Background: Nestin is a class 6 intermediate filament protein expressed in stem/progenitor cells during CNS development. Nestin expression has been detected in many kinds of tumors and was reported in a recent small-scale study in non-small cell lung cancer (NSCLC). We investigated the relationships between nestin expression and clinicopathologic parameters and determined its prognostic significance concerning survival in patients with resected NSCLC.Methods: Nestin expression in tumor cells was studied immunohistochemically in 171 consecutive patients with NSCLC, and associations with clinicopathologic parameters were evaluated. Kaplan-Meier survival analysis and Cox proportional hazards models were used to estimate the effect of nestin expression on survival.Results: Nestin expression was observed in tumor cell samples in 27 of the 171 patients with NSCLC (15.8%). Nestin had only cytoplasmic expression. Clinicopathologically, nestin expression was significantly associated with squamous cell carcinoma (P=.001), poorer differentiation (P=.007), lymph node metastasis (P=.008), intratumoral vascular invasion (P=.003), intratumoral lymphatic invasion (P=.008), pleural invasion (P=.039), and poorer prognosis (P
