Following serum tumor makers were tested, including carbohydrate antigen-125 (CA-125):61.87 μl/ml (0.00–35.00 μl/ml), α-fetoprotein (AFP):9.40 ng/ml (0.00–7.00 ng/ml), carcinoembryonic antigen (CEA):1.61 ng/ml (0.00–4.30 ng/ml), human chorionic gonadotrophin:1.88 mIU/ml (0.00–3.00 mIU/ml). Here, CEACAM5 is linked to neoplasm.
