The oral squamous cell carcinoma (OSCC) 5 year survival rate of 41% has marginally improved in the last few years, with less than a 1% improvement per year from 2005 to 2017, with higher survival rates when detected at early stages. Based on histopathological grading of oral dysplasia, it is estimated that severe dysplasia has a malignant transformation rate of 7%–50%. Despite these numbers, oral dysplasia grading does not reliably predict its clinical behavior. Thus, more accurate markers predicting oral dysplasia progression to cancer would enable better targeting of these lesions for closer follow‐up, especially in the early stages of the disease. In this context, molecular biomarkers derived from genetics, proteins, and metabolites play key roles in clinical oncology. These molecular signatures can help predict the likelihood of OSCC development and/or progression and have the potential to detect the disease at an early stage and, support treatment decision‐making and predict treatment responsiveness. Also, identifying reliable biomarkers for OSCC detection that can be obtained non‐invasively would enhance management of OSCC. This review will discuss biomarkers for OSCC that have emerged from different biological areas, including genomics, transcriptomics, proteomics, metabolomics, immunomics, and microbiomics.

Human Papilloma virus (HPV) role has now been widely accepted as a causative agent for cervical as well as head and neck squamous cell carcinomas. Screening and early detection of cervical cancer remains the key element to eradicate this deadly disease. Since it has a long natural history and disease progression, this gave an opportunity for early detection through screening of precancerous lesions which was adopted in high income countries (HIC) like UK which has led to the significant reduction of the cases. Unfortunately, Low- and middle-income countries are facing huge burden because of the lack of effective screening program. FDA approved Cervarix, Gardasil and Gardasil 9 are used as prophylaxis for cervical cancer & genital warts but screening is still essential after vaccination because these vaccines are not effective against all types of HPV types. HPV 16 & HPV 18 are highly oncogenic types and accounts for 70% of cervical cancers. The use of vaccine reduces the risk of getting HPV infection and decrease the rate of morbidity and mortality due to the cervical cancer. In addition to vaccines, many peptides or protein-based & cell or DNA-based vaccines are still in clinical trials; these prevention and management available in vaccines are likely to come up with significant benefits of health in future. Although it's usually cured by immune system but presence of certain cofactors such as smoking, HIV etc. reduces the probability of an individual to eradicate the infection effectively. The aim of this study is to review literature regarding HPV related infections and malignancies. Moreover, it will make individuals aware about prophylaxis & treatment options available for HPV infection. This review article evaluates the HPV related diseases, there screening, evaluation and management currently available. [ABSTRACT FROM AUTHOR]

One subgroup of Latinos whose healthcare needs must be more thoroughly addressed is the roughly three million farmworkers pursuing seasonal agricultural work within the United States (U.S.). Latino migrant and seasonal farmworkers (MSFW) face compounded political, social, and personal contexts that complicate healthcare access. Although the human papillomavirus (HPV) vaccine prevents HPV infections and cancers, uptake among Hispanic adolescents remains suboptimal. Therefore, it is important to understand Latino MSFW's HPV knowledge, as well as barriers to and facilitators of vaccination so culturally appropriate measures can bolster vaccination. An integrative review was conducted in PubMed, Scopus, and Web of Science using key search terms. Results were evaluated for compatibility with inclusion/exclusion criteria, and selected articles were coded and evaluated via thematic analysis. Six studies of various designs were ultimately included in the review. While some Latino MSFW have baseline knowledge about HPV and the vaccine, knowledge gaps remain. Participants expressed curiosity about how the vaccine works, contents, side effects, dosing, recommended age, and information about prevented diseases. Although additional education and MSFW's receptiveness to provider's recommendations were cited as major facilitators, many barriers also need addressed. Providers must leverage MSFW's existing knowledge, provide education, and facilitate vaccination to protect farmworker families from HPV and related cancers. It must become standard practice for providers to recommend the HPV vaccine to MSFW, who are receptive to this conversation. Increasing vaccination can decrease the disproportionate burden of HPV-related cancers on patients and facilitate access to healthcare services. [ABSTRACT FROM AUTHOR]

Background: For women, cervical cancer is the most prevalent cancer and the most common cause of cancer-related deaths worldwide. Human papillomavirus (HPV) is causatively linked to over 90% of cervical cancer cases. Our retrospective study explored the clinical and laboratory data of outpatients with HPV infection to analyze the prevalence and genotype distribution of 3,793 outpatients in the Hangzhou area by using HPV genotype tests. It could provide value for an effective prevention and treatment of HPV infection. Methods: In total, 3,793 female outpatients were randomly selected from January 2022 to December 2023. Exfoliated cervical cells were collected using a cytobrush and HPV genotype screening was conducted for testing. Data of all outpatients were collected from the hospital's electronic medical records, and SPSS 26.0 software was used to perform the statistical analysis. Results: Out of 3,793 outpatients, 953 were detected as positive, and the positive rate was 25.13%. The age of the outpatients ranged from 15 - 97, with an average age of 39.91. All outpatients were divided into six age groups. Among the six age groups, the HPV positive rates were, with ascending age, 43.90%, 33.27%, 21.49%, 16.99%, 27.30%, and 25.48%, and the highest positive rate was observed in those aged ≤ 20 with a rate of 43.90%. There were significant differences in the positive rates among different age groups (p < 0.05). There were more outpatients with a single infection than with multiple infection (p < 0.05). The positive rate of single infection was the highest in the 31 - 40 and 41 - 50 age groups (74.32% for both) and the positive rate of multiple infection was the highest in the ≤ 20 age group (66.67%). Among 24 genotypes, HPV 52, 58, and 51 were the most commonly detected. All three were high-risk genotypes, and HPV 52 was the most dominant in all age groups. As distribution according to quarter, more HPV infection occurred in the fourth quarter, which had a significant difference (p < 0.05). And in the first quarter, the number of HPV positive infections was the lowest. Conclusions: Prevalence and genotype distribution of HPV in the Hangzhou area were different from those of other regions. More single infection, and more multiple infection occurring in low age and in the fourth quarter were the characteristics of HPV infection in the Hangzhou area. It was suggested that vaccine containing HPV 52 might be a better choice for this region. [ABSTRACT FROM AUTHOR]

