RESUMO

BACKGROUND: Human papillomavirus (HPV) causes several cancers such as cervical cancer and some head and neck (oral cavity, pharynx, and larynx), vulval, vaginal, anal, and penile cancers. As HPV vaccination is available, there is potential to prevent these cancers attributed to HPV and consequently the burden associated with them. The aim of this analysis was to estimate the number of HPV-related cancer deaths and the productivity costs due to years of life lost (YLL) in the United Kingdom (UK). METHOD: A model was developed utilizing UK 2019 mortality data sourced from country-specific databases for England, Scotland, Wales, and Northern Ireland for the following HPV-related cancers: head and neck (ICD-10 C00-14 and C32), cervix uteri (C53), vaginal (C51), vulval (C52), anal (C21), and penile (C60). The proportion of deaths and years of life lost (YLL) due to HPV were estimated using HPV attributable fractions for each anatomic location from the published literature. Labor force participation, retirement ages, and mean annual earnings, discounted at 3.5% annually, were applied to YLL to calculate the present value of future lost productivity (PVFLP). RESULTS: A total of 1817 deaths due to HPV-related cancers were reported in the UK in 2019 resulting in 31,804 YLL. Restricting to only YLL that occurred prior to retirement age yielded a total YPLL of 11,765 and a total PVFLP of £187,764,978. CONCLUSIONS: There is a high disease burden in the UK for HPV-related cancers, with a large economic impact on the wider economy due to productivity losses. Implementing and reinforcing public health measures to maintain high HPV vaccination coverage in both males and females may further facilitate reduction of this burden.

RESUMO

BACKGROUND: Human papilloma virus (HPV) is a common cause of several types of cancer, including head and neck (oral cavity, pharynx, oropharynx, hypopharynx, nasopharynx, and larynx), cervical, vulval, vaginal, anal, and penile cancers. As HPV vaccines are available, there is potential to prevent HPV-related disease burden and related costs. METHOD: A model was developed for nine Central Eastern European (CEE) countries (Bulgaria, Croatia, Czechia, Hungary, Poland, Romania, Serbia, Slovakia, Slovenia). This model considered cancer patients who died from 11 HPV-related cancers (oropharynx, oral cavity, nasopharynx, hypopharynx, pharynx, anal, larynx, vulval, vaginal, cervical, and penile) in 2019. Due to data limitations, Bulgaria only included four cancer types. The model estimated the number of HPV-related deaths and years of life lost (YLL) based on published HPV-attributable fractions. YLL was adjusted with labor force participation, retirement age and then multiplied by mean annual earnings, discounted at a 3% annual rate to calculate the present value of future lost productivity (PVFLP). RESULTS: In 2019, there were 6,832 deaths attributable to HPV cancers resulting in 107,846 YLL in the nine CEE countries. PVFLP related to HPV cancers was estimated to be €46 M in Romania, €37 M in Poland, €19 M in Hungary, €15 M in Czechia, €12 M in Croatia, €10 M in Serbia, €9 M in Slovakia, €7 M in Bulgaria and €4 M in Slovenia. CONCLUSIONS: There is a high disease burden of HPV-related cancer-related deaths in the CEE region, with a large economic impact to society due to substantial productivity losses. It is critical to implement and reinforce public health measures with the aim to reduce the incidence of HPV-related diseases, and the subsequent premature cancer deaths. Improving HPV screening and increasing vaccination programs, in both male and female populations, could help reduce this burden.

