A systematic literature review of human papillomavirus vaccination strategies in delivery systems within national and regional immunization programs

The uptake of human papillomavirus (HPV) vaccine remains suboptimal despite being a part of routine vaccination within national immunization program(s). This indicates probable challenges with the implementation of HPV immunization program(s) in various countries. The objective of this systematic literature review (SLR) was to identify implementation strategies for HPV vaccination within national and regional immunization programs worldwide with an aim to provide guidance for countries targeting to increase their HPV vaccine coverage rate (VCR). A comprehensive literature search was conducted across Medline and Embase and included articles published between January 2012 and January 2022. Of the 2,549 articles retrieved, 168 met inclusion criteria and were included in the review. Strategies shown to improve HPV vaccination uptake in the reviewed literature include campaigns to increase community awareness and knowledge of HPV, health care provider trainings, integrating HPV vaccination within school settings, coordinated efforts via multi-sectoral partnerships, and vaccination reminder and recall systems. Findings may help national authorities understand key considerations for HPV vaccination when designing and implementing programs aiming to increase HPV VCR in adolescents.

Opportunities for HPV vaccine education in school-based immunization programs in British Columbia, Canada: A qualitative study

Despite the availability of school-based immunization programs (SBIPs) in Canada, human papillomavirus (HPV) vaccine uptake remains suboptimal. Vaccine education may improve vaccine uptake among adolescents. The objective of this qualitative study was to identify opportunities for HPV vaccine education in British Columbia, Canada, by exploring the perspectives of students, parents, school staff, and public health nurses on the current SBIP. Individual semi-structured interviews were conducted with adult participants and focus groups were conducted with grade 6 students between November 2019 and May 2020. The interviews and focus groups were transcribed and then analyzed using reflexive thematic analysis. Opportunities for HPV vaccine education were identified in three themes: 1) making SBIPs student-centered; 2) adopting a collaborative and interdisciplinary approach to vaccine education; and 3) actualizing parent education opportunities. Broad support existed for a formal, collaborative HPV grade 6 vaccine curriculum delivered by teachers and public health nurses to provide evidence-based health information. Participants voiced that the curriculum should integrate students' perspectives on topics of interest and address needle associated pain and anxiety. Parents were identified as the primary vaccine decisionmakers, therefore, participants stated it was crucial to also provide parent-directed vaccine education as part of SBIP. Our findings support the development of a collaborative HPV vaccine curriculum directed to and informed by students and parents to buttress current SBIPs in British Columbia.

High burden of human papillomavirus infection among men in Guangzhou, South China: Implications for HPV vaccination strategies

The epidemiological and clinical aspects of Human Papillomavirus (HPV) infection in women have been extensively studied. However, there is a lack of information regarding HPV characteristics in males. In this study, we conducted a retrospective and observational study of 3737 consecutive male individuals attending outpatient clinics of Guangdong Women and Children Hospital from 2012 to 2023 in Guangzhou, South China, to determine the age- and genotype-specific prevalence of HPV in men. The results showed the overall prevalence of HPV among men was 42.15% (1575/3737), with variations ranging from 29.55% to 81.31% across distinct diagnostic populations. Low-risk HPV6 (15.47%), HPV11 (8.94%), and high-risk HPV52 (5.51%) were the most common types. The annual HPV prevalence decreased significantly (Z = -3.882, p < .001), ranging from 31.44% to 52.90%. 28.77% (1075/3737) of men manifested infection with a singular HPV type, predominantly identified as a low-risk type. The age-specific distribution of HPV infections revealed distinctive peaks in the < 25 y age group (47.60%, 208/437) and the 40-44 y age group (44.51%, 154/346). Notably, the positive rate of Chlamydia trachomatis was significantly higher among HPV-positive individuals in comparison to HPV-negatives (16.14% vs. 11.25%, p < .05). Our findings reveal a substantial prevalence of HPV infection among outpatient men in Guangzhou, South China. It is recommended to consider the inclusion of HPV vaccination for adolescent males in national immunization schedules, once an adequate supply of vaccines is accessible.

Reduced risk of CIN2+ recurrence in women immunized with a 9-valent HPV vaccine post-excision: Retrospective cohort study

The main aim of our study was to investigate the specific contribution of a 9-valent human papillomavirus vaccine (9vHPV) to the recurrence risk of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) in women vaccinated post-excision. Therefore, we conducted a retrospective monocentric cohort study in women aged 22-49 years undergoing conization between 2014 and 2023. The 9vHPV-vaccinated women were matched to unvaccinated women for age and follow-up duration in a 1:2 ratio to eliminate allocation bias. The risk of CIN2+ recurrence was estimated by the incidence rate ratio using Poisson regression with adjustment for comorbidities, smoking status, nulliparity, CIN grade, positive cone margin, and HPV genotypes. The CIN2+ recurrence rates in 147 women enrolled in the analysis were 18 and 2 cases per 100,000 person-days for unvaccinated and vaccinated women, respectively, during a mean follow-up period of 30 months (±22 months). A reduction in CIN2+ recurrences by 90% (95% confidence interval: 12-99%) was documented in 9vHPV-vaccinated participants compared to women undergoing only surgical excision. Moreover, vaccinated women with a positive cone margin showed a 42% (though non-significant) reduction in relapse (p = .661). Full post-conization vaccination with the 9vHPV contributed to an additional reduction in the risk of CIN2+ recurrence. This finding is consistent with current knowledge and suggests a high adjuvant effect of the 9vHPV vaccine.

Detecting and genotyping high-risk human papillomavirus among male patients during 2015-2023 in Beijing, China

Few studies focused on human papillomavirus (HPV) in male patients. This study aimed to explore the detection rate and genotyping of HPV among male patients in Beijing to provide a reference for formulating prevention strategies for HPV infection. The cross-sectional study was conducted in Beijing Chaoyang Hospital from November 2015 to March 2023. It covered male patients from the urology and dermatology departments. Fifteen high-risk HPV genotypes were detected by the multiplex real-time polymerase chain reaction method. The overall detection rate of HPV was 25.19% (1288/5114, 95% confidence interval [CI] 24.00%-26.38%), of which the single infection rate was 16.99% (869/5114, 95% CI 15.97%-18.05%) and the co-infection rate was 8.19% (419/5114, 95% CI 7.46%-8.98%). The detection rate of HPV was 40.77% (521/1278), 35.58% (58/163), 32.69% (101/309), 31.91% (60/188), 12.63% (299/2367), and 32.35% (131/405) among male patients with balanitis, warts, rash, urethritis, prostatitis, and other urinary inflammation, respectively (P < 0.001). The top five HPV genotypes were HPV-52, HPV-58, HPV-16, HPV-51, and HPV-66. After the first positive HPV test, the proportion of male patients who turned negative was 22.47% within 3 months, 26.40% within 3-6 months, 24.72% within 6-12 months, 17.98% within 12-24 months, and 8.43% more than 24 months. The detection rate of HPV was high among male patients from the urology and dermatology departments in Beijing, which should be considered to develop HPV vaccines with better prevention effects.

Developing a narrative communication intervention in the context of HPV vaccination

Objective

We outline the development of a narrative intervention guided by the Common-Sense Model of Self-Regulation (CSM) to promote Human Papillomavirus (HPV) vaccination in a diverse college population.

Methods

We adapted the Obesity-Related Behavioral Intervention Trials (ORBIT) model to guide the development, evaluation, and refinement of a CSM-guided narrative video. First, content experts developed a video script containing information on HPV, HPV vaccines, and HPV-related cancers. The script and video contents were evaluated and refined, in succession, utilizing the think-aloud method, open-ended questions, and a brief survey during one-on-one interviews with university students.

Results

Script and video content analyses led to significant revisions that enhanced quality, informativeness, and relevance to the participants. We highlight the critical issues that were revealed and revised in the iterative process.

Conclusions

We developed and refined a CSM guided narrative video for diverse university students. This framework serves as a guide for developing health communication interventions for other populations and health behaviors.

Innovation

This project is the first to apply the ORBIT framework to HPV vaccination and describe a process to develop, evaluate, and refine comparable CSM guided narrative interventions that are tailored to specific audiences.

A prognostic model built on amino acid metabolism patterns in HPV-associated head and neck squamous cell carcinoma

OBJECTIVES

To compare amino acid metabolism patterns between HPV-positive and HPV-negative head and neck squamous cell carcinoma (HNSCC) patients and identify key genes for a prognostic model.

DESIGN

Utilizing the Cancer Genome Atlas dataset, we analyzed amino acid metabolism genes, differentiated genes between HPV statuses, and selected key genes via LASSO regression for the prognostic model. The model's gene expression was verified through immunohistochemistry in clinical samples. Functional enrichment and CIBERSORTx analyses explored biological functions, molecular mechanisms, and immune cell correlations. The model's prognostic capability was assessed using nomograms, calibration, and decision curve analysis.

RESULTS

We identified 1157 key genes associated with amino acid metabolism in HNSCC and HPV status. The prognostic model, featuring genes like IQCN, SLC22A1, SYT12, and TLX3, highlighted functions in development, metabolism, and pathways related to receptors and enzymes. It significantly correlated with immune cell infiltration and outperformed traditional staging in prognosis prediction, despite immunohistochemistry results showing limited clinical identification of HPV-related HNSCC.

CONCLUSIONS

Distinct amino acid metabolism patterns differentiate HPV-positive from negative HNSCC patients, underscoring the prognostic model's utility in predicting outcomes and guiding therapeutic strategies.

