Adenocarcinoma of the pancreas carries a grave prognosis for affected patients. Certain oncogenes (K-ras and HER-2/neu) are mutated in a large proportion of these aggressive tumors. Adenocarcinoma of the pancreas has also been associated with loss of tumor suppressor genes (p53, DPC4, p16/MTS), either by deletion or by mutation and loss of function. Growth factors (EGF, TGF-alpha, HGF) and growth factor receptors (EGF-R, c-met, CCK) are expressed at levels not found in the normal pancreas. Finally, factors important for angiogenesis (FGF, integrins, selectins) are likely to play an important role in the growth and metastasis of clinically relevant tumors. This review attempts to summarize and assimilate current research into the molecular and cellular biology of pancreatic cancer.
