Experiences and perspectives regarding human papillomavirus self-sampling in sub-Saharan Africa: A systematic review of qualitative evidence. Heliyon 2024; 10:e32926. [PMID: 39021965 PMCID: PMC11253232 DOI: 10.1016/j.heliyon.2024.e32926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 05/08/2024] [Accepted: 06/12/2024] [Indexed: 07/20/2024] Open
Abstract
Introduction Cervical cancer screening coverage remains low in sub-Saharan Africa (SSA) due to limited access and low uptake of available services by women. The use of HPV-based self-sampling intervention for cervical cancer screening has the potential to increase screening coverage in the region. This study aimed to analyse qualitative evidence on the experiences and perspectives of women, healthcare workers, and policymakers regarding HPV self-sampling. Methods We reviewed qualitative studies from January 2011 to March 2023 in PubMed, Scopus, Medline Ovid, Cochrane, and WEB of Science databases for articles with qualitative data on HPV self-sampling from different countries in SSA. The socio-ecological model was used to guide data analysis and the study findings. Results Thirteen qualitative studies were included for analysis, and they revealed themes under the intrapersonal, interpersonal, community, and health systems constructs of the Socio-ecological model. Intrapersonal themes included the acceptability of self-sampling, self-efficacy, and the perceived value of self-sampling. The interpersonal construct had themes such as women's spousal relationships, peer support, and the health worker's relationship with the women. The community construct had two themes: social stigma and misinformation, and the influence of cultural norms and religion. Finally, the health systems construct had themes such as the setting for self-sampling, follow-up availability of treatment services and education and awareness. Conclusion This study highlights the factors influencing the acceptability and uptake of an HPV-based self-sampling intervention for cervical cancer screening in SSA. Considering these findings when designing interventions in SSA is crucial to ensure acceptance and demand among end-users. Self-sampling interventions offer the potential to reach many unscreened women and increase cervical cancer screening coverage in SSA, which is an essential strategy towards achieving the World Health Organisation's cervical cancer elimination targets by the close of the century.

Abstract
PURPOSE With the inclusion of primary HPV testing in 2018 U.S. Preventive Services Taskforce guidelines, at-home HPV self-sampling may provide a future option for cervical cancer screening, especially among hard-to-reach populations in the U.S. This study evaluated the association of implementation preferences with the willingness of at-home HPV self-sampling. METHODS We conducted a cross-sectional study in 2018 among U.S. women ages 30-65 years, without a hysterectomy (n = 812). The outcome was willingness to have at-home HPV self-sampling (yes/no). Primary predictor variables (i.e., information source, methods of payment, methods of sending or receiving self-sampling kits) measured self-sampling implementation preferences. Adjusted logistic regression identified associations with willingness to have at-home HPV self-sampling. RESULTS Participants who preferred receiving information from healthcare providers (OR = 2.64; 95% CI 1.54,4.52) or from media or other sources (OR = 2.30; 95% CI 1.51,3.48) had higher HPV self-sampling willingness than participants who did not prefer those sources. Participants who did not want to pay for self-sampling (OR = 0.21; 95% CI 0.14,0.32) or did not know if they would pay for self-sampling (OR = 0.35; 95% CI 0.22,0.54) had lower odds of HPV self-sampling willingness compared to participants willing to pay. Participants who did not know which method they preferred for receiving a self-sampling kit (OR = 0.15, 95% CI 0.07,0.31) or preferred delivering the sample to the lab themselves (OR = 0.59; 95% CI 0.36,0.96) had lower odds for self-sampling willingness compared to participants who preferred the mail. CONCLUSION Understanding the preferences of women regarding the implementation of HPV self-sampling can improve uptake in cervical cancer screening, especially among hard-to-reach populations.

Co-creation of human papillomavirus self-sampling delivery strategies for cervical cancer screening in rural Zimbabwe: nominal group technique. Front Public Health 2023; 11:1275311. [PMID: 38035305 PMCID: PMC10687562 DOI: 10.3389/fpubh.2023.1275311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 10/24/2023] [Indexed: 12/02/2023] Open
Abstract
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.

