ABSTRACT

Methylation markers have shown potential for triaging high-risk HPV-positive (hrHPV+) women to identify those at increased risk of invasive cervical cancer (ICC). Our aim was to assess the performance of the S5 DNA methylation classifier for predicting incident high-grade cervical intraepithelial neoplasia (CIN) and ICC among hrHPV+ women in the ARTISTIC screening trial cohort. The S5 classifier, comprising target regions of tumour suppressor gene EPB41L3 and L1 and L2 regions of HPV16, HPV18, HPV31, and HPV33, was assayed by pyrosequencing in archived hrHPV+ liquid-based samples from 343 women with high-grade disease (139 CIN2, 186 CIN3, and 18 ICC) compared to 800 hrHPV+ controls. S5 DNA methylation correlated directly with increasing severity of disease and inversely with lead time to diagnosis. S5 could discriminate between hrHPV+ women who developed CIN3 or ICC and hrHPV+ controls (p <.0001) using samples taken on average 5 years before diagnosis. This relationship was independent of cytology at baseline. The S5 test showed much higher sensitivity than HPV16/18 genotyping for identifying prevalent CIN3 (93% vs. 61%, p = .01) but lower specificity (50% vs. 66%, p <.0001). The S5 classifier identified most women at high risk of developing precancer and missed very few prevalent advanced lesions thus appearing to be an objective test for triage of hrHPV+ women. The combination of methylation of host and HPV genes enables S5 to combine the predictive power of methylation with HPV genotyping to identify hrHPV-positive women who are at highest risk of developing CIN3 and ICC in the future.

ABSTRACT

An increase in cervical cancer incidence in Sweden from 2014 to 2015 has been attributed to an increase in false-negative cytological findings before cancer diagnoses. Years later, we performed a long-term follow-up to investigate whether the problem persisted. At each calendar year from 2016 to 2020, we identified women with prior normal cervical screening results through linkage to the Swedish National Cervical Screening Registry. We reported their incidence rates (IRs) of invasive cervical cancer in consecutive years and compared the IRs over time. For the years 2016 to 2020, there was no overall change in cervical cancer incidence after two normal cytology in the last two screening intervals. However, there was a further 62% increase among women 50 to 60 years of age with normal cytology in the past two screening intervals. The incidence rate of cervical cancer was high among nonscreened women and low among HPV-screened women with negative results, with no trends over time. Our results imply that the previously reported decrease in sensitivity of cervical cytology is persisting. Although primary cytology screening is no longer used, cytology is used in triaging among HPV-positive women. Our findings suggest that improved triaging is needed, for example, improved quality assurance and/or use of alternative triage tests.

ABSTRACT

BACKGROUND: Cervicovaginal microbiome plays an important role in the persistence of HPV infection and subsequent disease development. However, cervicovaginal microbiota varied cross populations with different habits and regions. Identification of population-specific biomarkers from cervicovaginal microbiota and host metabolome axis may support early detection or surveillance of HPV-induced cervical disease at all sites. Therefore, in the present study, to identify HPV-specific biomarkers, cervicovaginal secretion and serum samples from HPV-infected patients (HPV group, n = 25) and normal controls (normal group, n = 17) in Xichang, China were collected for microbiome (16S rRNA gene sequencing) and metabolome (UHPLC-MS/MS) analysis, respectively. RESULTS: The results showed that key altered metabolites of 9,10-DiHOME, α-linolenic acid, ethylparaben, glycocholic acid, pipecolic acid, and 9,12,13-trihydroxy-10(E),15(Z)-octadecadienoic acid, correlating with Sneathia (Sneathia_amnii), Lactobacillus (Lactobacillus_iners), Atopobium, Mycoplasma, and Gardnerella, may be potential biomarkers of HPV infection. CONCLUSION: The results of current study would help to reveal the association of changes in cervicovaginal microbiota and serum metabolome with HPV infections.

