TACE Combined with Ralox-HAIC (Oxaliplatin Puls Raltitrexed) and System Therapy in Patients with Unresectable Hepatocellular Carcinoma.

OBJECTIVE

To retrospective analysis the efficacy and safety of Transarterial Chemoembolization (TACE) combined with Hepatic Arterial Infusion Chemotherapy (Ralox-HAIC, Oxaliplatin + Raltitrexed) and systemic therapy in patients with unresectable Hepatocellular Carcinoma (uHCC).

METHODS

Clinical data of patients with uHCC who received TACE combined with Ralox-HAIC followed by sequential systemic therapy at our hospital between January 2023 and December 2024 were analyzed. The primary endpoint was Objective Response Rate (ORR). Secondary endpoints included Progression-Free Survival (PFS), Overall Survival (OS) and treatment safety.

RESULTS

A total of thirty-six patients with complete data were included. Efficacy evaluation showed: Complete Response (CR) in 6 cases (16.67%), Partial Response (PR) in 22 cases (61.11%), Stable Disease (SD) in 5 cases (13.89%), and Progressive Disease (PD) in 2 cases (5.56%). The ORR was 77.78%, and the Disease Control Rate (DCR) was 91.67%. The median PFS was 12.0 months, and the median OS was 19.0months. The one-year and two-year survival rates were 89% and 38%, respectively. No Grade 4 treatment-related adverse events or treatment-related deaths occurred.

CONCLUSION

TACE combined with Ralox-HAIC and systemic therapy demonstrated a high ORR and DCR with manageable safety in uHCC, warranting further prospective studies for validation.
