Radiation-induced brain injury 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 treatment of bevacizumab followed by steroid can alleviate radiation-induced brain injury in patients with nasopharyngeal carcinoma, and to compare the treating effect between combination of bevacizumab and steroid and bevacizumab alone.
Treatment of bevacizumab followed by steroid may have a better effect on patients with radiation-induced brain injury.This randomized trial aims to investigate whether treatment of bevacizumab followed by steroid may alleviate radiation-induced brain injury in patients with nasopharyngeal carcinoma. The effect will be compared with outcomes in patients receiving steroid therapy
