New approaches in salivary gland carcinoma

Purpose of reviewSalivary gland carcinomas (SGCs) are rare tumors of the head and neck with a wide diversity of histologic subtypes characterized by specific morphological, immunohistochemical, and genetic features as well as particular clinical behavior. Chemotherapy is employed almost exclusively with a palliative aim in patients with metastatic and/or recurrent disease and has demonstrated poor activity.Recent findingsImportant advances have been made in the understanding of the molecular pathogenesis of SGCs. Recent studies using next-generation sequencing and genomic and expression profiling methods have identified several genomic alterations of potential clinical significance. We discuss here the recent and most important advances in SGCs biomarkers and their clinical implication. Last years, immune checkpoint inhibitors (ICIs) have changed the landscape of oncology. We report here the few available data in SGCs.SummaryA strategy based on molecular screening and targeted therapy seems to be the best approach for treating patients with SGCs, in the future. More data on ICI's efficacy and biomarkers of response are required to define the place of immunotherapy in the management of SGCs.
