Quality-adjusted life years for HER2-positive, early-stage breast cancer using trastuzumab-containing regimens in the context of cost-effectiveness studies: a systematic review.

INTRODUCTION: This study aims to provide a comprehensive assessment of economic and health-related quality of life (HRQoL) outcomes for human epidermal growth factor receptor 2 (HER2)-positive, early-stage breast cancer patients treated with trastuzumab-containing regimens, by focusing on both Incremental Cost-Effectiveness Ratios (ICERs) and quality-adjusted life years (QALYs). METHODS: A systematic search was conducted across PubMed, Embase, and Scopus databases without language or publication year restrictions. Two independent reviewers screened eligible studies, extracted data, and assessed methodology and reporting quality using the Drummond checklist and Consolidated Health Economic Evaluation Reporting Standards 2022 (CHEERS 2022), respectively. Costs were converted to US dollars (US$) for 2023 for cross-study comparison. RESULTS: Twenty-two articles, primarily from high-income countries (HICs), were included, with ICERs ranging from US$13,176/QALY to US$254,510/QALY, falling within country-specific cost-effectiveness thresholds. A notable association was observed between higher QALYs and lower ICERs, indicating a favorable cost-effectiveness and health outcome relationship. EQ-5D was the most utilized instrument for assessing health state utility values, with diverse targeted populations. CONCLUSIONS: Studies reporting higher QALYs tend to have lower ICERs, indicating a positive relationship between cost-effectiveness and health outcomes. However, challenges such as methodological heterogeneity and transparency in utility valuation persist, underscoring the need for standardized guidelines and collaborative efforts among stakeholders.

Economic evaluation of trastuzumab in HER2-positive early breast cancer in Indonesia: A cost-effectiveness analysis.

BACKGROUND: Trastuzumab has significantly enhanced the survival and prognosis of individuals diagnosed with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer. Considering its relatively high costs, we aimed to examine the cost-effectiveness of trastuzumab plus chemotherapy compared with chemotherapy alone in HER2-positive early breast cancer from an Indonesian healthcare payer's perspective. METHODS: A Markov model was developed to project the lifetime health benefits and costs associated with trastuzumab treatment for a cohort of women with HER2-positive early breast cancer. Efficacy data and baseline characteristics in the base-case analysis were primarily derived from the 11-year results of the HERA trial. Costs were based on verified reimbursement data from Indonesia's Health and Social Security Agency (BPJS Kesehatan) of the year 2020. A scenario analysis was conducted with efficacy data based on the joint analysis from the NSABP B-31 and NCCTG N9831 trials, allowing for subgroup analysis by age at diagnosis. Univariate and probabilistic sensitivity analyses were conducted to assess the influence of parameter uncertainty. RESULTS: In the base-case analysis, the results indicated that the lifetime costs for trastuzumab plus chemotherapy and chemotherapy alone were US$33,744 and US$22,720, respectively, resulting in substantial incremental savings of US$11,024 per patient for the former. Trastuzumab plus chemotherapy also led to higher total quality-adjusted life years (QALYs) and life years gained (LYG), resulting in incremental cost-effectiveness ratios (ICERs) of US$6,842 per QALY and US$5,510 per LYG. In scenario analysis, the subgroup with an age at diagnosis <40 years old reflected the most cost-effective subgroup. Both the base-case and scenario analyses demonstrated cost-effectiveness with a willingness-to-pay threshold of three-times Gross Domestic Product (GDP). Sensitivity analyses confirmed the robustness of the findings and conclusions. CONCLUSION: In Indonesia, trastuzumab plus chemotherapy can be considered cost-effective compared to chemotherapy alone at a willingness-to-pay threshold of three times GDP, and it is likely most cost-effective in women <40 years of age.

A Systematic Review of Health-Related Quality of Life in Women with HER2-Positive Metastatic Breast Cancer Treated with Trastuzumab.

