Background/Aim: For intermediate-stage hepatocellular carcinoma (HCC) (Barcelona Clinic Liver Cancer [BCLC]-B) cases, transarterial chemoembolization (TACE) is recognized as the standard treatment, while systemic therapy is recommended for TACE-unsuitable HCC. However, because the curative potential is not high, this study was conducted to elucidate the potential outcomes of surgical resection (SR) for BCLC-B HCC cases. Materials/Methods: From January 2000 to July 2022, 70 patients with BCLC-B HCC treated with surgery as the initial treatment were enrolled (median age 67.5 years, beyond up-to-7 criteria 44). Forty-five were treated with SR only (SR group), while twenty-five underwent that with complemental radiofrequency ablation (RFA) (Comb group). Recurrence-free survival (RFS) and overall survival (OS) were retrospectively evaluated in both groups. Results: The median albumin−bilirubin (ALBI) score was better in the SR as compared with the Comb group (−2.74 vs. −2.52, p = 0.02), while there were no significant differences between them for median RFS (17.7 vs. 13.1 months; p = 0.70) or median OS (66.6 vs. 72.0 months p = 0.54). As for those beyond up-to-7 criteria, there were no significant differences for median RFS (18.2 vs. 13.0 months; p = 0.36) or median OS (66.5 vs. 72.0 months; p = 0.57). An acceptable five-year cumulative survival rate (>50%) was obtained in both groups (54% vs. 64%). Conclusion: This retrospective study found no significant differences for RFS or OS between the present SR and Comb groups with BCLC-B HCC. When possible to perform, the outcome of SR for BCLC-B is favorable, with a five-year survival rate greater than 50%.
