Efficacy and safety of TACE combined with TKIs and PD-1 inhibitors in HCC patients with prior TIPS.

PURPOSE

To compare the efficacy and safety of TACE combined with TKIs and PD-1 inhibitors between HCC patients with and without prior TIPS.

METHODS

This retrospective propensity score matching (PSM) study included advanced HCC patients treated with prior TIPS followed by TKIs, PD-1 inhibitors, and TACE between January 2021 and January 2023. Patients were matched with a control group of HCC patients who had not undergone TIPS (non-TIPS). Outcome measures included objective response rate (ORR) using modified RECIST (mRECIST v1.1), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety assessed by CTCAE v5.0.

RESULTS

A total of 172 patients were included before PSM. After PSM, 42 patients with prior TIPS were matched with 71 non-TIPS patients. ORR was 31.0% in the TIPS group and 57.7% in the non-TIPS group (p = 0.007), Both PFS and OS were longer in the non-TIPS group, with a median PFS of 7.9 months for TIPS patients versus 12.3 months for non-TIPS patients (hazard ratio [HR] = 2.253, p < 0.001), and a median OS of 13.5 months versus 21.1 months, respectively (HR = 2.282, p = 0.002). Treatment-related adverse events showed no significant differences between the two groups.

CONCLUSION

TACE combined with TKIs and PD-1 inhibitors showed lower efficacy in HCC patients with prior TIPS, but it remains a viable option, providing a favorable safety profile and effective disease control.
