When follow-up letters are returned, the return address on the envelope should be verified against the current address recorded in the registry. A date of last contact should be requested in the letter for the patient or contact to complete. If the date is blank, the date stamped on the return envelope can be recorded as the date of last contact. Do not record the date of last contact as the date the letter was mailed to the contact or when the request was initiated. Refer to Standards of Commission on Cancer, vol. II: Registry Operations and Data Standards (ROADS), for specifications on recording returned follow-up information.
If a patient has multiple primary cancers, all records should be updated with the date of last contact. Because the status of each cancer can be different, each cancer status is updated independently.
