Through multicenter, open-label, randomised clinical trials, patients with resectable locally recurrent nasopharyngeal carcinoma are randomized into salvage surgery plus PD-1 treatment group and salvage surgery alone group. The efficacy and safety of patients between these two groups are compared.
Through multicenter, open-label, randomised clinical trials, we intend to demonstrate that PD-1 treatment added to salvage surgery could further decrease the rate of disease progression and improve the survival outcome of patients with resectable locally recurrent nasopharyngeal carcinoma compared with those treated with salvage surgery alone.
