Fuady A, Setiawan D, Man I, de Kok IMCM, Baussano I. Toward a Framework to Assess the Financial and Economic Burden of Cervical Cancer in Low- and Middle-Income Countries: A Systematic Review. JCO Glob Oncol 2024; 10:e2400066. [PMID: 39116362 DOI: 10.1200/go.24.00066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 05/02/2024] [Accepted: 06/11/2024] [Indexed: 08/10/2024] Open
Abstract
PURPOSE To review the economic burden assessment of cervical cancer in low- and middle-income countries (LMICs) and use the findings to develop a pragmatic, standardized framework for such assessment. METHODS We first systematically reviewed articles indexed in scientific databases reporting the methodology for collecting and calculating costs related to the cervical cancer burden in LMICs. Data on study design, costing approach, cost perspective, costing period, and cost type (direct medical costs [DMC], direct nonmedical costs [DNMC], and indirect costs [IC]) were extracted. Finally, we summarized the reported limitations in the methodology and used the solutions to inform our framework. RESULTS Cervical cancer treatment costs across LMICs vary greatly and can be extremely expensive, up to 70,968 International US dollars. Economic and financial assessment methods also vary greatly across countries. Of the 28 reviewed articles, 25 studies reported DMC for cervical cancer treatment by extracting cost information from billing or insurance databases (eight studies), conducting surveys (five), and estimating the costs (12). Only 11 studies-mainly through surveys-reported DNMC and IC. The economic burden assessment framework includes health care/payer and societal perspectives (DMC, DNMC, IC, and human capital loss) across the cervical cancer screening and treatment continuum. To assess health care/payer costs, we recommend combining the predefined treatment standards with actual local treatment practices, multiplied by unit costs. To assess societal costs, we recommend conducting a cost survey in line with a standardized yet adaptable protocol. CONCLUSION Our standardized, pragmatic framework allows assessment of economic and financial burden of cervical cancer in LMICs despite the different levels of available resources across countries. This framework will facilitate global comparisons and monitoring and may also be applied to other cancers.

Abstract
OBJECTIVE To assess the costs and benefits of two algorithms for cervical cancer screening in Belgium (1) high-risk human papillomavirus (HR-HPV) primary screening and (2) HR-HPV and liquid-based cytology (LBC) co-testing. METHODS A decision tree was adapted from published work and parameterised using HORIZON study data and Belgian cost and population data. The theoretical model represents two different screening algorithms for a cohort of 577 846 women aged 25-64 attending routine cervical screening. Scenario analyses were used to explore the impact of including vaccinated women and alternative pricing approaches. Uncertainty analyses were conducted. RESULTS The cost per woman screened was €113.50 for HR-HPV primary screening and €101.70 for co-testing, representing a total cost of €65 588 573 and €58 775 083, respectively, for the cohort; a 10% difference. For one screening cycle, compared to HR-HPV primary, co-testing resulted in 13 173 more colposcopies, 67 731 more HR-HPV tests and 477 020 more LBC tests. Co-testing identified 2351 more CIN2+ cases per year (27% more than HR-HPV primary) and 1602 more CIN3+ cases (24% more than HR-HPV primary) than HR-HPV primary. CONCLUSION In Belgium, a co-testing algorithm could increase cervical pre-cancer detection rates compared to HR-HPV primary. Co-testing would cost less than HR-HPV primary if the cost of the HPV test and LBC were cost-neutral compared to the current cost of LBC screening but would cost more if the cost per HPV test and LBC were the same in both co-testing and HR-HPV primary strategies.

Abstract
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.

Abstract
Bulgaria is among the European Union (EU) countries with the highest burden of cervical cancers and life expectancy below the EU average. The majority of cervical cancer cases (more than 95%) are caused by the human papillomavirus (HPV). The aim of this retrospective, cost of illness study is to identify direct healthcare costs of cervical cancer in Bulgaria from the payer perspective and to calculate indirect costs and the associated years of life lost. Costs data were sourced from the National Health Insurance Fund from January 2018 to December 2020. Years of life lost were calculated based on the country and gender-specific life expectancy. Indirect costs due to productivity loss were calculated using the human capital approach. The total treatment costs for 3540 patients with cervical cancer are EUR 5,743,657 (2018), EUR 6,377,508 (2019), and EUR 6,751,182 (2020). The costs associated with drug acquisition and administration accounted for the majority (63%) of total healthcare costs followed by hospital management costs (14%). An estimated total of 20,446 years of life were lost due to cervical cancer for the period 2018-2020. The costs of productivity losses are estimated at EUR 7,578,014. Our study showed that the economic burden of cervical cancer in Bulgaria is substantial. Focus on cervical cancer prevention via vaccination against the human papillomavirus, timely screening, early diagnosis, and higher vaccine coverage rates could reduce its economic burden in Bulgaria.

