To evaluate the efficacy and safety of reducing target volume in definitive radiotherapy for HPV-associated tonsil cancer.A single-institution cohort of 90 patients with human papillomavirus (HPV)-associated tonsil cancer who received definitive radiotherapy with a 5-mm expansion from the gross tumor volume to clinical target volume between 2008 and 2019 were included. The overlapping volume of initial planning target volume and the recurrent tumor was calculated and categorized as one of three failure types: in-field: ≥95%; marginal-field: 50%-94%; and out-field:50%.With a median follow-up of 59.4 months, the 3-year and 5-year local control rates were 94.4% and 92.8%, respectively. A total of seven local failures were identified, of which 4 (4.4%) were in-field, 2 (2.2%) were marginal-field, and 1 (1.1%) was out-field. Grade 3 acute and late toxicities developed in 30 (33.3%) and 5 (5.6%) patients, respectively.Reducing target volume could be an alternative option for selected patients with HPV-associated tonsil cancer.

Previous human papillomavirus (HPV) and HPV vaccine knowledge scales have focused on young adults in the vaccination catch-up age range or parents of vaccine eligible adolescents. Previous scales are not specific to the new guidelines for HPV vaccination in mid-adults. The study aimed to develop and validate a mid-adult HPV vaccine knowledge scale informed by the latest vaccine recommendations.Self-reported data were collected using a cross-sectional survey of adults aged 27 to 45 years with no history of HPV vaccination (n = 706). Exploratory and confirmatory factor analyses identified latent constructs in a 13-item mid-adult HPV vaccine knowledge scale. Sociodemographic differences in the HPV vaccine knowledge were also assessed.The mean of correct responses across all items was 5.9 (SD, 2.8; range, 0-13). Exploratory and confirmatory factor analyses revealed a 3-factor structure best explained the data with a good construct validity and reliability. The first factor contained 6 items about HPV infection, the second factor contained 3 items about HPV prevention through vaccination, and the third factor contained items about HPV vaccination misinformation. Analysis of variance and t test found significant group level differences in knowledge among sex, race, educational level, annual income, health insurance, and marital status.Our study supports the use of a knowledge scale for US mid-adults to assess HPV and HPV vaccination knowledge because the patient requires some baseline knowledge of this recommendation to discuss the vaccine with their health care provider. The mid-adult HPV vaccine knowledge scale can measure basic HPV knowledge important to informed decision making.

Background: Among women whose cervical specimens tested positive for high-risk human papillomaviruses (hrHPV) via the Hybrid Capture 2 assay in the Canadian Cervical Cancer Screening Trial (CCCaST), we assessed hrHPV genotype concordance between BD Onclarity HPV Assay and Roche's Linear Array, overall and stratified by hrHPV viral load. We also evaluated the performance of cytology, cytology combined with hrHPV genotyping (Onclarity assay) for HPV16/18 and non-HPV16/18 types, and hrHPV genotyping triage strategies for the detection of cervical intraepithelial neoplasia grade 2 or 3 and worse (CIN2+/CIN3+). Methods: Standard measures (expected agreement, agreement, and κ values) were used to compare Onclarity to the reference test, Linear Array. Twenty-four triage strategies were evaluated by calculating their sensitivities, specificities, and positive and negative predictive values for CIN2+ and CIN3+ detection. Results: Among 734 hrHPV+ samples tested, there was near perfect concordance irrespective of viral load between the Onclarity and Linear Array assays for the individual genotypes [human papillomaviruses (HPV) 16, 18, 31, 45, 51, 52] by Onclarity (κ values ranged from 0.92–0.98). Strategies with adequate specificity (>75%) and the highest sensitivities to detect CIN3+ among 617 women positive for hrHPV, were positivity to HPV16 and/or 31 (Sensitivity: 65.2%, Specificity: 76.9%) and HPV16 and/or 18 (Sensitivity: 58.7%, Specificity: 81.6%). Conclusions: While confirming the importance of HPV16, we found that HPV31 was comparable with HPV18 for the detection of CIN2/3+ in the triage of women positive for hrHPV. Impact: HPV31 may be an important genotype in the triage of women positive for hrHPV.

Because of the lack of data and studies on metastatic non-oropharyngeal head and neck cancer (non-OP HNC), the role of human papillomavirus (HPV) status in non-OP HNC with distant metastasis is still unclear. Therefore, we conducted a study to explore the differences in metastatic patterns, survival and treatment responses in metastatic non-OP HNC based on HPV status.A total of 333 metastatic non-OP HNC patients were diagnosed from 2010 to 2016 in the Surveillance, Epidemiology and End Results (SEER) database. The chi-square test and Fisher's exact test were used to make comparisons for categorical variables. The Kaplan-Meier method and Cox regression analyses were used to analyse survival.HPV status was a significant prognostic variable for patients with non-OP HNC with distant metastasis. HPV- patients were more likely to have distant metastasis and worse prognosis and treatment response than HPV+ patients. Only chemotherapy was an independent prognostic factor for HPV+ patients with distant metastasis, while chemotherapy and radiotherapy were both independent prognostic factors for HPV- patients with distant metastasis. The treatment response was associated with the metastatic pattern in both HPV+ and HPV- populations and showed significant differences based on HPV status and metastatic pattern.For non-OP HNC with distant metastasis, HPV+ and HPV- patients formed two different cohorts in terms of metastatic pattern, survival and treatment. Therefore, it is helpful to classify metastatic non-OP HNC into different groups to choose appropriate treatment strategies according to HPV status and metastatic pattern.

Determining human papillomavirus (HPV) status in oropharyngeal squamous cell carcinoma can have a significant impact on treatment and clinical outcomes. Because fine-needle aspiration (FNA) is typically an initial diagnostic modality in a patient workup for primary or suspected metastatic disease, immunostaining for p16 on FNA material is a promising option to determine HPV tumor status, possibly avoiding biopsies or excisions. In this study, the authors investigated the possibility of using alcohol-fixed smears as a reliable alternative for reporting p16 status.Twenty HPV-associated tumors and 20 non-HPV-associated tumors were identified using the gold-standard histologic cutoff for positivity of ≥70% strong nuclear and cytoplasmic staining. Matched FNA specimens were identified for comparison staining, and a positive p16 result was rendered on a single aspirate smear using the same cutoff of ≥70%.On alcohol-fixed cytology smears, 16 of 20 (80%) HPV-associated tumors showed positive p16 staining in ≥70% tumor cells. Four cases showed lower level (30%-60%) nuclear and cytoplasmic staining. Nineteen of 20 (95%) non-HPV-associated tumors showed no or minimal p16 staining (0%-10%), and 1 case had a p16-equivocal cytology result.The authors performed immunocytochemical validation for p16 using alcohol-fixed smears and observed promising results, offering this technique as a potential alternative to formalin-fixed tissue in the appropriate clinical context. By using a positive staining cutoff of ≥70%, this technique offers 80% sensitivity and 95% specificity for detecting HPV-associated tumors. Although it was not performed in the current study, HPV-specific testing on available formalin-fixed, paraffin-embedded tissue should be considered in cases with equivocal or negative p16 staining.

HPV68 is a common HR-HPV, its persistent infection is closely related with the occurrence of cervical cancer. In this study, 2939 (27.60%, 2939/10650) positive samples were detected, and 174 (5.92%, 174/2939) were HPV68. 150 HPV68 E6-E7 were successful sequenced, 4 non-synonymous mutations were detected in E6, and E7 were 12. N133S non-synonymous mutations of HPV 68 E6 and C67G, T68 A/M of HPV68 E7 are E6, E7 positive selection sites, they all located in the key domains and major motifs of E6/E7 protein, the above amino-acid substitutions changed the protein structure, disturbed the interaction with other protein or cellular factors and make a difference in epitopes affinity, may affect the pathogenicity and adaptability of HPV68 to the environment. The enrichment of HPV68 data is of great significance for understanding the inherent geographical and biological differences of HPV68 in China.

