This study aimed to assess the efficacy of sorafenib treatment for advanced HCC in a clinical practice using a nationwide population study. Methods: All patients registered with a diagnosis of primary HCC and identified as having been prescribed sorafenib between August 2012 and December 2015 were selected from a national database and retrospectively reviewed. Outcomes related to prescription of sorafenib for these patients were further assessed. Results: A total of 9,738 patients were enrolled and analyzed. As a result, 32.33% of patients had an initial treatment response and were eligible for the prescribed second term (240 tablets/term) of sorafenib and 8.91% of patients received more than three terms of sorafenib. Meanwhile, the duration of sorafenib usage beyond 6 months was noted in 15.49% of patients, including 10.59% of patients with a period of usage between 6 and 12 months and 4.9% of patients with more than 12 months usage. Survival analysis showed that patients who received locoregional therapy plus sorafenib had significantly better survival rates than those who underwent only sorafenib treatment. Certain patients who underwent hepatectomy (n=12) or liver transplantation (n=13) were subsequently free of HCC. Conclusion: The disease control rate of sorafenib in advanced HCC patients in this study seemed similarly poorer as what has been previously reported by clinical trials. The combination of sorafenib and additional treatments could perhaps provide survival benefits and possibly cure disease in combination with surgical management.