BackgroundThe incidence of oropharyngeal cancer (OPC) is increasing, due mainly to a rise in Human Papilloma Virus (HPV)-mediated disease. HPV-mediated OPC has significantly better prognosis compared with HPV-negative OPC, stimulating interest in treatment de-intensification approaches to reduce long-term sequelae. Routine clinical testing frequently utilises immunohistochemistry to detect upregulation of p16 as a surrogate marker of HPV-mediation. However, this does not detect discordant p16-/HPV+ cases and incorrectly assigns p16+/HPV- cases, which, given their inferior prognosis compared to p16+/HPV+, may have important clinical implications. The biology underlying poorer prognosis of p16/HPV discordant OPC requires exploration.MethodsGeoMx digital spatial profiling was used to compare the expression patterns of selected immuno-oncology-related genes/gene families (n=73) within the tumour and stromal compartments of formalin-fixed, paraffin-embedded OPC tumour tissues (n=12) representing the three subgroups, p16+/HPV+, p16+/HPV- and p16-/HPV-.ResultsKeratin (multi KRT) and HIF1A, a key regulator of hypoxia adaptation, were upregulated in both p16+/HPV- and p16-/HPV- tumours relative to p16+/HPV+. Several genes associated with tumour cell proliferation and survival (CCND1, AKT1 and CD44) were more highly expressed in p16-/HPV- tumours relative to p16+/HPV+. Conversely, multiple genes with potential roles in anti-tumour immune responses (immune cell recruitment/trafficking, antigen processing and presentation), such as CXCL9, CXCL10, ITGB2, PSMB10, CD74, HLA-DRB and B2M, were more highly expressed in the tumour and stromal compartments of p16+/HPV+ OPC versus p16-/HPV- and p16+/HPV-. CXCL9 was the only gene showing significant differential expression between p16+/HPV- and p16-/HPV- tumours being upregulated within the stromal compartment of the former.ConclusionsIn terms of immune-oncology-related gene expression, discordant p16+/HPV- OPCs are much more closely aligned with p16-/HPV-OPCs and quite distinct from p16+/HPV+ tumours. This is consistent with previously described prognostic patterns (p16+/HPV+ >> p16+/HPV- > p16-/HPV-) and underlines the need for dual p16 and HPV testing to guide clinical decision making.

Abstract Introduction Cervical cancer is a major public health issue in Uganda, with high incidence due to limited screening especially in rural areas. In 2019, HPV DNA testing using GeneXpert was rolled out to improve screening access. Assessing progress and challenges since its introduction is important. Aim To determine genotype distribution and explore health worker experiences with HPV screening using GeneXpert in Uganda. Methods We conducted a retrospective cohort study where HPV screening data from 66 GeneXpert labs from March 2021-May 2023 country wide was analyzed. We used descriptive statistics to provide percentages and proportions from the data. Seven focus group discussions and five interviews were done with health workers to understand experiences. Results We extracted 24,497 HPV tests that were done, and 39.1% were HPV positive. Other high-risk HPV genotypes were the most common at 65%, followed by HPV 16 (17%) and HPV 18/45 (18%). 15% of the HPV positive cases had more than one genotype. Qualitative findings showed inconsistent health worker knowledge, high workload, and complex care seeking behaviors as main challenges. It also revealed low community awareness, care seeking from traditional healers, Conclusion HPV DNA testing has been expanding since its rollout, but the yield of HPV cases is lower than expected, signaling need to address supply-side challenges. Limited information on HPV among health workers especially community health workers, demand-side barriers like myths, medical pluralism and social norms must also be tackled through trainings of health workers and awareness campaigns engaging communities. Although access to GeneXpert services has increased, health system weaknesses pose bottlenecks to screening HPV. Targeted interventions are required to strengthen HPV diagnosis, prevent cervical cancer and save lives.

Background: Aberrant DNA methylation is a common epigenetic modification in cancers, including oropharyngeal squamous cell carcinoma (OPSCC) and oral squamous cell carcinoma (OSCC). Therefore, the analysis of methylation levels appears necessary to improve cancer therapy and prognosis. Methods: The enzyme-linked immunosorbent assay (ELISA) was used to analyse global DNA methylation levels in OPSCC and OSCC tumours and the margin samples after DNA isolation. HPV detection was conducted by hybridisation using GenoFlow HPV Array Test Kits (DiagCor Bioscience Inc., Hong Kong, China). EBV detection was performed using real-time PCR with an EBV PCR Kit (EBV/ISEX/100, GeneProof, Brno, Czech Republic). Results: OPSCC tumour samples obtained from women showed lower global DNA methylation levels than those from men (1.3% vs. 3.5%, p = 0.049). The margin samples from OPSCC patients with HPV and EBV coinfection showed global DNA methylation lower than those without coinfection (p = 0.042). G3 tumours from OSCC patients had significantly lower levels of global DNA methylation than G2 tumours (0.98% ± 0.74% vs. 3.77% ± 4.97%, p = 0.010). Additionally, tumours from HPV-positive OSCC patients had significantly lower global DNA methylation levels than those from HPV-negative patients (p = 0.013). In the margin samples, we observed a significant negative correlation between global DNA methylation and the N stage of OSCC patients (rS = −0.33, p = 0.039). HPV-positive OPSCC patients had higher global DNA methylation levels than HPV-positive OSCC patients (p = 0.015). Conclusion: We confirmed that methylation could be changed in relation to viral factors, such as HPV and EBV, as well as clinical and demographical parameters. [ABSTRACT FROM AUTHOR]

Abstract Background Human papillomavirus (HPV) is associated with cervical cancer and cervical dysplasia worldwide. Data on HPV prevalence in a region is important because it serves as a predictor of the likelihood of the population in that particular region acquiring cervical cancer. Moreover, with the availability of effective vaccines, the public health system must be aware of the preponderance of HPV to implement the vaccine. The present study was designed to understand the prevalence of HPV and associated factors among the women of South Andaman Island. Methods A cross-sectional study was conducted among married women of reproductive age (18–59 years) from South Andaman District from 2018 to 2022. Cervical scrapes were collected from participants after obtaining informed written consent for HPV molecular testing (HPV DNA) such as PCR assay. Demographic data was collected using a standard questionnaire and statistical analyses were performed to determine the associated factors. Results The study showed prevalence of HPV as 5.9%(95% CI: 3.9–7.9) and prevalence of HR-HPV16 was 4.1% (95% CI 2.6 – 5.5) and HR-HPV18 prevalence was 1.8(95% CI: 0.6–3). The independent factors associated the HPV positivity were age above 55 years, menopause, post-menopausal bleeding, blood-stained vaginal discharge and loss of weight. Age was associated with all HPV infections among the South Andaman women. Conclusions HPV 16 was reported as the predominant high risk HPV type circulating among women of South Andaman. Cervical cancer and precancerous lesions were significantly associated with HPV positivity and High risk HPV 16. Based on the knowledge of the risk factors associated with HPV, implementation of stronger public health awareness and prophylactic HPV vaccination is crucial among the women of this remote island.

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortality worldwide. Notably, the incidence of lung cancer among never-smokers, predominantly women, has been rising in recent years. Among the various implicated risk factors, human papilloma virus (HPV) may play a role in the development of NSCLC in a certain subset of patients. The prevalence of high-risk HPV-DNA within human neoplastic lung cells varies across the world; however, the carcinogenetic role of HPV in NSCLC has not been completely understood. Bloodstream could be one of the routes of transmission from infected sites to the lungs, along with oral (through unprotected oral sex) and airborne transmission. Previous studies reported an elevated risk of NSCLC in patients with prior HPV-related tumors, such as cervical, laryngeal, or oropharyngeal cancer, with better prognosis for HPV-positive lung cancers compared to negative forms. On the other hand, 16% of NSCLC patients present circulating HPV-DNA in peripheral blood along with miRNAs expression. Typically, these patients have a poorly differentiated NSCLC, often diagnosed at an advanced stage. However, HPV-positive lung cancers seem to have a better response to target therapies (EGFR) and immune checkpoint inhibitors and show an increased sensitivity to platinum-based treatments. This review summarizes the current evidence regarding the role of HPV in NSCLC development, especially among patients with a history of HPV-related cancers. It also examines the diagnostic and prognostic significance of HPV, investigating new future perspectives to enhance cancer screening, diagnostic protocols, and the development of more targeted therapies tailored to specific cohorts of NSCLC patients with confirmed HPV infection.

