ICD-O-3.2 TABLES
The IARC/WHO ICD-O Committee1 has updated the draft ICD-O-3.1 classification, with new morphology codes and terms from the 4th series of WHO Classification of Tumours (Blue Books).
The new version, ICD-O-3.2, is recommended for use from 2020.
The IACR Working Group on ICD-O Updates2 has compiled a listing of additions, changes and revisions between ICD-O-3.1 and ICD-O-3.2 as a reference material for cancer registries.
These documents have been revised according to the comments received during the consultation period and the final tables are available for download here:

As it is no longer possible to maintain and update the previous http://codes.iarc.fr website, it was decommissioned on 31 July 2019. IARC is updating its web domain and it is not possible to maintain this website on the new platform. We apologize for any inconvenience as a result of the decommissioning.
