Detection of ALK Gene Rearrangement in Cell-free RNA from Lung Cancer Malignant Pleural Effusion

Table 2

Comparison of ALK gene rearrangement results in supernatant, sera, and cell blocks.

Cell blocks	Supernatant		Sera
	+	−	+	−
+	12	0	0	12
−	0	11	0	11
value (McNemar’s test)	=1.000		≤0.001
Kappa value	=1.000		=0.000

+, ALK positive rearrangement; −, ALK negative rearrangement.