Background The introduction of primary HPV screening has doubled the number of colposcopy referrals because of the direct referral of HPV-positive women with a borderline or mild dyskaryosis (BMD) cytology (ASC-US/LSIL) triage test. Further risk-stratification is warranted to improve the efficiency of HPV-based screening. Methods This study evaluated the discriminative power of FAM19A4/miR124-2 methylation, HPV16/18 genotyping and HPV16/18/31/33/45 genotyping in HPV-positive women with BMD (n = 294) in two Dutch screening trials. Absolute CIN3+ risks and colposcopy referrals within one screening round were calculated. Results Methylation analysis discriminated well, yielding a CIN3+ risk of 33.1% after a positive result and a CIN3+ risk of 9.8% after a negative result. HPV16/18 and HPV16/18/31/33/45 genotyping resulted in a 27.6% and 24.6% CIN3+ risk after a positive result, and a 13.2% and 9.1% CIN3+ risk after a negative result. Colposcopy referral percentages were 41.2%, 43.2%, and 66.3% for FAM19A4/miR124-2 methylation, HPV16/18 and HPV16/18/31/33/45 genotyping, respectively. The CIN3+ risk after a negative result could be lowered to 2.8% by combining methylation and extended genotyping, at the expense of a higher referral percentage of 75.5%. Conclusion The use of FAM19A4/miR124-2 methylation and/or HPV genotyping in HPV-positive women with BMD can lead to a substantial reduction in the number of direct colposcopy referrals.

Religion is a complex and sociocultural driver of human papillomavirus (HPV) vaccination decisions, but its exact role has been mixed/unclear. We used a cross-sectional study of 342 Christian parents to examine the associations between the three domains of religiosity (organizational, non-organizational, and intrinsic) and the intention to (i) seek HPV information and (ii) receive the HPV vaccine. Organizational religiosity was the only domain that was positively associated with information-seeking intention regardless of the type of covariates included. Mixed findings in the association between religiosity and HPV vaccination decisions may depend on the religiosity domain being assessed.

BackgroundThe aim of this study was to determine individual-level, partner-level, and sexual networking factors associated with vaccine- and non-vaccine-type human papillomavirus (HPV) in young women, by vaccination status.MethodsSexually experienced women 13 to 26 years old (n = 784) completed a survey and were tested for 36 HPV genotypes. We determined factors associated with 4-valent vaccine-type HPV (HPV-6, HPV-11, HPV-16, HPV-18) and non-vaccine-type HPV among vaccinated and unvaccinated women, using univariable and multivariable logistic regression models.ResultsParticipants' mean age was 19.2 years, 77.7% had received ≥1 vaccine dose, and 7.7% were positive for vaccine-type HPV (HPV-6, HPV-11, HPV-16, and/or HPV-18). Factors associated with vaccine-type HPV in vaccinated women included gonorrhea history (adjusted odds ratio [AOR], 2.71), new female sex partner(s) (AOR, 4.79), age at vaccination (≥15 vs.

High-risk genotypes of human papillomaviruses (HPVs) are directly implicated in various abnormalities associated with cellular hyperproliferation, including cervical cancer. E6 is one of two oncoproteins encoded in the HPV genome, which recruits diverse PSD-95/Dlg/ZO-1 (PDZ) domain-containing human proteins through its C-terminal PDZ-binding motif (PBM) to be degraded by means of the proteasome pathway. Among the three PDZ domain-containing protein tyrosine phosphatases, protein tyrosine phosphatase non-receptor type 3 (PTPN3) and PTPN13 were identified to be recognized by HPV E6 in a PBM-dependent manner. However, whether HPV E6 associates with PTPN4, which also has a PDZ domain and functions as an apoptosis regulator, remains undetermined. Herein, we present structural and biochemical evidence demonstrating the direct interaction between the PBM of HPV16 E6 and the PDZ domain of human PTPN4 for the first time. X-ray crystallographic structure determination and binding measurements using isothermal titration calorimetry demonstrated that hydrophobic interactions in which Leu158 of HPV16 E6 plays a key role and a network of intermolecular hydrogen bonds sustain the complex formation between PTPN4 PDZ and the PBM of HPV16 E6. In addition, it was verified that the corresponding motifs from several other high-risk HPV genotypes, including HPV18, HPV31, HPV33, and HPV45, bind to PTPN4 PDZ with comparable affinities, suggesting that PTPN4 is a common target of various pathogenic HPV genotypes.

The human papillomavirus (HPV) vaccine is one of the most cost-effective public health measures for preventing cervical cancer and other HPV-related diseases. However, the vaccine uptake in many countries remains suboptimal. This cross-sectional study aimed to assess the knowledge and awareness of parents towards HPV, related diseases, and HPV vaccines, as well as to examine the effect of brief educational information on parents' vaccine acceptability. We used a structured interviewer-administered questionnaire to collect information from 227 outpatient visitors to a healthcare center who had children under the age of 19 years. We asked parents again about their acceptance of HPV vaccines after being provided brief educational information. Of all the parents, 43% were aware of HPV and related diseases, and 59% of those had sufficient knowledge regarding HPV while 45% of them reported that they were aware of HPV vaccines. Being Northern Cypriot was a predictor of having good knowledge, whilst being a female, having a higher education level, being 35 years or older, and being employed were the significant predictors of having greater awareness of HPV and related diseases. The HPV vaccine acceptance of the parents increased substantially in all sociodemographic groups after the provision of the educational information. The findings demonstrated that the vaccination rates of children of parents who have insufficient knowledge and awareness of HPV and vaccines are also very low. Effective educational interventions based on the specific sociodemographic characteristics of the patients should be given a stronger focus to improve vaccine acceptability among this population.

Cervical cancer is the third most frequent cancer in Chinese women aged 15���44 years old. Human papillomavirus (HPV) is recognized as the main etiologic agent of cervical carcinomas. This study aims to better understand the natural history of HPV infections in Chinese women aged 18���25 years. Data from 3,025 control arm women (AS04-HPV-16/18 vaccine trial) were analyzed to assess the probability of progression or clearance from a 6-month persistent infection (6MPI) to a cervical intraepithelial neoplasia grade 2 or greater (CIN2+), and the association with clinical determinants. Data were analyzed using univariate and multivariable Cox models. A total of 1,324 women with 3,814 HPV infections were included, and 65.7% of the women had at least one 6MPI. Among those 6MPI, 5.0% progressed to CIN2+, while 61.0% cleared within 6 months. The risk of progression from 6MPI to CIN2+ was substantially higher for oncogenic versus non-oncogenic HPV types. Oncogenic HPV infections showed lower clearance and higher risk to progress to CIN2 +. These findings observed in a population of Chinese women, confirmed previous findings from multinational studies. The PATRICIA and AS04-HPV-16/18 vaccine trials are registered at ClinicalTrials.gov (NCT00779766 and NCT00122681).

Background Although cervicovaginal microbiome has been associated with cervical human papillomavirus (HPV) infection, little is known regarding the association of oral microbiome with oral HPV, a cause of oropharyngeal cancer. Methods A cross-sectional analysis of 495 participants from the Men and Women Offering Understanding of Throat HPV study was conducted. 16S rRNA gene amplicon sequencing was performed on saliva samples. HPV DNA in oral rinse samples was tested. Associations of oral microbiome diversity, taxon abundance, and predicted functional pathways with oral HPV were assessed, adjusting for age, race/ethnicity, education, human immunodeficiency virus, current smoking, and sequencing batch. Results Participants with oral HPV (n = 68) compared with those without HPV had similar oral microbiome alpha-diversity yet different beta-diversity (Bray-Curtis distance for bacterial taxa, P = .009; functional pathways, P = .02). Participants with oral HPV had higher abundance of Actinomycetaceae, Prevotellaceae, Veillonellaceae, Campylobacteraceae, Bacteroidetes, and lower abundance of Gemellaceae (false discovery rate Conclusions Our findings suggest a shift in oral microbiome community structure, composition, and functional potential between individuals with and without oral HPV.

