Neoadjuvant vs Adjuvant in Locally Advanced Recurrent NPC

Neoadjuvant-Adjuvant Versus Adjuvant-Only Therapy Combined With Endoscopic Surgery in Advanced Recurrent Nasopharyngeal Carcinoma:A Multicenter Randomized Controlled Trial

A multicenter randomized controlled study of surgery combined with neoadjuvant and adjuvant therapy for locally advanced recurrent nasopharyngeal carcinoma in comparison to surgery combined with adjuvant therapy

Eligible patients are randomized into the control group and the experimental group.

Patients in the experimental group would be administrated 2 courses of neoadjuvant therapy before surgery.After endoscopic surgery, patients would continue to receive 2-4 courses of chemotherapy and 8 courses of immunotherapy.

Patients in the control group would firstly receive endoscopic surgery, followed by chemotherapy and immunotherapy. In total, 4 to 6 courses of chemotherapy and 10 courses of immunotherapy would be administrated.

Inclusion Criteria:

1. Pathologically diagnosed with recurrent nasopharyngeal carcinoma;
2. Resectable disease staging rT2 (deep parapharyngeal space, or distance to the internal carotid ≤5mm) or rT3 (excluding the lesions confined to the basal wall of sphenoid sinus), rT4, according to AJCC 8th edition;
3. Cervical lymph node metastasis can be controlled locally;
4. Aged 18 to 75 years;
5. Informed consent forms signed to participate in the trial;
6. Without distant metastasis;
7. ≥6months from the accomplishment of radical radiation to recurrence
8. previously only 1 course of radiotherapy;
9. Sufficient organ function;
10. ECOG score 0-2 and can tolerate surgery,chemotherapy and immunotherapy.

Exclusion Criteria:

1. Participate in other interventional clinical trials;
2. Uncontrolled illnesses that interfere with the therapy;
3. Suffering from another or multiple malignancy within 5 years (excluding fully treated basal cell or skin squamous cell carcinoma, cervical carcinoma in situ, etc.);
4. Any contradiction to surgery;
5. With serious autoimmune disease;
6. The patient is currently using immunosuppressive agents or systemic hormone therapy to achieve immunosuppressive effects (dosage>10mg/day prednisone or other glucocorticoids), and continues to use them within 2 weeks before the first administration;
7. Severe allergic reactions to other monoclonal antibodies;
8. History of radioactive particle planting;
9. Vaccination with live vaccine within 4 weeks prior to initial administration or possibly during the study period;
10. Female patients who are at pregnancy or lactation;
