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

Figure 1 Survival rate comparison. A and B: Kaplan-Meier overall survival (OS) curves (A) and progression-free survival (PFS) curves (B) in different subgroups of hepatocellular carcinoma (HCC) patients with circulating tumor cell programmed death-ligand 1 (+); C and D:Kaplan-Meier OS curves (A) and PFS curves (B) in different subgroups of HCC patients with neutrophil-to-lymphocyte ratio; E and F: OS curves (A) as well as PFS curves (B) for different subgroups of HCC patients with circulating tumor cell-neutrophil-to-lymphocyte ratio. HR: Hazard ratio; CTC: Circulating tumor cell; PD-L1: Programmed death-ligand 1; NLR: Neutrophil-to-lymphocyte ratio.
