California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures
Casefinding (case ascertainment): The process of identifying all reportable cases through review of sources documents and case listings. Casefinding covers a range of cases that need to be accessed to determine whether or not they are reportable.
Although exact procedures might vary from reporting facility to reporting facility, they ordinarily involve careful monitoring of the records kept by the services and departments that usually provide diagnostic and treatment services to patients with cancer.
Current and previous casefinding lists are available on the SEER website: http://seer.cancer.gov
Use the casefinding lists to screen prospective reportable cancer cases.
A casefinding list is NOT the same as a reportable list.
The casefinding lists are used to identify cases seen at the reporting facility with benign or malignant tumors and/or conditions which are reportable to the CCR. This aids in the prevention of missed cases.
