Pancreatic cancer is one of the few cancers for which survival has not improved substantially over nearly 40 years.

Survival Rates with Pancreatic Cancer. Overall, about 5% of patients with cancer of the exocrine pancreas will be alive 5 years after the cancer is found. Even for those with local disease (it has not spread to other organs) the 5-year relative survival rate is only 16%.For those who have regional disease (the cancer has spread to nearby organs and tissues but not farther away), the 5-year relative survival rate is 7%.ven for those with local disease (it has not spread to other organs) the 5-year relative survival rate is only 16%.
