title: Flavonoids in oral cancer prevention and therapy.
abstract: Oral cancer, representing all the malignancies arising in the oral cavity, is the eighth most diffused neoplasm worldwide. Despite therapeutic improvements, its survival rate has not changed significantly over the past few decades, with a 5-year survival rate slightly above 50%. In this context, a search for new therapeutic strategies is mandatory. Flavonoids, polyphenolic compounds derived from plants, have a broad spectrum of biological activities, including antioxidant and anticancer. They have been proved to counteract the growth of several types of cancer through multiple mechanisms including the inhibition of cell cycle progression, apoptosis induction, and the modulation of intracellular pathways. Because of their multiple biological activities and their safe toxicological profile, flavonoids have been studied widely in the last decade as potential leads for anticancer therapy. Several studies have reported different flavonoid effects according to cancer cell type. In the present review, therefore, we have evaluated the data available on the effect of flavonoids on oral cancer, with the aim of identifying the molecular mechanisms underlying their potential anticancer properties.
