Core Tip

Core tip: Many papers have reported the relative outcomes between liver resection and radiofrequency ablation, but here we selected patients with small and single hepatocellular carcinoma (HCC) in the left lateral segments. The present study showed that the disease-free survival curve and the overall survival curve were higher in the left lateral sectionectomy (LLS) group than in the radiofrequency ablation (RFA) group for those patients. However, the hospital stay was longer for the LLS group than for the RFA group. We conclude that liver resection is suitable for single HCC ≤ 3 cm in the left lateral segments.
