PD-1 Antibody Combined With Chemoradiotherapy in Recurrent Nasopharyngeal Carcinoma Patients

Summary

This is a multicenter, randomized controlled, phase III clinical trial. The purpose of this study is to evaluate the efficacy and adverse effect of PD-1 antibody with chemoradiotherapy versus chemoradiotherapy alone in recurrent nasopharyngeal carcinoma patients.
