Abstract

AimsTo assess whether combining percutaneous radiofrequency ablation (PRFA) with transcatheter arterial chemoembolization (TACE) was better than PRFA alone for hepatocellular carcinoma (HCC).Materials and methodsOne hundered twenty patients (with a solitary HCC ≤ 7.0 cm in diameter or multiple HCC (≤3), each ≤3.0 cm in diameter) treated with PRFA combined with TACE were compared with 120 well-matched controls selected from a pool of 652 patients who received PRFA alone during the study period.ResultsThe 1-, 2-, 3-, 5-year overall survival rates for the TACE-PRFA and PRFA groups were 93%, 83%, 75%, 50%, and 89%, 76%, 64%, 42%, respectively (p = .045). Subgroup analyses showed the survival for the TACE-PRFA group was better than the PRFA group for tumors >5.0 cm (p = .031) and for multiple tumors (p = .032), but not for tumors ≤5.0 cm (p = .319) and for solitary tumor (p = .128). The 1-, 2-, 3-, 5-year progression free survival (PFS) for the TACE-PRFA and PRFA groups was 90%, 76%, 63%, 42%, and 76%, 60%, 47%, 30%, respectively (p = .002). Child-pugh class, Diameter of tumor and hepatitis B surface antigen (HBsAg) were significant prognostic factors.ConclusionPatients treated with TACE-PRFA had better overall survivals than PRFA alone, but only in a subgroup of patients with tumor >5 cm or multiple tumors.
