A cost-minimization analysis of a preventive testing strategy for relatives of patients with BRCA mutated ovarian cancer

Purpose: This study aims to estimate the cost-minimization strategy of a preventive testing strategy destined to relatives of patients with BRCA mutated cancer versus a no test strategy in Italia. Methods: A BRCA testing pathway was designed by a panel of experts based on the MSTM Excel (2010) tool; the analysis was carried out considering the perspective of the Italian National Health Service. Two alternatives were considered: 1) preventive BRCA testing for relatives of patients affected by ovarian cancer carrying a BRCA1/BRCA2 mutation; 2) no test. Cost and effectiveness data, derived from literature and published sources validated by a Board of experts, were discounted using a discount factor equal to 3%. Probabilistic sensitivity analysis was performed. Results: Considering an average cost of therapy for breast and ovarian cancer major of €90,000.00 per case, the economic impact related to the preventive testing strategy are equal to –€17,814,767.25. The sensitivity analysis confirms these results in the totality of the simulations performed. Conclusions: Preventive genetic testing in relatives of patients affected by ovarian cancer is cost-effective and represents a sustainable cost for the National Healthcare System in Italia, also in the light of its reference values.
