Abstract:
The efficacy of current multimodal therapeutic strategies in spinal cord tumors is limited by the lack of specific therapies. Importantly, sufficient amount of therapeutic materials should be concentrated in tumors in order to be efficient. Overcoming the blood-brain barrier is the major obstacle for chemotherapeutics, which cannot reach the tumor bed in efficacious doses. The intrinsic properties of nanoparticles make them suitable for activating numerous processes both at the cellular and subcellular levels, making them good candidates to be used for different purposes in medicine. Furthermore, the adaptability characteristic of NPs may enable them to pass through the blood-brain barrier and transport different pharmacological compounds. Nanoparticle systems provide prolonged drug delivery directly to the tumor or by functionalizing the material surface with peptides and ligands allowing the drug-loaded material to specifically target the tumor cells. In this chapter, various preclinical and/or clinical studies in treatment of spinal cord tumors are discussed.
