AFP and neoplasm: In the COR group, univariate and multivariate Cox analysis results showed AFP (HR = 1.416, 95% CI 1.195-1.679, p < 0.001), tumor size (6.2-9.3 cm: HR = 1.258, 95% CI 1.093-1.448, p = 0.001; > 9.3 cm HR = 1.602, 95% CI 1.405-1.827, p < 0.001), N stage (HR = 1.240, 95% CI 1.069-1.440, p = 0.005), M stage (HR = 1.786, 95% CI 1.550-2.058, p < 0.001) were independent risk factor of OS.