BACKGROUND: Many trials of human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer treatment with trastuzumab have provided evidence of improved clinical outcomes. This systematic review examined how a regimen that includes trastuzumab affects patients' health-related quality of life (HRQoL) during and after treatment. METHODS: A systematic search for articles published up to February 2023 without restrictions of language or publication year was performed using the Pubmed, Embase, and Scopus databases. We included studies of women aged > 18 years with metastatic HER2-positive breast cancer treated with a trastuzumab-containing regimen. We assessed the quality of the studies using the Cochrane Risk of Bias (RoB) tool (2.0) for randomized controlled trials (RCTs) and the Risk Of Bias In Non-randomised Studies-of Interventions (ROBINS-I) tool for cross-sectional studies. We used Microsoft Excel to extract and synthesize data, and documented the review procedure following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: In total, eight studies compared 1104 trastuzumab-treated patients and 1003 non-trastuzumab-treated patients. Most studies were RCTs (n = 7) and one was a prospective observational study. All the included studies used the EORTC-QLQ-C30, EORTC-QLQ-BR23, FACT-B, or FACT-G questionnaires. During treatment, patients taking regimens that included trastuzumab showed clinical improvement in HRQoL, social functioning, and role functioning. After the treatment, patients' HRQoL profiles in the trastuzumab and chemotherapy arms were similar. However, trastuzumab (versus chemotherapy) treatment led to clinically improved functional status, role and physical functioning, and fatigue. The quality assessment revealed some concerns in most RCTs, with the risk of bias being high in two studies, low in one study, and moderate in the cross-sectional study. CONCLUSIONS: Trastuzumab-containing regimens administered to HER2-positive breast cancer patients at the metastatic stage evidenced beneficial effects on total HRQoL during and after treatment. Upon therapy cessation, patients' HRQoL scores for both interventions improved. Nevertheless, HRQoL profiles of patients treated with trastuzumab were more favorable, particularly for functional status, role functioning, physical well-being, and fatigue. CLINICAL TRIALS REGISTRATION: This review was registered in PROSPERO (registration number: CRD42021259826).

The clinical effectiveness of one-dose vaccination with an HPV vaccine: A meta-analysis of 902,368 vaccinated women.

BACKGROUND: The comprehensive effectiveness of the HPV vaccine has been widely acknowledged. However, challenges such as dosing adherence and limited budgets have led to delays in HPV vaccination implementation in many countries. A potential solution to these issues could lie in a one-dose vaccination with an HPV vaccine, as indicated by promising outcomes in multiple studies. METHODS: In this systematic review and meta-analysis, we examine the comparative effectiveness of the one-dose vaccination with an HPV vaccine against two- and three-dose regimens. Our investigation focuses on clinical efficacy, encompassing the prevention of HPV16, HPV18, and hrHPV infections, HSIL or ASC-H incidence, and CIN2/3 incidence. RESULTS: Our analysis suggests that a single-dose HPV vaccine may offer effectiveness on par with two- or three-dose schedules. This conclusion is drawn from its capacity to confer immunogenic protection for at least 8 years of follow-up, coupled with its ability to mitigate infections and pre-cancerous occurrences. CONCLUSION: While our findings underscore the potential of the one-dose vaccination with an HPV vaccine, further research and prolonged study durations are necessary to establish robust evidence supporting this recommendation. As such, continued investigation will be critical for informing vaccination strategies.

Economic and humanistic burden of HPV-related disease in Indonesia: A qualitative analysis.