ABSTRACT

OBJECTIVE: In response to the World Health Organization's global call to eliminate cervical cancer, many countries have targets to implement human papillomavirus (HPV) primary screening. Social media may offer opportunities to promote uptake of HPV screening. We aimed to describe the extent of the scientific literature regarding social media research on HPV, cervical cancer and cervical screening. METHODS: Seven databases were searched for peer-reviewed English-language studies related to social media research and HPV, cervical cancer and cervical screening published up to November 2023. One reviewer completed the title/abstract screening and two reviewers independently reviewed full-text articles. Data extraction was carried out by one reviewer and verified by a second reviewer. Information such as the research topic, social media platform of interest, participant characteristics, methods, analysis type, outcome measures, and key findings were collected. RESULTS: In the 58 articles included, researchers used social media in the following ways: evaluate content, recruit participants or disseminate a survey/questionnaire, disseminate health communication content, examine the relationship between social media use and outcomes, and to conduct experiments testing the effects of social media content on outcomes. Twitter and Facebook were the most common platforms mentioned. Four articles explicitly mentioned theory. CONCLUSIONS: Opportunities for research are identified such as further exploration of how newer social media platforms such as Instagram and TikTok can be used to share HPV content, examination of appropriate images for effective communication, and determining key features of social media content to promote information sharing and improve cervical screening knowledge, attitudes and behaviours.

ABSTRACT

OBJECTIVE: To understand whether self-sampling can reduce carbon emissions (CO2 e) from the NHS cervical screening programme (NHSCSP) by comparing the carbon footprint of three sampling strategies: routine cervical sampling, vaginal self-sampling and first-void (FV) urine collection. DESIGN: Descriptive study. SETTING: National Health Service (NHS), United Kingdom (UK). POPULATION OR SAMPLE: Patients aged 25-64 years eligible for cervical screening in the UK. METHODS: A carbon footprint analysis was undertaken for three cervical screening sampling approaches, from point of invitation to screening through to preparation for transport to the laboratory for HPV testing. A combination of primary and secondary data were used, with a bottom-up approach applied to collection of primary data. MAIN OUTCOME MEASURES: We report CO2 e per sampling approach, which is the unit used to express carbon footprint and harmonise the contributions of greenhouse gases with different global warming potentials. RESULTS: The total carbon footprint of routine cervical sampling is 3670 g CO2 e. By comparison, vaginal self-sampling had a total carbon footprint of 423 g CO2 e, and FV urine sampling 570 g CO2 e. The largest share of emissions for routine sampling was attributable to the carbon footprint associated with an appointment in a primary care setting, which totalled 2768 g CO2 e. CONCLUSIONS: Routine cervical sampling is up to 8.7-fold more carbon-intensive than self-sampling approaches with equivalent effectiveness. We found negligible differences in the carbon footprint of alternative self-sampling methods, supporting the need for an informed choice of screening options for participants, which includes sharing information on their environmental impacts.

ABSTRACT

OBJECTIVE: To evaluate the sensitivity of human papillomavirus (HPV) tested urine to detect high-grade cervical precancer (cervical intraepithelial neoplasia grade 2+ [CIN2+]) using two urine collection devices. DESIGN: Randomised controlled trial. SETTING: St Mary's Hospital, Manchester, UK. POPULATION: Colposcopy attendees with abnormal cervical screening; a total of 480 participants were randomised. Matched urine and cervical samples were available for 235 and 230 participants using a first-void urine (FVU)-collection device and standard pot, respectively. METHODS: Urine was self-collected and mixed with preservative - randomised 1:1 to FVU-collection device (Novosanis Colli-pee® 10 mL with urine conservation medium [UCM]) or standard pot. Matched clinician-collected cervical samples were taken before colposcopy. HPV testing used Roche cobas® 8800. A questionnaire evaluated urine self-sampling acceptability. MAIN OUTCOME MEASURES: The primary outcome measured sensitivity of HPV-tested urine (FVU-collection device and standard pot) for CIN2+ detection. Secondary outcomes compared HPV-tested cervical and urine samples for CIN2+ and evaluated the acceptability of urine self-sampling. RESULTS: Urine HPV test sensitivity for CIN2+ was higher with the FVU-collection device (90.3%, 95% CI 83.7%-94.9%, 112/124) than the standard pot (73.4%, 95% CI 64.7%-80.9%, 91/124, p = 0.0005). The relative sensitivity of FVU-device-collected urine was 0.92 (95% CI 0.87-0.97, pMcN = 0.004) compared with cervical, considering that all women were referred after a positive cervical HPV test. Urine-based sampling was acceptable to colposcopy attendees. CONCLUSIONS: Testing of FVU-device-collected urine for HPV was superior to standard-pot-collected urine in colposcopy attendees and has promising sensitivity for CIN2+ detection. General population HPV testing of FVU-device-collected urine will establish its clinical performance and acceptability as an alternative to routine cervical screening.

