Abstract

Aims: Laryngeal squamous cell carcinoma (LSCC) prognosis is definitely related to lymph node metastasis. Epithelial-mesenchymal transition (EMT) allows neoplastic cells to gain the plasticity and motility required for tumour progression and metastasis. The aim of this study was to investigate the role of EMT in the prognosis of LSCC. Methods and results: Immunohistochemical analysis of E-cadherin, N-cadherin, Snail, Slug, ZEB1, and ZEB2 was performed in 37 consecutive LSCC cases. Low E-cadherin levels and high Slug levels correlated with both disease recurrence (P = 0.02 and P =0.01, respectively) and shorter disease-free survival (DFS) (P = 0.04 and P = 0.02, respectively). Relative expression levels of CDH1, SNAI2, miR-1 and the miR-200 family were also evaluated. CDH1, miR-200a and miR-200c down-regulation and SNAI2 overexpression were significantly associated with disease recurrence (P = 0.03, P = 0.02, P = 0.04, and P = 0.04, respectively). Conclusions: EMT increases tumour recurrence risk and shortens DFS in LSCC. E-cadherin and Slug immunohistochemical analysis could be useful for identifying patients requiring more aggressive treatment after surgery.
