International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), which is adapted from ICD-9, is used for coding morbidity in all hospitals, now in the 4th edition. It must be used for coding diagnoses which submit claims for third party payment. There are very slight differences between the two books in the Neoplasm Chapter, but the differences are shown in this book and are compiled in the last section of this book. The Topography Section of ICD-O-2 is based on the malignant neoplasms section, categories C00-C80 of the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10), so there is a close relationship between that and ICD-10. The Morphology Section of ICD-O-2 is a revised and expanded version of the Morphology Section of the ICD-O-1. This conversion has been prepared to help those who wish to compare or convert diagnoses coded according to ICD-O-2 with diagnoses coded according to the ICD-9-(CM). For example, a cancer registry may code its diagnoses by ICD-O-2, whereas the record room in the same hospital referring cases to the cancer registry may have used the ICD-9-(CM) to code its case material.

Confronted with myriads ofTs, N's and M's in the VICC TNM booklet, classifying a malignancy may seem to many cancer clini cians a tedious, dull and pedantic task. But then when he looks into the TNM-Atlas all of a sudden lifeless categories become vi vid images, challenging his know-how and his investigational skills. Prof. Dr. Brigit van der Werf-Messing, Chairman of the International TNM-Committee of the VICC. Preface In 1938 the League of Nations Health Organization published an "Atlas illustrating the division of cancer of the uterine cervix into four stages according to the anatomo-clinical extent of the growth". Since this work appeared, the idea of visual representation of the anatomical extent of malignant tumours at the different stages of their development has been repeatedly discussed. At its meeting in Copenhagen in July 1954, the VICC adopted as part of its programme "the realization of a clinical atlas". However, the time to do the planned illustration work was not ripe until the National Committees and international organiza tions had officially recognized the 28 classifications of malignant tumours at various sites as presented in the 3rd edition of the "TNM Booklet" (1978) edited by M. Harmer. This was all the more important since in 1980, in addition to the "Booklet", a "Brochure of Checklists" edited by A.H. Sellers was made available as a further aid in the practical application of the TNMsystem

Gives specialists in the clinical neurosciences a detailed and authoritative instrument for coding virtually all recognized neurological conditions. Both neurological diseases and neurological manifestations of general diseases and injuries are included in this comprehensive coding tool. The volume is part of a growing family of specialty-based adaptations of ICD-10 which retain the core codes of the parent classification while providing extended detail at the fifth character and beyond. Now in its second edition ICD-NA has been revised to reflect current clinical concepts in the neurosciences as well as the new coding system introduced with ICD-10. The classification was finalized following extensive consultation with numerous professional organizations and international experts thus ensuring the representation of as many viewpoints as are practical and consistent. While remaining directly compatible with ICD-10 ICD-NA offers clinicians and researchers much greater precision allowing them to match an explicit diagnosis with a detailed code at the five- six or seven-character level. In addition a comprehensive alphabetical index and the extensive use of inclusion and exclusion terms provide considerable assistance in finding the correct category for any condition diagnosed. Apart from these opportunities for recording greater diagnostic detail the direct compatibility with ICD-10 facilitates comparisons between statistics compiled according to ICD-NA and national morbidity and mortality statistics compiled according to ICD-10. These features enhance the flexibility of ICD-NA making it suitable for use in morbidity statistics hospital record indexing and epidemiological research by government and other health agencies collecting statistical data under relatively few main headings or by individual physicians and researchers requiring a convenient tool for indexing their clinical and teaching material in sufficient detail. The revised classification should also facilitate the collection of epidemiological data comparisons of the prevalence of individual neurological diseases and identification of the risk factors for these diseases at both national and international levels. In addition to the detailed tabular list of neurological and related disorders the volume includes an explanation of the basic principles of classification and instructions for coding morphology codes for neoplasms relevant to neurology and neurosurgery and a 90-page index of diagnostic terms given in standard or official nomenclatures together with synonyms and eponyms.

This edition of ICD-O, the standard tool for coding diagnoses of neoplasms in tumour and cancer registrars and in pathology laboratories, has been developed by a working party convened by the International Agency for Research on Cancer / WHO. ICD-O is a dual classification with coding systems for both topography and morphology. The book has five main sections. The first provides general instructions for using the coding systems and gives rules for their implementation in tumour registries and pathology laboratories. Section two includes the numerical list of topography codes, which remain unchanged from the previous edition. The numerical list of morphology codes is presented in the next section, which introduces several new terms and includes considerable revisions of the non-Hodgkin lymphoma and leukaemia sections, based on the WHO Classification of Hematopoietic and Lympoid Diseases. The five-digit morphology codes allow identification of a tumour or cell type by histology, behaviour, and grade. Revisions in the morphology section were made in consultation with a large number of experts and were finalised after field-testing in cancer registries around the world. The alphabetical index gives codes for both topography and morphology and includes selected tumour-like lesions and conditions. A guide to differences in morphology codes between the second and third editions is provided in the final section, which includes lists of all new code numbers, new terms and synonyms added to existing code definitions, terms that changed morphology code, terms for conditions now considered malignant, deleted terms, and terms that changed behaviour code.

A basic textbook addressed to medical and public health students, clinicians, health professionals, and all others seeking to understand the principles and methods used in cancer epidemiology. Written by a prominent epidemiologist and experienced teacher at the London School of Hygiene and Tropical Medicine, the text aims to help readers become competent in the use of basic epidemiological tools and capable of exercising critical judgment when assessing results reported by others. Throughout the text, a lively writing style and numerous illustrative examples, often using real research data, facilitate an easy understanding of basic concepts and methods. Information ranges from an entertaining account of the origins of epidemiology, through advice on how to overcome some of the limitations of survival analysis, to a checklist of questions to ask when considering sources of bias. Although statistical concepts and formulae are presented, the emphasis is consistently on the interpretation of the data rather than on the actual calculations. The text has 18 chapters. The first six introduce the basic principles of epidemiology and statistics. Chapters 7-13 deal in more depth with each of the study designs and interpretation of their findings. Two chapters, concerned with the problems of confounding and study size, cover more complex statistical concepts and are included for advanced study. A chapter on methodological issues in cancer prevention gives examples of epidemiology's contribution to primary prevention, screening and other activities for early detection, and tertiary prevention. The concluding chapters review the role of cancer registries and discuss practical considerations that should be taken into account in the design, planning, and conduct of any type of epidemiological research.