RESUMO

BACKGROUND: Human papillomavirus (HPV) is a common sexually transmitted infection and the leading cause of cervical cancer. The HPV vaccine is a safe and effective way to prevent HPV infection. In Zambia, the vaccine is given during Child Health Week to girls aged 14 years who are in and out of school in two doses over two years. The focus of this evaluation was to establish the cost to administer a single dose of the vaccine as well as for full immunisation of two doses. METHODS: This work was part of a broader study on assessing HPV programme implementation in Zambia. For HPV costing aspect of the study, with a healthcare provider perspective and reference year of 2020, both top-down and micro-costing approaches were used for financial costing, depending on the cost data source, and economic costs were gathered as secondary data from Expanded Programme for Immunisation Costing and Financing Project (EPIC), except human resource costs which were gathered as primary data using existing Ministry of Health salary scales and reported time spent by different health cadres on activities related to HPV vaccination. Data was collected from eight districts in four provinces, mainly using a structured questionnaire, document reviews and key informant interviews with staff at national, provincial, district and health facility levels. Administrative coverage rates were obtained for each district. RESULTS: Findings show that schools made up 53.3% of vaccination sites, community outreach sites 30.9% and finally health facilities 15.8%. In terms of coverage for 2020, for the eight districts sampled, schools had the highest coverage at 96.0%. Community outreach sites were at 6.0% of the coverage and health facilities accounted for only 1.0% of the coverage. School based delivery had the lowest economic cost at USD13.2 per dose and USD 28.1 per fully immunised child (FIC). Overall financial costs for school based delivery were US$6.0 per dose and US$12.4 per FIC. Overall economic costs taking all delivery models into account were US$23.0 per dose and US$47.6 per FIC. The main financial cost drivers were microplanning, supplies, service delivery/outreach and vaccine co-financing; while the main economic cost drivers were human resources, building overhead and vehicles. Nurses, environmental health technicians and community-based volunteers spent the most time on HPV related vaccination activities compared to other cadres and represented the greatest human resource costs. CONCLUSIONS: The financial cost of HPV vaccination in Zambia aligns favourably with similar studies conducted in other countries. However, the economic costs appear significantly higher than those observed in most international studies. This discrepancy underscores the substantial strain placed on healthcare resources by the program, a burden that often remains obscured. While the vaccine costs are currently subsidized through the generous support of Gavi, the Vaccine Alliance, it's crucial to recognize that these expenses pose a considerable threat to long-term sustainability. Consequently, countries such as Zambia must proactively devise strategies to address this challenge.

RESUMO

BACKGROUND/AIM: The global impact of the COVID-19 pandemic resulted in disruptions to healthcare systems throughout the world. The numbers of cytology examinations, human papillomavirus (HPV) tests, and women referred for colposcopy decreased in many countries. There have been no reports on cervical cancer screening in Germany. This study aimed to describe changes in the numbers of colposcopies, cytology examinations, HPV tests, and histological results during the pandemic compared to the pre-pandemic years in order to evaluate the impact of the COVID-19 pandemic on cervical cancer screening. PATIENTS AND METHODS: The numbers of colposcopies, cytology examinations, HPV tests, and histologic results were analyzed retrospectively for the period January 2018 to December 2022. The 2 years period before the pandemic (2018 and 2019) were compared with the 3 years period of the pandemic (2020-2022). RESULTS: In total, 6,518 colposcopies were performed in 5,579 women. The numbers of colposcopies, cytology examinations, and high-risk HPV (hrHPV) tests increased during the pandemic years. The number of biopsies per year taken was stable (range=450-554). The relative numbers of cervical intraepithelial neoplasia (CIN) III/HSIL findings were stable, while the numbers of cervical cancers identified increased slightly from 15 (6.6%) in 2018 to 22 (7.4%) in 2022. CONCLUSION: Increases in numbers of women examined and colposcopies were observed in the years 2021 and 2022 during the pandemic, in comparison to the preceding years. These also led to increases in the figures for cytology, hrHPV, histology, and operations. The onset of the pandemic occurred in the same year as a newly organized screening program started in Germany. The increases might therefore be due to the newly organized screening system.