Exploring the Barriers and Facilitators Influencing Human Papillomavirus Vaccination Decisions Among South Asian and Chinese Mothers: a Qualitative Study

Human papillomavirus (HPV) vaccines are safe and effective in preventing HPV infection and HPV-related cancers. However, the HPV vaccine uptake rate is lower among the ethnic minority population than in the majority population. This qualitative study explored the barriers and facilitators influencing South Asian minority and Chinese mothers' decisions to vaccinate their daughters against HPV in Hong Kong. South Asian and Chinese mothers with at least one daughter aged 9 to 17 years were recruited to this study. Twenty-two semi-structured focus group interviews were conducted, and the transcripts were analysed via content analysis. Two barriers and three facilitating factors were common among South Asian and Chinese mothers: inadequate knowledge of cervical cancer, HPV or the HPV vaccine and high perceived barriers to HPV vaccination due to vaccine cost, the receipt of reliable information from schools or the government, high perceived benefits of HPV vaccination to health, and the presence of vaccination programme arranged by school or government. Despite these commonalities, South Asian mothers experienced more barriers to making the decision to vaccinate than Chinese mothers. Particularly, obtaining family support was an important factor for South Asian mothers. The vaccination decision was considered a joint decision between the mother and father, and the father's agreement was of particular importance to Pakistani mothers. This study identified the factors that hindered and facilitated South Asian and Chinese mothers' decisions to vaccinate their daughters against HPV. The comparison between groups improves our understanding of the distinct needs of South Asian in Hong Kong.

A Consolidated Framework for Implementation Research-based process to develop theoretically-informed human papillomavirus vaccination educational materials for young adults

OBJECTIVE

To develop theory-informed human papillomavirus (HPV) vaccine education materials that appeal to 18-26-year-olds.

METHODS

First, draft materials informed by Theory of Planned Behavior (TPB) and Health Belief Model (HBM) were developed. Next, an initial set of Consolidated Framework for Implementation Research (CFIR)-guided interviews were conducted with 18-26-year-old participants to receive feedback about content, format, appeal, implementation facilitators and barriers, and potential delivery modalities. Then, interviews were transcribed, coded, and analyzed using thematic analysis. Next, materials were modified based upon feedback. Finally, another set of interviews was conducted.

RESULTS

Most participants (n = 15) were female (93%), White (60%), and non-Hispanic (93%). All (100%) had heard of HPV and the HPV vaccine, and 80% reported having received the vaccine. Participant feedback on materials included emphasizing vaccine benefits and efficacy, rewording to enhance comprehension, and adding images represent diversity beyond race/ethnicity and sexual orientation. Suggested delivery methods included social media, print materials, and posters.

CONCLUSION

Qualitative interviews with young adults suggest that HPV education materials targeted to 18-26-year-olds should include health behavior theory-aligned messaging, inclusive imagery, and be disseminated through multiple modalities.

PRACTICE IMPLICATIONS

Providers should consider utilizing theory-based education materials that are relevant and appealing to young adults.

Assessing the performance and utility of targeted next-generation sequencing for screening and genotyping of human papillomaviruses

A next-generation sequencing (NGS)-based Ezplex HPV NGS kit (SML Genetree, Seoul, Korea) was used for human papillomavirus (HPV) screening. Of 885 cervical swab samples, HPV was detected in 162 samples. High-risk HPVs were detected in 82 samples, and other types of HPV were detected in 13 samples (HPV86, 71, 102, 91, and 114). At the read depth ≥ 500, NGS results exhibited 100 % agreement among repeated tests. HPV NGS results were compared with those of real-time PCR assays, Anyplex HPV28 (Seegene, Seoul, Korea) (n = 383) and Cobas HPV (Roche, Mannheim, Germany) (n = 64); concordances were 92.4 % and 95.0 %, respectively. Sanger sequencing of discordant results (n = 13) produced compatible results with those of HPV NGS. Pap smear abnormalities were detected in 31 patients (3.5 %), and 19 patients had high-risk HPV. Using HPV NGS for screening, rare HPV subtypes were detected, and quantitative values were obtained as read depth.

Practices of French General Practitioners Regarding Vaccination of Boys Against Human Papillomavirus (HPV), One Year After the Application of Its Official Recommendation

In 2019, French health authorities extended the recommendation for human papillomavirus (HPV) vaccination to include boys aged 11 to 19 years. We describe HPV vaccination practices among French general practitioners (GPs) since this recommendation wasapplied. We also identified factors associated with the propensity to propose HPV vaccination to boys. Cross-sectional study, between May and August 2022, among French GPs using a questionnaire asking about the GPs, their practices, and opinions regarding HPV vaccination, including whether they systematically proposed HPV vaccination to eligible boys or not. We investigated factors associated with systematic proposal of HPV vaccination, using univariate and multivariate logistic regression. In total, 360 GPs participated (76.6% females; mean age 34.7 ± 7.8 years; 22.9% had additional training in gynecology or pediatrics); 5.5% reported that they systematically offered HPV vaccination to boys prior to the recommendation, whereas 61.2% do so systematically since the recommendation. Factors associated with systematic proposal to boys (post recommendation) were female GP sex (78.6% versus 66.2%; OR = 2.0 [95% confidence interval (CI) 1.2-3.3]; p = 0.007) and systematic proposal prior to the recommendation (8.5% versus 0.7%; OR = 13.3 [1.7-101.7]; p = 0.01). Protection against HPV-induced cancer was cited as an argument to vaccinate girls (98.3% versus 89.2%; p < 0.0001); while reducing the risk of transmission was more commonly an argument to vaccinate boys (78.1% versus 51.8%; p < 0.0001). This study underlines the positive impact of the official recommendation for HPV vaccination of boys on the attitude of GPs, with an increase in the systematic proposal of HPV vaccination to boys.

Low Levels of Lifetime Pap Test Receipt Among Vulnerable Guatemalans

Low and middle-income countries, such as Guatemala, shoulder a disproportionate share of cervical cancer, a preventable disease in high income countries. Tangible obstacles, such as lack of access to health care, cultural differences, and insufficient infrastructure, and facilitators, such as being Ladino, married, and educated, have been identified in the literature related to cervical cancer prevention. The aim of this survey was to explore barriers and facilitators to cervical cancer prevention, comparing rural Indigenous and urban Ladino populations. We surveyed 139 women in two health clinics. Participants answered questions about demographic information, cervical cancer knowledge, and health care behaviors. We analyzed survey data with four bivariate models. Our results suggest vulnerable populations, such as rural Indigenous women who are single, illiterate, and lack education, face higher cervical cancer risk. Partnerships should be formed with health promotors and lay midwives to educate and encourage vulnerable populations to prevent cervical cancer.

Immunogenicity of quadrivalent human papillomavirus vaccine among Alaska Native children aged 9-14 years at 5 years after vaccination

BACKGROUND

Persistent human papillomavirus (HPV) infection can cause anogenital and oropharyngeal cancers. Many HPV infections and HPV-associated cancers are vaccine-preventable. Studies suggest long-term persistence of vaccine-induced antibodies. However, data are limited among Alaska Native people.

METHODS

During 2011-2014, we enrolled Alaska Native children aged 9-14 years who received a 3-dose series of quadrivalent HPV vaccine (4vHPV). We collected sera at 1 month and 1, 2, 3, and 5 years post-vaccination to evaluate trends in type-specific immunoglobulin G antibody concentrations for the 4vHPV types (HPV 6/11/16/18).

RESULTS

All participants (N = 469) had detectable antibodies against all 4vHPV types at all timepoints post-vaccination. For all 4vHPV types, antibody levels peaked by 1 month post-vaccination and gradually declined in subsequent years. At 5 years post-vaccination, antibody levels were higher among children who received 4vHPV at a younger age.

CONCLUSIONS

Alaska Native children maintained antibodies against all 4vHPV types at 5 years post-vaccination.

Comparison of HPV-positive triage strategies combining extended genotyping with cytology or p16/ki67 dual staining in the Italian NTCC2 study

BACKGROUND

Each high-risk HPV genotype has different oncogenic potential, and the risk of CIN3+ varies according to genotype. We evaluated the performance of different strategies of HPV-positivity triage combining cytology, p16/ki67 dual staining (DS), and extended genotyping.

METHODS

Samples from 3180 consecutive women from the NTCC2 study (NCT01837693) positive for HPV DNA at primary screening, were retrospectively analyzed by the BD Onclarity HPV Assay, which allows extended genotyping. Genotypes were divided into three groups based on the risk of CIN3+. HPV DNA-positive women were followed up for 24 months or to clearance.

FINDINGS

Combining the three groups of genotypes with cytology or DS results we identify a group of women who need immediate colposcopy (PPV for CIN3+ from 7.8 to 20.1%), a group that can be referred to 1-year HPV retesting (PPV in those HPV-positive at retesting from 2.2 to 3.8), and a group with a very low 24-month CIN3+ risk, i.e. 0.4%, composed by women cytology or DS negative and positive for HPV 56/59/66 or 35/39/68 or negative with the Onclarity test, who can be referred to 3-year retesting.

INTERPRETATION

Among the baseline HPV DNA positive/cytology or DS negative women, the extended genotyping allows to stratify for risk of CIN3+, and to identify a group of women with a risk of CIN3+ so low in the next 24 months that they could be referred to a new screening round after 3 years.

