Abstract

Lung cancer as the major cause of cancer mortality worldwide includes several histologic subtypes evolving from numerous genetic and epigenetic changes emerging in alveolar, bronchiolar and bronchial epithelium. Th e majority of cases are diagnosed in advanced stage (i.e. stages IIIB and IV), often with scanty amount of tissue in transbronchial biopsies or cytology specimens. Th e aim of the present study was to investigate the expression of the scaff olding protein neural precursor cell expressed, developmentally downregulated 9 (NEDD9) in small biopsies of lung adenocarcinoma. The expression of NEDD9 was analyzed immunohistochemically in 71 formalin-fi xed and paraffin-embedded transbronchial biopsy specimens of primary lung adenocarcinoma. Nuclear and cytoplasmic NEDD9 expression was detected indicating activation of the epithelial-mesenchymal transition process. Direct relationship between the expression of NEDD9 and survival was not
demonstrated.
