As shown in Table 3, NDRG1 was a significant risk factor for OS in male patients (HR = 1.97, P = 0.003), patients aged above 60 (HR = 1.78, P = 0.014), patients at N0 stage (HR = 1.55, P = 0.048), patients at M0 stage (HR = 1.60, P = 0.034), patients with vascular invasion (HR = 2.19, P = 0.028), and patients with tumor (HR = 1.58, P = 0.048). Here, NDRG1 is linked to neoplasm.
