regarding the primary lesion, meet one of the following on chest ct. i. direct invasion of the chest wall at or above the height of the first rib (at least invasion of the parietal pleura) ii. direct invasion of the subclavian artery or vein ii. regarding regional lymph nodes, meet either of the following by chest ct and fdg-pet/ct. metastasis is also considered if lymph node metastasis is determined by either chest ct or fdg-pet/ct. i. cn0 ii. cn1 and no metastases to #10, #11, and #12 lymph nodes iii. cn3 (ipsilateral supraclavicular lymph node metastasis) and no metastases in regional lymph nodes (n1 and n2) other than "#13, #14 lymph nodes" iii. no distant metastases (including intrapulmonary metastases in the same ling lobe and in a different lung lobe on the same side) on imaging tests including fdg-pet/ct 3. it is judged that radical resection is possible by lobectomy (including bilobectomy for 2 lobes), which satisfies the following \[1\] and \[2\]. i. the board respiratory surgeon judges that none of the following is true based on the image findings. i. there is vertebral body infiltration that requires total spondylectomy ii. presence of spinal cord infiltration iii. invaded trachea or tracheal bifurcation iv. invasion of aortic arch or ascending aorta v. invading brachial plexus at c8 or higher vi. esophageal infiltration that requires esophageal reconstruction for resection vii. pneumonectomy is required for radical resection ii. meet all of the following. i. predicted postoperative forced expiratory volume of 1 second (fev1.0) ≥ 800 ml within 56 days before registration ii. spo2 \> 93% (room air) with the latest inspection value within 14 days before registration 4. consult with the radiotherapy doctor and it is judged that all of the following are met. i. radiation therapy is possible according to the protocol ii. the irradiation field does not reach the hilum 5. the age of the registration date is 20 years or older and 75 years or yonger. 6. performance status (ps) is 0 or 1 according to ecog standards (ps must be described in medical records) 7. the presence or absence of measurable lesions is not required. 8. no history of following surgery irrespective of whether for a benign or malignant lesion. i. thoracoscopic surgery or thoracotomy with excision of the affected lung or esophagus or mediastinum (however, a history of thoracoscopic surgery without wedge resection or lung, esophagus, or mediastinal resection (eg, pleural biopsy)) is allowed) ii. median sternotomy surgery (with or without organ resection) iii. pulmonary resection other than wedge resection of the contralateral lung (whether open-heart surgery or thoracoscopic surgery) 9. there is no history of chemotherapy, including treatment for other cancer types (including molecular targeted therapies and immune checkpoint inhibitors). however, the history of drug therapy as adjuvant therapy is allowed if it was completed more than 3 years ago. in addition, a history of hormone therapy for other cancer types is allowed. 10. if there is a history of radiotherapy including other cancer types, the lung, hilum, mediastinum, and supraclavicular fossa are not included in the irradiation field. 11. chest ct does not show interstitial pneumonia or pulmonary fibrosis. 12. no history of complication of autoimmune disease or chronic or recurrent autoimmune disease. however, patients with type 1 diabetes which is well controlled by appropriate treatment, hyperthyroidism/hypothyroidism that requires only antithyroid drug/hormone replacement therapy, autoimmune skin disease that does not require systemic treatment (pemphigus, psoriasis vulgaris, pemphigus vulgaris, vitiligo), and celiac disease controlled only by dietary control are regarded as eligible if they have been inactive in the past 5 years, even with a history of autoimmune complications or history. 13. no surgical treatment with general anesthesia within 14 days (2 weeks) before registration. 14. no systemic administration of steroids, other immunosuppressive drugs, or immunoglobulins within 28 days (4 weeks) before registration. however, those that meet the following conditions are allowed. i. intranasal/inhalation/topical steroid injection or local steroid injection (for example, intra-articular injection) ii. systemic administration of steroid drugs at a dose of 10 mg/day or less in terms of prednisolone iii. steroids as premedication (eg ct premedication) 15. can be taken orally. 16. no ischemic changes were observed on the latest 12-lead ecg within 28 days before registration. however, if a 12-lead electrocardiogram shows ischemic changes, echocardiography, exercise electrocardiography, etc. should be performed, and if it is judged that new treatment for ischemic heart disease is not necessary, it is qualified. 17. the latest inspection value within 14 days before registration (possible on the same day two weeks before the registration date) satisfies all of the following. i. white blood cell count ≧4,000/mm3 ii. hemoglobin ≥ 11.0 g/dl (no blood transfusion within 14 days before the blood sampling date of the test used for registration) iii. platelet count ≧10×104 /mm3 iv. total bilirubin ≤ 2.0 mg/dl v. ast ≤ 75 u/l vi. alt ≤ 75 u/l vii. serum creatinine ≤ 1.2 mg/dl 18. written informed consent from the patient