ABSTRACT

INTRODUCTION: Despite breakthroughs in cervical cancer detection, resource-constrained countries continue to have a disproportionately high incidence and death rate. Mhealth has been identified as an important tool for increasing cervical cancer screening rates in Sub-Saharan Africa. We determined whether sending Ghanaian women culturally tailored one-way mobile phone SMS text messages about cervical cancer would encourage the uptake of the human papillomavirus (HPV) test. METHODS: From August to November 2016, 88 women aged 18 to 39 living or working in an urban community (Accra, Ghana) participated in a quasi-experimental study. For 8 weeks, 32 SMS messages regarding cervical cancer were developed and sent to the personal phones of intervention arm participants (n = 42). Women in the control group (n = 46) received SMS texts with general health and lifestyle advice. Fischer's exact tests were performed to assess cervical cancer screening uptake and associated reasons for non-uptake between the intervention and control groups (p < 0.05). RESULTS: At the baseline, women differed in terms of ethnicity and wealth. After the intervention, participants' self-reported risk factors for cervical cancer, such as early menarche, usual source of medical treatment, family history of cancer, smoking, and alcohol history, changed. None of the women in the intervention group sought cervical cancer screening after the intervention, but only one (2.2%) of the control arm participants did. Almost all the women (> 95%) agreed that an HPV test was essential and that regular healthcare check-ups could help prevent cervical cancer. Some women believed that avoiding particular foods could help prevent cervical cancer (23.8% intervention vs. 58.7% control, p < 0.001). Time constraints and out-of-pocket expenses were significant barriers to cervical cancer screening. CONCLUSION: A one-way SMS delivered to urban women did not increase cervical cancer screening attendance. The time spent in screening facilities and the lack of coverage by the National Health Insurance Scheme limited screening uptake. We urge for the establishment of screening centers in all healthcare facilities, as well as the inclusion of cervical cancer screening in healthcare programs through cost-sharing.

ABSTRACT

BACKGROUND: We assessed experiences of human papillomavirus (HPV) vaginal self-sampling and future screening preferences in an ethnically and socio-economically diverse group of women overdue for cervical screening. SETTING AND PARTICIPANTS: A postal questionnaire was embedded in the YouScreen self-sampling trial in England: 32.5% (2712/8338) of kit completers returned the survey. Kit non-completers were encouraged to return a questionnaire, but no responses were received. Participants were ethnically diverse (40.3% came from ethnic minority backgrounds), and 59.1% came from the two most deprived quintiles. Differences in confidence in kit completion, trust in the test results and intention to attend a follow-up test if HPV-positive were evaluated using Pearson's χ2 analyses. Binary logistic regression models explored predictors of a future screening choice and preferences for urine versus vaginal self-sampling. RESULTS: Most kit-completers reported high confidence in self-sampling (82.6%) and high trust in the results (79.9%), but experiences varied by ethnicity and screening status. Most free-text comments were positive but some reported difficulties using the device, pain or discomfort. Most women would opt for self-sampling in the future (71.3% vs. 10.4% for a clinician-taken test) and it was more often preferred by ethnic minority groups, overdue screeners and never attenders. Urine self-tests were preferred to vaginal tests (41.9% vs. 15.4%), especially among women from Asian, Black or Other Ethnic backgrounds. CONCLUSIONS: Kit-completers were confident, found the test easy to complete, and trusted the self-sample results. However, experiences varied by ethnic group and some women highlighted difficulties with the kit. Most women would prefer self-sampling in the future, but it was not a universal preference, so offering a choice will be important. PATIENT OR PUBLIC CONTRIBUTION: We did not have direct patient and public involvement and engagement (PPIE) in the questionnaire design. However, patients and public representatives did input into the design of the YouScreen trial and reviewed the wider study materials (e.g. participant information sheet). TRIAL REGISTRATION: This questionnaire study was embedded in the YouScreen trial. The protocol for the YouScreen trial is available at https://www.isrctn.com/ISRCTN12759467. The National Institute for Health Research 43 Clinical Research Network (NIHR CRN) Central Portfolio Management System (CPMS) ID is 4441934.

