15: Abbreviations and Acronyms for Oncology
Contents
Introduction
This section aims to provide a reference list of abbreviations and acronyms that are frequently used within oncology. As well as many widely used medical abbreviations this text includes abbreviations that have meaning only within oncology, sub-specialities or even particular organisations. No definitive list of standard abbreviations exists therefore it is important to understand the context in which they have been used in. For example "PNET" usually refers to a type of brain tumour, however, within orthopaedic oncology the same abbreviation has been applied to a form of sarcoma. You may also find it useful to have access to a medical dictionary or text-book that contains a list of common abbreviations used within the wider field of medicine.
This list of has been compiled over a number of years and abbreviations have been collected from a wide range of sources including journal articles and conference presentations.
Acknowledgements Thanks to the following who have contributed additional abbreviations to this list; Jane Evans, Kevin Fishwick, Anna Mitchell, Moira Stewart and the staff of the former UKCCSG Data Centre.
