Pancreatic cancer is frequently detected at an advanced stage, making the prognosis challenging. However, it’s crucial to understand that survival rates are statistics based on large groups and cannot predict individual outcomes. If pancreatic cancer is diagnosed before it has spread, and surgical removal is possible, the outlook is generally more favorable.
Survival rates in pancreatic cancer are influenced by numerous factors, and it’s essential to have personalized discussions with healthcare professionals. These statistics provide a general understanding but don’t dictate individual experiences. For tailored information, consulting your doctor or seeking support from cancer information services is recommended.
Understanding Survival Statistics in Pancreatic Cancer
Terms like 1-year, 3-year, and 5-year survival rates are commonly used in cancer prognosis. These terms do not limit an individual’s lifespan to these specific durations. Instead, they represent the percentage of people who have lived for at least that long after their diagnosis. Researchers use these benchmarks to analyze the effectiveness of treatments and the progression of the disease across large populations. Five-year survival is a standard point of measurement, but many individuals with pancreatic cancer live significantly longer.
Five-year survival rate indicates the proportion of patients who have not died from pancreatic cancer within five years following their diagnosis. It’s a statistical measure to understand the general trends in survival.
Pancreatic Cancer Survival Rates by Stage
Most pancreatic cancers are exocrine, originating in the cells that produce digestive enzymes. The survival statistics discussed here primarily focus on exocrine pancreatic cancer and exclude pancreatic endocrine tumors, which have separate survival data discussed later.
Data from a comprehensive study analyzing cancer registries across seven countries provides the basis for these survival statistics. This study encompassed data collected from hospitals and healthcare providers between 2012 and 2014. While the UK was included, the data specifically represents England, Wales, and Northern Ireland due to data completeness.
Pancreatic cancer staging is categorized into localized, regional, and distant stages. These terms offer a general understanding of cancer spread:
- Localized Cancer: The cancer is confined to the pancreas and has not spread to other areas.
- Regional Cancer: The cancer has spread to nearby lymph nodes surrounding the pancreas.
- Distant Cancer: The cancer has metastasized to distant parts of the body, away from the pancreas.
Localized Pancreatic Cancer Survival Rates
For localized pancreatic cancer, the prognosis is relatively better compared to advanced stages:

- Approximately 55% of individuals with localized pancreatic cancer survive for at least one year after diagnosis.
- Over 25% of individuals with localized pancreatic cancer survive for three years or more.
Regional Pancreatic Cancer Survival Rates
When pancreatic cancer has spread to regional lymph nodes, the survival rates are impacted:

- About 50% of individuals with regional pancreatic cancer survive for at least one year after diagnosis.
- Roughly 15% of individuals with regional pancreatic cancer survive for three years or more.
Distant (Metastatic) Pancreatic Cancer Survival Rates
Distant pancreatic cancer, which has spread to other organs, has the most challenging prognosis:

- Approximately 10% of individuals with distant pancreatic cancer survive for at least one year after diagnosis.
- Only about 1% of individuals with distant pancreatic cancer survive for three years or more.

These statistics represent net survival, estimating cancer-specific survival by accounting for deaths from other causes in the absence of pancreatic cancer. Further details on these statistics are available from Cancer Research UK’s Cancer Statistics section.
Overall Survival Rates for All Stages of Pancreatic Cancer
For all stages of pancreatic cancer combined, the overall survival rates are generally lower due to late diagnosis being common. For adults diagnosed in England:
- Nearly 30% of individuals survive for at least one year post-diagnosis.
- Almost 10% of individuals survive for five years or more.
- It’s estimated that only 5% of individuals survive for ten years or more after being diagnosed with pancreatic cancer.
A primary reason for the lower life expectancy in pancreatic cancer is its late-stage diagnosis. Often, the cancer is already advanced when detected. Surgery, which offers the best chance of a cure, is only feasible in about 10% of cases.

These overall statistics also represent net survival, providing a more accurate picture of cancer-specific survival by considering mortality from other causes.
Survival Rates for Pancreatic Endocrine Tumors (NETs/NECs)
Pancreatic endocrine tumors, now often referred to as neuroendocrine neoplasms (NENs), are a less common type of pancreatic cancer. They are further classified as neuroendocrine tumors (NETs) or neuroendocrine carcinomas (NECs) based on their growth rate. Generally, these tumors have a more favorable prognosis compared to pancreatic adenocarcinoma.

- Approximately 80% of individuals with pancreatic NENs survive for at least one year.
5-Year Survival for Pancreatic NETs/NECs
Five-year survival data for pancreatic NENs in the UK is limited to European studies. It’s important to note that these figures might not fully reflect UK survival rates due to variations in healthcare systems and data collection.
- Around 40% of individuals with pancreatic NENs survive for five years or more after diagnosis.

- 5-year survival: Van de Zwan JM, et al. Rare neuroendocrine tumours: Results of the surveillance of rare cancers in Europe project. European Journal of Cancer, 2013.
These 5-year survival statistics are for relative survival, which adjusts for deaths from other causes, providing a more precise estimate of cancer-specific survival.
Factors Influencing Pancreatic Cancer Survival
Several factors can impact an individual’s prognosis after a pancreatic cancer diagnosis. The stage of the cancer at diagnosis is paramount, indicating the extent of the tumor and its spread. The type and grade of cancer cells also play a significant role, with grade reflecting the abnormality of cells under microscopic examination. Furthermore, a patient’s overall health and fitness level are crucial, as better physical condition can improve tolerance to cancer treatments and the disease itself.
