This Phase II randomized study is to determine the efficacy and safety of Bevacizumab combined with fractionated stereotactic radiation therapy(FSRT) in patients with 1 to 10 brain metastases in non-small cell lung cancer by assessing the treatment response, neurological symptoms and quality of life.
Patients will receive Bevacizumab(7.5mg/kg, q3w, i.v.) before and after FSRT(40Gy in 10 fractions or 30Gy in 5 fractions) to the brain metastases. The primary endpoint was intra-cranial progression-free survival (IPFS). Secondary endpoints included overall survival (OS), progression-free survival (PFS), quality of life (QOL) scores, and toxicities.
