Receiving a pancreatic cancer diagnosis can be overwhelming, and it’s natural to have pressing questions about what the future holds. Understanding the average length of life after a pancreatic cancer diagnosis is a critical concern for patients and their loved ones. While pancreatic cancer is often diagnosed at an advanced stage, impacting the prognosis, it’s essential to approach survival statistics with a balanced perspective. These figures, based on large populations, provide valuable insights but cannot predict the outcome for an individual. This detailed guide aims to clarify pancreatic cancer survival rates, drawing upon current research to offer a comprehensive understanding of what these statistics indicate across different stages and types of pancreatic cancer.
Survival in pancreatic cancer is influenced by numerous factors, and it’s crucial to remember that statistics are general and do not dictate individual experiences. Consulting with your healthcare provider is paramount for personalized information regarding your specific prognosis. For additional support and information, resources like the Cancer Research UK information nurses are available to offer guidance and answer questions.
Interpreting Survival Statistics in Pancreatic Cancer
Terms like 1-year, 3-year, and 5-year survival rates can be initially confusing. These terms are statistical benchmarks that represent the percentage of people who are still alive at these intervals after their diagnosis, not that patients will only live for that duration. Medical researchers use these timeframes to assess the effectiveness of treatments and the progression of the disease across large groups of patients. Five-year survival, in particular, is a commonly used metric, but many individuals with pancreatic cancer live significantly longer than five years post-diagnosis.

Survival Rates by Stage of Pancreatic Cancer
Pancreatic cancer is predominantly exocrine, originating in the cells responsible for digestive enzyme production. The survival statistics presented here focus on exocrine pancreatic cancers and exclude pancreatic endocrine tumors, which have different survival patterns discussed later.
The data presented below is derived from a comprehensive study analyzing cancer registries across seven countries, including the UK (excluding Scotland due to data inconsistencies), and represents diagnoses made between 2012 and 2014. Pancreatic cancer staging is categorized into localized, regional, and distant, which may correlate with the numerical staging (stage 1 to 4) used by clinicians. If you are unsure about your cancer stage, it is important to discuss this with your specialist for clarity.
-
Localized Pancreatic Cancer: In localized cancer, the tumor is confined to the pancreas without spreading to distant sites.
- 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: Regional cancer indicates that the cancer has spread to nearby lymph nodes surrounding the pancreas.
- About 50% of individuals with regional pancreatic cancer survive for at least one year.
- Roughly 15% of individuals with regional pancreatic cancer survive for three years or more.
-
Distant Pancreatic Cancer: Distant cancer signifies that the cancer has metastasized to other parts of the body, away from the pancreas.
- Around 10% of individuals with distant pancreatic cancer survive for at least one year post-diagnosis.
- Only about 1% of individuals with distant pancreatic cancer survive for three years or more.

Source of Staging Data: These statistics are based on data from over 35,000 pancreatic cancer patients across Australia, Canada, Denmark, Ireland, New Zealand, Norway, and the UK, diagnosed between 2012 and 2014. The study, “Pancreatic cancer survival by stage and age in seven high-income countries (ICBP SURVMARK-2): a population-based study,” published in the British Journal of Cancer in March 2022, provides a detailed analysis of these survival outcomes. These figures represent net survival, which estimates cancer-specific survival by accounting for deaths from other causes.
Overall Survival Rates for All Stages of Pancreatic Cancer
While stage-specific survival rates are informative, understanding the overall survival for all stages combined provides another perspective. For adults diagnosed with pancreatic cancer in England:
- Nearly 30% survive for at least one year after diagnosis.
- Almost 10% survive for five years or more.
- It is estimated that approximately 5% survive for ten years or more.

The relatively lower overall survival rates in pancreatic cancer are partly due to late diagnosis, as the disease often presents at an advanced stage. Surgical removal of the tumor, which offers the best chance of a cure, is only feasible in about 10% of cases.
Source of Overall Survival Data: The 1-year and 5-year survival statistics are derived from “Cancer survival in England, cancers diagnosed 2016 to 2020, followed up to 2021,” NHS England. The 10-year survival data comes from “Cancer survival in England: adult, stage at diagnosis and childhood – patients followed up to 2018,” Office for National Statistics. These statistics also represent net survival, providing a cancer-specific survival estimate.
Survival Rates for Pancreatic Endocrine Tumors (NETs)
Pancreatic endocrine tumors, also known as neuroendocrine neoplasms (NENs), represent a less common type of pancreatic cancer. These tumors generally have a more favorable prognosis compared to adenocarcinoma, the most common type of exocrine pancreatic cancer.
-
1-Year Survival for Pancreatic NETs: Approximately 80% of individuals with pancreatic NETs survive for at least one year.
-
5-Year Survival for Pancreatic NETs: Although UK-wide 5-year survival statistics are not available, European studies indicate that around 40% of individuals with pancreatic NETs survive for five years or more. It is important to note that these European figures may vary from UK outcomes due to differences in healthcare systems and data collection.

Source of NETs Survival Data: The 1-year survival rate for pancreatic NETs is based on a Public Health England study of 1,415 patients diagnosed between 2013 and 2015, detailed in the “Impact of neuroendocrine morphology on cancer outcomes and stage at diagnosis: a UK nationwide cohort study 2013–2015,” published in the British Journal of Cancer in 2019. The 5-year survival data originates from a European study involving 1,635 patients diagnosed between 1995 and 2002, as part of the “Rare neuroendocrine tumours: Results of the surveillance of rare cancers in Europe project,” published in the European Journal of Cancer in 2013. These 5-year survival statistics are relative survival rates, accounting for deaths from other causes to provide a more accurate cancer-specific survival estimate.
Factors Influencing Pancreatic Cancer Survival
Survival rates in pancreatic cancer are not solely determined by stage. Several factors play a crucial role in influencing an individual’s prognosis:
- Stage at Diagnosis: As highlighted, the extent of cancer spread is a primary determinant of survival. Earlier diagnosis at a localized stage significantly improves the chances of longer survival.
- Type and Grade of Cancer: The specific type of pancreatic cancer (exocrine vs. endocrine) and the grade of cancer cells (how abnormal they appear) affect prognosis. Lower grade tumors typically grow slower and have a better outlook.
- Overall Health and Fitness: A patient’s general health, fitness level, and ability to tolerate treatment significantly impact survival. Better overall health can improve resilience and response to cancer therapies.
- Treatment Received: Access to and effectiveness of treatments, including surgery, chemotherapy, and radiation therapy, are critical factors in survival outcomes.