Lyme borreliosis in Belgium: a cost-of-illness analysis. BMC Public Health 2022; 22:2194. [PMID: 36443755 PMCID: PMC9703731 DOI: 10.1186/s12889-022-14380-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Accepted: 10/14/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Lyme borreliosis (LB) is the most common tick-borne disease in Europe and North America, yet its economic burden remains largely unknown. This study aimed to estimate the economic cost associated with the different clinical manifestations of LB in Belgium. METHODS An incidence approach and societal perspective were used to estimate the total cost-of-illness for LB in Belgium. Costs were calculated for patients with erythema migrans (EM) or disseminated/late LB, including patients who developed post-treatment Lyme disease syndrome (PTLDS). Direct medical, direct non-medical (transportation & paid help) and indirect non-medical costs (productivity losses) were included in the analysis. Ambulatory cost data were collected through a prospective cohort study from June 2016 to March 2020, in which patients with LB were followed up 6 to 12 months after diagnosis. Hospitalization costs were retrieved from the Minimal Clinical Data registry, a mandatory registry for all Belgian hospitals, linked to the Minimal Financial Data registry. Costs were expressed in 2019 euros. RESULTS The total annual cost associated with clinical manifestations of LB in Belgium was estimated at €5.59 million (95% UI 3.82-7.98). Of these, €3.44 million (95% UI 2.05-5.48) or 62% was related to disseminated/late LB diagnoses and €2.15 million (95% UI 1.30-3.26) to EM. In general, direct medical costs and productivity losses accounted for 49.8% and 46.4% of the total costs, respectively, while direct non-medical costs accounted for only 3.8%. The estimated mean costs were €193 per EM patient and €5,148 per disseminated/late LB patient. While patients with PTLDS seemed to have somewhat higher costs compared to patients without PTLDS, the number of patients was too small to have representative estimates. CONCLUSIONS We estimate the total annual direct medical costs, direct non-medical and indirect non-medical costs associated with LB to exceed €5.5 million per year, almost evenly distributed between EM (40%) and disseminated/late LB (60%). EM costs 26 times less per patient but occurs also 16 times more frequently than disseminated/late LB. The cost burden remains limited by comparison to other infectious diseases due to the relative lower incidence.

Health Impact and Cost-Effectiveness of Implementing Gender-Neutral Vaccination With the 9-Valent Human Papillomavirus Vaccine in Belgium. Front Pharmacol 2021; 12:628434. [PMID: 33912045 PMCID: PMC8072375 DOI: 10.3389/fphar.2021.628434] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 02/09/2021] [Indexed: 01/08/2023] Open
Abstract
Background: Routine human papillomavirus (HPV) immunization in Belgium is currently regionally managed, with school-aged girls receiving the 9-valent HPV (9vHPV) vaccine in Flanders and Wallonia-Brussels with a national catch-up program for females only. This study will assess whether expanding these programs to gender-neutral vaccination (GNV) with the 9vHPV vaccine is a cost-effective strategy in Belgium. Methods: A validated HPV-type transmission dynamic model estimated the potential health and economic impact of regional vaccination programs, comparing GNV versus female-only vaccination (FOV) with the 9vHPV vaccine in individuals aged 11-12 years in Flanders, GNV with the 9vHPV vaccine versus FOV with the 2-valent HPV (2vHPV) vaccine in individuals aged 12-13 years in Wallonia-Brussels, and national catch-up GNV versus FOV with the 9vHPV vaccine for those aged 12-18 years. Vaccination coverage rates of 90, 50, and 50% in both males and females were used in the base cases for the three programs, respectively, and sensitivity analyses were conducted. All costs are from the third-party payer perspective, and outcome measures were reported over a 100-year time horizon. Results: GNV with the 9vHPV vaccine was projected to decrease the cumulative incidence of HPV 6/11/16/18/31/33/45/52/58-related diseases relative to FOV in both Flanders and Wallonia-Brussels. Further reductions were also projected for catch-up GNV with the 9vHPV vaccine, including reductions of 6.8% (2,256 cases) for cervical cancer, 7.1% (386 cases) and 18.8% (2,784 cases) for head and neck cancer in females and males, respectively, and 30.3% (82,103 cases) and 44.6% (102,936 cases) for genital warts in females and males, respectively. As a result, a GNV strategy would lead to reductions in HPV-related deaths. Both regional and national catch-up GNV strategies were projected to reduce cumulative HPV-related disease costs and were estimated to be cost-effective compared with FOV with incremental cost-effectiveness ratios of €8,062, €4,179, and €6,127 per quality-adjusted life-years in the three programs, respectively. Sensitivity analyses were consistent with the base cases. Conclusions: A GNV strategy with the 9vHPV vaccine can reduce the burden of HPV-related disease and is cost-effective compared with FOV for both regional vaccination programs and the national catch-up program in Belgium.

Abstract
Background HPV screening has been shown to be more cost-effective than cytology screening under most scenarios. Furthermore, it should be offered only in organized programmes with good quality assurance mechanisms. This study analyses the comparative cost of the current policy of opportunistic cytology screening vs. a hypothetical organized programme based on primary HPV screening. Methods Total cervical cancer expenditure was defined as the sum of three cost elements: (i) direct (medical and non-medical) costs, obtained from a calibrated Markov model of the natural history of HPV and cervical cancer; (ii) programmatic costs, estimated based on other organized screening programmes; and (iii) indirect costs, extrapolated from previously published data. Results Organized HPV screening at 5-year intervals costs consistently less across all coverage levels than opportunistic cytology screening at 3-year intervals. The current annual direct medical cost to the public health system of the opportunistic cytology at 40% coverage is estimated at €33.2 per woman screened aged 25-64. Under an organized programme of primary HPV screening at 70% coverage, the cost is estimated to be €18.4 per woman screened aged 25-64. Conclusion Our study concludes that the economic resources currently devoted to providing opportunistic cytology screening to 40% of the target population at 3-year intervals could be more effectively used to screen 70% of the target population at 5-year intervals by switching to an organized programme based on primary HPV screening. This finding is of relevance to other European countries or regions with similar screening policies and health infrastructures.

