Tumor marker detection showed serum alpha-fetoprotein (AFP) level (1.86ng/ml), carbohydrate antigen 125 (CA125) level (11.30U/ml), carbohydrate antigen 19 − 9 (CA19-9) level (10.9U/ml), and carcinoembryonic antigen (CEA) level (3.23ng/ml), which were no obvious abnormalities. This evidence concerns the gene CEACAM5 and neoplasm.
