Table 2 CTC detection and expression of the genes in CD45-depleted peripheral blood at levels higher than those of healthy donors

Gene	Number of positive samples	% of positive samples
KRT19	20	13.6
TWIST1 ^a	4	2.7
SNAIL1	0	0.0
SLUG ^a	17	11.6
ZEB1	0	0.0
CTC_EP only	17	11.6
CTC_EMT only	17	11.6
CTC co-expressing both markers^b	3	2.0
Any CTC	37	25.2

^aIn one patient sample, there was overexpression of two EMT-inducing TF gene transcripts (SLUG and TWIST1)
^bIn one sample there was co-overexpression of KRT19 and SLUG, while in other two samples there was co-overexpression of KRT19 and TWIST1