Self-sampling and HPV DNA testing for cervical precancer screening in a cohort of nuns in Ghana: a cross-sectional cohort study. EClinicalMedicine 2023; 63:102183. [PMID: 37692077 PMCID: PMC10484965 DOI: 10.1016/j.eclinm.2023.102183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 08/10/2023] [Accepted: 08/14/2023] [Indexed: 09/12/2023] Open
Abstract
Background The need for cervical cancer screening has been emphasised in at-risk cohorts of women to reduce their risk of cervical cancer. Some women with decreased risk of acquiring human papillomavirus (HPV) infections, such as Catholic nuns, receive less attention and on occasion are missed in cervical cancer screening programmes. This study aimed to determine the high-risk HPV (hr-HPV) prevalence in such a cohort to emphasise the need for cervical precancer screening among all women. To improve compliance, we employed self-sampling. Methods This descriptive cross-sectional cohort study involved the data of 105 Catholic nuns subjected to cervical screening using self-samples in the Greater Accra, Volta, and Central regions of Ghana between June 4, 2022 and June 30, 2022. hr-HPV testing was performed on self-samples using the MA-6000 HPV DNA platform. Screen-positive nuns underwent follow-up pap smears and EVA colposcopy. In addition to descriptive analysis, univariate and multivariable nominal logistic regression was used to explore the relationship between hr-HPV positivity and selected continuous and categorical factors. Findings 105 nuns from three convents were screened with hr-HPV DNA testing (MA-6000). Twenty-five tested positive for hr-HPV (prevalence of 23.8% (95% CI, 15.7-32.0) [HPV 18 only (n = 2, 1.9%), non-HPV 16/18 genotypes (others) (n = 22, 21.0%), and mixed infection with HPV 16 and other genotype(s) (n = 1, 1.0%)]. Pap smears for all 25 hr-HPV-positives came in as negative for intraepithelial lesions or malignancy, whereas EVA mobile colposcopy showed minor abnormal findings in two (8.0%; 95% CI, 1.0-26.0), both of whom were managed conservatively. Interpretation Our findings suggest that the hr-HPV prevalence in this cohort of nuns is similar to that of the general population. To meet the World Health Organization's target for cervical cancer elimination, it is important that all women are given access to cervical cancer screening and preventative services. Further, increasing 'anonymity' and privacy among nuns through self-sampling may be crucial to expanding choice, coverage, and uptake of screening in support of their health rights. Funding None.

Mapping digital health ecosystems in Africa in the context of endemic infectious and non-communicable diseases. NPJ Digit Med 2023; 6:97. [PMID: 37237022 PMCID: PMC10213589 DOI: 10.1038/s41746-023-00839-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 05/05/2023] [Indexed: 05/28/2023] Open
Abstract
Investments in digital health technologies such as artificial intelligence, wearable devices, and telemedicine may support Africa achieve United Nations (UN) Sustainable Development Goal for Health by 2030. We aimed to characterize and map digital health ecosystems of all 54 countries in Africa in the context of endemic infectious and non-communicable diseases (ID and NCD). We performed a cross-national ecological analysis of digital health ecosystems using 20-year data from the World Bank, UN Economic Commission for Africa, World Health Organization, and Joint UN Programme on HIV/AIDS. Spearman's rank correlation coefficients were used to characterize ecological correlations between exposure (technology characteristics) and outcome (IDs and NCDs incidence/mortality) variables. Weighted linear combination model was used as the decision rule, combining disease burden, technology access, and economy, to explain, rank, and map digital health ecosystems of a given country. The perspective of our analysis was to support government decision-making. The 20-year trend showed that technology characteristics have been steadily growing in Africa, including internet access, mobile cellular and fixed broadband subscriptions, high-technology manufacturing, GDP per capita, and adult literacy, while many countries have been overwhelmed by a double burden of IDs and NCDs. Inverse correlations exist between technology characteristics and ID burdens, such as fixed broadband subscription and incidence of tuberculosis and malaria, or GDP per capita and incidence of tuberculosis and malaria. Based on our models, countries that should prioritize digital health investments were South Africa, Nigeria, and Tanzania for HIV; Nigeria, South Africa, and Democratic Republic of the Congo (DROC) for tuberculosis; DROC, Nigeria, and Uganda for malaria; and Egypt, Nigeria, and Ethiopia for endemic NCDs including diabetes, cardiovascular disease, respiratory diseases, and malignancies. Countries such as Kenya, Ethiopia, Zambia, Zimbabwe, Angola, and Mozambique were also highly affected by endemic IDs. By mapping digital health ecosystems in Africa, this study provides strategic guidance about where governments should prioritize digital health technology investments that require preliminary analysis of country-specific contexts to bring about sustainable health and economic returns. Building digital infrastructure should be a key part of economic development programs in countries with high disease burdens to ensure more equitable health outcomes. Though infrastructure developments alongside digital health technologies are the responsibility of governments, global health initiatives can cultivate digital health interventions substantially by bridging knowledge and investment gaps, both through technology transfer for local production and negotiation of prices for large-scale deployment of the most impactful digital health technologies.

