Cost-effectiveness analysis of potentially curative and combination treatments for hepatocellular carcinoma with person-level data in a Canadian setting

Abstract

Patients with early-stage hepatocellular carcinoma (HCC) are potential candidates for curative treatments such as radiofrequency ablation (RFA), surgical resection (SR), or liver transplantation (LT), which have demonstrated a significant survival benefit. We aimed to estimate the cost-effectiveness of curative and combination treatment strategies among patients diagnosed with HCC during 2002–2010. This study used Ontario Cancer Registry-linked administrative data to estimate effectiveness and costs (2013 USD) of the treatment strategies from the healthcare payer's perspective. Multiple imputation by logistic regression was used to handle missing data. A net benefit regression approach of baseline important covariates and propensity score adjustment were used to calculate incremental net benefit to generate incremental cost-effectiveness ratio (ICER) and uncertainty measures. Among 2,222 patients diagnosed with HCC, 10.5%, 14.1%, and 10.3% received RFA, SR, and LT monotherapy, respectively; 0.5–3.1% dual treatments; and 0.5% triple treatments. Compared with no treatment (53.2%), transarterial chemoembolization (TACE) + RFA (average $2,465, 95% CI: −$20,000–$36,600/quality-adjusted life years [QALY]) or RFA monotherapy ($15,553, 95% CI: $3,500–$28,500/QALY) appears to be the most cost-effective modality with lowest ICER value. The cost-effectiveness acceptability curve showed that if the relevant threshold was $50,000/QALY, RFA monotherapy and TACE+ RFA would have a cost-effectiveness probability of 100%. Strategies using LT delivered the most additional QALYs and became cost-effective at a threshold of $77,000/QALY. Our findings found that TACE+ RFA dual treatment or RFA monotherapy appears to be the most cost-effective curative treatment for patients with potential early stage of HCC in Ontario. These findings highlight the importance of identifying and measuring differential benefits, costs, and cost-effectiveness of alternative HCC curative treatments in order to evaluate whether they are providing good value for money in the real world.

The aim of this article was to estimate the cost-effectiveness of mutually exclusive potentially curative monotherapies such as radiofrequency ablation (RFA), surgical resection (SR), or liver transplantation (LT) and combination therapies with palliative treatment (transarterial chemoembolization, TACE) among patients diagnosed with hepatocellular carcinoma (HCC) during 2002–2010. Compared with no treatment, TACE plus RFA (average $2,465, 95% CI: −$20,000–$36,600/quality-adjusted life years [QALY]) or RFA monotherapy ($15,553, 95% CI: $3,500–$28,500/QALY) appears to be the most cost-effective modality with lowest incremental cost-effectiveness ratio (ICER) value. Our findings found that TACE plus RFA dual treatment or RFA monotherapy appears to be the most cost-effective curative treatment for patients with potential early stage of HCC in Ontario, which may potentially provide good value for money in the real world within the context of an organized healthcare system.