The burden of human papillomavirus (HPV) and HPV-related cancers and genital warts is increasing in developing countries, including Indonesia. The objective of this study was to qualitatively explore the humanistic and economic burden of these HPV-related diseases in patients in Indonesia. In 2021, in-depth interviews and focus groups were conducted with patients (N = 18) with HPV-related diseases and healthcare professionals (HCPs; N = 10) specialised in treating these patients. Interviews explored the physical, mental, social, and economic burden of HPV-related diseases. Patients emphasised the psychological and social burden of HPV-related diseases, which negatively impacted their mental state and close relationships. Treatment for HPV-related diseases was also associated with a substantial cost, which health insurance only partially alleviated. HCPs understood the physical negative impact of HPV-related diseases, but some understated patients' social, psychological, and financial burden. This research underscores the substantial economic and humanistic burden of HPV-related diseases that could be prevented by vaccination. In addition, it highlights the need for novel interventions to reduce negative psychosocial consequences of HPV-related diseases in Indonesia. Increased HCP education of the broader humanistic impacts of HPV-related diseases may improve patient support and increase awareness for preventive strategy.

Health-related quality of life in Her2-positive early breast cancer woman using trastuzumab: A systematic review and meta-analysis.

Background: Despite the benefits of trastuzumab in many trials, evidence of its impact on health-related quality of life (HRQoL) in early treatment has not been summarized. This study explored the effects of trastuzumab treatment on HRQoL, including pooled meta-analysis, in an effort to provide an integrated assessment of HRQoL for Her2-positive early breast cancer patients. Methods: A comprehensive literature review to February 2023 using three databases, focusing on treatment using trastuzumab during the early stage, was performed. The mean changes from baseline during and after treatment were extracted from the included randomized control trials (RCTs) papers and total HRQoL scores were obtained from cross-sectional studies included. Mean difference (MD) and 95% confidence intervals were assessed by a random effect or fixed effect model based on heterogeneity (I2). Results: A total of ten studies were identified and reviewed, consisting of seven RCTs and three cross-sectional studies. The pooled analysis of the mean change from baseline during treatment resulted in an MD of 1.92 (95% CI = 1.59 to 2.25, p < 0.05, I2 = 0%), favoring the trastuzumab group. A non-significant result of the mean change from baseline after treatment appeared in the analysis of 12-month follow-up. In the cross-sectional studies, pooled analyses of HRQoL showed that trastuzumab meaningfully demonstrated an improved HRQoL profile (MD = 9.29, 95% CI = 1.31 to 17.27, p = 0.02, I2 = 0%). Conclusion: Trastuzumab as a targeted therapy resulted in a favorable effect on HRQoL in the early stages of Her2-positive breast cancer. The findings of significant improvements in patients' HRQoL and less clinically meaningful deterioration in side effects of trastuzumab-containing regimen during treatment were supported by prolonged survival.

The Cost Analysis of Human Papillomavirus Vaccination Program in Indonesia.

OBJECTIVES: This study aimed to analyze and describe the cost of HPV vaccination program in Indonesia. METHODS: This study identified the cost-related HPV vaccination program implemented in Makassar, Manado, and Surabaya cities, Indonesia, according to the previous activities performed. Cost information was collected and analyzed in each specific activity for each cost components, using the HPV vaccination module of the World Health Organization Cervical Cancer Prevention and Control Costing tool. RESULTS: According to the Cervical Cancer Prevention and Control Costing tool, the recurrent costs, both financial and economic costs, dominated the HPV vaccination program costs in Surabaya (US dollars [USD] 264 618; USD 268 724), Makassar (USD 166 852; USD 293 300), and Manado (USD 270 815; USD 270 946), with a total cost of USD 702 285 for financial cost and USD 832 970 for economic cost. Vaccine procurement drives the recurrent cost. CONCLUSIONS: The implementation of demonstration program in Surabaya, Makassar, and Manado cities was considerably succeed. Any prediction related to the cost of implementation of HPV vaccination in Indonesia can be calculated and used to advocate regional or national government.

Facing problems in radiotherapy for breast cancer patients in Yogyakarta, Indonesia: A cohort retrospective study.

