Perspectives of women participating in a cervical cancer screening campaign with community-based HPV self-sampling in rural western Kenya: a qualitative study

Barriers to cervical cancer screening in Africa: a systematic review

INTRODUCTION

Africa has one of the highest burdens of cervical cancer in the world. The unacceptably high incidence and mortality rates could be reduced through implementing a comprehensive approach to its prevention and control that includes screening, which however, is low in most low-and-middle-income countries. Hence, this systematic review aims at exploring factors that prevent women from utilising cervical cancer screening services in the region.

METHODS

A mixed method systematic review was conducted. A search was performed on PubMed (Medline), EMBASE, CINAHL (EBSCOHOST) and Scopus databases for articles published until May 2019 without time, language or study design limits. Two reviewers critically appraised the included studies independently using the standard quality assessment criteria for evaluating primary research papers. Results of the quantitative and mixed methods studies were transformed into qualitative data and synthesised using thematic analysis.

RESULTS

From a potential 2 365 studies, 24 from 11 countries met the eligibility criteria and were selected; eight qualitative, 13 quantitative, and three that used the mixed-method approach. The primary barriers were identified as poor access to screening services, lack of awareness and knowledge on cervical cancer and screening, and socio-cultural influences. Service providers perceived lack of skills, screening equipment and supplies, and staff shortages as the major barriers to the provision of screening services.

CONCLUSION

Barriers to cervical cancer screening in Africa are multifaceted and require a holistic approach that will address them concurrently at the health system, individual, interpersonal, community and structural levels. Political will complimented by stakeholder involvement is required in the development and implementation of strategies that will ensure acceptability, availability, accessibility, and affordability of screening to minimise barriers in accessing the service.

Evaluation of video-assisted HPV education in government-supported clinics in Western Kenya

Despite prevalent preventative methods of human papillomavirus (HPV), cervical cancer remains the foremost cause of cancer-related death among women of reproductive age in Western Kenya. HPV self-sampling is a preventative measure that can improve accessibility and availability to cervical cancer screening. Correct education about HPV is crucial to combating stigma and increasing HPV screening uptake. In this study, we evaluated the workflow impact of a video-assisted HPV education to promote self-sampling in clinical settings in Kisumu, Kenya. We conducted a descriptive workflow study nested in a two-part cluster-randomized control trial in six government-supported health clinics in Kisumu County. We observed the workflow of HPV screening video-assisted and standard health educations. and evaluated community and clinic health assistant facilitation (CCHA), duration, and feasibility of the intervention. Thirty HPV screening-eligible women who participated in the video intervention were recruited for three focus group discussions (FGDs). The FGDs aimed to better understand women's experience with the video screening, their impressions on the content, and feedback about intervention logistics. Across 33 observations, 16.5 women per day watched the educational video at intervention clinics, and 14 women per day heard standard Ministry of Health cervical cancer prevention education talks at control clinics. Sixty-three percent of women participated in HPV self-sampling in the intervention sites, compared to forty-six percent who screened after standard health talks at control sites. The workflow observations identified variable video projection and viewing space, access to power supply, and CCHA availability and ability to utilize the projector as major factors impacting education workflow. Women in FGDs appreciated the video modality, length of video, and education location. HPV video education is a suitable intervention, with further research recommended to determine the viability of sustainably implementing the intervention in a clinic environment. This research is fully funded by the Duke University Global Health Institute.

Co-creation of human papillomavirus self-sampling delivery strategies for cervical cancer screening in rural Zimbabwe: nominal group technique

Background

Human papillomavirus (HPV) self-sampling is recommended for cervical cancer screening, particularly among women who do not participate in or have access to current screening methods offered in Zimbabwe. Key stakeholder involvement is critical in co-creating acceptable delivery strategies for implementing HPV self-sampling to ensure demand and facilitate uptake by the target population. The main objective of this study was to engage key stakeholders in co-creating acceptable HPV self-sampling delivery strategies for cervical cancer screening in rural Zimbabwe.

Methods

We invited key stakeholders and employed a nominal group technique (NGT) for data collection. We employed the NGT to (1) identify barriers to access and utilisation of available cervical cancer screening services and (2) co-create delivery strategies for HPV self-sampling. The workshop included 8 participants (women n = 4, health workers n = 2 and policymakers n = 2). Quantitative data was gathered by ranking ideas and qualitative data were collected from participant group discussions and analysed thematically. The results of the ranking exercise were fed back to the participants for comments.

Results

The most significant barriers to accessing and utilising current cervical cancer screening services by women were: Inadequate information and education on cervical cancer, lack of resources and funding for cervical cancer programmes, long distances to nearest health facilities, and low perceived personal risk of cervical cancer. Key stakeholders recommended enhanced education and awareness, results notification, linkage to care, community-based self-sampling, and the choice of sampling devices as potential HPV self-sampling delivery strategies.

Conclusion

Our study demonstrated the utility of the NGT for reaching a consensus. Using the NGT, we established priority delivery strategies for HPV self-sampling cervical cancer screening. Adequate education and awareness, early results notification, choice of sampling device and community-based self-sampling were crucial to HPV self-sampling screening in rural Zimbabwe. The proposed delivery strategies can guide the development of guidelines for designing and implementing an HPV self-sampling intervention. We recommend a study to determine women's most preferred HPV self-sampling delivery strategies before implementing the intervention.

Factors Influencing the Experience of Breast and Cervical Cancer Screening Among Women in Low- and Middle-Income Countries: A Systematic Review

PURPOSE

The persistent high morbidity and mortality from breast and cervical cancer in low- and middle-income countries (LMICs) may be influenced by global disparities in the uptake of screening services. This review sought to synthesize existing evidence to determine factors that influence the experience of women relating to breast and cervical screening in LMICs.

