Prognosis of patients with gastric cancer and solitary lymph node metastasis

Figure 1 Cumulative survival of patients with gastric cancer + solitary lymph node metastasis according to age category.

Figure 2 Correlation between age (≤ 50 years-old) and mean survival days after surgery in patients with gastric cancer + solitary lymph node metastasis (r = 0. 367; P < 0.001).

Figure 3 Survival curves for patients with gastric cancer + solitary lymph node metastasis according to metastatic lymph node ratio category. Survival is shown to be inversely associated with the ratio of positive nodes to lymph nodes harvested during surgery.

Figure 4 Cumulative survival of patients with gastric cancer + solitary lymph node metastasis and different metastatic lymph node ratio according to age category. A: P < 0.05 for comparisons among all three groups; B: Younger patients have significantly worse survival than the two older patient groups (P < 0.01); C: There are no significant differences among the three groups. Cumulative survival of patients with metastatic lymph node ratio (MLR) ≥ 0.06 (A), 0.04-0.06 (B), and < 0.04 (C) by age.