Abstract
BACKGROUND Many economic evaluations of human papillomavirus vaccination should ideally consider multiple disease outcomes, including anogenital warts, respiratory papillomatosis and non-cervical cancers (eg, anal, oropharyngeal, penile, vulvar and vaginal cancers). However, published economic evaluations largely relied on estimates from single studies or informal rapid literature reviews. METHODS We conducted a systematic review of articles up to June 2016 to identify costs and utility estimates admissible for an economic evaluation from a single-payer healthcare provider's perspective. Meta-analyses were performed for studies that used same utility elicitation tools for similar diseases. Costs were adjusted to 2016/2017 US$. RESULTS Sixty-one papers (35 costs; 24 utilities; 2 costs and utilities) were selected from 10 742 initial records. Cost per case ranges were US$124-US$883 (anogenital warts), US$6912-US$52 579 (head and neck cancers), US$12 936-US$51 571 (anal cancer), US$17 524-34 258 (vaginal cancer), US$14 686-US$28 502 (vulvar cancer) and US$9975-US$27 629 (penile cancer). The total cost for 14 adult patients with recurrent respiratory papillomatosis was US$137 601 (one paper).Utility per warts episode ranged from 0.651 to 1 (12 papers, various utility elicitation methods), with pooled mean EQ-5D and EQ-VAS of 0.86 (95% CI 0.85 to 0.87) and 0.74 (95% CI 0.74 to 0.75), respectively. Fifteen papers reported utilities in head and neck cancers with range 0.29 (95% CI 0.0 to 0.76) to 0.94 (95% CI 0.3 to 1.0). Mean utility reported ranged from 0.5 (95% CI 0.4 to 0.61) to 0.65 (95% CI 0.45 to 0.75) (anal cancer), 0.59 (95% CI 0.54 to 0.64) (vaginal cancer), 0.65 (95% CI 0.60 to 0.70) (vulvar cancer) and 0.79 (95% CI 0.74 to 0.84) (penile cancer). CONCLUSIONS Differences in values reported from each paper reflect variations in cancer site, disease stages, study population, treatment modality/setting and utility elicitation methods used. As patient management changes over time, corresponding effects on both costs and utility need to be considered to ensure health economic assumptions are up-to-date and closely reflect the case mix of patients.

Abstract
OBJECTIVES To estimate the cost effectiveness of introducing the quadrivalent human papillomavirus (HPV) vaccine into the national immunization program of Iran. METHODS The CERVIVAC cost-effectiveness model was used to calculate incremental cost per averted disability-adjusted life-year by vaccination compared with no vaccination from both governmental and societal perspectives. Calculations were based on epidemiologic parameters from the Iran National Cancer Registry and other national data sources as well as from literature review. We estimated all direct and indirect costs of cervical cancer treatment and vaccination program. All future costs and benefits were discounted at 3% per year and deterministic sensitivity analysis was used. RESULTS During a 10-year period, HPV vaccination was estimated to avert 182 cervical cancer cases and 20 deaths at a total vaccination cost of US $23,459,897; total health service cost prevented because of HPV vaccination was estimated to be US $378,646 and US $691,741 from the governmental and societal perspective, respectively. Incremental cost per disability-adjusted life-year averted within 10 years was estimated to be US $15,205 and US $14,999 from the governmental and societal perspective, respectively, and both are higher than 3 times the gross domestic product per capita of Iran (US $14,289). Sensitivity analysis showed variation in vaccine price, and the number of doses has the greatest volatility on the incremental cost-effectiveness ratio. Using a two-dose vaccination program could be cost-effective from the societal perspective (incremental cost-effectiveness ratio = US $11,849). CONCLUSIONS Introducing a three-dose HPV vaccination program is currently not cost-effective in Iran. Because vaccine supplies cost is the most important parameter in this evaluation, considering a two-dose schedule or reducing vaccine prices has an impact on final conclusions.

Abstract
BACKGROUND The total direct cost of screening and treating all human papillomavirus-related diseases (HPV-RD) has not been measured in a single study. Accurate cost estimates are needed to inform decisions on intervention priorities and evaluate the cost-effectiveness of existing programs. We used province-wide clinical, administrative, and accounting databases to measure direct medical costs of HPV infection in Manitoba (Canada). METHODS All persons 9 years or older with health insurance coverage in Manitoba between April 2000 and March 2015 were eligible. We identified all persons with an incident HPV-RD and aggregated all medical costs (in 2014 Canadian dollars) related to that condition, including prescription drugs, diagnostic procedures, in-hospital and outpatient treatment, and physician visits. RESULTS We found that the median cost of treating a case of anogenital warts was $130. An episode of cervical dysplasia had a median cost of $220, compared to $1300 for an episode of cervical carcinoma in situ. The cost of treating HPV-related invasive cancer varied from $15,000 for cervical cancer to $33,000 for oral cavity cancer. Overall, 80% ($145 million) of the total cost was attributable to HPV infection. Cervical screening and follow-up accounted for $96 million (66%) of all costs and this cost component has declined following the introduction of new screening guidelines. CONCLUSIONS Overall, the average direct medical cost of HPV infection was $720 per newborn. The economic burden of HPV remains significant, although changes in cervical screening guidelines, prompted by the introduction of a public HPV vaccine program, appear to have promoted a promising trend towards lower costs.

