Cerebrospinal Fluid Sialic Acid / Total Protein Ratio As A Tumor Marker in Brain Tumors
1Akdeniz Üniversitesi Tıp Fakültesi, Biyokimya Anabilim Dalı, Kepez. Antalya2Akdeniz Üniversitesi Tıp Fakültesi, Nöroşirürji Anabilim Dalı, Kepez. Antalya Serum and cerebrospinal fluid (CSF) sialic add concentrations and sialic add / total protein (SA/TP) ratios were analyzed in the patients with brain tumors and compared with control.
It was found in increased levels in the patients with grade I-II (n= 12) and grade III-IV tumors (n = 19), but serum and CSF levels of Sialic add in grade I-II and grade III-IV tumor patients were not found significantly different. CSF SA/TP ratios increased in grade I-II and grade III-IV tumor patients and also SA/TP ratios were significantly higher in grade III-IV than the ration in grade I-II (p< 0.01). So, SA/TP ration in CSF exists a more reliable marker which reflects the grade of brain tumors when compared to serum and CSF sialic add levels.
