RESUMO

INTRODUCTION: In Denmark, where human papillomavirus (HPV) -based cervical cancer screening is being implemented, the aim of this pilot implementation study was to test a specific screening algorithm, assess follow-up examination attendance, and measure the proportion of precancer lesions found in relation to the number of women referred for colposcopy. MATERIAL AND METHODS: From May 2017 to December 2020, 36 417 women in the uptake area of the Department of Pathology, Vejle Hospital, Region of Southern Denmark, were included in the HPV group. Women positive for HPV16/18 irrespective of cytology and women positive for other high-risk HPV (hrHPV) types having concomitant abnormal cytology were referred directly to colposcopy. Women positive for other hrHPV types and normal cytology were referred to repeat screening after 12 months, and hrHPV negative to routine screening after three years. We obtained information on screening results and subsequent histological diagnosis from the Danish Pathology Databank through September 2022. RESULTS: 3.6% of the women were referred to colposcopy after primary screening, 5% to repeat screening after 12 months, and 91.4% back to routine screening. High follow-up rates were observed: 96% attended colposcopy after primary screening, with 91% attending colposcopy after repeat screening. CIN3+ was detected at colposcopy following the primary screening in 28.1% of HPV16/18-positive women and 18.2% of those positive for other hrHPV types with concomitant abnormal cytology. Of the women with other hrHPV and simultaneous ASCUS/LSIL, 8% had CIN3+. At the repeat screening, 43% had become hrHPV negative, 55% were persistently positive for other hrHPV, and 2% had turned positive for HPV16/18. At the colposcopy following repeat screening, 10.1% of the women positive for other hrHPV were diagnosed with CIN3+, in comparison with 11.1% of the HPV16/18-positive women. CONCLUSIONS: In this pilot implementation study, an algorithm for HPV-based screening was evaluated in a Danish setting. The results demonstrated high attendance at follow-up examinations and provided insights into the number of colposcopy referrals and the detection of CIN2 and CIN3+ cases. The results suggest that women testing positive for other hrHPV in combination with ASCUS/LSIL at primary screening could potentially be referred to repeat screening instead of an immediate colposcopy.

RESUMO

OBJECTIVE: In 2014 the Affordable Care Act expanded Medicaid coverage in states that opted to participate. Limited data are available describing the effect of Medicaid expansion on cancer screening. The objective of our study was to evaluate trends in cervical cancer screening associated with Medicaid expansion. METHODS: Using data from the Behavioral Risk Factor Surveillance System, we identified female respondents ages 30-64 years with a household income below $35,000. The outcome measure was guideline-adherent cervical cancer screening. The years 2010 and 2012 constituted the pre-expansion period while 2016 and 2018 were used to capture the post-expansion period. A difference-in-difference (DID) analysis was performed to assess changes in cervical cancer screening in Medicaid expansion states compared to non-expansion states, for the overall sample and for each expansion state individually. RESULTS: The overall DID analysis showed a greater increase in cervical cancer screening by 1.1 percentage points (95% CI: 0.1 to 2.0%, P = 0.03) in expansion states compared to non-expansion states. The analysis comparing individual expansion states to non-expansion states showed that 6 expansion states had a significantly higher increase in screening relative to non-expansion states: Oregon (8.5%, P < 0.001), Kentucky (4.5%, P = 0.001), Washington (4.2%, P = 0.002), Colorado (4.3%, P = 0.008), Nevada (4.7%, P = 0.048), and Ohio (2.8%, P = 0.03). Of these states, 5 ranked among the states with the lowest baseline screening rates. CONCLUSIONS: Medicaid expansion states experienced a greater increase in cervical cancer screening relative to non-expansion states. Expansion states with lower baseline screening rates experienced greater increases in screening after expanding Medicaid.

