Survival statistics for pancreatic cancer
Survival statistics for pancreatic cancer are very general estimates and must be interpreted very carefully. Because these statistics are based on the experience of groups of people, they cannot be used to predict a particular person’s chances of survival.
There are many different ways to measure and report cancer survival statistics. Your doctor can explain the statistics for pancreatic cancer and what they mean to you.
Net survival represents the probability of surviving cancer in the absence of other causes of death. It is used to give an estimate of the percentage of people who will survive their cancer.
In Canada, the 5-year net survival for pancreatic cancer is 8%. This means that, on average, about 8% of people diagnosed with pancreatic cancer will survive for at least 5 years.
Survival by stage
Survival varies with each stage of pancreatic cancer. The following factors can also affect survival for pancreatic cancer.
- Pancreatic cancer is aggressive and overall has a poor prognosis.
- Generally, the earlier pancreatic cancer is diagnosed and treated, the better the outcome.
- Often pancreatic cancer is not found until it is at an advanced stage, where the tumour has spread or is not resectable.
- Pancreatic cancer often recurs even after it is completely removed with surgery (resected) and then treated with chemotherapy (called adjuvant chemotherapy).
There are no specific Canadian statistics available for the different stages of pancreatic cancer. The following information comes from a variety of sources and includes statistics from other countries.
Observed survival is the percentage of people with a particular cancer who are alive for a specified period of time after their diagnosis. The 5-year observed survival for pancreatic cancer that is resectable (can be completely removed with surgery) is 15%–20%. This means that 15%–20% of people diagnosed with resectable pancreatic cancer are expected to be alive 5 years after diagnosis. The survival rate is often used when talking about a person’s prognosis. However, observed survival does not consider the cause of death, so people could have died from cancer or from other causes.
Questions about survival
Talk to your doctor about your prognosis. A prognosis depends on many factors, including:
- your health history
- the type of cancer
- the stage
- certain characteristics of the cancer
- the treatments chosen
- how the cancer responds to treatment
Only a doctor familiar with these factors can put all of this information together with survival statistics to arrive at a prognosis.