ABSTRACT

BACKGROUND: In July 2022, self-collection became universally available as part of Australia's National Cervical Screening Program. This change aims to address screening inequities experienced among underscreened populations, including women of Indian descent. This study explored experiences of cervical screening, alongside the acceptability of self-collection, among women of Indian descent living in Victoria, Australia. We also aimed to articulate the informational needs to promote self-collection among this population. METHODS: Five focus group discussions with 39 women living in Victoria were conducted in English (n = 3) and Punjabi (n = 2). Transcripts were thematically analysed, as informed by the Theoretical Framework of Acceptability. RESULTS: Women were motivated by the choice to self-collect, perceiving the ability to maintain modesty and greater autonomy as key enablers. Healthcare practitioners were seen as central in supporting patient-centred models of care. Perceived barriers to self-collection included concerns around its accuracy and women's confidence in collecting their own sample. Widespread dissemination of culturally tailored promotion strategies communicating concepts such as 'privacy' and 'accuracy' were suggested by women to promote self-collection. CONCLUSION: Self-collection was highly acceptable among women of Indian descent, particularly when assured of its accuracy, and sociocultural norms and previous screening experiences are considered. This study highlights the huge potential that self-collection can play in increasing equity in Australia's cervical screening programme. PATIENT OR PUBLIC CONTRIBUTION: Members of the public were involved in focus group discussions. Findings were summarised and disseminated via a poster. A bicultural worker was involved in all stages of the research.

ABSTRACT

BACKGROUND: Cervical cancer is a global disease and it is well established that cervical cancer is caused by human papillomavirus (HPV). In Sweden self-sampling for HPV is now used as a complement to sampling performed by a midwife. However, there is a lack of knowledge on how older women perceive the self-sampling compared to the sampling performed by a midwife. Therefore, the aim of the study was to describe how women, aged 64 years and older, perceived the process of self-sampling and sampling performed by a midwife for HPV-testing. METHODS: Eighteen women were included in a qualitative interview study, and a phenomenographic approach was used for the analysis of the interviews. RESULTS: Three descriptive categories emerged: Confidence in sampling, Facilitating participation and Being informed. Within the categories, eight conceptions emerged describing the variation relating to how the women perceived the process of self-sampling and sampling performed by a midwife. CONCLUSIONS: Women in this study describe confidence in self-sampling for HPV-testing and that the self-sampling was saving time and money, both for themselves and for society. Information in relation to an HPV-positive test result is of importance and it must be kept in mind that women affected by HPV may feel guilt and shame, which health care professionals should pay attention to. This knowledge can be used in education of health care staff. TRIAL REGISTRATION: https://researchweb.org/is/fourol/project/228071 . Reg. no 228,071.

