Cancer Query Systems: Delay-Adjusted SEER Incidence Rates
The Canques database provides delay-adjusted rates (age-specific and age-adjusted) and the corresponding delay-adjustment
ratios. The ratio is computed as the delay-adjusted rate divided by the unadjusted rate, and is almost always greater
than one. The rates are presented by cancer site, age, race, sex, and year of diagnosis. The delay-adjusted and unadjusted
rates from the SEER Cancer Statistics Review can be obtained from this database.
The delay-adjustment ratios can be used to delay-adjust similar data.
The Canques database has:
SEER 9 delay adjusted rates and delay adjustment factors,
SEER 13-9 delay adjustment factors,
SEER 13 delay adjusted rates.
To produce SEER 13 delay adjusted rates, the methodology and formula are described in the section on the SEER 13 Delay Model page.
Visit the CanQues Web site to access other databases including those
for cancer incidence, mortality, survival and stage, lifetime risk, and prevalence statistics.
