Cervical cancer screening coverage, management of squamous intraepithelial lesions and related costs in France.

Until 2018, cervical cancer screening in France was an unorganized individual screening, with the exception of some pilot programs in some territories. We aimed to assess, before the implementation of organized cervical cancer screening and human papillomavirus (HPV) nonavalent vaccine introduction in the vaccination schedule in 2018, (i) the individual cervical cancer screening coverage, (ii) the management of squamous intraepithelial lesions (SIL) and (iii) the related costs. We used the Système National des Données de Santé (SNDS) (Echantillon Généraliste de Bénéficiaires [EGB] and Programme de Médicalisation des systèmes d’information [PMSI]) to assess the cervical screening coverage rate in France between January 1st, 2012 and December 31st, 2014, and to describe diagnostic investigations and therapeutic management of SIL in 2013. After extrapolation to the general population, a total of 10,847,814 women underwent at least one smear test over the 3-year study period, corresponding to a coverage rate of 52.4% of the women aged 25 to 64 included. In 2013, 126,095 women underwent HPV test, 327,444 women underwent colposcopy, and 9,653 underwent endocervical curettage; 31,863 had conization and 12,162 had laser ablation. Besides, 34,067 women experienced hospital stays related to management of SIL; 25,368 (74.5%) had high-grade lesions (HSIL) and 7,388 (21.7%) low-grade lesions (LSIL). Conization was the most frequent in-hospital therapeutic procedure: 89.5% (22,704) of women with an in-hospital procedure for HSIL and 64.7% (4,781) for LSIL. Mean cost of smear test, colposcopy and HPV tests were around 50€. Total cost for hospital stays in 2013 was estimated at M41€, or a mean cost of 1,211€ per woman; 76% were due to stays with HSIL. This study highlights the low coverage rate of individual cervical cancer screening and a high burden related to SIL management.

Projected time to elimination of cervical cancer in the USA: a comparative modelling study

In May, 2018, the Director-General of WHO issued a global call to eliminate cervical cancer as a public health problem, which will involve ambitious screening and vaccination coverage targets. We aimed to assess the potential for, and timing of, cervical cancer elimination in the USA and whether this could be expedited by adopting ambitious coverage targets, using two cervical cancer simulation models. In this modelling study, we used two independently-developed cervical cancer microsimulation models-Harvard and Policy1-Cervix-to estimate changes in the incidence of human papillomavirus (HPV)-induced cervical cancer over time in the USA, including herd effects from vaccination. We compared nine alternative scenarios for prophylactic HPV vaccination and cervical screening scale-up with a status quo scenario that involved no additional interventions in the context of a threshold for cervical cancer elimination of four or fewer cases per 100 000 women-years. We also estimated the number of cervical cancer cases that could be averted between 2019 and 2100 associated with the adoption of ambitious goals for cervical cancer screening and vaccination coverage, and other potential strategies. Under status quo assumptions, the Havard and Policy1-Cervix models projected that cervical cancer incidence would decrease to less than four or fewer new cases per 100 000 women-years by the 2038 and 2046, respectively. Scaling up screening coverage to 90% in 2020, was the most effective intervention to expedite time to elimination (10-13-year reduction), averting a mean of 1400-2088 additional cases annually between 2019 and 2100. Increasing HPV vaccination coverage to 90% or vaccinating adults aged 26-45 years had relatively little effect on cervical cancer incidence. Sensitivity analysis using different population structures resulted in differences in time to elimination (range -10 years to +27 years) compared with status quo predictions. The USA is on track to eliminate cervical cancer as a public health problem in the next two to three decades. Time to elimination could be expedited by 10-13 years by achieving higher screening coverage. Targeting of underscreened and under-vaccinated women remains key to achieving cervical cancer elimination for all women. US National Cancer Institute.

Cervical Cancer Screening Rates Among Chinese Women - China, 2015.

