Randomized experimental population-based study to evaluate the acceptance and completion of and preferences for cervical cancer screening

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.

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

OBJECTIVE

This study aims to evaluate the feasibility and applicability of an online cervical cancer screening program using a website as the public platform and self-collected HPV testing as the primary screening method.

METHODS

A website (mcareu.com) was developed to facilitate the online cervical cancer screening program by Peking University Shenzhen Hospital (PUSH). Women in Shenzhen could register for participation on the website by providing essential demographic data. Sampling kits and specimens were delivered through regular logistics. Eligible women collected vaginal samples by themselves using the provided kits and in referring of the graphic guidance. The specimens were tested for HPV at PUSH or a reference lab, and the results were accessible on the website through participants' personal accounts. Participants who tested positive for high-risk HPV were scheduled for colposcopy and biopsies. The demographic and social background data of the eligible participants were analyzed to evaluate the feasibility and applicability of the online screening approach.

RESULTS

A total of 1712 applicants registered for participation, with 99.9% (1710/1712) completing registration with full data. The analysis included 1560 applicants aged 30-59, with an average age of 41.1 (± 7.6) years. Among them, 83.3% (1299/1560) provided self-collected samples for testing. Age-group analysis revealed an overall sample provision rate (SPR) exceeded 80% in all age groups. A significant difference in SPR was observed only between the 30-34 and 45-49 age groups (p < 0.05), while no significant differences were found among other age groups. 99.7% of the samples were tested qualified, and there was no significant difference in sampling failure rate among age groups. Analysis of demographic and social elements showed no significant impact on the rates of sample provision among groups in most of the social elements but the medical insurance and the monthly family-incomes.

CONCLUSION

The findings demonstrate that online cervical cancer screening is reliable for self-registration, self-sampling, and self-ordering for specimen transportation. It is suitable for women of all ages needing to be screened, irrespective of social elements, and effectively facilitates screening for women with limited access to medical resources. Therefore, online screening holds promise as an effective approach to increase screening coverage.

Sexual orientation and gender identity inequities in cervical cancer screening by race and ethnicity

BACKGROUND

In the United States, inequities in preventive health behaviors such as cervical cancer screening have been documented. Sexual orientation, gender identity, and race/ethnicity all individually contribute to such disparities. However, little work has investigated their joint impact on screening behavior.

METHODS

Using sampling weighted data from the 2016 and 2018 Behavioral Risk Factor Surveillance System, we assessed differences in two metrics via chi-square statistics: 1) lifetime uptake, and 2) up-to-date cervical cancer screening by sexual orientation and gender identity, within and across racial/ethnic classifications.

RESULTS

Within all races, individuals who identify as members of sexual and gender minority (SGM) communities reported higher rates of never being screened (except for Black transgender men) than straight or cisgender individuals (p < 0.0001). [*START* Across all races, the Asian/Pacific Islander transgender population (32.4%; weighted n (w.n.) = 1,313) had the lowest proportion of lifetime screening, followed by the Asian/Pacific Islander gay/lesbian (53.0%, w.n. = 21,771), Hispanic transgender (58.7%; w.n. = 24,780), Asian/Pacific Islander bisexual (61.8%, w.n. = 54,524), and Hispanic gay/lesbian (69.6%, w.n. = 125,781) populations. *END*] Straight or cisgender Non-Hispanic White (w.n. = 40,664,476) individuals had the highest proportion of lifetime screening (97.7% and 97.5%, respectively). However, among individuals who had been screened at least once in their lifetime, identifying as SGM was not associated with a decreased proportion of up-to-date screening within or between races.

CONCLUSIONS

Due to small sample sizes, especially among Asian/Pacific Islander and Hispanic populations, confidence intervals were wide. Heterogeneity in screening participation by SGM status within and across racial/ethnic groups were observed.

IMPACT

These screening disparities reveal the need to disaggregate data to account for intersecting identities and for studies with larger sample sizes to increase estimate reliability.

Perceptions and implications for cervical screening and self-collection: A qualitative exploration of never and under-screened Queensland women

BACKGROUND

Over 70% of cervical cancers are detected in women not currently screening. Queensland Health wanted to better understand the drivers of screening to inform our planning and capitalise on self-collection as an option to reach under-screened women. In 2020 Queensland Health commissioned qualitative research to explore barriers and enablers to cervical screening with never-screened and under-screened women in Queensland (with under-screeners defined as having last screened more than 4 years ago and being more than 2 years overdue). Additionally, the research explored the acceptability of self-collection amongst this cohort.

METHODS

A mixed methods qualitative approach of online focus groups and in-depth interviews was employed. Online focus groups were conducted with under-screeners. In-depth telephone interviews were conducted with never-screeners due to the anticipated personal nature of their reasons for not screening.

RESULTS

A total of 51 Queensland women aged 30 to 50 years participated in the research.