Abstract
OBJECTIVES Estimate the prevalence of genital warts (GW) and GW-related healthcare resource use and costs among male and female patients seeking treatment in South Korea. DESIGN To estimate GW prevalence, physicians in five major South Korean regions recorded daily logs of patients (n=71 655) seeking care between July 26 and September 27, 2011. Overall prevalence estimates (and 95% CIs) were weighted by the estimated number of physicians in each specialty and the estimated proportion of total patients visiting each specialist type. Healthcare resource use was compared among different specialties. Corresponding p values were calculated using Mann-Whitney U tests. SETTING The database covers 5098 clinics and hospitals for five major regions in South Korea: Seoul, Busan, Daegu, Gwangju and Daejeon. PARTICIPANTS Primary care physicians (general practice/family medicine), obstetricians/gynaecologists, urologists and dermatologists with 2-30 years' experience. RESULTS The estimated overall GW prevalence was 0.7% (95% CI 0.7% to 0.8%). Among women, GW prevalence was 0.6% (95% CI 0.6% to 0.7%); among men prevalence was 1.0% (95% CI 0.9% to 1.0%), peaking among patients aged 18-24 years. Median costs for GW diagnosis and treatment for male patients were US$58.2 (South Korean Won (KRW) ₩66 857) and US$66.3 (KRW₩76 113) for female patients. CONCLUSIONS The estimated overall GW prevalence in South Korea was 0.7% and was higher for male patients. The overall median costs associated with a GW episode were higher for female patients than for male patients.

Abstract
BACKGROUND Human papillomavirus (HPV) has proven to be the cause of several severe clinical conditions on the cervix, vulva, vagina, anus, oropharynx and penis. Several studies have assessed the costs of cervical lesions, cervical cancer (CC), and genital warts. However, few have been done in Africa and none in Swaziland. Cost analysis is critical in providing useful information for economic evaluations to guide policymakers concerned with the allocation of resources in order to reduce the disease burden. MATERIALS AND METHODS A prevalence-based cost of illness (COI) methodology was used to investigate the economic burden of HPV-related diseases. We used a top-down approach for the cost associated with hospital care and a bottom-up approach to estimate the cost associated with outpatient and primary care. The current study was conducted from a provider perspective since the state bears the majority of the costs of screening and treatment in Swaziland. All identifiable direct medical costs were considered for cervical lesions, cervical cancer and genital warts, which were primary diagnoses during 2015. A mix of bottom up micro-costing ingredients approach and top-down approaches was used to collect data on costs. All costs were computed at the price level of 2015 and converted to dollars ($). RESULTS The total annual estimated direct medical cost associated with screening, managing and treating cervical lesions, CC and genital warts in Swaziland was $16 million. The largest cost in the analysis was estimated for treatment of high-grade cervical lesions and cervical cancer representing 80% of the total cost ($12.6 million). Costs for screening only represented 5% of the total cost ($0.9 million). Treatment of genital warts represented 6% of the total cost ($1million). CONCLUSION According to the cost estimations in this study, the economic burden of HPV-related cervical diseases and genital warts represents a major public health issue in Swaziland. Prevention of HPV infection with a national HPV immunization programme for pre-adolescent girls would prevent the majority of CC related deaths and associated costs.

Abstract
BACKGROUND Typically occurring on the external genitalia, anogenital warts (AGWs) are benign epithelial skin lesions caused by human papillomavirus infection. AGWs are usually painless but can be unsightly and physically uncomfortable, and affected people might experience psychological distress. The evidence base on the clinical effectiveness and cost-effectiveness of treatments for AGWs is limited. OBJECTIVES To systematically review the evidence on the clinical effectiveness of medical and surgical treatments for AGWs and to develop an economic model to estimate the cost-effectiveness of the treatments. DATA SOURCES Electronic databases (MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, EMBASE, The Cochrane Library databases and Web of Science) were searched from inception (or January 2000 for Web of Science) to September 2014. Bibliographies of relevant systematic reviews were hand-searched to identify potentially relevant studies. The World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov were searched for ongoing and planned studies. REVIEW METHODS A systematic review of the clinical effectiveness literature was carried out according to standard methods and a mixed-treatment comparison (MTC) undertaken. The model implemented for each outcome was that with the lowest deviance information criterion. A de novo economic model was developed to assess cost-effectiveness from the perspective of the UK NHS. The model structure was informed through a systematic review of the economic literature and in consultation with clinical experts. Effectiveness data were obtained from the MTC. Costs were obtained from the literature and standard UK sources. RESULTS Of 4232 titles and abstracts screened for inclusion in the review of clinical effectiveness, 60 randomised controlled trials (RCTs) evaluating 19 interventions were included. Analysis by MTC indicated that ablative techniques were typically more effective than topical interventions at completely clearing AGWs at the end of treatment. Podophyllotoxin 0.5% solution (Condyline(®), Takeda Pharmaceutical Company Ltd; Warticon(®) solution, Stiefel Laboratories Ltd) was found to be the most effective topical treatment evaluated. Networks for other outcomes included fewer treatments, which restrict conclusions on the comparative effectiveness of interventions. In total, 84 treatment strategies were assessed using the economic model. Podophyllotoxin 0.5% solution first line followed by carbon dioxide (CO2) laser therapy second line if AGWs did not clear was most likely to be considered a cost-effective use of resources at a willingness to pay of £20,000-30,000 per additional quality-adjusted life-year gained. The result was robust to most sensitivity analyses conducted. LIMITATIONS Limited reporting in identified studies of baseline characteristics for the enrolled population generates uncertainty around the comparability of the study populations and therefore the generalisability of the results to clinical practice. Subgroup analyses were planned based on type, number and size of AGWs, all of which are factors thought to influence treatment effect. Lack of data on clinical effectiveness based on these characteristics precluded analysis of the differential effects of treatments in the subgroups of interest. Despite identification of 60 studies, most comparisons in the MTC are informed by only one RCT. Additionally, lack of head-to-head RCTs comparing key treatments, together with minimal reporting of results in some studies, precluded comprehensive analysis of all treatments for AGWs. CONCLUSIONS The results generated by the MTC are in agreement with consensus opinion that ablative techniques are clinically more effective at completely clearing AGWs after treatment. However, the evidence base informing the MTC is limited. A head-to-head RCT that evaluates the comparative effectiveness of interventions used in clinical practice would help to discern the potential advantages and disadvantages of the individual treatments. The results of the economic analysis suggest that podophyllotoxin 0.5% solution is likely to represent a cost-effective first-line treatment option. More expensive effective treatments, such as CO2 laser therapy or surgery, may represent cost-effective second-line treatment options. No treatment and podophyllin are unlikely to be considered cost-effective treatment options. There is uncertainty around the cost-effectiveness of treatment with imiquimod, trichloroacetic acid and cryotherapy. STUDY REGISTRATION This study is registered as PROSPERO CRD42013005457.

