RESUMEN

Oropharyngeal human papillomavirus (HPV) cancers are prevalent, but HPV education in dental clinics is uncommon. The purpose of this study was to evaluate dental provider and patient knowledge from, attitudes towards, and preferences for HPV education, then assess perceptions of existing HPV educational materials for use at dental visits. Appalachian Ohio dental patients (n = 13) and general/pediatric dental providers (n = 10) completed an initial, close-ended survey on current HPV knowledge and HPV educational attitudes, participation, and resource preferences. Select individuals reviewed existing HPV educational videos and toolkits via virtual focus groups (n = 9) or independent review surveys (n = 6). Using a discussion guide, participants responded to overall, visual, auditory, and content satisfaction statements, orally (focus groups) or with Likert scales (independent reviews). Surveys were summarized with frequencies/percentages; transcripts were qualitatively coded to identify potential material modifications. Dental providers and patients were more comfortable with HPV and oral cancer education (87% and 96%, respectively) and screening (96%) than with HPV vaccine education (74%) and referrals (61%) during dental visits. Providers were neither sharing HPV educational materials (80%) nor initiating educational conversations with dental patients (100%). The American Cancer Society videos and the "Team Maureen" toolkit were the most liked resources (i.e., fewer negative/disagree statements) by all participant groups. Findings indicate that future dental HPV educational efforts should be informed by currently available materials. Additional interventions are needed to promote dental provider discussions and sharing of educational materials with patients to increase education and promotion of the HPV vaccine and reduce oropharyngeal cancers.

RESUMEN

Mexico's national human papillomavirus (HPV) vaccination program was established in 2008, providing free access to HPV vaccines and quickly becoming an immense success story, achieving significant coverage among young Mexican females. However, despite these efforts and notable achievements, cervical cancer caused mainly by HPV remains a challenging issue among Mexican women aged 15 years or older. A critical obstacle faced by women in the country is a lack of early detection and screening resources, coupled with delays in diagnosis and treatment, exacerbated by the poor distribution of already insufficient healthcare resources. This situation creates adverse conditions for the female demographic in the country. Our editorial aims to draw attention to the urgent need to improve access to adequate prevention, screening, and treatment for cervical cancer patients in Mexico, advocating for a collective effort between the Mexican government, public health professionals, and civil society.

RESUMEN

BACKGROUND: High-risk human papillomavirus (HR-HPV) infection is an important factor for the development of cervical cancer. HPV18 is the second most common HR-HPV after HPV16. METHODS: In this study, MEGA11 software was used to analyze the variation and phylogenetic tree of HPV18 E6-E7 and L1 genes. The selective pressure to E6, E7 and L1 genes was estimated using pamlX. In addition, the B cell epitopes of L1 amino acid sequences and T cell epitopes of E6-E7 amino acid sequences in HPV18 were predicted by ABCpred server and IEDB website, respectively. RESULTS: A total of 9 single nucleotide variants were found in E6-E7 sequences, of which 2 were nonsynonymous variants and 7 were synonymous variants. Twenty single nucleotide variants were identified in L1 sequence, including 11 nonsynonymous variants and 9 synonymous variants. Phylogenetic analysis showed that E6-E7 and L1 sequences were all distributed in A lineage. In HPV18 E6, E7 and L1 sequences, no positively selected site was found. The nonconservative substitution R545C in L1 affected hypothetical B cell epitope. Two nonconservative substitutions, S82A in E6, and R53Q in E7, impacted multiple hypothetical T cell epitopes. CONCLUSION: The sequence variation data of HPV18 may lay a foundation for the virus diagnosis, further study of cervical cancer and vaccine design in central China.