The purpose of this study was to test the psychometric properties of a brief attitudes and beliefs toward human papillomavirus (HPV) vaccination instrument in college students.Cross-sectional, observational study.Eighty-six nursing students.The Attitudes and Beliefs Toward Human Papillomavirus Vaccination was used to test the reliability (Cronbach's alpha), homogeneity (item-analyses), and validity (factor analysis and correlations).The reliability of this 8-item instrument was supported by a Cronbach's alpha of .854. Item homogeneity was supported by coefficients for all items .30. Convergent validity was supported by significant correlations of attitudes and beliefs assessed by this instrument to attitudes, subjective norm, and perceived behavioral control assessed by different instruments (all ps .001). Construct validity was supported by exploratory and confirmatory factor analyses (all factor loadings ≥ .40). Predictive validity was supported by a significant relationship of attitudes and beliefs to completion of the vaccination (p .001).The Attitudes and Beliefs Toward Human Papillomavirus Vaccination Questionnaire was a reliable and valid instrument. This short instrument can be used to assess and improve attitudes and beliefs toward HPV vaccination, and, in turn, to facilitate the completion of the vaccination.

Introduction: Little is known about human papillomavirus (HPV) information sources and communication among Chinese students attending U.S. colleges. We assessed information sources and communication about HPV and HPV vaccines among this population. Methodology: A cross-sectional design with 449 participants was conducted by using a questionnaire and snowball sampling. Summary statistics and multiple logistic regression were used. Results: The most common sources of HPV information included the internet and friends. Communication about HPV occurred most frequently among friends, family, and health professionals. Those who had better HPV knowledge and attitudes and were vaccinated against HPV were more likely to use internet, friends, family, and health professionals as their information sources. Discussion: Because the internet, friends, and families are likely sources for HPV information and communication, future internet-based culturally appropriate education should offer information not only to Chinese students but also to their social circles. Cultural beliefs may affect HPV prevention and should be examined.

Cervical clear cell carcinoma (CCC) is a rare human papillomavirus-independent adenocarcinoma. While recent studies have focused on gastric-type endocervical adenocarcinoma (GTA), little is known about CCC. A total of 58 (CCCs) were collected from 14 international institutions and retrospectively analyzed using univariable and multivariable methods and compared with 36 gastric-type adenocarcinomas and 173 human papillomavirus-associated (HPVA) endocervical adenocarcinoma (ECA) regarding overall survival (OS) and recurrence-free survival (RFS). Most cases were FIGO stage I (72.4%), with Silva C pattern of invasion (77.6%), and the majority were treated with radical surgery (84.5%) and adjuvant therapy (55.2%). Lymphovascular invasion was present in 31%, while lymph node metastasis was seen in 24.1%; 10.3% were associated with abdominopelvic metastases at the time of diagnosis; 32.8% had recurrences, and 19% died of disease. We did not find statistically significant differences in OS and RFS between CCC and GTA at 5 and 10 years (P=0.313 and 0.508, respectively), but there were significant differences in both OS and RFS between CCC and HPVA ECA (P=0.003 and 0.032, respectively). Also, OS and RFS in stage I clear cell and GTA were similar (P=0.632 and 0.692, respectively). Multivariate analysis showed that OS is influenced by the presence of recurrence (P=0.009), while RFS is influenced by the FIGO stage (P=0.025). Cervical CCC has poorer outcomes than HPVA ECA and similar outcomes to human papillomavirus-independent GTA. Oncologic treatment significantly influences RFS in univariate analysis but is not an independent prognostic factor in multivariate analysis suggesting that alternative therapies should be investigated.

Development of malignancy is a pending threat for patients with inflammatory bowel disease (IBD). Aim of this study was to analyze cervical dysplasia and infection with human papilloma virus (HPV) in patients with IBD.This was a prospective, single center cohort study in Germany. Consecutive IBD patients admitted to the Department of Gastroenterology were sent to Gynecology, where a questionnaire was answered and gynecological examinations including a smear for cytology and HPV were taken. Participants of a general screening program constituted controls. Descriptive statistics, 95% confidence intervals and odds ratios were calculated.A total of 101 patients were recruited of which 99 patients participated. Analysis showed a significant (p = 0.05) difference between the prevalence of abnormal smears in patients with (22%) and without (6%) immunosuppressive therapy, while the latter had cervical abnormalities comparable with healthy controls (5%). All immunosuppressants showed similarly high risks for abnormal smear results. Only 11/99 (11%) patients had positive high-risk HPV tests, which is comparable with general population.The prevalence of abnormal cervical smears is higher in IBD patients compared to healthy individuals, but the difference is confined to patients with IBD and immunosuppressive therapy. Annual screening is advisable.

Introduction: The oncogenic human papillomaviruses (HPV) types 16 and 18 contribute to more than 73% cases of all HPV-related cancers and commonly affect the anogenital and head and neck region, with rapidly rising incidence rates of HPV-related oropharyngeal squamous cell carcinomas (OPSCC). HPV vaccination has the potential to decrease the burden of HPV-related disease, but vaccination rates remain low in many countries. We investigated the level of awareness of HPV, and HPV-OPSCC in particular, in a representative sample of the German population. Materials and Methods: As part of an online, population-based survey, an electronic questionnaire was administered to a representative sample of 1,095 adult individuals with a specific emphasis on awareness of HPV, transmission, and indicator symptoms of oropharyngeal cancer. Statistical analysis of levels of awareness and relation of these to age, gender, and socioeconomic background were conducted using the IBM SPSS Statistics Version 25.0. Results: 699/1,095 (63.8%) subjects had never heard of HPV. Of the subjects with awareness for HPV, 210 knew that HPV could be transmitted during sex (58.3%) and 138 recognized HPV as a risk factor for OPSCC (14.2%), unrelated to gender (p = 0.357), educational status (p = 0.581), or family status (p = 0.719). 416 subjects knew that a preventive vaccine against HPV existed (44.9%). Women were significantly more aware of HPV (34.2% vs. 22.8%, p < 0.001) and the vaccination (56.4% vs. 32.7%, p < 0.001) as were men. Younger individuals (age group 25–34) were significantly more aware of HPV (p < 0.001), likely as they were offered and/or had received the HPV vaccination. There was no regional variation of HPV awareness within the German state (p = 0.051). Conclusion: Here we demonstrate a significant lack of awareness of HPV and HPV vaccination in a representative sample of the German population. Levels of awareness of the link of HPV and oropharyngeal cancer are particularly low, bearing in mind that this cancer is commonly affecting men and incidence rates are rapidly rising in many European countries and the USA. Awareness programs and further education are required to tackle the low awareness rates and increase the uptake of the vaccination program not only in Germany, but also worldwide.

Bacterial vaginosis (BV) is a highly prevalent condition that is associated with adverse health outcomes. It has been proposed that BV’s role as a pathogenic condition is mediated via bacteria-induced inflammation. However, the complex interplay between vaginal microbes and host immune factors has yet to be clearly elucidated. Here, we develop molBV, a 16 S rRNA gene amplicon-based classification pipeline that generates a molecular score and diagnoses BV with the same accuracy as the current gold standard method (i.e., Nugent score). Using 3 confirmatory cohorts we show that molBV is independent of the 16 S rRNA region and generalizable across populations. We use the score in a cohort without clinical BV states, but with measures of HPV infection history and immune markers, to reveal that BV-associated increases in the IL-1β/IP-10 cytokine ratio directly predicts clearance of incident high-risk HPV infection (HR = 1.86, 95% CI: 1.19-2.9). Furthermore, we identify an alternate inflammatory BV signature characterized by elevated TNF-α/MIP-1β ratio that is prospectively associated with progression of incident infections to CIN2 + (OR = 2.81, 95% CI: 1.62-5.42). Thus, BV is a heterogeneous condition that activates different arms of the immune response, which in turn are independent risk factors for HR-HPV clearance and progression. Clinical Trial registration number: The CVT trial has been registered under: NCT00128661., Here, Burk et al. develop an algorithm to diagnose bacterial vaginosis (BV) using the 16S rRNA gene, called molBV, which they use to profile the inflammatory landscape of BV and predict progression of human papillomavirus infection to cervical pre-cancer.

