RESUMO
OBJECTIVE: The aim of this study is to conduct a cost-effectiveness analysis of 5-fluorouracil 0.5%/salicylic acid 10% (5-FU/SA) in the treatment of isolated hyperkeratotic actinic keratosis lesions in Spain. METHODS: An analytical decision-making model was constructed to compare whether 5-FU/SA was a cost-effective option compared with cryotherapy from the perspective of the Spanish National Health System with a time horizon of 6 months. Costs were expressed in 2014 euros. RESULTS: The cost of patients with hyperkeratotic actinic keratosis treated with 5-FU/SA or cryotherapy was 266 and 285, respectively. 5-FU/SA was associated with higher rates of treatment success and, consequently, more quality-adjusted life years, than cryotherapy. Therefore, 5-FU/SA was the dominant treatment, as it was associated with a lower treatment cost and greater effectiveness than cryotherapy. CONCLUSIONS: Economically, 5-FU/SA was a dominant option compared with cryotherapy in the treatment of isolated hyperkeratotic actinic keratosis lesions in Spain.
