Correlation between CTC-enriched blood fractions gene expression status and clinicopathological parameters.

Number of cases classified as positive (Pos.) or negative (Neg.) for a particular marker in each group are shown. Statistically significant P values are given in bold.*CTC-enriched blood fraction phenotype – only MBG1+ and/or HER2+ fractions were considered** CK19−/VIM+ - mesenchymal phenotype; CK19+/VIM− - epithelial phenotype.
