Cost-Effectiveness of Drug Treatments for Advanced Melanoma: A Systematic Literature Review

Abstract

Background

Until recently, advanced melanoma (unresectable and metastatic) has had a poor prognosis and has been treated with chemotherapy. The introduction of new treatments (BRAF and MEK inhibitors and immunotherapy) has improved overall survival and progression-free survival of some patients.

Objective

The objective of this study was to review the published evidence on the cost-effectiveness of pharmacological treatments for advanced melanoma.

Methods

A systematic literature search was conducted, without date or language restrictions, in PubMed, EMBASE, Scopus, the Cochrane Library, the UK National Institute for Health and Care Excellence databases and the Health Technology Assessment journal. Internet searches were also made to identify possible grey literature. Main study characteristics, methods and outcomes were extracted and critically assessed. The quality of health economic studies was assessed by the Quality Assessment of Economic Evaluation in Health Care checklist.

Results

The search identified nine full-text pharmacoeconomic analyses of advanced melanoma treatments. According to the economic analyses published in the articles, the new treatments have been shown to be more effective (with more life-years and quality-adjusted life-years) than chemotherapy, although generally the cost per quality-adjusted life-year gained was above the commonly accepted threshold. Because of the variability of the available analyses comparing the new treatments, we cannot determine which treatment is the most cost-effective.

Conclusions

From the available data, it cannot be concluded that the new drugs (BRAF and MEK inhibitors and immunotherapy) are cost effective compared with chemotherapy or which is the most cost-effective new treatment.
