RESUMEN

Cervical cancer is currently the second leading cause of cancer death among women in Ghana. Previous studies have identified lack of awareness, lack of perceived susceptibility, and stigmatizing beliefs as significant sociocultural barriers to cervical cancer screening among Ghanaian women. The purpose of this study was to assess the acceptability of evidence and theory-based, culturally relevant cervical cancer education intervention materials among Ghanaian healthcare providers. Central-location intercept questionnaires were completed by providers (n = 60) in the Greater Accra region of Ghana. Providers reviewed a poster, an audio message, and a brief educational video. The variables assessed included the reaction to the materials, the ability of the materials to attract the attention of the intended audience, the ability of the materials to communicate the main point of the cancer education message, and the reaction to cultural characteristics of the materials. The mean age of the providers (n = 60) was 30.6 years, and the majority (70.8%) were females. Most of the providers had a positive general reaction to the poster, audio message, and video. The majority found the materials to be motivating. Most of the providers found the information in the materials to be attention-getting, interesting, useful, direct/to the point, and related to someone like them. Very few providers (5%) indicated that they were confused by the images or messages used in the materials. The culturally relevant cervical cancer education materials were acceptable to Ghanaian healthcare providers. These materials may be effective in shared decision-making for cervical cancer screening.

RESUMEN

The effect of cancer in women has varied effects. Overall malignancies of the breast, cervix, and ovary account for over 43% of all cancer cases in India. Globally, cervical cancer is fourth cancer in terms of incidence among women, following breast, lung, and colorectal cancer. However, this illness primarily affects women in India, where it is the second most frequent malignancy after breast cancer. HPV-related cervical cancer is a serious public health issue that has a solution. In 2020, the World Health Organization (WHO) launched a global initiative to eliminate cervical cancer which set targets for three important strategies: HPV vaccination, cervical cancer screening, and treatment. The WHO's "Best Buys" recommendations for cancer sub-set place vaccination of females between the ages of 9 and 14 at the top of the list. In India, efforts are underway to increase the number of teenage girls receiving the human papillomavirus (HPV) vaccine. The nation granted licenses for bivalent and quadrivalent HPV vaccinations in 2008, and in 2018, a nonavalent vaccine was approved. It is important to keep in mind that the cervical carcinoma vaccination is not a quick fix; thus, screening for the disease should continue. Any nation can potentially significantly lower the incidence of cervical cancer by carefully combining economical, high-coverage vaccinations with well-organized screening programs. Since 9-14 years is the ideal age range before sexual debut in today's world, this is the key vaccine age range. Estimates of vaccine effectiveness for younger adolescents, those between the ages of 9 and 14 years, varied from roughly 74 to 93%. Let us envision an India of the future where girls grow up with one fewer cancer threatening their life and a place where cervical cancer has been eradicated.

RESUMEN

Background: Human papillomavirus (HPV) vaccination during the postpartum period is an opportunity for vaccine eligible individuals to be vaccinated. Objective: Identify predictors of vaccine acceptance in the postpartum period among patients aged 18-26. Study Design: A retrospective chart review was conducted to evaluate the rate of HPV vaccination to eligible postpartum patients aged 18-26 who delivered between January 2021 and May 2023 at our institution. Clinical and demographic data were extracted. Comparisons were made between fully vaccinated individuals and those who were unvaccinated or incompletely vaccinated. Variables significantly associated with vaccination status or acceptance were included in a multivariable logistic regression model. Results: Of the 1,130 patients who met the study inclusion criteria, 42.1% were eligible for postpartum HPV vaccination. The average age was 23 years, the majority White (74.5%), and English speaking (93.1%). Nineteen percent of eligible patients accepted HPV vaccination, with differences between those who accepted or declined the vaccine identified in: preferred language, tobacco use, delivering provider's specialty, and receiving any vaccination during pregnancy. Spanish-speaking patients had >5× the odds of accepting the vaccine compared with English-speaking patients. Smokers, patients delivered by a family medicine provider, and those who accepted any vaccine during pregnancy had more than twice the odds of receiving the vaccine postpartum. Conclusion(s): The postpartum period remains an opportunity to provide HPV vaccination. Our study identified patients less likely to be vaccinated prior to delivery, as well as patients who are more likely to accept vaccinations postpartum.

