Comparison between adenocarcinoma (AD) and squamous cell carcinoma (SQ) in patients with non-small cell lung cancer (NSCLC)

Marker	NSCLC AD Median (IQR)	NSCLC SQ Median (IQR)	P-value
TGF-β1 (ng/dl)	50 (38-65)	51 (42-61)	0.823
SMAD2 (ng/dl)	2.2 (1.8-2.5)	2.3 (1.3-2.6)	0.638
WNT3a (ng/dl)	2.5 (1.3-5.2)	2.8 (1.9-4.3)	0.658
CTNN-β1 (ng/dl)	3.6 (2.4-4.4)	3.5 (2.5-5.3)	0.879

TGF-β1 – transforming growth factor β1, SMAD2 – mothers against decapentaplegic homolog 2, Wnt3a – wingless-related integration site, CTNN-β1 – β-catenin, AD – adenocarcinoma, SQ – squamous cell carcinoma