BACKGROUND: The aim of this study is to explore problems in radiotherapy for breast cancer patients in Yogyakarta, Indonesia, focusing on overall treatment time (OTT) and completion rate. METHODS: A retrospective cohort study was conducted based on data from the Insurance Unit at a tertiary hospital in Yogyakarta, Indonesia. The study included all female outpatients with breast cancer who were treated with radiotherapy from January to December 2017 and met the inclusion criteria. The primary outcomes were OTT and completion rate. The secondary outcomes included the number of radiotherapy fractions, radiotherapy doses, number of radiotherapy interruption days, and reasons for radiotherapy interruption. The chi-squared and Mann-Whitney U tests were used to assess the differences in outcomes between two insurance schemes (JKN-PBI (Beneficiaries of Health Insurance Contribution Assistance) and JKN-NON-PBI (Non-Beneficiaries of Health Insurance Contribution Assistance)). RESULTS: The sample included 285 breast cancer patients (mean age: 53 years). The median OTT was 38 days (IQR: 17-48 days), with 123 (43.2%) patients having prolonged OTT. The completion rate was 57.9%. No significant differences in OTT (44.4% vs. 35.7%, p = 0.445) and completion rate (57.2% vs. 61.9%, p = 0.569) were found between the JKN-NON-PBI and JKN-PBI groups, respectively. In all, the data reported 3,022 interrupted days of radiotherapy across a total of 227 patients. The most common reason for radiotherapy interruption was unknown. CONCLUSION: There are problems in timely delivery and low completion rate of radiotherapy among breast cancer patients in Indonesia. There are no significant differences in OTT and completion rate between the insurance schemes.

Parental Acceptance of Human Papillomavirus (HPV) Vaccination in Districts with High Prevalence of Cervical Cancer in West Java, Indonesia.

Background: Cervical cancer is the second-highest cause of death in women with cancer, which is mostly caused by human papillomavirus (HPV) infection, specifically HPV 16 and 18. Next to Pap smear and visual inspection with acetic acid, HPV vaccination is highly recommended to support preventive measures. Objective: This study aimed to determine parental acceptance of HPV vaccination in districts with high prevalence of cervical cancer and different levels of household income in West Java, Indonesia by taking several factors into account. Methods: A questionnaire was delivered to 286 parents who met the major inclusion criteria of having daughters at 5th or 6th grade of elementary schools in three selected districts: Bandung, Purwakarta and Karawang. In particular, logistic regression analysis was applied to investigate the correlation of acceptance towards HPV vaccination with sociodemographic factors. Results: Respondents in Bandung, Purwakarta and Karawang were willing to pay for HPV vaccine at a price range of US$ 1.38-20.69, US$ 0.07-34.48, and US$ 1.38-6.90, respectively. In addition, respondents' spouse was the key person influencing their decision to vaccinate their children. Conclusion: Education level and health beliefs toward cervical cancer have significant correlation (p-value <0.05) with acceptance towards HPV vaccination.

Investigating the Relationship between Knowledge and Hepatotoxic Effects with Medication Adherence of TB Patients in Banyumas Regency, Indonesia.

Tuberculosis (TB) still remains the burden in Indonesia. One of the factors that may influence the treatment success of TB is patient's adherence. However, the hepatotoxicity of the TB medicine may decrease the patient's adherence. Our study's aim is to investigate the relationship between the patient's knowledge and the hepatotoxicity with medication adherence of TB patients in Banyumas Regency. This study was conducted at one Community Lung Health Center and two hospitals in Banyumas Regency, Purwokerto, Center of Java, Indonesia. The respondents were 91 TB patients with hepatotoxicity characterized by an increased aspartate transaminase (AST) and alanine aminotransferase (ALT). The level of the patients' knowledge about the hepatotoxicity effect was determined using a questionnaire. The patients' adherence was determined using the Medication Adherence Rating Scale -5 (MARS) questionnaire and pill count methods. Most of the patients were male (53.8%), the age was in the range of 18-29 years old (3.5%), they have no smoking history (59.3%), and their last education majorly was senior high school (46.2%). Most TB patients had poor knowledge (47.3%) and the hepatotoxic effect often appeared in grade 1 (61.5%). The TB patients with a good and moderate level of knowledge were 17.6% and 35.2%, respectively. The TB patients with moderate and severe hepatotoxicity were 39.4% and 1.1%, respectively. The measurement of the level of respondents' adherence using MARS-5 showed that 51.6% of patients had good adherence. We determined the rest of the drug-using pill count method, which resulted in 62.6% of patients adhering to taking antituberculosis drugs. TB patients with a sufficient knowledge and those with mild hepatotoxicity show the higher adherence (p < 0.001). There is a significant relationship between a high level of the patient's knowledge about hepatotoxicity effect, less severity of the hepatotoxic effect, and increased patient adherence in taking the medication.