RESUMO

BACKGROUND: Several types of human papillomavirus (HPV) vaccines have been approved for use in adolescent girls in China. These vaccines are regulated as non-National Immunisation Program vaccines and are optional and generally fully self-paid by vaccinees. OBJECTIVE: To assess parents' demand for HPV vaccination by eliciting their willingness-to-pay for their adolescent daughters to be vaccinated against HPV and to examine the determinants of demand for HPV vaccination in China. METHODS: A contingent valuation survey was conducted across three cities in Shandong Province in eastern China. We selected 11 junior middle schools with different socioeconomic features and randomly selected 6 classes in each school, and questionnaires were distributed to all girls aged 12-16 in the 66 classes for their parents to complete. A payment card approach was used to elicit parental willingness-to-pay for HPV vaccination for their daughters. We also collected a wide array of socioeconomic and psychological variables and interval regressions were applied to examine the determinants of parental willingness-to-pay. RESULTS: A total of 1074 eligible parents who completed valid questions were included in analyses. Over 85% of parents believed HPV vaccines were, in general, necessary and beneficiary. However, only around 10% believed that their daughters would be infected by HPV. About 8% of parents would not accept HPV vaccine even if the vaccine were free mainly due to concerns about the potential side effects and vaccine safety and quality issues, and 27.37% would only accept the vaccine if it were free. The median willingness-to-pay was 300 CNY (42 USD). Several factors were positively correlated with higher willingness-to-pay: income, urban residence (relative to rural residence), mothers (relative to fathers), parents' beliefs about vaccine benefits, whether they should make decisions for their daughters, and whether their daughters would be susceptible to HPV. Though education-level was not significantly correlated with willingness-to-pay in the main regressions, a subgroup analysis revealed interesting dynamics in the relation between education and willingness-to-pay across different income-levels. CONCLUSIONS: There is a large gap between parents' willingness-to-pay and the market price of HPV vaccine for girls in China. Parents generally believed the HPV vaccines were beneficial and necessary but when asked for their daughters, most parents did not believe their daughters would be infected by HPV despite the high prevalence in China. Future focus should be on ensuring the provision of accurate health information about HPV prevalence, vaccine quality, and safety to promote vaccine uptake, and promotional efforts tailored to different income groups might yield better effects. Government involvement in negotiating more widely acceptable and affordable prices or subsidising may be necessary for protecting high-risk population groups.

RESUMO

Denmark, alongside other Scandinavian countries, the United States, Canada, and the United Kingdom, has high prevalence of human papillomavirus (HPV). Our oropharyngeal squamous cell carcinoma (OPSCC) database includes all diagnosed cases in Eastern Denmark during a period of more than two decades. We investigated the incidence, survival, and recurrence of patients with OPSCC with combined p16- and HPV testing covering a consecutive 21-year period. Age-adjusted incidence rate (AAIR) per 100,000, survival models, and Cox proportional-hazards model were employed. Two thousand eight hundred thirty-four patients were included (57.5% HPV positive (HPV+)/p16 positive (p16+), 33.7% HPV negative (HPV-)/p16 negative (p16-), 4% HPV+/p16-, and 4.8% HPV-/p16+). The AAIR for all patients increased from 1.8 to 5.1 per 100,000 from 2000 to 2020 linked to an increasing AAIR of HPV+/p16+ OPSCCs from 0.9 to 3.5 per 100,000 from 2000 to 2020. The AAIR for the HPV-/p16- OPSCCs decreased from 1.6 to 1.4 from 2017 to 2020. HPV+/p16+ OPSCCs had a higher 5-year overall survival (OS) of 79.2% compared to the other subgroups (HPV+/p16- OS: 50.4%; HPV-/p16+ OS: 49.4%; HPV-/p16- OS: 35.1%). The AAIR of the total OPSCC group increased from year 2000 to 2020, driven by a rise in the HPV+/p16+ group. A decreasing incidence rate was observed for the HPV-/p16- OPSCCs from 2017 to 2020. The OS for HPV+/p16+ OPSCCs was significantly higher compared to all other HPV/p16 subgroups. Therefore, we recommend testing for combined HPV and p16 status in patients with OPSCC when selecting patients for clinical trials, especially in case of de-escalating/escalating.

