U.S. Cancer Statistics Publication Criteria

Cancer incidence data that appear on this website are from central cancer registries that have high-quality cancer incidence data. The following are U.S. Cancer Statistics publication criteria—

  • No more than 5% of cases are ascertained solely on the basis of a death certificate.
    • A measure of the completeness of case ascertainment is the proportion of cases ascertained solely on the basis of a death certificate, with no other information on the case available after the registry has completed a routine procedure known as “death clearance and followback.”1 2 3
  • No more than 3% of cases are missing information on sex.
  • No more than 3% of cases are missing information on age.
  • No more than 5% of cases are missing information on race.
  • At least 97% of the registry’s records passed a set of single-field and interfield computerized edits.
    • Computerized edits are computer programs that test the validity and logic of data components. For example, if (a) a patient received a diagnosis of cancer in 1999, (b) the patient’s age was reported as 80 years, and (c) the patient’s year of birth was reported as 1942, a computerized edit could, without human intervention, identify these components as incompatible. The computerized edits applied to the data in this report were designed by the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program for use by SEER registries. During the 1990s, these edits were expanded and incorporated into North American Association of Central Cancer Registries (NAACCR) standards and into the NPCR–EDITS software designed and maintained by CDC.

After years of analyzing completeness of case ascertainment, CDC has determined that NPCR registries consistently deliver high-quality, complete data.47 Completeness of case ascertainment calculations have been discontinued as a measure of eligibility for publication. The data quality criteria—missing/unknown data, death-certificate-only percentage, duplicate rate, and percentage of records passing edits—will continue to be used in determining meeting or not meeting publication criteria. Even though the completeness estimate will no longer be a criterion for USCS, it will continue to be used to monitor and evaluate progress in meeting NPCR Program Standards.

Because some cancer patients receive diagnostic or treatment services at more than one reporting facility, cancer registries perform a procedure known as “unduplication” to ensure that each cancer case is counted only once.1
