ICD-O-3.2

The IARC/WHO ICD-O Committee¹ has updated the draft ICD-O-3.1 classification, with new morphology codes and terms from the 4^th series of WHO Classification of Tumours (Blue Books). 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.

Both documents have been revised according to the comments received during the consultation period and the final Excel tables are available for download in our Support for registries pages.

The ICD-O-3.2 book in pdf format is in preparation. We would like to thank all registries and individuals for comments provided to the draft versions.