What is already known about this topic? Cervical cancer is the fourth most common cancer of women around the world. Age-adjusted incidence and mortality rates of cervical cancer were 11.78 and 3.29 per 100,000, respectively, in China in 2015. What is added by this report? Cervical cancer screening rates were 25.7% for women aged 20–64 years old and 31.4% for women aged 35–64 years old in China in 2015. Screening rates were lower in rural areas than in urban areas and varied across provinces. What are the implications for public health practice? Efforts should be made to continue to strengthen national and local policy initiatives, financial support, health education, and accessibility to women in rural areas for cervical cancer screening coverage.

Improvement in contraceptive coverage and gynecological care of adult women with cystic fibrosis following the implementation of an on-site gynecological consultation

ObjectiveOur study aimed to evaluate the impact of the introduction of a new gynecologic referral service in our adult Cystic Fibrosis (CF) center on contraceptive coverage, gynecological follow-up regularity, and cervical cancer screening coverage. Study designWe implemented an on-site gynecological consultation in our adult CF center in 2015. We compared the results of two surveys conducted successively in 2014 and in 2017 in a cohort of women with CF attending the Lyon CF center. Women completed the same self-report written questionnaire as in 2014. Main outcome measures were the comparisons of contraceptive coverage, gynecological follow-up regularity, and cervical cancer screening coverage between 2014 and 2017. ResultsAll the 136 women (100%) who attended the clinic in 2017 participated. Contraceptive prevalence rate increased from 69%(CI95%:60.3–78.1) to 86%(CI95%:79.6–92.9) between 2014 and 2017 (p = 0.005). Among transplanted patients, the contraceptive prevalence rate was 92.3%(CI95%:82.0–100) in 2017. Long acting reversible contraceptive use markedly increased from 10% to 21.6% (p = 0.005). The proportion of women that reported an access to gynecological care increased between 2014 and 2017 (74%(CI95%:66.3–82.0) vs 91%(CI95%:86.9–95.4), p < 0.005) and reached 100% among transplanted patients. Cervical cancer screening improved (55%(CI95%:51.2–68.8) vs 85%(CI95%:78.6–90.6) women ever screened) (p < 0.0005) and reached 100% among transplanted patients. ConclusionsWe observed an improvement in contraceptive coverage and gynecological care of adult women with CF following the implementation of a dedicated gynecological consultation in the CF center. ImplicationsService linkages and formal links between CF centers and gynecologists can facilitate access to disease-specific contraceptive counseling, adequate gynecological management and cervical cancer screening.

Cervical cancer screening service utilization and associated factors among age-eligible women in Jimma town using health belief model, South West Ethiopia

BackgroundCervical cancer is the second most common gynecologic cancer affecting the lives of women. It causes hundreds of thousands of death among women annually worldwide. When a woman is screened for cervical cancer at least once in her life between the ages of 30 and 40, the risk of getting cervical cancer can be decreased by 25–36%. Despite this advantage, the coverage of cervical cancer screening is limited in low and middle-income countries including Ethiopia.ObjectiveTo assess cervical cancer screening service utilization and associated factors among age-eligible women in Jimma town, South West Ethiopia, 2017.MethodsCommunity based cross-sectional study was used. Seven hundred thirty-seven women were selected using systematic random sampling. Data were collected using a structured interview administered questionnaire. Data were collected on socio-demographic, reproductive factors, knowledge of cervical cancer as well as constructs of Health belief model and practice related variables. Logistic regression analysis was performed, and variables with a p-value of less than 0.05 in the multivariable analysis were taken as statistically significant predictors of cervical cancer screening service utilization.ResultsOf the 737 women, only 15.5% were screened for cervical cancer. The independent predictors of cervical cancer screening utilization were: being government employee [AOR = 3.00, 95% CI: 1.49–6.01], knowing someone who has ever screened [AOR = 3.61, 95% CI: 2.07–6.29], having history of gynecologic examination for any reason (having previous examination that expose women genitalia for physician like examination during child birth, abortion procedure and examination for STI) [AOR =2.84, 95% CI: 1.48–5.45], not preferring gender of physician for gynecological examination [AOR = 3.57, 95% CI: 1.98–6.45], getting advice from health care providers [AOR = 4.45, 95% CI: 2.57–7.70], having good knowledge of cervical cancer screening [AOR = 3.46, 95% CI: 1.47–8.21] and having perceived susceptible for cervical cancer [AOR = 3.03, 95% CI: 1.64–5.56].ConclusionsThe utilization of cervical cancer screening services was low in Jimma town. Strengthening the screening service is important through raising the awareness of the community towards cervical cancer and screening services.

