Popis: Simple Summary In this study, efficacy and safety of embolization alone and trans-arterial chemoembolization were compared in 265 patients with intermediate stage hepatocellular carcinoma. Trans-arterial chemoembolization was associated with a significant increase of complete radiological response, but without significant impact on overall response, and survival outcomes after propensity score matching. Both techniques showed similar safety profiles. To this day, embolization alone and trans-arterial chemoembolization are two available options in the treatment of intermediate stage hepatocellular carcinoma. Abstract No definitive conclusion could be reached about the role of chemotherapy in adjunction of embolization in the treatment of hepatocellular carcinoma (HCC). We aim to compare radiological response, toxicity and long-term outcomes of patients with hepatocellular carcinoma (HCC) treated by trans-arterial bland embolization (TAE) versus trans-arterial chemoembolization (TACE). We retrospectively included 265 patients with HCC treated by a first session of TACE or TAE in two centers. Clinical and biological features were recorded before the treatment and radiological response was assessed after the first treatment using modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria. Correlation between the treatment and overall, progression-free and transplantation-free survival was performed after adjustment using a propensity score matching: 86 patients were treated by bland embolization and 179 patients by TACE, including 44 patients with drug-eluting beads and 135 with lipiodol TACE, 89.8% of patients were male with a median age of 65 years old. Cirrhosis was present in 90.9% of patients with a Child Pugh score A in 84% of cases. After adjustment, no difference in the rate of AE, including liver failure, was observed between the two treatments. TACE was associated with a significant increase in complete radiological response (odds ratio (OR) = 8.5 (95% confidence interval (CI): 2.8–25.4)) but not in the overall response rate (OR = 2.2 (95% CI = 0.8–5.8)). No difference in terms of overall survival (p = 0.3905), progression-free survival (p = 0.4478) and transplantation-free survival (p = 0.9020) was observed between TACE and TAE. TACE was associated with a higher rate of complete radiological response but without any impact on overall radiological response, progression-free survival and overall survival compared to TAE.