METHODS

A qualitative systematic review of the literature identified through Global Health, Embase, PsycInfo, and MEDLINE. Eligible studies included those outlining primary qualitative research or mixed-method studies with reporting of qualitative findings, detailing women's experiences of involvement with programs for breast or cervical cancer screening. Framework synthesis was used to explore and organize findings from primary qualitative studies and the Critical Appraisal Skills Programme checklist used for quality assessment.

RESULTS

Database searches yielded 7,264 studies for title and abstract screening and 90 full-text articles for screening, with qualitative data from 17 studies and a total of 722 participants included in this review. Four stages influencing experiences of women were generated across both breast and cervical cancer screening approaches, with individual (eg, knowledge of cancer), social (eg, religion, cultural beliefs), and health system (eg, accessibility) factors identified that influence women's initial and subsequent engagement.

CONCLUSION

This study synthesizes existing evidence of factors that influence engagement with breast and cervical cancer screening in LMICs. Evidence-informed recommendations are proposed that may improve the experience of cancer screening in LMICs, with further research necessary to explore their operationalization and impact on cancer care delivery.

Mapping evidence on the acceptability of human papillomavirus self-sampling for cervical cancer screening among women in sub-Saharan Africa: a scoping review

OBJECTIVES

The objective of this scoping review was to map evidence on the acceptability of self-sampling for human papillomavirus testing (HPVSS) for cervical cancer screening among women in the sub-Saharan Africa region.

DESIGN

Scoping review.

METHODS

Using Arksey and O'Malley's framework, we searched Scopus, PubMed, Medline Ovid, Cochrane and Web of Science databases for evidence on the acceptability of HPVSS among women aged 25 years and older published between January 2011 and July 2021. We included studies that reported evidence on the acceptability of HPVSS for cervical cancer screening. Review articles and protocols were excluded. We also searched for evidence from grey literature sources such as dissertations/theses, conference proceedings, websites of international organisations such as WHO and relevant government reports. Two reviewers independently performed the extraction using a pre-designed Excel spreadsheet and emerging themes were narratively summarised.

RESULTS

The initial search retrieved 1018 articles. Of these, 19 articles were eligible and included in the review. The following themes emerged from the included articles: acceptability of HPVSS; lack of self-efficacy to perform HPVSS, complications when performing HPVSS, preferences for provider sampling or assistance; setting of HPVSS; HPVSS by vulnerable populations.

CONCLUSION

Evidence shows that HPVSS is highly acceptable for cervical cancer screening in sub-Saharan Africa. Further research exploring the acceptability of HPVSS among women residing in rural areas is required, as well as studies to determine women's preferences for HPVSS intervention including the preferred type of sampling devices. Knowledge on the acceptability and preferences for HPVSS is important in designing women-centred interventions that have the potential to increase screening coverage and participation in cervical cancer screening programmes.

Clinical and psychosocial constructs for breast, cervical, and colorectal cancer screening participation: A systematic review

Research has identified a wide range of psychosocial factors associated to choosing to engage in ongoing cancer screenings. Nevertheless, a systematic review of the theoretical frameworks and constructs underpinning studies on breast, cervical, and colorectal cancer screening participation has yet to be conducted. As part of the action-research project “Miriade,” the present study aims to identifying the main theoretical frameworks and constructs adopted in the literature over the past five years to explain cancer screening participation. According to the PRISMA guidelines, a search of the MEDLINE/PubMed and PsycINFO databases was made. Empirical studies conducted from 2017 to 2021 were included. The following keywords were used: breast OR cervical OR colorectal screening AND adhesion OR participation OR engagement AND theoretical framework OR conceptual framework OR theory. Overall, 24 articles met the inclusion criteria. Each theoretical framework highlighted clinical and psychosocial constructs of cancer screening participation, focusing on the individuals (psycho-emotional functioning and skills plan) and/or the health services perspectives. Findings from the present study acknowledge the plurality of the theoretical frameworks and constructs adopted to predict or promote breast, cervical, and colorectal cancer screening adhesion and the need for new research efforts to improve the effectiveness of cancer screening promotion interventions.

Experiences of human papillomavirus self-sampling by women >60 years old: A qualitative study

BACKGROUND

Human papillomavirus (HPV) self-sampling has shown to be acceptable and feasible across cultures and effective in reaching women who do not participate in regular cervical cancer screening. However, most of these studies have included younger women. There is a lack of knowledge of how older women reason about HPV self-sampling.

OBJECTIVE

The aim of this study was to describe how women (>60 years old) experience the offering of self-sampling of HPV, compared to having a sample collected by a healthcare professional.

DESIGN AND PARTICIPANTS

The study had a qualitative explorative design. Four focus group discussions were conducted with women 60-69 years old (n = 22). Data were analysed using principles of interpretive description.

RESULTS

Five themes were identified: self-sampling-convenient and without pain, lack of knowledge, worries related to HPV self-sampling, need for information and taking a societal perspective.

CONCLUSION

Women aged >60 years found that HPV self-sampling was convenient and easy to perform. Further, they stressed the importance of being able to remain in the screening programme in advanced age and that self-sampling could be a possible solution. This study also revealed a lack of knowledge among women in this age group regarding HPV infection, how the disease is transmitted and its relation to cervical cancer.

PUBLIC CONTRIBUTION

Women who had performed HPV self-sampling participated in the focus group discussion.

Barriers to uptake of cervical cancer screening services in low-and-middle-income countries: a systematic review

OBJECTIVES

Low-and-middle-income countries (LMICs) bear a disproportionate burden of cervical cancer mortality. We aimed to identify what is currently known about barriers to cervical cancer screening among women in LMICs and propose remedial actions.

DESIGN

This was a systematic review using Medical Subject Headings (MeSH) terms in Google Scholar, PubMed, Scopus, and Web of Science databases. We also contacted medical associations and universities for grey literature and checked reference lists of eligible articles for relevant literature published in English between 2010 and 2020. We summarized the findings using a descriptive narrative based on themes identified as levels of the social ecological model.

SETTING

We included studies conducted in LMICs published in English between 2010 and 2020.

