In this exploratory clinical trial, patients with newly diagnosed distant metastatic nasopharyngeal carcinoma were treated with gemcitabine+ cisplatin+PD-1 inhibitor regimen followed by whole-target radiotherapy (IMRT for local regional lesion, SBRT for distant metastasis) and PD-1 inhibitor long-term maintenance regimen. To investigate the efficacy and safety of "whole target" radiotherapy combined with immuno-maintenance therapy.


This exploratory clinical trial will evaluate tumor control rate, survival, and safety of newly diagnosed distant metastatic nasopharyngeal carcinoma by further adding local regional IMRT, distant metastatic SBRT and immuno-maintenance therapy to the standard regimen of gemcitabine+ cisplatin+ PD-1 inhibitor (historical data). To explore whether the "full target" model can be a better comprehensive therapy for the initial diagnosed distant metastatic nasopharyngeal carcinoma in the era of immunotherapy.