HPV16-miRNAs exert oncogenic effects through enhancers in human cervical cancer

BACKGROUND

Cervical cancer is a human papillomavirus (HPV)-related disease. HPV type 16 (HPV16), which is the predominant cause of cervical cancer, can encode miRNAs (HPV16-miRNAs). However, the role of HPV16-miRNAs in the pathogenesis of cervical cancer remains unclear.

METHODS

Human cervical cancer cell lines SiHa (HPV16-positive) and C33A (HPV-negative), and cervical cancer tissues were collected to investigate the expression levels of two HPV16-miRNAs (HPV16-miR-H1 and HPV16-miR-H6). The overexpression and knockdown of HPV16-miR-H1 and HPV16-miR-H6 were performed using the lentiviral vector system and miRNA inhibitors, respectively. RNA-sequencing (RNA-seq) analysis and H3K27ac chromatin immunoprecipitation and sequencing (CHIP-seq) experiments were utilized to explore the roles of HPV16-miR-H1 and HPV16-miR-H6 facilitated by enhancers. CCK8, EdU, transwell, and wound healing assays were performed to verify the effects of HPV16-miR-H1 and HPV16-miR-H6 on cell proliferation and migration.

RESULTS

HPV16-miR-H1 and HPV16-miR-H6 were highly expressed in both SiHa cells and tissue samples from HPV16-positive cervical cancer patients. RNA-seq analysis showed that HPV16-miR-H1 and HPV16-miR-H6 induced the upregulation of numerous tumor progression-associated genes. H3K27ac CHIP-seq experiments further revealed that HPV16-miR-H1 and HPV16-miR-H6 modulated the expression of critical genes by regulating their enhancer activity. The functional study demonstrated that HPV16-miR-H1 and HPV16-miR-H6 increased the migratory capacity of SiHa cells.

CONCLUSIONS

Our data shed light on the role of HPV16-encoded miRNAs in cervical cancer, particularly emphasizing their involvement in the miRNA-enhancer-target gene system. This novel regulatory mechanism of HPV16-miRNAs provides new insights and approaches for the development of therapeutic strategies by targeting HPV16-positive cervical cancer.

Human papillomavirus infection and the risk of cancer at specific sites other than anogenital tract and oropharyngeal region: an umbrella review

BACKGROUND

Despite numerous studies having evaluated the associations between human papillomavirus (HPV) infection and risk of specific cancers other than anogenital tract and oropharyngeal, the findings are inconsistent and the quality of evidence has not been systematically quantified. We aimed to summarise the existing evidence as well as to evaluate the strength and credibility of these associations.

METHODS

We conducted an umbrella review of systematic reviews and meta-analyses of observational studies. PubMed, EMBASE, and Web of Science were searched from inception to March 2024. Studies with systematic reviews and meta-analyses that examined associations between HPV or HPV-associated genotypes infection and specific cancers were eligible for this review. The quality of the methodology was evaluated using A Measurement Tool to Assess systematic Reviews (AMSTAR). The credibility of the evidence was assessed using GRADE. The protocol was preregistered with PROSPERO (CRD42023439070).

FINDINGS

The umbrella review identified 31 eligible studies reporting 87 associations with meta-analytic estimates, including 1191 individual studies with 336,195 participants. Of those, 29 (93.5%) studies were rated as over moderate quality by AMSTAR. Only one association indicating HPV-18 infection associated with an increased risk of breast cancer (odds ratio [OR] = 3.48, 95% confidence interval [CI] = 2.24-5.41) was graded as convincing evidence. There were five unique outcomes identified as highly suggestive evidence, including HPV infection increased the risk of oral squamous cell carcinoma (OR = 7.03, 95% CI = 3.87-12.76), oesophageal cancer (OR = 3.32, 95% CI = 2.54-4.34), oesophageal squamous cell carcinoma (OR = 2.69, 95% CI = 2.05-3.54), lung cancer (OR = 3.60, 95% CI = 2.59-5.01), and breast cancer (OR = 6.26, 95% CI = 4.35-9.00). According to GRADE, one association was classified as high, indicating that compared with the controls in normal tissues, HPV infection was associated with an increased risk of breast cancer.

INTERPRETATION

The umbrella review synthesised up-to-date observational evidence on HPV infection with the risk of breast cancer, oral squamous cell carcinoma, oesophageal cancer, oesophageal squamous cell carcinoma, and lung cancer. Further larger prospective cohort studies are needed to verify the associations, providing public health recommendations for prevention of disease.

Identifying effective vaccine champions: Findings from a national survey of primary care professionals

BACKGROUND

Vaccine champions are common in primary care, but little is known about which champions are effective.

METHODS

In 2022, we surveyed 2,144 US primary care professionals (PCPs) who reported working with vaccine champions. Respondents rated the champion with whom they worked most closely on their effectiveness at improving vaccination rates.

RESULTS

About half (49 %) of PCPs perceived their closest champion as highly effective. PCPs perceived advanced practice providers and nursing staff as highly effective somewhat more often than physicians (52 % and 58 % vs 43 %, p <.001). Other correlates of perceived effectiveness included being a formally appointed versus informal champion, working extremely versus less closely with PCPs, and using a high (4-5) versus low (0-1) number of implementation strategies to improve vaccination rates (all p <.001).

CONCLUSIONS

Results suggest vaccine champions may benefit from having formal roles and opportunities to work closely with colleagues to improve vaccination rates using multiple strategies.

The association between the human papillomavirus (HPV) and the diagnosis of bladder cancer: systematic review and meta-analysis

BACKGROUND

Bladder cancer (BC) is the seventh most common cancer worldwide. Not every infection ends as cancer, although the HPV-induced carcinogenesis is a complex process consequence of inflammation. To determine the association between human papillomavirus (HPV) and the diagnosis of bladder cancer.

METHODS

We carried out a systematic review according to Cochrane and PRISMA recommendations. We searched in EMBASE, Medline (Ovid), and The Cochrane Central Register of Controlled Trials (CENTRAL), from inception to nowadays. We included case-control studies. The risk of bias assessment was performed based on QUADAS2. We performed a random effect Meta-analysis.

RESULTS

We included 14 studies in qualitative and quantitative analysis. There was mainly a low risk of bias. We finally found a strong association between the presence of HPV and bladder cancer diagnosis (OR 4.18 95%CI 2.63-6.66; I2 = 40%).

CONCLUSIONS

HPV is currently associated with the diagnosis of bladder cancer.

Perceptions of Taiwanese college students toward human papillomavirus infection: A qualitative descriptive study

PURPOSE

The aim of this study was to explore college students' perceptions of human papillomavirus (HPV) infection and their thoughts on prevention measures.

DESIGN AND METHODS

A qualitative descriptive design was used. The study adopted purposive sampling at two universities in northern Taiwan and one in central Taiwan. Twenty-six college students participated, and data saturation was reached. Content analysis was undertaken.

RESULTS

Four main themes emerged from the data narratives: 1) having very little knowledge of HPV infection, 2) being concerned about outcomes of HPV infection, 3) taking measures to protect oneself, and 4) expecting to have HPV prevention resources.

CONCLUSIONS

The results indicated that college students needed a more complete understanding of HPV and prevention methods to protect themselves from infection. Schools were an ideal place to provide adequate information on HPV prevention.

PRACTICE IMPLICATIONS

The study suggested providing HPV-related information through school health centers and government health departments to resolve common questions and misunderstandings about HPV infection. Healthcare professionals should have a complete understanding of HPV-related knowledge in order to provide detailed information to young people.

Riddle of the Sphinx: Emerging role of circular RNAs in cervical cancer

Cervical cancer is a prominent cause of cancer-related mortality among women, with recent attention directed toward exploring the involvement of circular RNAs (circRNAs) in this particular cancer. CircRNAs, characterized by a covalently closed loop structure, belong to a class of single-stranded non-coding RNA (ncRNA) molecules that play crucial roles in cancer development and progression through diverse mechanisms. The abnormal expression of circRNAs in vivo is significantly associated with the development of cervical cancer. Notably, circRNAs actively interact with miRNAs in cervical cancer, leading to the regulation of diverse signaling pathways, and they can contribute to cancer hallmarks such as self-sufficiency in growth signals, insensitivity to antigrowth signals, limitless proliferation, evading apoptosis, tissue invasion and metastasis, and sustained angiogenesis. Moreover, the distinctive biomedical attributes exhibited by circRNAs, including their abundance, conservation, and stability in body fluids, position them as promising biomarkers for various cancers. In this review, we elucidate the tremendous potential of circRNAs as diagnostic markers or therapeutic targets in cervical cancer by expounding upon their biogenesis, characteristics, functions, and databases, highlighting the novel advances in the signaling pathways associated with circRNAs in cervical cancer.

Human papillomavirus vaccination uptake among 27-to-45-year-olds in the United States

OBJECTIVE

The human papillomavirus (HPV) vaccine prevents six types of cancer. Previously, this vaccine was only approved for 9-26-year-olds. However, in October 2018 the U.S. Food and Drug Administration approved the HPV vaccine for 27- to 45-year-olds (mid-adults). The current study aimed to assess HPV vaccination among a national sample of U.S adults aged 27-45 years. This study also assessed factors associated with HPV vaccine initiation after age 26.

METHODS

Data were analyzed using the 2019 National Health Interview Survey. The study included two samples: (1) mid-adults aged 27-45 (n = 8556), and (2) mid-adults who self-reported they had initiated HPV vaccination within the 27-45 age range and those who were unvaccinated (n = 7307). The outcome variables were HPV vaccination status and HPV vaccine initiation. The independent variables represented constructs from Andersen's Behavioral Model of Health Services Use. The odds of HPV vaccination were estimated using weighted multivariable logistic regression models.