Background Viral Warts are benign proliferation of epidermis caused by Human Papilloma Virus (HPV). Different types of cutaneous warts include flat warts, palmoplantar warts, common warts, genital warts etc. Treatment options includes salicylic acid, formaldehyde, liquid nitrogen cryotherapy, trichloroacetic acid (TCA), tretinoin, potassium hydroxide (KOH) and cauterization. Objective To compare the efficacy of 10% KOH solution versus liquid nitrogen (cryotherapy) in the treatment of palmoplantar warts. Methods A total of 120 patients of palmoplantar warts fulfilling inclusion and exclusion criteria were inducted in the study. Patients were randomly divided into two groups; 60 patients in Group A received 10% KOH solution daily at night while 60 patients in Group B received treatment with liquid nitrogen cryotherapy weekly by cotton bud method. Efficacy was assessed at the end of 4 weeks for both groups. Treatment was labeled as efficacious if complete disappearance of warts occurred after 4 weeks of therapy. Results Mean age of patients was 22.97±10.69 years. Efficacy was seen in 73.3% patients in group A and 60% patients in group B. Treatment was found to be efficacious in both groups and there was no statistically significant difference in efficacy between these treatment modalities. Conclusion 10% KOH was found to be equally effective as liquid nitrogen cryotherapy in treating palmoplantar warts. [ABSTRACT FROM AUTHOR]

Simple Summary: Epstein Barr virus (EBV) is a constant companion of humans with more than 95% of the adult population being persistently infected. Fortunately, this companionship is mostly asymptomatic, but in around 300,000 new patients every year, EBV-associated cancers emerge. These medical cases are mostly caused by environmental or genetic conditions that either increase EBV-associated tumorigenesis or weaken its immune control. In this review, I will discuss co-infections as important environmental risk factors for EBV-associated malignancies and how both EBV infection but also the respective co-infections could be targeted to reduce the associated disease load. The oncogenic and persistent Epstein Barr virus (EBV) is carried by more than 95% of the human adult population. While asymptomatic in most of these, EBV can cause a wide variety of malignancies of lymphoid or epithelial cell origin. Some of these are also associated with co-infections that either increase EBV-induced tumorigenesis or weaken its immune control. The respective pathogens include Kaposi-sarcoma-associated herpesvirus (KSHV), Plasmodium falciparum and human immunodeficiency virus (HIV). In this review, I will discuss the respective tumor entities and possible mechanisms by which co-infections increase the EBV-associated cancer burden. A better understanding of the underlying mechanisms could allow us to identify crucial features of EBV-associated malignancies and defects in their immune control. These could then be explored to develop therapies against the respective cancers by targeting EBV and/or the respective co-infections with pathogen-specific therapies or vaccinations.

Background: This pilot study assesses the potential use of miRNAs in the triage of colposcopy patients with type 3 (nonvisible) cervical transformation zone (TZ). Type 3 TZ is a constitutional finding associated with many problems and controversies in colposcopy patient management. Here, we present miRNAs as a potential biomarker for the detection of CIN3 in these cases. Materials and methods: Cervical mucosa samples (CMS) were collected from patients presenting with T3 transformation zone during routine workup using the Cytobrush. Depending on the histological and cytological result, as well as the result of the routinely performed HPV PCR, patients were divided into three groups: patients with a high-grade intraepithelial lesion (CIN3) and a positive high-risk HPV test (CIN3 group), patients without an intraepithelial lesion and a positive high-risk HPV test (HPV group), and healthy controls (N = no intraepithelial lesion and negative HPV test). The cervical mucus samples included in the study were tested for their expression levels of distinct miRNAs using qPCR. Results: All investigated miRNAs were consistently detectable in every sample. The CMSs of histologically graded CIN 3 showed consistently high expression levels of all eight miRNAs, whereas the CMSs from healthy patients (N) show generally lower expression levels. However, CMSs from patients of the HPV group represented a very heterogeneous group. Conclusions: The data presented here can provide a solid basis for future research into a triage test for patients with a T3 transformation zone on the basis of commonly used clinical equipment.

The treatment of unresectable or metastatic Head and Neck Squamous Cell Carcinoma (HNSCC) has traditionally relied on chemotherapy or radiotherapy, yielding suboptimal outcomes. The introduction of immunotherapy has significantly improved HNSCC treatment, even if the long-term results cannot be defined as satisfactory. Its mechanism of action aims to counteract the blockade of tumor immune escape. This result can also be obtained by stimulating the immune system with vaccines. This review scope is to comprehensively gather existing evidence and summarize ongoing clinical trials focused on therapeutic vaccines for HNSCC treatment. The current landscape reveals numerous promising drugs in the early stages of experimentation, along with a multitude of trials that have been suspended or abandoned for years. Nonetheless, there are encouraging results and ongoing experiments that instill hope for potential paradigm shifts in HNSCC therapy.

Person-centredness is claimed to be one of the aims of healthcare, placing the person at the centre of healthcare (services). However, individual responsibility is expected and stressed in the implementation with limited structural support. This has led to the situation where despite the availability of HPV vaccination as the most beneficial preventive method, the coverage for girls aged 12â14 is below the recommended (>70%) rate. The objective of the research was to analyse structural constraints experienced by parents and service providers of the target group of girls regarding HPV vaccination under the circumstances of a global pandemic. Qualitative methods were used, namely in-depth interviews (n = 18) with nurses and midwives and three focus group interviews (n = 13) with parents of girls aged 12â14 years, as well as thematic textual analysis with the combination of inductive and deductive analysis methods. The research was granted ethical permission. The results outline that for parents the main challenge is the ability to find relevant supportive information for decision-making. For nurses, the challenge is to find appropriate ways to counsel and support parents and girls. The study revealed the lack of a country-wide strategy as one of the weak links in supporting the continuation of necessary preventive activities despite the external situation. Also, the skills of counselling and development of innovative communicative and educational digital tools that are target group specific yet also country- and culture-specific should be improved, as this may lead to more person-centred healthcare service for cervical cancer prevention.