PARTICIPANTS

We included studies that reported on barriers to cervical cancer screening among women 15 years and older, eligible for cervical cancer screening.

RESULTS

Seventy-nine articles met the inclusion criteria. We identified individual, cultural/traditional and religious, societal, health system, and structural barriers to screening. Lack of knowledge and awareness of cervical cancer in general and of screening were the most frequent individual level barriers. Cultural/traditional and religious barriers included prohibition of screening and unsupportive partners and families, while social barriers were largely driven by community misconceptions. Health system barriers included policy and programmatic factors, and structural barriers were related to geography, education and cost. Underlying reasons for these barriers included limited information about cervical cancer and screening as a preventive strategy, poorly resourced health systems that lacked policies or implemented them poorly, generalised limited access to health services, and gender norms that deprioritize the health needs of women.

CONCLUSION

A wide range of barriers to screening were identified across most LMICs. Urgent implementation of clear policies supported by health system capacity for implementation, community wide advocacy and information dissemination, strengthening of policies that support women's health and gender equality, and targeted further research are needed to effectively address the inequitable burden of cervical cancer in LMICs.

Combined incentive actions, focusing on primary care professionals, to improve cervical cancer screening in women living in socioeconomically disadvantaged geographical areas: a study protocol of a hybrid cluster randomised effectiveness and implementation trial- RESISTE

INTRODUCTION

Cervical cancer (CC) causes thousands of deaths each year. Nearly 100% of cases are caused by oncogenic strains of human papillomavirus (HPV). In most industrialised countries, CC screening (CCS) is based on the detection of HPV infections. For many reasons including lower adherence to CCS, underserved women are more likely to develop CC, and die from it. We aim to demonstrate that the use of incentives could improve screening rates among this population.

METHODS AND ANALYSIS

Our cluster randomised, controlled trial will include 10 000 women aged 30-65 years eligible for CCS, living in deprived areas in four French departments, two mainlands and two overseas, and who did not perform physician-based HPV testing within the framework of the nationally organised screening programme. HPV self-sampling kit (HPVss) will be mailed to them. Two interventions are combined in a factorial analysis design ending in four arms: the possibility to receive or not a financial incentive of €20 and to send back the self-sampling by mail or to give it to a health professional, family doctor, gynaecologist, midwife or pharmacist. The main outcome is the proportion of women returning the HPVss, or doing a physician-based HPV or pap-smear test the year after receiving the HPVss. 12-month follow-up data will be collected through the French National Health Insurance database. We expect to increase the return rate of HPV self-samples by at least 10% (from 20% to 30%) compared with the postal return without economic incentive.

ETHICS AND DISSEMINATION

Ethics approval was first obtained on 2 April 2020, then on July 29 2022. The ethics committee classified the study as interventional with low risk, thus no formal consent is required for inclusion. The use of health insurance data was approved by the Commission Nationale Informatique et Libertés on 14 September 2021 (ref No 920276). An independent data security and monitoring committee was established. The main trial results will be submitted for publication in a peer-reviewed journal.

TRIAL REGISTRATION NUMBER

NCT04312178.

HPV Self-Sampling for Cervical Cancer Screening among Women Living with HIV in Low- and Middle-Income Countries: What Do We Know and What Can Be Done?

Introduction. Self-sampling has the potential to increase cervical cancer (CC) screening among women with HIV in low- and middle-income countries (LMICs). However, our understanding of how HPV self-collection studies have been conducted in women with HIV is limited. The purpose of this scoping review was to examine the extent to which the HPV self-sampling has been applied among women with HIV in LMICs. Method: We conducted multiple searches in several databases for articles published between 2000 and January 2022. With the combination of keywords relating to HPV self-sampling, LMICs, and women with HIV, we retrieved over 9000 articles. We used pre-defined inclusion and exclusion criteria to select relevant studies for this review. Once a study met the inclusion criteria, we created a table to extract each study’s characteristics and classified them under common themes. We used a qualitative descriptive approach to summarize the scoping results. Results: A total of 12 articles were included in the final review. Overall, 3178 women were enrolled in those studies and 2105 (66%) of them were women with HIV. The self-sampling participation rate was 92.6%. The findings of our study show that 43% of the women with HIV in 8 of the studies reviewed tested positive for high-risk HPV (hr-HPV) genotypes, indicating 4 out of 10 women with HIV in the studies are at risk of cervical cancer. The prevalence of the hr-HPV in women with HIV was 18% higher than that of HIV-negative women. Most women in the study found the self-sampling experience acceptable, easy to use, convenient, and comfortable. Self-sampling performance in detecting hr-HPV genotypes is comparable to clinician-performed sampling. However, limited access (i.e., affordability, availability, transportation), limited knowledge about self-screening, doubts about the credibility of self-sampling results, and stigma remain barriers to the wide acceptance and implementation of self-sampling. In conclusion, the findings of this review highlight that (a) the prevalence of hr-HPV is higher among women with HIV than HIV-negative women, (b) self-sampling laboratory performance is similar to clinician-performed sampling, (c) the majority of the women participated in self-sampling, which could likely increase the cervical cancer screening uptake, and (d) women with HIV reported a positive experience with self-sampling. However, personal, environmental, and structural barriers challenge the application of self-sampling in LMICs, and these need to be addressed.

Molecular Detection Methods in HPV-Related Cancers

Human papillomavirus (HPV) is responsible for most cervical cancers and some head and neck cancers, including oropharyngeal squamous cell carcinoma and sinonasal carcinoma. Cervical cancer is commonly diagnosed by liquid-based cytology, followed by HPV testing using commercially available DNA polymerase chain reaction (PCR), p16 immunohistochemistry (IHC), or DNA/RNA in situ hybridization. HPV in head and neck cancers is commonly diagnosed by p16 IHC or by RT-qPCR of HPV-16 E6 and E7 oncoproteins. Droplet digital PCR has been reported as an ultrasensitive and highly precise method of nucleic acid quantification for biomarker analysis and has been used to detect oncogenic HPV in oropharyngeal and cervical cancers.