RESULTS

Overall, 15.6% had ever received the HPV vaccine and 13.1% initiated their first dose of the vaccine after age 26. Hispanic (aOR = 0.73; 95% CI = 0.58, 0.92) and non-Hispanic Asian persons (aOR = 0.59; 95% CI = 0.41, 0.84) had lower odds of ever receiving the vaccine than non-Hispanic White persons. Females (aOR = 2.17; 95% CI = 1.42, 3.32) had higher odds of initiating the vaccine after age 26 than males.

CONCLUSIONS

The ACIP recommendation of shared clinical decision-making emphasizes the role of clinical interactions in HPV vaccine decision-making. Study findings highlight the need to further explore contextual factors that may influence HPV vaccine behavior among mid-adults.

Evaluating human papillomavirus testing, prevalence, and association with prognosis in head and neck squamous cell carcinoma by subsite: A national cancer database study

PURPOSE

To compare human papillomavirus (HPV) testing, prevalence, and association with prognosis between head and neck squamous cell carcinoma (HNSCC) subsites.

MATERIALS AND METHODS

This study utilized the National Cancer Database (NCDB) to identify patients diagnosed with HNSCC between 2010 and 2017. Rates of HPV testing, HPV-positivity, and changes in these rates over time were measured by subsite. The impact of HPV-positivity on overall survival across six head and neck subsites was assessed using multivariable-adjusted Cox proportional hazards analysis.

RESULTS

A total of 121,550 patients were included. Of this cohort, 87,575 (72.1%) were tested for HPV, with the oropharynx (55,049/64,158; 85.8%) displaying the highest rates of testing and the sinonasal tract (1519/2853; 53.2%) displaying the lowest testing rates. Of the 86,136 with a definitive result, 46,878 (54.4%) were HPV-positive, with the oropharynx (40,313/54,205; 74.4%) displaying the highest rates of HPV-positivity and the oral cavity (1818/11,505; 15.8%) displaying the lowest. HPV-positive malignancy was associated with significantly improved adjusted overall survival in the oropharynx (HR = 0.42 [95% CI: 0.43-0.47]), oral cavity (HR = 0.86 [95% CI: 0.79-0.95]), sinonasal tract (HR = 0.63 [95% CI: 0.48-0.83]), larynx (HR = 0.78 [95% CI: 0.71-0.87]), and hypopharynx (HR = 0.56 [95% CI: 0.48-0.66]), but not the nasopharynx (HR = 0.93 [95% CI: 0.77-1.14]).

CONCLUSION

HPV testing rates were significantly lower in non-oropharyngeal subsites. This is relevant as HPV-associated disease displayed significantly improved overall survival in both the oropharynx and four of five non-oropharyngeal subsites. While validation with prospective studies is necessary, these findings may warrant HPV testing in all HNSCC subsites.

Prevalence of cervical human papillomavirus in kidney transplant recipients: A systematic review and meta-analysis

OBJECTIVE

This systematic review and meta-analysis aims to investigate the prevalence of cervical high-risk human papillomavirus (hrHPV) among kidney transplant recipients (KTRs) and, furthermore to compare it to that in immunocompetent controls.

METHODS

A systematic literature search was conducted in PubMed, EMBASE, and Cochrane Library databases from January 2000 to February 2023, to identify studies investigating the prevalence of cervical hrHPV in KTRs. Pooled cervical hrHPV prevalences, odds ratios (ORs) comparing KTRs to controls and corresponding confidence intervals (CIs) were estimated using random effects logistic regression models. Heterogeneity between studies was assessed through the I2 statistic, and the significance was evaluated by the Cochrane's Q test.

RESULTS

Altogether, 16 studies covering >1200 KTRs were included. The prevalence of cervical hrHPV in KTRs was 27.7% (95% CI 21.3-35.1) with substantial interstudy heterogeneity. Stratification indicated a higher prevalence in recent years (2019-2023) and in Asia (39% (95% CI 11.2-61.4)). The prevalence of HPV16 and HPV18 in KTRs was 8.0% (95% CI 3.9-15.9) and 1.7% (95% CI 0.8-3.7), respectively. Comparing hrHPV prevalence in KTRs and controls based on six studies including >500 KTRs and 1000 controls, the OR for hrHPV was 2.0 (95% CI 1.1-3.6).

CONCLUSIONS

This meta-analysis establishes an increased cervical hrHPV prevalence in KTRs compared to controls. The increased risk may be associated with immunosuppressive therapy post-transplantation. Further research is needed to explore the potential benefits of HPV vaccination, including potential revaccination strategies in KTRs.

Outcomes of transoral robotic surgery for early-stage oropharyngeal squamous cell carcinoma with low rates of adjuvant therapy: A consecutive single-institution study from 2013 to 2020

INTRODUCTION

The incidence of oropharyngeal squamous cell carcinoma (OPSCC) has increased in recent decades, driven by infection with human papillomavirus (HPV). Transoral robotic surgery (TORS) and neck dissection (ND) has been employed as an alternative to radiotherapy/chemoradiotherapy. The current literature is lacking studies providing an exhaustive overview of recurrence characteristics and long-term outcomes in TORS-treated OPSCC-patients.

METHODS

All patients treated for OPSCC with primary TORS + ND in Eastern Denmark between 2013 and 2020 were included in the study. The aim was to explore overall survival (OS), recurrence-free survival (RFS), recurrence patterns, and ultimate failure rate (UFR). OS and RFS were examined using the Kaplan-Meier method. Cox proportional regression analyses were employed to examine effect of different variables on risk of death and recurrence.

RESULTS

The study included 153 patients of which 88.9 % (n = 136) were treated with TORS alone while 11.1 % (n = 17) received adjuvant therapy. The 1-, 3-, and 5-year OS were 97.4 %, 94.1 %, and 87.6 % while 1-, 3-, and 5-year RFS were 96.6 %, 87.8 %, and 84.9 %. The UFR was 6.5 % in the cohort. Patients with HPV+/p16 + OPSCC had a significantly better 5-year OS of 92.3 % than patients with discordant or double-negative HPV/p16 status (OS = 73.3 %). No differences in outcomes between patients treated with or without adjuvant therapy were found in regression analysis.

CONCLUSION

Excellent survival and disease control was obtained with TORS + ND in this cohort, despite lesser application of adjuvant therapy than other TORS-centers, implying that TORS without adjuvant therapy can be successfully applied in treatment of early-stage OPSCC.

Performance of a vaginal self-collection device versus clinician collected cervical samples for the detection of high-risk human papillomavirus

Objective

Screening for cervical cancer requires the participation of target women. Human papillomavirus (HPV) testing can be performed on vaginal self-samples and self-sampling can improve this participation. This study aims to validate the performance of the vaginal self-sampling device (Vitroveil®) to detect high risk human papillomavirus (hrHPV) in comparison to clinician collected samples and evaluate the degree of acceptability of the Vitroveil® device.

Methods

A cross-sectional observational study was carried out in a cohort of 385 participating women (median age of 44 ± 10.47 years) attending primary care centers and cervical pathology services of Granada, Spain. Two paired samples (vaginal self-sample and clinician collected cervical sample) where collected from each participant to compare the detection of HPV with the Vitro HPV Screening assay (Vitro, Granada, Spain). A questionnaire was also provided to the participants to analyze the degree of satisfaction with the device and the preference for sampling method.

Results

Overall concordance for hrHPV detection was substantial (ĸ 0.804). The prevalence of any hrHPV infection was higher in self-collected samples (30.6%) than in clinician-collected samples (24.3%). The participants found the self-sampling device easy to use and preferred self-collection as the collection method.

Conclusion

The Vitroveil® self-sampling device enables safe and accruable hrHPV testing, obtaining equivalent results to those of the clinician collected samples. High acceptability of the device has been demonstrated among women in the study. Nevertheless, additional studies are necessary to verify the efficacy and reliability of the device's performance.

Clinical and prognostic differences in oropharyngeal squamous cell carcinoma in USA and Denmark, two HPV high-prevalence areas

BACKGROUND

Uncertainty persists regarding clinical and treatment variations crucial to consider when comparing high human papillomavirus (HPV)-prevalence oropharyngeal squamous cell carcinoma (OPSCC) cohorts for accurate patient stratification and replicability of clinical trials across different geographical areas.

METHODS

OPSCC patients were included from The University of Texas MD Anderson Cancer Center (UTMDACC), USA and from The University Hospital of Copenhagen, Denmark from 2015-2020, (n = 2484). Outcomes were 3-year overall survival (OS) and recurrence-free interval (RFI). Subgroup analyses were made for low-risk OPSCC patients (T1-2N0M0) and high-risk patients (UICC8 III-IV).

RESULTS

There were significantly more HPV-positive (88.2 % vs. 63.1 %), males (89.4 % vs. 74.1 %), never-smokers (52.1 % vs. 23.7 %), lower UICC8-stage (I/II: 79.3 % vs. 68 %), and fewer patients treated with radiotherapy (RT) alone (14.8 % vs. 30.3 %) in the UTMDACC cohort. No difference in the adjusted OS was observed (hazard ratio [HR] 1.21, p = 0.23), but a significantly increased RFI HR was observed for the Copenhagen cohort (HR: 1.74, p = 0.003). Subgroup analyses of low- and high-risk patients revealed significant clinical and treatment differences. No difference in prognosis was observed for low-risk patients, but the prognosis for high-risk patients in the Copenhagen cohort was worse (OS HR 2.20, p = 0.004, RFI HR 2.80, p = 0.002).