CONCLUSIONS

Queensland women cited several negative experiences and aspects of the current program, as well as barriers in their social and personal lives that limited screening intention and behaviour. Barriers and enablers to cervical screening identified in this research have been classified into four categories: structural, knowledge and attitudinal, social, and personal. The research identified more factors associated with nonparticipation than participation. However, the research did uncover a range of potential enablers to encourage screening, some of which related to the program design. SO WHAT?: The concept of self-collection was broadly well accepted by research participants, particularly by never-screeners. Recommendations resulting from this research include communications, systems, and eligibility changes, particularly regarding the availability and benefits of self-collection.

Widening the offer of human papillomavirus self-sampling to all women eligible for cervical screening: Make haste slowly

Self-collection of samples for human papillomavirus (HPV) testing has the potential to increase the uptake of cervical screening among underscreened women and will likely form a crucial part of the WHO's strategy to eliminate cervical cancer by 2030. In high-income countries with long-standing, organised cervical screening programmes, self-collection is increasingly becoming available as a routine offer for women regardless of their screening histories, including under- and well-screened women. For these contexts, a validated microsimulation model determined that adding self-collection to clinician collection is likely to be cost-effective on the condition that it meets specific thresholds relating to (1) uptake and (2) sensitivity for the detection of high-grade cervical intraepithelial neoplasia (CIN2+). We used these thresholds to review the 'early-adopter' programme-level evidence with a mind to determine how well and how consistently they were being met. The available evidence suggested some risk to overall programme performance in the situation where low uptake among underscreened women was accompanied by a high rate of substituting clinician sampling with self-collection among well-screened women. Risk was further compounded in a situation where the slightly reduced sensitivity of self-sampling vs clinician sampling for the detection of CIN2+ was accompanied with lack of adherence to a follow-up triage test that required a clinician sample. To support real-world programmes on their pathways toward implementation and to avoid HPV self-collection being introduced as a screening measure in good faith but with counterproductive consequences, we conclude by identifying a range of mitigations and areas worthy of research prioritisation.

"So, if she wasn't aware of it, then how would everybody else out there be aware of it?"-Key Stakeholder Perspectives on the Initial Implementation of Self-Collection in Australia's Cervical Screening Program: A Qualitative Study

BACKGROUND

In December 2017, the Australian National Cervical Screening Program transitioned from 2-yearly cytology-based to 5-yearly human papillomavirus (HPV)-based cervical screening, including a vaginal self-collection option. Until July 2022, this option was restricted to under- or never-screened people aged 30 years and older who refused a speculum exam. We investigated the perspectives and experiences of stakeholders involved in, or affected by, the initial implementation of the restricted self-collection pathway.

METHODS

Semi-structured interviews were conducted with 49 stakeholders as part of the STakeholder Opinions of Renewal Implementation and Experiences Study. All interviews were audio recorded and transcribed. Data were thematically analysed and coded to the Conceptual Framework for Implementation Outcomes.

RESULTS

Stakeholders viewed the introduction of self-collection as an exciting opportunity to provide under-screened people with an alternative to a speculum examination. Adoption in clinical practice, however, was impacted by a lack of clear communication and promotion to providers, and the limited number of laboratories accredited to process self-collected samples. Primary care providers tasked with communicating and offering self-collection described confusion about the availability, participant eligibility, pathology processes, and clinical management processes for self-collection. Regulatory delay in developing an agreed protocol to approve laboratory processing of self-collected swabs, and consequently initially having one laboratory nationally accredited to process samples, led to missed opportunities and misinformation regarding the pathway's availability.

CONCLUSIONS

Whilst the introduction of self-collection was welcomed, clear communication from Government regarding setbacks in implementation and how to overcome these in practice were needed. As Australia moves to a policy of providing everyone eligible for screening the choice of self-collection, wider promotion to providers and eligible people, clarity around pathology processes and the scaling up of test availability, as well as timely education and communication of clinical management practice guidelines, are needed to ensure smoother program delivery in the future. Other countries implementing self-collection policies can learn from the implementation challenges faced by Australia.

Qualitative assessment of attitudes toward cervical cancer (CC) screening and HPV self-sampling among African American (AA) and Sub Saharan African Immigrant (SAI) women

OBJECTIVES

Despite the availability of preventive methods for cervical cancer (CC), uptake has been low among African American and Sub-Saharan Immigrant (AA/SAI) women. The purpose of this study was to understand AA/SAI women's values and beliefs of CC screening and explore willingness, acceptability, and concerns related to the HPV self-sampling method for CC.

DESIGN

Thirty AA/SAI women participated in one of six focus groups, each lasted 60-90 min, and were held over Zoom video conferencing. The sessions were audio-recorded, transcribed verbatim, and checked for accuracy by research staff prior to data analysis. Transcripts were content analyzed by two qualitatively trained research staff. NVivo software was used for data management and analysis.

RESULTS

The average age of participants was 33.67 ± 9.03, more than half were not married (53.3%), and less than half reported having health insurance coverage (46.7%). Participants included 16 AA and 14 SAI. Three main themes emerged from data analysis. (1) Beliefs and values related to CC Screening, (2) perceived barriers to attending CC screening, (3) recommendations to motivate regular CC screening. In addition, three factors emerged in the discussion on the HPV self-sampling method: confidence in ability to self-sample for CC, willingness to use HPV self-sampling kit, and result delivery.

