About this study

In order to further verify the effectiveness of the new prevention irradiation model for low-risk areas for nasopharyngeal carcinoma under immunotherapy, our team intends to conduct a non-inferiority clinical trial. The aim is to evaluate the efficacy and safety of two treatment modalities - local region reduced-target radiotherapy versus full-target radiatiotherapy (with/without CTV2) for newly diagnosed distant metastasis nasopharyngeal carcinoma, based on the full-course immunotherapy and full-dose chemotherapy. The primary endpoints are 2-year PFS and the incidence of grade 3 or higher radiation-related adverse events. If non-inferiority is confirmed, a new standard of "immunotherapy combined with reduced-target radiotherapy" will be established, ensuring efficacy while significantly reducing toxicity, and providing a more optimal comprehensive treatment strategy for nasopharyngeal carcinoma.
