Transarterial Chemoembolization Combined With Radiofrequency Ablation Repeat Hepatectomy for Recurrent Hepatocellular Carcinoma After Curative Resection: A 10-Year Single-Center Comparative Study.

BACKGROUND

The purpose of this study was to compare the efficacy and safety of transarterial chemoembolization (TACE) in combination with radiofrequency ablation (RFA) (TACE-RFA) and repeat hepatectomy in the treatment of recurrent hepatocellular carcinoma (HCC) after curative resection.

METHODS

This retrospective study evaluated consecutive medical records of patients who received either TACE-RFA or repeat hepatectomy between January 2010 and May 2021. Overall survival (OS), progression-free survival (PFS), and complications were compared.

RESULTS

Of the 2672 patients who received either TACE-RFA or repeat hepatectomy, 111 eligible patients were included in our study, 63 in the TACE-RFA group and 48 in the repeat hepatectomy group. The median OS was 38 months in the TACE-RFA group and 42 months in the repeat hepatectomy group, with no statistically difference between the two groups (=0.45). Meanwhile, there was also no statistically significant difference in PFS between the two groups (=0.634). Although both groups achieved similar outcomes, the rate of major complications was significantly higher in the repeat hepatectomy group (=0.003).

CONCLUSIONS

Patients with recurrent HCC in the TACE-RFA group and the repeat hepatectomy group had similar OS and PFS regardless of the patient's tumor diameter, but the TACE-RFA group was safer and more minimally invasive.
