Risk factors for recurrence and metastasis of stage IIIC colorectal cancer: A two-center retrospective cohort study

Figure 1 Receiver operating characteristic curve plotted to discriminate metastatic lymph node ratio. AUC: Area under the curve.

Figure 2 Kaplan-Meier curves for 3-year disease-free survival of prognostic factors following radical surgery in stage IIIC colorectal cancer. A: Carcinoembryonic antigen (CEA) ≥ 5 µg/L vs CEA < 5 µg/L, P < 0.001; B: Metastatic lymph node ratio (MLR) ≥ 0.51 vs MLR < 0.51, P < 0.001; C: Positive root lymph node vs negative root lymph node, P < 0.001. CEA: Carcinoembryonic antigen; MLR: Metastatic lymph node ratio.