RESUMEN

The most common type of melanoma is cutaneous melanoma (CM). The predominant mutational signature is that of ultraviolet radiation (UVR) exposure. The Cancer Genome Atlas (TCGA) molecular classification includes four major subtypes of CM based on common genetic alterations involving the following genes: BRAF, NRAS, and NF1, with a small fraction being "triple" wild-type. The two main signaling pathway abnormalities in CM are the mitogen-activated protein kinase (MAPK) pathway and the phosphoinositol-3-kinase (PI3K) pathway. Other less common types include mucosal melanomas (MM) and uveal melanoma (UM), which have a significantly different genomic landscape. Although few studies reported rare cases with HPV-positive (HPV+) melanoma, the clinicopathological and molecular characteristic of this entity has not been well-described. Among the 2084 melanoma cases queried at our institution, we identified seven patients diagnosed with HPV+ melanoma (prevalence 0.03 %), including five instances of CM and two of MM. The majority of cases were positive for HPV16 (n = 6). Most of the patients were elderly and with advanced disease (n = 6), although this finding may be attributed to the relative frequency of our institution testing advanced-stage tumors. Histologically, most cases showed high degree of pleomorphism and high mitotic count (5 or more mitoses/mm2) (n = 6). UVR signature was present in the CM, but not in the MM cases. Alterations in either MAPK and/or PI3K pathways were detected in the majority of cases (n = 6). The most common genetic abnormalities detected in this study occurred in the TERT promoter (TERTp) (n = 5), a finding that has been reported to be associated with aggressive disease. Our data shows that while HPV+ melanoma is rare, identifying this disease entity could help guide therapy given the demonstrated genomic alterations.

RESUMEN

Cervical cancer affects women worldwide and is the most common human papillomavirus (HPV)-associated cancer. Carcinogenesis caused by HPV results in specific cancer behavior because of the underlying viral infection. The mechanism and timing of the transformation from viral infection to cancer cells have been elucidated in detail. Treatments for this cancer are based on its characteristics and are being implemented. Moreover, HPV infection is widespread worldwide and is transmitted through sexual activity. Although the HPV vaccination is the most effective strategy of preventing cervical cancer, it is not feasible to vaccinate the entire human population especially in low- and middle-income countries. In order to consider the next step for HPV vaccination, we need to understand the characteristics of HPV carcinogenesis and cervical cancer. Additionally, treatment aimed at preservation of reproductive function in patients with cervical cancer is often required, as the cervix is a reproductive organ and because the disease is more prevalent in the adolescent and young adult generation. Thus, there are still many challenges in the diagnosis, treatment, and prevention of cervical cancer.

RESUMEN

Human papillomavirus (HPV) has been implicated in various cancers, including those affecting the skin. The study assessed the long-term risk of skin cancer associated with HPV infection in Taiwan region, using data from the National Health Insurance Research Database between 2007 and 2015. Our analysis revealed a significant increase in skin cancer risk among those with HPV, particularly for squamous cell carcinoma (SCC), the subtype with the highest observed adjusted hazard ratio (aHR) = 5.97, 95% CI: 4.96-7.19). The overall aHR for HPV-related skin cancer was 5.22 (95% CI: 4.70-5.80), indicating a notably higher risk in the HPV-positive group. The risk of skin cancer was further stratified by type, with basal cell carcinoma (aHR = 4.88, 95% CI: 4.14-5.74), and melanoma (aHR = 4.36, 95% CI: 2.76-6.89) also showing significant associations with HPV. The study also highlighted regional variations, with increased risks in southern Taiwan and the Kaohsiung-Pingtung area. Key findings emphasize the importance of sun protection, particularly in regions of high UV exposure and among individuals in high-risk occupations. This research contributes to a better understanding of the complex interactions between HPV and skin cancer risk, reinforcing the importance of preventive strategies in public health.

RESUMEN

Men aged 27 to 45 are eligible for human papillomavirus (HPV) vaccination as of 2019, yet relatively little is known about whether they have received or intend to receive it. We conducted a cross-sectional, online survey among fathers aged 27 to 45 between March and April 2022, to assess associations between HPV vaccination awareness, behaviors, intentions, and psychosocial constructs from the Health Belief Model. We examined the characteristics of those who had (a) heard of the HPV vaccine, (b) already received ≥ 1 dose, and (c) intentions for future vaccination among those who had never been vaccinated. Among 400 men who completed the survey, 32% were not aware of the HPV vaccine. Among those who were aware, 41% had received ≥ 1 dose. Sixty-three percent of unvaccinated men reported that they intended to get vaccinated in the future. Multivariable logistic regression analyses revealed that age and race/ethnicity were associated with having been vaccinated previously. Among the unvaccinated, multivariable logistic regression analyses revealed that those with a higher perceived risk of HPV-associated cancer had 3.73 greater odds of reporting they would seek vaccination compared to those with lower perceived risk (95% confidence interval [CI] = [1.28, 12.3]). We did not find perceived benefits, barriers, or decision self-efficacy to be related to future vaccine intentions. Since recommendations for this group include shared clinical decision-making, public health efforts should focus on raising awareness of vaccine eligibility, emphasizing risk factors for HPV-associated cancers so that individuals have an accurate perception of risk, and encouraging conversation between men and their providers.