IMPORTANCE: Despite availability of safe and effective human papillomavirus (HPV) vaccines, vaccination uptake remains low in the U.S. Research examining the impact of neighborhood socioeconomic status on HPV vaccination may help target interventions. OBJECTIVE: To examine the association between area deprivation and HPV vaccine initiation and completion. DESIGN, SETTING, PARTICIPANTS: Retrospective cohort study of individuals aged 11–18 years residing in the upper Midwest region. Receipt of HPV vaccination was examined over a three-year follow-up period (01/01/2016–12/31/2018). MAIN OUTCOMES AND MEASURES: Outcomes of interest were initiation and completion of HPV vaccination. Demographic data were collected from the Rochester Epidemiology Project (REP). Area-level socioeconomic disadvantage was measured by calculating an Area Deprivation Index (ADI) score for each person, a measure of socioeconomic disadvantage derived from American Community Survey data. Multivariable mixed effect Cox proportional hazards models were used to examine the association of ADI quartiles (Q1-Q4) with HPV vaccine series initiation and completion given initiation. RESULTS: Individuals residing in census block groups with higher deprivation had significantly lower likelihood of HPV vaccine initiation (Q2: HR=0.91, 0.84–0.99 Q3: HR= 0.83, 0.76–0.90; Q4: HR=0.84, 0.74–0.96) relative to those in the least-deprived block groups (Q1). Similarly, those living in block groups with higher deprivation had significantly lower likelihood of completion (Q2: HR=0.91, 0.86–0.97; Q3: HR= 0.87, 0.81–0.94; Q4: HR=0.82, 0.74–0.92) compared to individuals in the least-deprived block groups (Q1). CONCLUSIONS AND RELEVANCE: Lower probability of both HPV vaccine-series initiation and completion were observed in areas with greater deprivation. Our results can inform allocation of resources to increase HPV vaccination rates in our primary care practice and provide an example of leveraging public data to inform similar efforts across diverse health systems.

Background: Head and neck cancer (HNC) develops due to a number of risk factors, including infection of Human Papillomavirus (HPV). The genetic predisposition also plays an important role in deregulating different signaling pathways including the NF-KB pathway. Certain polymorphisms are reported to affect the NF-kB pathway genes. Objectives: The present research was conducted to study the association of HPV with NF-KB1 (p50) gene polymorphisms in HNC patients of the Pakistani population. Methods: Genomic DNA from HNC tumors samples was extracted using the Exgene SV DNA extraction Kit. Allele-specific PCR and direct sequencing were done for analysis of NF-κB1 SNPs 94ins/del (rs28362491), rs1598858 and rs4648068. Results: The genotypes AGrs1598858, AGrs4648068 and GGrs4648068 were associated with significantly increased risk of head and neck cancer in studied population. Furthermore the HNC cases with genotypes AGrs1598858 and GGrs4648068 displayed growing risk of HPV related cancers. Promotor region SNP 94ins/del (rs28362491) was not detected in studied population. Tobacco use, lymph nodes involvement and poorly differentiated tumors were positively associated with HPV induced cancers. Conclusion: It is the first comprehensive study from Pakistan, to evaluate the polymorphic variants of NF-κB1. Genotypes AGrs4648068, GGrs4648068, and AGrs1598858 of NF-κB1 gene are associated with increased risk of head and neck cancers in the studied HPV infected Pakistani population. It can be concluded that HPV infection, involvement of lymph nodes and tobacco use can act synergetic and add up in modulating HPV induced HNC with intronic SNPs of NF-κB1 gene in Pakistani population.

The study aimed to compare the performance of human papillomavirus (HPV)-based strategies to cytology for detecting cervical intraepithelial neoplasia grade 3 or worse (CIN3+) in routine program in China. The study included 50,434 women ages 30–64 years from January 2015 to December 2019, to assess four strategies: cytology with HPV triage (strategy 1), primary HPV testing with reflex cytology (strategy 2), primary HPV testing with HPV-16/18 genotyping and reflex cytology for non-16–18 high-risk HPV genotypes (strategy 3), and co-testing (strategy 4). The main outcomes were sensitivity for CIN3+ and colposcopy referral rate. Overall, the rates of HPV positivity and cytologic abnormality were 7.0% [95% confidential interval (CI), 6.8–7.2] and 3.5% (95% CI, 3.3–3.6], respectively. The sensitivity for CIN3+ were 88.5% for strategy 4, 83.2% for strategy 3, 64.6% for strategy 1, and 60.1% for strategy 2. The relative sensitivity of strategy 4 and strategy 3 compared with strategy 1 for detecting CIN3+ were 1.38 (95% CI, 1.24–1.54) and 1.29 (95% CI, 1.14–1.46), respectively. The colposcopy referral rates of strategies 4 and 3 were significantly higher than that of strategy 1 (2.4% and 2.2% vs. 1.4%, P < 0.001). In conclusion, co-testing and primary HPV testing with HPV-16/18 genotyping and reflex cytology improved the sensitivity for CIN3+ compared with cytology but increased the colposcopy referral rate. Long-term negative predicted value for HPV-negative women should be studied to determine the screening interval. Our study provides further evidence to the introduction of HPV-based strategies in China. Prevention Relevance: Both co-testing and primary HPV testing with HPV-16/18 genotyping and reflex cytology triage provided higher sensitivity for detecting CIN3+; however, the number of colposcopy referrals also increased compared with cytology in a routine program. It has great public health implications for the introduction of HPV-based screening strategies in China.

To compare all available accuracy data on screening strategies for identifying cervical intraepithelial neoplasia grade ≥ 2 in healthy asymptomatic women, we performed a systematic review and network meta-analysis. MEDLINE and EMBASE were searched up to October 2020 for paired-design studies of cytology and testing for high-risk genotypes of human papillomavirus (hrHPV). The methods used included a duplicate assessment of eligibility, double extraction of quantitative data, validity assessment, random-effects network meta-analysis of test accuracy, and GRADE rating. Twenty-seven prospective studies (185,269 subjects) were included. The combination of cytology (atypical squamous cells of undetermined significance or higher grades) and hrHPV testing (excepting genotyping for HPV 16 or 18 [HPV16/18]) with the either-positive criterion (OR rule) was the most sensitive/least specific, whereas the same combination with the both-positive criterion (AND rule) was the most specific/least sensitive. Compared with standalone cytology, non-HPV16/18 hrHPV assays were more sensitive/less specific. Two algorithms proposed for primary cytological testing or primary hrHPV testing were ranked in the middle as more sensitive/less specific than standalone cytology and the AND rule combinations but more specific/less sensitive than standalone hrHPV testing and the OR rule combination. Further research is needed to assess these results in population-relevant outcomes at the program level.

Background The Alphapapillomavirus 9 (α-9 HPV) is a member of the Alphapapillomavirus genus and Papillomaviridae family. These viruses are almost all carcinogenic HPV, which is closely related to 75% of invasive cervical cancer worldwide, and has a high prevalence in Sichuan. The carcinogenic function is mainly realized by its E6 oncoprotein. Methods Cell samples were collected by cervical scraped for HPV detecting and typing. HPV-16, HPV-31, HPV-33, HPV-52, HPV-58 5 α-9 genus HPV subtype positive samples were selected, their E6 gene was sequenced and analyzed. The positive selection sites of HPV E6 genes were estimated by PAML 4.8 server. The secondary and tertiary structure of E6 protein were predicted by PSIPred and Swiss-model. The T-cell antigen epitopes of E6 protein were predicted by IEDB. Results α-9 HPV has a high prevalence in Sichuan, China. From 2012 to 2017, 18,067 cell cervical samples were collected, and 3135 were detected with α-9 HPV infection. Among which, 250 cases HPV-16 E6, 96 cases HPV-31 E6, 216 cases HPV-33 E6, 288 cases HPV-52 E6 and 405 cases HPV-58 E6 were successfully amplified, 17, 6, 6, 13, and 4 non-synonymous nucleotide mutations were respectively detected in HPV-16, 31, 33, 52, and 58 E6, 7 positive selection sites of α-9 HPV E6 were selected out (D32E of HPV-16 E6, K35N, K93N and R145I of HPV-33 E6, K93R of HPV-52 E6, K93N and R145K of HPV-58 E6). The structure and antigen epitopes of E6 protein with amino acid substitution differ from those of wild-type E6 protein, especially for the mutation located in the E6 positive selection site. Conclusions HPV E6 nucleotide non-synonymous mutation in the positive selection site influence the protein structure and decrease the antigen epitopes affinity of the E6 protein overall, making it more difficult for the HPV-infected cells to be detected by the immune system, and enhancing the HPV adaptability to the environment. Mutations influence the validity of HPV clinical diagnostic probes, the polymorphism analysis of α-9 HPV E6 enrich the data of HR-risk HPV in Sichuan China, and the detection probes designed with the polymorphism data in mind can improve the efficiency of clinical detection; Mutations influence epitopes affinity, the association of E6 polymorphism and epitope affinity can improve the design of therapeutic vaccine with good immunity and high generality antigen epitope; The above study all provide a good theoretical basis for the prevention and treatment of HPV-related diseases.

