Abstract
OBJECTIVE
This study compared the efficacy and safety of the transarterial chemoembolization with CalliSpheres® drug-eluting beads loading with doxorubicin (DEB-TACE) versus conventional lipiodol (cTACE) in patients with unresectable hepatocellular carcinoma (HCC).
METHODS
A randomized controlled trial (RCT) was conducted with 144 patients, who were randomly assigned to receive either DEB-TACE with doxorubicin-loaded CalliSpheres® microspheres or cTACE with doxorubicin-lipiodol emulsion. Patients were followed up for 12 months, with assessments at 3 and 12 months posttreatment. The primary endpoint was the clinical response rate (CR), and the secondary endpoints were the overall survival (OS), the progression-free survival (PFS), and the safety profile of the two treatments.
RESULTS
The results showed that DEB-TACE was superior to cTACE in terms of CR (50.0% vs 30.6% at 3 months, p = 0.03; 43.1% vs 25.0% at 12 months, p = 0.04), OS (18.2 months vs 14.6 months, p < 0.05), and PFS (7.4 months vs 4.8 months, p < 0.05), and that the safety profile of the two treatments was similar (p > 0.05 for all comparisons). However, the efficacy of DEB-TACE and cTACE varied according to the tumor morphology. DEB-TACE showed better CR rates in patients with nodular tumors, while no significant difference in CR between the two groups in patients with infiltrative tumors.
CONCLUSION
DEB-TACE showed superior efficacy to cTACE in terms of CR, OS, and PFS, particularly in patients with nodular tumors, while maintaining a similar safety profile. These findings suggest that tumor morphology could inform treatment decisions for TACE in HCC patients.
