“…Previous studies have identified various risk factors for early and late recurrence in patients with HCC. Early recurrence after resection for HCC is likely to be associated with aggressive tumor biology , especially macro or microscopic vascular infiltration (Portolani et al, 2006;Wu et al, 2009), whereas late recurrence is likely to be associated with the presence of cirrhosis (Poon et al, 2000;Portolani et al, 2006) and hepatitis virus infection (Wu et al, 2009;Muscari et al, 2011). Most of the them were performed in unselected patients ,including patients with macrovascular invasion and/or multiple tumors.…”
