Systematic Literature Review of Economic Evaluations, Costs/Resource Use, and Quality of Life in Patients with Mantle Cell Lymphoma

BACKGROUND: Mantle cell lymphoma (MCL) is a rare and aggressive subtype of non-Hodgkin’s lymphoma. While treatment of patients with MCL and their outcomes are previously published, the availability of heath economics evidence is unclear. OBJECTIVE: The aim of this paper was to conduct a comprehensive review of studies relating to economic evaluations, costs and resource use, and health-related quality of life (HRQoL) in patients with MCL. METHODS: Search strategies were designed to capture studies reporting economic or HRQoL outcomes published in the previous 11 years (2007–2018). The following electronic databases were searched: MEDLINE, Embase, NHS Economic Evaluation Database (NHS EED), and EconLit. In addition, we reviewed congress abstracts presented over the previous 2 years (2015 and 2016; where 2017 proceedings had occurred, these were searched instead of 2015). Publications were screened in duplicate by two reviewers and supplementary searches were carried out on health technology assessment websites. Searches were first conducted in October 2017 and updated in March 2018. FINDINGS: The systematic literature review identified 11 economic evaluations (in 16 publications), seven studies reporting data relating to costs or resource use, and five relating to HRQoL. Four economic evaluations presented results for patients with MCL modelled in the first-line setting, while seven modelled patients in the relapsed/refractory setting. The majority of economic evaluations were conducted using a Markov model with three to five health states. Seven studies assessed resource use and reported adverse events as key drivers of increased costs and resource use. Across the five studies reporting HRQoL, disparate measures were used. Two studies reported improvement in Functional Assessment of Cancer Therapy-Lymphoma (FACT-Lym) total scores following treatment and found that clinical response to treatment was associated with improvement in overall HRQoL. CONCLUSIONS AND RELEVANCE: The published economic and HRQoL evidence in MCL, although scarce, reveals that the economic and HRQoL burden associated with MCL is substantial. In highlighting this evidence, this analysis underlines a critical unmet need for more effective treatments with improved outcomes in MCL.