Abstract
Vaccines are available against human papillomavirus (HPV), the causal agent of cervical and other cancers. Efficacy data from the HPV-16/18 AS04-adjuvanted vaccine clinical trial program were reviewed. Six randomized, controlled phase II/III trials evaluating cervical endpoints enrolled women from diverse populations and geographical locations. The program analyzed extensively the cohorts most relevant from a public health perspective: the total vaccinated cohort (TVC), approximating a general population including those with existing or previous HPV infection, and TVC-naïve, approximating a population of young women before sexual debut. Results show that the vaccine reduces HPV-16/18 infection and associated cervical endpoints in women regardless of age, location, or sexual experience. It provides cross-protection against some non-vaccine oncogenic HPV types and types causing genital warts, and may be effective against vulvar, oral, and anal HPV infection. Early epidemiology data following its introduction suggest a decline in the prevalence of vaccine and some non-vaccine HPV types.

Abstract
BACKGROUND New chemotherapy combinations are being tested for the treatment of women with advanced, persistent or recurrent cervical cancer. We sought to evaluate the cost effectiveness of some newer combination therapies in cervical cancer. PATIENTS AND METHODS A cost effectiveness decision model was used to analyze Gynecologic Oncology Group 240. All regimens were modeled for seven cycles. The regimens studied are as follows: regimen 1, cisplatin/paclitaxel (CP); regimen 2, CP with bevacizumab (CP+B); regimen 3, paclitaxel/topotecan (PT); and regimen 4, PT with bevacizumab (PT+B). Overall survival, cost, and complications were studied. Sensitivity analyses were performed. RESULTS Mean chemotherapy costs over mean total costs for seven cycles of each follows: CP $571/$32,966; CP+B $61,671/$96,842; PT $9,211/$71,620; and PT+B $70,312/$109,211. Incremental cost-effectiveness ratio (ICER) for CP+B was $133,559/quality adjusted life year (QALY). ICER for PT+B was $124,576/QALY. To achieve an incremental ICER for CP+B:CP of <$50,000/QALY gained, the mean overall survival has to increase from 1.1 years with CP to 3.5 years with CP+B. An ICER <$50,000/QALY for the other regimens would take a survival of >10 years for PT and 4.1 years for PT+B. Treating 1,000 women with cervical cancer with CP+B would cost almost double the cost of treating >18,000 women with ovarian cancer annually (carboplatin/paclitaxel). CONCLUSION CP is the most cost effective regimen. A 12-month increase in overall survival will not even make the newer combinations cost effective. Currently, the use of bevacizumab is not sustainable at today's costs.

Abstract
OBJECTIVES We set out to assess the health care resource utilization and cost of cervical cancer from the perspective of a single-payer health care system. METHODS Retrospective observational data for women diagnosed with cervical cancer in British Columbia between 2004 and 2009 were analyzed to calculate patient-level resource utilization patterns from diagnosis to death or 5-year discharge. Domains of resource use within the scope of this cost analysis were chemotherapy, radiotherapy, and brachytherapy administered by the BC Cancer Agency; resource utilization related to hospitalization and outpatient visits as recorded by the B.C. Ministry of Health; medically required services billed under the B.C. Medical Services Plan; and prescriptions dispensed under British Columbia's health insurance programs. Unit costs were applied to radiotherapy and brachytherapy, producing per-patient costs. RESULTS The mean cost per case of treating cervical cancer in British Columbia was $19,153 (standard error: $3,484). Inpatient hospitalizations, at 35%, represented the largest proportion of the total cost (95% confidence interval: 32.9% to 36.9%). Costs were compared for subgroups of the total cohort. CONCLUSIONS As health care systems change the way they manage, screen for, and prevent cervical cancer, cost-effectiveness evaluations of the overall approach will require up-to-date data for resource utilization and costs. We provide information suitable for such a purpose and also identify factors that influence costs.

Abstract
Objective Costs associated with HPV-related diseases such as cervical dysplasia, cervical cancer, and genital warts have not been evaluated in Sweden. These costs must be estimated in order to determine the potential savings if these diseases were eradicated and to assess the combined cost-effectiveness of HPV vaccination and cervical cancer screening. The present study aimed to estimate prevention, management, and treatment costs associated with cervical dysplasia, cervical cancer, and genital warts from a societal perspective in Sweden in 2009, 1 year before the quadrivalent HPV vaccination program was implemented. Methods and Materials Data from the Swedish cervical cancer screening program was used to calculate the costs associated with prevention (cytological cervical cancer screening), management (colposcopy and biopsy following inadequate/abnormal cytological results), and treatment of CIN. Swedish official statistics were used to estimate treatment costs associated with cervical cancer. Published epidemiological data were used to estimate the number of incident, recurrent, and persistent cases of genital warts; a clinical expert panel assessed management and treatment procedures. Estimated visits, procedures, and use of medications were used to calculate the annual cost associated with genital warts. Results From a societal perspective, total estimated costs associated with cervical cancer and genital warts in 2009 were €106.6 million, of which €81.4 million (76%) were direct medical costs. Costs associated with prevention, management, and treatment of CIN were €74 million; screening and management costs for women with normal and inadequate cytology alone accounted for 76% of this sum. The treatment costs associated with incident and prevalent cervical cancer and palliative care were €23 million. Estimated costs for incident, recurrent and persistent cases of genital warts were €9.8 million. Conclusion Prevention, management, and treatment costs associated with cervical dysplasia, cervical cancer, and genital warts are substantial. Defining these costs is important for future cost-effectiveness analyses of the quadrivalent HPV vaccination program in Sweden.