RESUMO

INTRODUCTION: The lifetime prevalence of human papillomavirus infection (HPV) is estimated to be around 80% and it is the most common sexually transmitted infection. Despite being well known for its oncologic relevance, it has been associated with adverse pregnancy outcomes, though available evidence is contradicting. Previous meta-analyses involved articles which based HPV infection on Pap smear results, leading to a significant source of bias. Therefore, we aimed to assess the burden of genetically proven HPV infection on adverse pregnancy outcomes. MATERIAL AND METHODS: In our meta-analysis, pregnant women tested for HPV DNA were only considered eligible. We conducted a systematic search in three major databases (PubMed, Embase, and CENTRAL) on September 22, 2023. Cohort, cross-sectional, and case-control studies were eligible for the analysis. The exposed group consisted of HPV-infected patients. We assessed the odds ratios (OR) with a confidence interval (CI) of 95%. In order to reduce the heterogeneity, we performed subgroup analyses based on different strains (high risk HPV, HPV 16/18, study design). The study was prospectively registered on PROSPERO (CRD42022370228). RESULTS: Our study involved 14 articles with 7008 women. A significant association was found between preterm delivery and HPV infection (OR: 1.94, CI: 1.31-2.87). No significant association was found when separately examining high-risk HPV-infected women (OR: 1.94, CI: 0.82-4.59), and HPV 16 or 18-infected women (OR: 2.08, CI: 0.50-8.63) in terms of preterm delivery. No significant association was found between spontaneous abortion and HPV infection (OR: 1.02, CI: 0.16-6.31). CONCLUSIONS: Our analysis indicates an association between HPV infection and preterm delivery. It is imperative that future studies consider confounding variables more comprehensively. Additionally, the global implementation of HPV vaccination programs holds significance not only in oncology but also in obstetrics.

RESUMO

BACKGROUND: Papilloma DNA virus which is most common sexually transmitted disease to both sexes. The infection either benign or malignant affecting head and neck region. AIM OF THE STUDY: Assess the level of knowledge, and attitude, of medical students about Human Papilloma virus, vaccine, and its role in head and neck cancer development. MATERIALS AND METHODS: A descriptive cross-sectional survey was conducted on 357 undergraduate medical students. Data were collected by online Google form researcher made questionnaires which was analyzed using SPSS 25. RESULTS: There are 357 medical undergraduate students from different educational stages participated in this study. This study was shown 176 (49.3 %) of medical students agreed that smoking Tobacco are the most common causes for development oral cancer followed by viruses 98 (27.5 %), that 57.4 % of medical students reported that HPV was the main viral cause. As for the questions concerning HPV mode of transmission, almost (85.7 %) stated sexual transmission, (79.8 %) skin to skin direct contact. Most of the participants (92.2 %) agreed that primary prevention can decrease the risk of infection with HPV, and 43.4 % strongly agreed that vaccination plays an important role in HPV prevention. CONCLUSIONS: There is a requirement within the existing curriculum and syllabus to include more education, seminars, and training courses on HPV, role in HNC, prevention, and vaccination, and mainly for students in the preclinical academic years. Application of a virtual classroom viral module or communicating workshop would likely improve knowledge and attitudes of the students for their future medical tasks.

RESUMO

This report summarizes incidence rates and trends of sexually transmitted infections (STIs) from 2015 through 2023 among active component service members of the U.S. Armed Forces. The data compiled for this report are derived from the medical surveillance of chlamydia, gonorrhea, and syphilis as nationally notifiable diseases. Case data for 2 additional STIs, human papilloma virus (HPV) and genital herpes simplex virus (HSV), are also presented. The crude total case rates of chlamydia and gonorrhea initially rose by an average of 6.7% and 9.8% per year, respectively, until 2019. From 2020 onwards, rates steadily declined. By 2023, chlamydia rates had dropped by approximately 39%, while gonorrhea rates had fallen by more than 40% for female, and 19% for male, service members. Initially syphilis increased, on average, 10% annually from 2015 to 2019, then declined in 2020, but resumed its upward trend through 2023, nearly doubling the 2015 rate in 2023. The total crude annual incidence rates of genital HPV and HSV exhibited downward trends in general over the surveillance period, decreasing by 30.7% and 24.7%, respectively. Age- and gender-adjusted case rates for chlamydia, gonorrhea, and syphilis remain elevated within the U.S. Armed Forces compared to the general U.S. population, which may be due to factors that include mandatory STI screening, more complete reporting, incomplete adjustment for age distribution, and inequitable comparisons between the military active duty and general U.S. populations. Social restrictions enacted during the COVID-19 pandemic may have contributed to declines in true case rates and screening coverage.

RESUMO

INTRODUCTION: Giant condylomata acuminatum (GCA) also referred to as Buschke-Lowenstein tumor (BLT) is a rare tumor primarily associated with low-risk HPV 6 and 11, which is believed to be a slow growing intermediate tumor with low potential to transform into invasive cancer. CASE PRESENTATION: We presented our experience with three cases of BLT (one woman and two men). CLINICAL DISCUSSION: The three patients had surgical excision and two of them had reconstruction of the surgical defect with good clinical outcome. CONCLUSION: We highlighted the importance of early identification of symptoms, treatment options and risk of recurrence as well as primary preventive strategies.

