Abstract
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.

Khoirunnisa SM, Suryanegara FDA, Setiawan D, Postma MJ, de Jong LA. Economic evaluation of trastuzumab in HER2-positive early breast cancer in Indonesia: A cost-effectiveness analysis. PLoS One 2024; 19:e0304483. [PMID: 38787899 PMCID: PMC11125485 DOI: 10.1371/journal.pone.0304483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 05/13/2024] [Indexed: 05/26/2024] Open
Abstract
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.

Nguyen AQ, Tran OTM, Nguyen PK, Nguyen HT. Cost-effectiveness of one-year adjuvant trastuzumab therapy in treatment for early-stage breast cancer patients with HER2+ in Vietnam. PLoS One 2024; 19:e0300474. [PMID: 38489305 PMCID: PMC10942069 DOI: 10.1371/journal.pone.0300474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Accepted: 02/19/2024] [Indexed: 03/17/2024] Open
Abstract
BACKGROUND In Vietnam, trastuzumab is included in social health insurance's benefits package with a reimbursement rate of 60%, but policymakers have been concerned about its cost-effectiveness. The research aims to evaluate the cost-effectiveness of one-year adjuvant trastuzumab therapy for early-stage breast cancer patients with human epidermal growth receptor 2 (HER2+) from a societal perspective. METHOD A Markov model was developed and validated to estimate the lifetime cost and effectiveness (using life year and quality-adjusted life year) of one-year adjuvant trastuzumab therapy compared to chemotherapy (using paclitaxel) alone. Treatment efficacy and transition probabilities were estimated based on published trials (i.e., N9831, NSABP B-31, HERA, and BCIRG 006). Local cost and utility data were employed to capture the Vietnam context. One-way sensitivity analysis, probabilistic sensitivity analysis, threshold, and scenario analysis were also performed. RESULTS One-year adjuvant trastuzumab therapy combined with chemotherapy compared to chemotherapy alone yielded an additional cost of 888,453,971VND (39,062 US$) with an additional 3.09 LYs and 1.61 QALYs, resulting in an ICER of 287,390,682 VND (12,635 US$) per LY gained, or 519,616,972 VND (22,845 US$) per QALY gained. The ICER exceeds the cost-effective threshold of 1- and 3-time GDP per capita by 6.3 and 2.1 times. The probabilistic sensitivity analysis shows similar results. According to one-way sensitivity analysis, ICERs were driven mainly by transition probabilities and trastuzumab price. One-year adjuvant trastuzumab therapy would be cost-effective at the 3-time GDP per capita threshold if the cost of Herceptin 150mg and 450mg vials were reduced by 56% and 54%, correspondingly. CONCLUSION In Vietnam, one-year adjuvant trastuzumab therapy for early-stage breast cancer with HER2+ is not cost-effective. The research provided reliable and updated evidence to support policymakers in revising the health insurance benefit package. The policymakers should consider the options to reduce the cost of trastuzumab (e.g., regarding the use of trastuzumab biosimilars, price negotiation options, and options of optimizing the use of Herceptin vials among concurrent hospitalized breast cancer patients).

Abstract
BACKGROUND Understanding the cost of delivering breast cancer (BC) care in low- and middle-income countries (LMICs) is critical to guide effective care delivery strategies. This scoping review summarizes the scope of literature on the costs of BC care in LMICs and characterizes the methodological approaches of these economic evaluations. MATERIALS AND METHODS A systematic literature search was performed in five databases and gray literature up to March 2020. Studies were screened to identify original articles that included a cost outcome for BC diagnosis or treatment in an LMIC. Two independent reviewers assessed articles for eligibility. Data related to study characteristics and methodology were extracted. Study quality was assessed using the Drummond et al. checklist. RESULTS Ninety-one articles across 38 countries were included. The majority (73%) of studies were published between 2013 and 2020. Low-income countries (2%) and countries in Sub-Saharan Africa (9%) were grossly underrepresented. The majority of studies (60%) used a health care system perspective. Time horizon was not reported in 30 studies (33%). Of the 33 studies that estimated the cost of multiple steps in the BC care pathway, the majority (73%) were of high quality, but studies varied in their inclusion of nonmedical direct and indirect costs. CONCLUSION There has been substantial growth in the number of BC economic evaluations in LMICs in the past decade, but there remain limited data from low-income countries, especially those in Sub-Saharan Africa. BC economic evaluations should be prioritized in these countries. Use of existing frameworks for economic evaluations may help achieve comparable, transparent costing analyses. IMPLICATIONS FOR PRACTICE There has been substantial growth in the number of breast cancer economic evaluations in low- and middle-income countries (LMICs) in the past decade, but there remain limited data from low-income countries. Breast cancer economic evaluations should be prioritized in low-income countries and in Sub-Saharan Africa. Researchers should strive to use and report a costing perspective and time horizon that captures all costs relevant to the study objective, including those such as direct nonmedical and indirect costs. Use of existing frameworks for economic evaluations in LMICs may help achieve comparable, transparent costing analyses in order to guide breast cancer control strategies.

