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

Download or read book Conversion of Neoplasms by Topography and Morphology from the International Classification of Diseases for Oncology, Second Edition (ICD-O-2) to International Classification of Diseases for Oncology, (ICD-O) (first Edition and Field Trials) written by Constance L. Percy and published by . This book was released on 1992 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epidemiologists, statisticians, oncologists as well as tumor registrars are interested in studying trends in both incidence and mortality. To be able to compare data from one period to another, it is essential that conversion tables be available so that all data is on the same code. The following conversion (comparison or equivalency) tables are from ICD-O-2 and back to the Field Trial editions and ICD-O-1. These tables are divided into Topography and Morphology. There is only one conversion table for the topography since ICD-O-1 and the Field Trials used the same Topography section. There is also one table for Morphology but with three columns: two for the Field Trials, 1988 and 1986 and one for ICD-O-1. The 1987 Field Trial was exactly the same as the 1988 Field Trial except for three terms in Hodgkin's disease: 9657, 9658 and 9659. In all probability this conversion will not be done on records, although a program on tape will be made on request. This conversion is made to help users see what the equivalent code number(s) was in a Field Trial or ICD-O-1.