CONCLUSIONS

We identified significant differences in clinical characteristics, treatment modalities, and prognosis between a Northern European and Northern American OPSCC population. These differences are important to consider when comparing outcomes and for patient stratification in clinical trials, as reproducibility might be challenging.

Geographic variation of HPV-associated cancer incidence in Kentucky using spatial scan statistics

PURPOSE

Populations with high cancer risk that are targeted for screening, education, and vaccination have been shown to increase rates of screening, which ultimately may improve timing of diagnosis and overall outcome for certain cancers. Spatial scan analysis provides a visual representation of areas with higher rates of disease. Limited research has used this methodology to assess HPV-associated cancers. Using, spatial scan statistics, our goal was to identify regions within Kentucky having significantly higher rates of HPV-associated tumors. These regions can be targeted for public health efforts in the form of education, vaccination, screening, and physician recruitment.

METHODS

The Kentucky Cancer Registry data from 1995 to 2016 and spatial scan statistics were used to identify county-level clusters with high-incidence of HPV-associated cancers after adjustment for age and sex. Anatomic sites included in this analysis were oropharynx, cervix, anus, penis, and vulva.

RESULTS

There was one high-rate cluster of oropharyngeal cancer, which was observed in the Louisville metropolitan region (Relative Risk [RR] = 1.24, p < 0.001). One high-rate cluster of anal and penile cancer incidence in men was identified that partially overlapped with the oropharyngeal cluster. There were five clusters of higher cervical, vulvar, and anal cancer incidence in females, one of which overlapped with the oropharyngeal cluster.

CONCLUSION

Overlapping clusters of HPV-associated cancers were identified at the county-level and included both urban and rural counties of Kentucky. Findings can assist in the design of public health interventions to increase screenings, promote vaccination, and recruit physicians in these regions to improve prevention, diagnosis, and early treatment of HPV-associated cancers.

Seegene Anyplex II Assays Detect HPV Consistently Using DNA Extracts from Different Extraction Methods

The efficiency of PCR-based diagnostic assays can be impacted by the quality of DNA template, and anal samples can be particularly problematic due to the presence of faecal contaminants. Here we compared the Quick-DNA Viral Kit (Zymo, Zymo Research, CA) and MagNA Pure 96 DNA and Viral NA Small Volume Kit (MP96, Roche), for use of the Seegene Anyplex II HPV28 assay (Anyplex28, Seegene) with anal samples. Total of 94 anal samples extracted using the MP96 and Zymo kits were tested via the Anyplex28, which detects high-risk human papillomavirus (HR-HPV, Panel A) and low-risk (LR-HPV, Panel B) HPV types. Testing the HR-HPV types (Panel A), 86 (91.5%) MP96 and 84 (89.4%) Zymo samples were deemed assessable. Overall agreement between the two methods was 87/94 (92.6%, 95% CI: 85.3-97.0) with the Kappa value of 0.678 (0.5-0.9). Of the 87 assessable samples, 50 (57.5%) were concordant, 34 (39.1%) partially concordant, and 10 (11.5%) discordant. In conclusion, the Anyplex28 produces comparable HPV genotyping results when using DNA extracts from either of these two methods.

Fully automated 3D machine learning model for HPV status characterization in oropharyngeal squamous cell carcinomas based on CT images

BACKGROUND

Human papillomavirus (HPV) status plays a major role in predicting oropharyngeal squamous cell carcinoma (OPSCC) survival. This study assesses the accuracy of a fully automated 3D convolutional neural network (CNN) in predicting HPV status using CT images.

METHODS

Pretreatment CT images from OPSCC patients were used to train a 3D DenseNet-121 model to predict HPV-p16 status. Performance was evaluated by the ROC Curve (AUC), sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and F1 score.

RESULTS

The network achieved a mean AUC of 0.80 ± 0.06. The best-preforming fold had a sensitivity of 0.86 and specificity of 0.92 at the Youden's index. The PPV, NPV, and F1 scores are 0.97, 0.71, and 0.82, respectively.

CONCLUSIONS

A fully automated CNN can characterize the HPV status of OPSCC patients with high sensitivity and specificity. Further refinement of this algorithm has the potential to provide a non-invasive tool to guide clinical management.

Three-dimensional chromatin analysis reveals Sp1 as a mediator to program and reprogram HPV-host epigenetic architecture in cervical cancer

Human papillomavirus (HPV) is predominantly associated with HPV-related cancers, however, the precise mechanisms underlying the HPV-host epigenetic architectures in HPV carcinogenesis remain elusive. Here, we employed high-throughput chromosome conformation capture (Hi-C) to comprehensively map HPV16/18-host chromatin interactions. Our study identified the transcription factor Sp1 as a pivotal mediator in programming HPV-host interactions. By targeting Sp1, the active histone modifications (H3K27ac, H3K4me1, and H3K4me3) and the HPV-host chromatin interactions are reprogrammed, which leads to the downregulation of oncogenes located near the integration sites in both HPV (E6/E7) and the host genome (KLF5/MYC). Additionally, Sp1 inhibition led to the upregulation of immune checkpoint genes by reprogramming histone modifications in host cells. Notably, humanized patient-derived xenograft (PDX-HuHSC-NSG) models demonstrated that Sp1 inhibition promoted anti-PD-1 immunotherapy via remodeling the tumor immune microenvironment in cervical cancer. Moreover, single-cell transcriptomic analysis validated the enrichment of transcription factor Sp1 in epithelial cells of cervical cancer. In summary, our findings elucidate Sp1 as a key mediator involved in the programming and reprogramming of HPV-host epigenetic architecture. Inhibiting Sp1 with plicamycin may represent a promising therapeutic option for HPV-related carcinoma.

Single-cell Atlas of Penile Cancer Reveals TP53 Mutations as a Driver of an Aggressive Phenotype, Irrespective of Human Papillomavirus Status, and Provides Clues for Treatment Personalization

BACKGROUND AND OBJECTIVE

TP53 loss-of-function (TP53LOF) mutations might be a driver of poor prognosis and chemoresistance in both human papillomavirus (HPV)-independent (HPV-) and HPV-associated (HPV+) penile squamous cell carcinoma (PSCC). Here, we aim to describe transcriptomic differences in the PSCC microenvironment stratified by TP53LOF and HPV status.

METHODS

We used single-cell RNA sequencing (scRNA-seq) and T-cell receptor sequencing to obtain a comprehensive atlas of the cellular architecture of PSCC. TP53LOF and HPV status were determined by targeted next-generation sequencing and sequencing HPV-DNA reads. Six HPV+ TP53 wild type (WT), six HPV- TP53WT, and four TP53LOF PSCC samples and six controls were included. Immunohistochemistry and hematoxylin-eosin confirmed the morphological context of the observed signatures. Prognostic differences between patient groups were validated in 541 PSCC patients using Kaplan-Meier survival estimates.

KEY FINDINGS AND LIMITATIONS

Patients with aberrant p53 staining fare much worse than patients with either HPV- or HPV+ tumors and WT p53 expression. Using scRNA-seq, we revealed 65 cell subtypes within 83 682 cells. TP53LOF tumors exhibit a partial epithelial-to-mesenchymal transition, immune-excluded, angiogenic, and morphologically invasive environment, underlying their aggressive phenotype. HPV- TP53WT tumors show stemness and immune exhaustion. HPV+ TP53WT tumors mirror normal epithelial maturation with upregulation of antibody-drug-conjugate targets and activation of innate immunity. Inherent to the scRNA-seq analysis, low sample size is a limitation and validation of signatures in large PSCC cohorts is needed.

CONCLUSIONS AND CLINICAL IMPLICATIONS

This first scRNA-seq atlas offers unprecedented in-depth insights into PSCC biology underlying prognostic differences based on TP53 and HPV status. Our findings provide clues for testing novel biomarker-driven therapies in PSCC.

PATIENT SUMMARY

Here, we analyzed tissues of penile cancer at the level of individual cells, which helps us understand why patients who harbor a deactivating mutation in the TP53 gene do much worse than patients lacking such a mutation. Such an analysis may help us tailor future therapies based on TP53 gene mutations and human papillomavirus status of these tumors.

Willingness and hesitancy towards the governmental free human papillomavirus vaccination among parents of eligible adolescent girls in Shenzhen, Southern China

BACKGROUND

Since 2020, China has actively promoted HPV vaccination for eligible adolescent girls through various pilot programmes. This study investigated parental willingness and hesitancy towards the government-sponsored, free human papillomavirus (HPV) vaccination for eligible adolescent girls in Shenzhen, Southern China.

METHODS

From June to August 2022, a cross-sectional survey was conducted with parents of girls entering Grade 7, employing an adapted Vaccine Hesitancy Scale to assess vaccine hesitancy and logistic regression to identify factors influencing willingness to accept the free domestic vaccines.

RESULTS

Although only 3.4% of the 2856 respondents had their daughters vaccinated against HPV prior to the survey, 91.7% were willing to utilise the governmental vaccination services. Parents with children in public schools (χ2 = 20.08, p < 0.001), those with more secure medical insurance (χ2 = 4.97, p = 0.026), and parents who had received an HPV vaccine themselves (χ2 = 28.829, p < 0.001) showed more reluctance towards the free vaccines. Vaccine hesitancy was presented in a mere 2.1% but was a significant predictor of vaccine refusal, even after adjusting for multiple factors (adjusted OR = 15.98, 95% CI: 9.06, 28.20). Notably, about four-fifths of parents of unvaccinated daughters harboured concerns about the safety and efficacy of the domestic vaccine.

