Abstract

Head and neck squamous cell carcinoma (HNSCC), the eighth most common cancer worldwide, accounts for approximately 600,000 new cases per year. The mobile tongue is the most common site for oral cancer and is associated with a poorer survival than other HNSCC sites. Standard therapeutic strategies have failed to significantly improve survival rates that have remained around 50% over the past four decades. In the last decade intense investigations on oral cancer highlighted the mandatory role of the tumor microenvironment (TME), in addition to the genetic aberrations and molecular biology changes within the cancer cells. Furthermore, the molecular crosstalk between cancer cells and TME components (i.e., cancer-associated fibroblasts, inflammatory pro-tumorigenic cells, etc.) has a crucial role in growth, invasion, spread and metastases of the cancer cells and consequently leads to poor prognosis. Recent studies suggest that plant-derived dietary agents nutraceuticals, especially curcumin and green tea, have the advantage to combat both malignant cells and TME components, unlike standard anti-cancer protocols that target only cancer cells. However, due to a very low bioavailability, nutraceuticals do not currently constitute an integral part of these protocols. Ongoing developments in nanotechnology for improved delivery are expected to overcome their challenging pharmacokinetics.
