In the multivariate analysis, treatment allocation (hazard ratio [HR] = 1.810, 95 % confidence interval [CI] = 1.215–2.697, P = 0.004), albumin level (HR = 1.819, 95 % CI = 1.233–2.685, P = 0.003), tumor size (HR = 1.732, 95 % CI = 1.160–2.587, P = 0.007), and tumor number (HR = 1.401, 95 % CI = 1.143–1.718, P = 0.001) were independent prognostic factors for OS (Table 2). Here, ALB is linked to neoplasm.
