BACKGROUND/AIM: The outcome of hepatectomy for a hepatocellular carcinoma (HCC) exceeding 10 cm (i.e., huge HCC) remains unfavorable. The aim of the current study was to evaluate the optimal therapeutic approach for huge HCCs. PATIENTS AND METHODS: Between 2008 and 2018, patients with a huge HCC who underwent treatment at our institution were enrolled. Cases not meeting the criteria (Child-Pugh grade A or performance status 0/1) and patients with distant metastases were excluded. Patients were stratified into three groups: a) upfront hepatectomy (Upfront); b) hepatectomy subsequent to hepatic arterial infusion chemotherapy (HAIC-Hr); and c) HAIC alone (HAIC). Survival rates, including overall survival (OS) and progression-free survival (PFS), were analyzed. The cancer-specific mortality attributed to recurrence within one year after surgery was defined as "futile surgery"; the rate of futile surgery was also assessed. RESULTS: A total of 70 cases were censored (Upfront/HAIC-Hr/HAIC: 28/13/29). The 5-year PFS and OS rates for Upfront, HAIC-Hr, and HAIC were 7.7%, 69.2%, and 6.9%, and 37.1%, 79.1%, and 19.7%, respectively. The number of futile surgeries was 6 (21.4%) in the Upfront group, whereas no such cases occurred in the HAIC-Hr group. CONCLUSION: Although hepatectomy was advocated in the Upfront group due to the potential resectability, the outcomes were comparable to those of the HAIC group. Conversely, the HAIC-Hr group had promising outcomes, marked by a decreased prevalence of futile surgeries. Huge HCCs should be regarded as borderline resectable, even when deemed potentially resectable. Therefore, a multidisciplinary therapeutic approach might be reasonable.
