Endoarterial Treatment in Combination With Percutaneous Thermoablation for Medium-sized and Oligonodular Hepatocellular Carcinomas

Background: The association of transcatheter arterial chemotherapy infusion (TAC) with percutaneous ablation (PT) has been introduced as a method to increase the ablative zone. The aim of this study was to evaluate the efficacy of PT and TAC performed in a single session for HCCs between 30 and 50 mm or oligonodular up to 30 mm. Methods: Thirty patients with a histologically proven HCC, uninodular between 30 and 50 mm or oligonodular (n≤3) up to 30 mm, treatment-naïve and non-metastatic, received combination treatment ("PT+TAC group"). A "control" group consisted of 34 patients with uninodular HCC up to 30 mm without any poor prognostic criteria treated with PT alone ("PT group").