ABSTRACT

The aim of this study was to explore perceptions of members of the public and key stakeholders of a localised campaign to increase engagement with cervical cancer screening. Whilst numerous interventions have been trialled to increase engagement with cancer screening, the evidence for their effectiveness is somewhat mixed. In addition, few studies have explored the perceptions of members of the public targeted by such campaigns nor the perceptions of healthcare professionals who may be involved in delivering such campaigns in the United Kingdom. Members of the public who had potentially been exposed to the campaign in the North-East of England were approached to take part in individual interviews whilst stakeholders were invited to take part in a focus group. A total of 25 participants (13 members of the public, 12 stakeholders) took part. All interviews were audio recorded, transcribed verbatim and analysed using applied thematic analysis. Four themes were identified, two of which were cross-cutting (barriers to screening and factors promoting screening), with one theme identified as specific to the public interviews (knowledge of and attitudes toward awareness campaigns) and one theme specific to the focus group (keeping campaigns relevant. Awareness of the localised campaign was limited; however, when made aware, participants were mostly positive towards the approach, although mixed responses were noted in relation to financial incentives. Members of the public and stakeholders identified some common barriers to screening although differed in their perceptions of promotional factors. This study highlights the importance of multiple strategies to promote cervical screening as one size fits all approach may limit engagement.

ABSTRACT

ISSUE ADDRESSED: Cervical screening rates for young women aged between 25 and 35 are lower than older Australian women, however, little research has been conducted to understand why. This study aimed to identify and explore the barriers and enablers faced by young Victorians with a cervix to regular cervical screening. METHODS: This study used a mixed method exploratory design consisting of qualitative focus groups and a quantitative online survey. Four focus groups were conducted with 24 Victorians with a cervix aged between 25 and 35. Barriers, enablers and knowledge of cervical screening were explored. Focus groups were recorded and transcribed for thematic analysis of common themes. A supporting online survey was completed by 98 respondents. Summary statistics were analysed for differences in age. RESULTS: Focus groups and the online survey revealed four main factors that influence young people's cervical screening behaviour. These include past negative screening experiences, practitioner factors, priority placed on cervical screening, and cervical screening knowledge. These factors differ to the opinions of people older than 35, with young people focusing more on the psychological elements of cervical screening compared with practical factors. CONCLUSIONS: This research provides a unique insight into cervical screening barriers faced by women and people with a cervix aged between 25 and 35 as well as what factors motivate them to screen. SO WHAT?: These findings should be utilised to inform the design of public health campaign messaging targeting this age demographic. Findings can also assist practitioners to improve how they communicate with young people in a clinical setting.

ABSTRACT

In Australia's HPV-based cervical screening program, we previously showed that risk of histological high-grade abnormality at 1 year post screening decreased with age in women with oncogenic HPV. In this study, we followed 878 HPV16/18 positive women aged 55 years and over for up to 3 years post screening test, to determine the proportion with histological high-grade abnormality (HGA, incorporating high-grade squamous intraepithelial abnormality (HSIL), adenocarcinoma in situ (AIS), squamous cell carcinoma (SCC) and adenocarcinoma) and to correlate risk of HGA with liquid-based cytology result and with prior screening history. HGA was detected in 7.8% at 1 year and 10.0% at 3 years, with no significant difference (P = .136), despite the number of women with follow-up information significantly increasing from 82.9% to 91.0% (P < .0001). The proportion of HPV16/18 positive women with HGA at 3 years was highest in those with an HSIL cytology result (79.0%) and lowest in those with negative cytology (6.2%). Women with an adequate screening history had fewer HGA than such women with inadequate prior screening (6.6% vs 16.0%, P = .001) or with a history of an abnormality (6.6% vs 14.4%, P = .001). HPV16/18 infection in women over 55 years may have a different natural history from that in younger women, in whom HGA are more common after HPV16/18 detection. In HPV-based cervical screening programs, management algorithms for screen-detected abnormalities based on risk stratification should include factors such as age, screening history and index cytology result, so that women receive appropriate investigation and follow-up.