RESUMO

OBJECTIVE: Enicostemma hyssopifolium (E. hyssopifolium) contains several bioactive compounds with anti-cancer activities. This study was performed to investigate the molecular effects of E. hyssopifolium on HPV18-containing HeLa cells. METHODS: The methanol extract of E. hyssopifolium whole plant was tested for cytotoxicity by MTT assay. A lower and higher dose (80 and 160 µg/mL) to IC50 were analyzed for colonization inhibition (Clonogenic assay), cell cycle arrest (FACS analysis), and induction of apoptosis (AO/EtBr staining fluorescent microscopy and FACS analysis) and DNA fragmentation (comet assay). The HPV 18 E6 gene expression in treated cells was analyzed using RT-PCR and qPCR. RESULTS: A significant dose-dependent anti-proliferative activity (IC50 - 108.25±2 µg/mL) and inhibition of colony formation cell line were observed using both treatments. Treatment with 80 µg/mL of extract was found to result in a higher percent of cell cycle arrest at G0/G1 and G2M phases with more early apoptosis, while 160 µg/mL resulted in more cell cycle arrest at SUBG0 and S phases with late apoptosis for control. The comet assay also demonstrated a highly significant increase in DNA fragmentation after treatment with 160 µg/mL of extract (tail moments-19.536 ± 17.8), while 80 µg/mL of extract treatment showed non-significant tail moment (8.152 ± 13.0) compared to control (8.038 ± 12.0). The RT-PCR and qPCR results showed a significant reduction in the expression of the HPV18 E6 gene in HeLa cells treated with 160 µg/mL of extract, while 80 µg/mL did not show a significant reduction. CONCLUSION: The 160 µg/mL methanol extract of E. hyssopifolium demonstrated highly significant anti-cancer molecular effects in HeLa cells.

RESUMO

There are more than 207 types of Human Papillomavirus (HPV), most of which do not cause symptoms, lesions, or warts, and cause more than 600,000 cases of cancer annually. Purpose:This study was planned to elucidate the relationship between individuals' HPV knowledge, attitudes towards the HPV vaccine, and vaccine hesitancy. The research was conducted with 1011 people using a descriptive and correlational research design. Data collection tools included socio-demographic information survey, HPV Knowledge Scale, Carolina HPV Vaccination Attitudes Scale, and Vaccine Hesitancy Scale. The data was analyzed using the SPSS 26.0 package program. The average score was 11.68±7.23 on the HPV Knowledge Scale, 30.76±7.31 on the HPV Vaccine Attitude Scale, and 27.90±11.10 on the Vaccine Hesitancy Scale. While there was a very weak negative relationship between the participants HPV knowledge and HPV Vaccine Attitude scores, a weak positive relationship was found with vaccine hesitancy. A weak positive relationship was also detected between vaccine attitude and vaccine hesitancy (p<0.05). According to the regression model created in the study, HPV vaccination attitude was explained by the HPV Knowledge Scale and vaccine hesitancy at a rate of 22.5%. In line with the results, healthcare professionals need to raise awareness in the society and increase vaccination rates.


Il existe plus de 207 types de papillomavirus humain (HPV), dont la plupart ne causent pas de symptômes, de lésions ou de verrues, mais entraînent plus de 600 000 cas de cancer chaque année. Objectif : Cette étude a été planifiée pour élucider la relation entre les connaissances des individus sur le HPV, leurs attitudes envers le vaccin contre le HPV et l'hésitation vaccinale. La recherche a été menée auprès de 1011 personnes en utilisant un plan de recherche descriptif et corrélationnel. Les outils de collecte de données comprenaient un sondage d'informations sociodémographiques, l'Échelle de Connaissances sur le HPV, l'Échelle des Attitudes envers la Vaccination contre le HPV de la Caroline et l'Échelle d'Hésitation Vaccinale. Les données ont été analysées à l'aide du programme SPSS 26.0. Le score moyen était de 11,68 ± 7,23 à l'Échelle de Connaissances sur le HPV, de 30,76 ± 7,31 à l'Échelle des Attitudes envers la Vaccination contre le HPV, et de 27,90 ± 11,10 à l'Échelle d'Hésitation Vaccinale. Bien qu'il y ait eu une très faible relation négative entre les connaissances des participants sur le HPV et les scores d'attitude envers le vaccin contre le HPV, une faible relation positive a été trouvée avec l'hésitation vaccinale. Une faible relation positive a également été détectée entre l'attitude envers la vaccination et l'hésitation vaccinale (p<0,05). Selon le modèle de régression créé dans l'étude, l'attitude envers la vaccination contre le HPV était expliquée par l'Échelle de Connaissances sur le HPV et l'hésitation vaccinale à un taux de 22,5 %. Conformément aux résultats, les professionnels de la santé doivent sensibiliser la société et augmenter les taux de vaccination.

