Parameter	Number of patients with >3		value
Smoking			0.19	——	1.69
Yes	120	28

Tumor size			0.29	——	1.14
≤3 cm	92	18
>3 cm	162	44
Differentiation			0.99	——	0.001
Poor	90	22
Well and moderate	164	40
Lymph node involvement			0.01	0.15	7
Yes	87	21
No	138	70
TNM stage			0.57	——	2.00
I	48	10
II	86	24

IV	51	11

indicates that the correlation was statistically significant. Only lymph node involvement was correlated with positive CTC detection.
