Abstract:

Objective

To compare the efficacy of re-hepatectomy and percutaneous ablation in the treatment of recurrent hepatoblastoma (HB).

Methods

We retrospectively analyzed 22 recurrent HB patients who received re-hepatectomy (n=14) or percutaneous ablation (n=8) at the First Affiliated Hospital of Sun Yat-sen University from January 2013 to March 2019. The baseline characteristics and rate of complications were compared by the t-test, Wilcoxon test, or χ2-test according to the data type. Survival curves of children after first relapse treatment were drawn, and 3-year overall survival and event-free survival in the two groups were compared using the log-rank test.

Results

There were no significant differences in baseline characteristics between the two groups. The 3-year overall survival rate in the ablation group and re-hepatectomy group was 75.0% and 78.6% (P=0.814), and the 3-year event-free survival rate was 50.0% and 40.0%, respectively (P=0.880). No severe complications occurred in either group. The rate of complications was significantly higher in the surgery group than in the ablation group (78.6% vs 25.0%, χ2=6.044, P=0.026).

Conclusion

Percutaneous ablation for recurrent HB is safe and effective, with no significant difference in prognosis compared with secondary surgery.