Evaluating the Early Benefit of Quadrivalent HPV Vaccine on Genital Warts in Belgium: A Cohort Study. PLoS One 2015; 10:e0132404. [PMID: 26147096 PMCID: PMC4492693 DOI: 10.1371/journal.pone.0132404] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2015] [Accepted: 06/14/2015] [Indexed: 11/21/2022] Open
Abstract
Genital warts (GWs) are common, with about 5% to 10% of people having at least one episode in their lifetime. They develop about 2–3 months after infection with human papillomavirus (HPV) genotypes 6 and 11. The prophylactic quadrivalent HPV vaccine (qHPV), protects against HPV6/11 infections and diseases. In Belgium, HPV vaccines started to be reimbursed in 2007 and have been fully reimbursed since December 2008 for women 12 to 18 years old. This study aimed at evaluating the real-life benefit of qHPV vaccine introduction in Belgium on GWs by measuring both vaccine impact (VI) at a population level and the direct effect of the qHPV vaccine at an individual level (vaccine effectiveness (VE)), using data from a large sick-fund (MLOZ) reimbursement database. A first reimbursement for imiquimod (most common first-line GWs treatment in Belgium) was used as a surrogate for a first GWs episode; reimbursement of qHPV vaccine was used as surrogate for vaccination. VI was estimated by comparing the incidence of GWs before and after qHPV vaccine introduction in Belgium (ecologic evaluation). VE was assessed by comparing GWs incidences in vaccinated vs. unvaccinated women, among women eligible for HPV vaccination. VI was evaluated in 9,223,384 person-years. Overall, GWs incidence rates decreased significantly between the pre- and post-vaccination periods (-8.1% (95% CI: -15.3; -0.3) for men and women aged 18–59 years. This decrease was highest in women targeted by the HPV vaccination programme (-72.1% (95% CI: -77.9; -64.7) in women aged 16–22 years, with a 43% vaccine uptake in 2013). A significant decrease was also observed in men aged 16-22 years (-51.1%, 95%CI: -67.6; -26.2), suggesting herd-protection. VE was evaluated in 369,881 person-years. Age-adjusted VE for fully vaccinated women was 88.0% (95% CI: 79.4; 93.0). VE was higher when the first dose was given younger and remained high for over 4 years post-vaccination in all ages. High VI and VE of the qHPV vaccine were observed in a real-life setting in Belgium.

Abstract
OBJECTIVE To estimate the annual direct and indirect costs of the prevention and treatment of cervical cancer in Brazil. METHODS This cost description study used a "gross-costing" methodology and adopted the health system and societal perspectives. The estimates were grouped into sets of procedures performed in phases of cervical cancer care: the screening, diagnosis and treatment of precancerous lesions and the treatment of cervical cancer. The costs were estimated for the public and private health systems, using data from national health information systems, population surveys, and literature reviews. The cost estimates are presented in 2006 USD. RESULTS From the societal perspective, the estimated total costs of the prevention and treatment of cervical cancer amounted to USD $1,321,683,034, which was categorized as follows: procedures (USD $213,199,490), visits (USD $325,509,842), transportation (USD $106,521,537) and productivity losses (USD $676,452,166). Indirect costs represented 51% of the total costs, followed by direct medical costs (visits and procedures) at 41% and direct non-medical costs (transportation) at 8%. The public system represented 46% of the total costs, and the private system represented 54%. CONCLUSION Our national cost estimates of cervical cancer prevention and treatment, indicating the economic importance of cervical cancer screening and care, will be useful in monitoring the effect of the HPV vaccine introduction and are of interest in research and health care management.

Estimation of the potential overall impact of human papillomavirus vaccination on cervical cancer cases and deaths. Vaccine 2013; 32:733-9. [PMID: 24291200 DOI: 10.1016/j.vaccine.2013.11.049] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2013] [Revised: 10/30/2013] [Accepted: 11/17/2013] [Indexed: 11/22/2022]
Abstract
BACKGROUND Human papillomavirus (HPV) vaccination offers potential for primary prevention of HPV-related pre-cancers and cancers as demonstrated in clinical trials. Mathematical models have estimated the potential real-life impact of vaccination on the burden of cervical cancer (CC). However, these are restricted to evaluations in a limited number of countries. METHODS Potential decline in CC cases and deaths with the AS04-adjuvanted HPV-16/18 vaccine of young girls naïve to HPV, was estimated at steady-state (vaccine coverage: 0-100%) based on clinical trial and country-specific incidence data. Data on vaccine efficacy were taken from the end of study PATRICIA trial of the AS04-adjuvanted HPV-16/18 vaccine. The numbers of cases and deaths due to HPV-16/18 were estimated and compared with those due to any HPV type to estimate the additional cases prevented. This difference estimates CC cases and deaths avoided due to protection against non-vaccine HPV types. Cost-offsets due to reductions in CC treatment were estimated for five countries (Brazil, Canada, Italy, Malaysia and South African Republic) using country-specific unit cost data. Additionally, cervical intraepithelial neoplasia grade 2 or 3 (CIN2/3)-related burden (cases and treatment costs) prevented by vaccination were estimated for two countries (Italy and Malaysia). RESULTS HPV vaccination could prevent a substantial number of CC cases and deaths in countries worldwide, with associated cost-offsets due to reduced CC treatment. Cross-protection increased the estimated potential number of CC cases and deaths prevented by 34 and 18% in Africa and Oceania, respectively. Moreover, vaccination could result in a substantial reduction in the number of CIN2/3 lesions and associated costs. CONCLUSION HPV vaccination could reduce the burden of CC and precancerous lesions in countries worldwide, part of disease burden reduction being related to protection against non HPV-16/18 related types.