We previously reported that REBACIN effectively eliminates persistent high-risk human papillomavirus (hrHPV) infection. Here, we conducted a prospective multicenter cohort study to evaluate the safety and effectiveness of REBACIN, taking into account factors such as specific hrHPV subtype and patient's age. According to inclusion/exclusion criteria and participant willingness, 3252 patients were divided into REBACIN group while 249 patients into control group. Patients in REBACIN group received one course treatment of intravaginal administration of REBACIN while no treatment in control group. After drug withdrawal, participants in both groups were followed up. The clearance rate of persistent hrHPV infection in REBACIN group was 60.64%, compared to 20.08% in control group. Specifically, the clearance rates for single-type infection of HPV16 or HPV18 were 70.62% and 69.23%, respectively, which was higher than that of HPV52 (59.04%) or HPV58 (62.64%). In addition, the single, double, and triple/triple+ infections had a clearance rate of 65.70%, 53.31%, and 38.30%, respectively. Moreover, 1635 patients under 40 years old had a clearance rate of 65.14%, while it was 55.08% for 1447 patients over 40 years old. No serious adverse effects were found. This study confirmed that REBACIN can effectively and safely eliminate persistent hrHPV infection, which the clearance rate of HPV16/18 is higher than that of HPV52/58, the clearance rate of single-type infection is higher than that of multiple-type infections, and the clearance rate in young patients is higher than that in elder patients, providing a guidance for REBACIN application in clearing hrHPV persistent infection in real-world settings. Chinese Clinical Trial Registry Registration Number: ChiCTR1800015617 http://www.chictr.org.cn/showproj.aspx?proj=26529 Date of Registration: 2018-04-11 • REBACIN is safe and effective for eliminating persistent high-risk HPV infection in a real-world clinical setting. • HPV16/18 is cleared more easily than HPV52/58. • Single-type infections are cleared more easily than multiple-type infections. • Young patients have a higher clearance rate than older patients. • Providing valuable guidance for clinical use of REBACIN while also suggesting potential areas for future basic research.

This study aimed to evaluate the concordance of HPV results between the SentisTM HPV assay (Sentis) (BGI Group, Shenzhen, China), an isothermal amplification-based HPV assay, on self-collected and clinician-collected samples and the agreement of Sentis on self-collected samples with the BD OnclarityTM HPV assay (Onclarity) (Becton, Dickinson, and Company, Franklin Lakes, New Jersey, USA), a PCR-based HPV assay, on clinician-collected samples. This was a prospective study of 104 women attending the colposcopy clinic for abnormal smears. After informed consent, participants self-collected vaginal samples before having clinician-collected cervical samples. Self-collected samples underwent HPV testing with Sentis (Self-Sentis HPV) and clinician-collected samples were tested with Sentis (Clinician-Sentis HPV) and Onclarity (Clinician-Onclarity), which was used as a reference standard. The concordance was assessed using Cohen's kappa. The prevalence of HPV and the acceptability of self-sampling were also evaluated. The concordance rate between Self-Sentis HPV and Clinician-Sentis HPV was 89.8% with a kappa of 0.769. The concordance rate between Self-Sentis HPV and Clinician-Onclarity was 84.4% with a kappa of 0.643. The prevalence of HPV was 26.0% on Clinician-Onclarity, 29.3% on Clinician-Sentis HPV, and 35.6% on Self-Sentis HPV. Overall, 65% of participants would undergo self-sampling again. This was attributed to mainly not feeling embarrassed (68%) and being convenient (58%). Our study showed a substantial agreement between Self-Sentis HPV with Clinician-Sentis HPV and Clinician-Onclarity. Self-sampling was also shown to be a generally well-accepted method of screening.

Objective: The clinical course of recurrent respiratory papillomatosis (RRP) varies from spontaneous remission to severe airway obstruction with wide variability in recurrence. Standard treatment involves debulking to improve voice and/or breathing. Non‐surgical therapies are emerging in hopes of non‐operative disease control. This retrospective review analyzes long‐term safety, efficacy, and durability of clinical control in the largest reported series of parenteral bevacizumab in adults with RRP. Methods: Twenty‐three patients with known RRP who have been receiving off‐label systemic bevacizumab were included. Dosage, infusion interval, number of cycles, debulking requirements, subjective outcomes, adverse events, and reasons for treatment termination were investigated. Results: Patients have been followed for an average of 791.43 (21–1468) days. The most common starting dosing regimen was 15 mg/kg at 3 weeks in 11 followed by 10 mg/kg at 6 weeks intervals in 6 individuals. Long‐term maintenance dosage varied with the least intensive regimen being 10 mg/kg at 14‐week intervals. Subjective improvement of voice and/or breathing was reported in 18/23 subjects. The median time for patients that needed a procedure after treatment was 634 days. Procedures after infusions decreased from 3.08 ± 2.48 procedures in the year prior to 0.52 ± 1.12 during systemic Bevacizumab, and to 0.86 ± 2.05 after stopping bevacizumab. Therapy termination occurred in 8 subjects where only 3 were due to adverse events. Conclusion: Parenteral bevacizumab remains a well‐tolerated treatment for patients with recalcitrant RRP. There appears to be a durable reduction in the frequency of debulking surgery requirements although on a maintenance regimen. Laryngoscope, 133:2725–2733, 2023 [ABSTRACT FROM AUTHOR]

Background: The global incidence of lip and oral cavity cancers (OCCs) and oropharyngeal cancers (OPCs) is steadily increasing. While tobacco and alcohol consumption are established risk factors, a considerable proportion of these cancers has become attributed to human papilloma virus (HPV) infection. We aimed to describe the occurrence and identify potential risk factors of OCCs and OPCs across the Russian Federation during 2007-2018. Methods: We conducted an ecological analysis using publicly accessible data from the P.A. Herzen Moscow Oncology Research Institute. Incidence and mortality rates by jurisdiction were mapped for geospatial analysis. We predefined 11 potential contributing risk factors and used univariable and multivariable Poisson regression model with backwards stepwise variable selection to identify associated factors with OCC and OPC. Results: A total of 190,585 individuals were diagnosed with OCCs and OPCs in Russia between 2007-2018. Non-uniform geographic distribution of cancer cases was noted where the Far Eastern Federal District had the highest rate of OCC and the Central Federal District of OPCs. Districts with high weekly alcohol consumption had significantly higher incidence and mortality rates in both sexes. Districts with high rates of daily smoking had higher incidence of OCC among females, and those with low smoking trends had lower mortality rates for OCCs and OPCs. Conclusion: We detail the burden of OCCs and OPCs across Russia, with the aim of elucidating modifiable risk factors and proposing evidence-based prevention strategies. Tobacco/alcohol sales control measures and smoking/drinking cessation programs should continue to be prioritized as public health measures, especially for females. [ABSTRACT FROM AUTHOR]

Background: This study characterized whether the updated AJCC 8th edition nodal staging system for p16+ oropharyngeal squamous cell carcinoma (OPSCC) resulted in the loss of prognostic value. Methods: The NCDB was queried for patients with node‐positive p16+ OPSCC. The prognostic impact of nodal size, nodal quantity, nodal laterality, and extracapsular extension (ECE) on overall survival (OS) was assessed. Results: In the clinical cohort, inferior 5‐year OS was observed in patients with more than one positive lymph node (p < 0.001; 82% vs. 86%), ECE (p < 0.001; 82% vs. 75%), or nodal size >6 cm (p < 0.001; 66% vs. 82%). In the pathologic cohort, inferior 5‐year OS was observed in patients with > four positive lymph nodes (p < 0.001; 76% vs. 90%), ECE (p < 0.001; 83% vs. 92%), or largest nodal size >6 cm (p < 0.001; 81% vs. 89%). Conclusions: Simplifications in the current p16+ OPSCC staging system led to loss of prognostic information in nodal staging. [ABSTRACT FROM AUTHOR]

