ROC curves for survival prediction. (a) Kaplan–Meier curves for progression-free survival (b) and overall survival (c) probability according to the CEA + CYFRA211 + NLR + RDW-SD + LDH level. CEA: carcinoembryonic antigen; CYFRA211: serum cytokeratin-19 fragment; NLR: neutrophil-to-lymphocyte ratio; RDW-SD: red blood cell distribution width-standard deviation; LDH: lactate dehydrogenase; AUC: area under the curve.
