Conventional Versus Small Doxorubicin-eluting Bead Transcatheter Arterial Chemoembolization for Treating Barcelona Clinic Liver Cancer Stage 0/A Hepatocellular Carcinoma

Purpose Approximately, 60–70% of patients with early-stage hepatocellular carcinoma (HCC) globally are ineligible for the recommended first-line procedures. This study aimed to compare conventional transcatheter arterial chemoembolization (cTACE) with a treatment, small drug-eluting bead TACE (DEB-TACE), in patients with stage 0/A HCCs. Materials and Methods We retrospectively investigated 76 patients who underwent first-time cTACE ( n = 40) or DEB-TACE using 75–150 µm DC Beads ® ( n = 36) for Barcelona Clinic Liver Cancer (BCLC) stage 0/A HCC 0.05). Complete and partial 1-month tumor response rates were 60.0% and 22.5%, respectively, in the cTACE group and 69.4% and 25.0%, respectively, in the DEB-TACE group. The abdominal pain grade was significantly lower with DEB-TACE than with cTACE ( p = 0.001). AST and ALT levels after tumor treatment with DEB-TACE were significantly lower than those after treatment with cTACE ( p = 0.018 and 0.006). Time to local progression, intrahepatic distal recurrence, progression-free survival, and overall survival were not significantly between the DEB-TACE group and the cTACE group ( p > 0.05). Conclusion Time to local progression between groups was not significantly different; however, post-embolic syndrome occurred less frequently in the DEB-TACE group. DEB-TACE appears to be a feasible treatment for small HCCs. Level of Evidence Level 3.
