Multivariate Cox proportional hazards regression analysis showed that BMI (>25.55), AFP (>73.2), tumor number (>3), differentiation (1–2), and SIRI (>1.25) were independent related factors for OS [hazard ratio (HR) = 0.924, P = 0.029; HR = 2.376, P = 0.002; HR = 2.193, P = 0.002; HR = 3.006, P = 0.024; and HR = 2.258, P = 0.024, respectively] (Table 2). Here, AFP is linked to neoplasm.