RESUMEN

INTRODUCTION: To eliminate cervical cancer (CC), access to and quality of prevention and care services must be monitored, particularly for women living with HIV (WLHIV). We assessed implementation practices in HIV clinics across sub-Saharan Africa (SSA) to identify gaps in the care cascade and used aggregated patient data to populate cascades for WLHIV attending HIV clinics. METHODS: Our facility-based survey was administered between November 2020 and July 2021 in 30 HIV clinics across SSA that participate in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. We performed a qualitative site-level assessment of CC prevention and care services and analysed data from routine care of WLHIV in SSA. RESULTS: Human papillomavirus (HPV) vaccination was offered in 33% of sites. Referral for CC diagnosis (42%) and treatment (70%) was common, but not free at about 50% of sites. Most sites had electronic health information systems (90%), but data to inform indicators to monitor global targets for CC elimination in WLHIV were not routinely collected in these sites. Data were collected routinely in only 36% of sites that offered HPV vaccination, 33% of sites that offered cervical screening and 20% of sites that offered pre-cancer and CC treatment. CONCLUSIONS: Though CC prevention and care services have long been available in some HIV clinics across SSA, patient and programme monitoring need to be improved. Countries should consider leveraging their existing health information systems and use monitoring tools provided by the World Health Organization to improve CC prevention programmes and access, and to track their progress towards the goal of eliminating CC.

RESUMEN

Background: Cervical cancer continues to be a major health issue in low- and middle-income countries (LMICs). Despite increasing access to screening, access to precancer treatment remains a significant challenge in LMICs, highlighting a need for innovative, accessible and resource-appropriate treatment approaches, including self-administered therapies. Methods: A cross-sectional mixed-methods study was conducted among men aged 25-65 with a current female partner in Kisumu County, Kenya. Participants were sequentially recruited and surveyed to evaluate their understanding of human papillomavirus and cervical cancer, their views on screening and treatment and their attitudes toward self-administered therapies. Focus group discussions (FGDs) with a subset of the survey participants further explored their treatment preferences and perceptions. Results: Two hundred fourteen men participated in the survey, and 39 men participated in FGDs. The median age was 39 years, and 51% had a primary school education or less. Most (96%) were in a committed relationship, and 74% earned $10 or less daily. There was strong support for self-administered topical therapies, with 98% willing to support their partners using such treatments if available. Additionally, most participants were open to supporting necessary abstinence or condom use, though 76% believed their partners might hesitate to request condom use. When given an option, most preferred their partner to self-administer such therapies at home compared to provider administration at a health facility, citing convenience, cost-effectiveness and privacy. Preferences varied between two potential therapies, 5-Fluorouracil and Artesunate, based on their administration frequency, duration and abstinence requirements. Qualitative findings largely supported the quantitative analysis. Conclusion: The study demonstrates strong support for self-administered topical therapies for cervical precancer among Kenyan men. Additional research on acceptability, feasibility and efficacy in different LMICs could pave the way for these therapies to help bridge current cervical precancer treatment gaps in these settings.

RESUMEN

Colposcopy constitutes a pivotal step in the diagnosis and management of cervical intraepithelial neoplasia; nevertheless, the method has several inherent and external limitations. Electrical impedance spectroscopic (EIS) has been among the adjuncts that have been developed to increase the diagnostic accuracy of colposcopy. EIS is based on the principle that the trajectory of electrical current alters depending on the consistency of the tissues. In the present study, we investigate the diagnostic accuracy and clinical utility of EIS by means of searching the available evidence. Our search yielded 17 articles during the period 2005-2023. Subsequently, we focused on the performance metrics of the included studies. The general concept is that EIS, in combination with colposcopy, is a method with increased sensitivity and specificity in detecting high-grade cervical intraepithelial neoplasia as compared to colposcopy alone. However, we documented a heterogeneous distribution of these and other metrics, including the positive predictive value, the negative predictive value, and the area under the receiver operating characteristic curve (AUC). Additionally, we located potential confounders that might hamper the measurements of EIS and, as such, warrant further investigation in future research. We conclude that future studies should be directed towards randomized multicentric trials, whereas the advent of artificial intelligence might improve the diagnostic accuracy of the method by helping incorporate a large amount of data.

