Summary

The investigators plan to conduct a multicenter, prospective, single-arm phase II clinical trial of PD-1 monoclonal antibody combined with gemcitabine and cisplatin followed by selective radiotherapy for unresectable locally recurrent nasopharyngeal carcinoma to evaluate the efficacy and safety of PD-1 antibody plus GP chemotherapy followed by sequential selective radiotherapy in patients with unresectable locally recurrent disease who achieve tumor regression after immunochemotherapy, thereby providing evidence-based medical evidence for the treatment of unresectable locally recurrent NPC and improving treatment outcomes for these patients.

Conditions

  • Nasopharyngeal Cancinoma (NPC)

Interventions

DRUG

PD-1 monoclonal antibody combined with gemcitabine and cisplatin followed by selective radiotherapy

1. Gemcitabine + Cisplatin Chemotherapy: Gemcitabine 1000 mg/m² on days 1 and 8 + Cisplatin 80 mg/m² on day 1, every 3 weeks, for 4-6 cycles. PD-1 Monoclonal Antibody Immunotherapy: Toripalimab 240 mg on day 1, every 3 weeks, or Tislelizumab 200 mg on day 1, every 3 weeks, or Camrelizumab 200 mg on day 1, every 3 weeks, for 4-6 cycles. 2. PD-1 Maintenance Therapy: Toripalimab 240 mg on day 1, every 3 weeks, or Tislelizumab 200 mg on day 1, every 3 weeks, or Camrelizumab 200 mg on day 1, every 3 weeks, until disease progression (according to RECIST v1.1; if progression occurs in the nasopharynx or neck while metastatic lesions remain well controlled, radiotherapy to the nasopharynx and neck will be given, after which immunotherapy maintenance may continue until further progression), unacceptable toxicity, withdrawal of patient consent, or completion of a cumulative 2 years of treatment.
