Multivariable survival analyses identified carcinoembryonic antigen levels (hazard ratio [HR]\xa0=\xa03.056; 95% confidence interval [CI]\xa0=\xa01.354-6.897; P\xa0=\xa00.007), treatment strategy (HR\xa0=\xa00.212; 95% CI\xa0=\xa00.056-0.808; P\xa0=\xa00.023), and CD133+ CD44+ CD54+ cellular subpopulation of CTCs (HR\xa0=\xa06.459; 95% CI\xa0=\xa01.461-28.558; P\xa0=\xa00.014) as independent prognostic factors for CRC patients with liver metastasis.