RESUMEN

Introduction: Despite being almost entirely preventable, cervical cancer is the fourth most frequently diagnosed cancer among women worldwide. Cervical cancer incidence suggests missed opportunities for prevention. Geospatial analysis could strategically guide public health interventions. This study aimed to identify geographic clusters of cervical cancer incidence in Texas, a state with higher than national rates of cervical cancer incidence and mortality. Methods: In this population-based cross-sectional study, the authors analyzed incident cervical cancer data among Texas women aged 30-64 years, from 2014 to 2018. The authors conducted a purely spatial Poisson-based analysis function in SaTScan to examine geographic clusters of higher-than-expected proportions of cervical cancer incidence (i.e., hot spots) and adjusted for age. Results: A total of 5,060 women aged 30-64 years with incident cervical cancer diagnosis (mean age: 45.7 years, SD=9.6), including 1,840 (36.4%) Hispanic, 591 (11.7%) non-Hispanic Black, 2,397 (47.4%) non-Hispanic White, and 232 (4.6%) other races, were analyzed. Spatial scan analysis detected 7 significant hot spots of cervical cancer incidence. Hot spots were identified in the South Texas Plains (near Mexico border), Gulf Coast (Houston), Prairies and Lakes (North Texas), Panhandle Plains (Northwest Texas), and Piney Woods (Southeast Texas) regions of Texas. Hot spots, compared with the rest of Texas, had higher proportions of Hispanic population and individuals with socioeconomic disadvantages. Conclusions: This study found spatial variation in cervical cancer incidence in Texas. The hot spot areas can benefit from targeted, novel, scalable, and cost-effective interventions to increase human papillomavirus vaccination and screening and early detection and treatment of precancerous cervical lesions.

RESUMEN

BACKGROUND: Inequities in access to human papillomavirus (HPV) vaccine are becoming a growing critical issue globally. Few studies investigate the factors determining HPV vaccine uptake disparities when vaccine supply is constrained, especially in low- and middle-income countries. The aim of this study was to investigate inequities of HPV vaccination and related factors under the constrained vaccine supply in China. METHODS: A cross-sectional survey was conducted in a developed eastern coastal province and a developing western one in China between November and December 2022. Employing multistage stratified cluster random sampling, the study collected data from parents of children aged 9-14. Mixed-effects logistic regression models with school units as random effects were used for analysis. RESULTS: From 4,127 eligible parents (as vaccine decision makers for girls), 1,346 (32.6%) intended to vaccinate their daughters against HPV, of which 836 (62.1%) attempted to schedule a vaccination appointment. Only 16.4% succeeded in booking an appointment. More than half of the intended parents expected the imported 9-valent HPV vaccine. There were significant disparities in HPV vaccine awareness, intention, and vaccination behavior across educational, income, geographic, ethnic, gender, and health literacy levels. Vaccine awareness and intentions were higher among parents with higher socioeconomic status; however, girls from lower socioeconomic families were more likely to receive the HPV vaccine and had a higher domestically produced vaccination rate. Significant disparities exist in vaccination intentions and actual vaccination behaviors, primarily due to large supply constraints of the HPV vaccine. CONCLUSIONS: Sustained health education campaigns are needed to raise awareness of the HPV vaccine, improve health literacy, and decrease over-preference for the 9-valent HPV vaccine. A mother's HPV vaccination behavior was positively associated with increased intention and actual vaccination behavior for her daughter. This study advocates for complementary cervical cancer prevention programs targeting both mothers and daughters.

RESUMEN

INTRODUCTION: Colposcopy is an important part of the diagnostic work-up of women with an abnormal cervical screening test as it is used to guide the collection of biopsies. Although quality assurance has been used in the evaluation of screening programs, not much is known about quality indicators for the diagnostics and treatment of screen-positive women. Therefore, the European Federation for Colposcopy developed quality indicators aiming to support colposcopy practice across Europe. We performed a survey of colposcopy cases to determine if the quality indicators are understandable, relevant, and reproducible. MATERIAL AND METHODS: We conducted a survey among all members of the European Federation for Colposcopy Quality and Standards Group from November 2022 to March 2023. Members were asked to collect information on a total of 17 quality indicators for 50 women who had been newly referred for colposcopy due to an abnormal screening test between January 1, 2020 to December 31, 2021. Results were reported descriptively. RESULTS: We included data on 609 cases from 12 members across Europe. The majority of the quality indicators were either achieved or within reach of the agreed standard, often due to few countries with outlying data. One quality indicator had very low performance, although stratified results indicated that two countries had different clinical management of the patient type thereby skewing the results. In addition, discrepancies between the number of cases included in each quality indicator raised concerns regarding potential misunderstanding of the quality indicator and its objective. CONCLUSIONS: Quality indicators on colposcopy must be understandable to those collecting data, highlighting the importance of validating quality indicators before data collection.

