Inclusion Criteria: * Patients volunteered to participate in the study and signed the informed consent. * Age 18-80, both male and female. * Histologically or cytologically confirmed squamous lung cancer staging T3-4, Nany, and M0 (according to the American Joint Committee on Cancer Staging (AJCC) 2017 Edition 8 TNM Staging System). Central-type classified according to chest imaging or bronchoscopy. * At least one measurable lesion according to RECIST 1.1. * ECOG PS 0-1. * Expected survival ≥ 6 months. * Patients who never received systemic therapy in the past, including radiotherapy, chemotherapy, targeted therapy and immunotherapy, or patients who relapsed more than 6 months after adjuvant chemotherapy. * The main organ functions accorded with the following criteria within 7 days before treatment: 1. Blood routine examination ( without blood transfusion in 14 days): hemoglobin (HB) ≥ 90 g/L; neutrophil absolute value (ANC) ≥ 1.5 \*109/L; platelet (PLT) ≥80 \*109/L. 2. Biochemical tests should meet the following criteria: 1) total bilirubin (TBIL) ≤1.5 times of upper limit of normal (ULN); 2) alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 \*ULN, if accompanied by liver metastasis, ALT and AST ≤ 5\* ULN; 3) serum creatinine (Cr) ≤ 1.5\* ULN or creatinine clearance rate (CCr) ≥ 60 ml/min;4) Serum albumin (≥35g/L). (3) Doppler echocardiography: left ventricular ejection fraction (LVEF) ≥the low limit of normal value (50%). * Tissue samples should be provided for biomarker analysis (such as PD-L1) Patients who could not provide new tissues could provide 5-8 paraffin sections of 3-5 μm by archival preservation. Blood sample should be collected at a pre-specified time point to complete the continuous dynamic MRD analysis. (non-mandatory). Exclusion Criteria: * Severe allergic reactions to humanized antibodies or fusion proteins in the past. * Severe allergic reactions to component contained in contrast agent or granule embolism agent in the past. * Metastasis to bone, brain, liver, pleural cavity, or any other distant organs. * Diagnosed of immunodeficiency or received systemic glucocorticoid therapy or any other form of immunosuppressive therapy within 14 days before the study, allowing physiological doses of glucocorticoids (≤10mg/day prednisone or equivalent). * Patients with active, known or suspected autoimmune diseases. Patients with type I diabetes, hypothyroidism requiring hormone replacement therapy, skin disorders requiring no systemic treatment (such as vitiligo, psoriasis or alopecia). Patients who would not triggers can be included. * Serious heart disease, include congestive heart failure, uncontrollable high-risk arrhythmia, unstable angina pectoris, myocardial infarction, and severe valvular disease. * Patients received systemic antineoplastic therapy, including cytotoxic therapy, signal transduction inhibitors, immunotherapy (or mitomycin C within 6 weeks before the grouping),recieved over-extended-field radiotherapy (EF-RT) within 4 weeks before the grouping or limited-field radiotherapy to evaluate the tumor lesions within 2 weeks before the grouping. * Positive hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus antibody (HCV Ab), indicating acute or chronic infection. * Patients with active pulmonary tuberculosis (TB) infection judged by chest X-ray examination, sputum examination and clinical physical examination. Patients with active pulmonary tuberculosis infection in the previous year should be excluded even if they have been treated; Patients with active pulmonary tuberculosis infection more than a year ago should also be excluded unless the course and type of antituberculosis treatment previously were appropriate. * Patients with brain metastases with symptoms or symptoms controlling less than 2 months.
