EGFR and adenoid cystic carcinoma: Overexpression of the human epidermal growth factor receptor (HER) family of oncoproteins, HER1/epidermal growth factor receptor (EGFR) and HER2, has been described in approximately 70% of salivary gland carcinomas including MEC and adenoid cystic carcinoma [4] but few studies have evaluated the therapeutic relevance of an anti-EGFR/HER2 strategy in these neoplasms.
