In patients with recurrent CRC, those of Black race (P = 0.0030), age over 65 years (P < 0.0001), with a tumor size of >5 and ≤10 cm (P = 0.0035), T2 stage (P = 0.0005), and positive/elevated CEA levels (P < 0.0001) exhibited a significantly poorer survival (Figure 3). This evidence concerns the gene CEACAM5 and neoplasm.
