Prognostic value of circulating tumor cells combined with neutrophil-lymphocyte ratio in patients with hepatocellular carcinoma

Figure 2 Comparison of the area under the time-dependent receiver operating characteristic curve for overall survival prediction. A-C: Comparison of predictive efficacy of circulating tumor cell (CTC)-neutrophil-to-lymphocyte ratio (A), CTC programmed death-ligand 1 (+) (B), and alpha-fetoprotein (C) indicators at 6, 12, and 18 months in hepatocellular carcinoma patients. CTC: Circulating tumor cell; PD-L1: Programmed death-ligand 1; NLR: Neutrophil-to-lymphocyte ratio; AFP: Alpha-fetoprotein; AUC: Area under the curve.
