RESUMO
Objectives: To evaluate the efficacy and safety of transarterial chemoembolization (TACE) with drug-eluting beads (DEB-TACE) and lipiodol (DEB-Lipiodol TACE) in the treatment of unresectable hepatocellular carcinoma (HCC) patients. Materials and Methods: The medical records of consecutive unresectable HCC patients who underwent DEB-TACE or DEB-Lipiodol TACE from June 2016 to July 2021 were retrospectively evaluated. Therapeutic response, overall survival (OS), progression-free survival (PFS), and adverse events (AEs) were compared among the groups. Results: Three hundred and twenty-seven patients were enrolled in the study, including 293 patients in the DEB-TACE group and 34 patients in the DEB-Lipiodol TACE group. The objective response rate in the DEB-Lipiodol TACE group was 17.6%, significantly higher than that in the DEB-TACE group (5.8%, P=0.011). Similarly, DEB-Lipiodol TACE group also had a higher disease control rate (91.2% vs 68.6%, P=0.006). Median OS was 13 months (95% CI: 11.0 months and 15.0 months) and 22 months (95% CI: 17.3 months and 26.7 months) in the DEB-TACE group and DEB-Lipiodol TACE group, respectively (P=0.041). Meanwhile, median PFS was 7 months (95% CI: 5.2 months and 8.8 months) in the DEB-TACE group and 12 months (95% CI: 7.9 months and 16.1 months) in the DEB-Lipiodol TACE group (P=0.174). There was no statistically significant difference in AEs incidence among the two groups (P > 0.05). Conclusions: DEB-Lipiodol TACE was safe, well tolerated, and had a better efficacy compared with DEB-TACE in unresectable HCC patients.
