LcProt: Proteomics Longitudinal Cohort Study on Lung Cancer

Summary

This study will utilize tissue and peripheral blood samples for proteomics analysis and establish a longitudinal proteomics cohort at multiple critical treatment time points to explore the research value of proteomics in the diagnosis and treatment of lung cancer. The study includes key time points such as screening, postoperative efficacy prediction, and efficacy prediction after medication.

6. The interval between preoperative pulmonary function and single/dual phase CT scans does not exceed one month.

Exclusion Criteria:

1. Poor preoperative pulmonary function cooperation or missing reports;
2. Preoperative chest single/dual phase CT scans exhibit significant artefacts or image omission;
3. The interval between preoperative pulmonary function and single/dual phase CT scans exceeds one month;
4. Complication with severe respiratory disorders (such as lung transplantation, pneumothorax, giant bullae, etc.);
