EGFR is an important transmembrane receptor member of the family of tyrosine kinases, that translates signals from both outside and inside the cell and plays a key role in numerous proceses that affect tumour development, growth, progresion, differentiation, inhibition of apoptosis and metastasis. Immunohistochemistry studies have shown that 40-80% of head and neck squamous cell carcinomas express EGFR and it has been suggested as a potential independent prognostic parameter. The objective of this study is to evaluate by immunohistochemistry the expresi6n of EGFR in a series of Head and Neck Squamous Cell Carcinoma and correlate it to clinico-pathological features and prognostic significance. We investigated expression of EGFR in 44 samples. There was a high expression in 41% of the cases. Even if we have not found that the expression of EGFR correlated with the prognosis of these patients the presence of EGFR is very important because there are chemical agents or drugs that can inhibit its activity.