Abstract
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.

Abstract
BACKGROUND To identify effective interventions to increase the uptake of cervical cancer screening (CCS) for low-and middle-income countries (LMICs). METHODS We searched PubMed, CENTRAL, ISI Web of Sciences, Scopus, OVID (Medline), CINAHL, LILACS, CNKI and OpenGrey for randomized controlled trials (RCTs) and cluster RCTs conducted in LMICs from January 2000 to September 2021. Two reviewers independently screened studies, extracted data, assessed risk of bias and certainty of evidence. Meta-analyses with random-effects models were conducted for data synthesis. RESULTS We included 38 reports of 24 studies involving 318,423 participants from 15 RCTs and nine cluster RCTs. Single interventions may increase uptake of CCS when compared with control (RR 1.47, 95% CI 1.19 to 1.82). Self-sampling of Human Papillomavirus (HPV) testing may increase uptake of CCS relative to routine Visual Inspection with Acetic Acid (RR 1.93, 95% CI 1.66 to 2.25). Reminding with phone call may increase uptake of CCS than letter (RR 1.72, 95% CI 1.27 to 2.32) and SMS (RR 1.59, 95% CI 1.19 to 2.13). Sending 15 health messages may increase uptake of CCS relative to one SMS (RR 2.75, 95% CI 1.46 to 5.19). Free subsidized cost may increase uptake of CCS slightly than $0.66 subsidized cost (RR 1.60, 95% CI 1.10 to 2.33). Community based HPV test may increase uptake of CCS slightly in compared to hospital collected HPV (RR 1.67, 95% CI 1.53 to 1.82). The evidence is very uncertain about the effect of combined interventions on CCS uptake relative to single intervention (RR 2.20, 95% CI 1.54 to 3.14). CONCLUSIONS Single interventions including reminding with phone call, SMS, community self-sampling of HPV test, and free subsidized services may enhance CCS uptake. Combined interventions, including health education interventions and SMS plus e-voucher, may be better than single intervention. Due to low-certainty evidences, these findings should be applied cautiously.

Comparison of human papillomavirus-based cervical cancer screening strategies in Tanzania among women with and without HIV. Int J Cancer 2023; 152:686-696. [PMID: 36093587 PMCID: PMC10087897 DOI: 10.1002/ijc.34283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 08/22/2022] [Indexed: 02/01/2023]
Abstract
Cervical cancer is the most common female cancer in Eastern Africa, and the World Health Organization (WHO) recommends human papillomavirus (HPV)-based screening as a key element to eliminate the disease. In this cross-sectional study from Tanzania, we compared nine HPV-based cervical cancer screening strategies, including HPV testing at standard cut-off; HPV testing at increased viral load cut-offs; HPV testing with partial/extended genotyping, and HPV testing with visual inspection with acetic acid (VIA). We pooled data collected during 2008 to 2009 and 2015 to 2017 from 6851 women aged 25 to 65. Cervical cytology samples were HPV tested with Hybrid Capture 2, and HPV positive samples were genotyped with INNO-LiPA Extra II. Human immunodeficiency virus (HIV) testing and VIA were done according to local standards. We calculated sensitivity, specificity, positive and negative predictive value of screening strategies, with high-grade cytological lesions as reference, separately for women with and without HIV. HPV testing at standard cut-off (1.0 relative light units [RLU]) had highest sensitivity (HIV+: 97.8%; HIV-: 91.5%), but moderate specificity (HIV+: 68.1%; HIV-: 85.7%). Increasing the cut-off for HPV positivity to higher viral loads (5.0/10.0 RLU) increased specificity (HIV+: 74.2%-76.5%; HIV-: 89.5%-91.2%), with modest sensitivity reductions (HIV+: 91.3%-95.7%; HIV-: 83.5%-87.8%). Limiting test positivity to HPV types 16/18/31/33/35/45/52/58 improved specificity while maintaining high sensitivity (HIV+: 90.2%; HIV-: 81.1%). Triage with VIA and/or partial genotyping for HPV16/18 or HPV16/18/45 had low sensitivities (≤65%). In conclusion, HPV testing alone, or HPV testing with extended genotyping or increased viral load cut-offs, may improve cervical cancer screening in Sub-Saharan Africa.