ABSTRACT

Human papillomavirus (HPV) testing for cervical screening increases diagnosis of precancer and reduces the incidence of cervical cancer more than cytology alone. However, real-world evidence from diverse practice settings is lacking for the United States (U.S.) to support clinician adoption of primary HPV screening. Using a population-based registry, which captures all cervical cytology (with or without HPV testing) and all cervical biopsies, we conducted a real-world evidence study of screening in women aged 30 to 64 years across the entire state of New Mexico. Negative cytology was used to distinguish cotests from reflex HPV tests. A total of 264 198 cervical screening tests (with exclusions based on clinical history) were recorded as the first screening test between 2014 and 2017. Diagnoses of cervical intraepithelial neoplasia grades 2 or 3 or greater (CIN2+, CIN3+) from 2014 to 2019 were the main outcomes. Of cytology-negative screens, 165 595 (67.1%) were cotests and 4.8% of these led to biopsy within 2 years vs 3.2% in the cytology-only group. Among cytology-negative, HPV tested women, 347 of 398 (87.2%) CIN2+ cases were diagnosed in HPV-positive women, as were 147 of 164 (89.6%) CIN3+ cases. Only 29/921 (3.2%) CIN3+ and 67/1964 (3.4%) CIN2+ cases were diagnosed in HPV-negative, cytology-positive women with biopsies. Under U.S. opportunistic screening, across a diversity of health care delivery practices, and in a population suffering multiple disparities, we show adding HPV testing to cytology substantially increased the yield of CIN2+ and CIN3+. CIN3+ was rarely diagnosed in HPV-negative women with abnormal cytology, supporting U.S. primary HPV-only screening.

ABSTRACT

BACKGROUND: Cervical cancer is one of the most common malignancies affecting women worldwide with large geographic variations in prevalence and mortality rates. It is one of the leading causes of cancer-related deaths in Ethiopia, where vaccination and screening are less implemented. However, there is a scarcity of literature in the field. Therefore, the objective of this review was to describe current developments in cervical cancer in the Ethiopian context. The main topics presented were the burden of cervical cancer, knowledge of women about the disease, the genotype distribution of Human papillomavirus (HPV), vaccination, and screening practices in Ethiopia. METHODS: Published literature in the English language on the above topics until May 2021 were retrieved from PubMed/Medline, SCOPUS, Google Scholar, and the Google database using relevant searching terms. Combinations of the following terms were considered to retrieve literature; < Cervical cancer, uterine cervical neoplasms, papillomavirus infections, papillomavirus vaccines, knowledge about cervical cancer, genotype distribution of HPV and Ethiopia > . The main findings were described thematically. RESULTS: Cervical cancer is the second most common and the second most deadly cancer in Ethiopia, The incidence and prevalence of the disease is increasing from time to time because of the growth and aging of the population, as well as an increasing prevalence of well-established risk factors. Knowledge and awareness about cervical cancer is quite poor among Ethiopian women. According to a recent report (2021), the prevalence of previous screening practices among Ethiopian women was at 14%. Although HPV 16 is constantly reported as the common genotype identified from different grade cervical lesions in Ethiopia, studies reported different HPV genotype distributions across the country. According to a recent finding, the most common HPV types identified from cervical lesions in the country were HPV-16, HPV-52, HPV-35, HPV-18, and HPV-56. Ethiopia started vaccinating school girls using Gardasil-4™ in 2018 although the coverage is insignificant. Recently emerging reports are in favor of gender-neutral vaccination strategies with moderate coverage that was found superior and would rapidly eradicate high-risk HPVs than vaccinating only girls. CONCLUSIONS: Cervical cancer continues to be a major public health problem affecting thousands of women in Ethiopia. As the disease is purely preventable, classic cervical cancer prevention strategies that include HPV vaccination using a broad genotype coverage, screening using a high precision test, and treating cervical precancerous lesions in the earliest possible time could prevent most cervical cancer cases in Ethiopia. The provision of a focused health education supported by educational materials would increase the knowledge of women about cervical cancer in general and the uptake of cervical cancer prevention and screening services in particular.

