RECOMMENDED ABBREVIATIONS FOR ABSTRACTORS

The use of abbreviations in cancer abstraction is becoming more commonplace as the demands on abstractors increase. Abbreviations often are used by cancer abstractors to shorten the written narratives entered into text fields to facilitate the electronic storage and transmission of the information. However, abbreviations can generate confusion, because abbreviations may vary among different institutions and even between different specialties within the same institution. To be useful, an abbreviation must be clearly understood by any individual who encounters it. Consequently, the use of abbreviations is a useful abstracting practice only if universally recognized and understood abbreviations are used.

The NAACCR Recommended Abbreviations Listings were developed for utilization by cancer report abstractors and the agencies to which they submit their data. These lists were compiled to reduce some of the confusion that can result from the use of common and not-so-common abbreviations when abstracting reports of cancer from the medical record. Although the lists may shed some light on abbreviations used in the medical record, please note that these lists are intended to be used as a primary reference by the cancer abstractor, to help abstract necessary information into a limited number of text fields for storage and transmission of cancer information.

The NAACCR Recommended Abbreviations Listings consist of two main lists of almost 500 word/terms and their recommended abbreviations/symbols, as well as a special table delineating context-sensitive abbreviations. The first main listing is ordered by word/term to enable the look-up of a recommended abbreviation for a particular word or term, and the second main listing is ordered by abbreviation/symbol to enable the look-up of the word or term for a particular abbreviation or symbol. The context-sensitive abbreviations list consists of a subset of the abbreviations from the main lists where a different context for the same abbreviation conveys a different meaning (for example, CA may mean calcium or carcinoma/ML may mean milliliter or middle lobe). For these context-sensitive abbreviations, the meaning of the abbreviation should be readily apparent from the context in which it is used.

The listings were compiled from abbreviation lists from SEER Book 3, the NAACCR Pathology Committee, the Veterans Administration, Dr. Jay Piccirillo’s comorbid conditions training materials, the Florida Cancer Data System, and the California Cancer Registry. Terms included in the lists are limited to those that are commonly utilized when abstracting cancer information. The listings are not exhaustive, but many of the most commonly used terms were included. Abbreviations for chemotherapy drugs and/or regimens are not included. Please note that although abbreviations are presented in uppercase, either upper- or lowercase may be utilized when entering abbreviations within abstraction software. When abstracting into text fields, the use of abbreviations should be limited to those that appear on these lists whenever practical. Abbreviations and symbols should be used carefully.
