Background:
For advanced hepatocellular carcinoma (HCC), sorafenib remains the established therapy. PD-1/PD-L1 inhibitors plus antiangiogenic drugs (PIAD) as a new therapeutic approach for advanced HCC is still a subject of clinical debate regarding whether they offer improved treatment outcomes. This study was conducted to compare the two treatments in terms of antitumor efficacy and safety.
Methods:
Randomized controlled trials (RCTs) comparing PIAD and sorafenib for advanced HCC were retrieved from six databases. Survival (overall survival [OS] and progression-free survival [PFS]) were the main outcomes measured. Secondary endpoints included responses, adverse events (AEs), and effects on quality of life.
Results:
Seven studies based on four RCTs (CARES-310, COSMIC-312, IMbrave150, and ORIENT-32) were included. The PIAD group exhibited better OS (hazard ratio [HR]: 0.69, 95% confidence interval [CI]: [0.53, 0.89], P = 0.005), and PFS (HR: 0.60, 95% CI: [0.53, 0.67], P < 0.00001). The survival advantages of OS and PFS were confirmed in almost all subgroups. The PIAD group exhibited higher OS rates at 6-18 months and PFS rates at 6-12 months. Additionally, the objective response rate, disease control rate, complete response, and partial response were higher in PIAD group. The PIAD group had a delayed decline in quality of life, physical functioning, and role functioning. However, the PIAD group experienced more grades 3-5 and serious AEs, along with treatment discontinuation, dose reduction, and dose interruption.
Conclusions:
PIAD appears to be better than sorafenib for advanced HCC with better survival and responses. However, its higher rate of AEs requires cautious attention.
