Reviewing the ICD-10 classification of haematological neoplasms on its way to ICD-11
At the WHO Family of International Classifications (WHO-FIC) Network Meeting 2004 (Reykjavik, Iceland) it was agreed that the German centre, as others, takes part in reviewing ICD-10 in distinct areas which were identified as crucial and representative for other sections .
As areas for reviewing the evidence of ICD-10 and starting the process cystic fibrosis, diabetes, lymphomas, external causes and mental health were identified.
The German Collaborating Centre (CC) took responsibility for reviewing the section of leukaemias and lymphomas.
Main issues regarding the classification of haematological neoplasm in ICD-10 are:
differences between ICD-10 and ICD-O-3 concerning the structure
differences between ICD-10 and ICD-O-3 concerning the content
differences between ICD-10, ICD-O-3 and the current state of science
limitations due to the updating of ICD-10
This document will explain methods and results.