Introduction: The aim of this study was to identify early changes in the Wnt/beta-catenin signaling pathway in high-risk human papillomavirus (HPV) infected cervicovaginal cells and to correlate these changes with cell proliferation, apoptosis, and autophagic processes. Methods: We evaluated 91 cervicovaginal smears of women with (n = 41) and without (n = 50) HPV-DNA. Smears were stained against beta-catenin, c-myc, secreted frizzled-related protein 4 (sFRP4), cleaved caspase-3, and the autophagy markers Beclin-1 and light chain 3B. In addition, sFRP-1, -2, -3, -4, -5 mRNA levels were determined by quantitative reverse transcription-PCR in primary keratinocytes and FaDu cells expressing HPV16-E6, -E7, or -E6E7. Results: Our data indicated that the Wnt/beta-catenin signaling is activated in HPV (+) cervicovaginal cells that can already be detected in cells with no obvious changes in cellular morphology (HPV [+]/cyto [−]). These cells also had significantly higher sFRP4 levels when compared to HPV-negative samples. In primary keratinocytes, sFRP4 was found to be absent and sFRP1 and sFRP2 to be repressed in the presence of HPV16-E6 and E7. Interestingly, sFRP4 is expressed in FaDu cells and can be upregulated in the presence of E6E7. Curiously, SFRP4 expression correlated with an increase in the level of autophagic markers in HPV (+)/cyto (−) smears. Conclusion: In conclusion, the activation of the Wnt/beta-catenin signaling pathway and upregulation of sFRP4, paralleled by an activation of the autophagic pathway may represent predisposing cellular factors early after HPV infection which need to be further determined in larger study.

Since human papillomavirus vaccine introduction, incidence rates of cervical precancers have decreased; however, the vaccine's impact on noncervical anogenital precancers has not been shown. These precancers are identified opportunistically and are not collected routinely by most cancer registries.This study examined the incidence rates of high-grade (intraepithelial lesions grade 3) vulvar, vaginal, and anal precancers among persons aged 15-39 years using 2000-2017 data from select cancer registries covering 27.8% of the U.S. population that required reporting of these precancers. Trends in incidence rates were evaluated with Joinpoint regression. Analyses were conducted in 2020.High-grade vulvar precancer rates declined by 21.0% per year after human papillomavirus vaccine introduction among females aged 15-19 years. In addition, high-grade vaginal precancer rates declined by 19.1% per year among females aged 15-29 years after human papillomavirus vaccine introduction. Compared with that in the prevaccine period when high-grade anal precancer rates were increasing, anal precancer rates after human papillomavirus vaccine introduction were stable among females aged 15-29 years and among males aged 30-39 years. Among males aged 15-29 years, the rates increased over the entire period but less so after human papillomavirus vaccine introduction.Opportunistically-detected high-grade vulvar and vaginal precancers among females aged 15-29 years decreased and anal precancers stabilized in years after the introduction of the human papillomavirus vaccine, which is suggestive of the impact of the vaccine on noncervical human papillomavirus cancers.

Human papillomavirus (HPV) is responsible for a multitude of lesions with high psychosocial burden. The "HPV Impact Profile" (HIP) questionnaire is one of the first and most specific tools evaluating the emotional impact of HPV. This study aimed to translate this questionnaire into Arabic and to validate it, in a sample of Lebanese female patients.The HIP questionnaire was translated to Arabic. It was then administered to 118 Lebanese women infected with HPV or screened for HPV-associated lesions, in parallel with the Hospital Anxiety and Depression Scale questionnaire. The psychometric properties of the questionnaire were studied in our sample population.The internal consistency of the HIP questionnaire was weak as Cronbach α coefficients of most of the domains were low. The study of the composite matrix resulted in the improvement of the internal consistency after the elimination of some items. Moreover, the "adapted domains" were created by reverse-scoring items with positive implications.The composite reliability and the average variance extracted of all the domains were analyzed. Analysis of discriminate validity through heterotrait-monotrait ratio of correlation ratio analyses of corresponding Hospital Anxiety and Depression Scale domains was also performed along with reliability analysis. There results were satisfying for the adapted domains.The adapted domains of the 27 items questionnaire with reverse scoring of 8 items presented with good psychometric properties, allowing their use in clinical trials and in clinical practice.

Human papillomavirus (HPV) infections are associated with cervical cancer and other anogenital cancers. Despite progresses in HPV vaccination and screening, these cancers still show high incidence and mortality, requiring improved prognostic markers and tailored therapies. This review addresses the role of Matrix metalloproteinases (MMPs) in HPV-induced cancers and the modulation of MMP expression by HPV oncoproteins. Scientific literature indexed in PubMed and ScienceDirect about Human papillomavirus modulates matrix metalloproteinases was retrieved and critically analyzed, to obtain an overview of expression patterns and their implications for carcinogenesis and patient prognosis. Matrix metalloproteinases such as MMP1, MMP9 and MMP13 have been associated with patient prognosis in HPV-induced cancers and play a major role in the degradation of the extracellular matrix, tumor invasion and metastasis. The HPV E2 and E7 oncoproteins regulate MMP expression via AKT, MEK/ERK and AP-1 signaling among other mechanisms. Increased expression of MMPs is associated with cancer progression and poor prognosis in multiple HPV-induced cancers, suggesting their potential use as prognostic markers. The identification of specific signaling pathways that mediate MMP regulation by HPV is essential for developing efficient new cancer therapies.

Contains fulltext : 291088.pdf (Publisher’s version ) (Open Access) OBJECTIVE: Cytology performed directly on hrHPV-positive self-samples (reflex cytology) is feasible and for women with abnormal cytology, an additional cytology test at the general practitioner could be omitted. The aim of this study is to assess the added value of digital imaging (ThinPrep® Imaging System) on the clinical utility of reflex cytology by reducing screening error. DESIGN: A secondary analysis of a prospective cohort study. SETTING: One of five Dutch screening laboratories. POPULATION: Women tested hrHPV-positive on self-samples between December 2018 and August 2019. METHODS: Self-samples were used for reflex cytology with and without digital imaging. The follow-up data (cytological and histological results within 1 year of follow-up) were obtained through the Dutch Pathology Registry (PALGA). MAIN OUTCOME MEASURES: Test performance of the reflex cytology was determined by comparing it with physician-collected follow-up results. RESULTS: The sensitivity for detecting abnormal cells by reflex cytology on self-samples increased significantly from 26.3% (42/160; 95% confidence interval [CI] 19.6-33.8) without digital imaging to 35.4% (56/158; 95% CI 28-43.4) with digital imaging (P

Cervical adenocarcinoma (ADC) is the second most common pathological subtype of cervical cancer after squamous cell carcinoma. It accounts for approximately 20% of cervical cancers, and the incidence has increased in the past few decades, particularly among young patients. The persistent infection of high-risk human papillomavirus (HPV) is responsible for most cervical ADC. However, almost all available in vitro models are designed to study the carcinogenesis of cervical squamous cell carcinoma. To gain better insights into molecular background of ADC, we aimed to establish an in vitro carcinogenesis model of ADC. We previously reported the establishment of an in vitro model for cervical squamous cell carcinoma by introducing defined viral and cellular oncogenes, HPV16 E6 and E7, c-MYC, and activated RAS to human cervical keratinocytes. In this study, the expression of potential lineage-specifying factors and/or SMAD4 reduction was introduced in addition to the defined four oncogenes to direct carcinogenesis toward ADC. The cell properties associated with the cell lineage were analyzed in monolayer and organoid cultures and the tumors in mouse xenografts. In the cells expressing Forkhead box A2 (FOXA2), apparent changes in cell properties were observed, such as elevated expression of columnar cell markers and decreased expression of squamous cell markers. Strikingly, the histopathology of tumors expressing FOXA2 resembled cervical ADC, proposing that FOXA2 plays a vital role in dictating the histopathology of cervical cancers.

