Pancreatic Cancer: Recent Advances in Nanoformulation-Based Therapies.

Abstract

Pancreatic cancer is the fourth leading cause of death in the United States and has a 5-year life expectancy of ~8%. Currently, only a few drugs have been approved by the United States Food and Drug Administration for pancreatic cancer treatment. Despite available drug therapy and ongoing clinical investigations, the high prevalence and mortality associated with pancreatic cancer mean that there is an unmet chemopreventive and therapeutic need. From ongoing studies with various novel formulations, it is evident that the development of smart drug delivery systems will improve delivery of drug cargo to the pancreatic target site to ensure and enhance the therapeutic/chemoprevention efficacy of existing drugs and newly designed drugs in the future. With this in view, nanotechnology is emerging as a promising avenue to enhance drug delivery to the pancreas via both passive and active targeting mechanisms. Research in this field has grown extensively over the past decade, as is evident from available scientific literature. This review summarizes the recent advances that have brought nanotechnology-based formulations to the forefront of pancreatic cancer treatment.
