Changes in pancreatic cancer mortality period patterns and birth cohort patterns in Japan: analysis of mortality data in the period 1968–2002

摘要

Objectives The 5-year survival rate for pancreatic cancer is known to be lower than that for cancer at any other site in the body, and the proportion of pancreatic cancer deaths among all cancer deaths has been increasing in Japan. The aim of this study was to investigate pancreatic cancer mortality in the light of temporal and geographical trends in the 47 prefectures of the country between 1968 and 2002.