RESUMEN

BACKGROUND: Primary cervical cancer screening and treating precancerous lesions are effective ways to prevent cervical cancer. However, the coverage rates of human papillomavirus (HPV) vaccines and routine screening are low in most developing countries and even some developed countries. This study aimed to explore the benefit of an artificial intelligence-assisted cytology (AI) system in a screening program for a cervical cancer high-risk population in China. METHODS: A total of 1231 liquid-based cytology (LBC) slides from women who underwent colposcopy at the Chinese PLA General Hospital from 2018 to 2020 were collected. All women had received a histological diagnosis based on the results of colposcopy and biopsy. The sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV), false-positive rate (FPR), false-negative rate (FNR), overall accuracy (OA), positive likelihood ratio (PLR), negative likelihood ratio (NLR) and Youden index (YI) of the AI, LBC, HPV, LBC + HPV, AI + LBC, AI + HPV and HPV Seq LBC screening strategies at low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion (HSIL) thresholds were calculated to assess their effectiveness. Receiver operating characteristic (ROC) curve analysis was conducted to assess the diagnostic values of the different screening strategies. RESULTS: The Se and Sp of the primary AI-alone strategy at the LSIL and HSIL thresholds were superior to those of the LBC + HPV cotesting strategy. Among the screening strategies, the YIs of the AI strategy at the LSIL + threshold and HSIL + threshold were the highest. At the HSIL + threshold, the AI strategy achieved the best result, with an AUC value of 0.621 (95% CI, 0.587-0.654), whereas HPV testing achieved the worst result, with an AUC value of 0.521 (95% CI, 0.484-0.559). Similarly, at the LSIL + threshold, the LBC-based strategy achieved the best result, with an AUC of 0.637 (95% CI, 0.606-0.668), whereas HPV testing achieved the worst result, with an AUC of 0.524 (95% CI, 0.491-0.557). Moreover, the AUCs of the AI and LBC strategies at this threshold were similar (0.631 and 0.637, respectively). CONCLUSIONS: These results confirmed that AI-only screening was the most authoritative method for diagnosing HSILs and LSILs, improving the accuracy of colposcopy diagnosis, and was more beneficial for patients than traditional LBC + HPV cotesting.

RESUMEN

The evolutionary journey of cervical cancer screening has been a major medical success story, considering the substantial role it has played in dwindling the disease burden. Through sustained collaborative efforts within the medical community, significant advances have been made from the humble yet path-breaking conventional Pap smear to the current automated screening systems and human papillomavirus (HPV) molecular testing. With the integration of artificial intelligence into screening techniques, we are currently at the precipice of circumventing the pitfalls of manual cytology readings and improving the efficiency of the screening systems by a significant margin. Despite the technological milestones traversed, the high logistics and operational cost, besides the technical know-how of operating the automated systems, can pose a major practical challenge in the widespread adoption of these advanced techniques in cervical cancer screening programs. This would suggest the need to adopt strategies that are tailored to the demands and needs of the different settings keeping their limitations in mind. This review aims to take the reader through the entire evolutionary journey of cervical cancer screening programs, highlight the individual merits and demerits of each technique, and discuss the recommendations from the major global guidelines.

RESUMEN

BACKGROUND: A cytologic diagnosis of atypical squamous cells, cannot exclude high-grade squamous lesion (ASC-H) poses a disproportionately high risk of cervical cancer development. The objective of this study was to analyze type-specific risks by mapping human papillomavirus (HPV) genotypes in ASC-H cytology. METHODS: In total, 1,048,581 Papanicolaou tests that had ASC-H cytology were retrieved. Concurrent HPV genotyping using proprietary multiplex real-time (MRT) and polymerase chain reaction (PCR) HPV tests and histologic follow-up findings were analyzed. RESULTS: Among 1678 patients who had ASC-H findings (0.16%), 1414 (84.3%) underwent concurrent HPV genotyping (MRT, 857; HPV PCR test, 557). The overall high-risk HPV (hrHPV)-positive rate was 84.4%. Of the 857 MRT cases, 63.9% were infected with a single hrHPV, and 24.4% had multiple genotypes. The most prevalent HPV types were HPV16/52/58/33/31. Lesions that were identified as cervical intraepithelial neoplasia 2 or worse (CIN2+) were detected in 498 of 906 cases (55.0%), including 81 cervical carcinomas (8.9%). The risk of CIN2+ for the composite group of HPV16/52/58/33/31-positive cases was 62.7%, representing 90.7% (264 of 291) of total CIN2+ lesions in ASC-H/hrHPV-positive cases by MRT. CIN2+ lesions were detected in 108 of 142 (76.1%) HPV16-positive and/or HPV18-positive women by the PCR the HPV test. Among 128 hrHPV-negative ASC-H cases by both methods, CIN2+ lesions were identified in 21 of 128 (16.4%), including five cervical carcinomas (3.9%). The sensitivity, specificity, positive predictive value, and negative predictive value for patients in the composite group with HPV16/52/58/33/31 were 88.0%, 40.8%, 62.7%, and 75.0%, respectively. CONCLUSIONS: Papanicolaou tests classified as ASC-H are associated with a high CIN2+ rate and warrant colposcopy, regardless of HPV status. The extent to which the risk-stratification provided by comprehensive HPV genotyping can inform the management of ASC-H cytology remains to be explored.