CONCLUSIONS

This study identified a variety of reasons for the disproportionately low utilization of CC prevention services among AA/SAI women. Multidimensional approaches including educational and community engagement programs for this population could improve CC screening uptake and adoption of HPV self-sampling among AA/SAI women.

Self-sampling for cervical screening offered at the point of invitation: A cross-sectional study of preferences in England

OBJECTIVES

This study assessed preferences for human papillomavirus (HPV) self-sampling if offered as an alternative to clinician-based screening at the point of invitation for cervical screening.

SETTING AND METHODS

An online questionnaire was completed by screening-eligible women living in England (n = 3672). Logistic regressions explored associations between demographic characteristics and screening preferences, stratified by previous screening attendance. Reasons for preferences were also assessed.

RESULTS

Half of participants (51.4%) intended to choose self-sampling, 36.5% preferred clinician screening, 10.5% were unsure, and <2% preferred no screening. More irregular and never attenders chose self-sampling, compared with regular attenders (71.1% and 70.1% vs. 41.0% respectively). Among regular attenders, self-sampling was preferred more frequently by the highest occupational grade, older and lesbian, gay and bisexual women, and those with experience of blood self-tests. In the irregular attender group, older women and those with experience of blood self-tests were more likely to choose self-sampling. In 'never attenders', self-sampling was less popular in ethnic minority groups.

CONCLUSIONS

If offered a choice of screening, around half of women in England may choose self-sampling, but a substantial proportion would still opt for clinician screening. Screening providers will need to manage a high take-up of self-sampling if many regular attenders switch to self-sampling.

What do South Asian immigrant women know about HPV, cervical cancer and its early detection: A cross-sectional Australian study

•

Low HPV and cervical cancer knowledge levels among South Asian immigrant women.

•

One third participants aware of the renewed cervical screening program changes.

•

Screening uptake significantly associated with HPV and cervical cancer awareness.

•

GP discussion on the topic found to have important role in increasing knowledge.

Cervical cancer commonly caused by Human Papillomavirus (HPV) imposes a significant burden in Asia. This study examined the awareness and knowledge of HPV, cervical cancer, and its early detection methods among South Asian immigrant women in Australia to determine factors associated with knowledge deficits. A cross-sectional internet-based survey was completed by a convenience sample of women (n=148), with South-Asian background, residing in Queensland during May-October 2019. Main outcome variables were awareness of HPV, cervical cancer, cervical screening test (Pap test and HPV test) and HPV test self-sampling availability (Yes/No). HPV and cervical cancer knowledge were assessed via 16-item and 20 item aggregated scales respectively, (higher scores indicating better knowledge). Five individual items queried knowledge of the Pap and HPV test, and one item actual cervical screening uptake. One-way ANOVA was used to study differences in HPV and cervical cancer knowledge among sociodemographic groups. Of 148 participating women, 55% (n=86) had heard of HPV, 77% (n=114) of cervical cancer and 81.8% (n=121) of Pap tests. Only one third of participants (n=49) were aware that now an HPV test is used for cervical screening and 10% (n=15) of its self-sampling availability, whereas 55.4% (n=82) reported participation in screening previously. The mean HPV knowledge score was 5.3 (S.D: 5.7) and mean cervical cancer knowledge score 9.8 (S.D: 6.5) with zero being the most common score on both scales. Higher knowledge scores were significantly associated with higher educational level, English language proficiency, discussion with a GP on the topic and previous participation in screening. The majority of participants lacked detailed knowledge about the available screening tests. This study identified key target groups for future interventions.

Knowledge, attitude and practice of female university students regarding human papillomavirus and self-sampling in KwaZulu-Natal, South Africa: a cross-sectional survey

Background

Human papillomavirus (HPV) infection remains a major cause of cervical cancer. Screening practice in South Africa has remained persistently low, with the invasiveness of pelvic examination as a major barrier to screening. This occasions the need to assess women’s knowledge, attitude, and practice regarding HPV testing and self-sampling.

Method

This is a cross-sectional quantitative study which enrolled 386 female students between the ages of 18 and 65 years at the University of KwaZulu-Natal, South Africa. Data was collected through a self-administered structured questionnaire, from February to March 2020. Data on participants’ socio-demographic characteristics, knowledge, attitudes and practices regarding HPV, HPV testing and self-sampling were obtained.

Results

Out of the 386 respondents, 30.6% were unaware that HPV can be transmitted through unprotected sex, only 25.1% knew about the availability of HPV vaccines in South Africa, 16.1% knew that the vaccines are accessible for free, while 79.0% were oblivious to the asymptomatic nature of HPV infection. Furthermore, a vast majority (95.8%) had never heard about self-sampling while only 1.0% had undergone HPV testing prior to this study. Although 52.9% knew that HPV testing could prevent cervical cancer, it did not positively impact screening practice. However, 57.7% of participants were willing to undergo future screening if allowed to self-sample.

