Breast Cancer: From Bench to Personalized Medicine

Abstract

Despite considerable advances in chemotherapeutics, mortality rate of breast cancer is still on the rise. This is largely due to shortcomings associated with chemotherapeutics medicines. Firstly, majority of medicines lack specificity, second most of them get solubilized before reaching the target resulting in reduced bioavailability of drug at target site. Introduction of nanotechnology in medicine offers some promising solutions. Since nanoparticles have small size with at least one dimension less than 100 nm, they have unique interaction with biological systems at molecular level. Their large surface to volume ratio gives an excellent opportunity to manipulate them for desired properties, i.e., targeting cancer cells, loading drug and genetic materials, controlled release, increasing cellular uptake thereby increasing selectivity and bioavailability to target site. By targeting cancer cells, nanomedicine can help in reducing effects of systemic toxicity of chemotherapeutic drugs. Both metallic and non-metallic nanoparticles are currently studied as emerging therapeutic platforms against breast cancer therapy. Not only this, but nanoparticles can also be used as a platform to construct a delivery system where therapeutics and diagnostics can be integrated leading to the development of theranostic (Therapy + Diagnostic) nanoparticles. In this chapter, we have discussed in detail the potential of these nanoparticle-based treatment, its pharmacokinetics, their mechanism of controlled release, and their application as theranostic agents in breast cancer.
