Correlation of clinicopathological parameters with EGFR and Her-2 neu status in oral cancer patients in a tertiary care centre
Journal Title: International Journal of Biomedical Research - Year 2015, Vol 6, Issue 11
Abstract
Background: Oral squamous cell carcinoma (SCC) is one of the most frequent cancers in the world. The overall postoperative survival has not improved much despite advanced surgical techniques and anticancer drugs. A better understanding of molecular mechanisms and identification of potential oncogenes in oral carcinomas may provide new therapeutic decisions such as target therapy in the treatment of these patients. Aims & objectives: The present study aimed at analyzing the clinicopathological profile of patients with oral SCC and also, to determine the levels of expression of EGFR and Her-2 neu in these lesions and carry out their correlation with the clinicopathological parameters. Material and Methods: The expression of EGFR & Her-2 neu was studied in paraffin embedded tissue sections of oral SCC after taking a detailed history and examination. Results and Conclusion: EGFR was positively expressed in 84.4% (38/45) of squamous cell carcinomas and 79% (19/24) of dysplasias. While Her-2 neu was positively expressed in 62.2% (28/45) of carcinomas and 66.7% (16/24) of dysplasias. The correlation between tumor differentiation and immunomarker expression came out to be significant for EGFR but not Her-2 neu. Thus, a high level of EGFR is strongly associated with tumor aggressiveness. Molecular targeting of EGFR can therefore, is used for adjuvant treatment in malignancy.