RESUMO

Introduction: Routine human papillomavirus (HPV) vaccination in the US is recommended at ages 11 or 12 years and can be given at age 9. Vaccination completion rates among adolescents 13-15 years in the US remain below the 80% goal. This study evaluated the long-term effects of increasing proactive HPV vaccination initiation rates at age 9 years in completion rates of adolescents. Methods: An age-structured vaccination model was developed and parametrized based on the National Immunization Survey-Teen (NIS-Teen) survey data. The model projected vaccination coverage (by vaccination status and age group), for 20 years, for a routine initiation scenario (no increase in initiation rates of 9-year-olds) and different proactive initiation (increased age 9 initiation) scenarios. The time to reach a completion rate of 80% for 13-15-year-olds was estimated. The model also generated projections stratified for subgroups of interest. Results: Results indicated that vaccine completion rates of 80% in 13-15-year-olds may not be achieved by 2040 under current trends of routine initiation at ages 11 or 12 years. However, increasing initiation rates in 9-year-olds by 1% and 3% annually could shorten the time to achieve 80% completion by 4 and 8 years, respectively. Stratification analyses showed that increasing initiation rates in 9-year-olds can also reduce disparities across subgroups in the time to achieve vaccination completion targets. Discussion: Increasing HPV vaccination initiation rates in 9-year-olds by as little as 1%-3% annually may be an effective strategy to improve HPV vaccination completion rates in adolescents by age 15 and reach the Healthy People goal of 80% completion much earlier.

RESUMO

Cancer is a disease in which abnormal cells divide uncontrollably, destroying tissues. A malignant tumor arises from cells in the cervix, the lower portion of the uterus (womb) that links the uterus to the vagina (birth canal), and is known as cervical cancer. One of the most significant global community health problems is cancer, which sees a daily increase in the number of sufferers. Therefore, it is crucial to expand our understanding of the molecular pathophysiology of cervical cancer and to suggest new therapeutic goals as well as new techniques for early detection of the illness. Since early diagnosis of pathologies can dramatically increase a patient's chance of survival, prognosis, and recurrence. This article aims to educate readers about some essential concepts surrounding cervical cancer, including the various types of cervical cancer, the stages of cancer, as well as their etiology, epidemiology, pathogenesis, management, and treatment, and its relationship with pregnancy. All of these concepts are essential for any individual studying medicine or working in the medical industry to understand. We intend to summarize the information that is currently available and the recommended courses of action for treating cervical cancer and its association with pregnancy in this review. Research priorities and controversies are also noted.

RESUMO

Multiple primary malignancies (MPMs) occur when an individual develops two or more distinct primary cancers. These are categorized as synchronous or metachronous based on the timing of their diagnosis. Patients previously diagnosed with cancer face increased risks due to exposure to carcinogenic factors and treatments such as chemotherapy and radiotherapy. Individuals with a history of breast cancer are known to have elevated risks for secondary malignancies compared to the general population. However, cases of squamous cell carcinoma (SCC) of the eyelid in this group are exceedingly rare. Here, we present a case report describing a young female patient who sequentially developed metachronous breast cancer, and a human papillomavirus (HPV)-associated SCC of the eyelid. To the best of our knowledge, this case report represents the first documented instance of this specific combination of primary neoplasms in medical literature.

