Hepatic resection (HR) is considered a treatment of choice for a single hepatocellular carcinoma (HCC) ≤5 cm in patients with preserved liver function. However, it is possible for these patients to develop a severe form of recurrence (beyond Milan recurrence [BMR] criteria). This recurrence could have been avoided if liver transplantation (LT) was performed primarily, as LT is believed to yield a more favorable oncological outcome compared with HR. The aim of this study was to determine the risk factors for BMR after HR and to verify whether primary LT can provide a more favorable outcome in patients with BMR risk factors. Data from 493 patients who underwent HR for HCC ≤5 cm between 1995 and 2016 were analyzed. Among them, 74 patients (15%) experienced BMR. The 10‐year survival rate of patients with BMR was significantly low compared with that of patients without BMR (22.6% versus 79.8%; P < 0.01). In multivariate analysis, calculated hepatic venous pressure gradient ≥7 mm Hg and microvascular invasion were identified as the risk factors for BMR ( P < 0.05). During the same period, 63 eligible patients underwent LT as a primary treatment for HCC ≤5 cm. No significant difference in long‐term survival rate was observed when no risk factor for BMR was present in the HR and LT groups (85.5% versus 100%; P = 0.39). However, 10‐year survival was poorer in the HR group in the presence of risk factors for BMR (60.6% versus 91.8%; P < 0.001). Among the patients with HCCs ≤5 cm, which are resectable and transplantable, LT is indicated when calculated hepatic venous pressure gradient ≥7 mm Hg and/or microvascular invasion is present.
