Histologically confirmed cases only (n = 41,549).

Data are from population-based cancer registries that participate in National Program of Cancer Registries and/or Surveillance Epidemiology and End Results Program and meet high-quality data criteria. These registries cover 67.2% of population for 1999-2006.

Rates are per 100,000 population and are age-adjusted to 2000 US standard population. Rates and counts were suppressed if case count was <16. Case counts >1 and <16 were suppressed in tables.

CI, Confidence interval; NOS, not otherwise specified; –, rate or count suppressed (see footnote).
