RESUMO
PURPOSE: To investigate the potential safety and efficacy of drug-eluting bead-transcatheter arterial chemoembolization (DEB-TACE) in treating TACE-refractory hepatocellular carcinoma (HCC). METHODS: We retrospectively evaluated the treatment outcomes of DEB-TACE for 41 HCC nodules in 30 patients who were refractory to conventional TACE (c-TACE) according to tumor response. The antitumor response was evaluated according to mRECIST criteria, and changes in alpha-fetoprotein (AFP), albumin-bilirubin score, the incidence of adverse events, and the time to disease progression were observed. RESULTS: The objective response rate and disease control rates were 60.98% and 95.12% at 4 weeks after DEB-TACE, 63.41% and 92.68% at 8 weeks, respectively. The median time of disease progression was 4.60 ± 0.23 months. The AFP of patients decreased continuously at 2-6 weeks after operation, and the AFP at 4 weeks was significantly lower than that at 2 weeks (P = 0.038). Adverse reactions were well tolerated, and no grade 4 adverse reactions were reported. The albumin-bilirubin score did not deteriorate within 6 weeks. CONCLUSION: DEB-TACE has potential efficacy and safety after failure of c-TACE in patients with advanced liver cancer. Further studies are needed to confirm the efficacy of DEB-TACE treatment after failure of c-TACE.
