Pancreatic cancer is one of the most lethal malignancies. Significant progresses
have been made in understanding of pancreatic cancer pathogenesis, including
appreciation of precursor lesions or premalignant pancreatic intraepithelial
neoplasia (PanINs), description of sequential transformation from normal
pancreatic tissue to invasive pancreatic cancer and identification of major
genetic and epigenetic events and the biological impact of those events on
malignant behavior. However, the currently used therapeutic strategies targeting
tumor epithelial cells, which are potent in cell culture and animal models, have
not been successful in the clinic. Presumably, therapeutic resistance of
pancreatic cancer is at least in part due to its drastic desmoplasis, which is a
defining hallmark for and circumstantially contributes to pancreatic cancer
development and progression. Improved understanding of the dynamic interaction
between cancer cells and the stroma is important to better understanding
pancreatic cancer biology and to designing effective intervention strategies.
This review focuses on the origination, evolution and disruption of stromal
molecular and cellular components in pancreatic cancer, and their biological
effects on pancreatic cancer pathogenesis.
