Various biomarkers have been proposed to predict CRC outcomes, such as MMP7 [8], miR21, miR106a, miR135, miR17-92 [9,10] CK19, CK20, or Carcinoembryonic antigen (CEA) [11,12] miR29a and miR92a [13], Cancer antigen 19–9 (CA 19–9) [14–18]. The gene discussed is CEACAM5; the disease is colorectal carcinoma.