Economic Evaluations of HPV Vaccination in Targeted Regions of Low- and Middle-Income Countries: A Systematic Review of Modelling Studies.

Background: In countries with limited resources, a targeted HPV vaccination strategy by focusing in selected regions is preferable to be implemented than a nationwide vaccination strategy. Objective: This study aimed to review articles on economic evaluations of HPV vaccination in countries over the world that applied targeted vaccination strategies. Methods: Approximately 1769 articles were obtained from two databases (1242 and 527 articles from PubMed and ProQuest, respectively). The inclusion criteria in this systematic review were studies about full economic evaluations of HPV vaccination in targeted area or sub-national level and written in English. Full-text screening was applied to evaluate the eligibility. Final articles obtained were referred to the Consolidated Health Economic Evaluation Reporting Standard (CHEERS) checklist. Finally, we included only 4 articles that met all inclusion and exclusion criteria. Results: Included studies in this review focused in different targeted regions, such as Punjab State in India, Vientiane in Lao PDR, Southern Vietnam in Vietnam, and Brazilian Amazon in Brazil. From 24 criteria in the CHEERS checklist, all included studies could meet 21 criteria (87.5%). All included studies in this review applied modeling approaches, which can estimate the number of cases and treatment costs averted. Applying various settings, the results of this study showed that HPV vaccination could potentially reduce the number of cervical cancer cases by 20-72%. Taking cervical cancer screening into account, this study showed that targeted HPV vaccination was cost-effective or even cost-saving. Conclusion: Implementation of HPV vaccination in sub-national level as the initial step before nationwide vaccination is more favorable to be implemented in countries with limited budget.

The willingness for cervical cancer screening among sexually active women in Indonesia: Lesson learned from two districts.

OBJECTIVE: To determine the factors that affect women's willingness at childbearing age to detect/screen for cervical cancer. METHODS: A cross-sectional study was carried out on sexually active women, aged 30-50 years residing in Banyumas and Gunung Kidul Districts, Indonesia. There were 600 respondents. This study focused on the impact of knowledge, access to health information, and support of their husband on the willingness to undergo early detection of cervical cancer. RESULTS: This study revealed that there was a statistically significant difference (P = 0.000) between the women who were willing and unwilling to do the screening in terms of higher knowledge (64.67% and 36.21%), obtained access to the information (80.43% and 54.74%), and supported by their husband (63.59% and 29.31%). This study also discovered that the willingness to be screened was significantly affected by spousal support (odds ratio [OR] 4.19, 95% confidence interval [CI] 2.81-6.27). Other factors, such as education level (OR 2.94, 95% CI 1.20-6.63), knowledge (OR 2.29, 95% CI 1.52-3.44), and access to information (OR 2.08, 95% CI 1.34-3.24), were also important drivers. CONCLUSION: To improve the coverage of cervical screening, several aspects could be treated, including education, knowledge, access to information, and spousal support.

Cost-Effectiveness Analysis of BCG Vaccination against Tuberculosis in Indonesia: A Model-Based Study.

