Abstract
Background/Aim: The reimbursement criteria of sorafenib for advanced hepatocellular carcinoma (HCC) were expanded in 2016 by Taiwan’s National Health Insurance (NHI) to include patients without macrovascular invasion or extrahepatic spread. This study explored sorafenib treatment outcomes before and after this expansion. Patients and Methods: The NHI database was searched for patients who initiated sorafenib treatment between January 1, 2013, and December 31, 2017. Clinical variables were retrieved from the Taiwan Cancer Registry database. Overall survival (OS) and time to treatment discontinuation (TTD) were calculated as the times from the first sorafenib prescription date until death and the final prescription date, respectively. Results: A total of 13,862 patients were included. The median age was 64 years, 78.1% of patients were male. Approximately a quarter of patients (25.1%) received sorafenib after the criteria expansion and exhibited significantly longer OS (median 7.9 vs. 6.6 months, p<0.001) and TTD (median 3.0 vs. 2.6 months, p=0.003) compared with patients who started before. These results were verified in patients with available data regarding clinical prognostic factors (n=9,378, 67.7% of the entire study population). In the multivariate analysis, sorafenib prescription after criteria expansion remained an independent predictor of longer OS [hazard ratio (HR)=0.87, p<0.001] and TTD (HR=0.93, p=0.004). In the subgroup analysis, these trends were consistently observed across different patient subgroups. Conclusion: Patients with HCC who received sorafenib treatment after the reimbursement criteria expansion exhibited longer OS and TTD.
