Pancreatic cancer (PC) is the fourth leading cause of cancer death in men and fifth in women in the US (Jemal, Sigel, Ward, Murray, Xu, Thun et al., 2007). According to the American Cancer Society, the reported incidence of PC is roughly 37,000 cases per year, with approximately 33,000 annual deaths (2007). Periampullary cancers are less common; there were 9,250 incident cancers of the biliary tract in 2007, with 3,250 resultant deaths (Jemal et al., 2007).