RESUMO

Objective: Providing the human papillomavirus (HPV) vaccine is effective to eliminate the disparity in HPV-related cancers. It is unknown regarding inequality in the distribution of HPV vaccination in China since the vaccine was licensed and approved for use in 2016. This study aimed to examine socioeconomic inequalities in HPV-related knowledge and vaccination and identified factors associated with such inequalities. Methods: Self-administered questionnaires measuring HPV-related knowledge and vaccine uptake were completed by 1,306 women through online survey platform. HPV knowledge was assessed using a 12-item question stem that covered the hazards of HPV infection, HPV vaccine dosage, benefits, and protection. Cluster analysis by combining monthly household income, educational level, and employment status was used to identify socioeconomic status (SES) class. The concentration index (CI) was employed as a measure of socioeconomic inequalities in HPV-related knowledge and vaccination. Linear regression and logistic regression were established to decompose the contributions of associated factors to the observed inequalities. Results: The CI for HPV-related knowledge and vaccine uptake was 0.0442 and 0.1485, respectively, indicating the higher knowledge and vaccination rate were concentrated in groups with high SES. Education and household income made the largest contribution to these inequalities. Age, residency and cervical cancer screening were also important contributors of observed inequalities. Conclusion: Socioeconomic inequalities in HPV-related knowledge and vaccination uptake are evident in China. Interventions to diffuse HPV-related information for disadvantaged groups are helpful to reduce these inequalities. Providing low or no-cost HPV vaccination and ensuring accessibility of vaccines in rural areas are also considered to be beneficial.

RESUMO

Breast cancer risk factors include lifestyle, genetic-hormonal influences, and viral infections. Human papillomavirus (HPV), known primarily as the etiological agent of cervical cancer, also appears active in breast carcinogenesis, as evidenced in our study of 56 patients from northeastern Brazil. We assessed the clinical and sociodemographic characteristics, correlating them with various breast cancer tumor types. HPV detection involved amplifying the L1 region, with viral load measured using the E2/E6 ratio and viral activity indicated by E5 oncogene expression. Predominantly, patients over 56 years of age with healthy lifestyles showed a high incidence of invasive ductal carcinoma and triple-negative breast cancer. HPV was detected in 35.7% of cases, mostly HPV16, which is associated with high viral loads (80 copies per cell) and significant E5 expression. These results hint at a possible link between HPV and breast carcinogenesis, necessitating further studies to explore this association and the underlying viral mechanisms.

RESUMO

OBJECTIVE: To evaluate the diagnostic accuracy of Electrical Impedance Spectroscopy (EIS)-assisted colposcopy in detecting CIN2+ Greek women towards standalone colposcopy, HPV mRNA testing, and p16/Ki67 immunostaining. METHODS: We conducted a cross-sectional observational study at the Cervical Pathology Clinic of the 2nd Obstetrics-Gynecology University Department of Hippokration Hospital Thessaloniki involving 316 patients from January 2022 to August 2023. All participants provided liquid-based cervical samples for cytology, HPV mRNA testing, and p16/Ki67 immunostaining. MAIN OUTCOME MEASURES: Subsequently, participants underwent both standalone colposcopy and EIS/ZedScan-assisted colposcopy, followed by cervical punch biopsies. RESULTS: The incorporation of EIS significantly enhanced the sensitivity of colposcopy, increasing it from 54.17% to 100%, equivalent to that of HPV mRNA testing and p16/Ki67 immunostaining, while achieving a high specificity (95.45%). The specificities observed with EIS/ZedScan-assisted and standalone colposcopy were notably superior to those of HPV-related biomarkers (HPV mRNA test and p16/Ki67 immunostaining). When compared to standalone colposcopy, HPV mRNA testing, and p16/Ki67 immunostaining, EIS/ZedScan-assisted colposcopy demonstrated the most favorable combination of Positive and Negative Predictive Values, at 90.57% and 100%, respectively. The inclusion of EIS/ZedScan in colposcopy led to the detection of 44 additional cases of true CIN2+ (100% of the total CIN2+ confirmed histologically) that were missed by standalone colposcopy. This discovery suggests a 45.83% increase in the detection of CIN2+ cases. CONCLUSIONS: The integration of EIS with colposcopy has demonstrated effectiveness in detecting cervical lesions, resulting in a significant detection increase of CIN2+ cases while offering optimal levels of sensitivity, specificity, and predictive values for CIN2+ detection.

