Core Tip

Core Tip: The prognosis of anatomic resection is better than that of non-anatomic resection with diameters from 2 to 5 cm. For tumor diameters smaller than 2 cm and larger than 5 cm, anatomic resection is not superior to non-anatomic resection. Anatomic resection can achieve the removal of peritumoral microvascular invasion by obtaining a wide incision margin. Both anatomic resection and non-anatomic resection can obtain wide surgical margins in the group with tumor diameters smaller than 2 cm. Both anatomic resection and non-anatomic resection failed to obtain wide surgical margins in the diameter larger than 5 cm group.
