#3733 New insights on the clinical role of Ki-67 and spindle cell and oncocytic histological variants in lung carcinoid tumors

Introduction: WHO classification defines lung carcinoid tumors (LCTs) as well-differentiated neuroendocrine neoplasms classified in typical (TC) and atypical carcinoids (AC). Morphologic factors and protein expression able to predict recurrence after surgical curative resection are little known. Ki-67 and spindle cell and oncocytic histological variants may impact on differential diagnosis, but their clinical relevance is much debated.

#3151 Immunohistochemical evaluation of vimentin aberrant expression in lung carcinoid tumors

Introduction: The carcinoid tumors of lung represent a rare group of epithelial well-differentiated neuroendocrine neoplasms with common morphological characteristics and highly variable clinical course. Vimentin is a type III intermediate filament that is involved in cell migration and adhesion. Vimentin also drives epithelial to mesenchymal transition (EMT) and metastasis in solid tumors. However, no information exists for vimentin expression levels and the characterization of EMT phenotypes of lung carcinoid tumors.