A roadmap for a comprehensive control of cervical cancer in Poland: integration of available solutions into current practice in primary and secondary prevention.

In Poland, cervical cancer incidence and mortality still remain considerably higher than in Western European countries or North America. Recent data indicate decreasing trends in women younger than 60 years and stable trends in older women. In this article, we identified obstacles in primary and secondary prevention of cervical cancer in Poland. We analysed local legislation, management structure and organization of cervical cancer prevention in Poland and reviewed solutions available and implemented in other European countries. The main weaknesses include: (i) very low coverage of organized screening; concurrent unregistered opportunistic screening with unknown coverage and high test consumption (ii) suboptimal quality assurance in organized screening and no external quality assurance in opportunistic screening (iii) very low coverage of human papillomavirus vaccination that is not centrally reimbursed (iv) absence of pilot evaluation of (a) interventions that may improve population coverage and (b) performance of new preventive strategies. The proposed solutions are multifaceted and involve: (i) legislative and organizational regulation of cervical cancer screening aimed at comprehensive registration of procedures, data access and quality assurance (ii) pilot testing and implementation of new ways to increase coverage of cervical cancer screening, in particular among older women (iii) pilot evaluation with possible introduction of human papillomavirus-based screening and (iv) inclusion of human papillomavirus vaccination into the reimbursed national immunization program.

Organised Versus Opportunistic Cervical Cancer Screening in Urban and Rural Regions of Lithuania.

Background and Objectives: In 2004, Lithuania started the Nationwide Cervical Cancer Screening Programme. However, screening is more opportunistic than population-wide and the programme’s coverage is insufficient. The aim of this study was to assess the effect of systematic personal invitation on coverage of cervical cancer (CC) screening in urban and rural regions of Lithuania. Materials and Methods: The study was conducted in an urban primary healthcare centre (PHCC) and in a rural PHCC, where prevailing CC screening practice was highly opportunistic. Over the first year, all women aged 25–60 who had not received a Pap smear test within the last three years in urban (n = 1591) and rural (n = 1843) PHCCs received a personal invitation letter to participate in the screening. Over the second year, the reminder letter was sent to the non-attendees (n = 1042 in urban and n = 929 in rural PHCCs). A random sample of women (n = 93), who did not attend for screening after two letters, was contacted by phone in order to identify the barriers of non-attendance. Results: Before the study, only 9.6% of the target population in urban and 14.7% in rural PHCCs participated in CC screening. After the first invitation letter, the participation in CC screening increased up to 24.6% in urban and 30.8% in rural areas (p < 0.001). After the reminder letter, the attendance was 16.4% in urban and 22.2% in rural PHCCs (p < 0.001). The most common barriers for the non-attendance were lack of time, long waiting time for family doctor’s appointment, worries that a Pap test might be unpleasant and preventive gynaecological examination outside of the screening program. Conclusions: A systematic personal invitation with one reminder letter significantly increased the coverage of CC screening and was more effective in rural regions than in urban regions. The assessed barriers for non-attendance can be used to improve the coverage of screening.

General practitioners who never perform Pap smear: the medical offer and the socio-economic context around their office could limit their involvement in cervical cancer screening

