/03/2017] [Indexed: 11/28/2022]
Abstract
Cervical cancer screening underutilisation is documented among immigrants from poor countries and it is associated to an augmented risk for severe lesions. In a cohort of 1,410,364 Italian women and 200,491 immigrants from poor countries differences in screening participation and results were investigated. Participation rate was lower for immigrants than for Italians: 43.98% versus 48.59% (chi(1): p<0.001). This gap increased with age (ptrend<0.0001). Some socio-demographic factors negatively influenced immigrants' participation. Illiteracy (OR=0.75) versus secondary school, being single (OR=0.71) versus attached, first screens (OR=0.67) versus subsequent ones. Although the interaction between educational and professional levels showed that graduated immigrant women conducting an intellectual job have a higher inclination towards screening than their Italian peers (OR=1.43 vs OR=1.04). The Standardised Detection Ratio (SDR) suggested a frequency of severe lesions nearly double among immigrants in first screens (SDR=1.94; 95% CI: 1.82-2.08) and even higher (SDR=2.53; 95% CI: 2.35-2.73) for Central/Eastern Europeans. Multi-component interventions involving both patients and providers offer the greatest potential to increase cervical cancer screening uptake within foreign-born populations. So immigrant-specific interventions are needed for some immigrant groups, like Central/Eastern Europeans who are at higher risk of cervical lesions and, together with Asians and Africans, showed a poor attitude towards cancer prevention.
