Eligibility
Inclusion criteria
Inclusion criteria: 1.(1) Clinically diagnosed with stage I non-small cell lung cancer (NSCLC) in accordance with the 9th edition TNM staging system of the International Association for the Study of Lung Cancer (IASLC). (2) Preoperative thin-slice computed tomography (CT) confirmed peripheral lesions predominantly composed of ground-glass nodules, with a maximum diameter = 18 years, regardless of gender. 4. Follow-up duration >= 6 months, or until the occurrence of clinical outcome events such as death and disease recurrence. 5. Complete information on exposure factors and outcome indicators is available in the clinical data of patients. 6. Additional reasonable inclusion criteria may be supplemented on the premise that all the above criteria are satisfied.
Exclusion criteria
Exclusion criteria: 1.(1) Pathological diagnosis other than adenocarcinoma or squamous cell carcinoma; (2) Carcinoid tumors; (3) Evidence of lymph node metastasis or distant metastasis; (4) Receipt of neoadjuvant therapy; (5) Severe interstitial lung disease precluding the scheduled surgical procedure. 2. Incomplete medical records with missing critical information including exposure factors, outcome indicators and follow-up data; inability to contact patients, rendering data extraction and analysis unfeasible. 3. Loss to follow-up during the follow-up period. Definition of loss to follow-up: inability to contact patients, refusal of subsequent follow-up, or follow-up duration less than 6 months without any outcome events occurring. 4. Explicit refusal of study participation by patients or their families (with documented denial of research authorization in medical records). 5. Other conditions that may compromise the authenticity of study results, such as complicated mental disorders or cognitive impairment, leading to failure in follow-up compliance and data collection.