BackgroundIn France, with the growing scarcity of gynecologists and a globally low and socially differentiated coverage of cervical cancer screening (CCS), general practitioners (GPs) are valuable resources to improve screening services for women. Still all GPs do not perform Pap smears. In order to promote this screening among GPs, the characteristics of physicians who never perform CCS should be more precisely specified. Besides already-known individual characteristics, the contextual aspects of the physicians’ office, such as gynecologist density in the area, could shape GPs gynecological activities.MethodsTo analyze county (département) characteristics of GPs’ office associated with no performance of CCS, we used a representative sample of 1063 French GPs conducted in 2009 and we constructed mixed models with two levels, GP and county.ResultsAlmost 35% (n = 369) of the GPs declared never performing CCS. GPs working in counties with a poor GP-density per inhabitants were more likely to perform CCS (odds ratio (OR) = 0.52 for each increase of density by 1 GP per 10,000 inhabitants, 95% confidence interval (CI) = 0.37–0.74). On the contrary, GPs working in counties with an easier access to a gynecologist were more likely not to perform CCS (OR = 1.06 for each increase of density by 1 gynecologist per 100,000 women, 95%CI = 1.03–1.10 and OR = 2.02 if the first gynecologist is reachable in less than 15 min, 95%CI = 1.20–3.41) as well as GPs working in areas with a poverty rate above the national average (OR = 1.66, 95%CI = 1.09–2.54). These contextual characteristics explain most of the differences between counties concerning rates of not performing CCS.ConclusionsSpecific programs should be developed for GPs working in contexts unfavorable to their involvement in CCS.

Cervical cancer screening uptake and correlates among HIV-infected women: a cross-sectional survey in Côte d’Ivoire, West Africa

Genital self-sampling for HPV-based cervical cancer screening: a qualitative study of preferences and barriers in rural Ethiopia

BackgroundIn the context of WHO’s “task shifting” project and growing global consensus on primary HPV-based cervical cancer screening, self-sampling is a promising new tool to expand screening access, uptake and coverage for women worldwide. We aimed to explore perceptions and acceptability of HPV self-sampling-based cervical cancer screening among community members and health professionals in rural northwest Ethiopia and to identify preferences and socio-cultural barriers regarding self-sampling in order to design a suitable high-coverage screening intervention for a rural African setting.MethodsFour community-based focus group discussions (FGD) were conducted in the rural district of Dabat, Northwest Ethiopia, each comprising 8 to 14 female participants, counting a total of 41 participants. The groups were homogenously composed in terms of their socio-economic status in the community. They included health centre attendees, community members, nurses and health development army leaders (HDAL). Two qualitative data collection experts conducted the interviews in the local language, using a FGD guide with several thematic areas. All participants granted written informed consent prior to the conduct of the interviews. As a concrete example of an existing self-sampling approach for cervical cancer screening we used the Evalyn® Brush.ResultsEmerging themes included (i) misconceptions and low awareness about cervical cancer among community residents and primary health care providers in rural northwest Ethiopia, (ii) stigmatization and social exclusion of affected women, (iii) delay in seeking of health care due to poor access and availability of services, and lacking of a concept of early cancer prevention, (iv) need of spousal permission, (v) fear of financial burden and (vi) fear of social marginalization. The self-sampling device was regarded to be acceptable and was judged to be easy to use for most women. The existing Ethiopian health care structure could facilitate a community approach.ConclusionHome-based self-sampling for cervical cancer screening is a socially acceptable and feasible “task shifting” method that will increase cervical cancer screening access and coverage in the Ethiopian study community. Education, awareness creation, community mobilization and family inclusion are identified as key activities to promote, implement and facilitate “task shifting” approaches like self-sampling.

Temporal changes in breast cancer screening coverage provided under the Brazilian National Health Service between 2008 and 2017

BackgroundIn Brazil, 70% of the population depends on the public healthcare system. Since early detection is considered crucial, this study aimed to evaluate temporal changes in breast cancer screening coverage provided under the Brazilian National Health Service (SUS) according to the different regions of the country between 2008 and 2017.MethodsThis ecological study analyzed data on breast cancer screening within the SUS for women aged 50–69 years. Coverage was calculated from the ratio between the number of screening tests conducted and the expected number for the target population. Joinpoint regression analysis was used to calculate annual percent changes (APC) in coverage.ResultsAround 19 million mammograms were performed in 50–69-year old women within the SUS between 2008 and 2016. The estimated APC indicates that breast cancer screening coverage increased by 14.5% annually in Brazil between 2008 and 2012 (p < 0.01), with figures stabilizing between 2012 and 2017 as shown by an APC of − 0.4% (p = 0.3). In the five geographic regions of the country, the APC initially increased, then stabilized in the north, northeast and southeast and decreased in the south and Midwest. Of the 26 states, coverage increased in seven and remained stable in six. In the other 13, there was an initial increase followed by stabilization in 11, and a reduction in coverage in two. In the Federal District, coverage remained stable throughout the study period.ConclusionEvaluation of the temporal changes in breast cancer screening coverage provided under the Brazilian National Health Service revealed an initial increase, confirming that public policies were effective, although insufficient to ensure organized screening. There appears to be a lack of uniformity between the different regions and states and this situation is highlighted in the final 5-year period, with the APC reflecting stabilization of breast cancer screening coverage.

