Base on the American Cancer Society (ACS) report, after diagnosis, only 1 percent of all patients who diagnosed with stage 4 will survive the full 5 years. The prognosis for stage 4 pancreatic cancer is unclear and hard to be done.

It is identified as stage 4 if the cancer has metastasized to other organs or tissue, such as the lungs, stomach, spleen, liver, and/or the bowel. Sometimes it can only be known that a pancreatic cancer is in Stage 4 after the surgery is finished.

This stage 4 is divided into two sub-stages:

  1. Stage 4A – The pancreatic cancer is locally confined, but involves adjacent blood vessels, thereby or organs hindering surgical treatment. This stage of pancreatic cancer is also referred to as locally advance.
  2. Stage 4B – The disease has travel to distant organs or tissue and most commonly the liver. Stage 4B pancreatic cancer is also known as metastasis.

The stage 4 cancer prognosis way is not exact, as it is challenge to identify the symptoms which may lead to the end stage of pancreatic cancer.