CONCLUSIONS

Although parents show a strong inclination to utilise the government vaccination services, their vaccine hesitancy, driven by safety concerns and a preference for imported vaccines, remains a significant barrier for rolling out vaccination coverage. This study highlights the need for multifaceted intervention strategies that address these issues to enhance HPV vaccine uptake effectively.

Acceptability of self-collected vaginal samples for human papillomavirus testing for primary cervical cancer screening: comparison of face-to-face and online recruitment modes

BACKGROUND

This study aimed to assess the acceptability and attitudes of women towards human papillomavirus (HPV) self-sampling and compare the effectiveness of two delivery modes utilising face-to-face and online website for cervical cancer screening in Hong Kong.

METHODS

Women aged 30-65 years were invited to participate by distributing the study information pamphlets at the specialist clinics of a regional acute hospital. Those who were interested in participating were given the option to join directly face-to-face or through an online website. All participants provided informed consent and received self-sampling kits and acceptability questionnaires either immediately (face-to-face) or through the post after registering at the website (online). All participants were requested to collect their own vaginal samples using a swab which was then brushed on a DNA sample storage card and returned to the hospital either in person or by post. The self-collected samples were tested for high-risk HPV using the Sentis™ HPV assay, a validated isothermal nucleic acid amplification real-time fluorescent detection assay. The primary outcome was the uptake rate of HPV self-sampling.

RESULTS

Of the 1998 women recruited (1200 face-to-face, 798 online), 1377 returned their samples, giving an overall uptake rate of 68.9%. The uptake rate was significantly greater in the face-to-face mode than in the online mode (74.6% vs. 60.4%, p < 0.001). The median age of the participants was 49 years, 43.7% were never or under-screened, and 7.1% had high-risk HPV detected. Overall, 82.1% of the participants reported self-sampling convenient, and 79.3% were not embarrassed when collecting self-samples. However, only 49.8% were confident that they had collected the self-samples correctly. Most (91.1%) of the participants expressed willingness to perform self-sampling again, mostly because it was simple (79.2%) and quick (56.3%).

CONCLUSIONS

HPV self-sampling can serve as an alternative primary screening method for cervical cancer in Hong Kong, especially for individuals who have not been adequately screened in the past. Both face-to-face and online website recruitment were associated with high acceptability, emphasising the potential benefits of utilising different platforms and strategies for reaching diverse populations.

Bowen's disease revealing a penile invasive squamous cell carcinoma: Case report and review of literature

INTRODUCTION

Bowen's disease (BD) represents an in situ squamous cell carcinoma that can progress to an invasive one without treatment. Various options for Bowen's disease have been delineated, each with its set of advantages and disadvantages.

CASE PRESENTATION

We report the case of a 60-year-old patient with a history of chronic smoking and a background of multiple partners and recurrent urethritis. The patient presented with a maculopapular lesion on the lateral aspect of the penis, evolving for 5 years. A biopsy confirmed the diagnosis of Bowen's disease. The patient underwent an excision of the lesion which the histology showed an infiltrating basosquamous cell carcinoma.

DISCUSSION

The diagnosis of Bowen's disease requires a biopsy and is based on histological examination. Only surgical treatment allows for the identification, through histological analysis of the excised specimen, of any potential invasive area that may not have been identified in the biopsy. Nonsurgical therapies are also an option with high recurrence rates.

CONCLUSION

Bowen's disease management requires a personalized approach, considering factors like lesion characteristics, patient-related variables and treatment efficacy. An adapted follow-up is recommended due to the recurrence risk associated with various treatments.

Cervicovaginal microbiota: a promising direction for prevention and treatment in cervical cancer

Cervical cancer is a common malignancy in women, with high incidence rate and mortality. Persistent infection of high-risk human papillomavirus (HPV) is the most important risk factor for cervical cancer and precancerous lesions. Cervicovaginal microbiota (CVM) plays an essential role in the defense of HPV infections and prevention of subsequent lesions. Dominance of Lactobacillus is the key of CVM homeostasis, which can be regulated by host, exogenous and endogenous factors. Dysbiosis of CVM, including altered microbial, metabolic, and immune signatures, can contribute to persist HPV infection, leading to cervical cancer. However, there is no evidence of the causality between CVM and cervical cancer, and the underlying mechanism remains unexplored. Considering the close correlation between CVM dysbiosis and persistent HPV infection, this review will overview CVM, its role in cervical cancer development and related mechanisms, and the prospects for therapeutic applications.

Do boys have the same intentions to get the HPV vaccine as girls? Knowledge, attitudes, and intentions in France

BACKGROUND

The vaccine coverage against human papillomavirus (HPV) vaccination remains low in France. The objective of this study was to study adolescent perceptions by comparing boys and girls, in order to build effective school-based interventions.

METHODS

This paper presents a cross-sectional study in French middle school pupils. They completed online questionnaires on their knowledge and attitudes toward the HPV vaccine, HPV vaccination status, their intention, reasons to vaccinate or not to vaccinate, and psychological antecedents of vaccination. A structural equation modeling (SEM) analysis was used to test the hypothesized model.

RESULTS

The participants are 818 pupils aged from 12 to 16 years (Mage = 13.78). Most pupils were in the pre-contemplative stage (62.7 % of boys and 40.8 % of girls). SEM analysis indicated that the relationship between the level of HPV knowledge, the representations of vaccines in general, and vaccine intention was mediated by attitudes towards the HPV vaccine among both boys and girls.

CONCLUSIONS

These findings reveal a high percentage of boys who do not feel concerned by the HPV vaccine and highlight the need to consider the psychological antecedents of vaccination in general in addition to the specific attitudes to the HPV vaccine.

Clinical characteristics, HPV involvement, and demographic risk factors in women with cervical intraepithelial neoplasia complicated by vaginal intraepithelial neoplasia

PURPOSE

This study aimed to explore the clinical characteristics and risk factors associated with cervical intraepithelial neoplasia (CIN) when coexisting with vaginal intraepithelial neoplasia (VAIN).

METHODS

We analyzed the clinical data of 212 patients diagnosed with CIN, including 50 patients with concurrent VAIN. The groups were compared to identify distinct clinical features and independent risk factors for the co-occurrence of CIN and VAIN, using logistic regression analysis.

RESULTS

Patients with both CIN and VAIN had a median age of 57, significantly older than the 41-year median age of patients with CIN only (P < 0.05). A higher prevalence of HPV infection (98.0%) was observed in the CIN and VAIN group, with a notable rate of multiple HPV infections (67.3%) compared to the CIN-only group (P < 0.05). Educational levels were significantly lower in the combined CIN and VAIN group (P < 0.05). HPV16, 33, and 52 were identified as significant types for single and multiple infections. Multivariate analysis confirmed age as an independent risk factor for CIN with VAIN (P < 0.05). VAIN3 patients were more likely to exhibit HSIL and ASC-H, whereas VAIN1 cases tended to correspond with ASCUS and LSIL diagnoses.

CONCLUSION

The co-occurrence of CIN and VAIN is significantly influenced by patient age and educational level. The findings advocate for more diligent vaginal examination during colposcopy in older patients, particularly those with multiple HPV infections and cytological abnormalities, to enhance the early detection of vaginal lesions and prevent missed diagnoses and treatments. Additionally, the high prevalence of HPV infection, especially with certain types, underscores the importance of HPV monitoring in this patient population.

Interaction studies between human papillomavirus virus-like particles and laminin 332 by affinity capillary electrophoresis assisted by bio-layer interferometry

Human papillomavirus (HPV) interacts, in vitro, with laminin 332 (LN332), a key component of the extracellular matrix. In this study, we performed bio-layer interferometry (BLI) and affinity capillary electrophoresis (ACE) to investigate the binding properties of this interaction. Virus-like particles (VLPs), composed of the HPV16 L1 major capsid protein, were used as HPV model and LN332 as the VLPs binding partner. Using BLI, we quantitatively determined the kinetics of the interaction, via the measurement of VLP binding and release from LN332 immobilized onto the surface of aminopropylsilane biosensors. We found an averaged kon of 1.74 x 104 M-1s-1 and an averaged koff of 1.50 x 10-4 s-1. Furthermore, an ACE method was developed to study the interaction under physiological conditions, where the interactants are moving freely in solution, without any fluorescence labeling. Specifically, a constant amount of HPV16-VLPs was preincubated with increasing LN332 concentrations and then the samples were injected in the capillary electrophoresis instrument. A shift in the migration time of the HPV16-VLP/LN332 complexes, carrying an increasing number of LN332 molecules bound per VLP, was observed. The mobility of the complexes was found to decrease with increasing LN332 concentrations in the sample. It was used to quantify stability constant. From BLI and ACE approaches, we reported an apparent equilibrium dissociation constant in the nanomolar range (8.89 nM and 17.7 nM, respectively) for the complex between HPV16-VLPs and LN332.

Multiple-Digit Pigmented Bowen's Disease Induced by Human Papillomavirus in an Immunocompetent Child

Introduction

Bowen's disease is a squamous cell carcinoma in situ, the most common malignancy of the nail unit. Presenting more frequently in the fingernails, common risk factors include ionizing radiation, oral exposure to arsenic or pesticides, dyskeratosis congenita, and quite commonly diverse subtypes of HPV. We report the first case of multiple periungual pigmented Bowen's disease in a pediatric patient.

