Novel gene therapy approaches to pancreatic cancer.

One of the most lethal human malignancies, pancreatic adenocarcinoma has remained a therapeutic challenge. Historically, the only curable treatment modalities available to patients with this disease have included pancreaticoduodenectomy with adjuvant chemoradiation. Few patients, however, have resectable disease at the time of presentation, and even for those who are offered this radical course of treatment, post-surgical survival is dismally short. Recently, however, advances in the understanding of the molecular biology of pancreatic cancer have enabled researchers to investigate novel gene therapy approaches to the treatment of this disease. In this paper, we review the common genetic mutations found in pancreatic adenocarcinomas, discuss strategies for the manipulation of genetic targets, and assess current progress in the field of gene therapy as it relates to pancreatic cancer.