RESUMEN

INTRODUCTION: The rates of cervical cancer screening in Cameroon are unknown and HPV vaccination coverage for age-appropriate youths is reported at 5%. OBJECTIVES: To implement the mother-child approach to cervical cancer prevention (cervical screening by HPV testing for mothers and HPV vaccination for daughters) in Meskine, Far North, Cameroon. METHODS: After the sensitization of the Meskine-Maroua region using education and a press-release by the Minister of Public Health, a 5-day mother-child campaign took place at Meskine Baptist Hospital. The Ampfire HPV Testing was free for 500 women and vaccination was free for age-appropriate children through the EPI program. Nurses trained in cervical cancer education conducted group teaching sessions prior to having each woman retrieve a personal sample. Self-collected samples were analyzed for HPV the same day. All women with positive tests were assessed using VIA-VILI and treated as appropriate for precancers. RESULTS: 505 women were screened, and 92 children vaccinated (34 boys and 58 girls). Of those screened, 401 (79.4%) were aged 30-49 years old; 415 (82%) married; 348 (69%) no education. Of the HPV positive cases (101): 9 (5.9%) were HPV 16, 11 (10.1%) HPV 18, 74 (73%) HPV of 13 other types. Those who were both HPV and VIA-VILI positive were treated by thermal ablation (63%) or LEEP (25%). CONCLUSION: The mother-child approach is an excellent method to maximize primary and secondary prevention against cervical cancer.

RESUMEN

Introduction: Women living with human immunodeficiency virus (WLHIV) face elevated risks of human papillomavirus (HPV) acquisition and cervical cancer (CC). Coverage of CC screening and treatment remains low in low-and-middle-income settings, reflecting resource challenges and loss to follow-up with current strategies. We estimated the health and economic impact of alternative scalable CC screening strategies in KwaZulu-Natal, South Africa, a region with high burden of CC and HIV. Methods: We parameterized a dynamic compartmental model of HPV and HIV transmission and CC natural history to KwaZulu-Natal. Over 100 years, we simulated the status quo of a multi-visit screening and treatment strategy with cytology and colposcopy triage (South African standard of care) and six single-visit comparator scenarios with varying: 1) screening strategy (HPV DNA testing alone, with genotyping, or with automated visual evaluation triage, a new high-performance technology), 2) screening frequency (once-per-lifetime for all women, or repeated every 5 years for WLHIV and twice for women without HIV), and 3) loss to follow-up for treatment. Using the Ministry of Health perspective, we estimated costs associated with HPV vaccination, screening, and pre-cancer, CC, and HIV treatment. We quantified CC cases, deaths, and disability-adjusted life-years (DALYs) averted for each scenario. We discounted costs (2022 US dollars) and outcomes at 3% annually and calculated incremental cost-effectiveness ratios (ICERs). Results: We projected 69,294 new CC cases and 43,950 CC-related deaths in the status quo scenario. HPV DNA testing achieved the greatest improvement in health outcomes, averting 9.4% of cases and 9.0% of deaths with one-time screening and 37.1% and 35.1%, respectively, with repeat screening. Compared to the cost of the status quo ($12.79 billion), repeat screening using HPV DNA genotyping had the greatest increase in costs. Repeat screening with HPV DNA testing was the most effective strategy below the willingness to pay threshold (ICER: $3,194/DALY averted). One-time screening with HPV DNA testing was also an efficient strategy (ICER: $1,398/DALY averted). Conclusions: Repeat single-visit screening with HPV DNA testing was the optimal strategy simulated. Single-visit strategies with increased frequency for WLHIV may be cost-effective in KwaZulu-Natal and similar settings with high HIV and HPV prevalence.

