NAACCR Standards – Supporting Text

Standard 3.2.2 – Data Text

Text information should be:

included in the registry’s dataset

transmitted along with codes when tumor records are shared with other registries.

Final abstract

Codes and text provide information on the patient and the patient’s disease

Either should derive the same outcomeText should be concise and pertinent Use only approved abbreviationsCodes provide universal language for

data retrieval

39

Helpful Hints for Abstracting

Document the information that led to the assignment of a particular codeC619 – Prostate gland

Document in the appropriate area in the abstract

Do not duplicate informationDocument what you know; do not

make assumptions
