Sorafenib was the first systemic drug approved in 2007 for the treatment of hepatocellular carcinoma and standard of care for frontline therapy. Clinical studies demonstrated some benefits of sorafenib on overall survival (OS), its efficacy against for tumor response remains moderate. In recent years, the combination therapy of transcatheter arterial chemoembolization (TACE) plus sorafenib has been increasingly used in patients with advanced HCC. Patients with advanced HCC patients who received sorafenib in a reginal teaching Hospital, between January 2012 and December 2019 were retrospectively enrolled in this study. We evaluated their clinical outcomes of those with surgery experience and without surgery experience. Among 147 patients who were eligible for the analysis and through propensity score matching, we divided patients into the No surgery experience arm (n = 38) and Surgery experience arm (n = 38; patients received sorafenib for advanced recurrence HCC). The primary endpoint was overall survival (OS) and progression free survival (PFS). The Surgery experience arm had significantly improved the median overall survival was 446 vs. 150 days (hazard ratio 0.44; 95% confidence interval 0.27–0.73，P = 0.001) and median progression free survival 134 vs. 56 days (hazard ratio 0.56; 95% confidence interval 0.37–0.94，P=0.003). The median OS and PFS were significantly longer in the Surgery experience arm than in the No surgery experience arm. We conclude that debulking the intrahepatic tumor burden is prolong survival time of patients with intermediate and advanced-stage HCC. Therefore, liver resection the first choice in the treatment of patients with intermediate and advanced-stage HCC. The benefits of surgical treatment even enable patients with advanced recurrence HCCs to achieve better survival.肝癌手術切除蕾莎瓦肝癌復發Hepatocellular carcinomaLiver resectionSorafenibRecurrence HCCthesis
