As shown in Figure 4, the concentrations of HSP70, CK19, and CA125 were significantly higher in CRC patients compared with healthy controls (HSP70 p < 0.0001; CK19 p < 0.0001; CA125 p = 0.0124), whereas TAG72 (p = 0.1559) levels did not differ between groups. This evidence concerns the gene KRT19 and colorectal carcinoma.
