CTCs can be used to distinguish LC patients from the control (BLD patients + HD) when CTC cut-off is set to 2.

CTCs, circulating tumor cells; LC, lung cancer; HD, healthy donor; BLD, benign lung disease; n, number; TNM, tumor-node-metastasis.
Bold values mean statistically significant. Bold values are all less than 0.05.