The global landscape of availability, accessibility and affordability of essential diagnostics and therapeutics for the management of HER2-positive breast cancer: The ONCOLLEGE-001 survey. J Cancer Policy 2021; 28:100285. [PMID: 35559914 DOI: 10.1016/j.jcpo.2021.100285] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 04/01/2021] [Accepted: 04/20/2021] [Indexed: 02/08/2023]
Abstract
AIM OF THE STUDY Barriers in access to essential care are key determinants of disparities in cancer survival. Breast cancer (BC) is the most common cancer and lead cause of mortality among women, 60 % occurring in low- and middle-income countries (LMs). A quarter of BC are characterized by an over-expression of the epidermal growth factor receptor 2 (HER2). Valuable strategies to diagnose and manage patients with HER2-positive BC have been determined and some considered essential health interventions. ONCOLLEGE-001 is a global survey of availability, accessibility, and affordability of essential HER2 diagnostics and therapeutics. METHOD A self-administered questionnaire was shared electronically to oncologists, identified from oncology networks. Data were analyzed using descriptive statistics, per income areas and geographic regions. RESULTS We received 191 responses (84 % response rate). The majority of the responders were from LMs (n = 153) and were physician providers. Immunohistochemistry was the most common HER2 diagnostics available (n = 185). A third of the responders from low/lower-middle and a half of upper-middle income countries had HER2 testing only in the private sector. Trastuzumab was not available for 8 %: when available, 15%-21% reported accessibility only as out-of-pocket expenditure; when not reimbursed, only 10 % of the providers could significantly offer this intervention. Availability of trastuzumab biosimilars was reported in more than a half of the responders (n = 107). CONCLUSION Stark disparities are reported, with high out-of-pocket expenses for HER2 testing and significant financial barriers to access trastuzumab treatments. Policy solutions are urgently warranted for the selection, prioritization, and reimbursement of essential health interventions, to result in improved population health. POLICY SUMMARY STATEMENT: the inclusion of essential services for cancer management should be assured and financed in the benefit packages of healthcare to all. Prioritizing high-value health interventions, including medicines and medical devices, is critical to deliver impactful programs on population health.

Abstract
OBJECTIVE This review will describe the scope of the literature on the cost of breast cancer care in low- and middle-income countries and summate the methodological characteristics and approaches of these economic evaluations. INTRODUCTION In the past decade, there has been global momentum to improve capacity for breast cancer care in low- and middle-income countries, which have higher rates of breast cancer mortality compared to high-income countries. Understanding the cost of delivering breast cancer care in low- and middle-income countries is critical to guide effective cancer care delivery strategies and policy. INCLUSION CRITERIA Studies that estimate the cost of breast cancer diagnosis and treatment in low- and middle-income countries will be included. Studies not available in English will be excluded. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Review guidelines will be utilized. The search strategy has been developed in consultation with a medical librarian and will be carried out on five electronic databases from their inception (MEDLINE, Embase, Web of Science, Global Health, WHO Global Index Medicus) as well as in gray literature sources. Two independent reviewers will review all abstracts and titles in the primary screen and full-text articles in the secondary screen. A third reviewer will adjudicate conflicts. One reviewer will perform data extraction. Study demographics, design, and methodological characteristics (such as costing perspective, time horizon, and included cost categories) will be summarized in narrative and tabular formats. The methodological quality of studies will be evaluated using a validated economic evaluation tool.

Real-World Setting Cost-Effectiveness Analysis Comparing Three Therapeutic Schemes of One-Year Adjuvant Trastuzumab in HER2-Positive Early Breast Cancer from the Cyprus NHS Payer Perspective. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E4339. [PMID: 32560485 PMCID: PMC7344736 DOI: 10.3390/ijerph17124339] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 06/13/2020] [Accepted: 06/15/2020] [Indexed: 12/27/2022]
Abstract
INTRODUCTION This study is one of the first real-world cost-effectiveness analyses of one-year adjuvant trastuzumab used in HER2-positive early female breast cancer in comparison to chemotherapy alone. It is just the second one in Europe, the first one in Cyprus, and the fourth one worldwide ever carried out using real-world data. METHODS Using a Markov model (four health states), a cost-effectiveness analysis was carried out both over 20 years and for a lifetime horizon. The sampling method used in this study was the randomized sampling of 900 women. RESULTS The findings for the 20-year horizon showed that all trastuzumab arms were more cost-effective, with a willingness-to-pay threshold of only €60,000 per quality-adjusted life year (QALY) [incremental cost-effectiveness ratios (ICER): €40,436.10/QALY]. For the lifetime horizon, with thresholds of €20,000, €40,000, and €60,000/QALY, all trastuzumab arms were found to be more cost-effective (ICER: €17,753.85/QALY). Moreover, for the 20-year and the lifetime horizons, with thresholds of €20,000/QALY, €40,000/QALY, and €60,000/QALY, the most cost-effective of the three subgroups (anthracyclines and then trastuzumab, no anthracyclines and then trastuzumab, and anthracyclines, taxanes, and trastuzumab) was that of anthracyclines and then trastuzumab (ICER: €18,301.55/QALY and €8954.97/QALY, respectively). CONCLUSIONS The study revealed that adjuvant trastuzumab for one year in female HER2-positive early breast cancer can be considered cost-effective.