A male patient in his 70s who had undergone a regular upper gastrointestinal endoscopy noted a flat, erythematous area on the right soft palate of the oropharynx 9 months after his treatment of oropharyngeal cancer. Six months after noticing the lesion, endoscopy revealed that the lesion had rapidly developed into a thick, erythematous, bump. Endoscopic submucosal dissection was performed. Pathological analysis of the resected tissue found a squamous cell carcinoma with a thickness of 1400 μm invading the subepithelial layer. There are few reports on the growth speed of pharyngeal cancer and it remains unclear. In some cases, the growth of the pharyngeal cancer may be rapid, and it is important to follow up the patient in a short period of time. [ABSTRACT FROM AUTHOR]

Person-centredness is claimed to be one of the aims of healthcare, placing the person at the centre of healthcare (services). However, individual responsibility is expected and stressed in the implementation with limited structural support. This has led to the situation where despite the availability of HPV vaccination as the most beneficial preventive method, the coverage for girls aged 12-14 is below the recommended (>70%) rate. The objective of the research was to analyse structural constraints experienced by parents and service providers of the target group of girls regarding HPV vaccination under the circumstances of a global pandemic. Qualitative methods were used, namely in-depth interviews (n = 18) with nurses and midwives and three focus group interviews (n = 13) with parents of girls aged 12-14 years, as well as thematic textual analysis with the combination of inductive and deductive analysis methods. The research was granted ethical permission. The results outline that for parents the main challenge is the ability to find relevant supportive information for decision-making. For nurses, the challenge is to find appropriate ways to counsel and support parents and girls. The study revealed the lack of a country-wide strategy as one of the weak links in supporting the continuation of necessary preventive activities despite the external situation. Also, the skills of counselling and development of innovative communicative and educational digital tools that are target group specific yet also country- and culture-specific should be improved, as this may lead to more person-centred healthcare service for cervical cancer prevention. Inimkesksust peetakse üheks tervisekorralduse eesmärgiks, mis seab inimesed tervishoiuteenuste korralduses kesksele kohale. Samas eeldab ja rõhutab inimkesksuse rakendamine individuaalse vastutuse olulisust vähese struktuurse toetuse pakkumisega. See on viinud emakakaelavähi ennetuse kontekstis olukorrani, kus 12-14-aastaste tüdrukute HPV-vaktsineeritus on alla soovitusliku 70% vaatamata sellele, et vaktsineerimine on emakakaelavähi kõige tõhusam ennetamise viis, mis on sihtrühma tüdrukutele ka tasuta kättesaadav. Globaalne COVID-19 pandeemia on üleriigiliste piirangute tõttu esile toonud uusi väljakutseid tervishoiuteenustele, sh erinevate ennetustegevuste jätkusuutlikul osutamisel. Selle uuringu eesmärk on analüüsida nii pandeemiaga seotud kui neist sõltumatuid struktuurseid piiranguid, mida sihtrühma kuuluvate tütarlaste vanemad ja teenust osutavad tervishoiutöötajad on kogenud seoses HPV vaktsineerimisega. Andmete kogumiseks kasutati kaht erinevat kvalitatiivset meetodit: süvaintervjuusid 14 tervishoiutöötajaga (õed ja ämmaemandad) ning kolme fookusgrupi intervjuud sihtrühma kuuluvate tütarlaste 13 vanemaga. Andmeid analüüsiti temaatilise tekstianalüüsi meetodil. Uuring on kooskõlastatud eetikakomitees. Tulemused osutavad, et vanematele on peamiseks väljakutseks vaktsineerimisotsuse jaoks vajaliku asjakohase informatsiooni leidmine. Tervishoiutöötajate mure on erinevate sobivate nõustamisviiside valimine tüdrukute ja nende vanemate toetamiseks. Tulemused toovad esile riikliku strateegilise kriisiplaani vajaduse, mis tagaks jätkusuutliku ennetustegevuste pakkumise sõltumata välistest tingimustest. Samuti vajavad arendamist nõustamisoskused ja sihtrühmale sobivad ning riigi- ja kultuurispetsiifiliseks kohandatud innovaatilised kommunikatsiooni- ja tervisehariduse alased lahendused, et pakkuda inimkeskset tervishoiuteenust emakakaelavähi ennetuseks.

Abstract Background The aim of this research is to analyze knowledge of adults between 18 and 45 years of age and living in the Northern Cyprus about Human Papilloma Virus (HPV) along with their attitudes and beliefs towards HPV vaccine. Materials and methods The research, which was planned as a descriptive and cross-sectional, was executed on the web. The research was completed with 1108 women and men adults between 18 and 45 years of age, living in the Northern Cyprus and volunteered to participate in the study. Results 51.90% of the adults participating in the study were found to be women, 8.84% had a Sexually transmitted disease (STD) before and 63.27% of the individuals who had a sexually transmitted disease before also had had HPV and they knew it, 77.55% had undergone a treatment for their disease, 59.18% were found to be actively infected with HPV. Statistically significant and positive correlations were determined between the overall scores of the participants from the Human Papillomavirus Knowledge Questionnaire (HPV-KQ) and their scores in the perceived severity, perceived benefits and perceived susceptibility sub-dimensions of the Health Belief Model Scale for Human Papilloma Virus and Its Vaccination (HBMS-HPVV) (p

Abstract Background Cervical cancer is the fourth most common cancer worldwide and is the most frequently diagnosed cancer in 23 countries and the most common cause of death in 36 countries, mostly from Sub-Saharan African countries. Cervical screening is a key element to reduce the incidence and mortality of cervical cancer. Cancer screening is low in Sub-Saharan Africa. This study aims to provide information about cervical premalignant lesions frequency in Somalia. Methods The pathology results of cervicovaginal smear samples obtained from patients aged 25–65 years who applied to the gynecology outpatient clinic between October 5 and December 5, 2021 were analyzed retrospectively. SPSS 22.0 was used for the statistical analysis of the data. Result Among the 497 results, 63 premalignant lesions were detected. The rate of premalignant lesions (63/497) was found to be 12.3%. The most common premalignant lesion was atypical squamous cells of undetermined significance (ASC-US). Conclusion In this study, the frequency of cervical premalignant lesions in Somalia was found to be higher than in the literature. Vaccination, screening, and early diagnosis are the most important components in the fight against cervical cancer. Access to vaccination, screening, and early diagnosis, which are the most important components in the fight against cervical cancer in Somalia, will be possible with the cooperation of the national health system and international organizations.

Human papillomavirus (HPV) is a viral infection that, if does not go away, can cause health problems like genitalwarts and cancer. The national immunization schedules for individuals before sexual debut, significantly decreased HPV-associated mortality and it will be affordable. However, immunization programs remain vulnerable to macroeconomic factors such as inflation, fiscal policy, employment levels, and national income. This review aims to investigate the association between national income in lower-middle-income countries to explore recent advances and potential issues, as well as how to deal with challenges.

