Radiation-induced brain necrosis is a severe complication of radiotherapy in patients with Nasopharyngeal carcinoma. Current neuroprotective therapies show limited benefit in ameliorating this complication of radiotherapy. This study is a randomized, single blind clinical study. The primary aim of this study is to determine whether bevacizumab can alleviate radiation-induced brain necrosis in patients with nasopharyngeal carcinoma, and to compare the treating effect between bevacizumab and steroid.
Bevacizumab may have a better effect on brain necrosis caused by radiotherapy.This randomized trial aims to investigate whether bevacizumab may alleviate radiation-induced brain necrosis in patients with nasopharyngeal carcinoma. The effect will be compared with outcomes in patients receiving steroid therapy.