Bacillus Calmette-Guerin (BCG), the only available vaccine for tuberculosis (TB), has been applied for decades. The Indonesian government recently introduced a national TB disease control programme that includes several action plans, notably enhanced vaccination coverage, which can be strengthened through underpinning its favourable cost-effectiveness. We designed a Markov model to assess the cost-effectiveness of Indonesia's current BCG vaccination programme. Incremental cost-effectiveness ratios (ICERs) were evaluated from the perspectives of both society and healthcare. The robustness of the analysis was confirmed through univariate and probabilistic sensitivity analysis (PSA). Using epidemiological data compiled for Indonesia, BCG vaccination at a price US$14 was estimated to be a cost-effective strategy in controlling TB disease. From societal and healthcare perspectives, ICERs were US$104 and US$112 per quality-adjusted life years (QALYs), respectively. The results were robust for variations of most variables in the univariate analysis. Notably, the vaccine's effectiveness regarding disease protection, vaccination costs, and case detection rates were key drivers for cost-effectiveness. The PSA results indicated that vaccination was cost-effective even at US$175 threshold in 95% of cases, approximating the monthly GDP per capita. Our findings suggest that this strategy was highly cost-effective and merits prioritization and extension within the national TB programme. Our results may be relevant for other high endemic low- and middle-income countries.

Cervical cancer prevention in Indonesia: An updated clinical impact, cost-effectiveness and budget impact analysis.

INTRODUCTION: The clinical and economic impact of cervical cancer consistently become a serious burden for all countries, including Indonesia. The implementation of HPV vaccination policy for a big country such as Indonesia requires a strong commitment from several decision-makers. The aim of this study was to provide a comprehensive description on cost-effectiveness and the budget-impact of HPV vaccination policy in Indonesia. METHOD: A cohort Markov model was used to evaluate the cost and the clinical impact of HPV vaccination for 10 years old girls in Indonesia. The researchers consider two doses of all three available HPV vaccines adjusted with the HPV infection profilewith 95% vaccination coverage to estimate the national cervical cancer incidence and mortality. The Budget impact analysis explores three different scenarios covering (1) Two districts per year expansion, (2) oneprovince per year expansion and (3) achieving the National Immunization Program in 2024. RESULTS: Upon fully vaccinating almost 2.3 million 10-year-old girls, 34,723; 43,414; and 51,522 cervical cancer cases were prevented by Quadrivalent, Bivalent and Nonavalent vaccines, consecutively. Furthermore, the highest (591 cases) and lowest (399 cases) mortality were prevented by Nonavalent and Quadrivalent vaccines, respectively. Most of the vaccines were considerably cost-effective and only the Bivalent vaccine with the GAVI/UNICEF price which will be considered a cost-saving strategy.To provide national coverage of HPV vaccination in Indonesia, the government has to provide an annual budget of about US$49 million and US$22 million using the government contract price and GAVI/UNICEF price, respectively. CONCLUSION: HPV vaccination shows a cost-effective strategy and the budget required to provide this policy is considerably affordable for Indonesia.

Prevention of Surgical Site Infections: A Systematic Review of Cost Analyses in the Use of Prophylactic Antibiotics.

Introduction: The preoperative phase is an important period in which to prevent surgical site infections (SSIs). Prophylactic antibiotic use helps to reduce SSI rates, leading to reductions in hospitalization time and cost. In clinical practice, besides effectiveness and safety, the selection of prophylactic antibiotic agents should also consider the evidence with regard to costs and microbiological results. This review assessed the current research related to the use of antibiotics for SSI prophylaxis from an economic perspective and the underlying epidemiology of microbiological findings. Methods: A literature search was carried out through PubMed and Embase databases from 1 January 2006 to 31 August 2017. The relevant studies which reported the use of prophylactic antibiotics, SSI rates, and costs were included for analysis. The causing pathogens for SSIs were categorized by sites of the surgery. The quality of reporting on each included study was assessed with the "Consensus on Health Economic Criteria" (CHEC). Results: We identified 20 eligible full-text studies that met our inclusion criteria, which were subsequently assessed, studies had in a reporting quality scored on the CHEC list averaging 13.03 (8-18.5). Of the included studies, 14 were trial-based studies, and the others were model-based studies. The SSI rates ranged from 0 to 71.1% with costs amounting to US$480-22,130. Twenty-four bacteria were identified as causative agents of SSIs. Gram negatives were the dominant causes of SSIs especially in general surgery, neurosurgery, cardiothoracic surgery, and obstetric cesarean sections. Conclusions: Varying results were reported in the studies reviewed. Yet, information from both trial-based and model-based costing studies could be considered in the clinical implementation of proper and efficient use of prophylactic antibiotics to prevent SSIs and antimicrobial resistance.