ABSTRACT

OBJECTIVES: To assess sexual behaviour, and sexual and reproductive health (SRH) outcomes, after 1 year of the COVID-19 pandemic in Britain. METHODS: 6658 participants aged 18-59 and resident in Britain completed a cross-sectional web-panel survey (Natsal-COVID-Wave 2, March-April 2021), 1 year after the first lockdown. Natsal-COVID-2 follows the Natsal-COVID-Wave 1 survey (July-August 2020) which captured impacts in the initial months. Quota-based sampling and weighting resulted in a quasi-representative population sample. Data were contextualised with reference to the most recent probability sample population data (Natsal-3; collected 2010-12; 15 162 participants aged 16-74) and national surveillance data on recorded sexually transmitted infection (STI) testing, conceptions, and abortions in England/Wales (2010-2020). The main outcomes were: sexual behaviour; SRH service use; pregnancy, abortion and fertility management; sexual dissatisfaction, distress and difficulties. RESULTS: In the year from the first lockdown, over two-thirds of participants reported one or more sexual partners (women 71.8%; men 69.9%), while fewer than 20.0% reported a new partner (women 10.4%; men 16.8%). Median occasions of sex per month was two. Compared with 2010-12 (Natsal-3), we found less sexual risk behaviour (lower reporting of multiple partners, new partners, and new condomless partners), including among younger participants and those reporting same-sex behaviour. One in 10 women reported a pregnancy; pregnancies were fewer than in 2010-12 and less likely to be scored as unplanned. 19.3% of women and 22.8% of men were distressed or worried about their sex life, significantly more than in 2010-12. Compared with surveillance trends from 2010 to 2019, we found lower than expected use of STI-related services and HIV testing, lower levels of chlamydia testing, and fewer conceptions and abortions. CONCLUSIONS: Our findings are consistent with significant changes in sexual behaviour, SRH, and service uptake in the year following the first lockdown in Britain. These data are foundational to SRH recovery and policy planning.

ABSTRACT

Cervical screening is increasingly switching to human papillomavirus (HPV) testing. In many settings, the switch has involved one or several co-tests (testing using both cytology and HPV) in the screening guidelines, to ensure safety. When Sweden switched to HPV testing in 2015 the guidelines included a co-test at age 41. To evaluate the effect of co-testing, we identified all 208,701 women resident in Sweden who in 2019 were 40-42 years old and thus eligible for co-testing. All cervical samples, the results of the test and of the subsequent biopsies were identified in the Swedish National Cervical Screening Registry. Out of the 10,643 women with co-testing in screening, there were 197 women with a subsequent biopsy with high-grade cervical neoplasia or worse (CIN2+). Among these 197 women, 189 had a screening test positive for both HPV and cytology, 6 women were HPV+/Cyt- and 2 women were HPV-/Cyt+. There were 7115 women with a co-test outside of the screening program. Among these, 325 women had a CIN2+ in histopathology, 290 were double positive, 13 women were cyt+/HPV-, and 11 women each were HPV+/cyt- and HPV-/Cyt-. In summary, the additional yield of CIN2+ with co-testing was 2 cases per 10,643 women as compared with 195/10,643 CIN2+ cases detected with HPV screening alone. However, for cervical samples taken outside the screening program (e.g. taken on a clinical indication) there was an increased yield (314 CIN2+ cases detected with co-testing as compared to 301 cases with HPV screening).

ABSTRACT

OBJECTIVE: To understand the effect of changing from cytology-based to primary HPV screening on the positive predictive value (PPV) of colposcopy referrals for cervical intraepithelial neoplasia (CIN) in a cohort offered HPV vaccination. DESIGN: Retrospective pre/post observational cohort study. SETTING: Scotland. POPULATION OR SAMPLE: 2193 women referred to colposcopy between September 2019 and February 2020 from cytology-based screening and between September 2020 and February 2021 from primary high-risk HPV (hrHPV) screening. METHODS: Calculating positive predictive values (PPVs) for two cohorts of women; one having liquid-based cytology screening and the other, the subsequent hrHPV cervical screening as a pre/post observational study. MAIN OUTCOME MEASURES: Positive predictive values of LBC and hrHPV cut-offs for colposcopy referral for CIN at colposcopy. RESULTS: Three papers fitted our criteria; these reported results only for cytology-based screening. The PPV was lower for women in HPV-vaccinated cohorts indicating a lower prevalence of disease. Vaccination under the age of 17 had the lowest PPV reported. Scottish colposcopy data concerning hrHPV and cytology showed a non-significant difference between PPV (17.5%, 95% CI 14.3-20.7, and 20.6, 95% CI 16.7-24.5, respectively) for referrals with a cut-off of low grade dyskaryosis (LGD); both met the standard set of 8-25%. The hrHPV PPV (66.7, 95% CI 56.8-76.6) was comparable to cytology (64.1, 95% CI 55.8-72.4) for referrals with a cut-off of high grade dyskaryosis (HGD) but neither met the standard set of 77-92%. CONCLUSIONS: Current literature only provides PPVs for LBC and, overall, the vaccinated cohort had lower PPVs. Only LG dyskaryosis met PHE criteria. The PPV for HPV-vaccinated women undergoing either LBC or HR-HPV screening were not statistically different. However, similar to papers in the current literature, HG dyskaryosis (HGD) PPVs of both techniques did not meet the PHE threshold of 76.6-91.6% outlined in the cervical standards data report.

