Conversion of Neoplasms by Topography and Morphology from the InternationalClassification of Diseases for Oncology (ICD-0) (First Edition and Field Trials) to International Classification of Diseases for Oncology, Second Edition (ICD-0-2)

摘要

The International Classification of Diseases for Oncology, Second Edition (ICD-O-2) (1) was published by the World Health Organization (WHO) in 1976. Since the topography section is based on the Neoplasm chapter of the current revision of the International Classification of Diseases (ICD), whenever that classification is revised the ICD-O topography section must also be changed. Therefore in conjunction with the revision of the International Classification of Diseases, Ninth Revision (ICD-9), to the International Classification of Diseases and Related Health Services, Tenth Revision (ICD-10) the topography section of ICD-O was also revised. In addition the Morphology section of ICD-O was updated to conform to modern terminology. For example, the Non-Hodgkin's Lymphoma section is now based on the Working Formulation. In the process of revising the Morphology section three Field Trial versions were published. The first field trial was published in 1986 (5), the second in 1987 (6), and the third in March of 1988. The International Classification of Diseases for Oncology, Second edition (ICD-O-2) was published by WHO in 1990.
