Risk Factors for Beyond Milan Recurrence After Hepatic Resection for Single Hepatocellular Carcinoma No Larger Than 5 Centimeters

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
