Nanomedicine tactics in cancer treatment: Challenge and hope

Abstract

Defeating cancer is the ultimate challenge and goal of oncologists, facing various obstacles along with finding effective anti-cancer therapies and understanding drug delivery mechanisms. Additionally, the translation of the experimental findings to the clinical outcomes such as specificity, delivery, toxicity, clearance, and bioavailability is another health concern. Nanomedicine is a branch of nanotechnology that has been drastically developed in the last decades. Due to the fact of various nanomaterial formulas, different nanomedicine drug delivery tactics have been developed as anti-cancer therapies. The most effective and less toxic approaches involved the active targeting drug delivery tactic, which relies on the recognition of the drug nanoparticle carriers and the cell surface marker. Accordingly, FDA approved such a group of nanomedicine drug delivery systems while other formulas are still under the clinical trial phases. Nanomedicine is showing a bright future in the treatment of cancer. Oncologists learned from cancer research the possible drug resistance that could be developed. Consequently, researchers need to be prepared for the possible adverse effect of the nanomedicine approach.
