Abstract:
Objective To explore the diffusion pattern of tumor markers (TM) from serum to cerebrospinal fluid (CSF) via the blood-brain barrier in patients with elevated serum tumor markers (TM).Methods Inpatients receiving lumbar puncture during hospitalization in our center from January 1, 2013 to December 31, 2015 were divided into study group (n=181) and control group (n=251). The study group consisted of patients with elevated serum TMs but without malignant central nervous system diseases. The control group consisted of patients with normal serum TM levels and without malignant diseases. TMs measured in the study group included elevated serum alpha-fetoprotein (AFP) (n=0), carcinoembryonic antigen (CEA) (n=26), carcinomic antigen(CA)125 (n=39), CA15- 3 (n=3),CA19- 9 (n=19), CA724 (n=47), CYFRA21- 1 (n=49), and SCC (n=17).Levels of TMs in the CSF of study group was compared with that of control group.Results Median CEA (U=0.00,P=0.00),CA19- 9 (U=0.00,P=0.00),CA15- 3 (U=0.00,P=0.04),SCC (U=0.00,P=0.00),CA125 (U=0.00,P=0.00),CA72- 4 (U=3.00,P=0.00)),and CYFRA21- 1 (U=0.00,P=0.00) in CSF were significantly lower than the corresponding serum TM levels in the study group.There was no significant difference between study group and control group for the CSF level of CEA (U=3091.00,P=0.18),CA19- 9 (U=1897.00,P=0.14), CA15- 3 (U=373.50,P=0.91)and SCC (U=1925.50,P=0.76). CSF CA125 (U=2188.00,P=0.00) and CA724 (U=1279.00,P=0.00) levels in the study group were lower than those in control group. CSF level of CYFRA21- 1 (U=1826.50,P=0.00) in study group was higher than that in control group;however, it was still lower than the upper limit of reference value. Conclusion In patients with elevated serum CEA, CA19- 9, CA15- 3, SCC, CA125, and CA72- 4 levels, transblood-brain-barrier diffusion of TMs from serum to CSF is highly unlikely.
