The pancreatic cancer stage plays a role in the pancreatic cancer prognosis. Based on historical data:
•7 percent of pancreas cancer cases are diagnosed while the cancer is still confined to the primary site (localized stage)
•26 percent of pancreas cancer cases are diagnosed after the cancer has spread to regional lymph nodes or directly beyond the primary site
•52 percent of pancreatic cancer cases are diagnosed after the cancer has already metastasized (distant stage)
•14 percent of pancreatic cancer cases had staging information that was unknown.
The corresponding five-year relative survival rates were:
•16.4 percent for localized
•7.0 percent for regional
•1.8 percent for distant
•4.3 percent for unstaged.
