Pharmacoeconomic issues in stem cell mobilization.

Background: recently, stem cell mobilization has made dramatic progress, that ended up in an increasing number of aphereses at target for autologous peripheral stem cell transplantation (ASCT). The aim of this research is investigating the cost-effectiveness of stem cell mobilization.

Methods: a narrative review of the literature was carried out, searching for primary contributions written in English and published during 2000-2023 on cost-effectiveness analysis (CEA) of stem cell mobilization in patients entitled to ASCT. The PubMed database was searched with the following sets of keywords: cost-effectiveness AND apheresis AND myeloma (PubMed_1); cost-effectiveness AND stem cell mobilization (PubMed_2). Articles included in the analysis were assessed via two different checklists.

Results: sixty-six entries were retrieved. Five out of 66 (PubMed_1: 4 out 17; PubMed_2: 1 out of 49), 4 CEAs and 1 cost-utility analysis (CUA) fit the research goal. Four out of 5 contributions proved to be in line with most of the items included in the two assessment grids. However, the most relevant missing features in some of the included contributions were: study perspective, healthcare resources valuation, and sensitivity analyses.

Discussion: most of the articles included in this research show that chemotherapy-free stem cell mobilization is cost-effective according to different standpoints. Future health economic research on this topic should establish local threshold values for incremental apheresis at target and explore the heterogeneity of CEA (and CUA) to determine oncohaematological diseases and patient categories for which chemotherapy-free stem cell mobilization is cost-effective in different healthcare systems, given local budget constraints.
