FIGURE 1 Columns represent percent of each histologic non-small cell lung cancer subtype within total IIIA/N2 stage population. Each column has two different parts, depending on skip metastases presence. Note that skip N2+ subgroup represents almost 50% of N2+ squamous cell lung cancer population. Adenoca, adenocarcinoma.

FIGURE 2 Five-year survival rates after surgery according to N status. The fourth and the fifth years of follow-up refer only to one third of the patients because the other two thirds survived to 3-year follow-up. Differences in survival rates for N0, N1, and N2 groups are statistically significant (p < 0.05).

FIGURE 3 Five years after surgery, the survival of the different pN2+ subgroups is shown. Although one-level skip pN2+ is a subgroup of the N2 group with a better prognosis, differences in survival rates for one-level skip N2+, multilevel skip N2+, and N2+ (N1+) groups are not statistically significant (p > 0.05).
