Transarterial therapies in patients with hepatocellular carcinoma eligible for transarterial embolization: a US cost-effectiveness analysis.

The Barcelona Clinic Liver Cancer guideline recommends the use of transarterial radioembolization (TARE), conventional (cTACE), or drug-eluting bead transarterial chemoembolization (DEE-TACE) for treating hepatocellular carcinoma (HCC). This study evaluated the cost-effectiveness of TARE versus two alternative embolization treatments (cTACE and DEE-TACE) in treating patients with unresectable early- to intermediate-stage HCC.A cohort-based Markov model was developed to analyze the costs and benefits of these treatments from a US healthcare perspective within a 5-year time horizon. A 20-year time horizon was assessed as a scenario. In the model, patients were assigned to receive TARE, cTACE, or DEE-TACE and remained in the "watch and wait" stage for tumor downstaging. Data used in the model was taken from previous studies and in consultation with clinical experts. The benefits of the treatments were measured by considering the impact on the patient's quality of life. The costs associated with the treatments were obtained from various sources, including reports, publicly available databases, and published literature.The findings show that TARE is not only cost-saving compared to cTACE but also results in a higher number of quality-adjusted life years (QALYs) per person. While TARE was more expensive than DEE-TACE, it produced more QALYs, further indicating more favorable patient outcomes and overall treatment effectiveness. These findings could potentially impact resource allocation and decision-making for the treatment of HCC.
