Paper Abstract

Despite the significant improvement in the treatment paradigm of head and neck cancer, owing to advanced radiation techniques in combination with chemotherapy, resistance of tumors remains a critical problem, leading to poor outcomes and negative prognosis. In addition, chemotherapeutic agents result in severe systemic toxicity due to nonselective damaging of normal cells. Recently, nanoparticle-based approaches have gained broad attention for improving both radiation therapy and chemotherapy. In this study, we present a dual effect nanoplatform, consists of gold nanoparticles coated with glucose and cisplatin (CG-GNPs), which simultaneously acts as a radiosensitizer and as a carrier which specifically deliver cisplatin to head and neck tumor. Our CG-GNPs showed significant penetration into tumor cells and similar cellular toxicity as cisplatin alone. Moreover, in combination with radiation treatment, CG-GNPs led to greater tumor reduction than that of free cisplatin with radiation. Furthermore, our CG-GNPs also demonstrated highly efficient imaging capabilities, as they act as ideal tumor-targeted CT contrast agent. Therefore, this single nano-formulation is a promising theranostic agent that has the potential to increase the antitumor effect and allow imaging guided therapy.