RESUMEN

BACKGROUND:  Infection with the human papillomavirus (HPV) is a necessary cause of cervical cancer and is one of the most prevalent sexually transmitted infections worldwide. Primary prevention strategies target reducing HPV acquisition through vaccination, limiting exposure (e.g. delayed sexual debut, barrier contraception) and health education focusing on sexual behaviour and tobacco use. METHODS:  The ImmunoVACCS study, conducted from 2019 to 2022 in two provinces in South Africa, examined sociodemographic characteristics, sexual practices, and knowledge of cervical cancer and the HPV vaccine among young female vaccine recipients. It encompassed participants from the previously conducted vaccine implementation trials, VACCS 1 and VACCS 2 (2011-2014). Recruitment involved telephonic contact with eligible potential participants. Data were collected through self-administered questionnaires. RESULTS:  One hundred and eleven participants took part in the current study (median age: 20 years; age range: 16-22 years). Most sexually active participants had their first engagement in secondary school (96.2%), and 77.2% used contraception during their last sexual activity. Knowledge gaps were evident, with only 13.5% recognising cervical cancer's cervix origin and 3.6% attributing it to a virus. Despite this, 70.3% had heard of a vaccine for cervical cancer. Less than half knew about the importance of regular Pap smears (49.5%), vaccine protection (44.1%) or condom use (20.7%) against HPV and cervical cancer. CONCLUSION:  The current study demonstrates that young women still lack complete information on cervical cancer and its risk factors even after receiving health education linked with vaccination.Contribution: This study underscores the necessity of ongoing education about HPV, its risks and preventive measures among young women to combat cervical cancer.

RESUMEN

Human papillomavirus (HPV) is associated with cellular changes in the cervix leading to cancer, which highlights the importance of vaccination in preventing HPV infections and subsequent cellular changes. Women undergoing the loop electrosurgical excision procedure (LEEP), a treatment for high-grade cervical intraepithelial neoplasia (CIN2+), remain at risk of recurrence. This study assessed the effect of post-conization HPV vaccination on the viral status of women at six months post-conization, aiming to evaluate the vaccine's effectiveness in preventing recurrence of CIN2+. A retrospective cohort study was conducted among women in Troms and Finnmark who underwent conization in 2022. Using the SymPathy database and the national vaccination register (SYSVAK), we analyzed the vaccination statuses and HPV test results of women born before 1991, who had not received the HPV vaccine prior to conization. Out of 419 women undergoing conization, 243 met the inclusion criteria. A significant association was found between post-conization HPV vaccination and a negative HPV test at six months of follow-up (ARR = 12.1%, p = 0.039). Post-conization HPV vaccination significantly reduced the risk of a positive HPV test at the first follow-up, suggesting its potential in preventing the recurrence of high-grade cellular changes. However, the retrospective design and the insufficient control of confounding variables in this study underscore the need for further studies to confirm these findings.

RESUMEN

BACKGROUND: Cervical cancer poses a significant burden, particularly in low-and-middle income countries (LMIC) with limited access to healthcare. High-income countries have made progress in prevention, while LMIC face unacceptably high incidence and mortality rates, often lacking official screening recommendations. We analysed the presence and content of cervical cancer screening guidelines for the secondary prevention of cervical cancer in the Southern African Development Community (SADC) and compared it to the current World Health Organization (WHO) guidelines for screening and treatment of cervical pre-cancer lesions for cervical cancer prevention. METHODS: A review of national cervical cancer guidelines across the SADC region was conducted. Data was obtained from government websites, international cancer control platforms, and WHO resources. Search terms included "cervical cancer" and "cervical cancer control guidelines", amongst others. There were no limitations on publication years, and the most recent versions of the guidelines were analysed, regardless of language. Each guideline was assessed for specific screening and treatment recommendations, in relation to the current WHO guidelines. Points were assigned for each data element. RESULTS: While most countries contributed data to this analysis there was a notable absence of adherence to the WHO guidelines. The most common screening method was naked eye visual inspection. There was a consensus on the age of screening initiation. Most countries recommended treatment by cryotherapy and loop excision. CONCLUSION: Effective cervical cancer screening programmes, guided by evidence-based recommendations, can enhance early intervention and outcomes. This study highlights the need for standardized and evidence-based cervical cancer screening guidelines in the SADC region, to reduce the burden of cervical cancer and improve the health outcomes of women in these areas.