Kurtay S, Ali KY, Hussein AI. Frequency of cervical premalignant lesions in the gynecologic patients of a tertiary hospital in Mogadishu, Somalia. BMC Womens Health 2022; 22:501. [PMID: 36476212 PMCID: PMC9727848 DOI: 10.1186/s12905-022-02106-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Accepted: 12/01/2022] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Cervical cancer is the fourth most common cancer worldwide and is the most frequently diagnosed cancer in 23 countries and the most common cause of death in 36 countries, mostly from Sub-Saharan African countries. Cervical screening is a key element to reduce the incidence and mortality of cervical cancer. Cancer screening is low in Sub-Saharan Africa. This study aims to provide information about cervical premalignant lesions frequency in Somalia. METHODS The pathology results of cervicovaginal smear samples obtained from patients aged 25-65 years who applied to the gynecology outpatient clinic between October 5 and December 5, 2021 were analyzed retrospectively. SPSS 22.0 was used for the statistical analysis of the data. RESULT Among the 497 results, 63 premalignant lesions were detected. The rate of premalignant lesions (63/497) was found to be 12.3%. The most common premalignant lesion was atypical squamous cells of undetermined significance (ASC-US). CONCLUSION In this study, the frequency of cervical premalignant lesions in Somalia was found to be higher than in the literature. Vaccination, screening, and early diagnosis are the most important components in the fight against cervical cancer. Access to vaccination, screening, and early diagnosis, which are the most important components in the fight against cervical cancer in Somalia, will be possible with the cooperation of the national health system and international organizations.

The Influence of Vaginal HPV Self-Sampling on the Efficacy of Populational Screening for Cervical Cancer-An Umbrella Review. Cancers (Basel) 2022; 14:5913. [PMID: 36497396 PMCID: PMC9740498 DOI: 10.3390/cancers14235913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/23/2022] [Accepted: 11/29/2022] [Indexed: 12/05/2022] Open
Abstract
INTRODUCTION Early detection of cervical cancer is a matter of great importance as the prognosis depends on the stage of the disease. The objective of the study consisted in the assessment of the impact of HPV self-sampling on the efficacy of populational screening programs aimed at early CC detection. METHODS The analysis was performed taking into account the Cochrane Collaboration guidelines for systematic reviews. The analyzed articles were searched for in the following databases: Medline (PubMed), Embase (Ovid), and Cochrane Library. RESULTS From a total of 60 citations, 16 studies were included in this review. The HPV test is highly sensitive and specific although the diagnostic accuracy of tests carried out in self-collected samples is slightly lower than that of tests carried out in samples collected by clinicians. The results of meta-analyses for HPV tests performed on self-collected samples indicate that the sensitivity for detecting CIN2+ ranges from 74% to 86% (depending on the publication and the analyzed population), and for CIN3+ from 75% to 86%. One publication showed a clearly lower sensitivity of 42% in detecting CIN3+, but the result is for a high-risk population and comes from only 1 RCT. The specificity of the assay exceeds 80% and 79.5% with regard to the detection of CIN2+ and CIN3+, respectively. As shown by the studies included in the review, both the offering of HPV self-sampling kits to patients and the mailing of such kits significantly increase the uptake of and participation in cervical cancer screening programs. In addition, self-sampling was found to be acceptable by the female subjects. CONCLUSIONS HPV self-sampling is an innovative and cost-effective way to perform screening tests. In addition, self-sampling significantly increases the willingness to participate in screening programs among female subjects.

