CTC count comparisons across study subgroups. (A) Correlations of CTC counts with CEA at C1 in patients who had disease relapse and were treated with adjuvant chemotherapy (biomarkers data available for 7/7 cases at C1; Spearman's ρ = 0.95; p = 0.001). (B) Median CTC counts at C1 in smokers/former smokers versus in non-smokers (p = 0.05; Mann-Whitney U). (C) Median CTC counts at C2 in smokers/former smokers versus in non-smokers (p = 0.04; Mann-Whitney U). *Smokers/former smokers were grouped in the x-axis “yes” classification.
