Abstract

Objective:The aim of this study is to detect the expression of EGFRvⅢ and CXCR4 in HNSCC and to explore its possible mechanism. Method:We selected 60 cases of HNSCC from May 2013 to November 2016 in our hospital for surgical treatment, including 44 cases of laryngeal squamous cell carcinoma, 14 cases of hypopharyngeal squamous cell carcinoma, and 2 cases of nasal squamous cell carcinoma. pTNM staging according to AJCC 2010, Ⅲ stage 17 cases, Ⅳa stage 40 cases, and Ⅳb stage 3 cases; according to tumor differentiation degree: 13 cases of high differentiation, moderately differentiation in 31 cases, and 16 cases of low differentiated; primary tumor, positive lymph node metastasis as the experimental group, and 10 cases of adjacent tissues are taken as control (control group). The expression of EGFRvⅢ and CXCR4 in primary tumor, metastasis and control group was observed by immunohistochemistry. The immunohistochemical results are semi quantitatively analyzed by Image-Pro Plus. All analyses were conducted using the SPSS 23.0 and Graphpad-Prism 5.0. Result:The expression of EGFRvⅢ and CXCR4 in HNSCC is higher than control, which was not correlated with age, gender, location, degree of differentiation, T grading, and TNM stage (P>0.05...Continue Reading
