Breast cancer left overs one of the greatest common metastasis disease in females. Advanced diagnostic devices and better understanding of tumour biology can extend the better therapeutic outcomes. Nanotechnology is a tool that helps in cancer diagnosis and treatment therapy. Many nanocarriers such as solid lipid nanoparticles, magnetic nanoparticles, nanocrystals, nanogels, nano-lipid nanocarriers, biodegradable nanoparticles, liposomes, and dendrimers are introduced to improve the therapeutic efficacy of antineoplastic agents. Surface modified target drug delivery system has the potential to increase the therapeutic effects and also reduce the cytotoxicity of breast cancer. Different approaches have been explored for treatment of breast cancer. This review describes the recent advances in the development of nanocarriers used for the targeted treatment of breast cancer. It also focuses on etiology, risk factor and conventional therapy of breast cancer. KEYWORDS: Breast Cancer; Nano-carriers; Tumor Targeting; Ligands; Receptor.

Cancer Diagnosis And Therapy

Combination of nanotechnology, biochemistry, chemistry and biotechnology provides the opportunity to design unique nanoparticles for tumor targeting, drug delivery, medical imaging and biosensing. Nanoparticles conjugated with biomolecules such as antibodies, peptides, vitamins and aptamer can resolve current challenges including low accumulation, internalization and retention at the target site in cancer diagnosis and therapy through active targeting. In this review, we focus on different strategies for conjugation of biomolecules to nanoparticles such as inorganic nanoparticles (iron oxide, gold, silica and carbon nanoparticles), liposomes, lipid and polymeric nanoparticles and their application in tumor targeting.

Radiolabeled Peptides

Tumor-targeting peptides have been generally developed for the overexpression of tumor specific receptors in cancer cells. The use of specific radiolabeled peptide allows tumor visualization by single photon emission computed tomography (SPECT) and positron emission tomography (PET) tools. The high affinity and specific binding of radiolabeled peptide are focusing on tumoral receptors. The character of the peptide itself, in particular, its complex molecular structure and behaviors influence on its specific interaction with receptors which are overexpressed in tumor. This review summarizes various strategies which are applied for the expansion of radiolabeled peptides for tumor targeting based on in vitro and in vivo specific tumor data and then their data were compared to find any correlation between these experiments. With a careful look at previous studies, it can be found that in vitro unblock-block ratio was unable to correlate the tumor to muscle ratio and the success of radiolabeled peptide for in vivo tumor targeting. The introduction of modifiers’ approaches, nature of peptides, and type of chelators and co-ligands have mixed effect on the in vitro and in vivo specificity of radiolabeled peptides.
