Evaluation of the Efficacy of Saracatinib-Loaded Nanoparticles in Lymphatic Metastases of HNSCC with the Aid of Bioluminescence Imaging.

Abstract

Head and neck squamous cell carcinoma (HNSCC) remains a deadly disease despite concerted efforts to improve its diagnosis and treatment in recent decades. Metastasis of advanced HNSCC nearly always occurs first in neck lymph nodes before the development of distant metastasis. However, the development of preclinical animal models and therapeutic treatments for metastatic HNSCC is lagged from bench to clinic. In this protocol, we exemplify an orthotopic tongue tumor model that can recapitulate the cervical lymphatic metastases of HNSCC and the application to study the effect of novel saracatinib-loaded nanoparticles (Nano-Sar). By taking advantage of bioluminescence imaging (BLI), the present protocol reveals the strong anti-metastatic efficacy of Nano-Sar in the experimental setup. Collectively, the protocol with a novel metastatic mouse model shows great potential to evaluate treatments on metastatic diseases with the aid of bioluminescent technology.
