Cost–effectiveness of treatments for high-risk myelodysplastic syndromes after failure of first-line hypomethylating agent therapy
2016
Purpose: To evaluate optimal salvage therapy in high-risk myelodysplastic syndromes patients who have failed a first-line hypomethylating agent (HMA) therapy, given that treatment choice is challenging. Methods: Using published literature and expert opinion, we developed a Markov model to evaluate the cost–effectiveness of current treatments for patients who failed first-line HMA therapy. The model predicted costs, life years, quality-adjusted life years and incremental cost-effectiveness ratios. Sensitivity analyses were conducted to assess the impact of uncertainty in model inputs. Results: Supportive care was the least expensive option ($65,704/patient) with the shortest survival (0.48 years). Low- and high-intensity chemotherapies and hematopoietic cell transplantation increased survival and costs with incremental cost-effectiveness ratios of $108,808, 306,103 and 318,163/life year, respectively. Switching HMA was more costly and less efficacious than another treatment option, namely low-intensity che...
