Fig 2 The disease-free survival curve for pulmonary adenocarcinoma measuring 3.0 cm or less with T1 N0 M0 or T2 N0 M0. The disease-free survival for patients with NE-2 tumors is significantly lower than that those for patients with NE-0 and NE-1 tumors (p < 0.0005). NE-0 was defined as tumor negative for all neuroendocrine markers, NE-1 as tumor having 1% to 9% positive cells with at least one neuroendocrine marker, and NE-2 as tumor having 10% or more positive cells with at least one neuroendocrine marker. (NE = neuroendocrine.) The Annals of Thoracic Surgery 2002 73, 1732-1735DOI: (10.1016/S0003-4975(02)03504-X)
