Overall survival (OS). A, Entire cohort: the 5-year OS was 39% (95% confidence interval [CI], 28%-56%). B, Postinduction positron emission tomography (PET) N2 status: The 5-year OS for N2-negative was 43% (95% CI, 22%-83%) versus 39% (95% CI, 23%-64%) for N2-avid disease (P = .251). C, Pathologic N2 status: The 5-year OS for N2-negative was 40% (95% CI, 25%-64%) versus 38% (95% CI, 21%-67%) for N2-persistent disease (P = .936). D, Pathologic staging: The 5-year OS for < ypIIIA was 41% (95% CI, 25%-66%) versus 37% (95% CI, 21%-66%) for ≥ ypIIIA (P = .791).

Disease-free survival (DFS). A, Entire cohort: The 5-year DFS was 23% (95% confidence interval [CI], 14%-37%). B, Postinduction positron emission tomography (PET) N2 status: The 5-year DFS for N2-negative was 24% (95% CI, 11%-51%) versus 24% (95% CI, 11%-54%) for N2-avid disease (P = .867). C, Pathologic N2 status: The 5-year DFS for N2-negative was 34% (95% CI, 21%-56%) versus 9% (95% CI, 2%-45%) for N2-persistent disease (P = .079). D, Pathologic staging: The 5-year DFS for < ypIIIA was 36% (95% CI, 22%-58%) versus 9% (95% CI, 2%-44%) for ≥ ypIIIA (P = .054).

Cumulative incidence of recurrence (CIR). A, Entire cohort: The 5-year CIR was 70% (95% confidence interval [CI], 60%-81%). B, Postinduction positron emission tomography (PET) N2 status: The 5-year CIR for N2-negative was 76% (95% CI, 58%-99%) versus 58% (95% CI, 41%-80%) for N2-avid disease (Gray's test, P = .571). C, Pathologic N2 status: The 5-year CIR for N2-negative was 59% (95% CI, 44%-79%) versus 80% (95% CI, 66%-96%) for N2-persistent disease (Gray's test, P = .077). D, Pathologic staging: The 5-year CIR for < ypIIIA was 57% (95% CI, 41%-78%) versus 80% (95% CI, 67%-96%) for ≥ ypIIIA (Gray's test, P = .049).
