The up-to-date review of epidemiological pancreatic XXXX in Japan.

@entity1 @entity6196 @entity788 @entity7582 @entity9608 @entity5 @entity3270 @entity3 @entity7581
@entity788 ( @entity788 ) were considered an extremely rare disease. However, in recent years, the number of @entity1 with @entity6196 has increased rapidly. According to an epidemiological survey conducted in Japan, the number of treated @entity1 with @entity788 in 2010 was approximately 1.2-times that in 2005, and the number of new incidences of non-functional @entity788 in 2010 was approximately 1.7-times that in 2005. Among functional @entity788 , @entity9608 was most prevalent, followed by @entity7581 . To diagnose @entity788 , correct histological diagnosis is most important. According to the World Health Organization 2010 classification criteria, @entity5 ( @entity5 ) are categorized into well-differentiated @entity5 and poorly differentiated @entity3270 ( @entity3270 ). @entity3270 accounted for 7.6% of all @entity5 , and functional and non-functional @entity788 accounted for 2.1% and 10.1%, respectively. @entity1 with distant @entity3 accounted for 19.9%, and those with @entity7582 accounted for 4.3%. When treating @entity788 , it is necessary to correctly evaluate the functionality and progression of @entity5 , the presence or absence of @entity3 , and the degrees of differentiation and malignant potential of @entity5 . A new registration system from the Japan @entity5 Society will start to be used in 2015, which will help further dissemination of Japanese epidemiological information to the world.
