Brief summary: This is a prospective, single-arm, phase II clinical trial. The purpose of this study is to evaluate the efficacy and adverse effect of SBRT and LDRT combined with programmed death 1 (PD-1) antibody and chemotherapy in recurrent/metastatic nasopharyngeal carcinoma patients.


Eligibility criteria: Inclusion Criteria:

* No contraindications to immunotherapy and chemoradiotherapy;
* At least one lesion could receive SBRT safely;
* Subject must have a measurable target lesion based on RECIST v1.1;
* Adequate marrow function: WBC count ≥ 3×10E9/L, NE count ≥ 1.5×10E9/ L, HGB ≥ 90g/L, PLT count ≥ 100×10E9/L;
