Background & Aims: The effect of transarterial chemoembolization (TACE) plus radiofrequency ablation (RFA) (TACE-RFA) for hepatocellular carcinoma (HCC) in high-risk locations is not satisfactory. The aim of this study was to compare the clinical outcomes of TACE-RFA plus iodine-125 ( 125 I) seed implantation (TACE-RFA- 125 I) therapy with those of TACE-RFA for unresectable HCC (≤ 5 cm) in high-risk locations. Methods: From January 2010 to June 2023, the clinical data of 126 patients with unresectable HCC (≤ 5 cm) in high-risk locations who received TACE-RFA- 125 I or TACE-RFA treatment were retrospectively analyzed. The clinical outcomes between the two groups were compared after propensity score matching (PSM) analysis. Results: Forty-six pairs of patients were matched. The local progression-free survival rates at 1-, 2-, 3-, 4-, and 5-years were 100%, 82.4%, 74.8%, 63.5%, and 54% in the TACE-RFA- 125 I group, which were significantly higher than 91.3%, 69.4%, 50.7%, 29.4%, and 26.7% in the TACE-RFA group, respectively ( p = 0.004). The median progression-free survival in the TACE-RFA- 125 I group was significantly longer than that in the TACE-RFA group ( p = 0.002). The overall survival rates at 1-, 2-, 3-, 4-, and 5-years were 100%, 93.4%, 80.7%, 74.9%, and 64.7% in the TACE-RFA- 125 I group, which were significantly higher than 97.8%, 78%, 68.6%, 51.1%, and 45.3% in the TACE-RFA group, respectively ( p = 0.011). There was no occurrence of major complications or procedure...
