Design
Arms and outcomes
Arms (1)
- label
- preoperative enhanced chest CT
- description
- The cohort contains patients with preoperative therapies and patients without preoperative therapies. Each patient receives regular preoperative enhanced chest CT; for patients with preoperative therapies, they usually undergo twice enhanced chest CT examination at before and after preoperative therapies, the CT images after preoperative therapies will be used for analysis
- interventionNames
- Procedure: preoperative enhanced chest CT examination
Primary outcomes (1)
- measure
- pathological local lymph node status
- timeFrame
- Pathologic evaluation will be performed for each patient within 1 week after surgery
- description
- pathological lymph node status is defined as lymph node metastasis exist or not