The Development of Quality of Life Questionnaire for Indonesian Breast Cancer Patients: INA-BCHRQoL

Introduction: The breast cancer related incidence and mortality rate in Indonesia are included in the top 10 and top 5 highest in the world. A country-specific Health Related Quality of Life measurement tool is required to help clinician observe and improve the management of the disease. Methods: We developed the questionnaire, namely Indonesian Breast Cancer Health Related Quality of Life (INA-BCHRQoL) by incorporating not only the generic variables such as physical, psychological, and social; but also spiritual variable which is suitable for Indonesian population. The questionnaire was validated to the same population using the value of corrected item-total correlation and the value of Cronbach Alpha. Results: Fourty three questions were considerably valid and reliable on evaluating the HRQoL of early state of breast cancer patients in Indonesia as the value of Cronbach Alpha for physical, cognitive, social and spiritual domain were higher than 0.8 and the corrected item-total correlation were also higher than 0.3. Each domain of the questionnaire was not influenced by the treatment options. Twenty four early stage breast cancer (10 FAC based chemotherapy and 14 Taxan based chemotherapy) were enrolled in the main study and the score of HRQOL obtained from INA-BCHRQoL were considerably high. Conclussion: The INA-BCHRQoL questionnaire can be implemented as a valid and reliable tool to assess quality of life in early stage breast cancer patients in Indonesia.

Cost Effectiveness of Human Papillomavirus Vaccination for Men Who have Sex with Men; Reviewing the Available Evidence.

BACKGROUND: Men who have sex with men require special attention for human papillomavirus vaccination given elevated infection risks and the development of, in particular, anal cancer. OBJECTIVE: Our purpose was to review the cost effectiveness of human papillomavirus vaccination for both currently vaccine-eligible and non-eligible individuals, particularly the men-who-have-sex-with-men population, and synthesize the available evidence. METHODS: We systematically searched for published articles in two main databases (PubMed and EMBASE). Screening and data extraction were performed by two independent reviewers. The risk of bias was assessed using a validated instrument (Bias in Economic Evaluation, ECOBIAS). Methodological aspects, study results, and sensitivity analyses were extracted and synthesized to generate a consistent overview of the cost effectiveness of human papillomavirus vaccination in the men-who-have-sex-with-men population. RESULTS: From 770 identified articles, four met the inclusion criteria. Across the studies, human papillomavirus vaccination showed incremental cost-effectiveness ratios ranging from dominant to US$96,146 and US$14,000 to US$18,200 for tertiary prevention and primary prevention, respectively. The incremental cost-effectiveness ratio seemed most sensitive to vaccine efficacy, vaccine costs, and the incidence of anal cancer in the selected target populations. CONCLUSION: This review presents the human papillomavirus vaccine, both as a primary and adjuvant (tertiary) vaccination, as a potentially cost-effective strategy for preventing mainly-but not limited to only-anal cancer in men-who-have-sex-with-men populations.

Health-Related Quality of Life of Patients with HPV-Related Cancers in Indonesia.

