ARTICLE HIGHLIGHTS
Research background

Sorafenib has been proven effective for advanced hepatocellular carcinoma (HCC), transarterial chemoembolization (TACE) is the standard therapy for intermediate HCC, and hepatic arterial infusion chemotherapy (HAIC) is a safe and effective treatment for advanced HCC. Herein, we aimed to identify the safety and efficacy of combining sorafenib with HAIC after TACE for intermediate and advanced HCC.

Research motivation

Although there are many treatment methods for HCC, the therapeutic effect is very limited and does not significantly prolong patient survival. Safer and more effective protocols need to be developed to improve therapeutic effects.

Research objectives

To provide an effective combined treatment protocol based on previous studies.

Research methods

All patients initially received the standard 400 mg dose of sorafenib twice daily before TACE-HAIC. Participants at our institute with intermediate and advanced HCC underwent routine TACE. Then, the catheter used for embolization was kept in place in the feeding artery of the tumor, and oxaliplatin was intra-arterially administered for 6 h, followed by 5-fluorouracil (5-FU) for 18 h, and folinic acid was intravenously administered for 2 h.

Research results

The overall response rate was 42.4%. The disease control rate was 87.9%. The grade 3-4 toxicities consisted of thrombocytopenia (4.5%), neutropenia (3.0%), and elevated aspartate aminotransferase (12.2%). Hand-foot skin reaction was also observed (40.9%). The median progression-free survival was 13.1 mo, (13.5 mo in participants with Barcelona Clinic Liver Cancer (BCLC) stage B disease and 9.4 mo in participants with BCLC stage C disease). The 6-mo, 12-mo, and 24-mo PFS rates were 75.0%, 54.7%, and 30.0%, respectively. The median overall survival was 21.8 mo.

Research conclusions

Sorafenib combined with HAIC (folinic acid, 5-FU, and oxaliplatin) after TACE may be a feasible treatment choice for intermediate and advanced HCC based on patient tolerance and survival.

Research perspectives

The combination of sorafenib and TACE-HAIC has been shown to be effective with limited complications. Prospective randomized controlled trials are needed to confirm the effect of this combination therapy.
