Patients with extrahepatic metastasis or inferior vena cava invasion were excluded. The primary endpoint was overall survival (OS). The secondary endpoints were safety (assessed using Common Terminology Criteria for Adverse Events v5.0), the response rate at 1 month, and the identification of prognostic factors. The median OS was calculated using the Kaplan–Meier method. The response rate was evaluated according to the modified Response Evaluation Criteria in Solid Tumors. Prognostic factors were investigated by univariate and multivariable analysis using the Cox proportional hazards model.Results: The median OS was 13 months. BCLC stage and presence of portal vein invasion were not significantly associated with OS. There were no grade ≥ 3 adverse events. The Child–Pugh class did not decline after treatment in 31 of 34 patients. The overall response rate was 14.2% and the disease control rate was 100%. Significant prognostic factors were alcoholic liver disease, Child–Pugh score of ≥ 8, and microsphere size of 50– 100 μm.Conclusion: DEM-TACE combined with intra-arterial infusion of bevacizumab is safe and effective, and it could be a treatment option for unresectable HCCs.Keywords: bevacizumab, hepatocellular carcinoma, microspheres, transarterial chemoembolization |
