Utilizing liposomes and lipid nanoparticles to overcome challenges in breast cancer treatment

Various lipid particulate drug delivery systems with liposomes as forefront have attracted increasing attention in cancer treatment, especially breast cancer therapy. Multidrug resistance and off-target cytotoxicity are among major obstacles faced by researchers in this area. To address these problems, various strategies, such as composition modifications, pegylation and attaching the targeting ligands, have been investigated. In this regard, a number of liposomal therapeutics could successfully reach the market and also several preclinical and clinical approaches are ongoing to upgrade lipid particles to multipotential carriers and potentiate their therapeutic efficacies. The current review is mainly concentrated on recent approaches in liposomal drug delivery systems intended for breast cancer therapy, and will have a glance at novel attributed studies based on other particulate lipid carriers.
