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.

Abstract
BACKGROUND There has been a lot of debate on how to 'generalise' or 'translate' findings of economic evaluation (EE) or health technology assessment (HTA) to other country contexts. Researchers have used various adaptive HTA (aHTA) methods like model-adaptation, price-benchmarking, scorecard-approach, etc., for transferring evidence from one country to other. This study was undertaken to assess the degree of accuracy in results generated from aHTA approaches specifically for EE. METHODS By applying selected aHTA approaches, we adapted findings of globally published EE to Indian context. The first-step required identifying two interventions for which Indian EE (referred to as the 'Indian reference study') has been conducted. The next-step involved identification of globally published EE. The third-step required undertaking quality and transferability check. In the fourth step, outcomes of EE meeting transferability standards, were adapted using selected aHTA approaches. Lastly, adapted results were compared with findings of the Indian reference study. RESULTS The adapted cost estimates varied considerably, while adapted quality-adjusted life-years did not differ much, when matched with the Indian reference study. For intervention I (trastuzumab), adapted absolute costs were 11 and 6 times higher than the costs reported in the Indian reference study for control and intervention arms, respectively. Likewise, adapted incremental cost and incremental cost-effectiveness ratio (ICER) were around 3.5-8 times higher than the values reported in the Indian reference study. For intervention II (intensity-modulated radiation therapy), adapted absolute cost was 35% and 12% lower for the comparator and intervention arms, respectively, than the values reported in the Indian reference study. The mean incremental cost and ICER were 2.5 times and 1.5 times higher, respectively, than the Indian reference study values. CONCLUSION We conclude that findings from aHTA methods should be interpreted with caution. There is a need to develop more robust aHTA approaches for cost adjustment. aHTA may be used for 'topic prioritisation' within the overall HTA process, whereby interventions which are highly cost-ineffective, can be directly ruled out, thus saving time and resources for conducting full HTA for interventions that are not well studied or where evidence is inconclusive.

Abstract
The incidence of breast cancer is increasing in low- and middle-income countries, including Thailand. However, its molecular immunohistochemical (M-IHC) subtypes have not been summarized in a population-based cancer registry. Thus, we aimed to estimate the breast cancer incidence and trends based on the hormone receptor and human epidermal growth factor receptor 2 (HER2) status. This cross-sectional study included 2,883 women diagnosed with primary invasive breast cancer between 2009 and 2018 from the Songkhla Cancer Registry. After imputing the missing values of estrogen receptor (ER), progesterone receptor (PR), and HER2 status, the cases were classified into four subtypes: HR+/HER2-, HR+/HER2+, HR-/HER2-, and HR-/HER2+. The age-specific incidence rate of 5-year age groups and age-standardized incidence rate (ASR) were calculated. An age-period-cohort (APC) model was used to describe the effects of age, birth cohort, and period of diagnosis. Finally, the incidence trends were extrapolated to 2030 based on the APC and joinpoint models. The results showed, HR+/HER2- had the highest ASR in breast cancer. The incidence trends of HR+/HER2- and HR+/HER2+ increased with an annual percent change of 5.4% (95%CI: 2.5% to 8.3%) and 10.1% (95%CI: 4.9% to 15.5%), respectively. The rate ratio was high in the younger generation and recent period of diagnosis. The joinpoint and APC model projections showed that the ASR of HR+/HER2- would reach 30.0 and 29.2 cases per 100,000 women, while ASR of the HR+/HER2+ would reach 8.8 and 10.4 cases per 100,000 women in 2030. On the other hand, the incidence trends of the HR-/HER2- and HR-/HER2+ subtypes were stable. The rising trends of HR-positive and a part of HER2-positive breast cancer forecast a dynamicity of the future health care budgeting, resource allocation, and provision of facilities.

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.

Abstract
INTRODUCTION As the availability of new economic evaluations (EE) on adjuvant trastuzumab therapy for early-stage breast cancer (EBC) with HER2-positive since last search and other EEs missed warrant a more extensive review, this study aimed to systematically review EEs of adjuvant trastuzumab compared with chemotherapy alone for HER2-positive EBC. AREA COVERED The search was performed in February 2019 using MEDLINE and Scopus. Reviewers independently selected studies based on eligibility criteria, extracted data, assessed quality of reporting, and appraised quality of data sources. EXPERT OPINION 22 studies were included which were from high-income (HICs) and upper-middle income countries (UMICs). Incremental cost-effectiveness ratios (ICERs) from HICs were within their cost-effectiveness thresholds and ranged from 6,018 to 78,929 USD per quality-adjusted life year (QALY) gained. ICERs from UMICs mostly exceeded their thresholds ranging from 3,526 to 174,901 USD per QALY gained. Evidence shows cost-effectiveness of trastuzumab for HER2-positive EBC in HICs. There were no methodological variations. The extent and adequacy of reporting were high. The quality of data sources was moderate to high. The quality of future EEs can be improved by enhancing the reporting quality, by using context-based data and real-world efficacy data, which would impact cost-effectiveness.

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.

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.