Conclusion

Self-sampling is a more acceptable means of sample collection compared to pelvic examination. Therefore, encouraging self-sampling and providing self-sampling kits will aid increased screening participation and address certain barriers associated with HPV testing. Awareness and educational campaigns about HPV and its causative relationship with cervical cancer will occasion better attitude towards screening participation.

Aboriginal and Torres Strait Islander women's views of cervical screening by self-collection: a qualitative study

OBJECTIVE

This study aimed to describe Aboriginal and Torres Strait Islander women's views of self-collection introduced in the renewed National Cervical Screening Program.

METHODS

A total of 79 Aboriginal and/or Torres Strait Islander women (50 screened in previous five years, 29 under-screened) from five clinics across three Australian states/territories participated. Topics discussed were perceptions of self-collection, the instruction card and suggestions for implementing self-collection. We employed yarning (a qualitative method), which established relationships and trust between participants and researchers to facilitate culturally safe conversations. Transcripts were analysed thematically.

RESULTS

Most women were unaware of self-collection before the yarn but found it to be an acceptable way to participate in cervical screening. Women perceived self-collection would be convenient, provide a sense of control over the screening experience, and maintain privacy and comfort. The instructions were perceived to be simple and easy to follow. Women had concerns about collecting the sample correctly and the accuracy of the sample (compared to clinician-collected samples).

CONCLUSIONS

Self-collection is acceptable to Aboriginal and Torres Strait Islander women. Implications for public health: Given the inequitable burden of cervical cancer experienced by Aboriginal and Torres Strait Islander women, self-collection is likely to significantly improve participation and ultimately improve cervical cancer outcomes.

Switching clinic-based cervical cancer screening programs to human papillomavirus self-sampling: A cost-effectiveness analysis of vaccinated and unvaccinated Norwegian women

Several countries have implemented primary human papillomavirus (HPV) testing for cervical cancer screening. HPV testing enables home-based, self-collected sampling (self-sampling), which provides similar diagnostic accuracy as clinician-collected samples. We evaluated the impact and cost-effectiveness of switching an entire organized screening program to primary HPV self-sampling among cohorts of HPV vaccinated and unvaccinated Norwegian women. We conducted a model-based analysis to project long-term health and economic outcomes for birth cohorts with different HPV vaccine exposure, that is, preadolescent vaccination (2000- and 2008-cohorts), multiage cohort vaccination (1991-cohort) or no vaccination (1985-cohort). We compared the cost-effectiveness of switching current guidelines with clinician-collected HPV testing to HPV self-sampling for these cohorts and considered an additional 44 strategies involving either HPV self-sampling or clinician-collected HPV testing at different screening frequencies for the 2000- and 2008-cohorts. Given Norwegian benchmarks for cost-effectiveness, we considered a strategy with an additional cost per quality-adjusted life-year below $55 000 as cost-effective. HPV self-sampling strategies considerably reduced screening costs (ie, by 24%-40% across cohorts and alternative strategies) and were more cost-effective than clinician-collected HPV testing. For cohorts offered preadolescent vaccination, cost-effective strategies involved HPV self-sampling three times (2000-cohort) and twice (2008-cohort) per lifetime. In conclusion, we found that switching from clinician-collected to self-collected HPV testing in cervical screening may be cost-effective among both highly vaccinated and unvaccinated cohorts of Norwegian women.

The experience of under-screened and never-screened participants using clinician-supported self-collection cervical screening within the Australian National Cervical Screening Program

Background:

Australia has had significant successes in the prevention of cervical cancer. However, there is considerable scope for improving screening participation. In December 2017, Australia shifted from cytology to a human papillomavirus–based screening program as part of the renewed National Cervical Screening Program. This provided the opportunity to introduce a clinician-supported self-collection cervical screening pathway, which allows screening participants aged 30 years or more and who are under-screened or never-screened to screen via a self-collected human papillomavirus test.

Objective:

This study aimed to explore screening participant experiences of a clinician-supported self-collection cervical screening pathway.

Methods:

Interviews (n = 45) were conducted with participants who had used the clinician-supported self-collection cervical screening pathway in the Australian National Cervical Screening Program between December 2017 and April 2019. Interviews were analyzed using template analysis.

Results:

Under-screened and never-screened participants reported a variety of interrelated barriers to cervical screening due to the nature of the test. For these participants, self-collection was a preferable way to perform screening as it overcame various barriers, was easy to use and promoted a sense of empowerment. Participants reported that the role of their practitioner was influential in their decision to undertake cervical screening, and that the support and information provided was a key factor in their experiences of the self-collection pathway.

Conclusion:

Findings support the use of a clinician-supported model of care, as an alternative screening modality in Australia’s National Cervical Screening Program. As more countries consider the move from a cytology to human papillomavirus–based cervical screening program, this model may assist in greater engagement of under-screened participants.

Comparison of cervical cancer screening by self-sampling papillomavirus test versus pap-smear in underprivileged women in France

BACKGROUND

The purpose of this study was to compare cervical cancer screening by pap smear (PS) versus preliminary HPV testing based on self-collected samples (SC-HPV).

