Abstract
Background: Cyclin-dependent kinase 4/6 (CDK 4/6) inhibitors have emerged as a significant advancement in the treatment of HR+/HER2- metastatic breast cancer (MBC). Despite the clinical efficacy of CDK 4/6 inhibitors in HR+/HER2- metastatic breast cancer, there remains a significant gap in understanding their cost-effectiveness, particularly regarding the long-term economic impact and the key drivers of costs, when used in combination with endocrine therapy. This study aims to systematically review and conduct a meta-analysis of cost-effectiveness studies evaluating CDK4/6 inhibitors in treatment of HR+/HER2- advanced breast cancer and identify key drivers of costs of CDK4/6 inhibitors in combination with endocrine therapy.
Methods: A comprehensive search of PubMed and Embase was conducted to identify peer-reviewed studies from February 2015 to March 2022 reporting cost-effectiveness of CDK4/6 inhibitors in MBC treatment. Incremental net benefits (INBs) were estimated, and meta-analysis was conducted. This review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
Results: We identified 120 articles, of which 18 were eligible for systematic review and 16 for meta-analysis. None of the three CDK4/6 inhibitors had positive INB compared to endocrine/aromatase inhibitors therapy alone. The pooled INB was estimated at -$149,266.87 (95% Confidence Interval (CI) = -$196,961.54, -$101,572.20).
Conclusion: The combination of CDK4/6 inhibitors and letrozole/endocrine therapy for the treatment of postmenopausal patients with advanced HR+/HER2 - MBC was not cost-effective.
期刊介绍：
Current Medical Research and Opinion is a MEDLINE-indexed, peer-reviewed, international journal for the rapid publication of original research on new and existing drugs and therapies, Phase II-IV studies, and post-marketing investigations. Equivalence, safety and efficacy/effectiveness studies are especially encouraged. Preclinical, Phase I, pharmacoeconomic, outcomes and quality of life studies may also be considered if there is clear clinical relevance
