Brief Summary
The goal of this clinical trial is to compare efficacy of two different resection extension in patients with resectable recurrent nasopharyngeal carcinoma after induction chemotherapy. The main question it aims to answer is that whether tumor regress areas after induction chemotherapy required complete resection. Patients will be randomly assigned to receive reduced-target resection or full-target resection after induction chemotherapy. Researchers will compare these two groups to see if the efficacy of reduced-target resection is not inferior to full-target resection.

Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
Resectable nasopharyngeal diseases: recurrent T1 (the tumor is confined in nasopharynx, oropharynx and/or nasal cavity without parapharyngeal involvement); recurrent T2 (the tumor is confined in the superficial parapharyngeal spacer and is more than 0.5cm far from the internal carotid artery) and recurrent T3 (the tumor is confined in the base wall of the sphenoid sinus and is more than 0.5cm far from the internal carotid artery and cavernous sinus) (according to the 8th edition of American Joint Committee on Cancer (AJCC) staging system for nasopharyngeal carcinoma). If the tumor invaded the internal carotid artery, or the instance from the internal carotid artery was less than 0.5cm, but the invasion area did not exceed the external edge of the internal carotid artery, the patients could be enrolled after internal carotid artery pretreatment (including internal carotid artery embolization or stent implantation).
After 3 cycles induction chemotherapy (Platinum based chemotherapy \[gemcitabine/paclitaxel and platinum\] and immunotherapy\[PD-1/PD-L1 antibody\] or a GAP regmen\[gemcitabine, Apatinib and immunotherapy\[PD-1/PD-L1 antibody\]), patients achieved at least PR according to RECIST criteria, and the reduction of pSTV after induction chemotherapy more than 50%.
Given written informed consent.
You may not qualify if:
Karnofsky Performance Status (KPS) ≤70.
Has severe medical disorder, important organ dysfunction, and/or a substantial history of mental illness.
Tumor confined to the roof or the posterior wall of nasopharynx, without expected benefit from reduced-target resection.
Unresectable recurrent regional lymph node diseases (recurrent N1-3) with prevertebral fascia, cervical vertebrae, or common/internal carotid artery involvement (according to the 8th edition of AJCC staging system).
Clinically diagnosed with metastatic NPC.
Has known subjects with other malignant tumors (except for cured skin basal cell carcinoma or cervical carcinoma in situ).
Received a systematic or local glucocorticoid therapy within 4 weeks of planned start of study treatment.
Suffered from diseases need long-term treatment with immunosuppressive drugs, or required systematic or local glucocorticoid therapy with immunosuppressive doses.
Prior therapy with a PD-1, anti-PD-Ligand 1 (PD-L1) or cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) agent.
Has active autoimmune disease (e.g., uveitis, enteritis, hepatitis, hypophysitis, nephritis, vasculitis, hyperthyroidism, and asthma requiring bronchodilator therapy). Patients with skin disease that doesn't require systemic treatment (e.g., vitiligo, psoriasis, or alopecia) will be allowed to enroll.
