Univariate analysis of the prognostic factors for 513 patients.
Figure 1.
Stage migration in 88 patients and survival curves of patients according to the pN category and npN category.
A: The number of patients who had stage migration in different subcategories. B: Survival curves showed different prognostic outcomes among patients with pN1a, pN1b, pN2a, and pN2b (P<0.001). C: Survival curves showed different prognostic outcomes among patients with npN1a, npN1b, npN2a, and npN2b (P<0.001).

Multivariate Analysis (Cox Proportional Hazard Model) of Prognostic Factors for 513 Patients with the npNa category.
Figure 2.
Survival curves of patients with or without TDs in the same npN categories.
A: Survival curves showed similar prognostic outcomes between patients with or without TDs in npN1b (p = 0.297). B: Survival curves showed similar prognostic outcomes between patients with or without TDs in npN2a (p = 0.742). C: Survival curves showed similar prognostic outcomes between patients with or without TDs in npN2b (p = 0.402).
