Does the margin width influence recurrence rate in liver surgery for hepatocellular carcinoma smaller than 5 cm?

5-10 mm surgical resection margin for HCC smaller than 5 cm seems to be safe as a wider surgical margin because does not increase the risk of marginal recurrence and does not decrease overall survival rate. Further prospective and randomized studies are required to definitively clarify the importance of surgical margin width in hepatic resection for HCC.
