Abstract

Introduction:HER2/neu, a member of the epidermal growth factor receptor family, has been shown to be over-expressed in some tumors. The purpose of this study was to determine the salivary levels and TISSUE EXPRESSION of HER2/NEU in patients with head and neck squamous cell CARCINOMA (HNSCC) and their correlation with clinicopathologic parameters.Materials and Methods:Enzyme-linked immunosorbent assays (ELISA) were used to evaluate the salivary levels of HER2/NEU and immunohistochemistry was used to measure TISSUE EXPRESSION of HER2/NEU in 28 patients with HNSCC and 25 healthy control subjects.Results:The salivary levels of HER2/NEU in patients with HNSCC were not significantly higher compared to healthy control subjects. There was no apparent correlation between salivary HER2/NEU levels and clinicopathological features such as age, sex, tumor grade, tumor size and nodal status. All HNSCC specimens were positive (membranous or/and cytoplasmic) for HER2/NEU, except one sample. Only one HNSCC specimen showed staining purely in the tumor-cell cytoplasm. All control specimens were also positive for both membranous and cytoplasmic HER2/NEU but there was a significant difference between the level of cytoplasmic staining in the HNSCC specimens and in the control specimens (P<0.05).Conclusion:In our study, no overexpression of HER2/NEU was observed. Thus, identification of HER2/NEU levels plays no role in differentiating between normal and squamous cell CARCINOMA tissues or detecting the carcinogenesis process. Our findings suggest that the use of HER2/NEU as a salivary marker of HNSCC is not recommended, because no significant preoperative elevation and no association with clinicopathological features were found.