RESUMEN

BACKGROUND: Human papillomavirus (HPV), the most prevalent sexually transmitted infection globally, is a key risk factor for high-grade cervical lesions and cervical cancer. Since 2009, HPV vaccination has been part of the national immunization program for girls in 7th grade in Norway (women born 1997 and later). This study aimed to assess the impact of HPV vaccination on the incidence of high-grade cervical precursors (CIN2+) among women aged 20-25 in Troms and Finnmark over a 15-year period. MATERIALS AND METHODS: In this time series study, we analyzed cervical screening data from 15,328 women aged 20-25 in Troms and Finnmark, collected between 2008 and 2022. Statistical methods, including linear and logistic regression, were employed to evaluate changes in cervical intraepithelial neoplasia grade 2 and worse (CIN2+) incidence and compare risks between vaccine-offered cohorts and pre-vaccine cohorts. RESULTS: The incidence of CIN2+ initially increased from 31 cases per year in 2008 to 110 cases in 2018, then significantly decreased to 44 cases per year by 2022 (p < 0.01). Women in pre-vaccine cohorts had a substantially higher risk of CIN2+ (OR 9.02, 95% CI 5.9-13.8) and CIN3+ (OR 19.6, 95% CI 7.3-52.6). Notably, no vaccinated women with CIN2+ tested positive for HPV types 16 or 18. Furthermore, none of the 13 cervical cancer cases recorded during the study were from the vaccinated cohorts. INTERPRETATION: The findings suggest a significant reduction in the incidence of high-grade cervical precursors following the introduction of the HPV vaccine in Norway's national immunization program, highlighting its effectiveness in cervical cancer prevention among young women in Northern Norway.

RESUMEN

BACKGROUND: Human papillomavirus (HPV) vaccine is the most effective option for primary prevention HPV, a well-known cause of cervical cancer.  The objective of the study was to assess awareness of HPV, the acceptability of its vaccine and factors associated with the acceptability among the adult population in Pakistan. MATERIALS & METHODS: A cross-sectional survey was conducted among adult population of Pakistan from January 2022 and March 2022. Due to the ongoing COVID-19 pandemic, instead of face-to-face interviews, a self-administered questionnaire was developed and distributed through Google Forms. The questionnaire was available in both English and Urdu languages to cater to a diverse population. RESULTS: Overall, 313 (65.2 %) study participants had heard about HPV infection, while 297 (61.9%) knew HPV as the cause of genital warts and 256 (53.3 %) knew that HPV can cause any type of cancer, with a higher percentage of awareness among those who were in any health care setting compared to those who were in a non-healthcare setting. Regarding the acceptability to get HPV vaccine, 320 (66.7%) of the study participants were willing to get vaccinated, while only 15(3.1%) of the study population had previously received HPV vaccine. The most important factors associated with HPV vaccine acceptability were younger age of 18-25 years (Prevalence Ratio (PR) =1.60, 95% Confidence Interval (CI) =1.11, 2.32), and 26-35 years (PR= 1.65, 95% CI=1.09, 2.50). HPV vaccine acceptability was also associated with working in a healthcare setting due to better awareness of HPV vaccine (PR= 1.29, 95% CI=1.03, 1.62). CONCLUSION: It is important to address the knowledge gaps existing in the community about HPV vaccine acceptability and barriers against it for the successful rollout of the HPV vaccination program in Pakistan. Mass awareness campaigns about HPV, HPV vaccine, and cervical cancer are needed to increase the acceptability of HPV vaccine among public at the time of reintroducing HPV vaccine.

