California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures
This field captures the date the patient was last seen, heard from, or the date of death. It is important for researchers to calculate survival and outcome studies.
See sections Entering Dates and Date Format and Date Flag Guide for further information on coding and entering dates. Consult with your software vendor for specific data entry instructions.
Enter the most current date the patient was seen, heard from, or their date of death.
Enter the date of discharge from the reporting facility when no follow-up information has been received.
Each abstract submitted on a patient who has multiple primaries, must contain the same date of last contact.