Cervical cancer screening knowledge and barriers among women in Addis Ababa, Ethiopia.

IntroductionRoutine cervical screening has been shown to greatly reduce both the number of new cervical cancers diagnosed each year and the number of deaths resulting from the disease. Nevertheless, cervical screening knowledge and screening uptake is very low in developing countries. In Ethiopia, the coverage of cervical cancer screening is only 1%. In this study, we aimed to assess cervical cancer screening knowledge and barriers for screening uptake among women in Addis Ababa Ethiopia.MethodsA facility-based cross-sectional study was conducted from February to March 2015 in Addis Ababa, Ethiopia. A total of 520 women were selected by a multi-stage sampling procedure. Interview based questioner was used to collect the data. Descriptive statistics was used to describe the socio-demographic and clinical profiles of the women. Multivariate logistic regression using adjusted odds ratio (AOR) and 95% confidence interval (CI) was used to identify independent predictors for cervical screening knowledge. A p-value of <0.05 was set to determine level of statistical significance.ResultsAmong all women, 42.7% had heard of cervical cancer screening and 144 (27.7%) women had adequate knowledge of cervical cancer screening. The mean (±SD) age of women was 27.7 (±5.49) years. In total, a quarter (25%) of eligible women had experience of cervical cancer screening. Not being married (adjusted odds ratio (AOR) = 1.8, 1.1–3.3), having an awareness of cervical cancer (AOR = 5.0, 2.7–9.1) and receiving information from health professionals (AOR = 1.9, 1.1–3.2) were the predictors for good cervical cancer screening knowledge. An absence of symptoms (57%), a lack of knowledge about screening (56.3%) and the lack of a screening service in their living area (42.2%) were the perceived barriers for screening uptake.ConclusionsCervical screening knowledge was low among women and less than half had heard of screening. Women also had low experience of screening. The lack of a screening service, the absence of symptoms and not knowing about screening were the perceived reasons for the low uptake. Hence, awareness campaigns and education should be undertaken by health professionals. Access and availability of screening service is also essential to improve screening uptake.

Mammography Coverage and Tumor Stage in the Opportunistic Screening Context

IntroductionThe increment of breast cancer screening coverage should lead to an increase in the proportion of early tumors diagnosed and the decrease of the cancer-related mortality. However, the effectiveness of opportunistic mammography screening is not well documented for public health systems in middle-income countries. Patients and MethodsWe conducted an ecologic study to evaluate the association of mammography coverage with trends in breast cancer stage distribution. We used data from a total of 42,850 breast cancer patients, diagnosed between 2000 and 2016, combined with estimated mammography coverage from 3 surveys (2003, 2008, and 2013). ResultsBiannual mammography coverage increased from 62.4% in 2003 to 73.9% in 2013. From 2000 to 2016, the proportion of in situ tumors increased 6.9%, the proportion of localized tumors increased 3.9%, the proportion of regional tumors decreased 6.9% and the frequency of distant tumors decreased 4% (P < .00001). ConclusionMammography coverage in the context of opportunistic breast cancer screening was associated with the increase of in situ and localized tumors and decrease of regional and distant tumors.

