Investigators target recurrent nasopharyngeal carcinoma that can be resected surgically: rT1, rT2 (tumor confined to the surface of the parapharyngeal space, greater than 0.5cm from the internal carotid artery), rT3 (confined to the floor of the sphenoid sinus, greater than 0.5cm from the internal carotid artery/cavernous sinus) (AJCC 8th stage), A single-arm, phase II clinical trial was designed to investigate the efficacy and safety of triplizumab combined with nituzumab in induction and adjuvant treatment of operable local recurrent nasopharyngeal carcinoma.

The investigators focus on the 2-year PFS as the primary outcome.

Inclusion Criteria:

Recurrent nasopharyngeal carcinoma that can be resectable: rT1, rT2 (the tumor is confined to the surface of the parapharyngeal space, and the distance from the internal carotid artery is greater than that from the internal carotid artery 0.5cm), rT3 (confined to the floor wall of the sphenoid sinus, greater than 0.5cm from the internal carotid artery/cavernous sinus) (AJCC 8th stage).

If the tumor invades the internal carotid artery, or is less than 0.5cm away from the internal carotid artery, but the invasion scope does not exceed the external edge of the internal carotid artery, it can be advanced Internal carotid artery preconditioning (including internal carotid artery embolization or stent implantation) was followed.