METHODS

Interventional study among underprivileged women from 25 to 65 years old in four French cities. The control group (CG) was referred for a PS. The experimental group (EG) conducted a SC-HPV test followed by a PS in case of positivity. Differences on screening completion and cytological abnormalities were analysed by logistic and Cox regression.

RESULTS

383 women were assigned to the EG and 304 to the CG. The screening completion proportion was 39.5% in the CG compared to 71.3% in the EG (HR = 2.48 (CI 95% [1.99-3.08]; p < 0.001). The proportion of cytological abnormalities was 2.0% in the CG and 2.3% in the EG (OR = 1.20 (CI 95% [0.42-3.40]; p = 0.7). The proportion of participants lost to follow-up was 60.5% in the CG and 63.2% in the EG HPV positive (p = 0.18).

CONCLUSION

Providing an SC-HPV-test increased the participation of underprivileged women in CCS. Nevertheless, the significant number of lost to follow-up in both groups can undermine the initial benefits of the strategy for HPV positive women. Registration: Clinicaltrials.gov: NCT03118258.

Barriers and facilitators to participation in breast, bowel and cervical cancer screening in rural Victoria: A qualitative study

Issue addressed

Population cancer screening rates are around 50% for the general population and even lower in rural areas. This study aimed to explore knowledge, attitudes, behaviours, motivators and barriers to breast, bowel and cervical screening participation in under‐screened men and women.

Methods

We used a qualitative research design. Focus groups were segmented by age, sex and screening participation. Participants were under‐screened in at least one of the cancer screening programs, with separate groups for each of the programs. The discussion guides were designed around the Health Belief Model and group discussions were coded using a thematic content analysis approach.

Results

Fourteen focus groups were held with 80 participants. Key themes were that the concept of cancer screening was not well understood, a low priority for preventive health behaviours, issues relating to local general practitioners (GP) and screening was unpleasant, embarrassing and/or inconvenient. A key determinant of participation in cancer screening was exposure to prompts to action, and it was evident that participants often required multiple prompts before they took action.

Conclusions

Opportunities that develop attitudes to health that place disease prevention as a high priority; improve understanding of the benefit of screening in terms of early detection and treatment; improve GP availability and the patient‐practitioner relationship; and the development of messages for each of the screening programs should be further explored as factors that may influence rural population screening rates.

So what?

Addressing health attitudes, beliefs, knowledge, health practitioner and test‐related barriers and improving messaging may increase cancer screening participation in under‐screened rural populations.

Could HPV Testing on Self-collected Samples Be Routinely Used in an Organized Cervical Screening Program? A Modeled Analysis

BACKGROUND

Cervical screening on self-collected samples has mainly been considered for targeted use in underscreened women. Updated evidence supports equivalent sensitivity of PCR-based human papillomavirus (HPV) testing on self-collected and clinician-collected samples.

METHODS

Using a well-established model, we compared the lifetime impact on cancer diagnoses and deaths resulting from cervical screening using self-collected samples only, with and without the existing restriction in Australia to women aged 30+ years and ≥2 years overdue, compared with the mainstream program of 5-yearly HPV screening on clinician-collected samples starting at 25 years of age. We conservatively assumed sensitivity of HPV testing on self-collected relative to clinician-collected samples was 0.98. Outcomes were estimated either in the context of HPV vaccination ("routinely vaccinated cohorts;" uptake as in Australia) or in the absence of HPV vaccination ("unvaccinated cohorts").

RESULTS

In unvaccinated cohorts, the health benefits of increased participation from self-collection outweighed the worst case (2%) loss of relative test sensitivity even if only 15% of women, who would not otherwise attend, used it ("additional uptake"). In routinely vaccinated cohorts, population-wide self-collection could be marginally (0.2%-1.0%) less effective at 15% additional uptake but 6.2% to 12.4% more effective at 50% additional uptake. Most (56.6%-65.0%) of the loss in effectiveness in the restricted self-collection pathway in Australia results from the requirement to be 2 or more years overdue.

CONCLUSIONS

Even under pessimistic assumptions, any potential loss in test sensitivity from self-collection is likely outweighed by improved program effectiveness resulting from feasible levels of increased uptake.

IMPACT

Consideration could be given to offering self-collection more widely, potentially as an equal choice for women.See related commentary by Lim, p. 245.

The Acceptability and Preference of Vaginal Self-sampling for Human Papillomavirus (HPV) Testing among a Multi-ethnic Asian Female Population

