Trends in pancreatic cancer incidence in nine SEER Cancer Registries, 1973–2002

Abstract
Background: The evolution of pancreatic cancer incidence in the last three decades in the United States remains unclear. This study was conducted to investigate this problem, using data from the nine registries of the Surveillance, Epidemiology, and End Results (SEER) Program. Patients and methods: The incidence data in 1973–2002 were age standardized to the 2000 USA standard population and analyzed by the joinpoint regression. Results: For the nine registries combined, pancreatic cancer incidence in men significantly decreased by 0.62% per year from 1973 to 2002. Incidence in women increased until 1984 and slowly declined thereafter. A rise in incidence, although not statistically significant, has been noted in young and middle-aged adults (Conclusions: Pancreatic cancer incidence significantly decreased from 1973 to 2002 in men and increased until 1984 and then declined slowly in women in the United States.
