Gender	Male and Female
Key inclusion criteria	1) It has been diagnosed as non-small cell lung cancer with strong probability in the clinical diagnosis. 2) CT-solid tumor and tumor diameter >2.1cm or CEA>7.5 ng/ml or SUVmax>2.9 3) The age of registration is 20 years old or older and 85 years old or younger. 4) Ecog performance status 0 or 1. 5) No history of chemotherapy or radiation therapy for the chest, including treatment for other cancer species. However, the history of hormonal therapy is acceptable. 6) Complete all of the following with the test results within 30 days before the registration date. WBC>3,000/mm3,<12,000/mm3 Hb<9.0g/dl, Platelet count>10x104 /mm3, AST<100IU/L, ALT<100IU/L Total bilirubin<1.5mg/dL Serum creatinine<1.5mg/dL 7) A case in which the patient's consent is written about the participation of this study
Key exclusion criteria	1) Active malignant tumors (simultaneous malignant tumors and hesichotic malignancies with a disease-free period of less than 5 years). However, lesions equivalent to Carcinoma in situ (intraepithelial cancer) and intramucosal cancer, which are judged to be cured by topical treatment, are not included in active malignant tumors). 2) Patients with infectious diseases requiring systemic treatment, including HIV, HBV, and HCV infections. 3) Without using an antipyretic, there is a fever of 38 centi digree or more at axillary temperature within 24 hours before registration. 4) Continuous systemic administration (internal or intravenous) of steroids or other immunosuppressants. 5) Cases in which the attending physician deems it inappropriate to carry out this study
