Fig 1 Histologic evidence of lymph node treatment effect. Representative hematoxylin and eosin–stained lymph nodes (magnification ×40) with histologic evidence of prior cancer involvement, including (A) calcification and necrosis, (B) central fibrosis, or (C) acellular mucin.

Fig 2 Survival curve by nodal status: no evidence of nodal disease at any time (negative, solid line), treatment-response nodes (TRN) with evidence of prior nodal involvement but without viable cancer cells detected (dashed line) or with evidence of active nodal malignancy (positive, dashed-dot line).

Fig 3 Survival curves (A) by stage using the traditional American Joint Committee on Cancer staging criteria, (B) by stage (0-1, solid line; 2, dashed line; 3, dash-dot line) counting treatment-response nodes (TRN) as involved nodes, (C) in patients with no or limited nodal involvement (N0 or N1), comparing patients with (dashed line) and without (solid line) TRN-positive nodes, and (D) in patients with limited stage disease (0-2B) comparing patients with (dashed line) and without (solid line) TRNs.
