Use the casefinding lists to screen prospective cases and identify cancer cases for inclusion in the registry. A casefinding list is not the same as a reportable list. Casefinding lists are intended for searching a variety of cases so as not to miss any reportable cases.
Definition of Casefinding (case ascertainment): Process of identifying all reportable cases through review of source documents and case listings. Casefinding covers a range of cases that need to be assessed to determine whether or not they are reportable.
Cancer registries and cancer surveillance programs typically describe the reportable neoplasms as any neoplasm with a behavior code (fifth digit in a complete six-digit morphology code) of '/2' (in situ) or '/3' (invasive). Some registries also collect and report the benign ('/0') and borderline ('/1') neoplasms.
Expanded versions of the casefinding lists include additional reportable terms, notes, and explanations. Short versions are provided for use in IT programming.
Refer to the Historical Staging and Coding Manuals for previous versions of the lists.
