Background: Oral squamous cell carcinoma (OSCC) is among the frequently reported malignancies in Pakistan having unfavorable prognosis. Extracellular Matrix Metalloproteinase Inducer (EMMPRIN) is a transmembrane glycoprotein that is implicated in tumorigenesis and is recognized as a potential therapeutic target in multiple carcinomas.

Objective: To determine the immuohistochemical expression of EMMPRIN (CD147) in biopsies from OSCC patients in the Pakistani population.

Methods: This descriptive study was conducted in Lahore, Pakistan, comprising 100 OSCC cases presenting, from January 2010 to September 2015. Detailed clinical parameters were recorded. Histological diagnosis & grade was assessed followed by scoring of CD147 immunoexpression into low (score 0-5) and high (score 6-7). The data were analysed using SPSS 21.0. Pearson Chi square and Fisher Exact test were applied. A P value ≤0.05 was considered as statistically significant.

Results: Histologically, conventional OSCC was the most prevalent subtype (92%) followed by oral papillary (6%) and verrucous (2%) carcinomas. Well differentiated carcinomas made most of the tumour burden (64%). 60% carcinomas expressed high score while 40% showed low expression scores. EMMPRIN expression was significantly associated with the degree of differentiation of the tumour (P=0.001).

Conclusions: The findings of the current study highlight the significance of EMMPRIN (CD147) expression in relation to cancer progression thus marking its potential for being an attractive target for immunotherapeutic approaches.
