Despite a relatively stable incidence rate, pancreatic cancer casts a disproportionately long shadow, accounting for a sobering 7% of all cancer deaths in the U.S. while representing only 3% of diagnoses.
Key Takeaways
- In 2023, approximately 64,050 new cases of pancreatic cancer were diagnosed in the United States
- Globally, pancreatic cancer accounts for about 4.5% of all cancer deaths, with 466,003 deaths reported in 2020
- The age-adjusted incidence rate of pancreatic cancer in the US is 12.6 per 100,000 men and women per year based on 2017–2021 rates
- Smoking increases pancreatic cancer risk by 20% among current smokers compared to never smokers
- Type 2 diabetes diagnosed 3 or more years before increases risk by 2-fold
- Chronic pancreatitis raises risk 16.1-fold (95% CI 11.73-22.16)
- Jaundice occurs in 70-80% of patients with pancreatic head tumors
- Abdominal pain is present in 80% of pancreatic cancer patients at diagnosis
- Weight loss reported in 62% of patients prior to diagnosis
- Only 20% of pancreatic cancers are resectable at diagnosis
- 5-year survival for localized pancreatic cancer is 44.3% (2013-2019)
- Gemcitabine plus nab-paclitaxel median survival 8.5 months vs 6.7 for gemcitabine alone
- The 5-year survival rate for all stages of pancreatic cancer combined is 12.5% (2013-2019)
- Median survival for metastatic pancreatic cancer is 6-11 months with chemotherapy
- Pancreatic cancer is the third leading cause of cancer death in the US, projected to be first by 2030
Despite steady U.S. incidence rates, pancreatic cancer remains highly lethal.