Utilisation of cervical cancer screening among women living with HIV at Kenya’s national referral hospital

Background

In 2009, Kenyatta National Hospital (KNH) integrated cervical cancer screening within HIV care using visual inspection with acetic acid (VIA) and Pap smear cytology.

Objectives

We evaluated utilisation of cervical cancer screening and human papillomavirus (HPV) vaccination among women living with HIV (WLHIV) receiving HIV care at KNH.

Method

From November 2019 to February 2020, WLHIV aged ≥ 14 years were invited to participate in a survey following receipt of routine HIV services. We assessed awareness of cervical cancer, uptake of cervical cancer screening, uptake of the HPV vaccine, and barriers to utilisation of these services. In a subset of survey participants, focus group discussions (FGDs) were also conducted to identify screening barriers.

Results

Overall, 305 WLHIV participated in the survey. Median age was 36 years (interquartile range [IQR]: 28–43), 41% were married, and 38% completed secondary education. Most (90%) had HIV RNA < 1000 copies/mL. Awareness of cervical cancer was high (84%), although only 45% of WLHIV had screened for cervical cancer at the referral hospital and only 13% knew how to prevent high-risk HPV. No participants had received an HPV vaccination. Older age, higher education, and knowledge of the HPV vaccine were associated with higher likelihood of cervical cancer screening (P < 0.05). In FGDs, barriers to utilising the services included user fees, fear of the procedure impacting fertility, age and gender of the provider, and long waiting times.

Conclusion

Despite integration with HIV services, the utilisation of cervical cancer screening was low among WLHIV and implementation barriers contributed to low utilisation.

Perceptions of cervical cancer and motivation for screening among women in Rural Lilongwe, Malawi: A qualitative study

Introduction

Cervical cancer is the leading cause of cancer death among women in Malawi. Low awareness of cervical cancer and negative perceptions of screening can prevent women from participating in preventative strategies. We sought to explore perceptions and motivations for screening among women who participated in a cervical cancer screen-and-treat pilot study in rural Malawi.

Materials and methods

We conducted a qualitative sub-study of a community-based cervical cancer screen-and-treat pilot study in rural Lilongwe between July-August 2017. From October 2017-February 2018, 17 women who underwent screening using visual inspection with acetic acid (VIA) and same-day thermal ablation treatment were recruited at their 12-week follow-up visit post treatment to participate in this qualitative sub-study. Semi-structured interview guides that explored baseline knowledge of cervical cancer, perceptions, and motivation for screening were used for in-depth interviews (IDIs). IDIs were conducted in the local language, Chichewa, translated and transcribed to English. Data was analyzed using NVivo® V12.0.

Results

Findings included fatalistic views on cancer, but limited knowledge specific to cervical cancer. Misconceptions of cervical cancer screening were common; however, there was a unique understanding of screening as prevention (i.e., finding and treating early disease to prevent progression to worsening disease). This understanding appeared to stem from HIV prevention concepts known to the community. Motivations for screening included desire to know one’s health status, convenience of community-based screening, and peer encouragement.

Conclusion

Despite limited knowledge of cervical cancer and misconceptions of screening, the concept of screening for prevention, desire to know one’s health status, convenient access, and peers’ influence were motivators for participation in screening. Cervical cancer screen-and-treat programs in high HIV prevalence areas should consider utilizing language that parallels HIV prevention language to communicate the need for cervical cancer screening and treatment and utilize prevention concepts that may already be familiar to women living there.

Communities' perceptions towards cervical cancer and its screening in Wolaita zone, southern Ethiopia: A qualitative study

Background

Cervical cancer is a malignant neoplasm from cells originating in the cervix uteri. Any woman who is sexually active is at risk of getting HPV. Women in sub-Saharan Africa region have higher chance of developing the disease. There are nearly 26 million Ethiopian women who are over the age of 15 and believed to be at risk of getting HPV. Regrettably, Ethiopian women typically present for cervical cancer care at a late stage in the disease, where treatment is most ineffective.

Objectives

To explore communities’ perceptions of cervical cancer and screening among women in Wolaita zone, southern Ethiopia.

Methods

A qualitative research using focused group discussions and in-depth interviews was used to explore communities’ perceptions of cervical cancer and screening among women in Wolaita zone, southern Ethiopia from March 2018-November 2019. The study participants were men, women and communities who were residents of the study settings and were not health professionals. All focused group discussions (FGDs) and key informant interviews were transcribed and entered into Microsoft Word and thematic content analysis was done.

Results

A total of fifty-nine participants participated in both FGD (three with men and six with women) and in-depth interviews (IDIs). Most participants have not heard about cervical cancer but know cancer in general. Participants mentioned that the disease usually relates to many births and unprotected sexual intercourse but none mentioned HPV infection. Most of the participants perceive that cervical cancer is incurable and assume that it could be prevented but they think they are not vulnerable to the disease and screening is not necessary.

Conclusion

This study indicates that rural communities in the zone had limited knowledge about cervical cancer and even less about risk factors, screening, treatment and prevention. There is a great need for cancer education and prevention in Ethiopia.

Feasibility of HPV self-sampling pathway in Kathmandu Valley, Nepal using a human-centred design approach

Cervical cancer is preventable and curable yet causes almost 2000 deaths in Nepali women each year. The present study aims to explore the feasibility and acceptability of a self-sampling-based approach for cervical cancer screening in urban and peri-urban Nepal and develop pathways for self-sampling using a co-design methodology. An iterative design approach was applied. Semi-structured in-depth interviews were conducted with 30 healthy women and four women who had had a prior cancer diagnosis on topics which included: sexual and reproductive health knowledge and human papillomavirus (HPV); use of the internet/social media platforms; their views regarding acceptability and usability of the self-sampling kit and the proposed user journey. Data collection was done between December 2020 and January 2021. Seven medical experts were also interviewed to explore the current service configuration for cervical cancer screening in Nepal. Knowledge regarding HPV and its association with cervical cancer was absent for the majority of participants. Although 70% (n = 21/30) had purchased items online previously, there was a general lack of trust in online shopping. Half of the women (n = 17/30; 56.7%) expressed a willingness to self-sample and provided recommendations to improve the clarity of the instructions. The proposed user journey was considered feasible in the urban area. There is a clear unmet need for information about HPV and alternative cervical screening options in Nepal. An online pathway for self-sampling service delivery to urban women is feasible but will need to be optimally designed to address barriers such as confidence in self-sampling and trust in online purchasing.