ABSTRACT

BACKGROUND: Cervical cancer is almost entirely preventable with appropriate and timely screening. In Ontario, Canada, South Asian, Middle Eastern and North African women have some of the lowest rates of screening and a suggested higher burden of cervical cancer. With increasing international evidence and adoption of HPV testing, many screening programs are making the move away from Pap tests and towards HPV testing with the option of HPV self-sampling seeming promising for under- or never-screened (UNS) women. Our study aimed to understand the uptake and acceptability of an HPV self-sampling intervention amongst these disproportionately UNS women in Peel region and surrounding areas in Ontario. METHODS: A community -based mixed methods approach guided by the RE-AIM framework was used to recruit approximately 100 UNS racialized immigrant women aged 30-69, during the period of June 2018 to December 2019. The main recruitment strategy included community champions (i.e. trusted female members of communities) to engage people in our selected areas in Peel Region. Participants completed a study questionnaire about their knowledge, attitudes and practices around cervical cancer screening, self-selected whether to use the HPV self-sampling device and completed follow-up questions either about their experience with self-sampling or going to get a Pap test. RESULTS: In total, 108 women participated in the study, with 69 opting to do self-sampling and 39 not. The majority of women followed through and used the device (n = 61) and found it 'user friendly.' The experience of some participants suggests that clearer instructions and/or more support once at home is needed. Survey and follow-up data suggest that privacy and comfort are common barriers for UNS women, and that self-sampling begins to address these concerns. Across both groups addressing misinformation and misconceptions is needed to convince some UNS women to be screened. Family, friends and peers also seemed to play a role in the decision-making process. CONCLUSIONS: HPV self-sampling is viewed as an acceptable alternative to a Pap test for cervical screening, by some but not all UNS women. This method begins to address some of the barriers that often prevent women from being screened and is already being offered in some jurisdictions as an alternative to clinical cervical cancer screening.

ABSTRACT

INTRODUCTION: Human papillomavirus (HPV) testing is transforming cervical screening globally. The World Health Organization (WHO) now recommends same-day HPV screen-and-treat for primary cervical screening in low- and middle-income countries (LMIC) but there is a lack of evidence on women's lived experience of testing positive for oncogenic HPV and receiving same-day treatment. This study aimed to address this knowledge gap among women participating in a same-day HPV screen-and-treat (HPV S&T) program in Papua New Guinea. METHODS: As part of a larger qualitative study, this paper explores the lived experiences of 26 women who tested positive for oncogenic HPV and were treated the same day. We analysed the data using the interpretative phenomenological analysis method. All data were managed using Nvivo 12.5. RESULTS: The interpretative phenomenological analysis led to three superordinate themes: 1) facing and alleviating initial worries, (2) transforming the disclosure process, and (3) connecting to their faith. Women's experiences of the same day HPV screen-and-treat were framed by initial emotional reactions to their positive HPV test result, and having access to treatment on the same day, which helped address their worries and fears, and transformed their experience of disclosing their test result and subsequent treatment to family and friends. CONCLUSION: This study shows that, while women experience similar initial emotional reactions, undergoing same day treatment quickly resolved the women's worries, making this program highly acceptable. Overall, women's engagement in the program confirmed its high acceptability and cultural congruence, leaving women feeling empowered and hopeful about their future, and the future of all Papua New Guinea women.