RESUMO

Head and neck cancer (HNC) represents a significant global health challenge, with squamous cell carcinomas (SCCs) accounting for approximately 90% of all HNC cases. These malignancies, collectively referred to as head and neck squamous cell carcinoma (HNSCC), originate from the mucosal epithelium lining the larynx, pharynx, and oral cavity. The primary risk factors associated with HNSCC in economically disadvantaged nations have been chronic alcohol consumption and tobacco use. However, in more affluent countries, the landscape of HNSCC has shifted with the identification of human papillomavirus (HPV) infection, particularly HPV-16, as a major risk factor, especially among nonsmokers. Understanding the evolving risk factors and the distinct biological behaviors of HPV-positive and HPV-negative HNSCC is critical for developing targeted treatment strategies and improving patient outcomes in this complex and diverse group of cancers. Accurate diagnosis of HPV-positive HNSCC is essential for developing a comprehensive model that integrates the molecular characteristics, immune microenvironment, and clinical outcomes. The aim of this comprehensive review was to summarize the current knowledge and advances in the identification of DNA, RNA, and protein biomarkers in bodily fluids and tissues that have introduced new possibilities for minimally or non-invasive cancer diagnosis, monitoring, and assessment of therapeutic responses.

RESUMO

Cervical cancer remains a significant public health issue, particularly in regions with low screening uptake. This study evaluates the effectiveness of self-sampling and the 7-type HPV mRNA E6/E7 test in improving cervical cancer screening outcomes among a referral population in Mexico. A cohort of 418 Mexican women aged 25 to 65, referred for colposcopy and biopsy due to abnormal cytology results (ASC-US+), participated in this study. Self-samples were analyzed using both the 14-type HPV DNA test and the 7-type HPV mRNA E6/E7 test. The study assessed the sensitivity, specificity, positive predictive value (PPV), and the necessity of colposcopies to detect CIN3+ lesions. Participant acceptability of self-sampling was also evaluated through a questionnaire. The 7-type HPV mRNA E6/E7 test demonstrated equivalent sensitivity but significantly higher specificity (77.0%) and PPV for CIN3+ detection compared to the 14-type HPV DNA test (specificity: 45.8%, p < 0.001). The use of the HPV mRNA test as a triage tool reduced the number of colposcopies needed per CIN3+ case detected from 16.6 to 7.6 (p < 0.001). Self-sampling was highly accepted among participants, with the majority reporting confidence in performing the procedure, minimal discomfort, and willingness to undertake self-sampling at home. Self-sampling combined with the 7-type HPV mRNA E6/E7 testing offers a promising strategy to enhance cervical cancer screening by improving accessibility and ensuring precise diagnostics. Implementing these app roaches could lead to a significant reduction in cervical cancer morbidity and mortality, especially in underserved populations. Future research should focus on the long-term impact of integrating these methods into national screening programs and explore the cost-effectiveness of widespread implementation.

RESUMO

Cervical cancer is a major cause of morbidity and mortality globally with a disproportionate impact on women in low- and middle-income countries. In 2021, the World Health Organization (WHO) called for increased vaccination, screening, and treatment to eliminate cervical cancer. However, even with widespread rollout of human papillomavirus (HPV) prophylactic vaccines, millions of women who previously acquired HPV infections will remain at risk for progression to cancer for decades to come. The development and licensing of an affordable, accessible therapeutic HPV vaccine, designed to clear or control carcinogenic HPV and/or to induce regression precancer could significantly contribute to the elimination efforts, particularly benefiting those who missed out on the prophylactic vaccine. One barrier to development of such vaccines is clarity around the regulatory pathway for licensure. In Washington, D.C. on September 12-13, 2023, a meeting was convened to provide input and guidance on trial design with associated ethical and regulatory considerations. This report summarizes the discussion and conclusions from the meeting. Expert presentation topics included the current state of research, potential regulatory challenges, WHO preferred product characteristics, modeling results of impact of vaccine implementation, epidemiology and natural history of HPV infection, immune responses related to viral clearance and/or precancer regression including potential biomarkers, and ethical considerations. Panel discussions were held to explore specific trial design recommendations to support the licensure process for two vaccine indications: (1) treatment of prevalent HPV infection or (2) treatment of cervical precancers. Discussion covered inclusion/exclusion criteria, study endpoints, sample size and power, safety, study length, and additional data needed, which are reported here. Further research of HPV natural history is needed to address identified gaps in regulatory guidance, especially for therapeutic vaccines intended to treat existing HPV infections.
