Abstract:
Objective To evaluate the serum changes in glioma patients, and in relations with clinicopathalogy parameters response to treatment and survival in patients with glioma via the examination of the significance of serum VEGF, Flt-1 and KDR levels. Methods Serum VEGF,Flt-1 and KDR levels were analyzed in patients of glioma before and after treatment, and patients with brain metastasis, as well as in healthy controls. Serum VEGF, Flt-1 and KDR levels were assessed by Enzyme-Linked Immunosorbent Assay(ELISA) and the data were processed by SPSS 11.5 for t-test and relevant analyses. Results Serum VEGF, Flt-1 and KDR levels were higher in patients with glioma than in healthy control (P =0.001, P =0.043 and P =0.045 respectively). Significant difference on levels of VEGF was found (P =0.032) comparing glioma group with brain metastasis group. The pretherapeutic serum levels of VEGF and Flt-1 were significantly different with disease recurrence or persistence after treatment (P =0.026 and P =0.038). There was significant correlation between the serum levels of VEGF correlated and that of Flt-1 and KDR (r =0.456 P
