^aData are from the New Jersey State Cancer Registry, New Jersey Department of Health and Senior Services, November 2008 analytic data file. All primary invasive cases of thyroid cancer diagnosed between 1979 and 2006 are included except death certificate only (116) and autopsy only (45) cases.
^bRates are age-adjusted to the 2000 U.S. Standard Population direct method, except rates by age, are age-specific. All rates are expressed as number of cases per 100,000 population. Age-specific rates were not calculated for men due to small numbers.
^cAAPC: Average Annual Percent Change, calculated from the National Cancer Institute’s Joinpoint software.
^dAPI is Asian and Pacific Islander; the API data are for 1997–2006 only. The ethnicity data are for 1997–2006 only, as complete ethnicity data are not available before 1990. Race and ethnicity are not mutually exclusive; the white and black race categories include white and black Hispanics.
^eICD-O-3 Codes for papillary are 8050, 8052, 8130, 8260, 8340–8344, 8350, 8450, 8452 and for follicular are 8290, 8330–8332, 8335.
^fThe 1979–2006 AAPCs should be interpreted with caution as the percentage of unknown stage was over 10% for most years 1979–1995.
*Statistically significant: the 95% confidence interval does not include 0.
