Pancreatic cancer is one of the few cancers for which survival has not improved substantially over nearly 40 years. Pancreatic cancer has the highest mortality rate of all major cancers. 91% of pancreatic cancer patients will die within five years of diagnosis â only 9% will survive more than five years.
The median survival duration from the time of diagnosis until demise is arguably the worst of any of the cancers â certainly of the major cancers. The median survival for untreated advanced pancreatic cancer is about 3 1/2 months; with good treatment this increases to about six months, though many will live much longer.We have encountered nine and ten year survivors.he median survival duration from the time of diagnosis until demise is arguably the worst of any of the cancers â certainly of the major cancers.
