Abstract:
Objective To analyze the expression changes of transforming growth factor-β (TGF-β) and vascular endothelial growth factor (VEGF) in malignant brain gliomas and their values in tumor resectability evaluation.Methods One hundred and eighty-eight patients with malignant brain gliomas received surgery in our hospital from January 2010 to January 2017 were chosen in our study as patient group;during the surgery,the glioma tissues and peritumoral tissues were collected;Westem blotting was employed to detect the VEGF and TGF-β expressions.Fifty healthy controls accepted healthy examinations at the same time-period were enrolled.Peripheral blood 24 h before surgery of the two groups was collected.ELISA was used to test the serum VEGF and TGF-β levels.The values of serum VEGF and TGF-β levels in tumor resectability were analyzed by receiver operating characteristic (ROC) curve.Results In the patient group,significantly higher levels of VEGF and TGF-β in the tumor tissues were noted as compared with those in the para-tumor tissues (P<0.05).Significantly higher levels of VEGF and TGF-β in the patient group were noted as compared with those in the control group (P<0.05).There were 126 patients received total tumor resection,while 62 just had partial tumor resection;one year after surgery,22 patients with total tumor resection (17.46%) died,and 20 patients with partial tumor resection (32.26%) died,which indicated that the cumulative mortality rate one year after surgery in patients with total tumor resection was significantly lower than that in patients with partial tumor resection (P<0.05).With cut-off point value of 588.0 pg/mL,ROC analysis showed that the sensitivity of VEGF in prediction of total tumor resection was 80.65%,and specificity 80.16%,and area under curve 0.82,which were better than those of TGF-β.Conclusion For malignant brain glioma patients,the levels of VEGF and TGF-β increase,and VEGF shows an ideal value in tumor resectability evaluation.
