Background/Aims: To retrospectively compare conventional and drug-eluting beads transarterial chemoembolization (C-TACE and DEB-TACE) for treatment of hepatocellular carcinoma (HCC) at very early and early stages.
Methods: We retrospectively compared patients treated with C-TACE (n=115) or DEB-TACE (n=103) from September 2009 to May 2016. All patients were in a very early (stage 0) or early stage (stage A) of the Barcelona Clinic Liver Cancer (BCLC) staging system, and all had Child? Pugh class A and ≤B7 liver status. Approval by the institutional review board was waived because the study was retrospective. The following parameters were evaluated: severe pain and bradycardia during TACE, post-embolization syndrome (PES), liver function change, complications, target tumor response, and conversion to another treatment modality. Numeric differences were assessed by the independent Student’s t-test for continuous variables and by chi-square test for categorical variables.
Results: Severe intractable pain and bradycardia during the TACE procedure were significantly more frequent in the C-TACE group than in the DEB-TACE group (P<0.001). The incidence and duration of PES were significantly higher in the C-TACE group than in the DEB-TACE group (P<0.001). The increase in liver enzymes was significantly higher in the C-TACE group than in the DEB-TACE group (P<0.001). The deterioration of the Child-Pugh class was significantly higher in the C-TACE group than in the DEB-TACE group (P =0.006). There was no significant difference in serious complications except localized bile duct dilatation between the groups. There was no significant difference between the groups in tumor response at both immediate and 1-year assessment. The conversion rate to other treatment modalities was significantly higher in the DEB-TACE group than in the C-TACE group (P<0.001).
Conclusions: DEB-TACE is better than C-TACE in terms of procedural safety as initial treatment in a very early or early stage of HCC.
