Immuno-therapy for cancer treatment using iron oxide nanoparticles

Abstract

An immuno-therapy for treatment of a tumor is provided. An effective dose of a composition containing a low dose of superparamagnetic iron oxide nanoparticle is administered to a tumor. Once the composition has been administered, it is recommended to avoid any means that would cause direct cytotoxic effects to the cancer cells and to normal/healthy tissue. The combination of composition-administered cancer cells with the avoidance of direct cytotoxic effects has been shown to be successful to inhibit the growth of the cancer cells or result in aptosis of the cancer cells. Additional dose(s) can be administered when it is determined that: (i) the tumor starts to grow and/or (ii) the remaining composition falls below a threshold. The immuno-therapy method is a safe, clinically applicable, ready-to-use theranostic approach for cancer patients who are unable to start chemoradiotherapy in a timely manner, i.e. an effective interim or adjunctive treatment for patients.
