[The determination of medical reference values for tumor markers in cerebrospinal fluid].
摘要
OBJECTIVE: To determine medical reference values for tumor markers in cerebrospinal fluid. METHODS: 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. RESULTS: 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). CONCLUSION: 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.