Case Presentation

A healthy 13-year-old boy presented with a 9-month history of a pigmented erythematous patch on the proximal nail fold of his 3rd right finger without associated symptoms. A punch biopsy was taken, and the diagnosis of Bowen's disease was made. The patient received photodynamic therapy and three cycles of imiquimod without response, and two new lesions appeared on the first and second right fingers. Surgical removal was performed on all lesions. A polymerase chain reaction detected an HPV type 16.

Discussion/Conclusion

Multiple periungual Bowen's disease is rare, with the most frequent risk factors being HPV infection and chronic immunosuppression. Less than 10% of the cases present as longitudinal melanonychia. To date, there are no previous reports of multiple pigmented periungual Bowen's disease. HPV-induced Bowen's disease is usually present in adults aged between 22 and 89 years as persistent verrucae. In this case, koilocytosis and the fact that all lesions appeared on the right hand are suggestive of HPV infection.

Human papillomavirus (HPV) load is higher in HPVDNA/p16 positive than in HPVDNA positive/p16 negative oropharyngeal squamous cell carcinoma but does not differ significantly between various subsites or correlate to survival

OBJECTIVE

Patients with human papillomavirus DNA positive (HPVDNA+) and p16ink4a overexpressing (p16+) oropharyngeal squamous cell carcinoma (OPSCC), especially those with cancer in the tonsillar and base of tongue subsites as compared to other OPSCC subsites have a better outcome than those with only HPVDNA+ or only p16+ cancer. Likewise having a high viral load has been suggested to be a positive prognostic factor. We therefore hypothesized, that HPV viral load could vary depending on OPSCC subsite, as well as with regard to whether the cancer was HPVDNA+ and p16+, or only HPVDNA+, or only p16+ and that this affected outcome.

MATERIAL AND METHODS

To address these issues HPV viral load was determined by HPV digital droplet (dd) PCR in tumor biopsies with previously known HPVDNA/p16 status from 270 OPSCC patients diagnosed 2000-2016 in Stockholm, Sweden. More specifically, of these patients 235 had HPVDNA+/p16+, 10 had HPVDNA+/p16-, 13 had HPVDNA-/p16+ and 12 had HPVDNA-/p16- cancer.

RESULTS

We found that HPVDNA+/p16+ OPSCC had a significantly higher viral load than HPVDNA+/p16- OPSCC. Moreover, there was a tendency for a higher viral load in the tonsillar and base of tongue OPSCC subsites compared to the other subsites and for a low viral load to correlate to a better clinical outcome but none of these tendencies reached statistical significance.

CONCLUSION

To conclude, the mean viral load in HPVDNA+/p16+ OPSCC was higher than in HPVDNA+/p16- OPSCC, but there was no statistically significant difference in viral load depending on OPSCC subsite or on clinical outcome.

Awareness of the causal association between human papillomavirus and anal cancer among US adults

PURPOSE

The incidence of anal cancer is on the rise in the US, especially among high-risk groups. This study examined the prevalence and determinants of awareness of the causal relationship between HPV and anal cancer among US adults.

METHODS

Study data was obtained from the 2017 to 2020 iterations of the Health Information National Trends Survey. The prevalence of awareness that HPV causes anal cancer was estimated among HINTS respondents who were aware of HPV in general. Survey weights were used to provide estimates representative of the adult US population. Multivariable logistic regressions were used to examine the associations between awareness that HPV causes anal cancer and cancer-related behaviors/perceptions and sociodemographic characteristics of respondents.

RESULTS

Two thousand six hundred and eighty four (27.2%) of the study population were aware that HPV caused anal cancer. Those of gay sexual orientation were more aware than heterosexuals [OR 2.27; 95% CI (1.24, 4.14)]. Compared to respondents with a high school diploma or less, individuals with some college education [OR 1.38; 95% CI (1.03, 1.85)] and those with at least a college degree [OR 1.52; 95% CI (1.17, 1.98)] were more likely to be aware. Participants who had positive cancer information seeking behavior were more aware of the HPV-anal cancer link compared to those who did not [OR 1.57; 95% CI (1.30, 1.89)].

CONCLUSION

Population-level awareness that HPV causes anal cancer remains critically low in the US. Sexual orientation, level of education and cancer information seeking behavior are associated with increased awareness of the causal relationship between HPV and anal cancer. Efforts should be directed toward addressing the awareness gap among individuals with lower education levels and promoting curiosity-driven information seeking behaviors.

Factors associated with HPV-associated sexual risk behaviors among sexually active college students

High-risk sexual behavior is the primary risk factor for the acquisition and persistence of human papillomavirus (HPV) infection and the development of HPV-associated diseases including cancer. Incidence of HPV infection is high among individuals in their late teens and early 20s. Thus, college students represent a historically high-risk group for HPV infection yet are also a group with the ability to independently access HPV vaccination for HPV prevention. To inform future interventions, we examined factors associated with HPV-associated risky sexual behaviors among sexually active college students. Data (N = 741) were from an anonymous online survey distributed to students at a public Midwestern university in 2021. The outcomes were HPV-associated sexual risk behaviors-number of oral or vaginal sexual partners [high (≥ 5) or low (< 5)] and age of oral or vaginal sexual debut [early (< 18 years) or late (≥ 18 years)]. Multivariable logistic regression models estimated the association between HPV-associated risky sexual behaviors and several predictors including age, gender, relationship status, academic level, country of birth, and rural-urban status. Among sexually active students, approximately 47% and 41% had a high number of lifetime vaginal and oral partners, respectively. Among the same group, 60% and 64% had early vaginal and oral sexual debut. Students who were single and dating (aOR = 1.93; 95% CI = 1.21, 3.08) or single and not dating (2.11; 1.28, 3.48) were more likely to have a high number of vaginal lifetime partners compared with married students. Single (vs. married) students were also about twice as likely to have a high number of oral lifetime partners. Relative to graduate students, freshmen/sophomores were more likely to have an early vaginal (2.44; 1.45, 4.11) and oral (2.14; 1.26, 3.63) sexual debut. Interventions tailored to college freshmen/sophomores and unmarried students should encourage students to receive the HPV vaccine for prevention of future HPV-associated diseases.

Human papillomavirus negative high grade cervical lesions and cancers: Suggested guidance for HPV testing quality assurance

BACKGROUND

Some high-grade cervical lesions and cervical cancers (HSIL+) test negative for human papillomavirus (HPV). The HPV-negative fraction varies between 0.03 % and 15 % between different laboratories. Monitoring and extended re-analysis of HPV-negative HSIL+ could thus be helpful to monitor performance of HPV testing services. We aimed to a) provide a real-life example of a quality assurance (QA) program based on re-analysis of HPV-negative HSIL+ and b) develop international guidance for QA of HPV testing services based on standardized identification of apparently HPV-negative HSIL+ and extended re-analysis, either by the primary laboratory or by a national HPV reference laboratory (NRL).

METHODS

There were 116 initially HPV-negative cervical specimens (31 histopathology specimens and 85 liquid-based cytology samples) sent to the Swedish HPV Reference Laboratory for re-testing. Based on the results, an international QA guidance was developed through an iterative consensus process.

RESULT

Standard PCR testing detected HPV in 55.2 % (64/116) of initially "HPV-negative" samples. Whole genome sequencing of PCR-negative samples identified HPV in an additional 7 samples (overall 61.2 % HPV positivity). Reasons for failure to detect HPV in an HSIL+ lesion are listed and guidance to identify cases for extended re-testing, including which information should be included when referring samples to an NRL are presented.

CONCLUSION

Monitoring the proportion of and reasons for failure to detect HPV in HSIL+ will help support high performance and quality improvement of HPV testing services. We encourage implementation of QA strategies based on re-analysis of "HPV negative" HSIL+ samples.

Parental Knowledge of HPV Infection, Cervical Cancer and the Acceptance of HPV Vaccination for their Children in Jos, Nigeria

Background

Despite the high prevalence of human papillomavirus (HPV) infections and cervical cancer in Nigeria, the utilization of the HPV vaccine as a highly effective preventive measure remains low. The aim of this study was to find out if parental knowledge of HPV infection and cervical cancer influenced the acceptance of HPV vaccines for their 9-14-year-old children.

Materials and Methods

This was a cross-sectional survey of 509 parents comprising 262 fathers and 247 mothers in 8 randomly selected communities in Jos, Plateau State Nigeria. A pretested semi-structured investigator-administered questionnaire, without identifiers, was used to collect information on parental knowledge of HPV, cervical cancer, HPV vaccine and its acceptance for their 9-14-year-old children. The data were analysed using SPSS version 23.0. Bivariate analysis was done using chi-square statistical test. Point estimates with corresponding 95% confidence interval (CI) were estimated with a value of P ≤ 0.05 was considered as statistically significant.

Results

Five hundred and nine parents were interviewed. The mean age of the respondents was 43.7 ± 9.43 years. Most of the participants (86.1%) had formal education from primary to tertiary level. Only 1.60%, 11.60% and 1.62% of respondents had knowledge of HPV, cervical cancer and HPV vaccines respectively, whereas 67.8% of parents were willing to pay for the cancer-preventing HPV vaccines out-of-pocket. There was no statistically significant associations between parental level of education (P = 0.056), parental knowledge of cancer of cervix (P = 0.483), religion of parents (P = 0.324) and the acceptance of HPV vaccination for their children. There was a statistically significant association between parental willingness to pay for HPV vaccines if not offered free (P = 0.001) with acceptance of vaccination. Vaccine acceptability was associated with positive attitude towards the vaccine (odds ratio [OR] = 4.178; 95% CI, 1.714-10.180; P = 0.002), whereas parental knowledge of HPV, cervical cancer and HPV vaccine did not show significant association with acceptability of HPV vaccination for their children.

