Abstract excerpt
BACKGROUND: Our objective was to identify the expression of epidermal growth factor receptor (EGFR), c-KIT (CD117), and HER2/neu in sinonasal undifferentiated carcinoma (SNUC). METHODS: Immunohistochemistry for c-KIT (CD117), EGFR, and HER2/neu was performed on paraffin-embedded tissue from SNUC cases. A search for activating mutations in c-kit exons 9, 11, 13, and 17 or gene amplification was undertaken by...
