Randomized phase III trial of edatrexate versus methotrexate in patients with metastatic and/or recurrent squamous cell carcinoma of the head and neck: a European Organization for Research and Treatment of Cancer Head and Neck Cancer Cooperative Group study.

Abstract

Both EDX and MTX are moderately active against SCC. In this large phase III study, response rates, time to treatment failure, and overall survival appeared to be similar for both antifolates. However, EDX had more side effects than MTX and therefore cannot be recommended for routine palliative treatment of patients with SCC.
