Technology Description
According to the American Academy of Otolaryngology, more than 55,000 Americans will develop cancer of the head, and nearly 13,000 of them will die this year from it.[1] Improved treatments are desperately needed. In conventional radiotherapy, there is a delicate challenge to deliver a high therapeutic radiation dose to the tumor without affecting the surrounding healthy tissues. “Dose enhancement at interfaces between high and low atomic number (Z) materials has been studied for over 50 years.”[2] “High-Z elements absorb X-rays and increase local dose,”[3] Nanoprobes has extended this concept and is developing Nanogold (novel gold nanoparticle) for enhanced-radiotherapy. “In preliminary studies, high levels of gold specifically accumulated in tumors after intravenous injection of Nanogold. X-ray irradiation then resulted in dramatic tumor regressions and long term survivals (86%, >1yr) in mice compared with mice irradiated without Nanogold (20%).
