P226 Lack of Exon 19 and 21 EGFR Mutations in Squamous Cell Head and Neck Cancer Specimens and Cell Lines

Arch Otolaryngol Head Neck Surg. 2006;132(8):910. doi:10.1001/archotol.132.8.910-a

Objective: It has recently been reported that epidermal growth factor receptor tyrosine kinase inhibition might be a more effective treatment strategy in patients harboring specific EGFR mutations. These mutations are prevalent in 3% to 7% of non–small-cell lung carcinomas. Our objective was to examine whether these mutations might be more common at other upper aerodigestive cancer sites.

Design: We extracted DNA from 20 head and neck squamous cell tumors and 4 squamous cell carcinoma cell lines and sequenced the receptors using previously published primer pairs. We then compared the results against reported mutations.
