Clinically definite suspected primary NSCLC after complete preoperative work-up and MDT discussion, with estimated malignancy probability \\>=95%. Preoperative pathologic confirmation is not mandatory, but preoperative or intraoperative pathology should be obtained when technically safe and feasible.\n6. Complete staging with thin-slice contrast-enhanced chest CT, whole-body PET-CT, brain contrast-enhanced MRI or CT, and serum tumor markers as appropriate; clinical stage IA (cT1a-bN0M0) without regional nodal or distant metastasis.\n7.

Lesion located in the inner two-thirds but adjacent to the lung apex or base and judged suitable for wedge resection.\n3. Two or more lesions requiring anatomic resection. One secondary lesion requiring only non-anatomic wedge resection is allowed; two main lesions in the same segment are excluded.\n4. Prior ipsilateral lung surgery or another malignancy within 5 years.\n5.