RESUMEN

Purpose: Cervical cancer disproportionately impacts women in low- and middle-income countries (LMICs). The World Health Organization's (WHO) 90/70/90 strategy aims to eliminate cervical cancer by 2030 by increasing HPV vaccination coverage to 90%, screening 70% of eligible women, and effectively treating 90% of those with abnormal results by 2030, potentially preventing 62 million deaths in LMICs. LMICs, however, struggle with limited access to cervical precancer treatment, in part due to a lack of trained professionals and weak health systems. Effective non-surgical, self-administered, which have demonstrated efficacy in high-income countries, could bridge the treatment gap in LMICs and may be more scalable and cost-effective than provider-administered therapies. To inform feasibility studies in LMICs, data are needed on the role of male partners in influencing the acceptability and uptake of self-administered topical therapies, including their support of recommended abstinence and contraception guidelines associated with these therapies. Methods: Between November 2022 and April 2023, we conducted five focus group discussions (FGDs) with men aged 25 to 65 years in Kenya to explore their perspective and perceived support regarding their female partners using topical self-administered therapies for cervical precancer treatment. The FGDs were moderated by local qualitative research assistants and conducted in local languages, transcribed, coded, and analyzed using qualitative description. Results: Thirty-nine male participants meeting the eligibility criteria participated in five FGDs. The mean age of participants was 42.5 years. Most participants, 79.5%, had a female partner with a history of cervical precancer treatment, 5.1% did not, and 15.4% were unsure of their female partner's prior precancer treatment history. The study aimed to assess men's support of their female partners' use of topical therapies for treating cervical precancer. We find that male participants strongly express acceptance and willingness to support their wives or partners in using such therapies, if available. Reported supportive behavior included permitting the use of the therapies and support of maintaining abstinence during the recommended times. Additionally, participants desired male involvement in clinic and community-based education about topical therapies to facilitate widespread support. Conclusion: The use of self-administered topical therapies for cervical precancer treatment, if supported by efficacy studies in LMICs, may support achieving the WHO's 2030 goal of 90% treatment access. We find that with adequate education, men express overwhelming support of their female partner's use of topical therapies, including adherence to abstinence and contraception guidelines.

RESUMEN

This study assessed the accuracy of high-risk human papillomavirus testing of BD Onclarity HPV (Onclarity) assay on vaginal self-collected FLOQSwab versus cervical samples to ensure similar accuracy to detect cervical intraepithelial neoplasia. Testing was performed on two automated platforms, BD Viper LT and BD COR, to evaluate the effect of machine and using two vaginal self-samples to analyze the influence of collection, transport, and freezing-unfreezing on the results. A cervical sample and two self-samples were collected from 300 women. The first collected vaginal and the cervical sample were tested on BD Viper LT, and the second swab was frozen and subsequently tested on both automated systems. Test results on vaginal and cervical specimens were considered the index and comparator, respectively; colposcopy and histology were reference standards. Relative sensitivity for ≥CIN2 on vaginal samples analyzed versus the cervical sample was 1.01 (0.97-1.06), 1.01 (0.97-1.06), and 1.00 (0.95-1.05), for the first, second self-collected sample tested on BD VIPER LT, and second self-collected sample tested on BD COR, respectively. Relative specificity was 0.83 (0.73-0.94), 0.76 (0.67-0.87), and 0.82 (0.73-0.92) using the three different workflows. Cut-off optimization for human papillomavirus (HPV) positivity defined at Ct ≤38.3 for HPV16, ≤ 34.2 for HPV18, and ≤31.5 for all other types showed an increased relative specificity with similar sensitivity. No significant difference was observed between self-samples tested with the two platforms and between first- and second-collected swabs. Onclarity assay on FLOQSwab using both platforms showed similar sensitivity but lower specificity to detect ≥CIN2 compared to cervical samples. By cut-off optimization, non-inferior specificity could be reached. IMPORTANCE: Human papillomavirus (HPV) testing on self-collected vaginal samples has been shown to improve women's participation to cervical cancer screening programs, particularly in regions with limited access to health care. Nevertheless, the introduction of self-sampling in cervical cancer screening programs requires prior clinical validation of the HPV assay in combination with a self-sample collection device, including also the laboratory workflow and automation required for high-throughput testing in screening. In this study, the performance of BD Onclarity HPV on FLOQSwab-collected vaginal self-samples has been compared to clinician-taken liquid-based cytology samples, to detect high-grade cervical intraepithelial neoplasia using two high-throughput platforms, BD Viper LT and BD COR. The study findings have shown a similar performance of BD Onclarity on testing self-collected samples, confirming the validation of the proposed pre-analytical and analytical protocols for their use in cervical cancer screening programs based on self-collected vaginal samples.

