Abstract
Background: The molecular makeup of a head and neck squamous cell carcinoma (HNSCC) could vary as per the geography and corresponding variability in prevalent etiopathological factors. The objective of this study was to analyze the expression pattern of E-cadherin (E-cad), a transmembrane glycoprotein with tumour suppressor function, in a cohort of HNSCC treated at a tertiary care medical centre in the southern part of India. Material and methods: After obtaining the institutional ethics committee’s permission, the expression of E-cad in HNSCC was assessed by using immunohistochemistry on retrospectively collected tumour specimens, obtained by a surgical cohort of cases operated between September 2018 and July 2019. The E-cad expression was then correlated with various clinical and pathological characteristics of HNSCC, retrieved via the medical records of corresponding patients. Results: A total of 60 patients of HNSCC were included, most of whom had lesion in the oral cavity, in an advanced stage. The majority had a strong or moderate expression of E-cad on the surface. On analyzing further, oral cavity tumours had significantly less expression of E-cad compared to laryngeal and hypopharyngeal tumours taken together, and primary tumours had less E-cad expression than recurrent cases. Multivariate analysis with proportional odds regression showed the significant associations of low expression of E-cad expression with the moderate/poor differentiation of tumours and with the extranodal extension. Conclusions: Among the HNSCC, the loss of E-cad expression was mostly associated with primary tumours of the oral cavity, moderate/poorly differentiated tumours, and in those HNSCCs that had an extranodal extension.
