Clinical outcomes of DEB-TACE in locally advanced hepatocellular carcinoma: A 5-year real world experience.

Purpose: To evaluate outcomes including safety and efficacy of drug-eluting bead trans-arterial chemo-embolization (DEB-TACE) in the treatment of locally advanced hepatocellular carcinoma (LA-HCC). Materials and methods: In this single-center, retrospective study, we evaluated 471 consecutive patients with LA-HCC who underwent DEB-TACE from 2015 to 2020. Efficacy of DEB-TACE was assessed based on the imaging response using the modified Response Evaluation Criteria in Solid Tumors (mRECIST) and the biochemical response using alpha-fetoprotein (AFP) levels at 1-month follow-up. Adverse events, progression free survival (PFS), and overall survival were also examined. Results: HCC distribution was bilobar in 49% with largest lesion mean size of 4.3 cm ± 3.2, and a majority of patients (46.7%) were Barcelona Club Liver Cancer (BCLC) stage B. Complete radiologic response was achieved in 120 (25.5%) patients, comparable to a reported 28% rate for conventional TACE. Biochemically, 41 (8.7%) patients achieved complete response, and 113 (24%) had a partial response. A total of 59 (12.5%) patients were successfully bridged to liver transplantation. Major adverse events were observed in 3%, while 7.2% experienced post-embolization syndrome. Mean PFS was 6.7 months ± 6.6, and overall survival was 64%, 16.3%, 2.1% at 1, 3, and 5 years, respectively. Conclusion: Based on our real world experience at a single center, DEB-TACE remains the locoregional therapy of choice for LA-HCC due to its favorable safety and efficacy profile.
