Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Bevacizumab is a recombinant humanized monoclonal antibody against vascular endothelial growth factor, which can improve the efficacy of cranial radiotherapy by normalizing neovascularization and improving the hypoxic state of tumor cells. In addition, bevacizumab can improve the abnormal permeability of neovascularization, reduce exudation and extracellular brain edema, thereby further alleviating the toxic side effects associated with brain radiotherapy.
Based on this, this prospective, controlled phase III study will explore the efficacy and safety of the combined use of fractionated stereotactic radiotherapy and bevacizumab in multiple brain metastases of lung adenocarcinoma.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Patients will be randomly assigned to three groups in a ratio of 1:1:1. The FSRT+beva group receives FSRT radiotherapy+bevacizumab treatment; FSRT targets visible intracranial lesions with a total dose of 30Gy, administered once a day for a total of 5 days, with a fraction dose of 6Gy. Bevacizumab starts on day 1 (one week before FSRT treatment), q3w， A total of 4 treatment courses, intravenous injection, with a dose of 7.5mg/kg. The FSRT group receives simple FSRT radiotherapy; FSRT is targeted at visible intracranial lesions, with a total dose of 30Gy, administered once a day for a total of 5 days, and a fraction dose of 6Gy for segmentation. The WBRT group receives whole-brain radiotherapy (WBRT) with a simultaneous integrated boost (SIB) to visible intracranial lesions. The prescribed doses are: 40 Gy total to gross lesions and 25 Gy total to the whole brain, delivered in 10 daily fractions.