Vaginal self-sampling for human papillomavirus (HPV) testing can potentially increase cervical screening coverage. This study aimed to investigate the acceptability of vaginal self-sampling for HPV testing and factors that might influence a woman's preference for this as a cervical screening method. This was a cross-sectional study that recruited 725 women from the urban and suburban areas of Selangor, Malaysia. All study participants were instructed to self-collect vaginal sample using a dry flocked swab before responding to a detailed questionnaire documenting their experience and preference for self-sampling. Most of the study participants (>80%) perceived vaginal self-sampling as easy, convenient, not embarrassing, comfortable, and were confident in performing the test. This suggests high acceptability toward vaginal self-sampling for HPV testing. Of the 725 women, 83% preferred self-sampling HPV testing over healthcare personnel sampling HPV testing and Pap test. Women with higher household income and full-time employment status were more likely to prefer self-sampling. Those who had not undergone Pap test also expressed preference for self-sampling HPV testing. Convenience and women's confidence in performing a vaginal self-sampling for HPV testing were the independent key factors that influenced the preference for self-sampling method. Vaginal self-sampling for HPV testing is highly acceptable among Malaysian women. It is the preferred choice as a primary cervical screening method and serves as an alternative to healthcare-acquired sample for Pap test. PREVENTION RELEVANCE: Organized cervical cancer screening remains unachievable in many countries. Self-sampling HPV testing is an evidence-based method that can remove barriers to cervical screening. This is particularly important for developing countries in order to achieve the WHO global strategy to accelerate cervical cancer elimination.

Women's attitudes and understanding of cervical cancer and the new National Cervical Screening Program

ISSUES ADDRESSED

The new National Cervical Screening Program (NCSP) has recently been implemented. Little research is available on women's attitudes towards the program. This study aims to quantitatively assess Australian women's understanding and attitudes towards the new guidelines and their barriers to screening.

METHOD

Authors designed a cross-sectional survey which was piloted and distributed as a waiting room survey to eligible women who attended a private general practice in North Queensland.

RESULTS

Of the respondents, 53.8% had accurate knowledge of the new NCSP. Most participants (75.8%) believed they were not provided sufficient information about the NCSP and 60.2% wished to receive this information from their general practitioner. The screening test itself remains an issue, with embarrassment and discomfort listed as the most common barriers to screening.

CONCLUSION

Many women do not have accurate knowledge of the new NCSP. Further health promotion in this area is warranted, where the general practitioner may play a key role. SO WHAT?: While the new NCSP will lead to further reduction in cervical cancer mortality, it appears from the data that women did not fully understand cervical cancer and its screening. This suggests the need for further health education to women about updated screening guidelines.

Reasons for Not Attending Cervical Cancer Screening and Associated Factors in Rural Ethiopia

Social, economic, and cultural factors have been associated with the level of participation in cervical cancer screening programs. This study identified factors associated with nonparticipation in cervical cancer screening, as well as reasons for not attending, in the context of a population-based, cluster-randomized trial in Ethiopia. A total of 2,356 women aged 30 to 49 years in 22 clusters were invited to receive one of two screening approaches, namely human papillomavirus (HPV) self-sampling or visual inspection with acetic acid (VIA). Participants and nonparticipants were analyzed according to their sociodemographic and economic characteristics. Reasons were determined for the refusal of women to participate in either screening method. More women in the VIA arm compared to the HPV arm declined participation in the screening [adjusted OR (AOR) 3.5; 95% confidence interval (CI), 2.6-4.8]. Women who declined attending screening were more often living in rural areas (AOR = 2.0; 95% CI, 1.1-3.5) and were engaged in informal occupations (AOR = 1.6; 95% CI, 1.1-2.4). The majority of nonattendants perceived themselves to be at no risk of cervical cancer (83.1%). The main reasons given for not attending screening for both screening approaches were lack of time to attend screening, self-assertion of being healthy, and fear of screening. We found that perceived time constraints and the perception of being at no risk of getting the disease were the most important barriers to screening. Living in rural settings and informal occupation were also associated with lower participation. Offering a swift and convenient screening service could increase the participation of women in cervical cancer screening at the community level.

Cost-effectiveness studies of HPV self-sampling: A systematic review

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

[MDM and proportionate universalism applied to cervical cancer prevention]

For over 30 years, Médecins du Monde (MDM) has been working with people living in vulnerable conditions in order to promote and facilitate their access to fundamental human rights and healthcare. Women encountered within MDM programs have many risk factors for developing precancerous and cancerous lesions of the cervix. They may not seek or have little access to health services and preventive health measures.These findings prompted MDM to adopt a 'proportionate universalism' approach in order to improve access to prevention for people living in vulnerable conditions, by reaching out to the population and offering preventative health consultations. In order to address health inequalities, this approach combines health mediation, use of visuals (binder, patient leaflet), professional interpretation services, as well as preventative health consultations run by a team aware of counselling approaches and techniques. MDM diversifies screening options by inviting women to perform a self-collected vaginal swab for high risk HPV testing.This multi-level intervention aims to create favorable conditions for public participation and empowerment by promoting specifically tailored tools and a "proportionate universalism" approach.

Self-collected Pap smears may provide an acceptable and effective method of cervical cancer screening

BACKGROUND AND AIMS

The role of the Papanicolou (Pap) smear in the early detection and prevention of cervical cancer is well established. However, many women fail to undertake the test because of embarrassment or other reasons. To address this problem, we evaluated the feasibility of implementing self-sampling of cervical cytology as an alternative to clinician-collected Pap smears and compared it with the gold standard of colposcopy in terms of specificity.

