|
Objectives of Study: |
Through imaging studies and disease progression assessments, this study aims to explore and evaluate the efficacy of bevacizumab in treating postoperative radiation-induced cerebral edema in patients with brain metastases who have undergone gamma knife therapy. Assess the safety and tolerability of bevacizumab in the treatment of radiation-induced cerebral edema based on the incidence and severity of adverse events and serious adverse events, as well as other safety parameters (including vital signs, physical examination, 12-lead electrocardiogram (ECG), and laboratory tests). |