RESUMEN

INTRODUCTION/OBJECTIVES: With growing vaccination misinformation and mistrust, strategies to improve vaccination communication across community-based settings are needed. METHODS: The Rural Adolescent Vaccine Enterprise (RAVE), a 5-year (2018-2022) stepped-wedge cluster randomized study, tested a clinic-based practice facilitation intervention designed to improve HPV vaccination. An exploratory aim sought to explore the use of partnerships between primary care clinics and a community partner of their choosing, to implement a social marketing campaign related to HPV immunization. We assessed perceptions about the value and success of the partnership, and barriers and facilitators to its implementation using a 29-item community partner survey, key informant interviews, and field notes from practice facilitators. RESULTS: Of the initial 45 clinics participating in RAVE, 9 were unable to either start or complete the study, and 36 participants (80.0%) were actively engaged. Of these, 16/36 clinics (44.4%) reported establishing successful partnerships, 10 reported attempting to develop partnerships (27.8%), and another 10 reported not developing a partnership (27.8%), which were often caused by the COVID-19 pandemic. The most common partnership was with public health departments at 27.3%. Other partnerships involved libraries, school districts, and local businesses. More than half (63.7%) reported that creating messages regarding getting HPV vaccination was moderately to very challenging. Just under half reported (45.5%) that messaging was hard because of a lack of understanding about the seriousness of diseases caused by HPV, parents being against vaccines because of safety concerns, and religious values that result in a lack of openness to HPV vaccines. Community partners' health priorities changed as a result of RAVE, with 80% prioritizing childhood immunizations as a result of the RAVE partnership. CONCLUSIONS: Community groups want to partner with primary care organizations to serve their patients and populations. More research is needed on how best to bring these groups together.

RESUMEN

BACKGROUND: In recent years, active surveillance has been introduced as an alternative to excisional treatment in younger women with cervical intraepithelial neoplasia grade 2 because regression rates are high and excisional treatment is associated with increased risk of preterm birth. However, early identification of women at increased risk of persistence/progression is important to ensure timely treatment. Evidence is limited on biomarkers that may be used to identify women at increased risk of persistence/progression. OBJECTIVE: This study aimed to describe human papillomavirus HPV type-specific persistence/progression in women undergoing active surveillance for cervical intraepithelial neoplasia grade 2. STUDY DESIGN: We conducted a historical cohort study of women aged 23 to 40 years diagnosed with cervical intraepithelial neoplasia grade 2 at Aarhus University Hospital from 2000 to 2010. Women were identified through the Danish Pathology Data Bank (DPDB) and were considered as undergoing active surveillance if they had a first record of a cervical biopsy within 2 years after index diagnosis and no loop electrosurgical excision procedure before this. Human papillomavirus genotyping was performed on archived tissue samples using the HPV SPF10-DEIA-LiPA25 system (DNA ELISA [enzyme-linked immunosorbent assay] HPV SPF10 kit and RHA HPV SPF10-LiPA25 kit). Persistence/progression was defined as having a record of cervical intraepithelial neoplasia grade ≥2 in the DPDB determined on the last and worst diagnosis on a biopsy or loop electrosurgical excision procedure specimen during follow-up. We estimated the relative risk (95% confidence interval) of persistence/progression using a modified Poisson model. RESULTS: A total of 455 women were included. Two-thirds were aged ≤30 years (73.8%) at index diagnosis, and nearly half had a high-grade index cytology (48.8%). Overall, 52.2% of all women had cervical intraepithelial neoplasia grade ≥2 during follow-up; 70.5% were human papillomavirus-16-positive and 29.5% were positive for other human papillomavirus types. Human papillomavirus-16 was associated with a significantly higher risk of persistence/progression (relative risk, 1.64; 95% confidence interval, 1.37-1.95) compared with non-human papillomavirus-16. The risk of persistence/progression was highest in human papillomavirus-16-positive women with a high-grade index cytology compared with human papillomavirus-16-positive women with a low-grade cytology (relative risk, 1.29; 95% confidence interval, 1.03-1.61), whereas no differences were observed across age groups. CONCLUSION: The highest risk of persistence/progression was observed among human papillomavirus-16-positive women, particularly those with associated high-grade cytology. These findings suggest that early excisional treatment should be considered in this group of women.
