Inclusion Criteria

Primary enrollment eligibility criteria
(1) All of the following are met by contrast-enhanced CT, thin slice CT of the chest, FDG-PET/CT, and contrast-enhanced CT of the brain or MRI.
(i) Suspected non-small cell lung cancer of clinical stage T1miabN0M0.
(ii) Tumor center is located in the peripheral lung field (mantle one-third).
(iii) Whole tumor size is 2 cm or smaller.
(iv) Solid predominant tumor (C/T ratio > 0.5).
(v) The primary site of the tumor is not in the middle lobe.
(2) No secondary tumor.
(3) No confirmed diagnosis of neuroendocrine tumor if histopathology or cytology was performed prior to primary enrollment.
(4) 80 years or older.
(5) Performance status is 0 or 1 according to ECOG criteria.
(6) No history of any drug therapy other than endocrine therapy (cytotoxic anticancer drugs, molecular targeted drugs, or immune checkpoint inhibitors) within 2 years, including treatment for other types of cancer.
(7) If there is a history of radiotherapy including other types of cancer, the thoracic region (lung, hilar region, mediastinum) is not included in the irradiation field.
(8) The patient tolerate lobectomy. All of the following are met.
(i) Predicted postoperative volume in 1 second (ppoFEV1.0) is >= 800 mL.
(ii) Preoperative resting SpO2 >= 92%. If the resting SpO2 is < 92%, PaO2 is >= 65 mmHg.
(9) No interstitial pneumonia or pulmonary fibrosis as diagnosed by chest CT.
(10) Either (i) or (ii) of modified MRC is met.
(i) Modified MRC is Grade 0 or 1 (echocardiography is not required).
(ii) Modified MRC is Grade 2 and left ventricular ejection fraction exceeds 40% on echocardiography.
(11) Patient meets either (i), (ii), or (iii) regarding the latest resting 12-lead ECG.
(i) No ischemic changes, atrial fibrillation, atrial flutter, two or more consecutive premature ventricular contraction, newly emerged complete left bundle branch block, or pacemaker rhythm.
(ii) If ischemic changes are present, echocardiography and exercise stress echocardiography are performed, and it is determined that treatment for ischemic heart disease is not warranted.
(iii) In the presence of atrial fibrillation, atrial flutter, two or more consecutive premature ventricular contraction, newly emerging complete left bundle branch block, or pacemaker tuning, echocardiography is performed and left ventricular ejection fraction exceeds 40%.
(12) The most recent laboratory data within 28 days prior to primary enrollment (the same day of the week 4 weeks prior to the primary enrollment date is acceptable) meet all of the following.
(i) White blood cell count >= 3,000/mm3
(ii) Hemoglobin >= 8.0 g/dL (no blood transfusion within 14 days prior to the blood draw for the test used for registration)
(iii) Platelet count >= 100,000/mm3
(iv) Total bilirubin <= 2.5 mg/dL
(v) AST <=100 U/L
(vi) ALT<=100 U/L
(vii) Serum creatinine <= 2.0 mg/dL
(13) Consultation with radiology/radiotherapy department and full explanation of the study, including stereotactic body radiation therapy (SBRT) as a treatment option, prior to primary enrollment (any form of consultation is acceptable, but the details must be documented in the medical record).
(14) Written consent to participate in the study has been obtained from the patient.

Secondary (intraoperative) enrollment eligibility criteria
(1) Primary enrollment in the study and the secondary enrollment date is within 28 days of the primary enrollment date (the same day of the week 4 weeks later is acceptable).
(2) Preoperative

Exclusion Criteria

(1) Active multiple cancers (synchronous double cancers / multiple cancers and metachronous double cancers / multiple cancers with disease-free period of 3 years or less.
(2) Infectious disease requiring systemic treatment.
(3) Body temperature >= 38.0C at the time of enrollment.
(4) Patients with psychiatric disorders or psychiatric symptoms that interfere with daily life and make participation in the study difficult.
(5) Receiving continuous systemic administration (oral or intravenous) of steroids or other immunosuppressive drugs.
(6) Uncontrolled diabetes mellitus (HbA1c > 8%).
(7) Uncontrolled hypertension.
(8) Unstable angina (angina with onset or worsening within the last 3 weeks) or a history of myocardial infarction within 6 months.
(9) Poorly controlled valvular disease, dilated cardiomyopathy, or hypertrophic cardiomyopathy.