To evaluate the effectiveness and performance of Swedescore in the Swedish screening programme.Cross-sectional register study.All Swedish women aged over 18 years with a colposcopic assessment linked to a biopsy in the Swedish National Cervical Screening Registry, 2015-20.Colposcopies with Swedescore were compared with the histopathological diagnosis of cervical intraepithelial neoplasia grade 2 or higher (CIN2+). The respective influence of cytology and human papillomavirus (HPV) testing, at referral for colposcopy and concurrently with colposcopy, were investigated in regression models.CIN2+.A total of 11 317 colposcopic assessments with Swedescore were included. Odds ratios for CIN2+ increased for every step in the Swedescore scale. At Swedescore ≥0-1, the proportion of CIN2+ was 9.8%. At Swedescore ≥8, the specificity was 93.3% and the positive predictive value was 60.1%, Area under the receiver operating characteristics curve (AUC) was 0.71. If the smear had been abnormal at referral, a normal colposcopy (Swedescore 0-1) was still associated with a CIN2+ risk of more than 5%. In the regression model, cytology and HPV had higher odds ratio for CIN2+ than colposcopy; the combination resulted in an AUC of 0.88.Swedescore works well in a routine clinical setting but colposcopy assessed with Swedescore was inferior to that reported in previous clinical studies. No safe cutoff level was identified for refraining from biopsy. See-and-treat at Swedescore 8-10 is feasible only if referral cytology showed high-grade squamous intraepithelial lesion.No safe cutoff level for refraining from biopsy nor for see-and-treat with Swedescore.

Individuals are expected to be responsible for their own health and that of their families—and act accordingly. Yet, being in a position of responsibility might be undesirable for individuals either unable or reluctant to comply with the expectations this responsibility entails. In this article, I explore how parents experience the process of engaging responsibly with digital media in relation to the question of human papillomavirus vaccination. The study is based on interviews with eighteen Danish parents, and my findings show that these parents not only understand themselves but also other actors in terms of responsibility, and that being positioned in terms of responsibility can have negative affective consequences. I argue that meeting the expectations of biological citizenship should not necessarily be a goal in relation to complex health topics.

The World Health Organization recommends high-risk human papillomavirus (hrHPV)-based screening for women 39 to 49 years, based on the greater accuracy of hrHPV-based screening for cervical cancer detection. Many cervical cancer screening programs have incorporated hrHPV testing and multiple early cervical cancer detection strategies have been evaluated, mostly under controlled conditions. However, there are few evaluations of combined hrHPV and cytology strategies post-implementation at the population level. Our study sought to estimate the relative yield of hrHPV testing compared to cervical cytology, as a primary screening test for cervical intraepithelial neoplasia grade 2+ (CIN2+), used at the population level. We analyzed screening data from Mexico's public cervical cancer prevention program from 2010 to 2015 in women 35 to 64 years. The study population consisted of two cohorts: one from a total of 2 881 962 cytology-based screening tests and another from a total of 2 004 497 hrHPV-based screening tests, which are concurrent in time. We performed a relative yield analysis using Poisson regression models to compare the effectiveness of hrHPV testing for CIN2+ with cervical cytology. A total of 4 886 459 records were analyzed, including 23 999 biopsies; 0.12% (n = 6166) had a CIN2+ histologic diagnosis. hrHPV testing with cytological triage detects twice as many CIN2+ cases as screening using cytology alone.

The objective of this study was to analyze national trends in human papillomavirus (HPV) testing for patients diagnosed with sinonasal squamous cell carcinoma (SNSCC).Retrospective database study.National Cancer Database (2010-2016).Cases from 2010 to 2016 with a primary SNSCC diagnosis and known HPV testing status were extracted from the National Cancer Database. Univariate and multivariate analyses were then performed to assess differences in socioeconomic, hospital, and tumor characteristics between tested and nontested patients.A total of 2308 SNSCC cases were collected, with 1210 (52.4%) HPV tested and 1098 (47.6%) not tested. On univariate analyses, patient age, insurance, income quartile, population density, treatment facility location, and tumor grade were significantly associated with HPV testing status. After multivariate logistic regression modeling, living in a suburban area had lower odds of HPV testing as compared with living in urban areas (odds ratio, 0.74 [95% CI, 0.55-0.99];Among patients with SNSCC, those with high-grade tumors were more likely to be tested for HPV, while patients with a suburban area of residence were less likely. Additionally, there was no significant survival benefit to HPV testing, with tested and nontested groups having similar overall survival.4.

Introduction Previous studies have shown that individuals with human papillomavirus (HPV)‐related cervical lesions have different prognoses according to the HPV genotype. However, these studies failed to account for possible diagnostic misclassification. In this retrospective cohort study, we aimed to clarify the natural course of cervical lesions according to HPV genotype to account for any diagnostic misclassification. Materials and Methods Our cohort included 729 patients classified as having cervical intraepithelial neoplasia (CIN). HPV was genotyped in all patients, who were followed up or treated for cervical lesions at the University of Tokyo Hospital from October 1, 2008 to March 31, 2015. Hidden Markov models were applied to estimate the diagnostic misclassification probabilities of the current diagnostic practice (histology and cytology) and the transitions between true states. We then simulated two‐year transition probabilities between true cervical states according to HPV genotype. Results Compared with lesions in patients with other HPV genotypes, lesions in HPV 16‐positive patients were estimated to be more likely to increase in severity (i.e., CIN3/cancer); over 2 years, 17.7% (95% confidence interval [CI], 9.3%–29.3%) and 27.8% (95% CI, 16.6%–43.5%) of those with HPV 16 progressed to CIN3/cancer from the true states of CIN1 and CIN2, respectively, whereas 55%–70% of CIN1/2 patients infected with HPV 52/58 remained in the CIN1/2 category. Misclassification was estimated to occur at a rate of 3%–38% in the current diagnostic practice. Conclusion This study contributes robust evidence to current literature on cervical lesion prognosis according to HPV genotype and quantifies the diagnostic misclassification of true cervical lesions.

The prevalence of human papillomavirus (HPV) infection and HPV genotypes varies in different regions. However, there is little data on HPV prevalence and genotyping in Guangxi Province, South China. This study conducted a 10-year survey in a health center, to estimate the prevalence characteristics of HPV genotypes.By using polymerase chain reaction (PCR) amplification and nucleic acid molecular hybridization, the HPV genotypes were detected from 77,756 females who were patients of the Department of Obstetrics and Gynecology and those who visited the Health Management Center for a physical examination between August 2011 and November 2020. The prevalence, genotypes, age-related HPV infections, as well as chronological change of HPV prevalence, and the HPV genotype distribution were analyzed.The overall prevalence of HPV infection was 21.14% (16,439/77,756). The HPV infection rate differed significantly between the patients of the Department of Obstetrics and Gynecology and the women who underwent a physical examination (22.98% vs. 9.88%, p 0.05). The prevalence rates of high-risk HPV, low-risk HPV, mixed HPV (mixed high-risk, and low-risk HPV infection), and multiple HPV infections were 18.96% (14,739/77,756), 4.09% (3178/77,756), 1.90% (1478/77,756), and 4.94% (3838/77,756), respectively. The most prevalent genotypes were HPV 52, 16, and 58. The age-associated HPV prevalence showed bimodal curves, with the first peak at25 years and the second peak at56 years.This study provides baseline data on the HPV prevalence in the general female population of Nanning, Guangxi Province. Women25 and56 years old faced the greatest threat of HPV infection, and HPV 52, 16, and 58 were the most common genotypes.