RESUMO

BACKGROUND: Incidence of anal squamous cell carcinoma is increasing, but vaccination against human papillomavirus (HPV) and removal of precancerous anal lesions could prevent new cases. The overall HPV-associated cancer incidence is reported to be higher in rural populations and in counties with lower economic status. We assessed these differences specifically for HPV-associated anal squamous cell carcinoma and described the geographic, county-level economic, and sociodemographic variations in incidence rates and trends. METHODS: We analyzed data from the US Cancer Statistics to assess age-standardized incidence rates of HPV-associated squamous cell carcinomas among adults aged 18 years and older from 2001 to 2019. We calculated rate ratios and 95% confidence intervals to examine differences in incidence rates. We also quantified changes in incidence rates over time using joinpoint regression. RESULTS: From 2001 to 2019, 72 421 new cases of HPV-associated anal squamous cell carcinoma were diagnosed among women (2.8 per 100 000) and 37 147 among men (1.7 per 100 000). Age-standardized incidence rates were higher in the South compared with other census regions and in counties ranked in the bottom 25% and 25%-75% economically than in the top 25%. The overall incidence rate increased in women but remained stable in men during 2009-2019. Incidence rates increased in adults aged 50 years and older but decreased among those aged 40-44 years from 2001 to 2019 in women and from 2007 to 2019 in men. CONCLUSIONS: There were inequities in HPV-associated anal squamous cell carcinoma incidence by geographic and county-level economic characteristics. Failure to improve vaccine and treatment equity may widen existing disparities.

RESUMO

OBJECTIVES: There is an unmet need for therapeutically relevant biomarkers for advanced penile squamous cell carcinoma (pSCC). Proposed immunohistochemistry (IHC)-based biomarkers include programmed death-ligand 1 (PD-L1), trophoblast cell-surface antigen 2 (TROP2), and nectin-4; however, there is a paucity of data pertaining to these biomarkers. Herein, we investigated the expression of PD-L1, TROP2, and nectin-4 in a well-annotated cohort of pSCCs. METHODS: A single-institution pathology archive was queried for patients who had a partial or total penectomy for pSCC between January 2000 and December 2022. Whole-slide sections were stained with antibodies against PD-L1 (22C3), TROP2, and nectin-4. Expression in tumor cells was quantified using H-scores (0-300). Associations between IHC expression, human papilloma virus (HPV) status, clinicopathologic findings, and outcome parameters were evaluated. RESULTS: This study included 121 patients. For PD-L1, the median combined positive and H-scores were 1 and 0, respectively; 32.7 % of the cases had an H-score>0. Compared to PD-L1-negative tumors, PD-L1-positive tumors had higher pT stage and grade. The median TROP2 and nectin-4 H-scores were 230 and 140, respectively, with high TROP2 and nectin-4, defined by an H-score>200, noted in 80.7 % and 10.9 % of cases, respectively. High-risk HPV-positive cases had higher TROP2 and nectin-4 scores compared to HPV-negative cases. Patients with high TROP2 expression had significantly more disease progression, and patients with high nectin-4 expression had significantly fewer deaths due to disease. CONCLUSIONS: High expression of TROP2 and nectin-4 in pSCC support evaluation of these markers as therapeutic targets pending validation of our findings.

RESUMO

COVID-19 disrupted school attendance in many countries, delaying routine adolescent vaccination against human papillomavirus (HPV) in some settings. We used Policy1-Cervix, a dynamic model simulating HPV transmission, natural history, vaccination, cervical screening, and diagnosis of HPV-related cancers, to estimate the impact on HPV-related cancers from disruptions to HPV vaccination in a high-income setting. A baseline scenario of no disruption to HPV vaccination was modelled, which assumed uptake of the nonavalent vaccine at the age of 12 by 82.4% of females and 75.5% of males, as is the coverage in Australia. Additional lifetime HPV-related cancer cases were calculated for three disruption scenarios affecting one birth cohort (2008; aged 12 in 2020) compared to the baseline scenario: (1) 1-year delay (no doses missed); (2) 1- to 7-year delay (slow catch-up); (3) no catch-up (herd effects only). A fourth scenario assumed no catch-up HPV vaccination for two birth cohorts, that is all individuals born in 2008 and in 2009 missed vaccination (worst-case scenario). Compared to 1532 HPV-related cancer cases estimated for the baseline no disruption scenario, we found a 1-year delay could result in ≤0.3% more HPV-related cancers (n = 4) but the increase would be greater if catch-up was slower (5%; n = 70), and especially if there was no catch-up (49%; n = 750). Additional cancers for a single missed cohort were most commonly cervical (23% of the additional cases) and anal cancers (16%) in females and oropharyngeal cancers in males (20%). In the worst-case scenario of two birth cohorts missing vaccination, ≤62% more HPV-related cancers would be diagnosed (n = 1892). In conclusion, providing catch-up of missed HPV vaccines is conducted, short-term delays in vaccinating adolescents are unlikely to have substantial long-term effects on cancer.