Abstract
OBJECTIVES More than 1.5 million patients worldwide are affected by bone metastases. Patients with bone metastases frequently develop skeletal-related events (SREs, including radiation to bone, non-vertebral fracture, vertebral fracture, surgery to bone, and spinal cord compression) that are associated with high healthcare costs. This study aims to provide an estimate of the cost per SRE in both the inpatient and outpatient settings in Belgian patients with bone metastases secondary to solid tumors (breast, prostate, and lung cancers). METHODS Patients were retrieved from the IMS Hospital Disease database from 2005-2007. Inclusion was based on the International Classification of Diseases and Related Health Problems Version 9 (ICD-9) diagnosis and/or procedure codes covering patients with breast, prostate, or lung cancer with bone metastases who were hospitalized for one or more SREs. All costs were extrapolated to 2010 using progression in hospitalization costs since 2001. Additional outpatient costs resulting from radiation to bone and diagnostic tests performed in ambulatory settings were estimated by combining published unit costs with resource use data obtained from a Delphi panel. RESULTS The average cost per SRE across solid tumor types based on the weighted average of inpatient and outpatient costs was €2653 for radiation to bone, €5015 for a vertebral fracture, and €7087 for a non-vertebral fracture. Costs were €12,885 and €15,267 for surgery to bone and spinal cord compression, respectively. LIMITATIONS No patient follow-up across calendar years could be done. Also, details regarding the exact anatomic sites of SREs were not always available. CONCLUSIONS SREs add a substantial cost to the management of patients with bone metastases. Avoiding SREs can lead to important cost-savings for the healthcare payer.

Abstract
Background: Trials have demonstrated improvements in survival with adding paclitaxel (P) or topotecan (T) to cisplatin (C) for the treatment of advanced cervical cancer. We sought to evaluate the cost effectiveness of these regimens. Methods: A decision model was developed based on Gynecologic Oncology Group (GOG) protocols 169 and 179. Arm 1 is 6 cycles of cisplatin. Arm 2 is 6 cycles of CP while arm 3 is 6 cycles of CT. Parameters include overall survival (OS), cost and complications. Sensitivity analyses were performed. Results: The incremental cost-effectiveness ratio (ICER) for C versus CP is $13,654/quality-adjusted life-year (QALY) gained. For CT compared to C, the ICER is $152,327/QALY. When compared simultaneously, CT is dominated. At a willingness to pay (WTP) threshold of $50,000/QALY, C is the preferred option but CP is acceptable. Sensitivity analyses suggest that CT would become the preferred option if it was to improve OS to 24 months (compared to 9.4 months). Conclusions: In this model, CP is an acceptable alternative to cisplatin for the treatment of these patients with an increase in cost of only $13,654/QALY. The addition of topotecan did not increase survival enough to justify the increased cost.

Abstract
BACKGROUND Sexually transmitted human papillomavirus (HPV) high-risk types cause carcinoma and low-risk types lead to warts of genitoanal area. Since the HPV vaccine has been introduced, awareness of HPV infection, prevention and health-related behaviour have not been studied in a large sample of young women in Germany. OBJECTIVES Assessment of awareness and health-related behaviour regarding HPV infection and prevention among young German females. METHODS In 2010, a postal cross-sectional survey was conducted with a random representative sample size (n = 2000) of females aged 19-35 attending Germany's largest (comprehensive) university, which was designed to obtain data about socio-demographics, the awareness of sexually transmitted HPV, genitoanal neoplasms and their prevention, HPV vaccine, immunisation and cervical cancer screening. RESULTS Of the 547 (27.3%) participants, 69.1% had heard of HPV, 62.5% were aware of the vaccine, 14.4% were vaccinated and 6.9% reported a history of sexually transmitted infection, including HPV (2.7%). The HPV-related knowledge among those who had heard of it was high (75.1-99.7%), except of that HPV affects men (52.9%) and HPV's causative role in genital (54.2%) and anal (35.6%) warts, and smoking (11.3%) as an HPV risk factor. The lower HPV knowledge score (<median = 12, ranged 1-17) was predicted by studying social sciences/humanities (OR = 3.68, 95% CI 1.99-6.79) and non-participation in cervical cancer screening (OR = 2.04, 95% CI 1.02-4.07). CONCLUSION This survey reveals an insufficient HPV awareness and low vaccination prevalence among young German women, underscoring the urgent need for HPV-related education aimed at reducing the burden of HPV-induced genitoanal neoplasms.

