Introduction:
We aim to assess the outcomes of percutaneous ablation of locally advanced HCC in a tertiary center, which is usually not indicated. We compared to sorafenib or trans-arterial radioembolization (TARE).
Methods:
We included 272 patients with HCC and tumor portal invasion treated by percutaneous ablation (n = 44) assessed retrospectively from one center compared to a control group from the SARAH trial including patients treated with sorafenib (n = 123) or TARE (n = 105). A propensity-score matching was performed in a subgroup of patients with similar baselines characteristics.
Results:
84% of patients treated by ablation were male with a unique nodule (median size 50 mm) in 72.7% of the case. Complete tumor ablation was achieved in 75% of the patients with 20% Dindo-Clavien III-V adverse events including 6.8% of 90-days mortality. Sum of tumor size ≥70 mm was associated with incomplete ablation (p = 0.0239) and a higher risk of death (p = 0.0375). Patients in control group had a higher tumor burden, and more Vp3/4 compared to ablation group. Median overall survival was similar in the ablation and in the control group (16.4 and 14.0 months respectively, p = 0.48). The median progression-free survival was 6.6 months in ablation group compared to 4.2 months in the control group (p = 0.12).
Conclusion:
Percutaneous ablation for locally advanced HCC was feasible and associated with similar long-term outcomes to sorafenib or TARE.
