The cost-effectiveness of neoadjuvant chemotherapy in women with locally advanced breast cancer: Adriamycin and cyclophosphamide in comparison with paclitaxel and gemcitabine

A systematic literature review on direct and indirect costs of triple-negative breast cancer

BACKGROUND

Triple-negative breast cancer (TNBC) is an aggressive and therapy-resistant form of breast cancer with a significant economic burden on patients and healthcare systems. Therefore, we completed a systematic review to classify and synthesize the literature on the direct and indirect costs of TNBC.

METHODS

Databases including ISI Web of Science, Scopus, PubMed, and Google Scholar were searched for all related articles assessing the economic burden of TNBC from 2010 until December 2022. The quality and eligibility assessments were done accordingly. We adjusted all costs to January 2023 $US.

RESULTS

From 881 records, 15 studies were eligible. We found that studies are widely disparate in the timetable, study design, patient populations, and cost components assessed. The annual per-patient direct costs of metastatic TNBC (mTNBC) were about $24,288 to $316,800. For early TNCB patients (eTNBC) this was about $21,120 to $105,600. Cancer management anticancer therapy costs account for the majority of direct costs. Along with an increase in cancer stage and line of therapy, healthcare costs were increased. Moreover, the indirect costs of patients with mTNBC and eTNBC were about $1060.875 and about $186,535 for each patient respectively.

CONCLUSION

The results showed that the direct and indirect costs of TNBC, mainly those of mTNBC, were substantial, suggesting attention to medical progress in cancer prognosis and therapy approaches.

The cost effectiveness of intensity-modulated radiation therapy and three-dimensional conformal radiotherapy in the treatment of head and neck cancers

PURPOSE

Intensity-modulated radiotherapy is developed as a replacement for 3-dimensional conformal radiation therapy. Considering the difference in costs and effectiveness of these interventions, the aim of this study was to compare the cost effectiveness of intensity-modulated radiation therapy and three-dimensional conformal radiotherapy in the treatment of head and neck cancer in east of Iran.

METHODS

A Markov model including six states based on xerostomia and dysphagia was developed to estimate the incremental cost effectiveness ratio from the perspective of societal. Cost and quality of life data were collected from 97 respondents via a checklist and EuroQol-5Dimension questionnaire. The robustness of results was examined by deterministic and probabilistic sensitivity analysis. All analysis were conducted with Treeage software.

RESULTS

The results of this study showed that the cost and quality adjusted life years for 3-dimensional conformal radiation therapy were 9209.76 and 3.63 respectively. However, the cost and quality adjusted life years for intensity-modulated radiotherapy were 12562.90 and 3.17 respectively. Therefore, 3-dimensional conformal radiation therapy produced 0.45 more quality adjusted life years than intensity-modulated radiotherapy and saved $3353. According to the incremental cost effectiveness ratio, 3-dimensional conformal radiation therapy as compared to intensity-modulated radiotherapy saved $7367.27 per quality adjusted life years. These results confirmed by sensitivity analysis.

CONCLUSION

This study concluded that in the treatment of head and neck cancer, the 3-dimensional conformal radiation therapy method appears to be cost-effective when compared with intensity-modulated radiotherapy.

Economic Evaluations of Breast Cancer Care in Low- and Middle-Income Countries: A Scoping Review

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.

Cost of breast cancer care in low- and middle-income countries: a scoping review protocol

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.
