Percentages are expressed as a ratio of the 50 patients investigated for the considered parameter. Tumor architecture and grading (G1–G4) were defined according to established classifications^50,51. Mean values are presented with ±standard deviation (s.d.). AFP, alpha-fetoprotein; HBsAg, HBV surface antigen; HCV, hepatitis C virus; n/a, not applicable.
