Efficacy and Safety ofToripalimab Combined With AP-induced Chemotherapyfollowed by Concurrent Chemoradiotherapy and Toripalimab-maintenance Therapysequentially in Patients With Non-metastatic IVB Hypopharyngeal Cancer : Aopen-lablc, Single-arm ,Phase II Clinical Study
Objective: to explore the relationship between the biomarkers in tumor tissue and / or blood, including PD-L1 (CPS/TPS), HPV (P16), PD-1, TMB, EGFR, CD3, CD4, CD8, TP53, MSI-H and the efficacy of immunotherapy, and the relationship between MDM2/MDM4, EGFR, chromosome 11q13 interval (CCND1/FGF19/FGF3/FGF4) and immune hyperprogression\] Participants will \[be treated with Toripalimab injection (240mg/, once every 3 weeks) combined with cisplatin / nedaplatin (40mg) and albumin paclitaxel (230mg/m2, once every 3 weeks). The efficacy was evaluated within 1 week after induction therapy. In the phase of simultaneous radiotherapy, albumin paclitaxel (230mg/m2, once every 3 weeks, D1/D21/D43) was used. One month after the end of synchronous radiotherapy and chemotherapy, the efficacy was evaluated. After evaluation, all patients entered the next stage of immune maintenance therapy. During the maintenance phase, Toripalimabv injection (240mg/, once every 3 weeks) was given for 6 months or until the disease progressed, the toxicity was intolerable, the subjects asked to withdraw voluntarily, and the researchers judged that the subjects needed to withdraw from the study. The patients were treated with spiral tomographic radiotherapy (TOMO) or intensity modulated radiotherapy (IMRT).. These patients were given Nimotuzumab injection at the same time during simultaneous radiotherapy and chemotherapy.

• The functional level of major organs conforms to the following criteria: 1) the standard of blood routine examination should meet the following criteria: WBC ≥ 3.0x109, G-CSF and other hematopoietic stimulating factors. 2) biochemical tests should meet the following criteria: TBIL ≤ 2.0 × ULN,ALT, AST ≤ 2.5 × ULN,BUN and CRE ≤ 1.5 × ULN or endogenous creatinine clearance ≥ 60ml/min (Cockcroft-Gault formula); 3) good coagulation function: defined as international standardized ratio (INR) or prothrombin time (PT) ≤ 1.5 times ULN; if the subject is receiving anticoagulant therapy, as long as PT is within the range of anticoagulant use. 4) Myocardial zymogram is within the range of normal value;
• Women of childbearing age must have taken reliable contraceptive measures, or conducted pregnancy tests (serum or urine) within 7 days before admission, and the results were negative, and were willing to use effective methods of contraception during the trial period and within 2 months after the last administration of anti-PD-1 antibody. For male subjects whose partners are women of childbearing age, effective methods of contraception should be used during the trial and within 2 months after the last administration of anti-PD-1 antibody. 8. The subjects voluntarily joined the study, signed the informed consent form, had good compliance and cooperated with follow-up.