MATERIALS AND METHODS

A prospective preliminary study of 40 women recruited from the colposcopy clinic of a tertiary referral hospital was undertaken. Participants were instructed in the technique of self-sampling and asked to collect their own Pap smears. Colposcopic examinations were performed and biopsies taken, if indicated. Clinician-collected Pap smears were performed 4 weeks later. Pairwise agreement was calculated between the outcomes of self-collected, colposcopic, and clinician-collected samples using the weighted κ statistic.

RESULTS

Self-collected Pap smear had a high level of acceptability among the women, all of whom were able to collect adequate tissue. The agreement of self-collected Pap smears with colposcopic assessment was no worse than that of clinician-collected Pap smears (Cohen's κ statistic 0.54 [95% CI, 0.27-0.82]; cf 0.49 [0.2-0.78], respectively). The specificity of self-collected Pap smears was almost identical to that of clinician-collected samples (specificity: 86% vs 81%, respectively). Direct comparison between patient and clinician collected Pap smears showed fair agreement (κ statistic 0.38 [0.07-0.68]). There were no adverse events in either group.

CONCLUSIONS

Self-collection of Pap smears is an effective and acceptable alternative to clinician-collected samples and may provide a strategy for improving compliance with cervical testing programs.

Completing the cervical screening pathway: Factors that facilitate the increase of self-collection uptake among under-screened and never-screened women, an Australian pilot study

Objectives

To examine factors that enhance under-screened and never-screened women's completion of the self-collection alternative pathway of the Renewed National Cervical Screening Program (ncsp) in Victoria, Australia.

Background

With the Australian ncsp changing, starting on 1 December 2017, the Medical Services Advisory Committee (msac) recommended implementing human papillomavirus (hpv) testing using a self-collected sample for under-screened and never-screened populations. In response, a multi-agency group implemented an hpv self-collection pilot project to trial self-collection screening pathways for eligible women.

Methods

Quantitative data were collected on participation rates and compliance rates with follow-up procedures across three primary health care settings. Forty women who self-collected were interviewed in a semi-structured format, and seven agency staff completed in-depth interviews. Qualitative data were used to identify and understand clinical and personal enablers that assisted women to complete self-collection cervical screening pathways successfully.

Results

Eighty-five per cent (10 women) of participants who tested positive for hpv successfully received their results and completed follow-up procedures as required. Two remaining participants also received hpv-positive results. However, agencies were unable to engage them in follow-up services and procedures. The overall participation rate in screening (self-collection or Pap test) was 85.7% (84 women), with 79 women self-collecting. Qualitative data indicated that clear explanations on self-collection, development of trusting, empathetic relationships with health professionals, and recognition of participants' past experiences were critical to the successful completion of the self-collection pathway. When asked about possible inhibitors to screening and to following up on results and appointments, women cited poor physical and mental health, as well as financial and other structural barriers.

Conclusion

A well-implemented process, led by trusted, knowledgeable, and engaged health care professionals who can provide appropriate support and information, can assist under-screened and never-screened women to complete the hpv self-collection pathway successfully.

Self-administered versus provider-directed sampling in the Anishinaabek Cervical Cancer Screening Study (ACCSS): a qualitative investigation with Canadian First Nations women

BACKGROUND

While (Pap)anicolaou screening has helped to decrease cervical cancer incidence in Canada, First Nations women continue to have a higher burden and mortality relative to mainstream populations. Many First Nations women may feel uncomfortable with the invasiveness of this test, contributing to this statistic. Implemented from 2009 to 2015 in 10 Northwest Ontario First Nations communities, the Anishinaabek Cervical Cancer Screening Study (ACCSS) uniquely addressed this Indigenous health inequity through a mixed methods approach.

OBJECTIVE

Our goal was to offer an alternative test which the women could do themselves: human papillomavirus (HPV) testing based on self-sampling. We investigated whether First Nations women preferred HPV self-sampling over healthcare provider (HCP)-administered Pap screening.

METHODS

Participatory action researchinformed by the ethical space concept has guided all stages of the ACCSS. We conducted qualitative interviews with 16 HCPs and 8 focus group discussions with 69 female community members followed by a cluster-randomised controlled trial (RCT). Here, we draw on the qualitative field data and an end-of-study community update gathering to disseminate and contextualise research findings. Informant data were evaluated using thematic analysis.

RESULTS

We discuss factors influencing participants' strong preference for HPV self-sampling over physician-conducted Pap screening. Key arguments included enhanced accessibility and more personal control, less physical and emotional discomfort and fewer concerns regarding privacy of test results. For future implementation of HPV self-sampling, study participants emphasised the need for more culturally sensitive education addressed to community members of all genders, starting at school, clarifying that HPV causes cervical cancer. Further, HPV infection should be de-stigmatised by accentuating that it affects men and women alike.

CONCLUSION

Here we show that self-sampling in conjunction with community engagement and culturally sensitive education and could be a viable option for underscreened Canadian First Nations women. These informant data echo our previous RCT results.