Behavioural oncology research in Africa: Lessons from the last two decades and key considerations moving forward

OBJECTIVE

To analyse the state of behavioural oncology research in Africa and outline key considerations for future research.

METHODS

Five bibliographic databases were searched to identify original English-language articles published between January 2000 and August 2020. The Behavioural Epidemiology Framework was applied to studies with data/findings from Africa to delineate their current state. Research gaps/opportunities available for behavioural oncology research in Africa were further highlighted.

RESULTS

Two hundred eighty-seven original research with findings from Africa has been published over the last two decades, with the highest contribution arising from Nigeria, Kenya, Ethiopia and South Africa. Cervical and breast cancers were the most widely investigated. Prominently studied behaviours relate to cancer screening, health literacy, lifestyle, and vaccination. Behavioural oncology literature in Africa is generally in Phases I and III and lacks in measurement studies (<2%) and studies that seek to evaluate behaviour change/health promotion interventions (<6%) or translate them into practice (13.2%).

CONCLUSION

Embracing new and progressive approaches, including methodological/analytical paradigms and implementation science is imperative to advance the frontiers of behavioural oncology research in Africa. This calls for a responsive research approach that can mobilise multidisciplinary/multilevel coalitions, ensuring a research structure that effectively integrates behavioural research and cancer prevention/control in the region.

A systematic review of randomized control trials of HPV self-collection studies among women in sub-Saharan Africa using the RE-AIM framework

Introduction

Self-collection of samples for HPV testing may increase women’s access to cervical cancer screening in low- and middle-income settings. However, implementation remains poor in many regions. The purpose of this systematic review was to examine implementation data from randomized controlled trials evaluating human papillomavirus (HPV) self-collection testing among women in sub-Saharan Africa using the RE-AIM (Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance) framework.

Methods

We searched four electronic databases (PubMed, CINAHL, Web of Science, and Global Health) for pragmatic randomized controlled trials that promote HPV self-collection among women in sub-Saharan Africa. Study selection and data extraction were conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) checklist. Two researchers independently extracted information from each article using a RE-AIM data extraction tool. The reporting of RE-AIM dimensions was summarized and synthesized across included interventions.

Results

We identified 2008 citations, and eight studies were included. These reported on five unique interventions. The five interventions were conducted in five countries: Cameroon, Ethiopia, Kenya, Nigeria, and Uganda. Intervention reach (80%) was the most commonly reported RE-AIM dimension, followed by adoption (56%), efficacy/effectiveness (52%), implementation (47%), and maintenance (0%). All the interventions described increased uptake of HPV testing among study participants (effectiveness). However, the majority of the studies focused on reporting internal validity indicators such as inclusion criteria (100%) and exclusion criteria (100%), and few reported on external validity indicators such as participation rate (40%), intervention cost (40%), staff selection (20%), and cost of maintenance (0%).

Conclusions

Our review highlights the under-reporting of external validity indicators such as participation rate, intervention, and maintenance costs in studies of self-collection for HPV testing among women in SSA. Future research should focus on including factors that highlight internal validity factors and external validity factors to develop a greater understanding of ways to increase not only reach but also implementation and long-term maintenance of these interventions. Such data may advance the translation of HPV interventions into practice and reduce health disparities in SSA. Findings highlight the need for innovative tools such as participatory learning approaches or open challenges to expand knowledge and assessment of external validity indicators to ultimately increase the uptake of HPV testing among women in SSA.

Self-sampling as the principal modality for population based cervical screening: Five-year follow-up of the PaVDaG study

Self-sampling provides a powerful means to engage women in cervical screening. In the original Papillomavirus Dumfries and Galloway study (PaVDaG), we demonstrated cross-sectional similarity of high-risk human papillomavirus (Hr-HPV) testing on self-taken vaginal vs clinician-taken samples for the detection of cervical intraepithelial neoplasia 2 or worse (CIN2+). Few data exist on the longitudinal performance of self-sampling; we present longitudinal outcomes of PaVDaG. Routinely screened women provided a self-taken and a clinician-collected sample. Ninety-one percent of 5136 women from the original cohort completed a further screening round. Sensitivity, specificity, positive predictive value and complement of the negative predictive value of the Hr-HPV test on self-samples for detection of CIN2+ and CIN3+ up-to 5 years after testing were determined. Additionally, clinical accuracy of Hr-HPV testing on vaginal and clinician-collected samples was assessed. A total of 183 CIN2+ and 102 CIN3+ lesions were diagnosed during follow-up. Risk of CIN2+ and CIN3+ following an Hr-HPV negative self-sample was 0.6% and 0.2%, respectively, for up to 5 years after testing. The relative sensitivity for CIN3+ and specificity for ≤CIN1 of Hr-HPV testing on self-taken specimens was slightly lower vs clinician-collected samples: 0.95 (95% CI: 0.90-0.99; P^McN = .0625) and 0.98 (95% CI: 0.95-1.00; P^McN  = <.0000), respectively. The low risk of CIN2+ in women with Hr-HPV-self-sample(s) suggests, that the 3 to 5-year recall interval implemented in several cervical screening settings, based on clinician-taken samples, may be safe for self-samples. Future assessment will show if "universal" 5-year screening is appropriate for programs based on self-sampling.

