When patients have multiple brain metastases or larger tumors (diameter\\>2cm), single session stereotactic radiotherapy (SRS) may cause significant neurological damage, so fractionated stereotactic radiotherapy (FSRT) is often used. The recent objective remission rate of FSRT is about 50%, and the 1-year intracranial control rate is about 45%, but intracranial progression remains the main factor affecting long-term survival of patients.\n\nBevacizumab 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.\n\nBased 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.",[88],"Multiple Brain Metastases in Lung Adenocarcinoma","2025-11-24",{"date":91,"type":92},"2025-12-02","ACTUAL",{"date":94,"type":92},"2025-06-30",{"date":96,"type":82},"2028-12-30",{"name":70,"class":6},1]
