Abstract

Purpose: Managing hepatocellular carcinoma (HCC) in patients with a transjugular intrahepatic portosystemic shunt (TIPS) is becoming increasingly common. This study aimed to evaluate the safety and efficacy of percutaneous thermal ablation for treating HCC in patients with TIPS.

Methods: This retrospective longitudinal study was conducted at Nantes University Hospital. The main inclusion criteria were patients undergoing percutaneous thermal ablation for HCC. Patients with a pre-existing TIPS were included in the 'TIPS group'. A 1:1 control group without TIPS, the 'n-TIPS group', was created for this case-control study. The primary endpoints were overall survival and progression-free survival over 12 months. Safety was assessed by comparing complications between the groups.

Results: Between 2008 and 2020, 371 patients underwent percutaneous thermal ablation for HCC. The 'TIPS group' included 34 patients (66 nodules), while 34 patients (84 nodules) were randomly assigned to the 'n-TIPS group.' Overall survival rates at 1 year were 97% and 94% respectively (p = 0.52). The progression-free survival rate was 68% and 57% respectively (p = 0.35). No deaths occurred within 30 days post-procedure. There were 3 immediate complications in the TIPS group and 4 in the n-TIPS group (p = 1), none of which were related to the TIPS, including thrombosis.

Conclusion: Percutaneous thermal ablation for HCC in patients with TIPS appears to be as safe and effective as in TIPS-naïve patients. These results suggest that the presence of a TIPS should not be considered a contraindication for percutaneous thermal ablation in treating HCC.
