Aims: To investigate the relationship between E-cadherin, beta-catenin, N-cadherin, ZEB1, and αSMA as epithelial-mesenchymal transformation markers with tumor stage, lymph node metastasis (LNM), and overall survival (OS) in laryngeal squamous cell carcinomas (LSCC). Material and Method: A total of 100 cases diagnosed with LSCC were included in the study. Data about the lymphovascular invasion (LVI), perineural invasion (PNI), necrosis, and LNM were recorded by evaluating hematoxylin-eosin–stained slides. Markers of E-cadherin, beta-catenin, N-cadherin, ZEB1, and αSMA were applied to the sections prepared from paraffin blocks of tumor samples. Results: Ninety-five male and five female patients were included in the study, and 38 of them exited. A significant relationship was observed between OS with advanced tumor stage, presence of LNM and PNI. A significant relationship was found between increased tumor Zeb1 expression and advanced tumor stage. In univariate and multivariate analyses, a significant negative relationship with OS, and increased Zeb1 expression in tumor and tumor stroma was seen. Any relationship was not observed between E-cadherin, beta-catenin, N-cadherin, and αSMA and OS. Conclusion: Among the EMT markers, we evaluated in our study, it was seen that Zeb1, which is an EMT transcription factor, is associated with tumor stage, LNM, and OS. Remarkably, Zeb1 expression observed in tumor stroma was also significant for OS. Any similar data reported for LSCCs have not been encountered in the literature, and it was thought that it would be appropriate to support our findings with further studies to be performed on this subject.
