Methods: Patients were assigned to treatment with transcatheter arterial chemoembolization (TACE) combined with 131I-metuximab or TACE alone. The primary outcome was overall tumor recurrence. The secondary outcomes were safety and overall survival. Results: The median time to tumor recurrence was 6 months in the TACE+131I-metuximab group (n = 160) and 3 months in the TACE group (n = 160) (hazard ratio, 0.55; 95% confidence interval, 0.43 to 0.70; P &lt; 0.001). The median overall survival was 28 months in the TACE+131I-metuximab group and 19 months in the TACE group (hazard ratio, 0.62; 95% confidence interval, 0.47 to 0.82; P = 0.001). Conclusion: TACE+131I-metuximab showed a greater anti-recurrence benefit, significantly improved the 5-year survival of patients with advanced hepatocellular carcinoma, and was well tolerated by patients.