RESUMEN

BACKGROUND: France has the sixth highest incidence of oropharyngeal cancer (OPC) in Europe, but the epidemiological impact of high-risk HPV (HR-HPV) remains poorly documented. The objective of our study was to assess the proportion of OPCs caused by HR-HPV in Paris, and its suburbs, over the four past decades. This area accounts for almost one-fifth of the total population of France. METHODS: OPCs diagnosed in 1981, 1986, 1991, 1996, 2001, 2006, 2011, 2016 and 2020/2021 in two of the main referral cancer centers for HNCs in Paris and its suburbs were retrieved from the tumor biobanks. HPV status was determined by p16-staining and HPV-DNA detection. Samples were considered HPV-driven if both assays were positive. Results were compared to the French cancer registry data. RESULTS: Samples from 697 OPC patients were assessed (including 82 % of all samples diagnosed in 2001, 2006, 2011, 2016, 2021). The proportion of HPV-driven cases rose from 2.7 % to 53 % between 1981 and 2021. HPV16 was the dominant genotype during the study period. Of patients with HPV-driven OPC, 81 % were male and 42 % were smokers versus 80 % and 92 % in their HPV-negative counterparts. The age of OPC patients increased significantly, during the study period, independent of their HPV status CONCLUSION: The proportion of HPV-driven OPCs has significantly increased in Paris and its suburbs, during the last four decades. OPCs has become the 2nd predominant type of head and neck cancer, in France. This may be linked to the rise in HPV-driven cases and the decrease of tobacco and alcohol consumption in men.

RESUMEN

Human papillomaviruses (HPVs) are double-stranded DNA (dsDNA) tumor viruses causally associated with 5% of human cancers, comprising both anogenital and upper aerodigestive tract carcinomas. Despite the availability of prophylactic vaccines, HPVs continue to pose a significant global health challenge, primarily due to inadequate vaccine access and coverage. These viruses can establish persistent infections by evading both the intrinsic defenses of infected tissues and the extrinsic defenses provided by professional innate immune cells. Crucial for their evasion strategies is their unique intraepithelial life cycle, which effectively shields them from host detection. Thus, strategies aimed at reactivating the innate immune response within infected or transformed epithelial cells, particularly through the production of type I interferons (IFNs) and lymphocyte-recruiting chemokines, are considered viable solutions to counteract the adverse effects of persistent infections by these oncogenic viruses. This review focuses on the complex interplay between the high-risk HPV oncoproteins E6 and E7 and the innate immune response in epithelial cells and HPV-associated cancers. In particular, it details the molecular mechanisms by which E6 and E7 modulate the innate immune response, highlighting significant progress in our comprehension of these processes. It also examines forward-looking strategies that exploit the innate immune system to ameliorate existing anticancer therapies, thereby providing crucial insights into future therapeutic developments.

RESUMEN

Cervical cancer, caused due to oncogenic types of human papillomavirus (HPV), is a leading preventable cause of cancer morbidity and mortality globally. Chronic, persistent HPV infection-induced cervical precursor lesions, if left undetected and untreated, can progress to invasive cancer. Cervical cancer screening approaches have evolved from cytology (Papanicolaou test) to highly sensitive HPV-based molecular methods and personalized, risk-stratified, management guidelines. Innovations like self-collection of samples to increase screening access, innovative triage methods to optimize management of screen positives, and scalable and efficacious precancer treatment approaches will be key to further enhance the utility of prevention interventions.

