The concentrations of tumor markers such as carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 were normal, and the concentrations of arufa-fetoprotein (AFP) (217.2 ng/mL) and des-gamma-carboxy prothrombin (DCP) (1951 AU/mL) were elevated. This evidence concerns the gene CEACAM5 and neoplasm.
