Results of IVB tumor marker analyses were as follows: AFP (≤7.00 ng/ml, 110 patients; >7.00 ng/ml, 52 patients), CEA (≤5.20 ng/ml, 91 patients; >5.20 ng/ml, 71 patients), CA19-9 (≤27.00 U/ml, 71 patients; >27.00 U/ml, 91 patients), CA-125 (≤35.00 U/ml, 58 patients; >35.00 U/ml, 104 patients), and CA72-4 (≤6.90 U/ml, 44 patients; >6.90 U/ml, 118 patients). Here, AFP is linked to neoplasm.
