We investigated whether biomarker analysis in endobronchial epithelial lining fluid (ELF) collected by bronchoscopic microsampling may be useful for a definitive preoperative diagnosis. Therefore we compared ELF samples close to nodule and from the contralateral site from patients with malignant or benign diagnosis. Overall design: ELF samples have been derived from early stage NSCLC patients and controls. LIMMA analysis was performed to identify differentially expressed genes associated to a malignant diagnosis. keywords: disease subtype analysis
