Significance and Prognostic Value of The Coagulation Profile in Patients with Glioblastoma: Implications for Personalized Therapy
2019
Background Coagulation is an important aspect of the vascular microenvironment in which brain tumors evolve. Patients with tumor often show aberrant coagulation and fibrinolysis activation. In particular, glioblastoma (GBM), the most aggressive primary brain tumor, is associated with a state of hypercoagulability, and venous thromboembolism is a common complication of this cancer and its treatment. Our study aims to investigate the clinical and prognostic significance of routine laboratory tests to assess the coagulative state of patients with brain tumors, to identify potential new prognostic factors and targets for personalized therapy. Methods Blood samples were collected from patients with GBM ( n = 58) and patients with meningioma (MNG, n = 22), before any treatment. The parameters analyzed were prothrombin time (PT), activated partial thromboplastin time (aPTT), D dimer (DD), fibrinogen, von Willebrand factor (VWF), leukocyte count, and hemoglobin levels. Results Plasma levels of PT and aPTT were significantly reduced in GBMs compared with MNGs ( P P P Conclusions Our data support the assumption that patients with GBM show a plasma hypercoagulable profile and that coagulation profile is related to adverse outcome in patients with GBM. If confirmed, hypercoagulability could play an important role as a prognostic factor of the disease and in the decision of an antithrombotic prophylaxis.