Conclusion

Despite poor parental knowledge of HPV infection and cervical cancer, there was high acceptability of HPV vaccination for their children. HPV vaccination was acceptable to parents regardless of educational level or religion. Parents in Jos communities seems to have much faith in preventive vaccines as advertised by the health authorities. Accordingly, efforts should be geared towards ensuring availability, affordability and the provision of basic information regarding HPV vaccination in Northern Nigeria.

Equity impact of HPV vaccination on lifetime projections of cervical cancer burden among cohorts in 84 countries by global, regional, and income levels, 2010-22: a modelling study

Background

While human papillomavirus (HPV) vaccines have been available since 2006, the coverage has varied among countries. Our aim is to analyse the equity impact of HPV vaccination on the lifetime projections of cervical cancer burden among vaccinated cohorts of 2010-22 in 84 countries.

Methods

We used WHO and UNICEF estimates of national immunisation coverage for HPV vaccination in 84 countries during 2010-22. We used PRIME (Papillomavirus Rapid Interface for Modelling and Economics) to estimate the lifetime health impact of HPV vaccination on cervical cancer burden in terms of deaths, cases, and disability-adjusted life years (DALYs) averted by vaccination in their respective countries. We generated concentration indices and curves to assess the equity impact of HPV vaccination across 84 countries.

Findings

The health impact of HPV vaccination varied across the 84 countries and ranged from Switzerland to Tanzania at 2 to 34 deaths, 4 to 47 cases, and 40 to 735 DALYs averted per 1000 vaccinated adolescent girls over the lifetime of the vaccinated cohorts of 2010-22. The concentration index for the distribution of average coverage during 2010-22 among the 84 countries ranked by vaccine impact was 0.33 (95% CI: 0.27-0.40) and highlights the wide inequities in HPV vaccination coverage.

Interpretation

Our findings suggested that countries with a relatively higher cervical cancer burden and thereby a relatively higher need for HPV vaccination had relatively lower coverage during 2010-22. Further, there were significant inequities in HPV vaccination coverage within the Americas, Europe, and Western Pacific regions, and in high- and low-income countries with a pro-advantaged and regressive distribution favouring countries with lower vaccine impact.

The utility of ultrasonographic surveillance in management of a presumed branchial cleft cyst later confirmed HPV-associated oropharyngeal cancer

While branchial cleft cysts are often considered benign pathologies, the literature discusses cases of squamous cell carcinoma (SCC) arising from these cystic lesions as either a primary or metastatic tumor. We illustrate our institutional experience and review the current literature to identify recommendations for best diagnostic, surveillance, and treatment guidelines for SCC identified in a branchial cleft cyst. A 61-year-old male presented with a right sided neck mass, with suspicion of a branchial cleft cyst due to benign findings on fine needle aspiration. Following surgical excision, a focus of SCC was found on surgical pathology. Despite PET/CT and flexible laryngoscopy, no primary tumor was identified prompting routine surveillance every 3 months with cervical ultrasonography and flexible nasolaryngoscopy. Two and a half years following his initial presentation, pathologic right level II lymphadenopathy was detected on ultrasound without evidence of primary tumor. Subsequent transoral robotic surgery with right tonsillectomy and partial pharyngectomy, with right lateral neck dissection revealed a diagnosis of pT1N1 HPV-HNSCC and he was referred for adjuvant chemotherapy and radiation. To our knowledge there are less than 10 cases of confirmed HPV-associated oropharyngeal SCC arising from a branchial cleft cyst. Here we demonstrate the utility of ultrasound as a surveillance tool and emphasize a higher index of suspicion for carcinoma in adult patients with cystic neck masses.

Translation and psychometric evaluation of an instrument to assess the health beliefs of Pakistani mothers regarding human papillomavirus vaccination

Objective

Investigating mothers' health beliefs regarding human papillomavirus (HPV) vaccination is essential for understanding their decisions regarding vaccinating their daughters against HPV. There is no available validated instrument to measure the health beliefs of Pakistani mothers regarding HPV vaccination for their daughters. The purpose of this study was to translate the Human Papillomavirus Vaccination Scale - Health Belief Model (HPVS-HBM) into Urdu and to evaluate the psychometric properties of the translated Urdu version among Pakistani mothers in Hong Kong.

Methods

This was a descriptive correlational study for which a convenience sample of 260 Pakistani women was recruited. The original HPVS-HBM questionnaire was translated from English to Urdu according to Brislin's model. A panel of experts reviewed the translated questionnaire and assessed the content validity of the items and the scale. Face validity was assessed in a sample of five Pakistani mothers, while structural validity was examined by an exploratory factor analysis. Internal consistency and test-retest reliability were assessed to evaluate the reliability of the translated instrument.

Results

The translated questionnaire demonstrated good face validity and content validity (item-level content validity index: 0.83-1.00; scale-level content validity index: 0.89-1.00). Factor analysis of the 22 items in the scale revealed a three-factor structure (perceived susceptibility, perceived severity and perceived benefits), which accounted for 77.66% of the total variance. The translated questionnaire also showed good internal consistency (Cronbach's alpha: 0.93-0.98) and acceptable test-retest reliability (weighted kappa: 0.49-0.96; intra-class correlation coefficient: 0.83-0.93).

Conclusions

The translated Urdu version of the HPVS-HBM demonstrated desirable psychometric properties, indicating that it could be used as a valid and reliable instrument for measuring Pakistani mothers' health beliefs regarding HPV vaccination for their daughters in Hong Kong.

Understanding Factors Affecting Health Providers' Perceptions of Pharmacist Roles in HPV Vaccine Administration

Human papillomavirus (HPV) is a viral infection that sexually active females and males may be exposed to in their lifetime. The HPV vaccine is highly recommended especially among children to protect them before their anticipated exposure to HPV, however, vaccination uptake in Hawai'i remains low. As of 2017, legislation allows pharmacists to vaccinate for adolescent vaccines with the potential to increase access and opportunities for patients to complete the HPV vaccine series. Physicians in Hawai'i were surveyed to examine physicians' awareness of this law, their perceptions of the role of pharmacists, and willingness to send adolescent patients to pharmacies; 137 responses were received and analyzed. Overall, 72% (n=99) of respondents were willing while 28% (n=38) were unwilling to send patients to pharmacies for vaccines. Physicians view pharmacists' role as helpful but have concerns regarding correct administration and tracking doses given. Results show potential for more physician-pharmacist collaborations through further education and trainings for pharmacists and health providers to increase physician referrals for adolescent vaccine services in pharmacies.

Opportunities for cancer prevention at syringe services programs: acceptability of HPV self-sampling and vaccination among people who inject drugs

INTRODUCTION

Despite having a high risk of acquiring sexually transmitted infections, people who inject drugs (PWID) often do not receive recommended HPV screenings due to barriers to healthcare. Guideline-based cervical HPV screening and vaccination can prevent cervical cancer. Low-cost, low-barrier methods for cancer screening and prevention are important for vulnerable communities such as PWID.

METHODS

We examined acceptability of HPV self-sampling at a syringe services program (SSP). Participants with a cervix (n = 49) participated in patient education followed by a survey to assess willingness to perform HPV self-sampling versus standard of care.

RESULTS

59% found self-sampling to be acceptable, citing privacy, ease, and quickness. Among those opting for HPV screening delivered by a provider (n = 16), participants cited concerns about adequate sampling (81%) and test accuracy (75%). Notably, only 18% of participants reported complete HPV vaccination.

CONCLUSION

Cervical HPV self-sampling was acceptable to PWID. SSP-based efforts to provide preventative health services could place tools for cancer screening into the hands of PWID, a need-to-reach community.

Menopausal status induces vaginal dysbiosis in women with human papillomavirus infection

In this study, we examined the difference in the vaginal microbiota of women infected with human papillomavirus (HPV), according to menopausal status. A total of 75 cervicovaginal swab samples from 38 pre- and 37 postmenopausal women with HPV infection were obtained from the Korean HPV cohort. Vaginal microbiota analysis, including microbial diversity and specific bacterial abundances, was performed using 16S rRNA gene sequencing. The mean age of the pre- and postmenopausal women were 29.5 and 55.8 years, respectively (p < 0.0001). Lactobacillus spp. were predominant in both groups; however, a marked decrease was observed in postmenopausal women compared to premenopausal women (44.3% vs. 74.2%). Various anaerobic bacteria also showed a relatively high abundance in the postmenopausal group; Atopobium vagina and Gardnerella vaginalis significantly increased in postmenopausal women. Interestingly, no significant differences in bacterial richness were observed between the two groups. However, significant differences in beta-diversity were observed using the Bray-Curtis (p = 0.001), Generalized UniFrac (p = 0.002), Jensen-Shannon (p = 0.001), and UniFrac algorithms (p = 0.002). Theres results indicate that postmenopausal women with HPV infection exhibited a higher degree of vaginal dysbiosis than premenopausal women. Further, HPV-infected postmenopausal women had increased vaginal microbial diversity, characterized by an increase in anaerobic bacteria and concomitant depletion of Lactobacillus spp.