This article examines human papillomavirus (HPV) self-sampling as an approach to cervical cancer prevention and the ways self-sampling kits are promoted directly to consumers in the United States. Public health, biomedicine and health tech have increasingly imagined self-sampling, which allows individuals to collect their own vaginal specimen, mail to a laboratory for testing and receive delivered results, as a component of cervical cancer prevention and sexual health promotion. This article examines the scientific and biomedical claims used to configure the problem in need of this solution and the ways persons, publics and markets are established. We analyse scientific literature, interviews with clinicians and other key actors, and websites of directly to consumers (DTC) companies. HPV self-sampling is constructed as both a solution to inequities and gaps in cervical cancer screening and a solution to the wants and needs of those already engaged in self-projects of body monitoring and risk reduction. These multidirectional biomedical tendencies also reveal how sexuality and sexual health and cervical cancer prevention and sexual health promotion are entangled objects. While we do not want to undermine the potential of HPV self-sampling, we encourage a focus on equity and care and not commodified markets that reinforce notions of 'good' patients monitoring their health.

Human papillomavirus (HPV) infection in men is a serious issue because it is associated with genital warts, anogenital cancers, and HPV transmission to their sex partners. This study aimed to investigate the prevalence and genotypes of HPVs in Vietnamese male patients hospitalized with sexually transmitted infection (STI) symptoms between 2016 and 2020 by using PCR and reverse dot blot hybridization analysis. HPV DNA was detected in 191/941 (20.3%) penile cell samples. The HPV patient's mean age was 30.3 in the range of 16- and 69-year-old. The highest HPV prevalence (84.7%) was found in patients between 20- and 39-year-old. A total of 313 HPV genotypes were identified. Multiple-infection rate was 42.9%. The most common high-risk (HR)-HPV genotypes were HPV-16 (8.0%), HPV-51 (7.7%), HPV-52 (4.8%), HPV-56 (4.2%), and HPV-18 (3.8%). Furthermore, HPV-11 and HPV-6 genotypes were the two most common low-risk (LR)-HPV genotypes with the rate of 36.7% and 21.4%, respectively. Notably, HPV-52 was found circulating in Vietnam for the first time. In conclusion, this study results showed that HPV prevalence in Vietnamese male patients was common and diverse. In addition, regarding public health and cancer prevention, the inclusion of the HPV vaccination into the national vaccination program for both men and women is recommended.

Gay, bisexual, and other men who have sex with men (MSM) and transgender women are disproportionately affected by human papillomavirus (HPV). HPV vaccination is routinely recommended for U.S. adolescents at age 11-12years, with catch-up vaccination through age 26years. We assessed HPV vaccination coverage and associated factors among young MSM and transgender women. The Vaccine Impact in Men study enrolled MSM aged 18-26years from clinics in Seattle, Chicago, and Los Angeles, during February 2016-September 2018. Participants self-reported socio-demographic information and HPV vaccination status. Among 1416 participants, 673 (47.5%) reported ≥1 HPV vaccine dose. Among vaccinated participants, median age at first dose was 19years and median age at first sex was 17years; 493 (73.3%) reported that their age at first dose was older than their age at first sex. There were significant differences in HPV vaccination coverage by city (range 33%-62%), age, race/ethnicity, and gender identity. Coverage was highest in Seattle, where younger age was the only factor associated with vaccination. Differences in coverage by city may be due to variation in vaccination practices or enrollment at study sites. Increasing both routine and catch-up vaccination will improve coverage among MSM and transgender women.

Introduction To direct interventions, the Florida counties with the greatest risk of current and future human papillomavirus‒associated cancers were identified by estimating county-level (1) percentages of adolescents aged 13–17 years who initiated (≥1 dose) and were up to date (2–3 doses) for the human papillomavirus vaccine and (2) human papillomavirus‒associated cancer incidence rates. Methods Records were obtained for human papillomavirus vaccinations from the Florida immunization registry (2006–2019), incident cancer cases from the Florida registry (2013–2017), and annual population counts from the Florida Department of Health (2006–2019). In 2020, annual county-level human papillomavirus vaccine initiation, human papillomavirus vaccine up-to-date, and age-adjusted human papillomavirus‒associated cancer incidence rates were estimated. Results Among adolescents aged 13–17 years, average 2018–2019 county-specific human papillomavirus vaccine initiation ranged from 38% to 100% for females and from 34% to 96% for males. Up-to-date estimates ranged from 20% to 72% for females and from 24% to 77% for males. The majority (78%) of counties with initiation and up-to-date estimates within the lowest tercile were located in Northern Florida. County-specific 2013–2017 annualized, adjusted human papillomavirus‒associated cancer incidence rates ranged from 0 to 29.8 per 100,000 among females and from 5.4 to 24.1 per 100,000 among males. Counties within the highest tercile for human papillomavirus‒associated cancers were primarily (90% for females and 77% for males) located in Northern Florida. Conclusions Human papillomavirus‒associated cancer risk varies widely across Florida counties, with particularly high risk within Northern Florida. Targeting interventions toward counties with low vaccination and high cancer rates may reduce human papillomavirus‒associated cancers.

The high-risk α-type papillomaviruses have a C-terminal PDZ-binding motif (PBM) on one of the two major oncoproteins E6 or E7; the vast majority on E6. The PBM is essential for the high-risk HPV life cycle, for episomal maintenance of the virus genome, and for maintaining the mitotic stability of the infected cell. The question is why only these viruses have PBMs - are there specific constraints imposed by the mucosal epithelium in which these viruses replicate? However the low-risk α-HPVs, such as HPV-6 and HPV-11 replicate extremely efficiently without a PBM, while viruses of the alpha8 group, such as HPV-40, replicate well with a very primitive PBM. So what does PDZ-binding capacity contribute to the fitness of the virus?

Most research models of HPV-associated squamous cervical carcinogenesis focus on stratified glycogenated squamous epithelium, a permissive environment for HPV-life-cycle completion, while immature squamous metaplastic epithelium and reserve cells as targets of HPV-infection have received less attention. Subcolumnar reserve cells of urogenital sinus origin with a CK17/p63-phenotype serve as the primary stem cell for squamous metaplasia. The area of manifest or potential squamous metaplasia, referred to as transformation zone, is the site where most squamous cancers occur after a transforming HPV infection of proliferating reserve cells and/or metaplastic epithelium. Improper use of terminology, in particular confusion of transformation zone with transition zone (synonymous: squamous-columnar junction or SCJ), as well as poorly substantiated postulates of a stem cell niche at the squamous-columnar junction with 'embryonic stem cell markers' have complicated understanding of HPV-related squamous carcinogenesis. Reserve cells as target cells and reservoirs of HPV should move into future research focus.

While platinum-based chemotherapy, radiation therapy and or surgery are effective in reducing human papillomavirus (HPV) driven cancer tumours, they have some significant drawbacks, including low specificity for tumour, toxicity, and severe adverse effects. Though current therapies for HPV-driven cancers are effective, severe late toxicity associated with current treatments contributes to the deterioration of patient quality of life. This warrants the need for novel therapies for HPV derived cancers. In this short review, we examined RNA-based therapies targeting the major HPV oncogenes, including short-interfering RNAs (siRNAs) and clustered regularly interspaced short palindromic repeats (CRISPR) as putative treatment modalities. We also explore other potential RNA-based targeting approaches such as microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and mRNA vaccines as future treatment modalities for HPV cancers. Some of these technologies have already been approved for clinical use for a range of other human diseases but not for HPV cancers. Here we explore the emerging evidence supporting the effectiveness of some of these gene-based therapies for HPV malignancies. In short, the evidence sheds promising light on the feasibility of translating these technologies into a clinically relevant treatment modality for HPV derived cancers and potentially other virally driven human cancers.

