Long-term survival according to the pN status and the type of pN2 involvement. (A) Long-term survival of pN0, pN1, and pN2 patients. pN0 (n = 2,317) median 80 months, 5-year 58.6%, 10-year 37.3%. pN1 (n = 722) median 48 months, 5-year 45.1%, 10-year 26.8%. pN2 (n = 871) median 23 months, 5-year 25.4%, 10-year 17% (p < 0.001). (B) Long-term survival of pN2-1S and pN2-2S. pN2-1S (n = 575) median 26 months, 5-year 29.8%, 10-year 20.6%. pN2-2S (n = 296) median 16 months, 5-year 16.8%, 10-year 9.7% (p < 0.001). (C) Long-term survival of pN0N2-1S, pN0N2-2S, pN1N2-1S, pN1N2-2S patients (p < 0.001).
