Combination therapy of radiofrequency ablation and transarterial chemoembolization in recurrent hepatocellular carcinoma after hepatectomy compared with single treatment.
AIM: To assess the efficacy and safety of radiofrequency ablation (RFA) combined with transarterial chemoembolization (TACE) in recurrent hepatocellular carcinoma (HCC) after hepatectomy and to compare its outcome with a single modality.
METHOD: We retrospectively studied 103 patients with recurrent HCCs after hepatectomy who were excluded from repeat hepatectomy. Of them, 81 patients were male and 22 were female (mean age 55.8 +/- 10.7 years; range, 30-80 years). According to treatment modality, these patients were divided into three groups: RFA was used as the sole first-line anticancer treatment in 37 patients (RFA group); TACE was used as the sole first-line anticancer treatment in 35 patients (TACE group). RFA followed by TACE was performed in 31 patients (combination group). There was no significant difference in clinical material between the three groups. Indices including treatment success rate, intrahepatic recurrence rate and survival were obtained for analysis and comparison.
RESULTS: The treatment success rate of the combination group was significantly higher than that of the TACE group (93.5 vs. 68.6%, P = 0.011). The intrahepatic recurrence rate of the combination group was significantly lower than that of the TACE group (20.7 vs 57.1%, P = 0.002) and the RFA group (20.7 vs 43.2%, P = 0.036). The overall 1-, 3- and 5-year survival rates were 73.9, 51.1 and 28.0% respectively in the RFA group; 65.8, 38.9 and 19.5% respectively in the TACE group; and 88.5, 64.6 and 44.3% respectively in the combination group. There was a significant difference in survival between the combination group and the TACE group (P = 0.028).
CONCLUSION: RFA combined with TACE was more effective in treating recurrent HCC after hepatectomy compared to single RFA or TACE treatment. This combination therapy can thus be a valuable choice of treatment for recurrent HCC.
