Exocrine pancreatic cancer is rarely curable and has an overall survival (OS) rate of less than 6%.
The highest cure rate occurs if the tumor is truly localized to the pancreas; however, this stage of disease accounts for less than 20% of cases. For patients with localized disease and small cancers (

The 1- and 5-year relative survival rates for persons
with colorectal cancer are 84% and 64%, respectively. Survival
continues to decline to 58% at 10 years after diagnosis. When
colorectal cancers are detected at an early, localized stage, the
5-year survival is 90%; however, only 39% of colorectal cancers
are diagnosed at this stage, in part due to the underuse of screening.
If the cancer has spread regionally to involve nearby organs
or lymph nodes at the time of diagnosis, the 5-year survival
drops to 70%. If the disease has spread to distant organs, the
5-year survival is 12%.
