Abstract

Background: The Japanese classification of pancreatic cancer, seventh edition, has been released by Japan Pancreas Society (JPS) in July 2016.

Methods: Revision concepts and major revision points of the seventh edition of Japanese classification of the pancreatic cancers were reviewed.

Results: The principal points of revision are as follows:
  1. 1.

    Definition of the parts of the pancreas.

     
  2. 2.

    T category and stage grouping: consistency with those of the UICC seventh edition was obtained.

     
  3. 3.

    Reappraisal of anatomy of extrapancreatic nerve plexuses.

     
  4. 4.

    N category: classification based on numbers of lymph nodal metastasis among the regional lymph nodes; N1a, metastasis in one to three regional lymph nodes; and N1b, metastasis in four or more regional lymph nodes.

     
  5. 5.

    Histopathological classification which is consistent with the WHO classification.

     

The following new items have been added: (1) diagnostic guideline of tumor extension and lymph node metastasis based on multidetector CT (MD-CT), (2) objective criteria defining resectability status only based on the findings of MD-CT, (3) cytopathology guideline, and (4) criteria of histological response to drug therapy and/or radiotherapy.

Conclusion: The revised seventh edition of JPS pancreatic cancer classification focuses on establishing consistency to UICC seventh edition, while originality of JPS classification is maintained.
