Background: Chemoembolization with small drug-eluting microspheres is widely used in the treatment of hepatocellular carcinoma (HCC). Objectives: This study aimed to evaluate the efficacy and safety of transarterial chemoembolization with doxorubicin-eluting 30-60-mu m microspheres (DEB-TACE) in patients with Barcelona Clinic Liver Cancer (BCLC) stage A and B HCC. Materials and methods: In this single-center study, 88 patients with HCC (BCLC A/B: 15.9%/84.1%) who underwent 137 DEB-TACE sessions between January 2015 and December 2020 were retrospectively assessed. Response to treatment was assessed 4-8 weeks after each DEB-TACE procedure according to mRECIST (Modified Response Evaluation Criteria in Solid Tumors) criteria. Progression-free survival (PFS), time to progression (TTP), overall survival (OS), and adverse events were recorded. Results: In 88 patients (84.1% males; median age, 66.0 years; range, 22-83), the median follow-up was 17 months (range, 2-64). Eight patients (9.1%) had a complete response, 42 (47.8%) had partial regression, 10 (11.3%) had stable disease, and 28 (31.8%) had progressive disease. There was a statistically significant difference between serum alpha-fetoprotein (AFP) levels before and after DEB-TACE treatment (p < 0.001). The median OS was 17 months (95% confidence interval [CI], 10.3-23.7). Cox regression analyses found that preprocedural serum AFP level (400+ vs. < 400; p = 0.024), Child Pugh classification (B vs. A; p = 0.019), and number of DEB-TACE sessions (1 vs. > 1; p = 0.003) were independent risk factors affecting OS. The median PFS was 8 months (95% CI, 5.8-10.2) and TTP was 6 months (1-14 months). Conclusion: Chemoembolization with 30-60-mu m microspheres is an effective and safe treatment for HCC. The number of DEB-TACE sessions is also one of the factors affecting OS.
