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.
