Abstract
To determine medical reference values for tumor markers in cerebrospinal fluid. Concentrations of CEA, CA125, CA15-3, CA19-9, CA72-4, CYFRA21-1, AFP, NSE, SCC and HCG were determined by means of double-antibody sandwich ELISA in 110 patients excluding primary tumors and meningeal carcinomatosis using Roche E170 modular immunoassay analyzer. The determined medical reference values for tumor biomarkers in cerebrospinal fluid were as follows: CEA<0.573 microg/L, CA125<2.591 U/ml, CA15-3<2.045 U/ml, CA19-9<2.272 U/ml, CA72-4<1.252 U/ml, CYFRA21-1<1.44 ng/ml, AFP<0.968 microg/L, NSE<57.666 ng/ml, SCC<0.5 microg/L, HCG<0.769 U/L. There was no correlation between any tumor marker and age (P>0.05). Concentrations of tumor markers were not affected by gender (P>0.05). Medical reference values for CEA, CA125, CA15-3, CA19-9, CA72-4, CYFRA21-1, AFP, NSE, SCC and HCG in cerebrospinal fluid were first determined.
