Abstract
BACKGROUND: This study aimed to investigate the pharmaco-economic implications of FOLFOX4 or sorafenib for advanced hepatocellular carcinoma in China. METHODS: To conduct the analysis, we performed a Markov model to simulate the process of advanced HCC treated with sorafenib or FOLFOX4. Clinical data were obtained from the ORIENTAL trial and the EACH trial. Incremental cost-effectiveness ratio was regarded as the primary outcome in the analysis. One-way sensitivity analysis as well as probabilistic sensitivity analysis was performed to explore the impact of essential variables on the results of the analysis. RESULTS: Treatment with sorafenib provided an effectiveness gain of 0.3935 quality-adjusted life year at an average cost of $18,748.00, whereas chemotherapy of FOLFOX4 brought 0.3808 quality-adjusted life year at a cost of $6876.02. The incremental cost-effectiveness ratio of FOLFOX4 versus sorafenib was $934,801.57/QALY. In a probabilistic sensitivity analysis based on a Monte Carlo simulation of 1000 items, the probabilities of FOLFOX4 and sorafenib being cost-effective were 100% and 0% using a willingness-to-pay threshold of $20,301.00 per quality-adjusted life year. CONCLUSIONS: FOLFOX4 chemotherapy is likely to be a cost-effective option compared with sorafenib in the treatment of advanced hepatocellular carcinoma in China.
