Comparison of Serum MicroRNA21 and Tumor Markers in Diagnosis of Early Non-Small Cell Lung Cancer

Table 1

Serum miR21, CEA, NSE, and CYFRA21-1 levels of study participants.

Group		CEA; (ng/mL)	NSE; (ng/mL)	CYFRA21-1; (ng/mL)	miR21; (arbitrary units)
Case	50
Control	60
		11.257	6.914	7.073	8.014
		<0.01	<0.01	<0.01	<0.01

miR21 expression was normalized against miR16 expression and is described in relative units.
