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:
- 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.
- 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.
