Creatinine ≤1.25 times the upper limit of normal value and creatinine clearance ≥60ml/min;
• The center of the lesion is located in the other lobes except the middle lobe, and in the middle and outer third of the lung;
• The maximum diameter of the tumor was not more than 2cm on TLC(Thin layer CT) scan and the clinical stage was cT1a-1bN0M0(according to AJCC staging criteria, eighth edition);
• Consolidation tumor rate \<1；
• ECOG PSscore 0-1;
• All relevant examinations should be completed within 28 days before surgery;
• Patients who understand the study and have signed informed consent.
