Sorafenib plus hepatic arterial infusion chemotherapy with oxaliplatin versus sorafenib alone for advanced hepatocellular carcinoma

ObjectiveTo compare the efficacy of sorafenib plus hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin to that of sorafenib alone in patients with advanced hepatocellular carcinoma (HCC).MethodsThis was a retrospective, single-center trial. Between April 3, 2017 and July 2, 2018, 104 patients with Child-Pugh A and advanced HCC received either 400 mg of sorafenib orally twice daily plus HAIC with oxaliplatin (oxaliplatin 85 mg/m², every 3 weeks via repetitive catheterization) (n = 46, soraOXA group) or 400 mg of only sorafenib orally twice daily (n = 58, sorafenib group). Overall survival, progression-free survival, objective response rate, and treatment-related adverse events were compared.ResultsThe median overall survival was 9.37 months (95% CI, 7.05–11.68) in the soraOXA group versus 4.8 months (95% CI, 2.98–6.62) in the sorafenib group (HR 0.46 [95% CI, 0.29–0.72]; P < 0.001). The soraOXA group also showed a higher objective response rate (16 [34.8%] vs 1 [1.7%]; P < 0.001) and a longer progression-free survival rate (5.5 months [95% CI, 2.32–8.68] vs 2.4 months [95% CI, 1.65–3.15], HR 0.54 [95% CI, 0.36–0.81], P = 0.003) than the sorafenib group. There was no significant difference in the overall incidence of any grade adverse events, grade 3/4 adverse events, serious adverse events, or incidence of treatment termination due to adverse events between the two groups.ConclusionCompared with sorafenib alone, sorafenib plus HAIC with oxaliplatin showed favorable treatment outcomes in patients with advanced HCC. The merits of this approach need to be established with a prospective trial.
