GAL and colorectal carcinoma: Univariate analysis revealed that high GAL expression was associated with both poor 5-OS and poor 5-RFS in patients with stage II CRC [5-OS: hazard ratio (HR), 5.32; 95% confidence interval (CI), 1.93–14.74; P=0.002; 5-RFS: HR, 2.99; 95% CI, 1.26–6.65; P=0.02] (Table II), while there was no association between GAL expression and 5-OS and 5-RFS in patients with stage III CRC.
