Integrins in Head and Neck Squamous Cell Carcinoma (HNSCC): A Review of the Current Literature

Integrins are a family of adhesion molecules performing a major role in multiple cellular functions. Their contribution in carcinogenesis and metastatic process are the object of intense research activity worldwide during the last decades. This review focuses on the existing knowledge about integrin expression in head and neck squamous cell carcinoma (HNSCC) as it has been acquired mainly by immunohistochemical methods and by in vitro assays. The elucidation of the exact role of integrins and the study of expressive alterations of these molecules in cancer cells, may result in novel therapeutical approaches for useful applications in the clinical routine of HNSCC in the future.