Awareness about Gynecologic Cancers and Related Factors among Healthy Women: A Cross-Sectional Study

The risk of cancer-related mortality and morbidity decreases when women are aware of the risk factors for gynecologic cancers and implement strategies such as attending relevant early screening programs. This cross-sectional study conducted between August 2017 and August 2018 at a public hospital in Turkey aimed to determine the awareness about gynecologic cancers among healthy women by utilized the Krieger's ecosocial theory as a framework for the study. The study included 554 Turkish women aged 18-65 years. Data were collected using the Gynecological Cancer Awareness Scale (GCAS) and a questionnaire designed in this study. Significant differences were noted between the average GCAS score and variables such as the amount of menstrual bleeding, entering menopause, a history of reproductive system disease, regular gynecological examination (including Pap test), regular vaginal self-examination, sexually transmitted infections (STIs), genital hygiene behavior, the fear of having cancer, having knowledge about cancer, and requiring information about cancer (p < .05). Despite the high level of awareness about gynecologic cancer among these women, the lack of proper knowledge and preventive measures was high. Having knowledge about gynecologic cancers results in increased awareness; however, the level of knowledge is not sufficient to prevent gynecologic cancers, which shows the need for sufficient and effective cancer screening and education programs.

Cervical cancer prevention: Human papillomavirus testing as primary screening

Low- and middle-income countries carry a high burden of preventable cervical cancer cases and deaths. Because human papillomavirus DNA-based testing is increasingly becoming the preferred method of screening for cervical cancer prevention, this commentary discusses next steps and key considerations for its expansion.

Compliance of Professional Nurses at Primary Health Care Facilities to the South African Cervical Cancer Screening Guidelines

Despite the availability of the South African cervical cancer screening guidelines at clinics, women still present in district hospitals of Thulamela Municipality with no cervical cancer screening results. Thus, many cervical cancer screenings done at the hospitals often come back positive for cervical cancer at advanced stages. This study was conducted to investigate the compliance of professional nurses at primary health care facilities (PHCs) in Thulamela Municipality to the South African cervical cancer screening guidelines. The study adopted a qualitative approach. Purposive, non-probability sampling method was used to select PHCs and recruit eligible participants. Sample size was determined by data saturation. A digital recorder was used to log individual responses during interview sessions. Data from the digital recordings were transcribed verbatim. Results were analysed and interpreted in accordance with the consolidated criteria for reporting qualitative research (COREQ) checklist. This study established that clinic professional nurses are non-compliant to the South African cervical cancer screening guidelines owing to several challenges they face, such as inadequate knowledge of the cervical cancer screening guidelines, shortage of resources, shortage of staff and patients' factors. We recommend a strengthening of the South African cervical cancer screening guideline, in-service trainings and workshops on cervical cancer and cervical cancer screening guideline as well as improvement on patients' education.

Exploring the barriers to Pap smear test in Iranian women: a qualitative study

BACKGROUND

Cervical cancer is one of the most frequent types of cancer in females. The Pap smear is one of the most essential ways of diagnosing and screening for this malignancy, and any failure can be caused by a number of causes. The current study sought to investigate barriers to Pap smear in Iranian women.

METHOD

This qualitative content analysis study was conducted in Iran in 2019. Data was gathered through focus groups and individual semi-structured interviews with 32 women and health professionals. The interviewees were chosen using a combination of purposive and theoretical sampling. The data was then analyzed using the content analysis approach developed by Graneheim and Lundman. Guba and Lincoln's criteria for establishing trustworthiness were explored.

RESULTS

Data analysis resulted in the identification of four primary categories, seventeen subcategories, and 186 original concepts. The main categories include weakness of health system, difficult accessibility, low health literacy, and socio-cultural factors.

CONCLUSION

By informing women about the necessity and importance of Pap smear, providing the conditions, facilities, and equipment to facilitate the testing process, and paying more attention to cultural and social factors in cervical cancer and Pap smear planning, interventions, and policies, barriers to Pap testing can be eliminated.

Self-collection for HPV-based cervical screening: a qualitative evidence meta-synthesis

Background

Cervical cancer is the fourth most common cancer affecting women worldwide, with 85% of the burden estimated to occur among women in low and middle-income countries (LMICs). Recent developments in cervical cancer screening include a novel self-collection method for the detection of oncogenic HPV strains in the collected samples. The purpose of this review is to synthesise qualitative research on self-collection for HPV-based testing for cervical screening and identify strategies to increase acceptability and feasibility in different settings, to alleviate the burden of disease.

Methods

This review includes qualitative studies published between 1986 and 2020. A total of 10 databases were searched between August 2018 and May 2020 to identify qualitative studies focusing on the perspectives and experiences of self-collection for HPV-based cervical screening from the point of view of women, health care workers and other key stakeholders (i.e., policymakers). Two authors independently assessed studies for inclusion, quality, and framework thematic synthesis findings. The Socio-Ecological Model (SEM) was used to synthesize the primary studies.

Results

A total of 1889 publications were identified, of which 31 qualitative studies were included. Using an adapted version of SEM, 10 sub-themes were identified and classified under each of the adapted model’s constructs: (a) intrapersonal, (b) interpersonal, and (c) health systems/public policy. Some of the themes included under the intrapersonal (or individual) construct include the importance of self-efficacy, and values attributed to self-collection. Under the intrapersonal construct, the findings centre around the use of self-collection and its impact on social relationships. The last construct of health systems focuses on needs to ensure access to self-collection, the need for culturally sensitive programs to improve health literacy, and continuum of care.

Conclusion

This review presents the global qualitative evidence on self-collection for HPV-based testing and details potential strategies to address socio-cultural and structural barriers and facilitators to the use of self-collection. If addressed during the design of an HPV-based cervical cancer screening testing intervention program, these strategies could significantly increase the acceptability and feasibility of the intervention and lead to more effective and sustainable access to cervical screening services for women worldwide.