Evaluation of the self-sampling for cervical cancer screening in Bolivia

BackgroundIncidence and mortality rates of cervical cancer in Bolivia are the highest in Latin America. Vaginal cell self-sampling can improve screening coverage. Information on common reasons for low screening coverage and preferences for future screening are essential to reduce cervical cancer incidence. We aimed to evaluate the knowledge about human papillomavirus (HPV) and cervical cancer of Bolivian women from urban, peri-urban and rural areas of Cochabamba and to determine their degree of acceptability and confidence towards vaginal HPV self-sampling. In addition, we assessed the impact of self-sampling on cervical cancer screening coverage in a selected peri-urban area.MethodsWe gathered information from women living in urban, peri-urban and rural areas of Cochabamba province in Bolivia using two different structured questionnaires. In Survey1, we collected information from 222 women about their knowledge on HPV and cervical cancer. In Survey 2, the acceptance and confidence towards vaginal HPV self-sampling compared to the physician-sampling was assessed in 221 women. A non-probabilistic stratified sampling by areas was carried out for the two questionnaires. In the third phase of the study, we determined the impact of HPV self-sampling collection on screening coverage in a peri-urban area of Cochabamba.ResultsBolivian women knew little or nothing about cervical cancer and HPV infection in all areas. They all found self-sampling collection easier to perform (86.9 to 93.2%) and more comfortable (79.4 to 83.3%) compared to physician sampling. Sampling accuracy to detect cervical cancer was probably higher in their point of view when it was taken by physician (35.1 to 63.5%). However in rural areas women preferred self-sampling. Accordingly, the campaign of vaginal HPV self-sampling in this peri-urban area increased screening coverage, reaching in three months the annual rate average.ConclusionsThe knowledge about cervical cancer and HPV infection is poor in Bolivia. Despite greater acceptance of the vaginal HPV self-sampling in all areas, women kept greater confidence in the screening performed by the gynecologist although HPV self-sampling improved coverage rate.

Establishing Baseline Cervical Cancer Screening Coverage - India, 2015-2016.

Cervical cancer is the second leading cause of new cancer cases and cancer-related deaths among women in India, with an estimated 96,922 new cases and 60,078 deaths each year.* Despite the availability of effective low-cost screening options in India, limited access to screening and treatment services, diagnosis at a later stage, and low investment in health care infrastructure all contribute to the high number of deaths (1). In 2016 the Ministry of Health and Family Welfare of India recommended cervical cancer screening using visual inspection with acetic acid every 5 years for women aged 30-65 years (per World Health Organization [WHO] guidelines) (2,3). To establish a baseline for cervical cancer screening coverage, survey data were analyzed to estimate the percentage of women aged 30-49 years who had ever been screened for cervical cancer (defined as ever having had a cervix examination). Cervical cancer screening was estimated using data from the Fourth National Family Health Survey† (NFHS-4), a nationally representative survey conducted at the district level during 2015-2016, which included 699,686 Indian women aged 15-49 years. Lifetime cervical cancer screening prevalence was low (29.8%) and varied by geographic region, ranging from 10.0% in the Northeast Region to 45.2% in the Western Region. Prevalence of screening was higher among women with higher levels of education and household wealth, those who had ever been married, and urban residents. This screening prevalence can be used as a baseline indicator for cervical cancer screening in India in accordance with the WHO Noncommunicable Diseases Global Monitoring Framework during state-based programmatic rollout and program evaluation (4).

Factors associated with breast cancer screening awareness and practices of women in Addis Ababa, Ethiopia