BACKGROUND: Human papillomavirus (HPV)-related cancers are a serious concern in developing countries. Valid estimates of a country-specific health-related quality of life (HRQOL) for patients with HPV-related cancers provide a substantial tool in determining the burden of the disease. OBJECTIVES: To investigate the HRQOL of patients with HPV-related cancers in Indonesia. METHODS: The HRQOL of patients with HPV-related cancers (cervical, uterine, nasopharyngeal, head and neck, and anogenital cancer) was assessed using the EuroQol five-dimensional questionnaire (EQ-5D). Validity and reliability were assessed by means of construct validity and test-retest reliability methods, respectively. Subsequently, the EQ-5D utility index was calculated using the Thailand value set. RESULTS: The EQ-5D came out as a valid and reliable questionnaire for measuring the HRQOL of patients with HPV-related cancers in Indonesia. From a total of 520 patients diagnosed with HPV-related cancers, 404 patients were excluded because of not fulfilling the inclusion criteria, and so 116 patients finally participated in the study. The mean age of the patients was 47.5 ± 12.03 years. Most of the patients were women (56.0%) and married (97.4%), and less than half of them had finished high school (32.7%). Moreover, the proportions of nasopharyngeal, cervical, head and neck, anogenital, and uterine cancers in the study population were 29.3%, 24.6%, 22.4%, 14.2%, and 9.5%, respectively. The average HRQOL of the patients with HPV-related cancers was 0.69 ± 0.10, with the highest and lowest estimates applying to uterine cancer (0.84 ± 0.29) and head and neck cancer (0.58 ± 0.33), respectively. CONCLUSIONS: The HRQOL of patients with HPV-related cancers was found to be reduced to a certain extent in our study for Indonesia.

The health-economic studies of HPV vaccination in Southeast Asian countries: a systematic review.

INTRODUCTION: The cervical cancer-related burden is an important problem in Southeast Asian (SEA) countries. However, only 3 out of 11 countries implement the comprehensive prevention program. Areas covered: This is a retrospective review from all relevant studies until 2015 from two main databases, MEDLINE/Pubmed and Embase in order to provide an evidence on the health economics of HPV vaccination in the region. Expert commentary: The implementation of HPV vaccination will generate substantial health and economic benefit in SEA countries since the number of cervical cancer cases in this region are generally high. Therefore, a clear recommendation on how HPV vaccination should be implemented in a country, for example on how many doses will be used, how much cost is required or is it a school based- or clinical based-delivery, is critically required.

Immunogenicity and safety of human papillomavirus (HPV) vaccination in Asian populations from six countries: a meta-analysis.

Cervical cancer is a serious public-health problem in Asian countries. Since human papillomavirus (HPV) infection is the main risk factor for cervical cancer, HPV vaccination is considered a promising strategy to prevent cervical cancer. However, comprehensive immunogenicity and safety information for Asian populations is lacking. We searched four electronic databases including PubMed, EMBASE, Cochrane Library, and clinicaltrials.gov. We reviewed selected manuscripts and extracted the pooled relative risk (RR) from immunogenicity and safety information on HPV vaccination among women in Asian countries. We identified two quadrivalent-vaccine studies and eight bivalent-vaccine studies conducted in Asian countries. Analysis across these studies suggested that the HPV vaccines significantly enhanced HPV16- and HPV18-specific antibody among both uninfected (RR 85.69; 95% confidence interval (CI) 31.51-233.04 and 62.77; 95% CI 37.4-105.51) and infected individuals (RR 8.60; 95% CI 6.95-10.64 and RR 8.13; 95% CI 5.96-11.11). Furthermore, HPV vaccination among Asian populations has a favorable safety profile, with only slightly higher risks of local (RR: 1.89; 95% CI 1.65-2.17) and systemic (RR: 1.33; 95% CI 1.18-1.50) adverse events in vaccinated individuals compared with controls. For Asian populations, HPV vaccines enhance the level of HPV16- and HPV18-specific antibodies for both uninfected and infected individuals. Also, the risk of adverse events related to vaccination are acceptable. More data are needed to establish vaccine efficacy with regard to prevention of HPV infection and further outcomes including cervical intraepithelial neoplasia (CIN) and cervical cancer.