Multimodality screening and prevention of cervical cancer in sub-Saharan Africa: a collaborative model

PURPOSE OF REVIEW

Although cervical cancer continues to decrease in incidence throughout the developed world because of rigorous screening and vaccination campaigns, the disease remains a major cause of cancer-related morbidity and mortality in resource-limited regions including sub-Saharan Africa. This review summarizes current efforts to implement cost-effective and widespread cervical cancer education, screening, and community-based interventions in Africa and the challenges faced by local healthcare workers.

RECENT FINDINGS

Effective screening with cytology (with or without high-risk human papillomavirus [HPV] DNA testing) as well as HPV self-sampling remains problematic in African countries because of a paucity of cytopathologists and resources. Accordingly, visual inspection of the cervix with acetic acid (VIA) with cryotherapy triage has gained traction in mass-screening campaigns because of low-cost supplies.

SUMMARY

Public education to facilitate screening is essential. VIA remains a strong community-based approach. The involvement of technology in teaching local providers, advertising screenings to the community, and helping improve follow-up may also improve screening efforts. Ultimately, the best form of prevention is through HPV vaccination, which also requires implementation of ongoing public education programs.

High-risk Human Papillomavirus Messenger RNA Testing in Wet and Dry Self-collected Specimens for High-grade Cervical Lesion Detection in Mombasa, Kenya

BACKGROUND

Self-collection for high-risk human papillomavirus (hr-HPV) messenger RNA (mRNA) testing may improve cervical cancer screening. High-risk HPV mRNA with self-collected specimens stored dry could enhance feasibility and acceptance of specimen collection and storage; however, its performance is unknown. We compared the performance of hr-HPV mRNA testing with dry- as compared with wet-stored self-collected specimens for detecting high-grade squamous intraepithelial lesion or more severe (≥HSIL).

METHODS

A total of 400 female sex workers in Kenya participated (2013-2018), of which 50% were HIV positive based on enrollment procedures. Participants provided 2 self-collected specimens: one stored dry (sc-DRY) using a Viba brush (Rovers) and one stored wet (sc-WET) with Aptima media (Hologic) using an Evalyn brush (Rovers). Physician-collected specimens were collected for HPV mRNA testing (Aptima) and conventional cytology. We estimated test characteristics for each hr-HPV screening method using conventional cytology as the reference standard (≥HSIL detection). We also examined participant preference for sc-DRY and sc-WET collection.

RESULTS

High-risk HPV mRNA positivity was higher in sc-WET (36.8%) than sc-DRY samples (31.8%). Prevalence of ≥HSIL was 6.9% (10.3% HIV positive, 4.0% HIV negative). Sensitivity of hr-HPV mRNA for detecting ≥HSIL was similar in sc-WET (85%; 95% confidence interval [CI], 66%-96%), sc-DRY specimens (78%; 95% CI, 58%-91%), and physician-collected specimens (93%; 95% CI, 76%-99%). Overall, the specificity of hr-HPV mRNA for ≥HSIL detection was similar when comparing sc-WET with physician collection. However, specificity was lower for sc-WET (66% [61%-71%]) than sc-DRY (71% [66%-76%]). Women preferred sc-DRY specimen collection (46.1%) compared with sc-WET (31.1%). However, more women preferred physician collection (63.9%) compared with self-collection (36.1%).

CONCLUSIONS

Self-collected stored-dry specimens seemed to perform similarly to sc-WET for the detection of ≥HSIL.

Women's experiences in a community-based screen-and-treat cervical cancer prevention program in rural Malawi: a qualitative study

BACKGROUND

Malawi has the world's highest cervical cancer incidence and mortality due to high rate of HIV coupled with inadequate screening and treatment services. The country's cervical cancer control program uses visual inspection with acetic acid (VIA) and cryotherapy, but screening is largely limited by poor access to facilities, high cost of cryotherapy gas, and high loss-to-follow-up. To overcome these limitations, we implemented a community-based screen-and-treat pilot program with VIA and thermocoagulation. Through a qualitative study, we explore the experiences of women who underwent this community-based pilot screening program.

METHODS

We implemented our pilot program in rural Malawi and conducted an exploratory qualitative sub-study. We conducted in-depth interviews with women who were treated with thermocoagulation during the program. We used semi-structured interviews to explore screen-and-treat experience, acceptability of the program and attitudes towards self-sampling for HPV testing as an alternative screening method. Content analysis was conducted using NVIVO v12.

RESULTS

Between July - August 2017, 408 participants eligible for screening underwent VIA screening. Thirty participants had VIA positive results, of whom 28 underwent same day thermocoagulation. We interviewed 17 of the 28 women who received thermocoagulation. Thematic saturation was reached at 17 interviews. All participants reported an overall positive experience with the community-based screen-and-treat program. Common themes were appreciation for bringing screening directly to their villages, surprise at the lack of discomfort, and the benefits of access to same day treatment immediately following abnormal screening. Negative experiences were rare and included discomfort during speculum exam, long duration of screening and challenges with complying with postprocedural abstinence. Most participants felt that utilizing self-collected HPV testing could be acceptable for screening in their community.

CONCLUSIONS

Our exploratory qualitative sub-study demonstrated that the community-based screen-and-treat with VIA and thermocoagulation was widely accepted. Participants valued the accessible, timely, and painless thermocoagulation treatment and reported minimal side effects. Future considerations for reaching rural women can include community-based follow-up, cervical cancer education for male partners and self-sampling for HPV testing.

Human Papilloma Virus self-sampling performance in low- and middle-income countries

Background

Screening for HPV has led to significant reductions in cervical cancer deaths in high-income countries. However, the same results have not been achieved in low- and middle-income countries (LMICs). HPV self-sampling is a novel approach that could improve screening rates.

Methods

This study’s objective is to summarize the recent literature on HPV self-sampling in LMICs, focusing on sensitivity/specificity, and feasibility/acceptability of self-sampling compared to traditional screening methods. We conducted a PubMed search for articles published in English within the last 10 years on self-sampling in LMICs.

