Abstract

Background: Approximately 23% of myeloma patients have cytogenetic abnormalities which confer a significantly poorer prognosis, and therefore they are defined as “high-risk myeloma” (HRC+) patients.

Objective: To estimate the economic impact of a large-scale use of the fluorescence in situ hybridization (FISH) test for the identification of HRC+ patients.

Methods: The comparison between the total costs of two scenarios, the first one where patients are not tested for cytogenetic abnormalities, the second one where FISH test is used to identify HRC+ patients and to treat them with the most appropriate therapies, was conducted. The Italian National Healthcare Service (NHS) perspective was adopted. The cost of each treatment was estimated by multiplying Italian unit ex-factory prices by median progression-free survival (PFS). For each scenario, the cost per month of PFS gained was calculated. Sensitivity analysis was conducted to evaluate the impact on the results.

Results: N = 777 patients are expected to be HRC+ in Italy. If they were all identified through FISH test and treated with the most appropriate therapies, this would result into savings of € 552,000 and a PFS gain of 419 months, compared with a scenario with no identification. The cost per patient per month of PFS gained is lower in the scenario where FISH test was available (€ 9,921 vs € 10,229 in the scenario without testing). Sensitivity analyses confirmed the robustness of the base case results.

Conclusions: A larger adoption of FISH test to identify HRC+ patients is expected to improve clinical outcomes in relapsed refractory multiple myeloma.