The relationship among microbiome, immunity and cervical cancer has been targeted by several studies, yet many questions remain unanswered. We characterized herein the virome and bacteriome from cervical samples and correlated these findings with innate immunity gene expression in a Brazilian convenience sample of HPV-infected (HPV+) and uninfected (HPV-) women. For this purpose, innate immune gene expression data were correlated to metagenomic information. Correlation analysis showed that interferon (IFN) is able to differentially modulate pattern recognition receptors (PRRs) expression based on HPV status. Virome analysis indicated that HPV infection correlates to the presence of Anellovirus (AV) and seven complete HPV genomes were assembled. Bacteriome results unveiled that vaginal community state types (CST) distribution was independent of HPV or AV status, although bacterial phyla distribution differed between groups. Furthermore, TLR3 and IFNαR2 levels were higher in the Lactobacillus no iners-dominated mucosa and we detected correlations among RIG-like receptors (RLR) associated genes and abundance of specific anaerobic bacteria. Collectively, our data show an intriguing connection between HPV and AV infections that could foster cervical cancer development. Besides that, TLR3 and IFNαR2 seem to create a protective milieu in healthy cervical mucosa (L. no iners-dominated), and RLRs, known to recognize viral RNA, were correlated to anaerobic bacteria suggesting that they might be related to dysbiosis.

Simple Summary: According to the latest GLOBOCAN data, head and neck squamous cell carcinoma (HNSCC) represents the sixth most prevalent human malignancy. Recent studies indicate that various immune cell populations may determine the pathogenesis of HNSCCs. The aim of this review was to provide a comprehensive overview of the role of the immune response in HNSCC tumorigenesis, molecular signatures and the mechanisms regulating pro- and anti-cancer activity; it also examines their impact on the current status and future prospects of immunotherapeutic strategies for overcoming immune escape of HNSCC. The study corpus encompasses a wide range of recent molecular, observational and intervention studies on the role of immune signalling pathways and interaction between neoplastic cells and immune cells in human HNSCCs. Rapid advances in the field of immuno-oncology and the constantly growing body of knowledge concerning immunosuppressive mechanisms have allowed effective and personalized immunotherapy to be used as a first-line therapeutic procedure or an essential component of a combination therapy for primary, relapsed and metastatic HNSCC. A greater understanding of the immune response in cancers may also contribute to the further identification of new potential immunological biomarkers necessary for greater clinical benefit in HNSCC patients. Head and neck squamous cell carcinoma (HNSCC) is one of the most aggressive and heterogeneous groups of human neoplasms. HNSCC is characterized by high morbidity, accounting for 3% of all cancers, and high mortality with ~1.5% of all cancer deaths. It was the most common cancer worldwide in 2020, according to the latest GLOBOCAN data, representing the seventh most prevalent human malignancy. Despite great advances in surgical techniques and the application of modern combinations and cytotoxic therapies, HNSCC remains a leading cause of death worldwide with a low overall survival rate not exceeding 40–60% of the patient population. The most common causes of death in patients are its frequent nodal metastases and local neoplastic recurrences, as well as the relatively low response to treatment and severe drug resistance. Much evidence suggests that the tumour microenvironment (TME), tumour infiltrating lymphocytes (TILs) and circulating various subpopulations of immunocompetent cells, such regulatory T cells (CD4+CD25+Foxp3+Tregs), cytotoxic CD3+CD8+ T cells (CTLs) and CD3+CD4+ T helper type 1/2/9/17 (Th1/Th2/Th9/Th17) lymphocytes, T follicular helper cells (Tfh) and CD56dim/CD16bright activated natural killer cells (NK), carcinoma-associated fibroblasts (CAFs), myeloid-derived suppressor cells (MDSCs), tumour-associated neutrophils (N1/N2 TANs), as well as tumour-associated macrophages (M1/M2 phenotype TAMs) can affect initiation, progression and spread of HNSCC and determine the response to immunotherapy. Rapid advances in the field of immuno-oncology and the constantly growing knowledge of the immunosuppressive mechanisms and effects of tumour cancer have allowed for the use of effective and personalized immunotherapy as a first-line therapeutic procedure or an essential component of a combination therapy for primary, relapsed and metastatic HNSCC. This review presents the latest reports and molecular studies regarding the anti-tumour role of selected subpopulations of immunocompetent cells in the pathogenesis of HNSCC, including HPV+ve (HPV+) and HPV−ve (HPV−) tumours. The article focuses on the crucial regulatory mechanisms of pro- and anti-tumour activity, key genetic or epigenetic changes that favour tumour immune escape, and the strategies that the tumour employs to avoid recognition by immunocompetent cells, as well as resistance mechanisms to T and NK cell-based immunotherapy in HNSCC. The present review also provides an overview of the pre- and clinical early trials (I/II phase) and phase-III clinical trials published in this arena, which highlight the unprecedented effectiveness and limitations of immunotherapy in HNSCC, and the emerging issues facing the field of HNSCC immuno-oncology.

Chlamydia trachomatis and human papillomavirus (HPV) are the most common pathogens found in sexually transmitted infections (STIs), and both are known to increase the risk of cervical cancer (CC) and infertility. HPV is extremely common worldwide, and scientists use it to distinguish between low-risk and high-risk genotypes. In addition, HPV transmission can occur via simple contact in the genital area. From 50 to 80% of sexually active individuals become infected with both C. trachomatis and HPV viruses during their lifetime, and up to 50% become infected with an HPV oncogenic genotype. The natural history of this coinfection is strongly conditioned by the balance between the host microbiome and immune condition and the infecting agent. Though the infection often regresses, it tends to persist throughout adult life asymptomatically and silently. The partnership between HPV and C. trachomatis is basically due to their similarities: common transmission routes, reciprocal advantages, and the same risk factors. C. trachomatis is a Gram-negative bacteria, similar to HPV, and an intracellular bacterium, which shows a unique biphasic development that helps the latter continue its steady progression into the host throughout the entire life. Indeed, depending on the individual's immune condition, the C. trachomatis infection tends to migrate toward the upper genital tract and spread to the uterus, and the fallopian tubes open up a pathway to HPV invasion. In addition, most HPV and C. trachomatis infections related to the female genital tract are facilitated by the decay of the first line of defense in the vaginal environment, which is constituted by a healthy vaginal microbiome that is characterized by a net equilibrium of all its components. Thus, the aim of this paper was to highlight the complexity and fragility of the vaginal microenvironment and accentuate the fundamental role of all elements and systems involved, including the Lactobacillus strains (Lactobacillus gasseri, Lactobacillus jensenii, Lactobacillus crispatus) and the immune–endocrine system, in preserving it from oncogenic mutation. Therefore, age, diet, and genetic predisposition together with an unspecific, persistent low-grade inflammatory state were found to be implicated in a high frequency and severity grade of disease, potentially resulting in pre-cancerous and cancerous cervical lesions.

