Table 2. Distribution of CA125 and HE4 expression and Chr8 aneuploidy in CTCs and CTECs detected by SE-iFISH in 20 ovarian cancer patients.

Variables	Detection rate of patients [% (n/N)]				Cells proportion [% (n/N)]
	CA125+	HE4+	Chr8 aneuploidy		CA125+	HE4+	Chr8 aneuploidy
CA125, carbohydrate antigen 125; HE4, human epididymis protein 4; Chr8, chromosome 8; CTC, circulating tumor cell; CTEC, circulating tumorigenic endothelial cell; SE-iFISH, subtraction enrichment and immunostaining and fluorescence in situ hybridization.
CTC	20 (4/20)	25 (5/20)	95 (19/20)		4.8 (10/210)	4.3 (9/210)	99.5 (209/210)
CTEC	30 (6/20)	25 (5/20)	80 (16/20)		14.4 (26/180)	6.1 (11/180)	100 (180/180)
