California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures
The principal sources for a facility's identification of cancer patients are:
Pathology reports, including histology, cytology, hematology, bone marrow, and autopsy findings. Since pathologic studies are made for most patients suspected of having cancer, the majority of reportable cases can be found by reviewing or obtaining copies of reports with positive or indicative diagnoses.
Daily facility and clinic discharges
Disease indexes (See Appendix K for applicable ICD-9-CM codes used in health information/medical record departments.)
Outpatient records
Surgery reports
Radiation therapy logs
Nuclear medicine logs
Radiology logs, including logs of scans
