Abstract
Background: Clinical guidelines recommend surgery for early-stage breast cancer in operable patients; however, primary endocrine therapy (PET) is often used in older women aged ≥ 70. This study aimed to estimate the cost-effectiveness and value of implementation of surgery plus adjuvant endocrine therapy (ET) compared with PET for older women with early breast cancer who are fit for surgery.
Method: A partitioned survival analysis model was developed using effectiveness data from the published literature (time horizon: lifetime). Health outcomes were measured as quality-adjusted life years (QALYs; EQ-5D-3L UK tariff). Direct costs were estimated from the perspective of NHS England (discount rate: 3.5%). Probabilistic sensitivity analysis and value of implementation analysis were conducted using a cost-effectiveness threshold of £20,000-£30,000 per QALY gained.
Results: Surgery + ET resulted in higher QALYs (4.57) compared to PET (3.87) and higher costs (£10,628 vs. £6,102). The incremental cost-effectiveness ratio (ICER) was £6,412.62 per QALY gained, indicating that surgery + ET is cost-effective compared to PET. The value of implementation analysis showed that imperfect implementation of surgery + ET resulted in a loss of 0.12 QALYs per patient, equating to 9,267 QALYs at the population level.
Conclusion: Surgery with adjuvant ET is a clinically effective and cost-effective strategy compared with PET for older women with ER + operable early-stage breast cancer. Strengthening adherence to national guidelines will improve population health outcomes and healthcare resource use. Future economic evaluations should focus on the value of management strategies for older patients unfit for surgery due to frailty or comorbidities.
期刊介绍：
Health Economics Review is an international high-quality journal covering all fields of Health Economics. A broad range of theoretical contributions, empirical studies and analyses of health policy with a health economic focus will be considered for publication. Its scope includes macro- and microeconomics of health care financing, health insurance and reimbursement as well as health economic evaluation, health services research and health policy analysis. Further research topics are the individual and institutional aspects of health care management and the growing importance of health care in developing countries.
