Background To evaluate the safety, treatment response, and overall survival (OS) following drug-eluting bead transarterial chemoembolization (DEB-TACE) using doxorubicin-loaded 40 μm microspheres in patients with advanced hepatocellular carcinoma (HCC). Methods This was a single-center retrospective evaluation of patients with unresectable HCC without extrahepatic spread and Barcelona Clinic Liver Cancer (BCLC) stages C and D disease who underwent DEB-TACE between August 2015 and January 2018. Pre-treatment data included demographics, medical history, cancer staging, tumor size, laboratory results, and prior treatments for HCC. Follow-up data included the date of DEB-TACE treatments or microwave ablation (MWA) procedures, laboratory test results, adverse events, treatment response, and the date and cause of death. Results Thirty-two patients met the study inclusion criteria. Eighteen patients (56.3%) underwent a single DEB-TACE and 14 patients (43.8%) had two to five DEB-TACE procedures. Five patients (15.6%) had MWA following initial DEB-TACE. Mild postembolization syndrome occurred in six patients (18.8%) during a 30-day period following initial DEB-TACE. Seven patients (21.9%) experienced worsening ascites, pleural fluid, or encephalopathy during the study observation period. Three patients had moderate to severe worsening liver function tests 90 days post-procedure. Seventeen patients (53.1%) had a complete or partial response and nine patients (28.1%) had disease progression. Median OS was 15.0±14.4 months from the time of initial DEB-TACE, with 63% and 33% of patients still alive at 12 and 24 months. Multivariate analyses identified that Okuda Stage (P=0.03) and Cancer of the Liver Italian Programme (CLIP) score (P=0.05) were significantly associated with overall survival after adjusting for other covariates. There were four HCC-related deaths during the 30-day post-procedure period. Conclusion DEB-TACE with small 40 μm doxorubicin-loaded microspheres is a safe and effective treatment for unresectable patients with BCLC stages C and D advanced HCC. Patients with advanced, high-risk unresectable HCC should be considered for DEB-TACE as opposed to supportive or palliative care alone. |
