Purpose
To compare the efficacy and safety of transcatheter arterial chemoembolization (TACE) in combination with tyrosinkinase inhibitors (TKI) and PD-1 inhibitors, versus TACE monotherapy for the treatment of ruptured hepatocellular carcinoma (HCC).
Materials and Methods
This study included 104 patients with ruptured HCC receiving either combination therapy or TACE monotherapy at two centers between June 2015 and June 2022. Propensity score matching (PSM) analysis was used at a 1:2 ratio to reduce bias between the two groups. The primary outcome measures were overall survival (OS) and progression-free survival (PFS), and the secondary outcome measures were the occurrence of adverse events (AEs, Common Terminology Criteria for AEs, version 5.0.) and the peritoneal metastasis rate.
Results
A total of 69 patients were enrolled after PSM, including 23 patients in the combination group and 46 patients in the monotherapy group. The combination group exhibited a significantly longer median OS (553 days, 95% confidence interval [CI] 222.6–883.9) compared to the monotherapy group (105 days, 95% CI 81.2–128.7; P < 0.001). Similarly, the combination group showed a better median PFS (356 days, 95% CI 299.5–412.4) compared to the monotherapy group (97 days, 95% CI 75.9–118.1; P < 0.001). Moreover, there was no significant difference in the peritoneal metastasis rate (combination group: 8.6% vs. monotherapy group: 26.1%, P = 0.119). Grade 3 AEs occurred at a rate of 21.7% and 13% in combination and monotherapy groups, respectively. No Grade 4/5 AEs were observed in either group.
Conclusions
Our study demonstrated that the combination of TACE with TKI and PD-1 inhibitors significantly enhances OS and PFS compared to TACE monotherapy in ruptured HCC patients. Furthermore, this combined approach exhibited an acceptable safety profile.
