Excerpt
In 1966, WHO convened a meeting of investigators on comparative oncology, at which the participants agreed to start work on developing an international histological classification of tumours of domestic animals in parallel with the classification of human tumours being developed by WHO. The main purpose of the project is to reveal similarities and differences between tuinours in man and in domestic animals and thus provide a sound basis for research in comparative oncology generally; a secondary aim is to help to advance veterinary pathology. A widely accepted standard nomenclature of tumours, based on defined histological criteria, is necessary to avoid misunderstandings in the exchange of information and for collaborative work, such as coordinated epidemiological and therapeutic studies. At present, uniformity in these matters is notably lacking: sometimes one term is used for different tumours and, conversely, the same tuinour may have several names. The need for conformity is felt increasingly with the growth of international collaboration. The frequency and nature of tumours in the various body sites differ enormously among species (including man), breeds, and regions. In most instances these differences have not yet been related to causal or resistance factors. A first requisite in investigating these differences is a standard classification. Classification includes the following steps: (a) identification and description of types, i.e., neoplastic entities as judged mainly by their morphological features, (b) categorization in a logical scheme, and (c) adoption of the most suitable nomenclature. To ensure that the WHO histological classifications of tuinours in man were followed as far as possible, the veterinary pathologists who undertook these tasks consulted pathologists who had worked on those classifications. The basis for classification, as with the human tumours, has been mainly histology, but histogenesis and biological behaviour have been taken into account in some instances. The prccedure has been as follows. For each body site. WHO has designated a collaborating laboratory; this laboratory makes a collection of appropriate tumours and arranges for colleagues to cooperate in this nork. A member of the team concerned with human tumours of the corresponding site is ahrays consulted. A tentative classification is prepared and presented at meetings of the heads of collaborating laboratories for discassion. revision, and eventual approval. There have been six such meetings so far. and most of the classifications presented in this volume were reviewed at several rneet~ngs before being finally agreed upon. A list of those who attended one or more of these meetings appears on pages 7-8.