Results

Fifty eligible articles from 26 countries were included, 19 of which came from sub-Saharan Africa and 18 from Latin America/Caribbean. Seven studies examined sensitivity, with five reporting rates higher than 91%. Six reported on specificity, which was also very high at 86–97.8%. Six studies examined self-sampling concordance with provider-collected sampling, with concordance rates ranging from 87 to 97.5%. A total of 38 studies examined the feasibility/acceptability of HPV self-sampling. Participation rates were very high in all studies, even when self-sampling was done at participants’ homes (over 89% participation). Overall, participants reported that HPV self-sampling was easy to perform (75–97%, 18 studies), painless (60–90%, nine studies), and preferred over provider-collected sampling (57–100%, 14 studies). Eight studies reported follow-up rates for participants who completed self-sampling; however, these rates varied widely-from 13.7 to 90%. The major benefits of self-sampling include convenience of screening from home, less embarrassment, and less travel. Improved education and awareness of self-sampling, combined with support from community health workers, could reduce perceptions of self-sampling being inferior to provider-collected sampling. Improving follow-up of abnormal results and improving linkages to treatment are also essential.

Conclusion

Our literature review highlights HPV self-sampling is a well-performing test that shows promise in terms of expanding screening efforts for the prevention of cervical cancer-related deaths in LMICs.

Assessing the feasibility of a rapid, high-volume cervical cancer screening programme using HPV self-sampling and digital colposcopy in rural regions of Yunnan, China

OBJECTIVE

Implementation of a novel, rapid, high-volume, see-and-treat cervical cancer screening programme using self-swab human papillomavirus (HPV) testing and digital colposcopy in underserved regions of Yunnan China.

DESIGN

480-980 women per day self-swabbed for high-risk HPV (hrHPV+). Four careHPV machines (Qiagen) were run simultaneously to test the specimens. All hrHPV+ patients were contacted the same day and digital colposcopy was performed with the enhanced visual assessment system (MobileODT). Digital images were obtained, and all suspected lesions were biopsied and then treated.

SETTING

Rural and underserved areas of the Yunnan province, Kunming municipality.

PARTICIPANTS

3600 women, mean age 50.2 years, who had never been screened for cervical cancer. The women were of the Yi, Hui, Dai and Han ethnicities.

INTERVENTIONS

Cryotherapy was performed on all lesions suspicious for cervical intraepithelial neoplasia (CIN) 1 and loop electrosurgical excision procedure was performed on all lesions suspicious for ≥CIN2. Endocervical curettage was performed if the transformation zone was not fully visualised.

RESULTS

216 women (6%) were hrHPV+. 168 underwent same-day colposcopy (23 CIN1, 17≥CIN2). Digital colposcopy was able to identify 15 of 16 (93.8%)≥CIN2 lesions.

CONCLUSIONS

This study illustrates a high-volume, rapid and practical strategy that can be used to screen and treat an ethnically diverse group of Chinese women. First, HPV self-sampling allows large numbers of women to be screened rapidly and relatively inexpensively. Only hrHPV+ women will then require further evaluation. Digital colposcopy is then performed on hrHPV+ women with a portable digital colposcope. The high-resolution images obtained can facilitate appropriate same-day treatment as they are able to accurately distinguish between CIN1 and ≥CIN2 lesions.

A systematic review of self-sampling for HPV testing in Africa

BACKGROUND

Human papillomavirus (HPV) testing may be feasible for primary cervical cancer screening in low-resource countries.

OBJECTIVE

To compare self-sampling by women with clinician-performed sampling for HPV testing in Africa.

SEARCH STRATEGY

MEDLINE, Google scholar, EMBASE, and several journals were searched from 2000 until 2015 using relevant terms.

SELECTION CRITERIA

Selected studies compared self-sampled and clinician-sampled HPV tests.

DATA COLLECTION AND ANALYSIS

Data extraction forms included description of the type of HPV screening, description of any additional intervention components, study design, sample size, follow-up periods, analytic approach, reported numerical outcomes, results, and limitations.

RESULTS

Twenty-five studies were identified. Women of a wide age range were successful at self-sampling in many African countries. More than 95% of self-samples yielded HPV DNA results. The concordance in test results between self-collected samples and clinician-collected samples was reasonably high in most studies. In all studies, the quality of cytology from self-sampling matched that of clinician-sampling. Women were generally positive about self-collection, but noted some concerns.

CONCLUSION

Self-sampling for HPV DNA testing seems to represent a feasible alternative to the Pap test. Further research is needed to provide a solid evidence base to inform using of self-sampling for HPV DNA testing for primary cervical cancer screening.

'I'm here to save my life': a qualitative study of experiences navigating a cryotherapy referral system for human papillomavirus-positive women in western Kenya

BACKGROUND

We sought to understand the beliefs, social norms and logistical factors that affect human papillomavirus (HPV)-positive women's uptake of cryotherapy treatment as part of a two-part cervical cancer screening strategy in rural Kenya.

METHODS

In-depth interviews within a parent cluster-randomised trial.

SETTING

Government-run county hospital in western Kenya.

PARTICIPANTS

273 of 372 (73.4%) HPV-positive women who underwent cryotherapy RESULTS: Many women feared that an HPV infection meant they would develop cancer. Almost all women reported initial fear of the treatment procedure, followed by a more positive experience than anticipated. Lacking funds for transportation to the treatment site was the most common barrier. Women felt that decentralised treatment would be the most important facilitator of greater access. Spousal encouragement and financial support were key facilitators of treatment access, however many women felt that other husbands in the community would not be supportive. Women described successfully acquiring treatment as empowering, and almost all would recommend seeking cryotherapy to other women who test HPV-positive. Most felt eager to share their own experiences with others to encourage treatment.

CONCLUSIONS

The main facilitators of treatment access were understanding of the health risks and sense of empowerment. A decentralised treatment model or transportation support may facilitate access, along with improved health messaging about HPV infection, cancer and the treatment process. Focusing on women's personal feelings of empowerment may further improve uptake and satisfaction. These data will be used to design a strategy to improve linkage to treatment.