RESUMO

Cervical cancer is the fourth most common cancer in women, with a high disease burden worldwide. Human papillomavirus (HPV) vaccination reduces HPV-related infection and associated cervical lesions and cancers. Few studies have explored HPV vaccination impact in real-world settings in China. This study aims to monitor HPV vaccine uptake and its effects on HPV-related diseases, evaluating vaccine effectiveness in a real-world context and complementing clinical trial results. Electronic health records (EHRs) from 2010 to 2020 from the Yinzhou Regional Health Information Platform (YRHIP) will be queried/extracted to identify and monitor HPV vaccine uptake in females aged 9-45 years, and HPV-related screening and prevalence (i.e., cervical HPV infection, cervical intraepithelial neoplasia [CIN] grades 1-3, and cervical cancer) in a cohort of females aged 9-70 years. Cervical cancer screening guidelines and expert consultation will be used for intra-database validation, to determine the best algorithm for identifying HPV-related disease. Pre-launch (2010-2016) and post-launch (2018-2020) periods are predefined. A time trend analysis will be performed to describe the vaccination impact on disease prevalence and, if prerequisite conditions are met, vaccine effectiveness will be computed using logistic regression, adjusting for age, calendar year, history of screening and HPV infection. Cohort study design, outcomes validation, data linkage, and multi-step statistical analyses could provide valuable experience for designing other real-world studies in the future. The study outcomes can help inform policy-makers about uptake and HPV vaccination policy in girls and women in Yinzhou District, and provide insights on progress toward achieving goals set by the World Health Organization.

RESUMO

The high prevalence of human papillomavirus (HPV) infection in China suggests there would be a substantial positive health impact of widespread vaccination against HPV. We adapted a previously described dynamic transmission model of the natural history of HPV infection and related diseases to the Chinese setting to estimate the public health impact in China of 2-valent (with and without cross-protection), 4-valent, and 9-valent HPV vaccination strategies. The model predicted the incidence and mortality associated with HPV-related diseases, including cervical and noncervical cancers, genital warts, and recurrent respiratory papillomatosis (RRP), based on the various vaccination coverage rate (VCR) scenarios, over a 100-year time horizon. The public health impact of the 4 vaccination strategies was estimated in terms of cases and deaths averted compared to a scenario with no vaccination. Under the assumption of various primary and catch-up VCR scenarios, all 4 vaccination strategies reduced the incidence of cervical cancer in females and noncervical cancers in both sexes, and the 4-valent and 9-valent vaccines reduced the incidence of genital warts and RRP in both sexes. The 9-valent vaccination strategy was superior on all outcomes. The number of cervical cancer cases averted over 100 years ranged from ~ 1 million to ~ 5 million while the number of cervical cancer deaths averted was ~ 345,000 to ~ 1.9 million cases, depending on the VCR scenario. The VCR for primary vaccination was the major driver of cases averted.

