EBP samples and measurements of PFR will be collected from patients with primary non-small cell lung cancer (NSCLC) at Skåne University Hospital (SUS) Lund. Measurements will be done at 2 time points, before and after surgical resection for NSCLC.
EBP samples will be collected at one time point from a matched (by age and smoking history) control cohort.
Blood samples will be collected from both cohorts, at the same time points as the EBP/PFR measurements.
Tumor tissue and healthy adjacent lung tissue will be collected from lung cancer patients with tumors greater than 3 cm in diameter on preoperative computed tomography.
The purpose of this clinical trial is to identify non-invasive means of diagnosing NSCLC at earlier stages. The PExA method is not associated with any risks and has potential minimize hospitalization associated with more invasive methods that are in clinical practice today, such as bronchoscopy and biopsies.