Performance of HPV testing, Pap smear and VIA in women attending cervical cancer screening in Kilimanjaro region, Northern Tanzania: a cross-sectional study nested in a cohort. BMJ Open 2022; 12:e064321. [PMID: 36316070 PMCID: PMC9628663 DOI: 10.1136/bmjopen-2022-064321] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Accepted: 10/12/2022] [Indexed: 12/01/2022] Open
Abstract
OBJECTIVE There is a concern about performance of the screening approaches, where information on the quality of novel and affordable screening approaches that will perform well in remote areas is warranted. This lack of information makes it difficult to prioritise resource use in efforts to improve cervical cancer outcomes. We aimed to compare the diagnostic value of human papillomavirus (HPV) testing on self-collected samples, Pap smear and visual inspection of the cervix with acetic acid (VIA) tests for detection of high-grade cervical intraepithelial neoplasia or worse (CIN2+). DESIGN A combined cross-sectional and cohort study. SETTING Three primary healthcare centres in Kilimanjaro region, Tanzania. PARTICIPANTS 1620 women undergoing cervical cancer screening from December 2018 to September 2021. Inclusion criteria were being aged 25-60 years, and no history of premalignant or cervical cancer. Exclusion criteria were overt signs of cancer and previous hysterectomy. INTERVENTIONS Participants underwent HPV self-sampling with Evalyn Brush and Care HPV kit assay was used to determine prevalence of high-risk HPV infection. Women with positive HPV test were together with a random sample of HPV negative women scheduled for follow-up where VIA was performed, and Pap smear and cervical biopsies obtained. RESULTS Of 1620 women enrolled, 229 (14.1%) were HPV positive and 222 of these attended follow-up together with 290 (20.8%) women with negative HPV test. On VIA, 17.6% were positive. On Pap smear, 8.0% were classified as high-grade squamous intraepithelial lesion. The sensitivity and specificity, respectively, of the various tests, compared with histopathology for the detection of CIN2+ were: HPV test 62.5%, 59.3%; Pap smear 82.8%, 82.1% and; VIA 48.4%, 56.8%. When combined, the sensitivity and specificity for HPV and Pap smear were 90.6%, 70.6% while HPV and VIA were 65.6% and 75.5% for the detection of CIN2+. CONCLUSIONS The performance of care HPV testing on self-collected samples opens the possibility of increasing coverage and early detection in resource-constrained settings.

BMJ Open 2022; 12:e056140. [PMID: 35501094 PMCID: PMC9062804 DOI: 10.1136/bmjopen-2021-056140] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 04/16/2022] [Indexed: 12/04/2022] Open
Abstract
INTRODUCTION Evidence shows that women in sub-Saharan Africa have high rates of cervical cancer (CC) mortality compared with women in high-income countries. Effective screening programmes have significantly reduced the burden of CC in high-income countries. Self-sampling for human papillomavirus testing (HPVSS) has been reported to increase the participation and engagement of women in CC screening. Before HPVSS can be introduced for CC screening there is a need to establish its acceptability among end-users to ensure the increase in CC screening rates. Here, we outline a protocol for a scoping review aimed at mapping literature on the use and acceptability of HPVSS for screening CC in sub-Saharan Africa to reveal gaps to guide future research and practice. METHOD The scoping review protocol was developed according to Arksey and O'Malley and Levac et al, and guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. We will search Scopus, PubMed, Medline Ovid, Cochrane and Web of Science databases for evidence on the use and acceptability of HPVSS published between January 2011 and July 2021. We will also search grey literature in the form of dissertations/theses, conference proceedings, websites of international organisations such as the WHO, and relevant government reports reporting evidence on HPVSS programmes for screening CC among women in sub-Saharan Africa. ETHICS AND DISSEMINATION No ethical approval is needed for the study as it will not include animals or human participants. The results of the proposed scoping review will be disseminated electronically in peer-reviewed journals, in print and through conference presentations.

Abstract
Precision cancer prevention as it is currently envisioned is a targeted, molecular-based approach to intercept carcinogenesis before cancer develops or before it becomes untreatable. Unfortunately, due to systemic biases, current precision cancer prevention interventions might not be effective in all populations, especially in minoritized communities. In addition, not all cancer risk is attributable to genetic or even biological factors, but includes social determinants of health (SDH). Here, we propose a broader framework for precision cancer prevention, anchored in optimizing the benefits to harms for all people. We propose that precision cancer prevention considers not only what is being delivered, but also for whom, where, and how, with a goal of achieving cancer prevention health equity.
