Abstract

The aim of this study was to evaluate periostin expression measured immunohistochemically in patients with non-small cell lung cancer (NSCLC) and to determine its association with clinical features, prognosis, angiogenesis, and lymphangiogenesis. We investigated periostin expression in a series of 88 patients with NSCLC. We also determined whether expression of periostin correlated with microvessel density and lymphatic microvessel density. Periostin was expressed in 42% of 88 patients. Its expression was significantly correlated with tumor size, lymph node metastasis, disease stage, and lymphatic invasion (p=0.0128, 0.0015, 0.0310 and 0.0273, respectively). There also was a significant relation between periostin expression and microvessel density and lymphatic microvessel density (all p<0.0001). Five-year survival rates were better in patients with negative periostin expression than in those with positive periostin expression (p=0.0044). Periostin expression was not significant in a multivariate additive model. Our findings show that periostin correlates with increased tumor progression and a worse prognosis in NSCLC, as well as with angiogenesis and lymphangiogenesis.