RESUMO

OBJECTIVE: To evaluate the risk for cervical intraepithelial neoplasia grade 3 (CIN 3) or worse (including adenocarcinoma in situ [AIS] and invasive cervical cancer) associated with non-16/18 human papillomavirus (HPV) types (other HPV) among women with atypical glandular cells (AGC) in cervical cytology. METHODS: This population-based cohort study evaluates the risk of CIN 3 or worse associated with other HPV types. Human papillomavirus genotyping was performed on Pap tests collected in Sweden from 341 women with AGC that were positive for other HPV types from February 17, 2014, to December 31, 2018. The women were followed for histopathologic outcomes using comprehensive registry linkages until December 31, 2019. Cumulative incidence proportions of CIN 3 or worse by specific HPV type were calculated using 1-minus Kaplan-Meier function. Hazard ratios (HRs) for CIN 3 or worse were generated using multivariate Cox regression. RESULTS: Of 341 women, 134 (39.3%) had CIN 3-AIS, but there were only five (1.5%) women in the cohort with invasive cervical cancer. Human papillomavirus 45 preceded 80.0% of invasive cervical cancer cases. Among women positive for HPV33, 82.9% (95% CI 58.0-97.3%) had CIN 3 or worse during follow-up. Positivity for HPV31 conferred the highest HR for CIN 3 or worse relative to other types, both in primary cytology and primary HPV screening (HR 2.71, 95% CI 1.47-5.00 and HR 3.41, 95% CI 1.95-5.96, respectively). CONCLUSION: Among non-16/18 HPV types in AGC, HPV31 and 33 had the highest risk for CIN 3 or worse, whereas most of the women with invasive cancer were positive for HPV45. Extended HPV genotyping may be helpful for the management of AGC.

RESUMO

Previous studies reported human immunodeficiency virus (HIV) could enhance human papillomavirus (HPV)-induced cervical cancer. Therefore, the burden of cervical cancer associated with HIV across different regions and time periods need to be assessed. We aim to investigate the global burden of cervical cancer associated with HIV infection. Age standardized rates (ASRs) of cervical cancer disability-adjusted life-years (DALYs) in females (≥15 years old) were calculated by standardization, according the age-specific DALYs numbers extracted from GBD data set 2019. Population attributable fractions was calculated by combining the published risk ratio, with the HIV prevalence (≥15 years old) from Joint United Nations Programme on HIV and AIDS (UNAIDS), and transferred to estimate the HIV-associated cervical cancer burden. Expected annual percentage changes (EAPCs) was calculated to describe the temporal trend of ASR from 1990 to 2019. Pearson correlation analysis were conducted to assess the correlation between the ASR or EAPCs and the socio-demographic index. The worldwide DALYs ASR caused by HIV-associated cervical cancer rose from 3.78 (95% confidence interval [CI]: 2.19-5.56) in 1990 to 9.50 (95% CI: 5.66-13.79) in 2019 per 100k population. In 2019, the region with the greatest burden was Eastern and Southern Africa, with the highest DALYs of 273 900 (95% CI: 149 100-476 400) and ASR of 254.44 per 100k population (95% CI: 168.86-329.28). Notably, the Eastern Europe and Central Asia regions had the highest EAPC (14.07%) of HIV-associated DALYs ASR. Women in Eastern and Southern Africa experience the greatest burden of HIV-associated cervical cancer, while the Eastern Europe and Central Asia regions had witnessed the largest increase over the last 30 years. Prioritize the promotion of HPV vaccination and cervical cancer screening for women living with HIV were crucial in these regions.

RESUMO

OBJECTIVE: To compare the costs and effects of three sampling strategies for human papillomavirus (HPV) primary screening. DESIGN: Cost-consequence analysis from a health system perspective using a deterministic decision tree model. SETTING: England. PARTICIPANTS: A cohort of 10 000 women aged 25-65 years eligible for the National Health Service Cervical Screening Programme (NHSCSP). METHODS: The model was based on the NHSCSP HPV primary screening pathway and adapted for self-sampling. It used a 3-year cycle: routine screening (year 1) and recall screening (years 2/3). Parameter inputs were informed using published studies, NHSCSP reports and input from experts and manufacturers. Costs were from 2020/2021, British pound sterling (£). INTERVENTIONS: Three sampling strategies were implemented: (1) routine clinician-collected cervical sample, (2) self-collected first-void (FV) urine, (3) self-collected vaginal swab. The hypothetical self-sampling strategies involved mailing women a sampling kit. MAIN OUTCOME MEASURES: Primary outcomes: overall costs (for all screening steps to colposcopy), number of complete screens and cost per complete screen. SECONDARY OUTCOMES: number of women screened, number of women lost to follow-up, cost per colposcopy and total screening costs for a plausible range of uptake scenarios. RESULTS: In the base case, the average cost per complete screen was £56.81 for clinician-collected cervical sampling, £38.57 for FV urine self-sampling and £40.37 for vaginal self-sampling. In deterministic sensitivity analysis, the variables most affecting the average cost per screen were the cost of sample collection for clinician-collected sampling and the cost of laboratory HPV testing for the self-sampling strategies. Scaled to consider routine screening in England, if uptake in non-attenders increased by 15% and 50% of current screeners converted to self-sampling, the NHSCSP would save £19.2 million (FV urine) or £16.5 million (vaginal) per year. CONCLUSION: Self-sampling could provide a less costly alternative to clinician-collected sampling for routine HPV primary screening and offers opportunities to expand the reach of cervical screening to under-screened women.

