Current update on established and novel biomarkers in salivary gland carcinoma pathology and the molecular pathways involved.

This review aims to take stock of the new information that has accumulated over the past decade on the molecular pathology of salivary gland cancer. Emphasis will be placed on established and novel immunohistochemical markers, the pathways involved, and on findings of prognostic importance as well as new therapeutic concepts. Whenever reasonable, analogies to tumors of better explored, histologically related glandular organs such as pancreas and breast are established.
