Pancreatic cancer is a deadly malignancy with still high mortality and poor survival despite the significant advances in understanding,
diagnosis, and access to conventional and novel treatments. Though cytotoxic chemotherapy based on the purine analogue gemcitabine
remains the standard approach in adjuvant and palliative setting the need for novel agents aiming at the main pathophysiological
abnormalities and molecular pathways involved remains soaring. So far, evidence of clinical benefit, though small, exists
only from the addition of the targeted agent erlotinib on the standard gemcitabine chemotherapy. Apart from the popular monoclonal
antibodies and small molecules tyrosine kinase inhibitors, other novel compounds being tested in preclinical and clinical
studies target mTOR, NF-κB, proteasome and histone deacetylase. These new drugs along with gene therapy and immunotherapy,
which are also under clinical evaluation, may alter the unfavorable natural course of this disease. In this review we present
the main pathophysiological alterations met in pancreatic cancer and the results of the florid preclinical and clinical research
with regards to the targeted therapy associated to these abnormalities.
