APPENDIX G:

RECOMMENDED ABBREVIATIONS FOR ABSTRACTORS

Even in the age of computerized abstracts with coded fields, text is still required to supplement and support coded information. In writing this text, registrars rely on abbreviations, especially in response to time and record space constraints. Abbreviations can generate confusion, however, as they may vary among different institutions and different specialties. Because abbreviations should be understood by any reader, only those that are clear and precise should be used. The NAACCR Recommended Abbreviations Lists, below, were compiled for cancer abstractors and the agencies to which they submit their data.


These consist of two main lists of over 600 words/terms and their recommended abbreviations/symbols, as well as a special table of context-sensitive abbreviations. The first list is ordered by the words/terms for which an abstractor seeks an abbreviation, and the second is ordered by abbreviation/symbol, paired with the complete word or term. The context-sensitive abbreviations table consists of a subset of the abbreviations, for which a different context for the same abbreviation conveys a different meaning (for example, CA may mean calcium or carcinoma, and ML may mean milliliter or middle lobe). For these context-sensitive abbreviations, the meaning of the abbreviation should be readily apparent from its context.
