Trial Outcomes & Findings for Effect of Bevacizumab on Radiation-induced Brain Necrosis in Patients With Nasopharyngeal Carcinoma (NCT NCT01621880)

NCT ID: NCT01621880

Last Updated: 2019-01-09

Results Overview

The primary outcome of the trial was the treatment response rate at two months. The definitions of response and progressive disease were based on both the radiographic changes and clinical symptoms. We defined response as both (1)a reduction in edema volume on FLAIR images by ≥25% and (2)no deteriorating symptoms. Progressive disease was defined as either (1)larger than 10% increase in the volume of the lesions; (2)appearance of any new lesion/site; or (3)clear clinical worsening.

Corticosteroid
Patients in the corticosteroid group were treated with methylprednisolone 500 mg daily intravenously for three consecutive days followed by oral prednisone 60 mg for five days and gradually tapered 15mg every 5 days. When the prednisone dose reached 30mg per day, it was tapered down more slowly (tapered 5mg every week), until a maintenance dose of 10mg per day was reached. The entire intervention lasted two months. At 2 months, prednisone was stopped. Corticosteroid: Patients in the corticosteroid group were treated with intravenous pulsed-steroid therapy: methylprednisolone 500 mg daily intravenously for three consecutive days followed by oral prednisone 60 mg for five days and gradually tapered 15mg every 5 days.

SECONDARY outcome

Timeframe: Change from baseline to evaluation at 2 months.

T1 post-gadolinium imaging was used to measure the enhancement and T2-weighted FLAIR to measure the edema. For lesion measurements, radiologists used manual and semiautomatic approaches to identify the outline of the lesion, and the total volume was estimated with Volume Viewer 2 software(GE Healthcare, AW Suite2.0 6.5.1.z).
