Bevacizumab: Patients were enrolled and given bevacizumab on days 1 and 15, administered by intravenous infusion at 5 mg/kg.
Study summary
Glioblastoma (GBM) usually grows in a diffuse fashion and infiltrates the surrounding brain. The inability to completely excise the tumor often leads to tumor recurrence within a few months of the initial surgery, which ultimately results in the death of the GBM patient.GBM histologically appears to be a tumor of vascular origin characterized by necrosis and microvascular proliferation, and neoangiogenesis is a key factor in the growth and poor prognosis of GBM. Bevacizumab can inhibit the biological effects of VEGF, including the permeability and proliferation of blood vessels, as well as the migration and survival of endothelial cells, so as to inhibit tumor angiogenesis, growth and metastasis. The aim of this study is to evaluate the efficacy and safety of bevacizumab in the preoperative adjuvant treatment of patients with new-onset high-grade gliomas.
