Abstract
Salivary gland carcinomas are rare, characterized by a diversity of histological subtypes associated with variable clinical behavior and prognosis with usually a poor response to chemotherapy. In this context, molecular alterations have been identified and represent potential therapeutic targets: overexpression of human epidermal growth factor receptor 2 (HER2) and androgen receptors in salivary duct cancer, NOTCH mutations in adenoid cystic carcinoma, NTRK gene fusion in secretory carcinoma. Screening for these molecular alterations is mandatory in all patients with recurrent or metastatic salivary gland cancer as it may allow an individualized treatment.