RESUMEN

BACKGROUND: Human Papillomavirus (HPV), a prevalent sexually transmitted infection carrying significant risks ranging from benign lesions to various types of malignancies, represents a matter of great public health concern. Notably, most Arab countries lack public awareness campaigns or national immunization programs. This study aims at assessing the overall knowledge on HPV and HPV vaccination among the Lebanese population, exploring the prevalent attitude on the matter, and identifying barriers and misconceptions that prevent individuals from receiving the HPV vaccine. METHODS: A cross-sectional study was conducted in Beirut, on 201 participants aged between 18 and 36 years old. We performed ordinal analysis to assess the trend between Knowledge levels, attitude levels and hesitancy Levels. RESULTS: Majority of participants (77%) demonstrated a low level of knowledge on HPV vaccination, 50% held a positive attitude, with only 18.4% being already vaccinated. Negative trend was identified between levels of knowledge, attitude and hesitancy (gamma = -0.7415, p-value < 0.01; gamma= -0.58, p-value < 0.01 respectively). Unavailability or limited access to the vaccine, and misconceptions about HPV immunization were shown to be impeding vaccination. CONCLUSION: Analysis of our results strongly suggests that improving knowledge and attitudes is likely to foster trust and reduce hesitancy, thereby promoting higher vaccine uptake.

RESUMEN

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

RESUMEN

BACKGROUND: Human papillomavirus (HPV) infection is a major worldwide public health concern that can result in a range of clinical disorders, including cervical cancer. Saudi Arabia, similar to numerous other nations, has difficulties in facing HPV and its impact on society. The high incidence of cervical cancer in Saudi Arabia continues to be a cause for worry, highlighting the need for the adoption of efficient immunization programs. Nevertheless, public hesitation and inadequate knowledge can hinder the acceptance of vaccines. Evaluating public knowledge and attitudes concerning HPV and its vaccination is essential in order to create focused programs that enhance awareness and increase vaccine acceptance. METHODS: This study was cross-sectional in nature, using data from a sample of 516 Saudi participants 18 years and above. The participants completed online questionnaires that were distributed using Google Forms across social media platforms and ensured anonymity. RESULTS: A total of 516 participants made up the sample for this study, which had a predominance of females (83.5%, n=431); the majority aged 18-25 years (78.3%, n=404) and most of them (28.3%, n=146) were from the central region. The study results revealed that 43.7% (n=225) of the participants had a good knowledge level while 56.3% (n=291) of them had a poor level of knowledge about the HPV vaccine. A substantial proportion (35.9%, n=185) of the participants had good knowledge that HPV can be transmitted sexually from one person to another with only 30.2% (n=156) of them being aware that HPV is a common infection that causes cervical cancer (41.5%, n=214) and most of them (76.2%, n=393) knew that cervical cancer can be cured particularly when detected in early stages. The results established statistically significant associations between gender, education level, and occupation with p-values <0.005 (0.023, 0.003 and 0.001 respectively) and level of knowledge about the HPV vaccine. CONCLUSION: The study emphasizes the necessity of implementing focused health education and vaccination initiatives in Saudi Arabia to enhance understanding and attitudes regarding HPV infection and its vaccine. The results can provide guidance to healthcare professionals, legislators, and public health authorities in creating programs that increase knowledge and acceptance of the HPV vaccine, ultimately decreasing the prevalence of HPV-related diseases in the nation.

RESUMEN

Human papillomavirus (HPV) is a common sexually transmitted infection. Despite a safe and effective vaccine, uptake continues to be suboptimal. Recently, focus has moved to college campuses in an effort to increase vaccination rates. Little is known about the extent of efforts to reach graduate students on college campuses in the United States and the vaccination rates within this subpopulation. This scoping review assessed the literature on knowledge, attitudes, beliefs, and behaviors about HPV and HPV vaccination among graduate and post-baccalaureate professional students in the United States. This review also aims to identify areas for further research to improve institutions' abilities to create health programming to increase HPV awareness and HPV vaccination coverage on their campuses. Publications focusing on knowledge, attitudes, beliefs, and behaviors about HPV and HPV vaccination in post-baccalaureate students were included. The systematic review of PubMed, CINAHL, and Embase identified 2562 articles, and 56 articles met all inclusion criteria and were included in this scoping review. A majority of the reviewed studies investigated some combination of knowledge, attitudes, behaviors, and beliefs about HPV and the HPV vaccine in students in professional programs such as medicine.
