The serum level of tumor marker including carcinoembryonic antigen and carbohydrate antigen 19-9 were 3.08 ng/mL and 0.6 U/mL, respectively.
The tumor markers carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9) are frequently elevated as well.
Serum levels of gamma-glutamyl transferase, aspartate transaminase, alanine transaminase, alpha-fetoprotein, carbohydrate antigen 19-9 and carcinoembryonic antigen were normal.

PHNECs = primary hepatic neuroendocrine carcinomas, ALT = alanine aminotransferase, AST = aspartate aminotransferase, HB = hemoglobin, ALP = alkaline phosphatase, GGT = y-glutamyl transpeptidase, CA19- 9 = carbohydrate antigen 19-9, HbsAg = hepatitis B virus surface antigen.
Level of tumor marker carbohydrate antigen 19-9 (CA 19-9) was 2792 kU/l, significantly exceeding the reference range (normal value <37-40 kU/l).
Serum concentrations of carbohydrate antigen 19-9 (CA19-9; orange line) and carcinoembryonic antigen (CEA; blue line) were high during chemotherapy but normalized dramatically after surgery, with no significant increase detected to date.
Levels of carcinoembryonic antigen were within normal range; that is, CEA levels were 1.43 ng/ml (normal values < 3 ng/ml) and carbohydrate antigen 19-9 (CA 19-9) levels were 6,4 U/ml (normal values < 37 U/ml).
Laboratory findings were as follows: total bilirubin, 3.31 mg/dL (normal range 0.3-1.2); serum alanine aminotransferase, 113 U/L (normal range 0-40); serum aspartate transaminase, 114 U/L (normal range 0-40); serum alkaline phosphates, 145 U/L (normal range 40-129); serum carcinoembryonic antigen (CEA), 2.8 ng/mL (normal range < 5.0 mg/mL); alpha-fetoprotein (AFP), 0.7 ng/mL (normal range < 9.6 ng-mL); and serum carbohydrate antigen 19-9 (CA 19-9), 42.2 U/mL (normal range < 39 U/mL).
Laboratory tests showed elevated serum total bilirubin (5.1mg/dL), alpha-fetoprotein (182.7 ng/mL), and carbohydrate antigen 19-9 (70.5 U/mL) levels.
A 59-year-old woman presented with laboratory data comprising carcinoembryonic antigen, 5.13 ng/ml; carbohydrate antigen 19-9 (CA19-9), 149.90 U/ml; serum IgG4, 3.21 g/L; and total bilirubin, 354.90 [micro]mol/L.