BackgroundThe global incidence of lip and oral cavity cancers (OCCs) and oropharyngeal cancers (OPCs) is steadily increasing. While tobacco and alcohol consumption are established risk factors, a considerable proportion of these cancers has become attributed to human papilloma virus (HPV) infection. We aimed to describe the occurrence and identify potential risk factors of OCCs and OPCs across the Russian Federation during 2007-2018.MethodsWe conducted an ecological analysis using publicly accessible data from the P.A. Herzen Moscow Oncology Research Institute. Incidence and mortality rates by jurisdiction were mapped for geospatial analysis. We pre-defined 11 potential contributing risk factors and used univariable and multivariable Poisson regression model with backwards stepwise variable selection to identify associated factors with OCC and OPC.ResultsA total of 190,585 individuals were diagnosed with OCCs and OPCs in Russia between 2007-2018. Non-uniform geographic distribution of cancer cases was noted where the Far Eastern Federal District had the highest rate of OCC and the Central Federal District of OPCs. Districts with high weekly alcohol consumption had significantly higher incidence and mortality rates in both sexes. Districts with high rates of daily smoking had higher incidence of OCC among females, and those with low smoking trends had lower mortality rates for OCCs and OPCs.ConclusionWe detail the burden of OCCs and OPCs across Russia, with the aim of elucidating modifiable risk factors and proposing evidence-based prevention strategies. Tobacco/alcohol sales control measures and smoking/drinking cessation programs should continue to be prioritized as public health measures, especially for females.

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortality worldwide. Notably, the incidence of lung cancer among never-smokers, predominantly women, has been rising in recent years. Among the various implicated risk factors, human papilloma virus (HPV) may play a role in the development of NSCLC in a certain subset of patients. The prevalence of high-risk HPV-DNA within human neoplastic lung cells varies across the world; however, the carcinogenetic role of HPV in NSCLC has not been completely understood. Bloodstream could be one of the routes of transmission from infected sites to the lungs, along with oral (through unprotected oral sex) and airborne transmission. Previous studies reported an elevated risk of NSCLC in patients with prior HPV-related tumors, such as cervical, laryngeal, or oropharyngeal cancer, with better prognosis for HPV-positive lung cancers compared to negative forms. On the other hand, 16% of NSCLC patients present circulating HPV-DNA in peripheral blood along with miRNAs expression. Typically, these patients have a poorly differentiated NSCLC, often diagnosed at an advanced stage. However, HPV-positive lung cancers seem to have a better response to target therapies (EGFR) and immune checkpoint inhibitors and show an increased sensitivity to platinum-based treatments. This review summarizes the current evidence regarding the role of HPV in NSCLC development, especially among patients with a history of HPV-related cancers. It also examines the diagnostic and prognostic significance of HPV, investigating new future perspectives to enhance cancer screening, diagnostic protocols, and the development of more targeted therapies tailored to specific cohorts of NSCLC patients with confirmed HPV infection.

Background: This pilot study assesses the potential use of miRNAs in the triage of colposcopy patients with type 3 (nonvisible) cervical transformation zone (TZ). Type 3 TZ is a constitutional finding associated with many problems and controversies in colposcopy patient management. Here, we present miRNAs as a potential biomarker for the detection of CIN3 in these cases. Materials and methods: Cervical mucosa samples (CMS) were collected from patients presenting with T3 transformation zone during routine workup using the Cytobrush. Depending on the histological and cytological result, as well as the result of the routinely performed HPV PCR, patients were divided into three groups: patients with a high-grade intraepithelial lesion (CIN3) and a positive high-risk HPV test (CIN3 group), patients without an intraepithelial lesion and a positive high-risk HPV test (HPV group), and healthy controls (N = no intraepithelial lesion and negative HPV test). The cervical mucus samples included in the study were tested for their expression levels of distinct miRNAs using qPCR. Results: All investigated miRNAs were consistently detectable in every sample. The CMSs of histologically graded CIN 3 showed consistently high expression levels of all eight miRNAs, whereas the CMSs from healthy patients (N) show generally lower expression levels. However, CMSs from patients of the HPV group represented a very heterogeneous group. Conclusions: The data presented here can provide a solid basis for future research into a triage test for patients with a T3 transformation zone on the basis of commonly used clinical equipment.

Abstract Objective To evaluate whether the presence of human papillomavirus (HPV) DNA and p16 might be associated with better prognosis in patients with hypopharyngeal carcinoma (HPC), especially on overall survival (OS) and disease-free survival (DFS). Method PubMed, the Cochrane Library, the Web of Science and EMBASE were searched from inception to April 2021 to search for HPV DNA- and p16-related prognostic articles on HPC. Meta-analysis was performed on the selected articles according to the inclusion and exclusion criteria. Publication bias was assessed for the included studies with Egger’s test. All studies were analyzed by using Stata 16.0 statistical software. Results A total of 18 studies were included, including 12 HPV DNA studies and 11 p16 studies. Meta-analysis showed that HPV DNA positivity was a strong prognostic factor for improved OS in patients with HPC, with a pooled hazard ratio (HR) of 0.61 (95% CI, 0.54–0.69), but there was no statistically significant difference in DFS (HR, 0.60; 95% CI, 0.31–1.16). Patients with p16-positive tumors had better OS (HR, 0.66; 95% CI, 0.49–0.89) and DFS (HR, 0.59; 95% CI, 0.44–0.78) than patients with p16-negative tumors. Conclusions This study suggests that the presence of HPV DNA leads to better OS in patients with HPC, and the presence of p16 also corresponds to better OS and DFS. Our results provide up-to-date evidence to clinicians and researchers. Larger studies adjusting for prognostic factors are needed in subsequent studies.

Oral squamous cell carcinoma (OSCC) is a highly invasive and pervasive human oral neoplasia, accounting for approximately 90% of all oral cavity carcinomas worldwide. Despite technological advancements, tumor spread and consequent relapse result in meagre 5- year survival rates of less than 60%. Metastasis is the culmination of a multiphase transition, characterized as epithelial-to-mesenchymal transition (EMT), which stipulates gradual acquisition of migratory phenotype in epithelial cells. Physiologically, EMT is a transient and a dynamic phenomenon underlying wound healing. However, chronic exposure of oral epithelium to multiple irritants and pathogens such as high risk-human papillomavirus (HR-HPV), causes EMT to be predominantly stimulated leading to metastatic and/or recurrent OSCC. The dreadful clinical manifestations, together with our growing understanding of EMT in carcinogenesis has prompted us to conduct a comprehensive literature review on EMT in OSCC, addressing issues such as the disruption of intercellular junctions and cytoskeleton, idiosyncratic behavior of cellular markers and signaling pathways, and tumoral microvascular environment involving inflammatory cytokines, with an insight into the role of HPV infection as a model risk factor in OSCC.

Background: The aim of this research is to analyze knowledge of adults between 18 and 45 years of age and living in the Northern Cyprus about Human Papilloma Virus (HPV) along with their attitudes and beliefs towards HPV vaccine.

