Fig 1 (A) LCC with nucleoli evident, lower nuclear-to-cytoplasmic ratio, and absence of neuroendocrine features. (Hematoxylin & eosin; ×200 before reduction.) (B) LCNEC (hematoxylin & eosin; ×100 before reduction) and (C) LCCNM (hematoxylin & eosin; ×200 before reduction) show a neuroendocrine morphology with organoid nesting, palisading, and rosettes. Numerous mitoses are seen. Cytologic features include large cell size, fine chromatin, and nucleoli evident. (D) The tumor cells stained with anti-chromogranin A antibody; only the LCNEC tumors stained for chromogranin. (×200 before reduction.) (LCC = large cell carcinoma; LCNEC = large cell neuroendocrine carcinoma; LCCNM = large cell carcinoma with neuroendocrine morphology.) The Annals of Thoracic Surgery , DOI: ( /j.athoracsur )

Fig 2 (A) Kaplan–Meier curve demonstrating the impact of surgery on survival. Surgery type: - ♢ - = pneumonectomy; — ■ — = bilobectomy; –▵– = lobectomy. (B) Effect of histologic subtype on survival. Group: — ■ — = LCNM; - ♢ - = LCNEC; –▵– = LCC. (LCC = large cell carcinoma; LCNM = large cell carcinoma with neuroendocrine morphology; LCNEC = large cell neuroendocrine carcinoma.) (C) Kaplan–Meier curve demonstrating the effect of MVD on survival. Upper curve < 30% of MVD in tumor; lower curve < 30% of MVD in tumor. Cut points in MVD: = 3.01–12.8%; —— = 0.0–3.0%. (MVD = microvessel density.) (D) Kaplan–Meier curve demonstrating the effect of p21 on survival. Upper curve < 35% of tumor staining; lower curve < 37% of tumor staining. Cut points in p21: = 3.7–46.6%; —— = 0.0–3.7%. The Annals of Thoracic Surgery , DOI: ( /j.athoracsur )
