Trends in pancreatic adenocarcinoma incidence and mortality in the United States in the last four decades; a SEER-based study

Pancreatic cancer is the fourth-leading cause of cancer deaths in the United States. The silent nature of the disease and its poor prognosis, the need for further research, along with the need to assess the outcomes of current approaches necessitate an ongoing evaluation of the epidemiology and mortality-trends of this malignancy.
