Field Length: 8
Enter the month, day, and year of the last patient contact recorded at the time of abstraction. If the patient has died, the date of death should be recorded here and must be the last date of last contact recorded for this patient.
Coding Instructions
1. Code the date the patient was actually seen by the physician or contacted by the hospital registry as the follow-up date. Do not code the date the follow-up report was received.
2. Do not change the follow-up date unless new information is available
3. The data item is associated with the patient, not the cancer, so all records (primary sites) for the same patient will have the same follow-up date
4. Record the date of death for deceased patients
a. Death certificate only (DCO) cases
b. Autopsy only cases
This data item records the date of last follow-up or the date of death. SEER requires the registries to update the follow up information on all cases on an annual basis.
Survival Status for cases diagnosed prior to diagnosis year 2018 is calculated based on Date of Last Contact. For cases diagnosed in 2018 and forward, Survival Status is calculated based on Date of Last Cancer (Tumor) Status.
Date of Last Follow-Up or of Death must be transmitted in the YYYYMMDD format. Date of Last Follow-Up or of Death may be recorded in the transmission format, or recorded in the traditional format (MMDDYYYY) and converted electronically to the transmission format.
Estimating Dates
Estimating the month
1. Code “spring of” to April
2. Code “summer” or “middle of the year” to July
3. Code “fall” or “autumn” to October
4. For “winter of,” try to determine whether the physician means the first of the year or the end of the year and code January or December as appropriate. If no determination can be made, use whatever information is available to calculate the month.
5. Code “early in year” to January
6. Code “late in year” to December
7. Use whatever information is available to calculate the month
8. Code the month of admission when there is no basis for estimation
9. Leave month blank if there is no basis for approximation
Estimating the year
1. Code “a couple of years” to two years earlier
2. Code “a few years” to three years earlier
3. Use whatever information is available to calculate the year
4. Code the year of admission when there is no basis for estimation
Transmitting Dates
Transmit date data items in the year, month, day format (YYYYMMDD). Leave the year, month and/or day blank when they cannot be estimated or are unknown.
Common Formats
YYYYMMDD: Complete date is known
YYYYMM: Year and month are known/estimated; day is unknown
YYYY: Year is known/estimated; month and day cannot be estimated or are unknown
Blank: Year, month, and day cannot be estimated or are unknown
Transmit Instructions
1. Transmit date data items in the year, month, day format (YYYYMMDD)
2. Leave the year, month and/or day blank when they cannot be estimated or are unknown
3. Most SEER registries collect the month, day, and year. When the full date (YYYYMMDD) is transmitted, the seventh and eighth digits (day) will be held confidentially and only used for survival calculations when received by NCI SEER.