RESUMO

This review presents the epidemiology, pathophysiology, prevention, and management of sexually transmitted human papillomavirus (HPV) and its associated diseases. HPV is the most common sexually transmitted infection worldwide. Prevalence varies regionally. Low-risk strains cause anogenital warts, which can be managed with patient- or provider-applied therapies. High-risk strains cause lower anogenital cancers. Primary and secondary prevention strategies include vaccination and screening for precancerous lesions, respectively. Management of abnormal screening results vary by test result, anatomic site, and individual cancer risk. Approaches include close rescreening, high-resolution visualization with biopsy, and-when biopsy-proven precancer is identified-removal or destruction of the lesion.

RESUMO

OBJECTIVES: We aim to propose a modified surveillance strategy using a novel blood assay that detects plasma circulating tumor-specific HPV DNA with reported 100% NPV and 94% PPV as the main method of detection to understand the cost implications of potentially avoiding routine imaging and surveillance visits at our institution. METHODS: We performed a retrospective chart review focusing on recurrences in p16+ patients with OPSCC and defined two surveillance strategies: "Strategy A", follow-up visits with flexible laryngoscopy (FL) plus regular imaging studies; "Strategy B", follow-up visits with FL plus regular NavDx assays and imaging used at the discretion of the physician(s) in cases of high clinical suspicion. RESULTS: Of the p16+ OPSCC patients (n = 214), 23 had confirmed recurrence (11%). Standard work-flow model determined 72 imaging studies and 2198 physical examinations with FL were needed to detect one recurrence. Potential individual patient cost reduction during surveillance was 42%. CONCLUSION: Implementing NavDx for HPV + OPSCC surveillance would benefit patients by reducing costs and unnecessary diagnostic testing.

RESUMO

The annual direct medical cost attributable to human papillomavirus (HPV) in the United States over the period 2004-2007 was estimated at $9.36 billion in 2012 (updated to 2020 dollars). The purpose of this report was to update that estimate to account for the impact of HPV vaccination on HPV-attributable disease, reductions in the frequency of cervical cancer screening, and new data on the cost per case of treating HPV-attributable cancers. Based primarily on data from the literature, we estimated the annual direct medical cost burden as the sum of the costs of cervical cancer screening and follow-up and the cost of treating HPV-attributable cancers, anogenital warts, and recurrent respiratory papillomatosis (RRP). We estimated the total direct medical cost of HPV to be $9.01 billion annually over the period 2014-2018 (2020 U.S. dollars). Of this total cost, 55.0% was for routine cervical cancer screening and follow-up, 43.8% was for treatment of HPV-attributable cancer, and less than 2% was for treating anogenital warts and RRP. Although our updated estimate of the direct medical cost of HPV is slightly lower than the previous estimate, it would have been substantially lower had we not incorporated more recent, higher cancer treatment costs.