Aims To evaluate whether biomarkers derived from fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) performed prior to (prePET) and during the third week (interim PET; iPET) of radiotherapy can predict treatment outcomes in human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPC). Materials and methods This retrospective analysis included 46 patients with newly diagnosed OPC treated with definitive (chemo)radiation and all patients had confirmed positive HPV status (HPV+OPC) based on p16 immunohistochemistry. The maximum standardised uptake value (SUVmax), metabolic tumour volume (MTV) and total lesional glycolysis (TLG) of primary, index node (node with the highest TLG) and total lymph nodes and their median percentage (≥50%) reductions in iPET were analysed, and correlated with 5-year Kaplan–Meier and multivariable analyses (smoking, T4, N2b-3 and AJCC stage IV), including local failure-free survival, regional failure-free survival, locoregional failure-free survival (LRFFS), distant metastatic failure-free survival (DMFFS), disease-free survival (DFS) and overall survival. Results There was no association of outcomes with prePET parameters observed on multivariate analysis. A complete metabolic response of primary tumour was seen in 13 patients; the negative predictive value for local failure was 100%. More than a 50% reduction in total nodal MTV provided the best predictor of outcomes, including LRFFS (88% versus 47.1%, P = 0.006, hazard ratio = 0.153) and DFS (78.2% versus 41.2%, P = 0.01, hazard ratio = 0.234). More than a 50% reduction in index node TLG was inversely related to DMFFS: a better nodal response was associated with a higher incidence of distant metastatic failure (66.7% versus 100%, P = 0.009, hazard ratio = 3.0). Conclusion The reduction (≥50%) of volumetric nodal metabolic burden can potentially identify a subgroup of HPV+OPC patients at low risk of locoregional failure but inversely at higher risk of distant metastatic failure and may have a role in individualised adaptive radiotherapy and systemic therapy.

Human papillomavirus (HPV) infections cause more than 35,900 cancers annually in the United States. Although cervical cancer is the most prevalent HPV-related malignancy in women, the virus is also responsible for a significant percentage of anal, vaginal, and vulvar cancers. A comprehensive approach to mitigating cervical cancer includes HPV vaccination (primary prevention), screening and treatment of precancerous lesions (secondary prevention), and diagnosis and treatment of invasive cancer (tertiary prevention). Although a successful strategy, there are opportunities to innovate and increase access that can also be adapted to address the unique clinical care gaps that exist with the other anogenital cancers. The Society for Women's Health Research held a series of interdisciplinary meetings and events, during which expert researchers, clinicians, patient advocates, and health care policy leaders evaluated the current landscape of HPV-related cancers and their effects on women's health. This report summarizes the discussions of this working group and areas it identified in which to address gaps in primary and secondary prevention approaches to improve access and health outcomes for women with HPV-related anogenital cancers.

The Human Papilloma Virus (HPV) is one of the viruses that most affects the world's population. Its dissemination can lead to negative outcomes, including some types of cancer. However, when present during pregnancy, it seems to be linked to numerous pathological conditions ranging from premature birth to fetal death. Thus, it is imperative to investigate such an occurrence. Our aim was to assess the relationship between HPV infection and adverse outcomes in pregnancy and childbirth. For this, an integrative review on the subject was conducted in the PubMed, CINAHL and Scopus databases. Other findings were identified on the AskMEDLINE platform. After crossing the terms HPV, Pregnancy and Adverse Pregnancy Outcome, 115 studies were identified. Of these, only 10 fit the question proposed and the eligibility criteria outlined. When identified in pregnant women, the main adverse outcomes caused by HPV infection were premature rupture of membranes, premature birth, and spontaneous abortion. New studies need to expand investigations about the subtype of HPV and its complications in pregnancy. El Virus del Papiloma Humano (VPH) es uno de los virus que más afecta a la población mundial. Su diseminación puede conducir a resultados negativos, incluidos algunos tipos de cáncer. Sin embargo, cuando está presente durante el embarazo, parece estar relacionado con numerosas condiciones patológicas que van desde el nacimiento prematuro hasta la muerte fetal. Por lo tanto, es imperativo investigar tal ocurrencia. Nuestro objetivo fue evaluar la relación entre la infección por VPH y los resultados adversos en el embarazo y el parto. Para ello, se realizó una revisión integradora sobre el tema en las bases de datos PubMed, CINAHL y Scopus. Se identificaron otros hallazgos en la plataforma AskMEDLINE. Después de cruzar los términos HPV, Pregnancy y Adverse Pregnancy Outcome, se identificaron 115 estudios. De estos, solo 10 se ajustan a la pregunta propuesta y los criterios de elegibilidad descritos. Cuando se identificaron en mujeres embarazadas, los principales resultados adversos causados por la infección por VPH fueron: ruptura prematura de membranas, parto prematuro y aborto espontáneo. Nuevos estudios necesitan ampliar las investigaciones sobre el subtipo de VPH y sus complicaciones en el embarazo. O Papilomavírus Humano (HPV) é um dos vírus que mais acomete a população mundial. Sua disseminação pode carrear a desfechos negativos, dentre eles, alguns tipos de câncer. Todavia, quando presente na gravidez, parece estar ligado a inúmeros quadros patológicos que vão desde parto prematuro à óbito fetal. Assim, faz-se imperioso investigar tal ocorrência. O objetivo deste trabalho foi avaliar a relação entre a infecção pelo HPV e desfechos adversos na gravidez e no parto. Para isso, foi conduzida uma revisão integrativa sobre o tema, nas bases de dados PubMed, CINAHL e Scopus. Outros achados foram identificados na plataforma AskMEDLINE. Após o cruzamento dos termos HPV, Pregnancy e Adverse Pregnancy Outcome, foram identificados 115 estudos. Destes, apenas 10 se enquadraram na questão proposta e aos critérios de elegibilidade traçados. Quando identificado em gestantes, os principais desfechos adversos causados pela infecção do HPV foram: ruptura prematura de membranas, parto prematuro e aborto espontâneo. Novos estudos precisam ampliar as investigações acerca do subtipo do HPV e suas complicações na gravidez.

Purpose: We aim to carry out an investigation on the impact of cervical oncogenic human papillomavirus (HPV) infection in pregnant adolescents, to clarify the prevalence and risk factors, considering the importance and lack of data on this topic in Brazil.Methods: A cross-sectional study was conducted with adolescents receiving specialized prenatal care in a tertiary hospital in São Paulo, Brazil. On the first prenatal visit, were performed an oncotic colpocytological exam and an oncogenic-HPV assessment of the uterine cervix. We sought the association these exams with demographic and obstetric variables.Results: A total of 303 pregnant adolescents whose mean age was 15.30 ± 1.22 years comprised the study subjects. The prevalence of high-risk HPV cervical infection was 50.50%. Multivariate analysis revealed that a large number of partners in their lifetime (OR=1.268) and having a religion (OR=2.054) were risk factors for oncogenic HPV-caused cervical infection, while schooling appeared as a protective factor (OR=0.847). There was an association between Oncogenic HPV infection and colpocytological alterations, reaching almost 30% of patients. There was no association between Oncogenic HPV infection and obstetric outcomesConclusion: The prevalence found is one of the highest in Brazil and worldwide. A greater number of partners during their lifetime and having religion were detected as possible factors associated with cervical HPV infection. The findings of this study reinforce the need to implement measures of health education and prevention capable of modifying the incidence of cytopathological cervical lesions and of uterine cervix cancer in this population.

The role of human papillomavirus (HPV) in keratoacanthoma (KA) remains unclear.To identify possible differences in HPV DNA, detected by next-generation sequencing (NGS), between KAs and cutaneous squamous cell carcinomas (cSCCs), which may suggest different pathogenesis.We extracted DNA from formalin-fixed and paraffin-embedded (FFPE) tissue blocks from samples of 151 patients (105 with cSCCs and 46 with KAs). HPV DNA was detected using the NGS-based Ezplex® kit. HPV detection rates and other clinical characteristics were compared.HPV was detected in 6.7% (7/105) of cSCC and 10.9% (5/46) of KA samples. Eight alpha-HPV genotypes (16, 57, 81, 31, 33, 45, 53, and 58) were detected, with HPV 16 being the most common. Only one type (57) is commonly classified as cutaneous type, and the rest are all mucosal types. HPV detection rate did not significantly differ between the KA and cSCC groups.HPV detection was relatively low in KA and cSCC samples. HPV might be related to the pathogenesis of only selected KA and cSCC cases.
