Usefulness of Thromboelastography as a Predictor of Prognosis in Patients Undergoing Surgery for Glial Tumors and of the Risk of Postoperative Thromboembolic Disease (GliTEM)

Fundacion Clinic per a la Recerca Biomédica100 enrolled

Overview

The objective of our study is to investigate the clinical significance of thromboelastometric values in the development of thrombotic events and survival in patients with glial tumors, to reduce thromboembolic complications and optimize oncological treatment.

The main hypothesis is Adult patients with glial tumors who present a pattern of hypercoagulability in laboratory parameters and/or thromboelastometry have a higher incidence of thromboembolic events and lower survival compared with patients without a hypercoagulability pattern.
