ALB and neoplasm: The elevated LDH (HR=2.204, 95%CI=1.000-4.858, P=0.050), reduced ALB (HR=0.459, 95%CI=0.236-0.892, P=0.022), elevated LDH combined with elevated SLA (HR=3.187, 95%CI=1.019-9.970, P=0.046), and the primary site of tumor (HR=0.359, 95%CI=0.174-0.740, P=0.006) were independent prognostic factors for OS of patients with mCRC.
