1 Prognostic significance of neuroendocrine differentiation in adenocarcinoma of the lung 
Kenzo Hiroshima, MD, Akira Iyoda, MD, Kiyoshi Shibuya, MD, Tetsuya Toyozaki, MD, Yukiko Haga, MD, Takehiko Fujisawa, MD, Hidemi Ohwada, MD  The Annals of Thoracic Surgery  Volume 73, Issue 6, Pages (June 2002) DOI: /S (02)03504-X

2 Fig 1 Immunohistochemical staining of pulmonary adenocarcinoma of the lung with polyclonal antichromogranin A antibody. The tumor cells stain positive with antichromogranin A antibody (original magnification ×50). The Annals of Thoracic Surgery  , DOI: ( /S (02)03504-X)

3 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 < ). 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  , DOI: ( /S (02)03504-X)
