This paper retrospectively analyzed the diagnosis and treatment process of a patient with advanced nasopharyngeal carcinoma(NPC)accompanied by multiple liver,lung,and lymph node metastases.The patient underwent camrelizumab immunotherapy in conjunction with chemotherapy,and demonstrated positive efficacy with a progression-free survival of 55 months.Despite a 5-month interruption in immunotherapy treatment caused by the CO VID-19 epidemic,the patient's tumor remained well controlled with no apparent signs of recurrence or metastasis.Throughout the treatment,there were no grade 3-4 treatment-related side effects,and the patient's quality of life remained good.Immunotherapy combined with chemotherapy can bring significant survival benefits to patients with the recurrent/metastatic NPC.