Statistically significant and positive correlations were determined between the overall scores of the participants from the Human Papillomavirus Knowledge Questionnaire (HPV-KQ) and their scores in the perceived severity, perceived benefits and perceived susceptibility sub-dimensions of the Health Belief Model Scale for Human Papilloma Virus and Its Vaccination (HBMS-HPVV) (p < 0.05). There was a statistically significant and negative correlation between HPV-KQ scores, questions on Current HPV Vaccination Program and the perceived barriers sub-dimension of the HBMS-HPVV whereas there was a statistically significant and positive correlation between the HPV-KQ scores, questions on Current HPV Vaccination Program and the perceived benefits and perceived susceptibility sub-dimensions of the HBMS-HPVV (p < 0.05). Conclusions: It has emerged that the participants do not have enough information about HPV, they do not know the ways and symptoms of protection from HPV, they do not have enough information about early diagnosis and screening, and they know very little about the HPV vaccine. Health policies should be developed to increase the awareness of individuals about HPV, to increase education and to provide free vaccines. [ABSTRACT FROM AUTHOR]

There is a growing need to better understand the risk of malignancy in the multiple sclerosis (MS) population, particularly given the relatively recent and widespread introduction of immunomodulating disease modifying therapies (DMTs). Multiple sclerosis disproportionately affects women, and the risk of gynecological malignancies, specifically cervical pre-cancer and cancer, are of particular concern. The causal relationship between persistent human papillomavirus (HPV) infection and cervical cancer has been definitively established. To date, there is limited data on the effect of MS DMTs on the risk of persistent HPV infection and subsequent progression to cervical pre-cancer and cancer. This review evaluates the risk of cervical pre-cancer and cancer in women with MS, including the risk conferred by DMTs. We examine additional factors, specific to the MS population, that alter the risk of developing cervical cancer including participation in HPV vaccination and cervical screening programs.

Simple Summary: Human Papilloma Virus (HPV) is known to affect thousands globally. HPV infection can act carcinogenically on host cells with expression of the virus's E6 and E7 oncoproteins. Within the United States, roughly 70% of oropharyngeal cancers are thought to be HPV induced. Viral genome integration has been well studied, yet genomic effects of the E6 and E7 proteins on other genetic regions remain relatively unidentified. This study characterizes genomic mutation in HPV-infected HNSCC patients with specific regard to host E6 and E7 expression. Individuals with greater presence of these oncoproteins were found to exhibit a greater average of point mutations, particularly on chromosomes 1, 11, and 17. Greater expression of E6 and E7 also correlates to a lesser number of clustered variation events and fewer repeats of copy number segments. Analysis of the genomic effects of HPV may provide additional insight into the pathogenesis of HNSCC. Human Papilloma Virus (HPV) is highly prevalent within the U.S., with studies estimating that over 80% of individuals will contract the virus in their lifetime. HPV is considered a primary risk factor for the development and progression of oropharyngeal cancers. The impact of the HPV virus's E6 and E7 oncoproteins on cellular signaling pathways and genomic integration has been extensively characterized. Indirect genomic effects; however, remain relatively unidentified. In this study, we analyzed 83 HPV+ Head and Neck Squamous Cell Carcinoma (HNSCC) patients of varying HPV types. Expression counts of the HPV E6 and E7 oncogenes were estimated across samples and correlated with genomic mutational classes. High expression of E6 and E7 oncoproteins was associated with a greater number of total point mutations, especially on chromosomes 1, 11, and 17, which have been implicated in HPV-mediated cancers in previous studies. Samples with high E6 and E7 expression also exhibited more frequent non-clustered structural variation and a lack of clustered variation altogether. Copy number segments were present with fewer number of repeats in high E6 and E7 expression samples, which is known to correlate with decreased expression of affected genes. E6 and E7 expression was associated with increased activity of several cellular pathways associated in oncogenesis and telomere maintenance. In comprehensively characterizing the effects of the HPV oncoproteins on the human genome, potential mechanisms of HNSCC pathogenesis may be further elucidated. [ABSTRACT FROM AUTHOR]

Previous studies have demonstrated that REBACIN® intervention eliminates persistent high-risk human papillomavirus (hrHPV) infection. The initial establishment and subsequent progression of cervical cancer mainly depends on two major oncogenes, E6/E7, and previous studies have proposed E6/E7 oncogenes as a target for therapeutic drug development. The aim of this study was to investigate in vitro and in vivo whether REBACIN® inhibits E6/E7 oncogenes for elucidating the mechanism of REBACIN® in the clearance of persistent hrHPV infection. In vitro, after REBACIN® treatment, the growth of both Ca Ski and HeLa cervical cancer cells containing the E6/E7 oncogenes was prevented. In line with this finding is that E6/E7 expression was inhibited, which can be counteracted by the co-application of anti-REBACIN® antibody. These studies demonstrated that REBACIN® can effectively inhibit the growth of cervical cancer cells via targeting HPV E6/E7 expression. To further verify this finding in clinic, 108 volunteer patients with persistent hrHPV infections were randomly divided into REBACIN®, recombinant human interferon alpha-2b (Immunological drug control), or no-treatment blank control groups, received intravaginal administration of REBACIN®, interferon or no-treatment every other day for three months, and then followed up for E6/E7 mRNA assay. In REBACIN® group, 68.57% of patients showed complete clearance of HPV E6/E7 mRNA, which was significantly higher compared to 25.00% in the interferon immunological drug control group and 20.00% in blank control group, confirming that REBACIN® is potently efficacious on clearing persistent hrHPV infections via inhibition of HPV E6/E7 oncogenes.

This study aimed to evaluate the concordance of HPV results between the SentisTM HPV assay (Sentis) (BGI Group, Shenzhen, China), an isothermal amplification-based HPV assay, on self-collected and clinician-collected samples and the agreement of Sentis on self-collected samples with the BD OnclarityTM HPV assay (Onclarity) (Becton, Dickinson, and Company, Franklin Lakes, New Jersey, USA), a PCR-based HPV assay, on clinician-collected samples. This was a prospective study of 104 women attending the colposcopy clinic for abnormal smears. After informed consent, participants self-collected vaginal samples before having clinician-collected cervical samples. Self-collected samples underwent HPV testing with Sentis (Self-Sentis HPV) and clinician-collected samples were tested with Sentis (Clinician-Sentis HPV) and Onclarity (Clinician-Onclarity), which was used as a reference standard. The concordance was assessed using Cohen’s kappa. The prevalence of HPV and the acceptability of self-sampling were also evaluated. The concordance rate between Self-Sentis HPV and Clinician-Sentis HPV was 89.8% with a kappa of 0.769. The concordance rate between Self-Sentis HPV and Clinician-Onclarity was 84.4% with a kappa of 0.643. The prevalence of HPV was 26.0% on Clinician-Onclarity, 29.3% on Clinician-Sentis HPV, and 35.6% on Self-Sentis HPV. Overall, 65% of participants would undergo self-sampling again. This was attributed to mainly not feeling embarrassed (68%) and being convenient (58%). Our study showed a substantial agreement between Self-Sentis HPV with Clinician-Sentis HPV and Clinician-Onclarity. Self-sampling was also shown to be a generally well-accepted method of screening.
