The meaning of gross tumor type in the aspects of cytokeratin 19 expression and resection margin in patients with hepatocellular carcinoma

摘要

Background: There is no consensus on the safe resection margin in patients with hepatocellular carcinoma. Surgeons decide the extent of resection according to residual liver function and tumor location. We investigated the influence of resection margin on early recurrence with respect to gross tumor type and expression of cytokeratin 19 (CK19).
