Abstract
Pancreatic ductal adenocarcinoma (PDA) has one of the worst prognosis and higher mortality among most cancers. The diagnosis of PDA is frequently delayed due to a lack of specific biomarkers, and the efficacy of current chemotherapeutic drugs is limited. Moreover, chemotherapy is generally applied in advanced stages, where metastatic spread has already occurred. Nanotechnologybased systems are allowing to advance in the diagnosis and treatment of PDA. New nanoformulations have shown to improve the activity of conventional chemotherapeutic agents, such as gemcitabine, and new antitumor drugs, protecting them from degradation, improving their selectivity, solubility and bioavailability, and reducing their side effects. Moreover, the design of nanocarriers represents a new way to overcome drug resistance, which requires a comprehensive understanding of the tumor microenvironment of PDA. This article reviews the current perspectives, based on nanomedicine, to address the limitations of pancreatic cancer treatment, and the futures lines of research to progress in the control of this disease.
Keywords: Pancreatic ductal adenocarcinoma, chemotherapeutic drugs, nanoparticles, drug resistance, clinical trials, gemcitabine.