Impact of HPV sample self-collection for underscreened women in the renewed Cervical Screening Program

OBJECTIVES

In 2017, the National Cervical Screening Program in Australia will transition to 5-yearly primary HPV screening for all women, irrespective of human papillomavirus (HPV) vaccination status. As an adjunct to the mainstream program, HPV testing on self-collected samples will be offered under practitioner supervision to all unscreened and underscreened women aged 30-74 years. We quantified how different screening decisions affect the future risk of cervical cancer.

DESIGN

Simulation of outcomes for 100 000 previously unscreened women, aged 30 years and eligible for self-collection, using a well-established model of HPV natural history and cervical screening.

MAIN OUTCOME MEASURES

Cumulative cancer diagnoses and deaths averted (compared with remaining unscreened) to age 84, number needed to treat for pre-cancer (NNT) to avert each cancer diagnosis.

RESULTS

One round of self-collected HPV screening at age 30 years would avert 908 cancer diagnoses and 364 cancer deaths in the cohort by age 84 (NNT, 5.8). Benefits would still be achieved were self-collected screening delayed to age 40 (922 fewer diagnoses; 426 fewer deaths; NNT, 3.7) or 50 (684 fewer diagnoses; 385 fewer deaths; NNT, 3.2). However, the benefits associated with joining the mainstream screening program would be substantially larger (2002, 1623 or 1091 fewer diagnoses and NNT of 4.9, 3.7 or 3.4 by joining at age 30, 40 or 50 years respectively). The relative benefits of joining the mainstream program were similar for cohorts who had been offered vaccination.

CONCLUSIONS

Offering HPV self-collection has the potential to considerably improve outcomes for unscreened and underscreened women. Nevertheless, these findings underscore the need for concerted strategies to encourage these women to join the mainstream HPV screening program.

Transformation of the genital epithelial tract occurs early in California sea lion development

An unusually high prevalence of metastatic urogenital carcinoma has been observed in free-ranging California sea lions stranded off the coast of California in the past two decades. No cases have been reported for sea lions in the relatively unpolluted Gulf of California. We investigated occurrence of genital epithelial transformation in 60 sea lions (n=57 pups and 3 adult females) from the Gulf of California and examined whether infection by a viral pathogen previously found to be associated with urogenital carcinoma accounted for such alterations. We also explored the contribution of MHC class II gene expression on transformation. Cellular alterations, such as squamous cell atypia (ASC), atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions were observed in 42% of the pups and in 67% of the adult females. Normal genital epithelium was more common in male than female pups. ASC was five times more likely to occur in older pups. Epithelial alterations were unrelated to infection by the potentially oncogenic otarine type I gammaherpesvirus (OtHV-1), but ASCUS was more common in pups with marked and severe inflammation. Expression of MHC class II DRB loci (Zaca DRB-D) by peripheral antigen-presenting leucocytes showed a slightly 'protective' effect for ASC. We propose that transformation of the California sea lion genital epithelium is relatively common in young animals, increases with age and is probably the result of infection by an unidentified pathogen. Expression of a specific MHC class II gene, suggestive of presentation of specific antigenic peptides to immune effectors, appears to lower the risk of transformation. Our study provides the first evidence that epithelial transformation of the California sea lion genital tract is relatively common, even from an early age, and raises questions regarding differences in sea lion cancer-detection and -repair success between geographical regions.

Women's experience with home-based self-sampling for human papillomavirus testing

Background

Increasing cervical screening coverage by reaching inadequately screened groups is essential for improving the effectiveness of cervical screening programs. Offering HPV self-sampling to women who are never or under-screened can improve screening participation, however participation varies widely between settings. Information on women’s experience with self-sampling and preferences for future self-sampling screening is essential for programs to optimize participation.

Methods

The survey was conducted as part of a larger trial (“iPap”) investigating the effect of HPV self-sampling on participation of never and under-screened women in Victoria, Australia. Questionnaires were mailed to a) most women who participated in the self-sampling to document their experience with and preference for self-sampling in future, and b) a sample of the women who did not participate asking reasons for non-participation and suggestions for enabling participation. Reasons for not having a previous Pap test were also explored.

Results

About half the women who collected a self sample for the iPap trial returned the subsequent questionnaire (746/1521). Common reasons for not having cervical screening were that having Pap test performed by a doctor was embarrassing (18 %), not having the time (14 %), or that a Pap test was painful and uncomfortable (11 %). Most (94 %) found the home-based self-sampling less embarrassing, less uncomfortable (90 %) and more convenient (98 %) compared with their last Pap test experience (if they had one); however, many were unsure about the test accuracy (57 %). Women who self-sampled thought the instructions were clear (98 %), it was easy to use the swab (95 %), and were generally confident that they did the test correctly (81 %). Most preferred to take the self-sample at home in the future (88 %) because it was simple and did not require a doctor’s appointment. Few women (126/1946, 7 %) who did not return a self-sample in the iPap trial returned the questionnaire. Their main reason for not screening was having had a hysterectomy.

Conclusions

Home-based self-sampling can overcome emotional and practical barriers to Pap test and increase participation in cervical screening despite some women’s concerns about test accuracy. Mailing to eligible women and assuring women about test accuracy could further optimize participation in screening.