RESUMO

Importance: Human papillomavirus vaccination coverage rates lie below desired thresholds in Switzerland. Because general practitioners are the main contact for the relatively rare health issues of many Swiss young adults, primary care offers an important opportunity to provide catch-up human papillomavirus vaccination. Objective: To examine the knowledge, experiences, and attitudes of Swiss university students in the context of receiving human papillomavirus vaccination during primary care visits. Design, Setting, and Participants: This self-administered, cross-sectional, web-based survey study was conducted among students of 3 universities and 1 educational institution for health professions in the Swiss Canton of Zurich. Specific questions about human papillomavirus vaccination experience were directed to respondents who had received at least 1 dose administered by a general practitioner. Responses were collected during 12-week intervals between November 11, 2020, and April 7, 2021, and data were analyzed from August 3 to August 30, 2022. Main Outcomes and Measures: The primary outcome was whether human papillomavirus vaccination had been administered on the patient's or the general practitioner's initiative. Results: The responses of 5524 participants (median [IQR] age, 23 [21-25] years; 3878 women [70.2%]) were analyzed. The survey completion rate was 90.9% (5524 of 6076 students who consented to participate). A total of 2029 respondents (1792 women [46.2%] and 237 men [14.6%]) reported having received at least 1 human papillomavirus vaccination dose, of whom 740 (36.5%) had received at least 1 dose administered by a general practitioner. Among these, 190 respondents (25.7%) reported that vaccine administration had occurred on their request rather than on their general practitioner's initiative. Among all respondents, 4778 (86.5%) wanted to obtain more information about human papillomavirus vaccination at a general practitioner's office, and 2569 (55.3%) rated acute consultations in general practice as inappropriate for addressing human papillomavirus vaccination. Conclusions and Relevance: The findings of this survey study of Swiss university students suggest that primary care shows a high potential for increasing human papillomavirus vaccination coverage rates in Switzerland. However, there was room for improvement in the proactivity of general practitioners, especially with men, and in the attitudes of students toward the appropriateness of acute consultations in general practice for addressing human papillomavirus vaccination.

RESUMO

BACKGROUND: Cervical cancer is a major concern to women's health, being the fourth most common cancer worldwide. A great percentage of these cancer is consequence of an HPV infection, namely from specific genotypes such as 16/18. Portuguese screening program subjects women to a reflex cytology triage every 5 years. Aptima® HPV is a screening test which presents better specificity than other tests which are used in Portugal (Hybrid Capture® 2 and Cobas® 4800) and still have a comparable sensitivity. The present study aims to estimate the number of diagnostic tests and costs that are avoided using Aptima® HPV compared to the use of two other tests, Hybrid Capture® 2 and Cobas® 4800, within the cervical cancer screening programme in Portugal. METHODS: A model, consisting of a decision-tree, was developed to represent the full Portuguese screening program for cervical cancer. This model is used to compare the costs resulting from using Aptima® HPV test versus the other tests used in Portugal, during 2 years. Other outcomes such as the number of additional tests and exams were also computed. This comparison considers the performance of each test (sensitivity and specificity) and assumes an equal price for every test compared. RESULTS: Cost savings resulting from the use of Aptima® HPV are estimated at approximately €382 million versus Hybrid Capture® 2 and €2.8 million versus Cobas® 4800. Moreover, Aptima® HPV prevents 265,443 and 269,856 additional tests and exams when compared with Hybrid Capture® 2 and Cobas® 4800. CONCLUSIONS: The use of Aptima® HPV resulted in lower costs as well as less additional test and exams. These values result from the greater specificity of Aptima® HPV, which signals less false positive cases and consequently avoids carrying out additional tests.

RESUMO

BACKGROUND: Cervical cancer is one of the most common cancers in women, the cause of which is mostly human papilloma virus (HPV). The aim of this study was to determine the economic burden of cervical cancer and premalignant lesions associated with HPV infection from a societal perspective. METHODS: The study is a partial economic evaluation (cost of illness), which was conducted cross-sectionally in the referral university clinic in Fars province in 2021. The prevalence-based and bottom-up approaches used to calculate the costs, the indirect costs were calculated by human capital approach. RESULTS: The mean cost of premalignant lesions associated with HPV infection was USD 2,853 per patient, which 68.57% was direct medical costs. In addition, the mean cost of cervical cancer was USD 39,327 per patient, the largest share of which (57.9%) was related to indirect costs. The mean annual cost of cervical cancer patients in the country was estimated at USD 40,884,609 as well. CONCLUSION: Cervical cancer and premalignant lesions associated with HPV infection imposed a significant economic burden on the health system and patients. The results of the present study can help health policymakers with efficient and equitable prioritization and allocation of resources.