Abstract
External genital warts (EGW) are a sexually transmitted infection caused by various strains of human papillomavirus (HPV). Several studies have described the direct and indirect costs of EGW, while others have reported on the burden of EGW in terms of the impact on the quality of life (QOL) of patients. The arrival of a quadrivalent HPV vaccine that protects against both cervical cancer and EGW requires a proper understanding of the impact of vaccines on costs and QOL. Using pre-defined search terms and inclusion/exclusion criteria, we performed a systematic review of the economic and humanistic burden of EGW. The focus of our review was on literature describing the direct and indirect costs of EGW per episode of care (EoC) or per year, as well as the impact of EGW on disease-specific, generic, or preference-based QOL measures. We also reviewed the literature on the national economic burden of EGW from the perspectives of different countries. Other aspects of EGW management that can inform economic modelling studies, such as length of EoC, number of physician visits and indirect costs, were also explored. Our review sheds light on the high economic and humanistic burden of EGW and important differences in the costs between men and women, as well as the differences in health resource utilization and costs across countries. Our study also highlights the dearth of information on the impact of EGW on the QOL and productivity of patients.

Abstract
Human papillomavirus (HPV) infection is associated with a range of diseases and cancers at different anatomical sites. In addition to its role as a necessary cause of cervical cancer, HPV is also associated with cancers of the vulva, vagina, anus, penis, head and neck. With the exception of cervical cancer, however, very few data are available on the economic burden of HPV-associated cancers. We assessed the annual costs associated with management of HPV-related cancers in France from the healthcare payers' perspective. We used data from studies that employed similar methodologies to estimate the costs during 2006 for cervical cancer, vulvar and vaginal cancers, anal cancer, and penile cancer, and during 2007 for head and neck cancers. Data on hospital-management costs for cancer were derived from the French national hospital database. The costs of outpatient care and daily allowance costs were estimated using data from the French National Institute of Cancer report for 2007. The costs for HPV-related cancers were estimated according to the percentage of each cancer type attributable to HPV infection. The estimated total costs associated with HPV-related cancers in France were €239.7 million. The overall costs in men were €107.2 million, driven mainly by head and neck cancers (€94.6 million). The total costs in women were €132.5 million, due mainly to invasive cervical cancer (€83.9 million). The costs associated with HPV-related cancers are important to consider when evaluating the overall benefits of HPV vaccination in males and females.

Abstract
OBJECTIVES It is known that infections with human papillomavirus (HPV) types 6, 11, 16, and 18, cause cervical cancers (CC), cervical intraepithelial neoplastic lesions (types 1 to 3; CIN 1-3), and genital warts (GW). Together with equivocal cytological abnormalities (ECA), these place a considerable burden on society, but the costs and resource usage are not easily estimated. Therefore, we undertook this study to estimate the burden and costs associated with HPV-related diseases. METHODS We used Finnish registry-based data for CC, CIN 1-3 and ECA. Data on GW were estimated from associated procedures and medications. The annual burden of disease was estimated from hospitalizations, visits to specialists and primary level care, and pharmaceutical use. The evaluation of costs included health care and screening costs, and productivity lost (separately). Due to the data obtained being fragmented, 2 cost scenarios were constructed. RESULTS The follow-up of ECA appears to be the most important cost driver. GW should not be underestimated as they affect both genders at an early age. CONCLUSIONS HPV infections are a burden to society, not only as a result of cancer-related costs, but also costs related to other diseases and indirect costs in the form of lost productivity.

Abstract
BACKGROUND The introduction of a quadrivalent human papillomavirus (HPV; types 6, 11, 16, 18) vaccine is expected to significantly reduce the burden of cervical cancer, cervical intraepithelial neoplasia (CIN), genital warts and other HPV-related diseases. OBJECTIVE To determine the cost effectiveness of providing a quadrivalent (6,11,16,18) HPV vaccine programme in adolescent females aged 12 years in addition to the existing cervical cancer screening programme in Belgium. METHODS A Markov state-transition model was developed for the Belgian context in order to evaluate the long-term impact of vaccinating a cohort of girls aged 12 years alongside the existing screening programme. Women were followed until the age of 85 years. A vaccine that would prevent 100% of diseases associated with HPV-6, -11, -16 and -18, with lifetime duration of efficacy, 80% coverage, in conjunction with current screening, was compared with screening alone. For this analysis, 35% of cases of CIN-1, 55% of CIN-2/3, 75% of cervical cancer and 90% of genital warts were considered to be attributable to HPV-6, -11, -16 or -18. The model estimated lifetime risks and total lifetime healthcare costs, survival and QALYs for cervical cancer, CIN and genital warts. Outcomes validation was applied. Model outcomes also included incremental costs per life-year gained and incremental costs per QALY gained. The analysis was conducted from the perspective of the Belgian healthcare payer, and costs were in year 2006 values. RESULTS The model estimated a reduction in the lifetime risk of cervical cancer from 0.94% to 0.34%, therefore preventing 362 cases of cervical cancer and 131 related deaths in a cohort of 60,000 girls aged 12 years in Belgium. The base-case scenario suggests quadrivalent HPV vaccination in addition to current cervical screening in Belgium to be cost effective at euro 10,546 per QALY. This is within the accepted range of cost-effective interventions in Europe. This cost effectiveness is maintained for different parameter assumptions in the sensitivity analysis, with the exception of very high discount rates for costs and medical benefits, but, even in the worst case, ratios were still less than euro 50,000 per QALY. Even when a separate scenario modelled the requirement for a booster vaccination to sustain a lifetime duration of protection, the results remained cost effective at eruo 17,388 per QALY. CONCLUSIONS Vaccination with a quadrivalent HPV vaccine appears to be a cost-effective public health intervention in conjunction with the existing screening programme in Belgium. The additional costs of introducing vaccination to the established screening programme would be offset by the potential savings from not having to treat the diseases caused by HPV-6, -11, -16 or -18.