BackgroundBreast cancer is a global health problem being the most common cancer of women in both developed and under-developed countries. Public and individual awareness can play a vital role in the prevention, early diagnosis and treatment of breast cancer. However evidence is sparse on awareness and practice of breast cancer screening methods used among women of reproductive age in Ethiopia. The present study was designed to determine factors associated with breast cancer screening awareness and practices of women in Addis Ababa.MethodsA facility based cross-sectional study was conducted among women who came for maternal and child health care services to selected public health centers. The participants were interviewed using a structured questionnaire. Following data collection, data entry and analysis was done using Epi-Info version 7and SPSS Version 21 respectively. Cross tabulation of each independent variable with the dependent variable with their 95% confidence interval was done and those variables associated at binary logistic regression with a significance level of 0.2 were entered into multiple logistic regression.ResultsAbout half (53%) of women have heard about breast cancer and 35.5% of women are aware of at least one breast cancer screening method. Among those who are informed about breast cancer screening, 97% indicated that screening improves the chance of survival. Among the common screening methods; self-breast examination, clinical-breast examination and mammographic examination were practiced by 24.3%, 7.6% and 3.8% of respondents, respectively. Women who had high level of income were about 3 times more likely to be aware about breast cancer screening methods, [AOR = 2.5; 95%CI (1.04–-5.91)], while women who attended secondary and tertiary school were 2 and 4 times more likely to practice breast cancer screening methods [AOR = 2.46; 95% CI (1.12–-5.38)] and [AOR = 4.00; 95% CI(1.48–-10.86)] respectively.ConclusionThis study has showed that self-reported breast cancer screening coverage is low. About two-thirds of women had no information about breast cancer screening methods.

Prophylactic human papilloma virus vaccines launch the era of comprehensive cervical cancer control

The etiology of cervical cancer has been fully demonstrated. Different screening strategies are available for different areas with various level of development. The prophylactic human papilloma virus (HPV) vaccine has launched the era of comprehensive cervical cancer control, which is the milestone in the history of human fighting against cancer. However, cervical cancer is still a major public health issue in the world, especially in developing countries. The main challenge lies in the improvement for the coverage of cervical cancer screening and HPV vaccination. Especially for China with large population, various level of the economic development, and the HPV vaccine later than the world for ten years, how to improve the coverage of cervical cancer screening and HPV vaccination? There is a long way to go for the elimination of cervical cancer.

Highlights of This Issue

There is growing evidence suggesting that soy isoflavones play a protective role in the development of cancer. However, few epidemiological studies have investigated the association between soy isoflavone intake and bladder cancer. This prospective study in Japan detected a decreased risk of bladder cancer among men who had higher intakes of total soy and isoflavones, suggesting a protective effect of soy isoflavone intake against bladder cancer in men. This finding by Wada and colleagues on the potential benefit of consuming soy foods against bladder cancer is promising and warrants further studies.Americans living in rural communities face many challenges when it comes to receiving adequate cancer care. This has resulted in a growing disparity in mortality and incidence for certain cancers in rural areas when compared to their urban counterparts. In order to understand and improve cancer control in rural communities, the NCI conducted an assessment of the current state of research through a progressive series of portfolio analyses, meetings, and funding opportunity announcements. In this commentary, Kennedy and colleagues provide an overview of the NCI's vision for rural cancer control, and detail recommendations stemming from a recently held meeting to advance rural cancer control research. This commentary also serves as an introduction to the CEBP Focus on Rural Cancer Control, which contains three additional commentaries and six research articles.Human papillomavirus self-sampling is a promising method to improve cervical cancer screening coverage, but not all routine screening non-attenders accept self-sampling. Harder and colleagues investigated determinants of participating in self-sampling among 21,314 non-attenders in a Danish routine screening program who were invited to order a self-sampling test. Information on socio-demographic, health-related, and lifestyle characteristics were obtained from registries and questionnaires. Basic education, low income, non-Western origin, and being unmarried were associated with lower self-sampling participation. Women with prior schizophrenia and long-term screening non-attenders were less likely to participate. The study highlights that although self-sampling can increase cervical cancer screening coverage, certain population groups may remain unscreened.The use of alerts and reminders in the electronic health record has led to increased screening for a variety of conditions. However, implementation of screening recommendations for chronic hepatitis B among foreign-born persons at risk has been suboptimal. Chak and colleagues randomized patients at risk for chronic hepatitis B to receive an electronic medical alert reminding primary care physicians to screen for the virus during clinic visits. The study shows that electronic alerts increase screening for chronic hepatitis B—a condition known to cause liver cancer in affected patients. In the age of digital medicine, the study has broad implications for mass screening of patients at risk for this chronic viral infection.

Strong association between cervical and breast cancer screening behaviour among Danish women; A register-based cohort study.

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.
